Effect of comorbidity and multimorbidity on adherence to follow-up recommendations among long-term breast cancer survivors

OBJECTIVES

To study the impact of comorbidities, multimorbidity, and multimorbidity clusters on adherence to recommended follow-up guidelines among long-term breast cancer survivors.

STUDY DESIGN

Retrospective cohort study based on 2078 women diagnosed with breast cancer from 2000 to 2006 and followed up from 2012 to 2016.

MAIN OUTCOME MEASURES

Adherence to breast cancer follow-up recommendations (annual medical visit and imaging) was determined. Comorbidities were classified as acute/chronic. Multimorbidity was defined as the presence of two or more chronic comorbidities aside from breast cancer. Five multimorbidity clusters were considered. Multivariate logistic regression models were fitted to determine the relationship between adherence to recommendations and the presence of comorbidities and multimorbidity, considering both sociodemographic and clinical characteristics.

RESULTS

Overall adherence to recommendations was 79.5 %. Adherence was lower among long-term breast cancer survivors with no comorbidities (75.8 %). Among multimorbidity clusters, adherence was highest in the anxiety and fractures cluster (84.3 %) and was lowest in the musculoskeletal and cardiovascular cluster (76.4 %). In adjusted multivariate models, multimorbidity was associated with higher levels of adherence (OR = 1.52 95 %CI 1.16-1.99), and adherence was highest in the metabolic and degenerative cluster (OR = 2.2 95 %CI 1.4-3.5).

CONCLUSION

Adherence to follow-up recommendations was higher among long-term breast cancer survivors with multimorbidity than among those without. Adherence also differed by multimorbidity cluster. These results suggest suboptimal adherence to the current follow-up recommendations in certain groups, suggesting the need to adapt clinical practice guidelines to reflect patients' comorbidities and different characteristics.

Long-term survival of stage IV melanoma patients: evaluation on 640 melanoma patients entering stage IV between 2014 and 2017

PURPOSE

Since the introduction of immune checkpoint inhibitors (ICI) and targeted therapies (TT), survival rates of metastatic melanoma patients have increased significantly and complete remissions are no longer rarities. Consequently, there is an increasing number of long-term survivors who have not yet been comprehensively characterized.

METHODS

We included melanoma patients who entered stage IV between 2014 and 2017 and survived at least 5 years after entering stage IV. Descriptive statistics were performed to characterize the applied systemic therapies, response rates and to report which of these patients are still alive today.

RESULTS

640 patients entered stage IV at the University Hospital Tuebingen. Of these, 207 patients (32%) were still alive at least 5 years after entering stage IV. Details of applied therapies and response rates were available in 176 patients (85%). About 90% of patients (n = 159) were still alive at the time of analysis. Median survival since first stage IV diagnosis was 6.0 years (range 5-9 years). An impressive majority of patients (n = 146, 83%) were no longer receiving systemic therapy at the time of evaluation. Complete remission under first line systemic therapy was seen in 36% of the patients.

CONCLUSION

This dataset comprises the largest available cohort of long-term surviving stage IV melanoma patients. Since 90% of patients in our cohort are still alive today, we expect an increasing number of long-term survivors in the future. Our data indicate the need for specific follow-up programs addressing the needs of long-term survivors.

Out-of-pocket payments and loss of income among long-term breast cancer survivors in Germany: a multi-regional population-based study

PURPOSE

This study aims to examine the magnitude of out of pocket (OOP) payments and income loss, as well as to identify socioeconomic and clinical factors among long-term breast cancer (BC) survivors in Germany.

METHODS

We examine data from 2654 long-term BC survivors in Germany that participated in the "CAncEr Survivorship - A multi-Regional population-based study" (CAESAR) and who were at least 5 years post diagnosis. BC-related OOP payments and income loss both within the 12 months prior to the survey were analyzed. Two-part regression models were performed to identify socioeconomic and clinical factors.

RESULTS

OOP payments were incurred by 51.9% of survivors with a total mean spending of 566 euros. Income loss was present among 9.6% of survivors and averaged 5463 euros among those reporting such. Socioeconomic and clinical factors associated with higher OOP payments (p ≤ 0.05) included age at time of diagnosis (65-79 years), education (10-11 years), (early) retirement, stage of diagnosis (stage III), time from diagnosis (more than 10 years), comorbidities (at least 1), and the use of rehabilitation services. Regarding income loss, age at time of diagnosis (50-59 years), (early) retirement, stage of diagnosis (stage II), time from diagnosis (5-7 years), comorbidities (at least 1), and receiving chemotherapy treatment were associated with higher losses.

CONCLUSIONS

For some survivors in Germany, financial burden can be considerably high despite comprehensive healthcare and support from social security.

IMPLICATIONS FOR CANCER SURVIVORS

OOP payments related to domestic help and nursing staff as well as to outpatient care are most frequent.

Characteristics, management, and healthcare resources of patients with advanced non-small-cell lung cancer surviving 5 years after nivolumab treatment initiation: A national database analysis

BACKGROUND

Data on long-term survivors with advanced non-small-cell lung cancer (NSCLC) treated with nivolumab are available from randomized trials. Characteristics, management, and healthcare resources of those patients need to be confirmed with real-world data.

METHODS

The UNIVOC retrospective observational study included all patients with advanced NSCLC recorded in the French national hospital database starting nivolumab in 2015 and followed them until December 2020. The Kaplan-Meier method estimated the overall survival (OS). A machine learning approach identified patients with similar treatment sequences.

RESULTS

Within the 3,050 patients who had nivolumab initiation,5-year OS rate was 14.6 % (95 %CI 13.3 %-16.2 %). In total, data covering at least 5 years of follow-up were retrieved for 231 surviving patients. Survivors were younger, often female and had fewer comorbidities than non-survivors. Three clusters of patients with different nivolumab treatment durations were identified: 1/ Continuous nivolumab treatment; 2/ Long period of nivolumab treatment followed by chemotherapy or no treatment; 3/ Short period of nivolumab treatment then chemotherapy or no treatment. At 5 years, 61.0 % of survivors were no longer receiving systemic therapy, 26.4 % were treated with nivolumab, 8.7 % chemotherapy, and 3.9 % other immunotherapies. Among 5-y survivor patients, the average number of hospitalisations per patient decreased from 23.4 to 12.8 between the 1st and the 5th year. In the 5th year, 46 % of patients had no more hospitalization for lung cancer.

CONCLUSIONS

This large nationwide study confirms the long-term benefit of nivolumab treatment for advanced NSCLC patients in the real-world setting, with a 5-year survival rate similar to that reported in clinical trials.

Health care and socioeconomic costs for long-term survivors after implementation of checkpoint-inhibitors and targeted agents for metastatic melanoma

BACKGROUND

Real-life data on health care costs and loss of productivity after implementing new agents for metastatic melanoma are important to supplement model-based economic data.

MATERIALS AND METHODS

All patients registered in the Danish Metastatic Melanoma Database (DAMMED) and the National Patient Registry in 2007-2011 were compared to 2012-2016 after the implementation of checkpoint inhibitors and targeted therapy. Health care costs, social transfer income (STI), and loss of productivity were calculated with a 2-step one model generalised linear regression (GLM) model. Medicine costs were calculated separately.

RESULTS

In 2007-2011, 70 (15%) out of 464 patients were long-term survivors compared to 347 (32%) out of 1089 patients in 2012-2016. Total health care costs per patient year were significantly lower in the first treatment year (€41.457 versus €60.547, relative change (RC) 0.72, 95% confidence interval (CI) 0.56-0.94, p = 0.015) and without significant difference the second year in 2012-2016 compared to 2007-2011. Medicine costs per patient year increased the first (€85.464 versus €26.339, RC 3.39, 95% CI 2.61-4.41, p < 0.001) and the second (€26.464 versus €11.150, RC 2.59, 95% CI 1.98-3.40, p < 0.001) year in 2012-2016 compared to 2007-2011. Productivity increased for long-term survivors in 2012-2016 in contrast to 2007-2011.

CONCLUSION

Implementation of targeted therapy and checkpoint-inhibitors has increased medicine costs more than three-fold for long-term survivors. Total health care costs excluding medicine costs were significantly lower for long-term survivors the first and without change the second treatment year in 2012-2016 compared to 2007-2011. However, the number of treated patients increased which leads to an increase in overall total health care costs. Importantly, productivity increased for long-term survivors in 2012-2016.

Long-Term Immunity Against Tetanus and Diphtheria after Vaccination of Allogeneic Stem Cell Transplantation Recipients

Revaccination against tetanus and diphtheria after allogeneic hematopoietic stem cell transplantation (HCT) is usually effective, but the duration of the immunity is unknown. We conducted this study to evaluate humoral immunity to tetanus and diphtheria in long-term survivors and to provide knowledge regarding the need for boosters. The median time from HCT to blood sampling was 14 years (range, 8 to 40 years). All patients had received at least 3 doses of vaccines against both tetanus and diphtheria, either monovalent or combination vaccines containing a full dose of the diphtheria toxoid component. In addition, 1 or more booster doses were administered to 21 of the 146 patients (14%). On enzyme-linked immunosorbent assay, levels <.1 IU/mL for diphtheria and <.01 IU/mL for tetanus were considered low or seronegative. Values between .01 and .5 IU/mL for tetanus and between .1 and 1.0 IU/mL for diphtheria were considered to represent partial protection, and levels >.5 and >1.0 IU/mL were considered high and protective, respectively. In all, 39% of patients were seronegative against diphtheria, 52% had some protection, and 9% had a high titer. In contrast, no patient had become seronegative to tetanus, 32% had "partial protection" against tetanus and 68% had a high titer. In multivariate analysis, active graft-versus-host-disease, sex, or time from sampling did not affect the probability of becoming seronegative or seropositive. Younger age was associated with lower antibody levels to tetanus toxoid, but age was not correlated with antibody levels against diphtheria toxoid. Tetanus immunity was maintained after vaccination in most long-term survivors, but immunity against diphtheria was poor, and boosters should be considered.

Long-term physical impairments in survivors of COVID-19-associated ARDS compared with classic ARDS: A two-center study

PURPOSE

This work aimed to compare physical impairment in survivors of classic ARDS compared with COVID-19-associated ARDS (CARDS) survivors.

MATERIAL AND METHODS

This is a prospective observational cohort study on 248 patients with CARDS and compared them with a historical cohort of 48 patients with classic ARDS. Physical performance was evaluated at 6 and 12 months after ICU discharge, using the Medical Research Council Scale (MRCss), 6-min walk test (6MWT), handgrip dynamometry (HGD), and fatigue severity score (FSS). We also assessed activities of daily living (ADLs) using the Barthel index.

RESULTS

At 6 months, patients with classic ARDS had lower HGD (estimated difference [ED]: 11.71 kg, p < 0.001; ED 31.9% of predicted value, p < 0.001), 6MWT distance (ED: 89.11 m, p < 0.001; ED 12.96% of predicted value, p = 0.032), and more frequent significant fatigue (OR 0.35, p = 0.046). At 12 months, patients with classic ARDS had lower HGD (ED: 9.08 kg, p = 0.0014; ED 25.9% of predicted value, p < 0.001) and no difference in terms of 6MWT and fatigue. At 12 months, patients with classic ARDS improved their MRCss (ED 2.50, p = 0.006) and HGD (ED: 4.13 kg, p = 0.002; ED 9.45% of predicted value, p = 0.005), while those with CARDS did not. Most patients in both groups regained independence in ADLs at 6 months. COVID-19 diagnosis was a significant independent predictor of better HGD (p < 0.0001) and 6MWT performance (p = 0.001), and lower prevalence of fatigue (p = 0.018).

CONCLUSIONS

Both classic ARDS and CARDS survivors experienced long-term impairments in physical functioning, confirming that post-intensive care syndrome remains a major legacy of critical illness. Surprisingly, however, persisting disability was more common in survivors of classic ARDS than in CARDS survivors. In fact, muscle strength measured with HGD was reduced in survivors of classic ARDS compared to CARDS patients at both 6 and 12 months. The 6MWT was reduced and fatigue was more common in classic ARDS compared to CARDS at 6 months but differences were no longer significant at 12 months. Most patients in both groups regained independent function in ADLs at 6 months.

Multicentre match-paired analysis of advanced biliary cancer long-term survivors: The BILONG study

BACKGROUND

Advanced biliary cancers (ABC) are aggressive malignancies with a median overall survival (mOS) <12 months when treated with first-line chemotherapy. Nevertheless, a subset of patients experiencing longer survival has been described in the updated analysis of ABC-02 trial. We aimed to provide a real-world description of ABC long-term survivors (LS), identifying which factors impact on survival.

METHODS

Patients diagnosed with ABC at three Institutions between 2002 and 2019, and who survived ≥18 months, were retrospectively identified. We compared them with a control cohort (C) with a mOS <18 months, matched on age, gender, ECOG PS, disease status, primary tumor site, prior surgery, and treatment modality. Their clinical features, treatments, and outcome were analyzed.

RESULTS

A total of 78 patients was included, 39 in each group. Both LS and C cohorts had superimposable baseline characteristics, without significant differences. mOS was 29 (95%CI 24.6-33.5) and 9 months (95%CI 6.6-12.9) in the two groups, respectively. After performing a logistic regression analysis, three factors were significantly associated with long-term outcome: low neutrophil-to-lymphocyte ratio (NLR < 3) (Odds Ratio [OR] 0.38), achievement of objective response to treatment (OR 0.16), and the number of lines received (OR 0.29).

CONCLUSIONS

We described a considerable subset of ABC experiencing long-term survival with conventional chemotherapy in a real-world scenario. Beyond clinical factors, we identified low NLR as a prognostic determinant that may allow for a more accurate selection of long survivors. While waiting for a deeper molecular characterization of this subgroup, we propose NLR as a stratification factor for daily practice and clinical trials.

Quality of life in adolescents who underwent congenital diaphragmatic hernia surgical repair

OBJECTIVE

The advances made in the surgical and postnatal treatment of congenital diaphragmatic hernia (CDH) have considerably improved patient survival, but morbidity remains significant. The objective of this study was to analyze the effect these sequels have on the health-related quality of life (HRQL) of adolescents and young adults who have survived CDH, and to compare it with that of the general population.

MATERIALS AND METHODS

A transversal descriptive study of patients diagnosed with CDH in our institution from 1997 to 2004 was carried out. Survival, location, hernia size, herniated organs, need for extracorporeal membrane oxygenation, and mechanical ventilation time were analyzed. In addition, a comparative study of the current HRQL of survivors was conducted using the SF-36 survey (36-Item Health Survey Short Form), which assessed physical function, physical role, body pain, general health, vitality, social function, emotional role, and mental health. Data of 24 healthy adolescents was used as a control group.

RESULTS

Of the 29 survivors (70.7%), 21 were successfully contacted, and 16 responded to the survey. They all claimed their overall quality of life was good or very good. The group of adolescents who underwent CDH surgical repair had better results in the vitality (p= 0.001) and mental health (p<0.05) areas, but the overall HRQL score and the remaining health areas were similar. No significant differences were found regarding diaphragmatic size or need for ECMO.

CONCLUSION

According to adolescent survivors who underwent CDH surgical repair, their quality of life is similar to that of other individuals of their age. Our results are encouraging and may prove useful for future parents of CDH patients.

Adherence of long-term breast cancer survivors to follow-up care guidelines: a study based on real-world data from the SURBCAN cohort

Purpose

To identify adherence to follow-up recommendations in long-term breast cancer survivors (LTBCS) of the SURBCAN cohort and to identify its determinants, using real-world data.

Methods

We conducted a retrospective study using electronic health records from 2012 to 2016 of women diagnosed with incident breast cancer in Spain between 2000 and 2006 and surviving at least 5 years. Adherence to basic follow-up recommendations, adherence according to risk of recurrence, and overall adherence were calculated based on attendance at medical appointments and imaging surveillance, by year of survivorship. Logistic regression models were fitted to depict the association between adherence and its determinants.

Results

A total of 2079 LTBCS were followed up for a median of 4.97 years. Of them, 23.6% had survived ≥ 10 years at baseline. We estimated that 79.5% of LTBCS were overall adherent to at least one visit and one imaging test. Adherence to recommendations decreased over time and no differences were found according to recurrence risk. Determinants of better overall adherence were diagnosis in middle age (50–69 years old), living in a more-deprived area, having fewer years of survival, receiving primary treatment, and being alive at the end of follow-up.

Conclusion

We identified women apparently not complying with surveillance visits and tests. Special attention should be paid to the youngest and eldest women at diagnosis and to those with longer survival.

[Content validation of the spanish version of the Long-term Quality of Life Instrument for long-term female breast cancer survivors.]

OBJECTIVE

The quality of life of women affected by breast cancer diagnosed 5 or more years ago has been relatively unexplored in Spain; there are no instruments for its measurement validated. The objective of the study is to translate into Spanish, culturally adapt and examine the content validity of the Spanish version of the Long-Term Quality of Life Instrument (LTQL).

METHODS

The initial translation was performed by two translators with Spanish as their mother tongue carried out the translation of the questionnaire, obtaining two initial versions in Spanish (T1 and T2). An analysis of the results and elaboration of a single preliminary version in Spanish (T-1-2) were performed. The retro-translation was performed by two translators with English as their mother tongue not familiar with the original version translated the joint version (T-1-2) back into the original language (RT1 and RT2) to identify inconsistencies. Finally, a final version of the questionnaire was obtained. For content validation a committee of experts (seven women affected by breast cancer) assessed the degree of clarity, accuracy and understanding of each of the items in the questionnaire translated into Spanish, and calculated the content validity index (CVI) of the questionnaire according to Lawshe and Tristán.

RESULTS

The LTQL questionnaire was translated into Spanish with a low discrepancy between translators. An adequate CVI higher than 0.58 was obtained in clarity (0.95), precision (0.93), comprehension (0.91) and relevance (0.72).

CONCLUSIONS

The LTQL is a useful questionnaire in the health field for the assessment of quality of life of women survivors of long-term breast cancer.

Oral chronic GVHD after allogeneic stem cell transplantation without total body irradiation performed at a young age

Purpose

Long-term survivors (LTSs) of allogeneic hematopoietic stem cell transplantation (allo-HCT) may experience oral long-term effects like chronic graft-versus-host disease (oral cGVHD). The aim of this study was to investigate oral cGVHD in patients treated at a young age (< 30 years) more than 5 years after allo-HCT without total body irradiation (TBI).

Methods

All 94 participants went through a semi-structured interview, and an oral examination. Diagnosis of oral cGVHD was based on the “National Institutes of Health (NIH) cGVHD diagnosis and staging consensus criteria” from 2014.

Results

Mean age at transplantation was 17.5 years (range 0.4–29.9 years), and mean time since transplantation was 16.7 years (range 6–26 years). Oral cGVHD was diagnosed in 26 (28%) of 94 LTSs. Of which 20 (21.5%) showed lichen planus-like (LPL) changes, and additionally six (6.5%) also fulfilled the diagnostic criteria of oral cGVHD since they had one or more distinctive signs and symptoms of oral cGVHD combined with definite cGVHD in another organ. No LTSs reported oral cGVHD (NIH) grade 3. There was a significant association between cGVHD in the oral cavity and cGVHD in another organ (77% vs 29%, p < 0.001). Out of 72 LTSs, who answered the questions regarding taste disturbances, 16 (22%) reported dysgeusia. No LTSs developed secondary malignancies in the oral cavity during follow-up time.

Conclusion

Oral long-term effects, such as oral cGVHD, may persist for many years after allo-HCT without TBI-conditioning in patients treated at a young age.

Distress, anxiety, depression and unmet needs in thyroid cancer survivors: a longitudinal study

PURPOSE

Despite a good prognosis, thyroid cancer (TC) survivors often report psychological distress and decreased quality of life. This longitudinal study aims to evaluate TC survivors' levels of distress, anxiety, depression and unmet needs, checking potential life events.

METHODS

Distress Thermometer, Hospital Anxiety Depression Scale, Supportive Care Need Survey (short form) and Interview for Recent Life Events were administered to 73 TC survivors (T0) and 44 of them were re-tested one year later (T1). Participants were at 0-5, 5-10 or >10 years from the end of their cancer-related treatments.

RESULTS

At T0, distress, anxiety and depression mean scores were 6.4, 6.8 and 5.3, while at T1 they were 5.5, 4.8 and 5.1. Only anxiety scores decreased significantly between T0 and T1. 50.7% of patients had unmet psychological needs at T0 and 50.0% at T1. Most participants were satisfied in the communicative/ informative (T0:79.5%; T1: 77.3%) and social/health care areas (T0:74.0%; T1:75.0%). The most experienced stressful events detected concerned their working areas.

CONCLUSIONS

Results confirmed that patients reported distress, anxiety and depression concerns even many years after the end of treatments. Both medical and psychological surveillance are relevant to improving TC survivors' wellbeing.

Symptom burden, psychological distress, and health-related quality of life in cancer survivors with pelvic late radiation tissue injuries

Purpose

Curative radiotherapy for cancer may lead to severe late radiation tissue injuries (LRTIs). However, limited knowledge exists about pelvic cancer survivors’ LRTI symptoms, distress, and health-related quality of life (HRQOL). We sought to assess the symptom burden, distress, and HRQOL in survivors with established pelvic LRTIs compared to norm populations and to investigate the relation between these factors.

Methods

Cancer survivors referred for treatment of established pelvic LRTIs were recruited nationwide. LTRIs were assessed with the Expanded Prostate Cancer Index Composite (EPIC), psychological distress was assessed with the General Health Questionnaire (GHQ-12), and HRQOL was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORCT-QLQ-C30).

Results

A total of 107 participants (mean age 64, 53% men) were included. Compared to norms, participants reported more urinary (mean 68.7 vs. 89.5; p = 0.00; d = 1.4) and bowel symptoms (mean 62.5 vs. 92.4; p = 0.00; d = 2.7), increased psychological distress (mean 13.4 vs. 10.3; p = 0.00; d = 0.6), and overall poorer HRQOL (mean 54.9 vs. 71.2; p = 0.00; d = 0.7). Higher symptom burden and higher levels of psychological distress were associated with lower HRQOL (r² = 46%), but psychological distress did not moderate the influence of symptoms on HRQOL.

Conclusion

Cancer survivors with established pelvic LRTIs are highly burdened compared to norms. The association of the LRTI-related symptom burden with HRQOL is independent of the level of psychological distress. Both coping and treatment interventions are crucial to promoting long-term health and HRQOL.

Outcomes of long-term nivolumab and subsequent chemotherapy in Japanese patients with head and neck cancer: 2-year follow-up from a multicenter real-world study

Background

We have previously reported the effectiveness and safety of nivolumab in patients with head and neck cancer (HNC) in real-world clinical practice in Japan. Here, we report long-term outcomes from this study in the overall population and subgroups stratified by subsequent chemotherapy.

Methods

In this multicenter, retrospective observational study, Japanese patients with recurrent or metastatic (R/M) HNC receiving nivolumab were followed up for 2 years. Effectiveness endpoints included overall survival (OS), OS rate, progression-free survival (PFS), and PFS rate. Safety endpoints included the incidence of immune-related adverse events (irAEs).

Results

Overall, 256 patients received a median of 6.0 doses (range: 1–52) of nivolumab over a median duration of 72.5 days (range: 1–736). Median OS was 9.5 months [95% confidence interval (CI) 8.2–12.0] and median PFS was 2.1 months (95% CI 1.8–2.7). A significant difference between 2-year survivors (n = 62) and non-2-year survivors was observed by median age (P = 0.0227) and ECOG PS (P = 0.0001). Of 95 patients who received subsequent chemotherapy, 54.7% received paclitaxel ± cetuximab. The median OS and PFS from the start of paclitaxel ± cetuximab were 6.9 months (95% CI 5.9–11.9) and 3.5 months (95% CI 2.3–5.5), respectively. IrAEs were reported in 17.2% of patients. Endocrine (7.0%) and lung (4.3%) disorders were the most common irAEs; kidney disorder (n = 1) was newly identified in this follow-up analysis.

Conclusions

Results demonstrated the long-term effectiveness of nivolumab and potential effectiveness of subsequent chemotherapy in patients with R/M HNC in the real-world setting. Safety was consistent with that over the 1-year follow-up.

Clinical-pathological and molecular characterization of long-term survivors with advanced non-small cell lung cancer

Objective: Long-term survivors (LS) of non-small cell lung cancer (NSCLC) without driver alterations, displaying an overall survival (OS) of more than 3 years, comprise around 10% of cases in several series treated with chemotherapy. There are classical prognosis factors for these cases [stage, Eastern Cooperative Oncology Group (ECOG), etc.], but more data are required in the literature. In this multi-center study, we focused on LS of advanced NSCLC with OS above 36 months to perform a clinical-pathological and molecular characterization.

Methods: In the first step, we conducted a clinical-pathological characterization of the patients. Afterwards, we carried out a genetic analysis by comparing LS to a sample of short-term survivors (SS) (with an OS less than 9 months). We initially used whole-genome RNA-seq to identify differentiating profiles of LS and SS, and later confirmed these with reverse transcription-polymerase chain reaction (RT-PCR) for the rest of the samples.

Results: A total of 94 patients were included, who were mainly men, former smokers, having adenocarcinoma (AC)-type NSCLC with an ECOG of 0–1. We obtained an initial differential transcriptome expression, displaying 5 over- and 33 under-expressed genes involved in different pathways: namely, the secretin receptor, surfactant protein, trefoil factor 1 (TFF1), serpin, Ca-channels, and Toll-like receptor (TLRs) families. Finally, RT-PCR analysis of 40 (20 LS/20 SS) samples confirmed that four genes (surfactant proteins and SFTP) were significantly down-regulated in SS compared to LS by using an analysis of covariance (ANCOVA) model: SFTPA1 (P = 0.023), SFTPA2 (P = 0.027), SFTPB (P = 0.02), and SFTPC (P = 0.047).

Conclusions: We present a sequential genetic analysis of a sample of NSCLC LS with no driver alterations, obtaining a differential RNA-seq/RT-PCR profile showing an abnormal expression of SF genes.

Metabolic Syndrome in Male Survivors of Pediatric Allogeneic Hematopoietic Stem Cell Transplantation: Impact of Total Body Irradiation, Low-Grade Inflammation, and Hypogonadism

Metabolic syndrome (MetS) is a growing concern in survivors of pediatric hematopoietic stem cell transplantation (HSCT), but little is known about the underlying mechanisms. This study aimed to determine the prevalence and clinical presentation of MetS in male long-term survivors of pediatric HSCT and to investigate predisposing factors, including low-grade inflammation, altered fat distribution, and low testosterone levels. We included 98 survivors age 19 to 47 years at a median follow-up of 18 years (range, 8 to 35 years) after pediatric HSCT. MetS was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria. The prevalence and clinical manifestations of MetS were compared between our cohort and a control group of males from the background population (n = 4767). Fat distribution was assessed by android/gynoid ratio from a whole-body dual-energy X-ray absorptiometry scan. Systemic inflammation was evaluated by IL-6 and high-sensitivity C-reactive protein (hsCRP). Serum testosterone levels were measured in morning samples. The prevalence of MetS was 30%, corresponding to the prevalence in the 50- to 80-year-old males from the background population. In individuals with MetS, hyperglycemia was more frequent in the HSCT survivors compared with age-matched controls with MetS (76% versus 20%; P < .001), whereas hypertension was more dominant in the control group with MetS (69% versus 93%; P = .01). In addition, normal or low body mass index was more commonly observed among HSCT survivors with MetS compared with age-matched controls with MetS (41% versus 11%; P = .002). MetS was more often associated with total body irradiation (TBI) compared with chemotherapy regimens (odds ratio [OR], 4.3; 95% confidence interval [CI], 1.2 to 24.4; P = .02), lower testosterone levels (OR, 5.4; 95% CI, 1.3 to 23.6; P = .02), higher IL-6 levels (OR, 1.8; 95% CI, 1.2 to 2.8; P = .004), and higher hsCRP levels (OR, 1.8; 95% CI, 1.3 to 2.6; P < .001) (estimates per 2-fold increase). In addition, an increased android/gynoid (AG) fat ratio was strongly associated with MetS (OR, 2.1; 95% CI, 1.5 to 2.9; P < .001), even though only 7% of patients met the criteria for increased abdominal circumference. Our results indicate an increased risk of MetS in early adulthood after pediatric HSCT. The clinical manifestations differed from those seen in age-matched controls with MetS, indicating different pathophysiology driven by hyperglycemia, altered fat distribution (despite no clinical abdominal obesity), and low-grade inflammation. Risk factors included TBI-based conditioning and low testosterone levels. These results underline the importance of continuous clinical assessment of the cardiometabolic risk profile and stress the presence of important dissimilarities in the pathophysiology of MetS in HSCT survivors compared with the background population.

Determining the Factors Affecting Long-Term and Short-Term Survival of Breast Cancer Patients in Rafsanjan Using a Mixture Cure Model

BACKGROUND

Breast cancer is one of the most common causes of death among women worldwide and the second leading cause of death among Iranian women. The incidence of this malignancy in Iran is 22 per 100,000 women. These patients have long-term survival time with advances in medical sciences. The present study aimed to identify the risk factors of breast cancer using Cox proportional hazard and Cox mixture cure models.

STUDY DESIGN

It is a retrospective cohort study.

METHODS

In this cohort study, we recorded the survival time of 140 breast cancer patients referred to Ali Ibn Abitaleb Hospital in Rafsanjan, Iran, from 2001 to 2015. The Kaplan-Meier curve was plotted; moreover, two Cox proportional hazards and the Cox mixture cure models were fitted for the patients. Data analysis was performed using SAS 9.4 M5 software.

RESULTS

The mean age of patients was reported as 47.12 ±12.48 years at the commencement of the study. Moreover, 83.57% of patients were censored. The stage of disease was a significant variable in Cox and the survival portion of Cox mixture cure models (P=0.001). The consumption of herbal tea, tumor size, duration of the last lactation, family history of cancer, and the type of treatment were significant variables in the cured proportion of the Cox mixture cure model (P=0.001).

CONCLUSION

The Cox mixture cure model is a flexible model which is able to distinguish between the long-term and short-term survival of breast cancer patients. For breast cancer patients, cure effective factors were the stage of the disease, consumption of herbal tea, tumor size, duration of the last lactation, family history, and the type of treatment.

Critical review of oncology clinical trial design under non-proportional hazards

In trials of novel immuno-oncology drugs, the proportional hazards (PH) assumption often does not hold for the primary time-to-event (TTE) efficacy endpoint, likely due to the unique mechanism of action of these drugs. In practice, when it is anticipated that PH may not hold for the TTE endpoint with respect to treatment, the sample size is often still calculated under the PH assumption, and the hazard ratio (HR) from the Cox model is still reported as the primary measure of the treatment effect. Sensitivity analyses of the TTE data using methods that are suitable under non-proportional hazards (non-PH) are commonly pre-planned. In cases where a substantial deviation from the PH assumption is likely, we suggest designing the trial, calculating the sample size and analyzing the data, using a suitable method that accounts for non-PH, after gaining alignment with regulatory authorities. In this comprehensive review article, we describe methods to design a randomized oncology trial, calculate the sample size, analyze the trial data and obtain summary measures of the treatment effect in the presence of non-PH. For each method, we provide examples of its use from the recent oncology trials literature. We also summarize in the Appendix some methods to conduct sensitivity analyses for overall survival (OS) when patients in a randomized trial switch or cross-over to the other treatment arm after disease progression on the initial treatment arm, and obtain an adjusted or weighted HR for OS in the presence of cross-over. This is an example of the treatment itself changing at a specific point in time - this cross-over may lead to a non-PH pattern of diminishing treatment effect.

Glioblastoma in adolescents and young adults: An age-based comparative study from Jordan over a 17-year period

BACKGROUND

Glioblastoma (GBM) is the most common primary brain tumor. Epidemiologic studies on GBM are rarely reported in the special age group of adolescents and young adults (AYA) in comparison to other age groups. We aim to present data on GBM in Jordan, with a focus on the AYA age, including the incidence, gender, location and outcome, as well as long term survival (LTS).

METHODS

Data on GBM was requested from the Jordan Cancer Registry (JCR), and statistical analysis was performed. All data were retrospective and anonymized.

RESULTS

Eight hundred GBM cases were analyzed from 2000 to 2016 including 505 males (63.1 %). Males outnumbered females across are studied years (p-value <0.001). There were 49 pediatrics (0-14 years, 6.1 %), 125 AYA (15-39 years, 15.6 %), 358 adults (40-59 years, 44.8 %) and 268 elderly (60+ years, 33.5 %) cases. Supratentorial location predominated across all age groups (p-value <0.001). The preponderance of males and supratentorial tumors remained across the AYA age group in comparison to others. The median overall survival (OS) was 23.61 months. AYA age group had a better outcome in comparison to the adults/elderly age group (p-value< 0.001). LTS appear to be more common in the AYA age group (p-value 0.021).

CONCLUSIONS

This is the first comparative epidemiologic study of GBM in Jordan, focusing on the AYA age group. The AYA age group appears to be associated with a better outcome compared to older age groups, with more LTS compared to others.

Screening colonoscopy according to guidelines in long-term survivors of childhood cancer-results of a population-based study

PURPOSE

To report on findings in screening colonoscopies in long-term survivors of childhood cancer treated with abdominopelvic irradiation (RT).

METHODS

Screening colonoscopies were introduced at the Slovenian outpatient follow-up clinic in 2015, according to the Children's Oncology Group guidelines. In January 2019, 54 patients who received abdominopelvic irradiation for Hodgkin disease, Wilms tumour or dysgerminoma at the age of 0-16 between 1968 and 1995 were eligible for screening colonoscopy, and until December 2019, twenty-eight asymptomatic patients have undergone this examination.

RESULTS

Patients were 1-16 (median 13) years old at cancer diagnosis and had colonoscopy 24-47 (median 36) years after diagnosis. They received abdominopelvic irradiation with the dose 16-46 (median 30) Gy. Adenomatous lesions were found in 18 patients (64%) and advanced adenomatous lesions in one-third. Patients who received abdominopelvic RT with a dose below 30 Gy had 75% incidence of adenomatous lesions and in those who received a dose of 30 Gy or more the incidence was 60%. Alkylating agents did not have impact on this incidence.

CONCLUSIONS

In this first population-based study of screening colonoscopies in asymptomatic survivors of childhood cancer, we provided new evidence for 64% incidence of adenomatous lesions after abdominopelvic RT with the dose above or below 30 Gy.

IMPLICATIONS FOR CANCER SURVIVORS

Screening colonoscopies are of vital importance in patients treated with abdominal RT in childhood.

Assessment of prognostic factors in long-term survival of male and female patients with colorectal cancer using non-mixture cure model based on the Weibull distribution

OBJECTIVE

Colorectal cancer (CRC) is known as one of the malignant form of cells growing in the inner lining of colon and rectum which could seriously affect the cure rate of patients. We aimed to evaluate the effect of prognostic factors on cure fraction of CRC patients.

METHODS

A total of 1043 CRC patients were included to the study from December 2001 to January 2007 at the Research Center of Gastroenterology and Liver Disease in Shahid Beheshti University of Medical Sciences, Tehran, Iran. Patients' information was extracted from their medical records, then they were followed to identify their death status via phone-call. Weibull non-mixture cure model was used to evaluate the effect of the risk factors on cure fraction of CRC patients.

RESULTS

The five-years survival rate was 0.66 (males: 0.64 and female: 0.69). The median survival time for non-cured CRC patients were 3.45 years (males: 3.46; females = 3.45 years). In the single Weibull model, BMI≥30 (OR = 4.61, p-value = 0.033), poorly differentiated tumor grade (OR = 0.36, p-value = 0.036), tumor size≥25 mm (OR = 0.22, p-value = 0.046), and N1-stage (OR = 0.42, p-value = 0.005) had significant effect on females' cure fraction. Also, cure fraction of male CRC patients significantly affected by BMI (levels:25.0-29.9-OR = 12.13-p-value<0.001; ≥30-OR = 7.00-p-value = 0.017), T1-stage (OR = 0.52, p-value = 0.021), M1-stage (OR = 0.45, p-value = 0.007), IV-staging (OR = 0.36, p-value = 0.041) and IBD (OR = 0.26, p-value = 0.017). In multiple Weibull model, females were associated with tumor size≥25 mm (OR = 0.20, p-value = 0.044) and N1-stage (OR = 0.45, p-value = 0.013) and males were affected by M1-stage (OR = 0.41, p-value = 0.011) and IBD (OR = 0.20, p-value = 0.022).The cure fraction of males and females CRC patients was 64% and 69%, respectively.

CONCLUSIONS

The prognostic factors for cure fraction of patients with CRC may be different among males and females. Further multicenter studies are required to assess the effect of common prognostic factors between males and females.

Red propolis effect analysis of dairy calves health based on Weibull regression model with long-term survivors

Diarrhea is the most common cause of mortality and morbidity in dairy calves during the first weeks of life. It is responsible for the majority of costs related to animal death and treatments, as well as lower productivity due to reduced weight gain. Therefore, studies that focus on strategies to reduce diarrhea incidence and to improve animal welfare are very important for the dairy industry. For that reason, the beneficial effects of red propolis on the health status of preweaned dairy calves was studied. Animal disease data usually present incomplete observations of interest time, so-called censored observations and one of the statistical techniques for this modeling type is the survival analysis, hence it is a set of methods for analyzing data where the response variable is the time until the occurrence of an event of interest. We propose among some methods of survival data analysis, the long-term models. The motivation to study these models is the fact that part of the population is not susceptible to the event of interest during the period of the study, considered as immune or cured. In this paper, we studied the Weibull distribution in a structure of long-term model, including the covariates in the proportion of cured through the logistic link function. Besides, we used the residual analysis to check the assumptions of the model. The reason for the choice of the Weibull distribution was that this model is very flexibility to model a variety of data sets, among them animal science and long-term survival data. We illustrate its application with a case study from an animal experiment, which examined the time till the occurrence of diarrhea in Holstein calves, where a proportion of the animals were not susceptible to this health condition. This experiment aimed to verify the efficiency of red propolis in disease prevention and the influence of that on the proportion of animals that are not susceptible to diarrhea.

Chemotherapy-induced amenorrhea and its effects on fertility in long-term female survivors of classic osteosarcoma

PURPOSE

To explore the effect of chemotherapy-induced amenorrhea (CIA) on female osteosarcoma patients' fertility function, we investigated and analyzed their marital status, fertility, and menstrual status in a retrospective cohort study.

METHODS

We selected female osteosarcoma patients from database from January 2004 to December 2013. Patients' characteristics such as age, tumor location, marital status, menstrual status, and fertility status were collected. The data were analyzed using the Statistical Package for the Social Sciences (SPSS), version 22.

RESULTS

A total of 122 female patients met these criteria and finally responded by questionnaire and telephone follow-up. The marriage rate of female osteosarcoma survivors was 50.8% (62/122), which was significantly lower than the control group (p = 0.000). The average marriage age of female osteosarcoma survivors was 25.5, which was obviously higher than the control group (p = 0.000). CIA occurred in 46 (36.1%) patients. We then found that the incidence of CIA was higher in older patients. (p = 0.011). All of the married patients wanted to have children, and 67.8% (42/62) of them had given birth after chemotherapy. The fertility of married patients with CIA was significantly reduced compared to that of married patients without CIA. (p = 0.001).

CONCLUSIONS

The patients with CIA have higher risk of impaired reproductive function than those who did not. Fertility preservation option before the start of the chemotherapy is important. And it is much value to record menstrual pattern and detect sex steroid levels after 6 months of therapy in order to be able to evaluate the fertility status.

A long-term trajectory of bone mineral density in childhood cancer survivors after discontinuation of treatment: retrospective cohort study

Low bone mineral density (BMD) was diagnosed in 24% of childhood cancer survivors (CCS), whereas very low BMD was relatively uncommon at 8%. We suggest that low BMD in CCS may become alleviated over time. Stem cell transplantation, radiotherapy, and underweight were the strongest independent predictors of decreased BMD.

PURPOSE

Childhood cancer survivors (CCS) are at risk of premature bone loss, although published studies are inconsistent. The objective of this study was to evaluate the prevalence and pattern of low bone mineral density (BMD) in short- and long-term CCS, and to determine clinical factors affecting skeleton after anticancer treatment.

METHODS

This retrospective study was conducted in a cohort of 326 children and young adult CCS (147 females) who completed anticancer treatment. BMD was determined by dual-energy X-ray absorptiometry (DXA). Low BMD was defined as a Z-score ≤ - 1.0, and the very low BMD as a Z-score ≤ - 2.0. Additionally, the changes in BMD over time were studied in 123 CCS who had been re-examined by DXA during follow-up.

RESULTS

Median age at diagnosis was 7.27 years (range, 4.4-10.6); median time between end of treatment and DXA was 6.12 (range, 4.0-22.0). Low BMD was found in 24% of CCS, while very low BMD was relatively uncommon (8%). Based on multivariate analysis, the following were significantly associated with low BMD at the follow-up: hematopoietic stem cell transplantation (OR 3.13, 95% CI 1.02-9.63), head and neck radiotherapy (OR 2.54, 95% CI 1.32-4.90), and body weight below the standard reference (OR 3.57, 95% CI 1.24-10.23). The time-related trajectory showed an improvement (BMD_LS) or stabilization (BMD_TB) in Z-scores values.

CONCLUSION

These data based on serial DXA measurements, encompassing a long-lasting observation period, show that CCS may not be at risk of premature bone loss in young adulthood. However, it is unknown how the scenario for skeletal mass is until the CCS will achieve older or postmenopausal age.

Thirty-three long-term survivors after cytoreductive surgery in patients with peritoneal metastases from colorectal cancer: a retrospective descriptive study

BACKGROUND

Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) improves survival in selected patients with peritoneal metastasis (PM) from colorectal cancer (CRC). However, little has been reported on characteristics and clinical course of long-term survivors with CRC-PM beyond 5 years. The objective of this study was to identify the clinical and oncological features affecting long-term survival of CRC-PM after comprehensive treatment.

METHODS

Between January 1990 and April 2015, CRC-PM patients who underwent CRS with or without HIPEC in two Japanese tertiary hospitals were analyzed. Clinicopathological parameters and therapeutic details for long-term survivors (patients surviving ≥ 5 years after CRS) were described and compared with those for non-survivors (patients surviving < 5 years).

RESULTS

The study identified 236 patients with CRC-PM who underwent CRS, with a median follow-up period of 2.5 years. Thirty-three patients (14.0%) were considered as long-term survivors. Compared with non-survivors, long-term survivors had a lower median peritoneal cancer index (PCI) [4 (1-27) vs 9 (0-39), p < 0.001]. Complete cytoreduction (CCR-0) was achieved in all long-term survivors, with a significantly higher rate [33/33 (100%) vs 141/203 (69.8%), p < 0.001]. Metachronous onsets of PM were more frequently observed in the long-term survivor group [26/33 (78.8%) vs 103/203 (50.3%), p = 0.018]. Regarding histopathology, long-term survivors more frequently had mucinous adenocarcinoma than non-survivors [8/33 (24.2%) vs 27/203 (13.3%)] and less likely exhibited poorly differentiated or signet ring cell carcinoma [2/33 (6.1%) vs 48/203 (23.7%)] (p < 0.001).

CONCLUSIONS

One in seven patients with CRC-PM achieved the long-term milestone after CRS. A long-term survival was associated with the presence of low PCI, CCR-0, metachronous onset, and mucinous histology.

Heterogeneity in Quality of Life of Long-Term Colon Cancer Survivors: A Latent Class Analysis of the Population-Based PROFILES Registry

Background

Long‐term colon cancer survivors present heterogeneous health‐related quality of life (HRQOL) outcomes. We determined unobserved subgroups (classes) of survivors with similar HRQOL patterns and investigated their stability over time and the association of clinical covariates with these classes.

Materials and Methods

Data from the population‐based PROFILES registry were used. Included were survivors with nonmetastatic (TNM stage I–III) colon cancer (n = 1,489). HRQOL was assessed with the Dutch translation of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 version 3.0. Based on survivors’ HRQOL, latent class analysis (LCA) was used to identify unobserved classes of survivors. Moreover, latent transition analysis (LTA) was used to investigate changes in class membership over time. Furthermore, the effect of covariates on class membership was assessed using multinomial logistic regression.

Results

LCA identified five classes at baseline: class 1, excellent HRQOL (n = 555, 37.3%); class 2, good HRQOL with prevalence of insomnia (n = 464, 31.2%); class 3, moderate HRQOL with prevalence of fatigue (n = 213, 14.3%); class 4, good HRQOL with physical limitations (n = 134, 9.0%); and class 5, poor HRQOL (n = 123, 8.3%). All classes were stable with high self‐transition probabilities. Longer time since the diagnosis, no comorbid conditions, and male sex were associated with class 1, whereas older age was associated with class 4. Clinical covariates were not associated with class membership.

Conclusion

The identified classes are characterized by distinct patterns of HRQOL and can support patient‐centered care. LCA and LTA are powerful tools for investigating HRQOL in cancer survivors.

Implications for Practice

Long‐term colon cancer survivors show great heterogeneity in their health‐related quality of life. This study identified five distinct clusters of survivors with similar patterns of health‐related quality of life and showed that these clusters remain stable over time. It was also shown that these clusters do not significantly differ in tumor characteristics or received treatment. Cluster membership of long‐term survivors can be identified by sociodemographic characteristics but is not predetermined by diagnosis and treatment.

Health‐related quality of life is well studied, but most studies have investigated only specific aspects of quality of life despite the vast heterogeneity of adverse effects experienced. This article focuses on heterogeneity and stability in health‐related quality of life for a cohort of long‐term survivors of colon cancer.

Prospective follow-up of adult long-term survivors of allogeneic haematopoietic stem cell transplantation

BACKGROUND AND OBJECTIVE

Patients who survive beyond two years after haematopoietic stem cell transplantation (HSCT) have an increased risk of long-term complications, which impact on their survival and quality of life. The aim of this study was to design and apply a long-term follow-up protocol to detect unmet needs and treat these complications early.

PATIENTS AND METHOD

A prospective study to detect and treat complications and long-term problems within an interdisciplinary functional unit was applied to survivors beyond 2 years of allogeneic HSCT (alloHSCT).

RESULTS

Thirty-six (36%) of the 99 patients included, required intervention in a cardiovascular risk factor by health education or antihypertensive and lipid-lowering drugs. Nine of 36 (25%) patients required calcium and vitamin D intake. Low inclusion of women in gynaecological neoplasm detection protocols was detected, as well as a low adherence to dental follow-up after alloHSCT.

CONCLUSION

The follow-up of long-term survivors after alloHSCT in a multidisciplinary unit allowed unmet needs to be detected and controlled, especially in cardiovascular risk, bone metabolism, cancer prevention, and dental control.

Characterisation of long-term cancer survivors and application of statistical cure models: a protocol for an observational follow-up study in patients with colorectal cancer

BACKGROUND

Improved colorectal cancer (CRC) survival rates have been reported over the last years, with more than half of these patients surviving more than 5 years after the initial diagnosis. Better understanding these so-called long-term survivors could be very useful to further improve their prognosis as well as to detect other problems that may cause a significant deterioration in their health-related quality of life (HRQoL). Cure models provide novel statistical tools to better estimate the long-term survival rate for cancer and to identify characteristics that are differentially associated with a short or long-term prognosis. The aim of this study will be to investigate the long-term prognosis of CRC patients, characterise long-term CRC survivors and their HRQoL, and demonstrate the utility of statistical cure models to analyse survival and other associated factors in these patients.

METHODS

This is a single-centre, ambispective, observational follow-up study in a cohort of n = 1945 patients with CRC diagnosed between 2006 and 2013. A HRQoL sub-study will be performed in the survivors of a subset of n = 485 CRC patients for which baseline HRQoL data from the time of their diagnosis is already available. Information obtained from interviews and the clinical records for each patient in the cohort is already available in a computerised database from previous studies. This data includes sociodemographic characteristics, family history of cancer, comorbidities, perceived symptoms, tumour characteristics at diagnosis, type of treatment, and diagnosis and treatment delay intervals. For the follow-up, information regarding local recurrences, development of metastases, new tumours, and mortality will be updated using hospital records. The HRQoL for long-term survivors will be assessed with the EORTC QLQ-C30 and QLQ-CR29 questionnaires. An analysis of global and specific survival (competitive risk models) will be performed. Relative survival will be estimated and mixture cure models will be applied. Finally, HRQoL will be analysed through multivariate regression models.

DISCUSSION

We expect the results from this study to help us to more accurately determine the long-term survival of CRC, identify the needs and clinical situation of long-term CRC survivors, and could be used to propose new models of care for the follow-up of CRC patients.

Psilocybin-assisted group therapy for demoralized older long-term AIDS survivor men: An open-label safety and feasibility pilot study

BACKGROUND

Psilocybin therapy has shown promise as a rapid-acting treatment for depression, anxiety, and demoralization in patients with serious medical illness (e.g., cancer) when paired with individual psychotherapy. This study assessed the safety and feasibility of psilocybin-assisted group therapy for demoralization in older long-term AIDS survivor (OLTAS) men, a population with a high degree of demoralization and traumatic loss.

METHODS

Self-identified gay men OLTAS with moderate-to-severe demoralization (Demoralization Scale-II ≥8) were recruited from the community of a major US city for a single-site open-label study of psilocybin-assisted group therapy comprising 8-10 group therapy visits and one psilocybin administration visit (0·3-0·36 mg/kg po). Primary outcomes were rate and severity of adverse events, and participant recruitment and retention. The primary clinical outcome was change in mean demoralization from baseline to end-of-treatment and to 3-month follow-up assessed with a two-way repeated measures ANOVA. Trial registration: Clinicaltrials.gov (NCT02950467).

FINDINGS

From 17 July 2017 to 16 January 2019, 18 participants (mean age 59·2 years (SD 4·4)) were enrolled, administered group therapy and psilocybin, and included in intent-to-treat analyses. We detected zero serious adverse reactions and two unexpected adverse reactions to psilocybin; seven participants experienced self-limited, severe expected adverse reactions. We detected a clinically meaningful change in demoralization from baseline to 3-month follow-up (mean difference -5·78 [SD 6·01], η_p ² = 0·47, 90% CI 0·21-0·60).

INTERPRETATION

We demonstrated the feasibility, relative safety, and potential efficacy of psilocybin-assisted group therapy for demoralization in OLTAS. Groups may be an effective and efficient means of delivering psychotherapy pre- and post-psilocybin to patients with complex medical and psychiatric needs.

Fear of cancer recurrence among young adult cancer survivors-exploring long-term contributing factors in a large, population-based cohort

PURPOSE

Fear of cancer recurrence (FCR) may be debilitating, yet knowledge of FCR among the growing population of long-term young adult cancer survivors (YACS) is scarce. We explored risk of FCR and associated factors in a nation-wide, population-based cohort of YACS.

METHODS

All 5-year survivors diagnosed at the ages of 19-39 years with breast cancer (BC), malignant melanoma (MM), colorectal cancer (CRC), leukemia (LEU), or non-Hodgkin lymphoma (NHL) between 1985 and 2009 in Norway were identified by the Cancer Registry of Norway and completed the cross-sectional comprehensive NOR-CAYACS health survey. Univariate and multivariate linear regression modeling was performed.

RESULTS

In total, 936 survivors were included, with an average of 16 years since diagnoses. BC was the most prevalent cancer form (38.4%), followed by MM (24.7%), NHL (15.6%), CRC (11.8%), and LEU (9.6%). Survivors worried most about getting another cancer (74%), and (20%) reported quite a bit or a lot of FCR. BC and MM survivors had the highest FCR scores. Post-traumatic stress symptoms (PTSS) had the strongest association with FCR (Std B 0.21, p < 0.01), above demographic and clinical variables.

CONCLUSIONS

FCR is prevalent even among long-term YACS, including survivors of MM with favorable prognoses.

IMPLICATIONS FOR CANCER SURVIVORS

Attention to ongoing risks of PTSS and FCR in this growing survivor population is warranted to optimize future survivorship care.

Clinical Features in Patients With Malignant Pleural Mesothelioma With 5-Year Survival and Evaluation of Original Diagnoses

INTRODUCTION

Malignant pleural mesothelioma (MPM) is a fatal malignancy strongly associated with previous asbestos exposure. Overall survival remains dismal, partly owing to poor response to available treatment. The aims of this study were to evaluate diagnostic accuracy in a group of patients with MPM with an unusually long survival time and to assess the factors related to this prolonged survival.

MATERIALS AND METHODS

Forty-three patients with overall survival exceeding 5 years were accepted to the long-term survivor (LTS) group, and these patients were compared with 84 patients with epithelial MPM. Data were collected from various national registries and electronic medical records. In addition, all available histopathologic diagnostic samples and computed tomography studies were re-evaluated by experienced specialists.

RESULTS

Our study showed a good diagnostic accuracy, with only 1 (0.5%) patient having an incorrect MPM diagnosis. Two (0.9%) localized malignant mesotheliomas and 2 (0.9%) well-differentiated papillary mesotheliomas were also found. LTS patients were younger, more frequently female, had a better performance status at time of diagnosis, and had less evidence of prior asbestos exposure. In multivariate analysis, we showed tumor size, Eastern Cooperative Oncology Group performance status, and first-line treatment (both surgery and chemotherapy) to be associated with survival time.

CONCLUSION

We confirmed the diagnosis of MPM in an overwhelming majority of patients in the LTS group. An epithelial subtype of MPM behaving clinically more indolently seems to exist, but further tumor and genetic characterization is needed. The prolonged survival time is most likely explained by a combination of tumor-, patient-, and treatment-related factors.

Cancer-related fatigue among long-term survivors of breast, cervical, and colorectal cancer: a French registry-based controlled study

BACKGROUND

While several studies have documented fatigue during and after cancer treatment, long-term cancer survivor fatigue is underreported. In this study, we compare fatigue, quality of life (QoL), and anxiety between relapse-free cancer survivors 15 years after diagnosis and healthy controls.

METHODS

Cancer survivors (CS) were randomly selected from three large population-based cancer registries (Bas-Rhin, Calvados, and Doubs, France). Cancer-free controls were randomly selected from electoral lists with stratification on age group, residence area, and gender. All participants completed self-reported fatigue (MFI), QoL (EORTC QLQ-C30), and anxiety (STAI) questionnaires. Univariable and multivariable logistic regression were used to study the association between fatigue and cancer status, in three cancer subgroups: breast cancer (BC), cervical cancer (CC), and colorectal cancer (CRC).

RESULTS

Two hundred sixty-three CS and 688 controls (125/275, 45/153, 93/260 CS/controls for BC, CC, and CRC respectively) were included. The mean age was 66 years. In multivariable analyses, CS had higher general and mental fatigue than controls p = 0.04 and p = 0.02, respectively. No difference in QoL was observed between CS and controls. CS were more anxious than controls (p < 0.01). Anxiety was associated with general fatigue (p < 0.0001) and mental fatigue (p < 0.0001).

CONCLUSION

Fifteen years after diagnosis, cancer survivors reported more general and mental fatigue compared with controls. Our results reinforce guidelines, identifying fatigue as a persistent symptom.

Late mortality and causes of death among long-term survivors after autologous hematopoietic stem cell transplantation

By evaluating risks of late mortality and causes of death among long-term survivors after autologous hematopoietic stem cell transplantation (HSCT) in Japan, we clarified what we should focus on during follow-up to reduce them. The study cohort included 6,780 patients who had survived for ≥2 years after the first autologous HSCT performed from 1974 to 2012 for hematological diseases. With a median follow-up of 6.0 years among survivors, overall survival probabilities at 5 and 10 years after HSCT were 92% and 83%, respectively. Eight hundred thirty deaths occurred: 451, recurrent primary diseases; 87, subsequent solid cancers; 57, subsequent hematological malignancies; 55, infections; 41, respiratory diseases; 19, cardiovascular diseases; 15, liver diseases; 10, neurological diseases; and 7, kidney/genitourinary diseases (Except small numbers of other causes and missing). According to the log-rank test, the risk of overall mortality was remarkably increased among HSCT recipients compared with the that in the general Japanese population (observed/expected ratio [O/E]=5.4; 95% confidence interval [CI], 5.0-5.8). The risks of cause-specific mortality increased with infection (O/E=6.8; 95% CI, 5.1-8.8), subsequent solid cancers (O/E=1.4; 95% CI, 1.1-1.7), subsequent hematological malignancies (O/E=14.3; 95% CI, 10.8-18.5), kidney/genitourinary diseases (O/E=3.4; 95% CI, 1.4-7.1), respiratory disease (O/E=9.0; 95% CI, 6.5-1.2), and liver diseases (O/E=2.6; 95% CI, 1.4-4.2). Long-term survivors after autologous HSCT are at an increased risk of death due to secondary cancers, infections, and any organ diseases as well as recurrence compared to the general population. When monitoring these patients in the outpatient clinic, it is important for physicians to predict a change in the patient's condition and to start treatment earlier.

Predictors of survival trajectories among women with epithelial ovarian cancer

OBJECTIVE

Although ovarian cancer is a deadly disease, approximately a third of women survive ≥9 years after diagnosis. The factors associated with achieving long-term survival are not well understood. In this study, data from the Surveillance, Epidemiology, and End Results (SEER) program were used to determine predictors of survival trajectories among women with epithelial ovarian cancer and across histotype (high-grade serous carcinoma (HGSC) and non-HGSC).

METHODS

Data on 35,868 women diagnosed with epithelial ovarian cancer in 2004-2016 were extracted from SEER. Extended Cox proportional hazards regression was used to estimate overall and histotype-specific associations between patient and tumor characteristics and all-cause mortality within each survival time (t) interval (t < 3, 3 ≤ t < 6, 6 ≤ t < 9, and 9 ≤ t < 13 years).

RESULTS

Age at diagnosis, marital status, race/ethnicity, stage, and surgery were more strongly associated with mortality in the short-term survival period, and these associations waned with increasing survival time. Exceptions to this pattern were age >70 years at diagnosis, where a high risk of mortality was observed in both the t < 3 and t ≥ 9 year time periods, and non-Hispanic Asian/Pacific Islanders, where a more pronounced inverse association with mortality was observed in t ≥ 9 years after diagnosis. Similar associations were observed for HGSC, although the waning effect was not apparent for most characteristics. Mortality associations for non-HGSC were more pronounced for stage and race/ethnicity, primarily for non-Hispanic Asian/Pacific Islanders.

CONCLUSIONS

Most patient and tumor characteristics were more strongly associated with mortality in the years following diagnosis, but have declining impact with increasing survival time. Given this waning effect, it is critical to identify factors impacting risk of mortality as ovarian cancer patients advance through the survival trajectory.

Mortality patterns in long-term survivors of childhood or adolescent central nervous system tumour in Sweden

Purpose

A growing number of young patients with central nervous system (CNS) tumour survived for more than five years. However, these long-term survivors might be at risk of multiple late effects thus leading to a higher risk of late mortality. We aimed to explore the risk of late mortality and the pattern of mortality among long-term survivors of childhood or adolescent CNS tumour.

Methods

We identified 5-year survivors with childhood or adolescent CNS tumour before age 20 years through the Swedish Cancer Registry. Five controls were randomly matched for each patient to generate the reference group. We retrieved information about death via Cause of Death Register. We calculated the absolute excess risk (AER) of death and the hazard ratio (HR) of death using Cox proportional hazard model.

Results

Long-term survivors with CNS tumour suffered a significant higher risk of overall mortality (HR 6.56, 95% CI 5.71–7.53; AER 5.89, 95% CI 5.03–6.87). The mortality rate declined with the increasing survival time, but it was still higher even after 30 years of follow-up. Malignant neoplasms contributed mostly to late mortality with an AER of 3.75 (95% CI 2.95–4.75). Female survivors, survivors diagnosed at a younger age and survivors with medulloblastoma were particularly strongly associated with a higher risk of death.

Conclusions

Long-term survivors of childhood and adolescent CNS tumours are at a higher risk of late mortality, and the risk of death is affected by gender, age at diagnosis and types of CNS tumour.

Characteristics of Long-Term Survival in Patients With Myelodysplastic Syndrome Treated With 5-Azacyditine: Results From the Hellenic 5-Azacytidine Registry

BACKGROUND

Hypomethylating agents have altered the prognosis of myelodysplastic syndrome (MDS) so that long-term survival is now a feasible treatment goal.

PATIENTS AND METHODS

We analyzed data from patients with MDS treated with 5-azacytidine recorded in the Hellenic 5-azacytidine registry. We divided patients, on the basis of their survival after 5-azacytidine initiation (OS_T), in groups of long-term survivors (Q₃ and P₉₀ group with OS_T above the third quartile and the 90th percentile of the whole group, respectively) and short-term survivors comprising the remaining patients, and compared the characteristics between the groups. The study included 626 patients, 157 in the Q₃ group and 63 in the P₉₀ group.

RESULTS

Categorization per the International Prognostic Scoring System (IPSS), revised IPSS (IPSS-R), and World Health Organization-based prognostic scoring system (WPSS) was found to predict long-term survival, while multivariate analysis revealed that response to 5-azacytidine was the strongest predictor of long-term survival. Nevertheless, patients with hematologic improvement (HI) and stable disease (SD) were equally distributed in the groups of short- and long-term survival.

CONCLUSION

SD should not be considered a poor treatment response and should not be grouped with failure, while HI offers similar prognosis to SD and thus should not be grouped with complete and partial remission. Patients with SD should continue treatment with 5-azacytidine.

[Internet use after prostate cancer : Search for information and trust in disease-related information in long-term survivors]

BACKGROUND AND OBJECTIVE

The internet provides numerous sources of information about prostate cancer (PCa). The present study investigated internet use among long-term PCa survivors, trust in online PCa-related information, and associated factors.

MATERIALS AND METHODS

Based on the German national research project Familial Prostate Cancer long-term PCa survivors were asked about their internet use in 2017. Associations with sociodemographic (age at survey, children, intimate relationship, education) and disease-related parameters (time since diagnosis, PCa family history, progress) were analyzed using multivariable logistic regression.

RESULTS

In all, 4636 long-term PCa survivors were included in the analysis (mean age 76.9 years; standard deviation 6.6 years). Mean follow-up was 14.0 years. Of long-term PCa survivors, 62.1% were using the internet. Among non-users 23.5% expressed strong concerns, among users only 2.8%. Furthermore, 47.2% of internet users sought information about PCa, 18.0% of them indicated difficulties while searching for information. More than half of the users found the online information inappropriate. Lower age, shorter time since diagnosis, progress, and a more frequent internet use were associated with search for information. Only one-third fully trusted online information. Trust in online information was associated with high age, higher educational level, and frequent search for online information. Many survivors stressed that they were primarily trusting their treating urologist.

CONCLUSIONS

Two-thirds of long-term PCa survivors are using the internet. A significant proportion expressed difficulties finding proper and reliable information. Urologists should be familiar with online resources on PCa in order to offer advice to patients and to recommend adequate information on the internet.

Lifetime Transfusion Burden and Transfusion-Related Iron Overload in Adult Survivors of Solid Malignancies

BACKGROUND

Limited data exist on transfusion burden and transfusion-related iron overload in adult survivors of solid malignancies.

METHODS

Hospital-specific cancer registry data of patients with solid tumor receiving systemic anticancer treatment between January 2008 and September 2009 at the Oncology Department of the Leiden University Medical Center (The Netherlands) were retrieved and cross-referenced with red blood cell (RBC) transfusion records. Individual lifetime transfusion burden was captured in April 2015. Multitransfused long-term survivors with serum ferritin >500 μg/L were subsequently screened for hepatic and cardiac iron overload using 1.5 Tesla magnetic resonance imaging.

RESULTS

The study population consisted of 775 adult patients with solid cancer (45.2% male; median age, 58 years; >75% chemotherapy-treated), 423 (54.6%) of whom were transfused with a median of 6.0 RBC units (range 1-67). Transfusion triggers were symptomatic anemia or hemoglobin <8.1-8.9 g/dL prior to each myelosuppressive chemotherapy cycle. We identified 123 (15.9%) patients across all tumor types with a lifetime transfusion burden of ≥10 RBC units. In the absence of a hemovigilance program, none of these multitransfused patients was screened for iron overload despite a median survival of 4.6 years. In 2015 at disclosure of transfusion burden, 26 multitransfused patients were alive. Six (23.1%) had hepatic iron overload: 3.9-11.2 mg Fe/g dry weight. No cardiac iron depositions were found.

CONCLUSION

Patients with solid malignancies are at risk for multitransfusion and iron overload even when adhering to restrictive RBC transfusion policies. With improved long-term cancer survivorship, increased awareness of iatrogenic side effects of supportive therapy and development of evidence-based guidelines are essential.

IMPLICATIONS FOR PRACTICE

In the presence of a restrictive transfusion policy, ∼30% of transfused adult patients with solid cancer are multitransfused and ∼50% become long-term survivors, underscoring the need for evidence-based guidelines for the detection and management of transfusion-related iron overload in this group of patients. In each institution, a hemovigilance program should be implemented that captures the lifetime cumulative transfusion burden in all patients with cancer, irrespective of tumor type. This instrument will allow timely assessment and treatment of iron overload in cancer survivors, thus preventing organ dysfunction and decreased quality of life.

Multiple viral proteins and immune response pathways act to generate robust long-term immunity in Sudan virus survivors

Background

Profiles of immunity developed in filovirus patients and survivors have begun to shed light on antigen-specific cellular immune responses that had been previously under-studied. However, our knowledge of the breadth and length of those responses and the viral targets which mediate long-term memory immunity still lags significantly behind.

Methods

We characterized antigen-specific immune responses in whole blood samples of fifteen years post-infected survivors of the Sudan virus (SUDV) outbreak in Gulu, Uganda (2000−2001). We examined T cell and IgG responses against SUDV complete antigen and four SUDV proteins; glycoprotein (GP), nucleoprotein (NP), and viral protein 30 (VP30), and 40 (VP40).

Findings

We found survivors-maintained antigen-specific CD4+ T cell memory immune responses mediated mainly by the viral protein NP. In contrast, activated CD8+ T cell responses were nearly absent in SUDV survivors, regardless of the stimulating antigen used. Analysis of anti-viral humoral immunity revealed antigen-specific IgG antibodies against SUDV and SUDV proteins. Survivor IgGs mediated live SUDV neutralization in vitro and FcγRI and FcγRIII antibody Fc-dependent responses, mainly via antibodies to the viral proteins GP and VP40.

Interpretation

We highlight the key role of several proteins, i.e., GP, NP, and VP40, to act as mediators of distinctive and sustained cellular memory immune responses in long-term SUDV survivors. We suggest that the inclusion of these viral proteins in vaccine development may best mimic survivor native memory immune responses with the potential of protecting against viral infection.

Fatigue level changes with time in long-term Hodgkin and non-Hodgkin lymphoma survivors: a joint EORTC-LYSA cross-sectional study

BACKGROUND

Long-term lymphoma survivors often complain of persistent fatigue that remains unexplained. While largely reported in Hodgkin lymphoma (HL), long-term fatigue is poorly documented in non-Hodgkin lymphomas (NHL). Data collected in two cohort studies were used to illustrate the fatigue level changes with time in the two populations.

METHODS

Two cross-sectional studies were conducted in 2009-2010 (HL) and in 2015 (NHL) in survivors enrolled in European Organisation for Research and Treatment of Cancer (EORTC) Lymphoma Group and Lymphoma Study Association (LYSA) trials. The same protocol and questionnaires were used in both studies including the Multidimensional Fatigue Inventory (MFI) tool to assess fatigue and a checklist of health disorders. Multivariate linear regression models were used in the two populations separately to assess the influence of time since diagnosis and primary treatment, age, gender, education level, cohabitation status, obesity and health disorders on fatigue level changes. Fatigue level changes were compared to general population data.

RESULTS

Overall, data of 2023 HL and 1619 NHL survivors with fatigue assessment available (99 and 97% of cases, respectively) were analyzed. Crude levels of fatigue were similar in the two populations. Individuals who reported health disorders (61% of HL and 64% of NHL) displayed higher levels of fatigue than those who did not (P <  0.001). HL survivors showed increasing fatigue level with age while in NHL survivors mean fatigue level remained constant until age 70 and increased beyond. HL survivors showed fatigue changes with age higher than those of the general population with health disorders while NHL survivors were in between those of the general population with and without health disorders.

CONCLUSIONS

Among lymphoma survivors progressive increase of fatigue level with time since treatment completion is a distinctive feature of HL. Our data suggest that changes in fatigue level are unlikely to only depend on treatment complications and health disorders. Investigations should be undertaken to identify which factors including biologic mechanisms could explain why a substantial proportion of survivors develop high level of fatigue.

NAPOLI-1 phase 3 study of liposomal irinotecan in metastatic pancreatic cancer: Final overall survival analysis and characteristics of long-term survivors. Eur J Cancer. 2019;108:78-87. [PMID: 30654298 DOI: 10.1016/j.ejca.2018.12.007]

BACKGROUND

Liposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (5-FU/LV) is approved for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) previously treated with gemcitabine-based therapy. This approval was based on significantly improved median overall survival compared with 5-FU/LV alone (6.1 vs 4.2 months; hazard ratio [HR], 0.67) in the global phase 3 NAPOLI-1 trial. Here, we report the final survival analysis and baseline characteristics associated with long-term survivors (survival of ≥1 year) in the NAPOLI-1 trial.

PATIENTS AND METHODS

Patients with mPDAC were randomised to receive nal-IRI + 5-FU/LV (n = 117), nal-IRI (n = 151), or 5-FU/LV (n = 149) for the first 4 weeks of 6-week cycles. Baseline characteristics and efficacy in the overall population were compared with those in patients who survived ≥1 year. Through 16th November 2015, 382 overall survival events had occurred.

RESULTS

The overall survival advantage for nal-IRI+5-FU/LV vs 5-FU/LV was maintained from the original nanoliposomal irinotecan with fluorouracil and folinic acid in metastatic pancreatic cancer after previous gemcitabine-based therapy (NAPOLI-1) analysis (6.2 vs 4.2 months, respectively; HR, 0.75; 95% confidence interval: 0.57-0.99). Median progression-free survival, objective response rate and disease control rate also favoured nal-IRI+5-FU/LV therapy. Estimated one-year overall survival rates were 26% with nal-IRI+5-FU/LV and 16% with 5-FU/LV. Baseline characteristics associated with long-term survival in the nal-IRI+5-FU/LV arm were Karnofsky performance status ≥90, age ≤65 years, lower CA19-9 levels, neutrophil-to-lymphocyte ratio ≤5 and no liver metastases. No new safety concerns were detected.

CONCLUSIONS

The survival benefits of nal-IRI+5-FU/LV versus 5-FU/LV were maintained over an extended follow-up, and prognostic markers of survival ≥1 year were identified.

Long-term Adverse Effects of Acute Myeloid Leukemia Treatment on Odontogenesis in a Child

Background

Several studies showed that cancer therapies during tooth development are associated with dental abnormalities, including enamel defects, arrested tooth development, microdontic teeth, and agenesis.

Study design

We describe the case of a nine-year-old boy treated for acute myeloid leukemia at 15 months of age, who presents several dental abnormalities resulting from anticancer treatment.

Results

The patient was included and treated according to the ELAM 02 French protocol. Six years after allogenic hematopoietic stem cell transplantation, the intraoral and radiographic examination highlighted the agenesis of the second permanent molars and three of the four second premolars, microdontia of the first premolars, root stunting of the central incisors and first premolars, rootlessness of the first permanent molars, and enamel defects localized at the permanent incisors and canines. As a first step to reduce enamel defects, restorations with resin composite (Tetric EvoCeram® A2, Ivoclar Vivadent) were performed under a dental dam. Orthodontic treatment was contraindicated due to arrested tooth development, short roots, and a risk of resorption is considered too important.

Conclusion

The young age at diagnosis (<5 years of age) and intensive chemotherapy (especially myeloablative conditioning with high doses of cyclophosphamide and Busulfan) could explain the severity of the dental abnormalities. This case illustrates the importance of systematically scheduling a dental follow-up in parallel with the onco-hematologic follow-up allowing the clinicians to prevent, detect, and propose early intervention for dental late effects.

Health-related quality of life in long-term survivors of colorectal cancer and its association with all-cause mortality: a German cohort study

Background

The group of colorectal cancer (CRC) survivors continues to grow worldwide. Understanding health-related quality of life (HRQOL) determinants and consequences of HRQOL impairments in long-term CRC survivors may help to individualize survivorship care plans. We aimed to i) examine the HRQOL status of CRC long-term survivors, ii) identify cross-sectional sociodemographic and clinical correlates of HRQOL, and iii) investigate the prospective association of HRQOL after CRC diagnosis with all-cause mortality.

Methods

We assessed HRQOL within a Northern German cohort of 1294 CRC survivors at a median of 6 years after CRC diagnosis using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Cross-sectional correlates of different HRQOL dimensions were analyzed using multivariable-adjusted logistic regression models with HRQOL as a binary variable. With multivariable-adjusted Cox proportional hazards regression models, hazard ratios (HR) of all-cause mortality were estimated per 10-point-increments of an HRQOL summary score, a global quality of life scale, and HRQOL functioning and symptom domains.

Results

The median HRQOL summary score was 87 (interquartile range: 75–94). Sex, age, education, tumor location, metastases, other cancers, type of therapy, and current stoma were identified as correlates of different HRQOL scales. After a median follow-up time of 7 years after HRQOL assessment, 175 participants had died. Nearly all HRQOL domains, except for cognitive functioning and diarrhea, were significantly associated with all-cause mortality. A 10-point-increment in the summary score decreased the risk of death by 24% (HR: 0.76; 95% CI: 0.70–0.82).

Conclusions

HRQOL in CRC survivors appeared to be relatively high in the long term. Various clinical and sociodemographic factors were cross-sectionally associated with HRQOL in long-term CRC survivors. Lower HRQOL was associated with increased all-cause mortality. Individualized healthcare programs for CRC survivors (including psychosocial screening and interventions) are needed to detect decreased HRQOL and to further improve long-term HRQOL and survival.

Bone Mineral Density Corrected for Size in Childhood Leukaemia Survivors Treated with Haematopoietic Stem Cell Transplantation and Total Body Irradiation

BACKGROUND

Childhood leukaemia survivors treated with haematopoietic stem cell transplantation and total body irradiation (HSCT-TBI) have multiple risk factors for reduced bone mineral density (BMD) and growth failure; hence, BMD assessment must take body size into consideration. This study aimed to evaluate size-corrected BMD in leukaemia survivors treated with and without HSCT-TBI.

METHODS

Childhood leukaemia survivors treated with HSCT-TBI (n = 35), aged 17.3 (10.5-20.9) years, were compared with those treated with chemotherapy only, (n = 16) aged 18.5 (16.1-20.9) years, and population references. Outcome measures included anthropometric measurements and BMD by dual-energy X-ray absorptiometry. BMD was corrected for size as bone mineral apparent density (BMAD). Statistical analysis was performed by 1- and 2-sample t tests as well as regression analysis (5% significance).

RESULTS

HSCT-TBI survivors were lighter and shorter with reduced spinal heights compared with chemotherapy-only subjects and population references. Compared with population references, HSCT-TBI survivors showed lower BMD standard deviation scores (SDS) (p = 0.008), but no difference in BMAD-SDS, and chemotherapy-only survivors showed no differences in neither BMD-SDS nor BMAD-SDS. All HSCT-TBI participants with BMD-SDS <-2 had BMAD-SDS >-2. BMAD-SDS was negatively associated with age (r = -0.38, p = 0.029) in HSCT-TBI survivors.

CONCLUSIONS

Size-corrected BMD are normal in HSCT-TBI survivors in young adulthood, but may reduce overtime. BMD measurements should be corrected for size in these patients to be clinically meaningful.

Difficulties faced by long-term childhood cancer survivors: A qualitative study

PURPOSE

Due to improved survival rates of childhood cancer, there has been growing attention to survivors. In addition, experiences of illness in youth, during growth and development, affect the lives of these individuals in numerous ways. With a sample of long-term survivors of childhood cancer, this study investigated their difficult experiences after treatment completion and provided fundamental data for intervention programs that can assist growth.

METHODS

Data from 15 survivors aged 15-28 years old were collected through face-to-face interviews; analysis used Giorgi's phenomenological method.

RESULTS

The long-term survivors' lives involved a process of struggle to overcome the difficulties. Survivors had physical vestiges of cancer treatments, such as physical strength limitations, appearance changes, and sexual problems. Additionally, they experienced social withdrawal and awkwardness due to adaptation difficulties caused by social life interruption, family issues, social prejudice, and discrimination. These physical and social struggles led to experiences of mental stress and psychological withdrawal, but were followed by rebound.

CONCLUSIONS

Long-term survivors of childhood cancer experienced physical, social, and emotional struggles following treatment completion. These results can yield improved understanding of this population, facilitate attention to their challenges, and contribute to their more effective integration into society, helping them live healthy and positive lives.

Physical symptoms in long-term survivors of rare cancer

PURPOSE

Advances in cancer detection and treatment have resulted in a growing population of long-term survivors, but even years after treatment has concluded, many survivors report physical symptoms that interfere with daily living. While there are studies of late effects following common cancers, less is known about these complications in rare cancers. This study focuses on the physical symptoms reported by long-term survivors enrolled in the NIH-sponsored Rare Cancer Genetics Registry.

METHODS

The Rotterdam Symptom Checklist-Modified was administered to evaluate the severity of physical symptoms commonly reported by long-term cancer survivors. Logistic regression was used to assess association between symptoms and demographic and clinical factors.

RESULTS

In 309 subjects with a median time of 7.6 years from a diagnosis of one or more rare cancers, the median number of symptoms present per participant was 7. The most prevalent symptom reported was tiredness/lack of energy, which was present/very bothersome in 70%/25% of registrants. Women, non-whites, current smokers, and upper GI cancer survivors are particularly affected. Overall, symptom prevalence was similar across rare cancer types, time since diagnosis, and type of treatment.

CONCLUSIONS

Rare cancer survivors continue to experience troublesome symptoms many years after diagnosis, regardless of cancer type or treatment modality.

IMPLICATIONS FOR CANCER SURVIVORS

There is a need for continued emphasis on smoking cessation in cancer survivors as well as enhanced monitoring of long-term complications in female, non-white, and upper GI cancer survivors.

Determinants of illness-specific social support and its relation to distress in long-term melanoma survivors

Background

Social support is considered to be one of the most important resources for coping with cancer. However, social interactions may also be detrimental, e. g. disappointing or discouraging. The present study explored: 1. the extent of illness-specific positive aspects of social support and detrimental interactions in melanoma survivors, 2. their relationships to mental health characteristics (e. g. distress, quality of life, fatigue, coping processes, and dispositional optimism) and 3. Combinations of positive social support and detrimental interactions in relation to depression and anxiety.

Methods

Based on the cancer registry of Rhineland-Palatinate, Germany, melanoma patients diagnosed at least 5 years before the survey were contacted by their physicians. N = 689 melanoma patients filled out the Illness-specific Social Support Scale ISSS (German version) and standardised instruments measuring potential psychosocial determinants of social support.

Results

Using principal component analysis, the two factor structure of the ISSS could be reproduced with acceptable reliability; subscales were “Positive Support” (PS) and “Detrimental Interactions” (DI); Cronbach’s α = .95/.72. PS was rated higher than DI. Multivariable linear regressions identified different associations with psychosocial determinants. Survivors living in a partnership and those actively seeking out support had a higher probability of receiving PS, but not DI. PS and DI interacted regarding their association with distress: Survivors reporting high DI but low PS were the most depressed and anxious. High DI was partly buffered by PS. When DI was low, high or low PS made no difference regarding distress.

Conclusion

Psycho-oncologic interventions should take into account both positive and negative aspects of support in order to promote coping with the disease.

Dyslipidemia and lipid-lowering treatment in a hematopoietic stem cell transplant cohort: 25 years of follow-up data

BACKGROUND

Dyslipidemia is common after hematopoietic stem cell transplantation (HSCT). Few data regarding the time course of lipid profiles after HSCT, the effect of multiple transplantations, and efficacy and safety of lipid-lowering treatments are available.

OBJECTIVE

The objective of the study was to determine the prevalence and treatment of dyslipidemia over a 25-year period in a large, single-center cohort.

METHODS

One thousand one hundred ninety-six adult patients (≥16 years) who underwent HSCT during 1973 to 2013 and who survived ≥100 days were studied retrospectively.

RESULTS

The prevalence of dyslipidemia before transplantation was 36% and 28% in the autologous and allogeneic groups, respectively (P < .001). Three months after HSCT, the prevalence rose to 62% and 74% (P < .001), and at 25 years, it was 67% and 89%. Lipid profiles were similar after first and subsequent transplants. Baseline dyslipidemia (odds ratio [OR] = 2.72), allogeneic transplant (OR = 2.44), and age ≥ 35 years (OR = 2.33) were independent risk factors for dyslipidemia at 1 year. Lipid-lowering treatment was given to 223 (19%) patients, primarily in the form of statins (86%) and was associated with a decrease in total cholesterol from 246 to 192 mg/dL (P < .01) and from 244 to 195 mg/dL (P < .001) in the autologous and allogeneic groups, respectively. There were 10 cases (4%) of muscle symptoms prompting cessation of lipid-lowering therapy, including 1 case of rhabdomyolysis. The OR for dyslipidemia among patients who suffered a cardiovascular event (conditional logistic regression) was 3.5 (95% confidence interval = 1.6-7.7, P = .002).

CONCLUSION

This study confirms that dyslipidemia is a common and long-lasting phenomenon among both allogeneic and autologous HSCT patients. Statins are effective, generally well-tolerated and should be highly recommended for the management of post-HSCT dyslipidemia.

Prognostic Factors and Decision Tree for Long-Term Survival in Metastatic Uveal Melanoma

PURPOSE

The purpose of this study was to demonstrate the existence of a bimodal survival pattern in metastatic uveal melanoma. Secondary aims were to identify the characteristics and prognostic factors associated with long-term survival and to develop a clinical decision tree.

Materials and Methods

The medical records of 99 metastatic uveal melanoma patients were retrospectively reviewed. Patients were classified as either short (≤ 12 months) or long-term survivors (> 12 months) based on a graphical interpretation of the survival curve after diagnosis of the first metastatic lesion. Ophthalmic and oncological characteristicswere assessed in both groups.

RESULTS

Of the 99 patients, 62 (62.6%) were classified as short-term survivors, and 37 (37.4%) as long-term survivors. The multivariate analysis identified the following predictors of long-term survival: age ≤ 65 years (p=0.012) and unaltered serum lactate dehydrogenase levels (p=0.018); additionally, the size (smaller vs. larger) of the largest liver metastasis showed a trend towards significance (p=0.063). Based on the variables significantly associated with long-term survival, we developed a decision tree to facilitate clinical decision-making.

CONCLUSION

The findings of this study demonstrate the existence of a bimodal survival pattern in patients with metastatic uveal melanoma. The presence of certain clinical characteristics at diagnosis of distant disease is associated with long-term survival. A decision tree was developed to facilitate clinical decision-making and to counsel patients about the expected course of disease.
