Long-term functional outcomes and quality of life in adult survivors of childhood extremity sarcomas: a report from the St. Jude Lifetime Cohort Study

Associations between perceived cancer impact and measures of health behavior in survivors of childhood cancer

PURPOSE

Perceived cancer impact (PCI) is the degree to which one feels cancer has impacted one's life. It is unknown if PCI is associated with health behaviors. The aim of this study is to determine associations between PCI and health behaviors in childhood cancer survivors.

METHODS

Participants were ≥ 5-year survivors enrolled in the St. Jude Lifetime (SJLIFE) cohort. The Brief Cancer Impact (BCIA) assessed PCI across four domains (caregiving/finances, diet/exercise, social/emotional functioning, religiosity). Responses were categorized as negative, neutral, or positive impact. Smoking, risky drinking, illicit drug use, and diet quality data were obtained via self-report. Physical activity (PA) was assessed via self-report and actigraphy. Cross-sectional and longitudinal associations between PCI and health behaviors were evaluated via multivariable logistic regression.

RESULTS

A total of 3623 participants (mean age 30.4 ± 8.3 years, 49.6% female, 81.5% NH White) were included in baseline cross-sectional analysis; 1709 had a second visit 5.0 ± 1.4 years later and were included in longitudinal analysis. At baseline, the percentage of participants who endorsed cancer as having a negative impact on caregiving/finances was 37.5%, diet/exercise 30.5%, social/emotional functioning 40.6%, and religiosity 8.7%. Negative and neutral PCI across all four domains were cross-sectionally associated with all behaviors except illicit drug use. Negative and neutral PCI at the first time point across all four domains were associated with smoking, diet quality, and PA (ORs ranging from 1.35 to 2.41) in longitudinal analyses.

CONCLUSIONS

Endorsing negative or neutral PCI is associated with adverse health behaviors.

IMPLICATIONS FOR CANCER SURVIVORS

Promoting optimal health behavior should include addressing PCI.

Promoting psychological support services for parents of children with sarcoma through health-social partnership: A quality improvement project

PURPOSE

A significant portion of parents of children diagnosed with sarcoma experience excessive stress and anxiety disorder. This quality improvement project aimed to implement a psychological support service program tailored for parents of children with sarcoma and evaluate its effects.

DESIGN AND METHODS

An interprofessional team was formed through a health-social partnership to deliver comprehensive psychological support service program involving multiple cognitive-behavioral components to parents of children with sarcoma. Parents who were identified as having excessive stress and/or anxiety disorder and voluntarily agreed to participate were enrolled. Pre- and post-intervention assessments were conducted, and previously recorded data from parents of children hospitalized in the year prior to this quality improvement project were included as historical controls.

RESULTS

A total of 48 parents, including 35 mothers and 13 fathers, participated in the quality improvement project. Results showed that participants achieved greater reduction in emotional, somatic, and behavioral stress when compared with historical controls (all p < .001). Significantly lower prevalence of moderate to severe anxiety disorder was also found (4.2% vs. 85.4%, p < .001).

CONCLUSIONS

The implementation of a psychological support service program, informed by cognitive-behavioral theory and delivered through a health-social partnership, effectively alleviated multiple facets of stress and anxiety disorder in parents of children newly diagnosed with sarcoma.

PRACTICE IMPLICATIONS

Nurses can facilitate and coordinate the collaboration among interprofessional team to deliver specialized psychological support services and ensure that parents of children with sarcoma have access to these services, ultimately enhancing their psychological well-being.

Motor and sensory impairment in survivors of childhood central nervous system (CNS) tumors in the St. Jude Lifetime Cohort (SJLIFE)

BACKGROUND

Survivors of childhood central nervous system (CNS) tumors can develop motor and sensory impairment from their cancer and treatment history. We estimated the prevalence of motor and sensory impairment in survivors compared with controls through clinical assessment and identified associated treatment exposures and functional, quality of life (QOL), and social outcomes.

METHODS

Survivors of childhood CNS tumors from the St. Jude Lifetime Cohort (n = 378, median [range] age 24.0 [18.0-53.0] years, 43.4% female) ≥5 years from diagnosis and controls (n = 445, median [range] age 34.0 [18.0-70.0] years, 55.7% female) completed in-person evaluation for motor and sensory impairment using the modified Total Neuropathy Score. Impairment was graded by modified Common Terminology Criteria for Adverse Events. Multivariable models estimated associations between grade ≥2 motor/sensory impairment, individual/treatment characteristics, and secondary outcomes (function by Physical Performance Test, fitness by physiologic cost index, QOL by Medical Outcomes Survey Short Form-36 physical/mental summary scores, social attainment).

RESULTS

Grade ≥2 motor or sensory impairment was more prevalent in survivors (24.1%, 95% Confidence Interval [CI] 19.8%-29.4%) than controls (2.9%, CI 1.4-4.5%). Among survivors, in multivariable models, motor impairment was associated with vinca exposure <15 mg/m2 versus none (OR 4.38, CI 1.06-18.08) and etoposide exposure >2036 mg/m2 versus none (OR 12.61, CI 2.19-72.72). Sensory impairment was associated with older age at diagnosis (OR 1.09, CI 1.01-1.16) and craniospinal irradiation versus none (OR 4.39, CI 1.68-11.50). There were lower odds of motor/sensory impairment in survivors treated in the year 2000 or later versus before 1990 (Motor: OR 0.29, CI 0.10-0.84, Sensory: OR 0.35, CI 0.13-0.96). Motor impairment was associated with impaired physical QOL (OR 2.64, CI 1.22-5.72).

CONCLUSIONS

In survivors of childhood CNS tumors, motor and sensory impairment is prevalent by clinical assessment, especially after exposure to etoposide, vinca, or craniospinal radiation. Treating motor impairment may improve survivors' QOL.

Burden of Childhood Cancer and the Social and Economic Challenges in Adulthood: A Systematic Review and Meta-Analysis

Importance

Significant advancements in pediatric oncology have led to a continuously growing population of survivors. Although extensive research is being conducted on the short-, medium-, and long-term somatic effects, reports on psychosocial reintegration are often conflicting; therefore, there is an urgent need to synthesize the evidence to obtain the clearest understanding and the most comprehensive answer.

Objective

To provide a comprehensive review and analysis of the socioeconomic attainment of childhood cancer survivors (CCSs) compared with their unaffected peers.

Data Sources

A systematic review and meta-analysis was conducted using data obtained from a comprehensive search of MEDLINE (via PubMed), Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) databases on October 23, 2021; the search was updated until July 31, 2023.

Study Selection

Eligible articles reported on educational attainment, employment, family formation, quality of life (QoL), or health-risk behavior-related outcomes of CCSs, and compared them with their unaffected peers. Study selection was performed in duplicate by 4 blinded independent coauthors.

Data Extraction and Synthesis

Data extraction was performed in duplicate by 4 independent authors following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Outcome measures were odds ratios (ORs) and mean differences with 95% CIs; data were pooled using a random-effects model.

Results

The search identified 43 913 articles, 280 of which were eligible for analysis, reporting data on a total of 389 502 survivors. CCSs were less likely to complete higher levels of education (OR, 0.69; 95% CI, 0.40-1.18), had higher odds of health-related unemployment (OR, 2.94; 95% CI, 1.90-4.57), and showed lower rates of marriage (OR, 0.72; 95% CI, 0.63-0.84) and parenthood (OR, 0.60; 95% CI, 0.49-0.74) compared with population-based controls.

Conclusion and Relevance

Study findings suggest that CCSs face several socioeconomic difficulties; as a result, the next goal of pediatric oncology should be to minimize adverse effects, as well as to provide lifelong survivorship support aimed at maximizing social reintegration.

Muscle strength and psychometric properties of the health-related quality of life in patients with soft tissue sarcoma resection in the thigh

OBJECTIVES

The aim of this study was to evaluate the effect of STS resection in the thigh on MS and the HRQoL.

METHODS

Fourteen adults patients with STS in the thigh who underwent wide resection and limb preservation were evaluated. The patients were submitted to the Mini-Mental State Examination (MMSE). A hand-held dynamometer was used to measure the MS the flexors, adductors, abductors, and extensors muscles of the operated and non-operated thighs and between the dominant and non-dominant operated sides. The Musculoskeletal Tumor Society (MSTS) and Short Form Health Survey-36 (SF-36) questionnaires were applied to quantify the psychometric properties of the HRQoL. The data were submitted to statistical analysis using the Wilcoxon test (MS), and Mann-Whitney and Spearman correlation (MSTS and SF-36) (α = 0.05).

RESULTS

There was no significant difference in MS between the operated side and the non-operated side, and between the dominant and non-dominant operated side (ρ > 0.05). The MSTS presented a significant difference in the emotional acceptance for patients submitted to radiotherapy (ρ = 0.029). The SF-36 showed significant differences in the emotional aspect for patients submitted to chemotherapy (ρ = 0.027) and in the social aspect between the dominant and non-dominant operated side (ρ = 0.024).

CONCLUSIONS

The HRQoL of adult patients is hampered after the treatment of STS even when MS is maintained.

Cancer-Related Worry as a Predictor of 5-yr Physical Activity Level in Childhood Cancer Survivors

PURPOSE

Cancer-related worry (CRW; concerns related to cancer and its late effects) is prevalent among childhood cancer survivors. Elevated CRW has been associated with self-reported suboptimal physical activity. The aim of this investigation was to describe associations between CRW and objectively assessed physical activity in childhood cancer survivors.

METHODS

CRW was assessed at a baseline evaluation using six survey items. Weekly minutes of moderate and vigorous physical activity were captured by actigraphy 5.25 (3.8-8.0) yr later. Factor analysis was used to identify types of worry; multiple regression determined independent associations between CRW and moderate and vigorous physical activity adjusting for sex, race, diagnosis, age at baseline, anxiety level at baseline, self-reported physical activity at baseline, and pain interference at baseline.

RESULTS

Participants ( n = 1223) were an average of 30.9 (SD, 6.9) yr at baseline and 36.1 (SD, 7.1) yr at follow-up. Thirty-seven percent were survivors of leukemia, 26% of non-CNS solid tumors, 19% of lymphoma, 11% of CNS tumors, and 6% of other malignancies. Two types of CRW were identified: "body-focused" and "general fear." Body-focused CRW ( β = -19.6, P = 0.012), endorsing pain interference ( β = -27.7, P = 0.002) at baseline, and having a diagnosis of CNS tumor ( β = -41.3, P = 0.0003) or non-CNS solid tumor ( β = -19.4, P = 0.02) were negatively associated with physical activity at follow-up.

CONCLUSIONS

CRW related to bodily function and appearance is associated with decreased physical activity. Clinicians should consider the potential negative impact of CRW on physical activity levels and provide behavioral counseling.

Early postoperative gain in activity levels of lower extremity sarcoma survivors positively affects long-term physical activity and performance

PURPOSE

Little is known about the effect of sports activity levels on health-related quality of life (HRQOL) in long-term survivors of lower-extremity sarcoma.

METHODS

Eighty-three long-term survivors of bone and soft tissue sarcoma of the lower extremities with a median follow-up of 14 (range: 5-35) years completed the University of California and Los Angeles (UCLA) activity scores before tumor resection, 1 year after surgery and at the latest follow-up, as well as a Short Form 36 (SF-36) health survey at the latest follow-up. Simple linear regression models as well as stepwise variable selection with Akaike information criterion (AIC) were undertaken.

RESULTS

The preoperative UCLA activity level (median: 9, range: 2-10) dropped to a median of 4 (range: 1-10) 1 year after surgery before increasing to a score of 6 (range: 2-10) 5 years after surgery. The long-term SF-36 physical health component summary score (PCS) was 49 (SD: 9), and the mental health component summary score (MCS) was 54 (SD: 7). A linear model with stepwise variable selection identified a negative correlation of PCS with age at surgery (estimate: -0.2; p = 0.02), UCLA score at the last follow-up (estimate: 1.4; p = 0.02) and UCLA score 1 year after surgery (estimate: 1.0; p = 0.02).

CONCLUSION

As not only the final activity levels but also the status immediately after surgery affect the PCS, higher early activity levels should be a goal of modern rehabilitation after sarcoma treatment. Further studies are needed to weigh the potential postoperative risks of higher sport activity levels against the benefits described in this study.

Skeletal Muscle Measurements in Pediatric Hematology and Oncology: Essential Components to a Comprehensive Assessment

Children with hematologic and oncologic health conditions are at risk of impaired skeletal muscle strength, size, and neuromuscular activation that may limit gross motor performance. A comprehensive assessment of neuromuscular function of these children is essential to identify the trajectory of changes in skeletal muscle and to prescribe therapeutic exercise and monitor its impact. Therefore, this review aims to (a) define fundamental properties of skeletal muscle; (b) highlight methods to quantify muscle strength, size, and neuromuscular activation; (c) describe mechanisms that contribute to muscle strength and gross motor performance in children; (d) recommend clinical assessment measures; and (e) illustrate comprehensive muscle assessment in children using examples of sickle cell disease and musculoskeletal sarcoma.

Quantifying muscle strength, size, and neuromuscular activation in adolescent and young adult survivors of musculoskeletal sarcoma: Identifying correlates and responses to functional strengthening

BACKGROUND

Medical and surgical treatment for musculoskeletal sarcoma (MSS) place survivors at risk for impairments in muscle properties including muscle strength, muscle size, and neuromuscular activation. The purpose of this study was to explore muscle properties, gross motor performance, and quality of life (QoL) and the changes in response to a 6-week functional strengthening intervention (PT-STRONG) in MSS survivors of childhood cancer (CCS).

METHODS

Eight lower extremity MSS CCS (13-23 years old) performed baseline testing and three completed PT-STRONG. Participants completed measurements of knee extension strength using handheld dynamometry, vastus lateralis (VL) and rectus femoris (RF) muscle thickness using ultrasonography at rest, and neuromuscular activation using electromyography during strength testing and a step-up task. Participants also completed gross motor and QoL assessments.

RESULTS

Compared with the non-surgical limb, MSS CCS had lower surgical limb knee extension strength, VL muscle thickness, and RF step-up muscle rate of activation (RoA). Compared with normative values, MSS CCS had decreased bilateral knee extension strength, gross motor performance, and physical QoL. Positive correlations among muscle strength, muscle thickness, and gross motor performance were identified. After PT-STRONG, MSS CCS had improvements in VL muscle thickness, VL and RF RoA duing step-up, gross motor performance, and physical QoL.

CONCLUSIONS

Positive association between larger muscle thickness with greater knee extension strength, and higher knee extension strength with better gross motor performance indicate that comprehensive physical therapy assessment and interventions that identify and target impairments in muscle properties to guide clinical decision making should be considered for MSS CCS into survivorship.

Therapeutic exercise interventions in pediatric survivors of brain cancer and other solid tumors: A scoping review

Background

Improved survival rates for children with solid tumors presents an ongoing challenge of how to maximize quality of survivorship and effectively manage the short- and long-term complications of disease and treatment. To gain an understanding of the extent and nature of research pertaining to therapeutic exercise interventions and identify knowledge gaps, we conducted a scoping review of exercise training studies conducted in pediatric survivors of brain cancer and other solid tumors.

Method

A systematic literature search was performed across four electronic databases. Papers were selected for full-text review if they included participants treated for brain cancer or other solid tumors, with at least 50% of participants aged ≤ 21 years, evaluated an exercise intervention ≥2-weeks in duration, and were published in an English, peer-reviewed journal. We included the following quantitative study designs; randomized controlled trials, non-randomized trials, and single-arm pre-test-post-test.

Results

Of the 7,482 citations identified, 17 papers met the inclusion criteria (presenting findings from eleven studies). Two studies were randomized controlled trials, five studies were non-randomized controlled trials, and four studies were a single-arm pre-test post-test design. Average age of participants ranged from 7.3-15.5 years, and time since diagnosis ranged from 3 to 70 months. Five studies included participants with brain tumors exclusively, three studies included other solid tumors, and three studies included a mixed sample (brain and other solid tumors). A wide range of exercise modalities were employed, including cycle ergometry, resistance training, sport, yoga, and active gaming. The length of the exercise program ranged from 3-40 weeks and frequency from 3-11 sessions per week. Exercise session duration ranged from 15-180 min, with most studies reporting 30-90-min sessions. Adherence ranged from 77 to 100%, with none of the studies reporting adverse events. Studies reported improvements in cardiorespiratory fitness, functional strength, physical activity, and quality of life.

Conclusions

A small number of mostly low methodological quality studies have examined the effects of therapeutic exercise in pediatric survivors of solid tumors. Although limited, the extant literature supports the feasibility and safety of therapeutic exercise interventions for pediatric survivors of brain cancer and other solid tumors.

Recommendations for the surveillance of education and employment outcomes in survivors of childhood, adolescent, and young adult cancer: A report from the International Late Effects of Childhood Cancer Guideline Harmonization Group

Educational achievement and employment outcomes are critical indicators of quality of life in survivors of childhood, adolescent, and young adult (CAYA) cancer. This review is aimed at providing an evidence-based clinical practice guideline (CPG) with internationally harmonized recommendations for the surveillance of education and employment outcomes in survivors of CAYA cancer diagnosed before the age of 30 years. The CPG was developed by a multidisciplinary panel under the umbrella of the International Late Effects of Childhood Cancer Guideline Harmonization Group. After evaluating concordances and discordances of 4 existing CPGs, the authors performed a systematic literature search through February 2021. They screened articles for eligibility, assessed quality, and extracted and summarized the data from included articles. The authors formulated recommendations based on the evidence and clinical judgment. There were 3930 articles identified, and 83 of them, originating from 17 countries, were included. On a group level, survivors were more likely to have lower educational achievement and more likely to be unemployed than comparisons. Key risk factors for poor outcomes included receiving a primary diagnosis of a central nervous system tumor and experiencing late effects. The authors recommend that health care providers be aware of the risk of educational and employment problems, implement regular surveillance, and refer survivors to specialists if problems are identified. In conclusion, this review presents a harmonized CPG that aims to facilitate evidence-based care, positively influence education and employment outcomes, and ultimately minimize the burden of disease and treatment-related late adverse effects for survivors of CAYA cancers. LAY SUMMARY: A multidisciplinary panel has developed guidelines for the surveillance of education and employment outcomes among survivors of childhood, adolescent, and young adult cancer. On the basis of evidence showing that survivors are at risk for lower educational achievement and unemployment, it is recommended that all survivors receive regular screening for educational and employment outcomes.

Seizures' impact on cognition and quality of life in childhood cancer survivors

BACKGROUND

The objective of this study was to determine the impact of seizure-related factors on neurocognitive, health-related quality of life (HRQOL), and social outcomes in survivors of childhood cancer.

METHODS

Survivors of childhood cancer treated at St. Jude Children's Hospital (n = 2022; 48.3% female; median age, 31.5 years; median time since diagnosis, 23.6 years) completed neurocognitive testing and questionnaires. The presence, severity, resolution, and treatment history of seizures were abstracted from medical records. Adjusting for the age at diagnosis, sex, and prior cancer therapy, multivariable models examined the impact of seizures on neurocognitive and HRQOL outcomes. Mediation analyses were conducted for social outcomes.

RESULTS

Seizures were identified in 232 survivors (11.5%; 29.9% of survivors with central nervous system [CNS] tumors and 9.0% of those without CNS tumors). In CNS tumor survivors, seizures were associated with poorer executive function and processing speed (P < .02); in non-CNS tumor survivors, seizures were associated with worse function in every domain (P < .05). Among non-CNS survivors, seizure severity was associated with worse processing speed (P = .023), and resolution was associated with better executive function (P = .028) and attention (P = .044). In CNS survivors, seizure resolution was associated with improved attention (P = .047) and memory (P < .02). Mediation analysis revealed that the impact of seizures on social outcomes was mediated by neurocognitive function.

CONCLUSIONS

Seizures in cancer survivors adversely affect long-term functional and psychosocial outcomes independently of cancer therapy. The resolution of seizure occurrence is associated with better outcomes. Seizure severity is associated with poorer outcomes and should be a focus of clinical management and patient education.

Long-term Follow-up Care for Childhood, Adolescent, and Young Adult Cancer Survivors

Progress in therapy has made survival into adulthood a reality for most children, adolescents, and young adults with a cancer diagnosis today. Notably, this growing population remains vulnerable to a variety of long-term therapy-related sequelae. Systematic ongoing follow-up of these patients is, therefore, important to provide for early detection of and intervention for potentially serious late-onset complications. In addition, health counseling and promotion of healthy lifestyles are important aspects of long-term follow-up care to promote risk reduction for physical and emotional health problems that commonly present during adulthood. Both general and subspecialty health care providers are playing an increasingly important role in the ongoing care of childhood cancer survivors, beyond the routine preventive care, health supervision, and anticipatory guidance provided to all patients. This report is based on the guidelines that have been developed by the Children's Oncology Group to facilitate comprehensive long-term follow-up of childhood, adolescent, and young adult cancer survivors (www.survivorshipguidelines.org).

The need for improved patient reported outcome measures in patients with extremity sarcoma: A narrative review

BACKGROUND

Extremity sarcoma causes impairments to functionality and quality of life. Patient-reported outcome measures (PROMS) assess patient perspectives relating to domains of health and quality of life.

METHODS

To describe PROMs utilised in extremity sarcoma, the available literature was screened for studies that utilised PROMs to evaluate outcomes in extremity sarcoma following surgery.

RESULTS

Seventy articles met eligibility criteria; six PROMs were identified. The Toronto Extremity Salvage Score, The Short-Form 36, The EORTC QLQ-C30, The Disabilities of the Arm, Shoulder and Hand questionnaire, the Reintegration to Normal Living index and the Patient-Reported Outcomes Measurement Information System. Most sarcoma patients score well in these tools, with bone sarcoma, and extent of resection being predictors of poor outcomes.

CONCLUSION

TESS is the only sarcoma-specific PROM, and though a valid assessment of functionality, it has difficulty differentiating patients with minor functional impairments. The absence of a disease-specific measure of health is concerning, as generic tools do not account for the unique experiences sarcoma patients face and may impair their accuracy in analysing intervention effectiveness.

Skeletal Muscle and Childhood Cancer: Where are we now and where we go from here

Skeletal muscle (muscle) is essential for physical health and for metabolic integrity, with sarcopenia (progressive muscle mass loss and weakness), a pre-curser of aging and chronic disease. Loss of lean mass and muscle quality (force generation per unit of muscle) in the general population are associated with fatigue, weakness, and slowed walking speed, eventually interfering with the ability to maintain physical independence, and impacting participation in social roles and quality of life. Muscle mass and strength impairments are also documented during childhood cancer treatment, which often persist into adult survivorship, and contribute to an aging phenotype in this vulnerable population. Although several treatment exposures appear to confer increased risk for loss of mass and strength that persists after therapy, the pathophysiology responsible for poor muscle quantity and quality is not well understood in the childhood cancer survivor population. This is partly due to limited access to both pediatric and adult survivor muscle tissue samples, and to difficulties surrounding non-invasive investigative approaches for muscle assessment. Because muscle accounts for just under half of the body's mass, and is essential for movement, metabolism and metabolic health, understanding mechanisms of injury responsible for both initial and persistent dysfunction is important, and will provide a foundation for intervention. The purpose of this review is to provide an overview of the available evidence describing associations between childhood cancer, its treatment, and muscle outcomes, identifying gaps in current knowledge.

Ewing Sarcoma-Diagnosis, Treatment, Clinical Challenges and Future Perspectives

Ewing sarcoma, a highly aggressive bone and soft-tissue cancer, is considered a prime example of the paradigms of a translocation-positive sarcoma: a genetically rather simple disease with a specific and neomorphic-potential therapeutic target, whose oncogenic role was irrefutably defined decades ago. This is a disease that by definition has micrometastatic disease at diagnosis and a dismal prognosis for patients with macrometastatic or recurrent disease. International collaborations have defined the current standard of care in prospective studies, delivering multiple cycles of systemic therapy combined with local treatment; both are associated with significant morbidity that may result in strong psychological and physical burden for survivors. Nevertheless, the combination of non-directed chemotherapeutics and ever-evolving local modalities nowadays achieve a realistic chance of cure for the majority of patients with Ewing sarcoma. In this review, we focus on the current standard of diagnosis and treatment while attempting to answer some of the most pressing questions in clinical practice. In addition, this review provides scientific answers to clinical phenomena and occasionally defines the resulting translational studies needed to overcome the hurdle of treatment-associated morbidities and, most importantly, non-survival.

The Phospholipid Research Center: Current Research in Phospholipids and Their Use in Drug Delivery

This review summarizes the research on phospholipids and their use for drug delivery related to the Phospholipid Research Center Heidelberg (PRC). The focus is on projects that have been approved by the PRC since 2017 and are currently still ongoing or have recently been completed. The different projects cover all facets of phospholipid research, from basic to applied research, including the use of phospholipids in different administration forms such as liposomes, mixed micelles, emulsions, and extrudates, up to industrial application-oriented research. These projects also include all routes of administration, namely parenteral, oral, and topical. With this review we would like to highlight possible future research directions, including a short introduction into the world of phospholipids.

Association of Exercise Intolerance With Emotional Distress, Attainment of Social Roles, and Health-Related Quality of Life Among Adult Survivors of Childhood Cancer

Importance

Exercise intolerance is associated with increased risk for morbidity and mortality in childhood cancer survivors. However, an association between exercise intolerance and psychosocial outcomes has not been fully explored.

Objective

To examine the associations between exercise intolerance and emotional distress, attainment of social roles, and health-related quality of life in childhood cancer survivors.

Design, Setting, and Participants

A cross-sectional study including 1041 adult survivors of childhood cancer and 286 community controls in the St Jude Lifetime Cohort was conducted at St Jude Children's Research Hospital. The study was performed from April 1, 2012, to March 15, 2020.

Exposures

Exercise intolerance was defined as relative peak oxygen uptake less than 85% of age- and sex-estimated levels from maximal cardiopulmonary exercise testing.

Main Outcomes and Measures

Emotional distress was measured with the 18-item Brief Symptom Inventory-18, which includes overall Global Severity Index and depression, anxiety, and somatization subscales. Participants with T scores greater than or equal to 63 were classified as having elevated levels of distress. Social attainment was evaluated using patient-reported educational, employment, and marital status. Health-related quality of life was examined with the Medical Outcomes Survey Short Form-36. Participants with T scores less than or equal to 40 were classified as reporting poor health-related quality of life.

Results

Of the 1041 participants, 528 were women (50.7%). The prevalence of exercise intolerance among survivors (mean [SD] age, 35.5 [9.2] years) was higher than that among controls (age, 34.5 [10.0] years) (survivors: 634 [60.9%] vs controls: 75 [26.2%], P < .001). After adjusting for age at diagnosis and cardiopulmonary exercise testing, sex, race/ethnicity, smoking, physical activity, and exercise intolerance were associated with an increased risk for anxiety (prevalence rate ratio [PRR], 1.95; 95% CI, 1.20-3.16), somatization (PRR, 1.86; 95% CI, 1.23-2.80), and unemployment (PRR, 1.76; 95% CI, 1.23-2.52); an inverse association was noted with having a college degree (PRR, 0.67; 95% CI, 0.50-0.88). Exercise intolerance was associated with an increased the risk for scoring less than or equal to 40 on the physical component summary of the Medical Outcomes Survey Short Form-36 (PRR, 3.69; 95% CI, 2.34-5.84). These associations persisted when either cancer treatment exposures or chronic health conditions were added to the model.

Conclusions and Relevance

The findings of this study suggest that exercise intolerance is independently associated with emotional distress, attainment of social roles, and health-related quality of life of long-term survivors of childhood cancer. The results also suggest that improving physiologic capacity may benefit general health and wellness, as well as emotional health, ability to participate in social roles, and health-related quality of life.

Cumulative Burden of Chronic Health Conditions in Adult Survivors of Osteosarcoma and Ewing Sarcoma: A Report from the St. Jude Lifetime Cohort Study

BACKGROUND

Adult survivors of childhood osteosarcoma and Ewing sarcoma are at risk of developing therapy-related chronic health conditions. We characterized the cumulative burden of chronic conditions and health status of survivors of childhood bone sarcomas.

METHODS

Survivors (n = 207) treated between 1964 and 2002 underwent comprehensive clinical assessments (history/physical examination, laboratory analysis, and physical and neurocognitive testing) and were compared with community controls (n = 272). Health conditions were defined and graded according to a modified version of the NCI's Common Terminology Criteria for Adverse Events and the cumulative burden estimated.

RESULTS

Osteosarcoma and Ewing sarcoma survivors [median age 13.6 years at diagnosis (range 1.7-24.8); age at evaluation 36.6 years (20.7-66.4)] demonstrated an increased prevalence of cardiomyopathy (14.5%; P < 0.005) compared with controls. Nearly 30% of osteosarcoma survivors had evidence of hypertension. By age 35 years, osteosarcoma and Ewing sarcoma survivors had, on average, 12.0 (95% confidence interval, 10.2-14.2) and 10.6 (8.9-12.6) grade 1-4 conditions and 4.0 (3.2-5.1) and 3.5 (2.7-4.5) grade 3-4 conditions, respectively, compared with controls [3.3 (2.9-3.7) grade 1-4 and 0.9 (0.7-1.0) grade 3-4]. Both survivor cohorts exhibited impaired 6-minute walk test, walking efficiency, mobility, strength, and endurance (P < 0.0001). Accumulation of ≥4 grade 3-4 chronic conditions was associated with deficits in executive function [RR: osteosarcoma 1.6 (1.0-2.4), P = 0.049; Ewing sarcoma 2.0 (1.2-3.3), P = 0.01] and attention [RR: osteosarcoma 2.3 (1.2-4.2); P = 0.008].

CONCLUSIONS

Survivors of osteosarcoma and Ewing sarcoma experience a high cumulative burden of chronic health conditions, with impairments of physical function and neurocognition.

IMPACT

Early intervention strategies may ameliorate the risk of comorbidities in bone sarcoma survivors.

The impact of arm lymphedema on healthcare utilization during long-term breast cancer survivorship: a population-based cohort study

PURPOSE

Cancer treatment-related late effects degrade survivors' quality of life, independence, and societal integration, yet may be ameliorated, or even reversed, with effective care. Unfortunately, survivors inconsistently receive this care and the impact on their healthcare utilization is unknown. We sought to estimate differences in utilization between breast cancer (BC) survivors with and without upper extremity lymphedema; a common, remediable late effect.

METHODS

We conducted a population-based, retrospective longitudinal cohort study of survivors with incident BC diagnosed from January 1, 1990, through December 31, 2010. HC utilization was characterized using the Berenson-Eggers Type of Service (BETOS) categories. Outcomes included overall healthcare utilization as well as its compartmentalization into the BETOS categories of (1) Evaluation and management, (2) Procedures, (3) Imaging, (4) Tests, (5) Durable medical equipment, (6) Physical/occupational therapy, (7) Other, and (8) Exceptions/Unclassified.

RESULTS

The cohort included 1906 subjects of which 94% (1800) had records meeting the inclusion criteria. Mean follow-up per survivor was 12.8 years (mean, 11, range 1-25 years). Analysis revealed that (1) survivors with BC-associated lymphedema used > 30% more services annually; (2) their increased utilization lessened but persisted for at least 10 years after diagnosis; and (3) this finding of increased utilization extends across all BETOS categories, is further amplified as BMI increases, and cannot be explained solely by lymphedema-directed care.

CONCLUSIONS

BC-related lymphedema appears to be an important driver of survivors' healthcare utilization and guideline-concordant activities to reduce its incidence and severity may be cost neutral or saving.

IMPLICATIONS FOR CANCER SURVIVORS

Early detection and effective management of cancer-related late effects like lymphedema may reduce survivors' healthcare needs in the decades that follow their cancer treatment.

Health-related quality Of Life n patients with advanced Soft TIssue sarcomas treated with Chemotherapy (The HOLISTIC study): protocol for an international observational cohort study

INTRODUCTION

Chemotherapy is the mainstay of treatment for patients with advanced soft tissue sarcomas (STS). Treatment intent is usually palliative, aiming to improve symptoms, stabilise or reduce tumour burden and extend life. Clinical trials have traditionally used radiological response, time to progression and survival as measures of treatment efficacy. Health-related quality of life (HRQoL) is at least equally important or more important than survival for many patients with advanced cancer. Systematically collecting HRQoL data during chemotherapy can provide greater insight into treatment efficacy from the patient perspective.The primary aims of this study are to evaluate HRQoL in patients with advanced STS treated with chemotherapy over time, explore the decision-making process and patient reflection post-treatment.

METHODS AND ANALYSIS

This is an observational, international cohort study for 132 patients aged ≥18 years with advanced STS treated at eight centres (three in the UK, five in the Netherlands). Patients will be recruited prior to starting first-line or third-line chemotherapy and invited to complete questionnaires using the Patient-Reported Outcomes Following Initial treatment and Long-term Evaluation of Survivorship registry (PROFILES); an established international registry for collection of cancer patient-reported outcomes. Online (or paper) questionnaires will be completed at baseline, each cycle of chemotherapy and 2-3 monthly during follow-up. The questionnaire package includes the Decisional Conflict Scale, Control Preferences Scale, Quality-Quantity Questionnaire, treatment expectations, European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30), EORTC financial toxicity items, Work Ability Index, Functional Assessment of Cancer Therapy-General (FACT-G) items and Decisional Regret Scale. Clinical data will be extracted from patient records and linked with questionnaire responses. The primary outcome measure is the change in global HRQoL from baseline to after cycle 4 of first-line chemotherapy (based on published data showing that patients with advanced STS complete a median number of four cycles of first-line chemotherapy).

ETHICS AND DISSEMINATION

Heath Research Authority and Research Ethics Committee (REC 17/NI/0197). Results from the Health-related quality Of Life In patients with advanced Soft TIssue sarcomas treated with Chemotherapy (HOLISTIC) study will be published in peer-reviewed journals and disseminated at local, national and international conferences. We will also present our findings at any appropriate patient meetings and involve patients in study-related publications.

TRIAL REGISTRATION NUMBER

Use of a simple form to facilitate communication on long-term consequences of treatment in sarcoma survivors

Background

To report on our experience using a simple optional form to facilitate communication on late effects between the patients and the oncologists during outpatient follow-up and to detail on the spectrum of challenges reported by sarcoma survivors.

Methods

The form was presented for the patients to complete before their consultation and covered topics related to late effects and unmet needs that the patient wished to discuss with the medical personnel. Logistic regression analysis examined how the distribution of the topics varied with age, gender, diagnosis and type of treatment received.

Results

The form was manageable in a busy outpatient clinic. Of the 265 patients that received the form, 236 (89%) returned it. Patients in a palliative setting and those with other diagnosis than bone sarcoma (BS) and soft-tissue sarcoma (STS) were excluded for subsequent analyses. The final study-cohort comprised 160 patients, 54 (34%) with BS and 106 (66%) with STS. Among these, 140 (88%) had late-effect topics they wanted to discuss with their oncologist. Fatigue was raised by 39% of the patients, pain by 29% and impaired mobility by 23%. BS patients raised fatigue more often (P < 0.005) than those with STS. Patients who had undergone multimodal treatment with chemotherapy raised fatigue more frequently (P < 0.001) than those who had only undergone surgery, radiotherapy or both.

Conclusions

A simple form on the long-term consequences of sarcoma treatment achieved a high response rate, was feasible to use in an outpatient clinic and facilitated communication on these issues. Fatigue was the most frequent topic raised and it was raised significantly more often in patients who had undergone chemotherapy.

Prevalence and Predictors of Frailty in Childhood Cancer Survivors and Siblings: A Report From the Childhood Cancer Survivor Study

PURPOSE

To estimate the prevalence of frailty among childhood cancer survivors and to determine the direct and indirect effects of treatment exposures, lifestyle factors, and severe, disabling, and life-threatening chronic condition on frailty.

METHODS

Childhood cancer survivors (≥ 5 years since diagnosis), treated between 1970 and 1999 when < 21 years old (n = 10,899; mean age, 37.6 ± 9.4 years; 48% male, 86% white) and siblings were included (n = 2,097; mean age, 42.9 ± 9.4 years). Frailty was defined as ≥ 3 of the following: low lean mass, exhaustion, low energy expenditure, walking limitations, and weakness. Generalized linear models were used to evaluate direct and indirect associations between frailty and treatment exposures, sociodemographic characteristics, lifestyle factors, and chronic condition.

RESULTS

The overall prevalence of frailty among survivors was 3 times higher compared with siblings (6.4%; 95% CI, 4.1% to 8.7%; v 2.2%; 95% CI, 1.2% to 3.2%). Survivors of CNS tumors (9.5%; 95% CI, 5.2% to 13.8%) and bone tumors (8.1%; 95% CI, 5.1% to 11.1%) had the highest prevalence of frailty. Survivors exposed to cranial radiation, pelvic radiation ≥ 34 Gy, abdominal radiation > 40 Gy, cisplatin ≥ 600 mg/m², amputation, or lung surgery had increased risk for frailty. These associations were partially but not completely attenuated when sociodemographic characteristics, lifestyle factors, and chronic conditions were added to multivariable models. Cranial radiation (prevalence ratio [PR], 1.47; 95% CI, 1.20 to 1.76), pelvic radiation ≥ 34 Gy (PR, 1.46; 95% CI, 1.01 to 2.11), and lung surgery (PR, 1.75; 95% CI, 1.28 to 2.38) remained significant after sociodemographic, lifestyle, and chronic conditions were accounted for.

CONCLUSION

Childhood cancer survivors reported a higher prevalence of frailty compared with siblings. Radiation and lung surgery exposures were associated with increased risk for frailty. Interventions to prevent, delay onset, or remediate chronic disease and/or promote healthy lifestyle are needed to decrease the prevalence of frailty and preserve function in this at-risk population.

Current review of surgical management options for extremity bone sarcomas

Modern surgical management of extremity bone sarcomas is governed by limb-sparing surgery combined with adjuvant and neoadjuvant chemotherapy.

All the resection and reconstruction techniques have to achieve oncologic excision margins, with survival rates and functional results superior to amputation.

The main reconstruction techniques of bone defects resulted after resection are: modular endoprosthetic reconstruction; bone graft reconstruction; bone transport; resection arthrodesis; and rotationplasty.

Oncologic resection and modular endoprosthetic reconstruction are the generally approved surgical options adopted for the majority of cases in major specialized bone sarcoma centres.

Good basic principles, efficient multidisciplinary approach and sustained research in the field can provide a better future for the challenge posed by extremity bone sarcoma treatment.

A Critical Review of the Impact of Sarcoma on Psychosocial Wellbeing

Background

Previous reviews of outcomes in specific sarcoma populations suggest patients have poor quality of life. In most of these reviews, there is a predominant focus on physical function rather than psychosocial outcome. The aim of this review was to describe the psychosocial impact of diagnosis and treatment on patients with all types of sarcoma.

Methods

Searches were conducted through six electronic databases for publications of any study design using a validated patient-reported outcome measure reporting the psychosocial impact in this population.

Results

Eighty-two studies fulfilled the inclusion criteria. Most (65%) were assessed of being of reasonable quality. The most common aspect of psychosocial wellbeing measured was quality of life (80%). Due to the heterogeneity of methods, outcomes, and populations, it was not possible to make definitive conclusions. It seems there is an improvement in the physical aspects of quality of life over time but not in psychosocial function or mental health. There was no change in mental health scores, but patients reported an improvement in adjusting to normal life. There are no differences according to the type of surgery patients receive, and psychosocial outcomes tend to be poorer than the general population. There is no consistency in identifying the factors that predict/influence psychosocial wellbeing.

Conclusion

The published literature does not provide a clear understanding of the impact of sarcoma diagnosis and treatment on psychosocial wellbeing. Instead, the review demonstrates a need for well-designed studies in this area and a more consistent approach to the measurement of patient-reported outcomes, which include psychosocial domains. Recommendations for future research have been proposed.

Workplace experiences and turnover intention among adult survivors of childhood cancer

PURPOSE

The purpose of this study was to investigate workplace experiences and turnover intention (consideration of leaving or changing a job) and to examine factors associated with turnover intention among survivors.

METHODS

Adult survivors of childhood cancer with a history of employment (n = 289) completed measures of workplace experiences (n = 50, 18-29 years; n = 183, 30-44 years; n = 56; > 45 years of age at follow-up). Turnover intention was assessed using three items from the Job Satisfaction Scale. Responses were dichotomized as reflecting high vs. low turnover intention. Path analysis was used to estimate the influence of demographic characteristics, treatment exposures (cranial radiation therapy [CRT]), and workplace experiences on turnover intention.

RESULTS

Thirty percent of survivors reported high turnover intention (95% CL, 25 to 36%). Exposure to CRT (P = 0.003), older attained age (P < 0.001), experiencing formal workplace discrimination (P = 0.008), and having lower continuance (P < 0.001) or affective commitment (P < 0.001) were associated with high turnover intention among survivors. Informal discrimination, mediated through job satisfaction, also influenced survivors' reported intent to leave their jobs.

CONCLUSIONS

One third of adult survivors of childhood cancer report turnover intention, which is related to their cancer treatment, but more temporally proximal, workplace discrimination. Additional research is needed to understand the consequences of turnover intention among survivors.

IMPLICATIONS FOR CANCER SURVIVORS

Survivors and their health care providers should be aware of legislative policies related to workplace discrimination (e.g., American with Disabilities Act) and related implications for job turnover.

Factors influencing risk-based care of the childhood cancer survivor in the 21st century

The population of adult survivors of childhood cancer continues to grow as survival rates improve. Although it is well established that these survivors experience various complications and comorbidities related to their malignancy and treatment, this risk is modified by many factors that are not directly linked to their cancer history. Research evaluating the influence of patient-specific demographic and genetic factors, premorbid and comorbid conditions, health behaviors, and aging has identified additional risk factors that influence cancer treatment-related toxicity and possible targets for intervention in this population. Furthermore, although current long-term follow-up guidelines comprehensively address specific therapy-related risks and provide screening recommendations, the risk profile of the population continues to evolve with ongoing modification of treatment strategies and the emergence of novel therapeutics. To address the multifactorial modifiers of cancer treatment-related health risk and evolving treatment approaches, a patient-centered and risk-adapted approach to care that often requires a multidisciplinary team approach, including medical and behavioral providers, is necessary for this population.

Compulsory military service as a measure of later physical and cognitive performance in male survivors of childhood cancer

BACKGROUND

Compromised physical fitness and cognitive difficulties have been reported as late effects of cancer treatment during childhood. To assess this issue, the military rankings of cancer survivors in medical checkups at call-up, and conscripts' physical and cognitive performance during the first weeks of compulsory military education were compared to those of matched population controls without a history of cancer.

MATERIAL AND METHODS

A total of 1680 male patients born between 1960 and 1992 with a malignancy diagnosed before the age of 16 who were alive at the call-up age (18 years) were identified using the Finnish Cancer Registry, and five age, sex and place of residence matched controls for each patient using the Population Register Centre. Data on military service were gathered from Finnish Defense Forces. A conditional logistic regression analysis, the GEE-method with the cumulative logit link function, the chi-square test, the chi-square test for trend and a one-way analysis of variance were used in different analyses.

RESULTS

Cancer survivors were exempted from military service more often than the controls (p < .001). The fit-for-service frequency was highest for survivors of kidney tumors (68%) and lowest after irradiated brain tumors (19%). In service, the results of the 12-min running test were poorer than those of controls for leukemia/non-Hodgkin lymphoma (p = .03) and brain tumor (p = .01) survivors. Interestingly, the standing long-jump test was the only muscle test for which survivor groups performed worse than controls. Performance on cognitive tests only differed from controls in brain tumor survivors.

CONCLUSIONS

Exemption from service is still common under the current guidelines, but fit-for-service survivors do well in military education. These results can be used for reassuring survivors that completion of military service is possible for those fulfilling the national general guidelines for military fitness.

Unemployment Following Childhood Cancer

BACKGROUND

Childhood cancer survivors are at risk of physical and mental long-term sequelae that may interfere with their employment situation in adulthood. We updated a systematic review from 2006 and assessed unemployment in adult childhood cancer survivors compared to the general population, and its predictors.

METHODS

Systematic literature searches for articles published between February 2006 and August 2016 were performed in CINAHL, EMBASE, PubMed, PsycINFO, and SocINDEX. We extracted unemployment rates in studies with and without population controls (controlled /uncontrolled studies). Unemployment in controlled studies was evaluated using a meta-analytic approach.

RESULTS

We included 56 studies, of which 27 were controlled studies. Approximately one in six survivors was unemployed. The overall meta-analysis of controlled studies showed that survivors were more likely to be unemployed than controls (Odds Ratio [OR] = 1.48, 95% confidence interval [CI]: [1.14; 1.93]). Elevated odds were found in survivors in the US and Canada (OR = 1.86, 95% CI: [1.26; 2.75]), as well as in Europe (OR = 1.39, 95% CI: [0.97; 1.97]). Survivors of brain tumors in particular were more likely to be unemployed (OR = 4.62, 95% CI: [2.56; 8.31]). Narrative synthesis across all included studies revealed younger age at study and diagnosis, female sex, radiotherapy, and physical late effects as further predictors of unemployment.

CONCLUSION

Childhood cancer survivors are at considerable risk of unemployment in adulthood. They may benefit from psycho-social care services along the cancer trajectory to support labor market integration.

Nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) in pediatric and young adult patients: Results from a prospective study using limited-margin radiotherapy

BACKGROUND

Indications for and delivery of adjuvant therapies for pediatric nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) have been derived largely from adult studies; therefore, significant concern remains regarding radiation exposure to normal tissue. The authors report long-term treatment outcomes and toxicities for pediatric and young adult patients with high-grade NRSTS who were treated on a prospective trial using limited-margin radiotherapy.

METHODS

Sixty-two patients (ages 3-22 years) with predominantly high-grade NRSTS requiring radiation were treated on a phase 2 institutional study of conformal external-beam radiotherapy and/or brachytherapy using a 1.5-cm to 2-cm anatomically constrained margin. The estimated cumulative incidence of local failure, Gray's method estimated cumulative incidence of local failure, Kaplan-Meier method estimated survival, competing-risk regression model determined predictors of disease outcome, and toxicity was reported according to CTCAE v2.0.

RESULTS

At a median follow-up of 5.1 years (range, 0.2-10.9 years), 9 patients had experienced local failure. The 5-year overall cumulative incidence of local failure was 14.8% (95% confidence interval [CI], 7.2%-25%), and all but 1 local failure occurred outside the highest-dose irradiation volume. The 5-year Kaplan-Meier estimates for event-free and overall survival were 49.3% (95% CI, 36.3%-61.1%) and 67.9% (95% CI, 54.2%-78.3%), respectively. Multivariable analysis indicated that younger age was the only independent predictor of local recurrence (P = .004). The 5-year cumulative incidence of grade 3 or 4 late toxicity was 15% (95% CI, 7.2%-25.3%).

CONCLUSIONS

The delivery of limited-margin radiotherapy using conformal external-beam radiotherapy or brachytherapy provides a high rate of local tumor control without an increase in marginal failures and with acceptable treatment-related morbidity. Cancer 2017;123:4419-29. © 2017 American Cancer Society.

Associations between treatment, scoliosis, pulmonary function, and physical performance in long-term survivors of sarcoma

PURPOSE

Longer survival for children with sarcoma has led to the recognition of chronic health conditions related to prior therapy. We sought to study the association of sarcoma therapy with the development of scoliosis.

METHODS

We reviewed patient demographics, treatment exposures, and functional outcomes for patients surviving >10 years after treatment for sarcoma between 1964 and 2002 at our institution. The diagnosis of scoliosis was determined by imaging. Functional performance and standardized questionnaires were completed in a long-term follow-up clinic.

RESULTS

We identified 367 patients, with median age at follow-up of 33.1 years. Scoliosis was identified in 100 (27.2%) patients. Chest radiation (relative risk (RR), 1.88 (95% confidence interval (CI), 1.21-2.92), p < 0.005) and rib resection (RR, 2.64 (CI, 1.79-3.89), p < 0.0001) were associated with an increased incidence of scoliosis; thoracotomy without rib resection was not. Of 21 patients who underwent rib resection, 16 (80.8%) had the apex of scoliosis towards the surgical side. Scoliosis was associated with worse pulmonary function (RR, 1.74 (CI, 1.14-2.66), p < 0.01) and self-reported health outcomes, including functional impairment (RR, 1.60 (CI, 1.07-2.38), p < 0.05) and cancer-related pain (RR, 1.55 (CI, 1.11-2.16), p < 0.01). Interestingly, pulmonary function was not associated with performance on the 6-min walk test in this young population.

CONCLUSIONS

Children with sarcoma are at risk of developing scoliosis when treatment regimens include chest radiation or rib resection. Identification of these risk factors may allow for early intervention designed to prevent adverse long-term outcomes.

IMPLICATIONS FOR CANCER SURVIVORS

Cancer survivors at risk of developing scoliosis may benefit from monitoring of pulmonary status and early physical therapy.

Impact of marital status during diagnosis on cancer-caused specific survival in acute myeloid leukemia patients: a case-control and population-based study

Objective

This study investigated the impact of marital status on cancer-caused specific mortality among acute myeloid leukemia (AML) patients in the United States.

Methods

We used the Surveillance, Epidemiology and End Results program to identify 50,825 patients who had their clinical and follow-up information available and were diagnosed for AML between the years 1988 and 2015. The univariate and multivariable Cox regression models were used to analyze the patient data, and to minimize the group differences due to covariates between groups, a 1:1 propensity score matching was used in subsequent subgroup analysis.

Results

Our study demonstrated that married patients were less likely to die due to AML after adjusting for demographic and clinicopathological variables, than patients with variable unmarried status. Further analysis indicated that widowed, divorced and never married status correlated with poor cancer-cause specific survival than being married in almost all subgroups after being adjusted for the aforementioned variables (P<0.05). However, the difference between married and separated was not apparent. Moreover, similar survival analysis results were also observed in the 1:1 matched subgroups of marital status, but they displayed varied prognostic factors between them. The association of survival benefit with marriage in AML was consistent with the published survival benefit of conventional therapeutic approaches.

Conclusion

Overall, our study concluded that unmarried AML patients were at greater risk of cancer-specific mortality than married, and thus indicated that physicians should focus on health care strategies that target social support, in order to reduce the cancer-specific mortality in unmarried patients.

Frailty and quality of life in adult survivors of childhood cancer

INTRODUCTION

Adult survivors of childhood cancer are at risk for frailty, a state of diminished physiologic reserve, typically seen in older adults, associated with morbidity and mortality. They are also at risk for poor quality of life. This review explores potential associations between frailty and quality of life and proposes potential interventions that may prevent or remediate frail health.

AREAS COVERED AND LITERATURE SEARCH

A literature search using MEDLINE and EMBASE was undertaken using key words: childhood cancer survivors and each of the following: frailty, physical performance, emotional health, and quality of life. 796 abstracts were reviewed for relevance. Reference lists for retrieved articles were consulted for pertinent manuscripts (N=40). Recent literature (from January 2013 to November 2016) was obtained using the key words: aging and frailty and quality of life. The final reference list includes 44 documents.

EXPERT OPINION

Childhood cancer survivors are at risk for frailty and less than optimal quality of life. Poor emotional health may contribute to this association. Further research is needed to better explain these associations and to provide a foundation for the development of interventions designed to prevent and remediate frail health and suboptimal quality of life in this population.

Feasibility and functional outcomes of children and adolescents undergoing preoperative chemotherapy prior to a limb-sparing procedure or amputation

BACKGROUND

Survivors of lower extremity (LE) malignancies experience functional deficits.

PURPOSE

The purpose of this prospective clinical trial was to determine feasibility and functional outcomes of adding pre-habilitation during the 10-12 week period prior to a planned surgery to remove the tumor in children and adolescents with a LE sarcoma.

DESIGN

Pilot study.

SETTING

St. Jude Children's Research Hospital (SJCRH).

PATIENTS

Participants included 14 individuals between the ages of 8 and 20 years who were diagnosed with a LE sarcoma. Participant outcomes were compared to a control group of 35 individuals treated for osteosarcoma that obtained the same functional assessments but no pre-habilitation.

INTERVENTION

The intervention group received strengthening exercises and mobility training 3 times per week for 30-60 minutes for 10-12 weeks preoperatively.

MEASUREMENTS

Participants completed the Functional Mobility Assessment (FMA) and measures of strength and range of motion (ROM) of bilateral lower extremities (BLEs) at baseline, after 10-12 weeks of preoperative PT, and at 20-22 weeks.

RESULTS

Twelve participants completed at least 50% of their schedule pre-habilitative sessions. The intervention group scored significantly better on the FMA than the control group at weeks 20-22 (35.6 vs. 25.7, p .0267). No significant difference was found in ROM or strength.

LIMITATIONS

Due to this study being a pilot study, the sample size was small. Therefore, we cannot infer generalizability.

CONCLUSIONS

Findings suggest that those diagnosed with a LE malignancy awaiting a limb sparing procedure or amputation participate in at least 50% of scheduled PT sessions and benefit from them.
