Psychosocial aspects of quality of life outcomes in post-treatment human papillomavirus-associated cancer survivors in the United States: A scoping review

Human papillomavirus (HPV)-associated cancers (oropharyngeal, cervical, vulvar, vaginal, anorectal, and penile cancers) have previously been reported to have favorable survival outcomes making patients' quality of life (QoL) an important consideration for clinicians. This scoping review examined the literature on the post-treatment psychosocial QoL outcomes in patients HPV-associated cancers in the United States. The final set of 57 articles were comprised of patients that predominantly identified as Non-Hispanic White, females, or those with cervical or gynecologic cancers. Physical and psychological QoL were the most studied domains. Qualitative studies demonstrated salient themes including low health literacy on HPV-associated cancers, decreased sexual well-being, and increased feelings of stress and fear. Future work is needed in understanding psychosocial QoL in non-gynecologic HPV-associated cancers among individuals from underrepresented racial/ethnic groups, male patients, and those of lower socioeconomic status. Additionally, cancer-related stigma is relatively understudied among patients with HPV-associated cancers.

Global quality of life and mortality risk in patients with cancer: a systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis aimed to examine the impact of global quality of life (QOL) on mortality risk in patients with cancer, considering cancer type and timepoint of QOL assessment.

METHODS

A systematic search was conducted using Cumulated Index to Nursing and Allied Health Literature, PubMed/MEDLINE, and Scopus databases from inception to December 2022. Observational studies that assessed QOL and examined mortality risk in patients with cancer were extracted. Subgroup analyses were performed for cancer types and timepoints of QOL assessment.

RESULTS

Overall, global QOL was significantly associated with mortality risk (hazard ratio: 1.06, 95% confidence interval: 1.05-1.07; p < 0.00001). A subgroup analysis based on cancer type demonstrated that lung, head and neck, breast, esophagus, colon, prostate, hematologic, liver, gynecologic, stomach, brain, bladder, bone and soft tissue, and mixed type cancers were significantly associated with mortality risk; however, melanoma and pancreatic cancer were not significantly associated with mortality risk. Additionally, global QOL was associated with mortality risk at all timepoints (pretreatment, posttreatment, and palliative phase); pretreatment QOL had the largest impact, followed by posttreatment QOL.

CONCLUSION

These findings provide evidence that QOL is associated with mortality risk in patients with cancer at any timepoint. These results indicate the importance of evaluating the QOL and supportive interventions to improve QOL in any phase.

Choosing the right questions - A systematic review of patient reported outcome measures used in radiotherapy and proton beam therapy

The implementation of PROMs into clinical practice has been shown to improve quality of care. This systematic review aims to identify which PROMs are suitable for implementation within routine clinical practice in a radiotherapy or PBT service.The bibliographic databases MEDLINE, EMBASE and EMCARE were searched. Articles published between 1st January 2008 to 1st June 2023, that reported PROMs being utilised as an outcome measure were included. Inclusion criteria also included being written in English, involving human patients, aged 16 and above, receiving external beam radiotherapy or PBT for six defined tumour sites. PROMs identified within the included articles were subjected to quality assessment using the COSMIN reporting guidelines. Results are reported as per PRISMA guidelines. A total of 268 studies were identified in the search, of which 52 fulfilled the inclusion criteria. The use of 39 different PROMs was reported. The PROMs identified were mostly tumour or site-specific quality of life (n = 23) measures but also included generic cancer (n = 3), health-related quality-of-life (n = 6), and symptom specific (n = 7) measures.None of the PROMs identified received a high GRADE score for good content. There were 13 PROMs that received a moderate GRADE score. The remaining PROMs either had limited evidence of development and validation within the patient cohorts investigated, or lacked relevance or comprehensiveness needed for routine PROMs collection in a radiotherapy or PBT service.This review highlights that there are a wide variety of PROMs being utilised within radiotherapy research, but most lack specificity to radiotherapy side-effects. There is a risk that by using non-specific PROMs in clinical practice, patients might not receive the supportive care that they need.

Cultural and linguistic appropriateness of a web-based breastfeeding educational resource for Saudi women: Consensus development conference approach

AIM

The purpose of this study was to investigate the cultural and linguistic appropriateness of the content, images and layout of the web-based breastfeeding educational resource for Saudi women using a consensus development approach.

BACKGROUND

Although the World Health Organization highly recommends exclusive breastfeeding, there is a decline in breastfeeding rates in Saudi Arabia, especially during hospital stay. The combining of health professional support with e-technology tools has been proposed as a method to increase exclusive breastfeeding. However, the cultural and linguistic appropriateness of an e-technology-based approach has not been explored in Saudi women.

METHODS

After developing a content draft of the web-based breastfeeding educational resource specific to Saudi culture, an online consensus development conference was organised with ten participants including two university researchers and eight health care providers to investigate the cultural and linguistic appropriateness of the educational content. The participants from Saudi Arabia were Saudi mothers who had breastfeeding experiences and were key maternity health professionals employed at the Maternity and Children Hospital of Dammam, Saudi Arabia. The SQUIRE checklist was used in the reporting of this study.

RESULTS

Feedback received prior to the meeting showed that 81% of the content was acceptable and minor changes were required. Changes were made to the content based on the suggestions and feedback received. The consensus group accepted all the changes and the content was finalised.

CONCLUSIONS

The online consensus development conference was found to be a very convenient way to decide on the cultural and linguistic appropriateness of the content of the web-based breastfeeding educational resource allowing the participation of experts from different countries; this was considered a critical step in ensuring the successful implementation of the intervention.

Quality of life changes over time and predictors in a large head and neck patients' cohort: secondary analysis from an Italian multi-center longitudinal, prospective, observational study-a study of the Italian Association of Radiotherapy and Clinical Oncology (AIRO) head and neck working group

PURPOSE

The present study examined the longitudinal trajectories, through hierarchical modeling, of quality of life among patients with head and neck cancer, specifically symptoms burden, during radiotherapy, and in the follow-up period (1, 3, 6, and 12 months after completion of radiotherapy), through the M.D. Anderson Symptom Inventory Head and Neck questionnaire, formed by three factors. Furthermore, analyses were conducted controlling for socio-demographic as well as clinical characteristics.

METHODS

Multi-level mixed-effects linear regression was used to estimate the association between quality of life and time, age, gender, household, educational level, employment status, ECOG performance status, human papilloma virus (HPV) status, surgery, chemotherapy, alcohol intake, and smoking.

RESULTS

Among the 166 participants, time resulted to be a predictor of all the three questionnaire factors, namely, general and specific related symptoms and interference with daily life. Moreover, regarding symptom interference with daily activities factor, HPV-positive status played a significant role. Considering only HPV-negative patients, only time predicted patients' quality of life. Differently, among HPV-positive patients, other variables, such as gender, educational level, alcohol use, surgery, age at diagnosis, employment status, and ECOG status, resulted significant.

CONCLUSION

It was evident that quality of life of patients with head and neck cancer declined during RT, whereas it slowly improved after ending treatment. Our results clarified the role of some socio-demographic and clinical variables, for instance, HPV, which would allow to develop treatments tailored to each patient.

Comparing the M.D. Anderson Symptom and Dysphagia Inventories for Head and Neck Cancer Patients

OBJECTIVES

Where patient-reported outcome measures (PROMs) may be administered at multiple patient visits, it is advantageous to capture these symptoms with as few questions as possible. In this study, the M.D. Anderson Head and Neck Symptom Inventory (MDASI-HN), and the M.D. Anderson Dysphagia Inventory (MDADI) is compared to determine if using the MDASI-HN alone would overlook symptoms identified with MDADI.

METHODS

The MDASI-HN and the MDADI were completed by 156 patients, postradiotherapy for head and neck cancer (HNC). Associations between the two instruments were analyzed using correlation analysis, unsupervised machine learning, and sensitivity analysis.

RESULTS

Little correlation was found between the two surveys; however, there was overlap between MDASI-HN dry mouth and many MDADI items, confirming that dry mouth is an important factor in difficulty swallowing, and patient QoL. Taking longer to eat (MDADI), was the most commonly reported item overall, with 85 (54%) patients rating it as moderate-severe. Dry mouth was the most endorsed MDASI-HN item (68, 44%). There were 51 patients missed by the MDASI-HN, reporting no moderate-severe symptoms, but reported one or more moderate-severe QoL impacts on MDADI. If patients who reported a score of 2 or higher on the MDASI-HN Dry Mouth item are flagged as requiring follow-up, the number of patients missed by MDASI-HN drops to 15.

CONCLUSION

In an HNC clinic where MDASI-HN is routinely administered, assessment of symptoms and QoL might be enhanced by reducing the value at which MDASI Dry Mouth is considered moderate-severe to 2.

Reporting of tobacco use and tobacco-related analyses in cancer cooperative group clinical trials: a systematic scoping review

BACKGROUND

Continued smoking after a diagnosis of cancer negatively impacts cancer outcomes, but the impact of tobacco on newer treatments options is not well established. Collecting and evaluating tobacco use in clinical trials may advance understanding of the consequences of tobacco use on treatment modalities, but little is known about the frequency of reporting and analysis of tobacco use in cancer cooperative clinical trial groups.

PATIENTS AND METHODS

A comprehensive literature search was conducted to identify cancer cooperative group clinical trials published from January 2017-October 2019. Eligible studies evaluated either systemic and/or radiation therapies, included ≥100 adult patients, and reported on at least one of: overall survival, disease/progression-free survival, response rates, toxicities/adverse events, or quality-of-life.

RESULTS

A total of 91 studies representing 90 trials met inclusion criteria with trial start dates ranging from 1995 to 2015 with 14% involving lung and 5% head and neck cancer patients. A total of 19 studies reported baseline tobacco use; 2 reported collecting follow-up tobacco use. Seven studies reported analysis of the impact of baseline tobacco use on clinical outcomes. There was significant heterogeneity in the reporting of baseline tobacco use: 7 reported never/ever status, 10 reported never/ex-smoker/current smoker status, and 4 reported measuring smoking intensity. None reported verifying smoking status or second-hand smoke exposure. Trials of lung and head and neck cancers were more likely to report baseline tobacco use than other disease sites (83% versus 6%, P < 0.001).

CONCLUSIONS

Few cancer cooperative group clinical trials report and analyze trial participants' tobacco use. Significant heterogeneity exists in reporting tobacco use. Routine standardized collection and reporting of tobacco use at baseline and follow-up in clinical trials should be implemented to enable investigators to evaluate the impact of tobacco use on new cancer therapies.

Baseline MD Anderson Symptom Inventory Score is Strongly Associated With Patient-reported Acute and Late Toxicity Following (Chemo) Radiotherapy for Head and Neck Cancers

AIMS

Patient-reported outcomes measures (PROMs) are an increasingly recognised end point of radiotherapy studies. We hypothesised that the baseline PROMs score is the strongest predictor for acute and late scores after treatment. We assessed the strength of association of baseline MD Anderson Symptom Inventory (MDASI) scores, alongside other known factors for patient- or clinician-reported toxicity, with acute (6-week) and late (12-month) scores in head and neck cancer (HNC) patients following (chemo)radiotherapy.

MATERIALS AND METHODS

This was a retrospective analysis of longitudinal MDASI scores for 247 patients receiving (chemo)radiotherapy for HNC via multivariable linear regression. The factors investigated were: baseline symptom score, age, sex, concurrent chemotherapy, disease stage, radiotherapy fractionation, prior definitive surgery and performance status. Patients with a baseline score >4 in any item were defined as symptomatic in that category.

RESULTS

Patients rated symptomatic for an MDASI item pre-treatment on average reported statistically (P < 0.0005) and clinically (>-1.5) significant reductions in scores 6 weeks and 12 months after (chemo)radiotherapy for all considered sub-items except taste, dryness of mouth and problems with teeth. Conversely patients asymptomatic at baseline reported a worsening of scores at both time points. Other investigated factors showed little association with changes in MDASI scores following treatment.

CONCLUSIONS

Our data show that baseline MDASI scores are strongly associated with patient-reported toxicity 6 weeks and 12 months after (chemo)radiotherapy for HNC. Patients who are symptomatic at baseline can experience an early and durable benefit from treatment. This finding can inform discussions with patients before therapy and has implications for use of PROMs scores for the assessment of toxicity in randomised trials.

Quality of life score as a prognosticator for pharyngeal cancer patients treated with radiotherapy

The purpose of this study was to evaluate the prognostic value of quality of life (QOL) scores acquired not only pre-treatment, but also 1 month after treatment for locoregional control (LRC), distant metastasis-free survival (DMFS), and overall survival (OS) in patients with pharyngeal cancer treated using radiotherapy. Data for 102 patients with naso-, oro-, or hypo-pharyngeal cancer treated between December 2008 and September 2017 were retrospectively analyzed. About 90% of the patients were male. The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) was used for QOL assessments. Associations between QLQ-C30 scores before and 1 month after treatment and outcomes including LRC, DMFS, and OS were analyzed using Cox proportional hazard models. Median follow-up was 37 months (range, 5–117 months). Three-year LRC, DMFS, and OS rates were 77.8%, 60.0%, and 66.5%, respectively. Pre-treatment emotional functioning and diarrhea at 1 month after treatment were identified as significant predictors of LRC. Pre-treatment global QOL and diarrhea at 1 month after treatment were detected as significant predictors of DMFS. Pre-treatment emotional functioning, pre-treatment appetite loss, and diarrhea at 1 month after treatment were detected as significant predictors of OS. Diarrhea at 1 month after treatment was the most powerful QOL variable for predicting LRC, DMFS and OS. Our study revealed that several QOL scores not only before treatment but also 1 month after treatment correlated with LRC, DMFS and OS. In particular, the diarrhea domain of QOL at 1 month after treatment offered the most powerful prognosticator for pharyngeal cancer patients treated with radiotherapy.

A positron emission tomography radiomic signature for distant metastases risk in oropharyngeal cancer patients treated with definitive chemoradiotherapy

•

The wavelet_LHL_GLDZM_LILDE feature was found to be associated with progression-free survival.

•

A binary radiomics risk score was strongly associated with distant metastases for patients with HPV p16-negtive disease.

•

Improved risk stratification could identify high-risk patients as potential candidates for adjuvant immunotherapy.

Background and purpose

Disease recurrence and distant metastases (DM) are major concerns for oropharyngeal cancer (OPC) patients receiving definitive chemo-radiotherapy. Here, we investigated whether pre-treatment primary tumor positron emission tomography (PET) features could predict progression-free survival (PFS) or DM.

Methods and materials

Primary tumors were delineated on pre-treatment PET scans for patients treated between 2005 and 2018 using gradient-based segmentation. Radiomic image features were extracted, along with SUV metrics. Features with zero variance and strong correlation to tumor volume, stage, p16 status, age or smoking were excluded. A random forest model was used to identify features associated with PFS. Kaplan-Meier methods, Cox regression and logistic regression with receiver operating characteristics (ROC) and 5-fold cross-validated areas-under-the-curve (CV-AUCs) were used.

Results

A total of 114 patients were included. With median follow-up 40 months (range: 3–138 months), 14 patients had local recurrence, 21 had DM and 38 died. Two-year actuarial local control, distant control, PFS and overall survival was 89%, 84%, 70% and 84%, respectively. The wavelet_LHL_GLDZM_LILDE feature slightly improved PFS prediction compared to clinical features alone (CV-AUC 0.73 vs. 0.71). Age > 65 years (HR = 2.64 (95%CI: 1.36–5.2), p = 0.004) and p16-negative disease (HR = 3.38 (95%CI: 1.72–6.66), p < 0.001) were associated with poor PFS. A binary radiomic classifier strongly predicted DM with multivariable HR = 3.27 (95%CI: 1.15–9.31), p = 0.027, specifically for patients with p16-negative disease with 2-year DM-free survival 83% for low-risk vs. 38% for high-risk patients (p = 0.004).

Conclusions

A radiomics signature strongly associated with DM risk could provide a tool for improved risk stratification, potentially adding adjuvant immunotherapy for high-risk patients.

A national study of health-related quality of life in patients with cancer of the base of the tongue compared to the general population and to patients with tonsillar carcinoma

BACKGROUND

This exploratory, registry-based, cross-sectional study aimed to evaluate patients' health-related quality of life (HRQOL) in a subsite of oropharyngeal cancer: cancer of the base of the tongue (CBT).

METHODS

CBT patients, treated with curative intent, completed the EORTC QLQ-C30 and QLQ-H&N35 questionnaires 15 months after diagnosis. The HRQOL of CBT patients was compared to reference scores from the general population and to that of tonsillar carcinoma patients.

RESULTS

The 190 CBT patients scored significantly worse than members of the general population on most scales. CBT patients with human papilloma virus (HPV)-positive tumors had significantly better HRQOL on 8 of 28 scales than HPV-negative patients. Compared to 405 tonsillar carcinoma patients, CBT patients had significantly worse HRQOL on 8 of the 28 scales, the majority local head and neck related problems.

CONCLUSION

One year after treatment, CBT patients' HRQOL was significantly worse in many areas compared to that of the general population and slightly worse than that of tonsillar carcinoma patients.

Effect of continuous nursing on negative emotion and quality of life in patients with leukemia under chemotherapy

OBJECTIVE

To investigate the effect of continuous nursing on negative emotion and quality of life in patients with leukemia under chemotherapy.

METHODS

Ninety-two patients with leukemia who received chemotherapy in our department were divided into observation group (n=46) and control group (n=46) according to the random number table. The patients in the control group were treated with routine nursing. The patients in the observation group were treated with continuous nursing on the basis of routine nursing. The scores of Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA) and Quality of Life Index Scale (Spitzer) of patients on admission and one month after discharge in both groups were compared.

RESULTS

There was no significant difference in HAMD, HAMA and Spitzer scores of patients on admission between the two groups (P>0.05). After one month of discharge, the HAMD and HAMA scores of patients in both groups were decreased, while the Spitzer scores of patients in both groups were increased (all P<0.05). In addition, compared with the control group, the HAMD and HAMA scores in the observation group were lower, while the Spitzer scores and nursing satisfaction in the observation group were higher (all P<0.001). The incidence of chemotherapy-related adverse reactions in the observation group was lower than that in the control group (P<0.01).

CONCLUSION

Continuous nursing can improve the negative emotion, quality of life and nursing satisfaction in patients with leukemia under chemotherapy.

Patient-reported quality of life and symptom burden measures in human papillomavirus associated oropharyngeal cancer - A review of the literature and PRO methodology

The emergence of human papillomavirus-associated oropharyngeal cancer (HPVOPC) has resulted in an explosion of clinical research offering reduced toxicity and improved health-related quality of life (HRQL) through treatment de-escalation. At the heart of this objective are patient-reported outcomes (PROs) which aim to quantify the patient experience, usually through the measurement of HRQL or symptom burden. A number of PRO measures (PROMs) are available to HNC researchers and selection of the optimal instrument relies on a detailed understanding of their content and psychometric properties matched to the clinical endpoint of interest. As PROMs become increasingly favoured as the primary or co-primary endpoints of interest in HNC clinical trials, particularly those focussed on HPVOPC, future treatment paradigms will be determined by these measures and it is imperative that they are applied with sophistication and rigor. This review draws attention to the limitations and challenges our specialty faces in PRO application, analysis and reporting. These shortfalls typically include a reliance on statistical rather than clinically relevant differences, multiple hypothesis testing, a lack of evidence-based minimal clinically important differences for the commonly used tools, as well as variations in PROM selection. The aim of this review is to provide: (1) an overview of PRO/PROM terminology and methodology in the HNC setting; (2) to provide a summary of HRQL and symptom burden reports in the HPVOPC literature; and (3) to draw attention to the unmet research need of refining PROM development, application and interpretation to guide our treatment decisions based on what matters to patients.

Therapeutic strategies of different HPV status in Head and Neck Squamous Cell Carcinoma

Head and neck squamous cell carcinoma (HNSCC) is the 9^th most common malignant tumor in the world. Based on the etiology, HNSCC has two main subtypes: human papillomavirus (HPV) -related and HPV-unrelated. HPV-positive HNSCC is more sensitive to treatment with favorable survival. Due to the different biological behaviors, individual therapy is necessary and urgently required to deduce the therapeutic intensity of HPV-positive disease and look for a more effective and toxicity-acceptable regimen for HPV-negative disease. EGFR amplification and PI3K/AKT/mTOR pathway aberrant activation are quite common in HPV-positive HNSCC. Besides, HPV infection alters immune cell infiltrating in HNSCC and encompasses a diverse and heterogeneous landscape with more immune infiltration. On the other hand, the chance of HPV-negative cancers harboring mutation on the P53 gene is significantly higher than that of HPV-positive disease. This review focuses on the updated preclinical and clinical data of HPV-positive and HPV-negative HNSCC and discusses the therapeutic strategies of different HPV status in HNSCC.

Patient-Reported Outcomes as Independent Prognostic Factors for Survival in Oncology: Systematic Review and Meta-Analysis

OBJECTIVES

Assessment of patient-reported outcomes (PROs) in oncology is of critical importance because it provides unique information that may also predict clinical outcomes.

METHODS

We conducted a systematic review of prognostic factor studies to examine the prognostic value of PROs for survival in cancer. A systematic literature search was performed in PubMed for studies published between 2013 and 2018. We considered any study, regardless of the research design, that included at least 1 PRO domain in the final multivariable prognostic model. The protocol (EPIPHANY) was published and registered in the International Prospective Register of Systematic Reviews (CRD42018099160).

RESULTS

Eligibility criteria selected 138 studies including 158 127 patients, of which 43 studies were randomized, controlled trials. Overall, 120 (87%) studies reported at least 1 PRO to be statistically significantly prognostic for overall survival. Lung (n = 41, 29.7%) and genitourinary (n = 27, 19.6%) cancers were most commonly investigated. The prognostic value of PROs was investigated in secondary data analyses in 101 (73.2%) studies. The EORTC QLQ-C30 questionnaire was the most frequently used measure, and its physical functioning scale (range 0-100) the most frequent independent prognostic PRO, with a pooled hazard ratio estimate of 0.88 per 10-point increase (95% CI 0.84-0.92).

CONCLUSIONS

There is convincing evidence that PROs provide independent prognostic information for overall survival across cancer populations and disease stages. Further research is needed to translate current evidence-based data into prognostic tools to aid in clinical decision making.

The course of health-related quality of life from diagnosis to two years follow-up in patients with oropharyngeal cancer: does HPV status matter?

Purpose

To investigate the course of health-related quality of life (HRQOL) from diagnosis to 2 years follow-up among patients with oropharyngeal cancer (OPSCC), in relation to human papilloma virus (HPV) status.

Methods

This study included 270 OPSCC patients. Age, sex, tumor sublocation, tumor stage, HPV status, treatment modality, comorbidity, smoking, and alcohol use were retrieved from medical records. HPV status was positive when p16 and HPV DNA tests were both positive. HRQOL was assessed using the EORTC QLQ-C30/QLQ-H&N35 pretreatment and at 6 weeks, 6, 12, 18, and 24 months after treatment. To compare the course of HRQOL between patients with an HPV-positive versus HPV-negative tumor, linear and logistic mixed models were used.

Results

Patients with an HPV-positive tumor (29%) were more often male, diagnosed with a tumor of the tonsil or base of the tongue, treated with single treatment, had fewer comorbidities, were less often current smokers and had lower alcohol consumption. Adjusted for confounders, the course of global quality of life, physical, role, and social functioning, fatigue, pain, insomnia, and appetite loss was significantly different: patients with an HPV-positive tumor scored better before treatment, worsened during treatment, and recovered better and faster at follow-up, compared to patients with an HPV-negative tumor. The course of emotional functioning and oral pain was also significantly different between the two groups, but with other trajectories.

Conclusion

The course of HRQOL is different in patients with an HPV-positive tumor versus an HPV-negative tumor, adjusted for sociodemographic, clinical, and lifestyle confounders.

Hypofractionated chemoradiation for head and cancer: Data from the PET NECK trial

There has been increased interest in hypofractionated accelerated chemoradiation for head and neck cancer during the recent first peak of the COVID-19 pandemic. Prospective data regarding this approach from randomised trials is lacking. In the PET NECK study, 564 patients with squamous cell carcinoma of the head and neck receiving definitive chemoradiation were randomised to either planned neck dissection or PET CT scan guided surveillance. In this surgical trial, three radiotherapy fractionation schedules delivered over 7, 6 or 4 weeks were permitted with synchronous chemotherapy. The purpose of this study was to determine efficacy and quality of life outcomes associated with the use of these schedules. Primary local control and overall survival in addition to quality of life measures at immediately post treatment and 6, 12 and 24 months post-treatment were compared between the three fractionation cohorts. In the 525 patients where fractionation data was available, 181 (34%), 288 (55%) and 56 (11%) patients received 68-70 Gy in 34-35 fractions (#), 60-66 Gy in 30# and 55 Gy in 20# respectively. At a minimum follow up of two years following treatment there was no significant difference between the three fractionation schemes in local control, overall survival or any quality of life measure. Despite the obvious limitations of this study, some data is provided to support the use of hypofractionated accelerated chemoradiation to avoid delays in cancer treatment and reduce hospital visits during the peak of a pandemic. Data from on-going randomised trials examining hypofractionated chemoradiation may be useful for selecting fractionation schedules during future pandemics.

Prognostic value of patient-reported outcomes from international randomised clinical trials on cancer: a systematic review

A previous review published in 2008 highlighted the prognostic significance of baseline patient-reported outcomes (PROs) as independent predictors of the overall survival of patients with cancer in clinical studies. In response to the methodological limitations of studies included in the previous review, recommendations were subsequently published in the same year to promote a higher level of methodological rigour in studies of prognostic factors. Our systematic review aimed to provide an update on progress with the implementation of these recommendations and to assess whether the methodological quality of prognostic factor analyses has changed over time. Of the 44 studies published between 2006 and 2018 that were included in our review, more standardisation and rigour of the methods used for prognostic factor analysis was found compared with the previous review. 41 (93%) of the trials reported at least one PRO domain as independently prognostic. The most common significant prognostic factors reported were physical functioning (17 [39%] studies) and global health or quality of life (15 [34%] studies). These findings highlight the value of PROs as prognostic or stratification factors in research across most types of cancer.

Xerostomia-related quality of life for patients with oropharyngeal carcinoma treated with proton therapy

PURPOSE

We report longitudinal patient-reported quality-of-life (QoL) outcomes related to xerostomia in patients with oropharyngeal cancer treated with intensity-modulated proton therapy (IMPT).

MATERIALS AND METHODS

Patients treated from May 2012 through December 2016 at a single institution for AJCC7 stage III-IV, M0 oropharyngeal cancer were given the 15-item Xerostomia-Related QoL Scale (XeQoLS) before, during, and for up to 2 years after treatment. We evaluated the evolution of xerostomia-related QoL over that time, and examined potential associations between those measures with clinical characteristics.

RESULTS

Sixty-nine patients had XeQoLS scores at baseline and at least once either during or after treatment. The mean (±SD) XeQoLS score (0-4) was 0.24 ± 0.57 at baseline. Subsequent scores were 2.00 ± 1.01 at 6 weeks on treatment, and 1.03 ± 0.76, 0.97 ± 0.78, 0.82 ± 0.69, and 0.70 ± 0.75 at 10 weeks, 6 months, 1 year, and 2 years after treatment, respectively. All were statistically different from baseline (p < 0.001). Univariate analyses demonstrated associations between XeQoLS score and time (p < 0.0001 for each interval), baseline XeQoLS score (p < 0.0001), stage (p = 0.008), N status (p = 0.006), and mean oral cavity dose (p = 0.038), but not for age, sex, T status, receipt of chemotherapy, smoking history, disease site, laterality of neck irradiation, mean parotid dose, or mean submandibular dose. Multivariate analysis suggested that baseline XeQoLS scores, phase of treatment, and N status were associated with XeQoLS scores measured during treatment and recovery.

CONCLUSIONS

Patients receiving IMPT reported the greatest xerostomia-related QoL impairment at 6 weeks on treatment, with a 49% improvement by 10 weeks after treatment; however, XeQoLS scores remained above baseline after 2 years. As we aim to establish the value of IMPT in oropharyngeal tumors to de-intensify treatment over conventional therapy, these data help inform discussions about xerostomia-related quality of life for patients with oropharyngeal cancer treated with IMPT.

Regional Radiation Therapy for Oropharyngeal Cancer in the HPV Era

Oropharyngeal carcinoma associated with the human papillomavirus is increasing in incidence and represents a unique head and neck disease with favorable treatment outcomes. This review evaluates the evolving role of radiotherapy in regional management with an overall goal of treatment de-escalation in the appropriate patient. Determining the optimal approach and selection factors for treatment de-escalation is under active investigation. Response to induction chemotherapy, refining adverse pathologic factors after a primary surgical approach, decreasing radiation dose with or without chemotherapy in the definitive or adjuvant settings as well as more selective nodal level irradiation all are current strategies for treatment de-escalation. This review details the likely changes in regional radiotherapy management for oropharyngeal carcinoma in the modern human papillomavirus era and discusses future approaches to patient selection with the goal of reducing toxicities while maintaining function preservation and quality of life in group of patients who are younger and healthier than traditional head and neck cancer patients.

Performance status scale for head and neck scores for oral cancer survivors: predictors and factors for improving quality of life

OBJECTIVES

This study aimed to determine the factors associated with long-term quality of life of oral cancer survivors.

MATERIALS AND METHODS

A total of 508 survivors were assessed using the performance status scale for head and neck (PSS-HN), which comprises Eating in Public (E-Public), Normalcy of Diet (N-Diet), and Understandability of Speech (U-Speech). Stepwise multiple linear regression analysis was performed.

RESULTS

The median time between the end of treatment and participating in the survey was 38 months (range, 6-250). Overall, 57-60% of survivors achieved full performance (100 score) of each PSS-HN score, whereas 15% had moderate or severe impairment (≤ 50 score) in E-Public and N-Diet, and 4% had impairment in U-Speech. These three scores deteriorated with increasing T-stage. Age, soft tissue reconstruction, trismus, and missing occlusal contacts on the contralateral side were significantly associated with E-Public and N-Diet. Neck dissection, hard tissue reconstruction, and missing occlusal contacts bilaterally were associated with U-Speech score.

CONCLUSION

Older age, T4 tumor, and soft tissue reconstruction were predictors of low E-Public and N-Diet performance scores. Increasing mouth opening and maintaining optimal occlusal contacts on the contralateral side may be effective ways to improve N-Diet and E-Public performance. Maintaining optimal occlusal contacts bilaterally may be effective for improving speech performance.

CLINICAL RELEVANCE

Oral health care to increase optimal occlusal contacts and rehabilitation of trismus may be promising factors to improve the functional performance of oral cancer survivors.

Associations among human papillomavirus, inflammation, and fatigue in patients with head and neck cancer

BACKGROUND

Human papillomavirus (HPV) infection has contributed to an increased incidence of squamous cell carcinoma of the head and neck (SCCHN). Fatigue is a major side effect of SCCHN and its treatment. However, to the authors' knowledge, the association between HPV and fatigue has not been examined to date, nor is it known whether HPV influences biological mechanisms of fatigue, including inflammation.

METHODS

Patients with SCCHN who were without distant metastasis were assessed at baseline (pre-radiotherapy) and 1 month and 3 months postradiotherapy. Fatigue was measured using the Multidimensional Fatigue Inventory. Peripheral inflammation was assessed by plasma C-reactive protein (CRP), interleukin 1 receptor antagonist (IL-1ra), soluble tumor necrosis factor receptor 2 (sTNFR2), and IL-6. Mixed effect models were used to examine associations.

RESULTS

A total of 94 patients who were newly diagnosed were enrolled; 53% had HPV-related tumors. Patients with HPV-unrelated tumors had higher fatigue and higher plasma CRP, sTNFR2, and IL-6 over time, especially at baseline and 3 months after intensity-modulated radiotherapy compared with those with HPV-related tumors (all P < .05). However, fatigue and plasma sTNFR2 increased more significantly from baseline to 1 month after radiotherapy in the HPV-related group compared with the HPV-unrelated group (both P < .01). Controlling for significant covariates, HPV status and inflammation were found to be independent predictors of fatigue over time.

CONCLUSIONS

HPV status is an important marker of vulnerability to the behavioral and immune consequences of SCCHN and its treatment, providing support for different symptom management strategies. Special emphasis should be placed on addressing marked persistent fatigue in patients with HPV-unrelated tumors, whereas attention should be paid to the large increases in fatigue during treatment among patients with HPV-related tumors.

Early Response Assessment on Mid-treatment Computed Tomography Predicts for Locoregional Recurrence in Oropharyngeal Cancer Patients Treated With Definitive Radiation Therapy

PURPOSE

To evaluate whether a response assessment using mid-treatment computed tomography (CT) scans during definitive radiation therapy (RT) for oropharyngeal head and neck cancer can predict for locoregional recurrence (LRR).

METHODS AND MATERIALS

Head and neck cancer patients who receive RT at our institution undergo CT repeat scans at the 15th fraction, with treatment replanning in the case of an inadequate dose to gross disease or an increased dose to organs at risk. A retrospective cohort analysis was performed of 96 consecutive patients with oropharyngeal cancer treated from 2007 to 2015 with mid-treatment repeat CT scans available. The primary disease volume and involved lymph node volume were delineated on the pre- and mid-treatment CT scans. Univariable and multivariable Cox proportional hazards regression analyses were used to evaluate the efficacy of the mid-treatment reduction in tumor volume as a predictor of LRR. Risk stratification was performed by dichotomizing the patients into high- and low-risk groups according to the mid-treatment response and p16 status and smoking history.

RESULTS

With a median follow-up of 34 months, 14 patients experienced LRR. The median reduction in the total tumor volume was 18.7% (interquartile range 8.4%-30.9%). A reduction in total tumor volume greater than the median was an independent predictor of LRR (hazard ratio 0.22, 95% confidence interval 0.05-0.89; P = .020). The reduction in primary tumor volume was an even stronger predictor of LRR (hazard ratio 0.11, 95% confidence interval 0.02-0.57; P = .002). Stratifying patients into a high-risk group for those with a reduction in the total tumor volume at mid-treatment at or less than the median, p16 negative status, and smoking status of >10 pack-years and a low-risk group for those without these factors, we found a clear separation in Kaplan-Meier curves, with actuarial 3-year locoregional control, progression-free survival, and overall survival rates for the high-risk patients of 45.7%, 38.2%, and 71.8% compared with 90.7%, 70.6%, and 89.8% for low-risk patients, respectively (P ≤ .021 for all).

CONCLUSIONS

Our results have shown that the treatment response from an early assessment using mid-treatment CT scans is an independent predictor of LRR and can be used to effectively distinguish high- and low-risk patients, allowing for risk-adaptive treatment stratification at the midway point.

Patient-reported quality-of-life outcomes after de-escalated chemoradiation for human papillomavirus-positive oropharyngeal carcinoma: Findings from a phase 2 trial

BACKGROUND

The current study represents a subset analysis of quality-of-life (QOL) outcomes among patients treated on a phase 2 trial of de-escalated chemoradiation for human papillomavirus (HPV)-associated oropharyngeal cancer.

METHODS

Eligibility included newly diagnosed, (American Joint Committee on Cancer, 7th edition) stage III or IV oropharyngeal squamous cell carcinoma, p16 positivity, age ≥ 18 years, and a Zubrod performance status of 0 to 1. Treatment was induction paclitaxel at a dose of 175 mg/m² and carboplatin at an area under the curve of 6 for 2 cycles followed by response-adapted, dose-reduced radiation of 54 Gy or 60 Gy with weekly concurrent paclitaxel at a dose of 30 mg/m² . The University of Washington Quality of Life (UW-QOL) and the Functional Assessment of Cancer Therapy-Head and Neck questionnaires were used to assess patient-reported QOL as a secondary endpoint.

RESULTS

A total of 45 patients were registered, 40 of whom completed QOL surveys and were evaluable. Nadirs for overall UW-QOL and Functional Assessment of Cancer Therapy-Head and Neck scores were reached at 4 weeks after treatment but returned to baseline at 3 months. Nearly all functional indices returned to baseline levels by 6 to 9 months. The mean overall UW-QOL score was 71.6 at baseline compared with 70.8, 73.0, 83.3, and 81.1, respectively, at 3 months, 6 months, 1 year, and 2 years after therapy. The percentage of patients rating their overall QOL as "very good" or "outstanding" at 6 months, 1 year, and 2 years using the UW-QOL was 50%, 77%, and 84%, respectively.

CONCLUSIONS

This de-escalation regimen achieved QOL outcomes that were favorable compared with historical controls. These results serve as powerful evidence that ongoing de-escalation efforts lead to tangible gains in function and QOL. Cancer 2018;124:521-9. © 2017 American Cancer Society.

Quality of Life and Performance Status From a Substudy Conducted Within a Prospective Phase 3 Randomized Trial of Concurrent Accelerated Radiation Plus Cisplatin With or Without Cetuximab for Locally Advanced Head and Neck Carcinoma: NRG Oncology Radiation Therapy Oncology Group 0522

PURPOSE

To analyze the quality of life (QOL) and performance status (PS) (secondary outcome) in patients with stage III to IV head and neck cancer (HNC) enrolled on a prospective randomized phase 3 trial comparing radiation-cisplatin without cetuximab (CIS) or with cetuximab (CET/CIS). The QOL hypothesis proposed a between-arm difference in Functional Assessment of Cancer Therapy-Head and Neck (FACT-HN) total score of ≥10% of the instrument range from baseline to 1 year.

METHODS AND MATERIALS

Patients who gave consent to the QOL/PS study completed the FACT-HN, Performance Status Scale for HNC (PSS-HN), and EuroQol (EQ-5D) at baseline through to 5 years. The pretreatment QOL/PS scores were correlated with outcome and p16 status in patients with oropharyngeal cancer (OPC).

RESULTS

Of 818 analyzable patients, the 1-year change from baseline score for FACT-HN total was -0.41 (CIS arm) and -5.11 (CET/CIS arm) (P=.016), representing a 3.2% between-arm change of the FACT-HN total score. The mean EQ-5D index and PSS-HN scores were not significantly different between arms. The p16-positive OPC patients had significantly higher baseline and 1-year scores for PSS-HN, FACT-HN total, physical and functional subscales, and 2-years for the EQ-5D index compared with p16-negative OPC patients. Higher pretreatment PSS-HN diet, PSS-HN eating, FACT-HN, and EQ-5D index scores were associated with better overall survival (OS) and progression-free (PFS) survival on multivariate analysis. Higher baseline FACT-HN total, functional, physical subscale, and EQ-5D index scores were associated with improved OS and PFS in p16-positive OPC patients but not in p16-negative and non-OPC patients.

CONCLUSION

There was no clinically meaningful difference in QOL/PS between arms. The p16-positive OPC patients had significantly higher QOL/PS than did p16-negative patients. Pretreatment QOL/PS is a significant independent predictor of outcome in locally advanced HNC.
