International phase IV validation study of an EORTC quality of life questionnaire for testicular cancer patients: the EORTC QLQ-TC26

Impact of a one-year supervised physical activity program on long-term cancer-related fatigue and mediating effects of the gut microbiota in metastatic testicular cancer patients: protocol of the prospective multicentre, randomized controlled phase-III STARTER trial

BACKGROUND

Testicular germ cell tumours (TGCTs) are the most common malignancy in men aged 15-40 years, with increasing incidence worldwide. About 33 ~ 50% of the patients present with metastatic disease at diagnosis. TGCT survivors experience short- and long-term sequelae, including cancer-related fatigue (CRF). Physical activity (PA) has established effects on reducing CRF and other sequelae and improving health-related quality of life (HRQoL). However, its impact on TGCT survivors has so far received little attention. The gut microbiota plays a crucial role in various physiological functions, including cognition and metabolism, and may mediate the effects of PA on CRF and other sequelae, but this has not been investigated in randomized controlled trials.

METHODS

This national, multicentre, phase-III trial will evaluate the impact of a one-year supervised PA program on CRF and other short- and long-term sequelae in metastatic TGCT patients receiving cisplatin-based chemotherapy combined with etoposide+/-bleomycin. It will also investigate potential mediating effects of the gut microbiota and its metabolites involved in the gut-brain axis on the relationship between PA and CRF and other sequelae. A total of 236 men ≥ 18 years of age with metastatic TGCT (seminoma and non-seminoma) will be enrolled before starting first-line chemotherapy in several French hospitals. The primary (CRF) and secondary (cognitive/psychological/metabolic sequelae, HRQoL, etc.) outcomes and gut microbiota and relevant metabolites will be assessed at inclusion, during and at the end of the one-year intervention, and annually until 10 years since inclusion to assess long-term sequelae, more specifically CRF, cardiovascular toxicities, and second primary cancer occurrence in this population.

DISCUSSION

This trial will provide comprehensive and novel insights into the effects of a long-term supervised PA program on CRF and other sequelae in metastatic TGCT patients receiving first-line chemotherapy. It will also contribute to understanding the potential role of the gut microbiota and its metabolites in mediating the effects of PA on these outcomes. The findings of this study will help the development of effective PA interventions to improve the health of TGCT survivors and may have implications for other cancer populations as well.

TRIAL REGISTRATION

The study was registered on ClinicalTrials.gov (NCT05588700) on 20 Oct. 2022.

Sexual function using the EORTC QLQ-TC26 in testicular cancer survivors: A multi-institutional, cross-sectional study

OBJECTIVE

To evaluate sexual function after treatment using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Testicular Cancer 26 (EORTC QLQ-TC26) questionnaire in Japanese testicular cancer (TC) survivors in a multi-institutional, cross-sectional study.

METHODS

This study enrolled TC survivors who visited any of eight high-volume institutions in Japan from 2018 to 2019. After obtaining informed consent, participants completed the EORTC QLQ-TC26 questionnaires. We evaluated sexual function after treatment for TC using the EORTC QLQ-TC26 and analyzed the impact of treatment on sexual function in TC survivors.

RESULTS

A total of 567 TC survivors responded to the EORTC QLQ-TC26. Median age at the time of response was 43 years (interquartile range [IQR] 35-51 years), and median follow-up period after treatment was 5.2 years (IQR 2.2-10.0 years). Sexual function, particularly ejaculatory function, was significantly lower after post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) than after Surveillance or Chemotherapy groups (p < 0.05). In the PC-RPLND group, nerve-sparing procedure preserved postoperative ejaculatory function after RPLND compared with the non-nerve-sparing and offered improved ejaculatory function with time. On multivariate analysis, RPLND was a significant predictor of post-treatment ejaculatory dysfunction, particularly without nerve-sparing (odds ratio 3.0, 95% CI 1.2-7.7, p < 0.05). In addition, TC survivors with nerve-sparing RPLND had higher sexual activity than those without.

CONCLUSION

This survey of the EORTC QLQ-TC26 showed that sexual function and activity in TC survivors after RPLND was reduced in the absence of nerve-sparing techniques.

Association of financial toxicity with quality of life in testicular cancer survivors

OBJECTIVES

Most testicular cancer (TC) survivors have long-term survival. However, the association between financial toxicity (FT), which is an economic side effect of cancer treatment, and the quality of life (QOL) of TC survivors is still unclear. Thus, the impact of FT on the QOL of TC survivors was examined in a multi-institutional cross-sectional study.

METHODS

We recruited TC survivors from eight high-volume institutions in Japan between January 2018 and March 2019. A total of 562 participants completed the EORTC QLQ-C30, EORTC QLQ-TC26 and the questionnaires on demographics, including annual income. Financial difficulty in the EORTC QLQ-C30 and low income were used to assess financial distress (FD) and financial burden (FB), respectively. FT was defined as FD and FB. The QOL scores were compared, and a multivariate logistic regression analysis for FT was performed.

RESULTS

With severe FD, TC survivors had more treatment side effects, physical limitations, and anxiety concerning employment and future. The TC survivors who reported low income were worried about their jobs and the future. The QOL of the survivors with FT exhibited high impairment, except for sexual activity. In particular, the TC survivors with FT were physically limited and anxious concerning the future. The multivariate logistic regression analysis revealed that four or more chemotherapy cycles were substantial risk factors for FT (4 cycles, odds ratio (OR) = 4.17; ≥5 cycles, OR = 6.96).

CONCLUSIONS

TC survivors who received multi-cycle chemotherapy were prone to experience FT, resulting in a decline in their health-related QOL.

Outcome Measures in Cancer Rehabilitation: Pain, Function, and Symptom Assessment

Assessment of cancer rehabilitation outcome measures is integral for patient assessment, symptom screening, and advancing scientific research. In the broad field of cancer rehabilitation, outcome measures can cross-cut across many different branches of oncologic care including clinician-reported, patient-reported, and objective measures. Specific outcome measures that apply to cancer rehabilitation include those pertinent to pain, function, quality of life, fatigue, and cognition. These outcome measures, when used in cancer rehabilitation, can be utilized to evaluate the effectiveness of an intervention and to triage to the appropriate supportive care service. This review article summarizes some of the commonly used outcome measures that can be applied in the cancer rehabilitation setting to support scholarly work and patient care.

Patient-Reported Outcomes Associated with Treatments for Testicular Cancer: A Systematic Review

Background

Testicular cancer and its treatment can have major short- and long-term effects on the health-related quality of life of those affected. This systematic review aims to summarise patient-reported outcome (PRO) data concerning health-related quality of life, functional impacts and common side-effects of treatments for testicular cancer.

Methods

We systematically searched Medline OVID, CINAHL, PubMed, Embase and the Patient-Reported Outcomes Over Time In Oncology (PROMOTION) databases from inception to 25 March 2020, using "testicular cancer" and "PRO" search terms developed in conjunction with a medical librarian. Two authors screened abstracts and full-text articles for studies that reported primary PRO data related to the treatment of testicular cancer including at least 50 participants. We excluded psychosocial data as this was included in our companion review. Data were extracted by three reviewers, and quality was assessed by two reviewers using QUAL-SYST. Studies with a quality of score over 65% were included in our narrative synthesis.

Results

A total of 1831 records were identified via our database searches and 41 met inclusion criteria. Of these, 35 included participants who had chemotherapy. Twenty-eight different PRO measures were used across the 41 studies. Of the 41 studies, 29 had quality scores over 65% and were included in our narrative synthesis. We found that chemotherapy was generally associated with a higher side-effect burden than other treatments, and higher burden was associated with higher doses of chemotherapy. Hearing problems, peripheral neuropathy, and Raynaud's phenomena were particularly common side-effects. Problems with sexual functioning were associated with chemotherapy, radiotherapy and surgery.

Discussion

While many studies found that between-treatment differences resolved within the first 12 months since diagnosis, there were many long-term and dose-dependent impacts associated with chemotherapy and radiotherapy across PRO domains. Offering information about these aspects, and information about expected survival outcomes, will help inform, prepare, and empower patients to make decisions about treatment aligned with their preferences and personal situations.

Quality of life, anxiety and depression patient-reported outcome measures in testicular cancer: A systematic review

OBJECTIVES

Several patient-reported outcome measures (PROMs) are available for the assessment of quality of life (QoL), anxiety and depression for testicular cancer (TCa); however, these PROMs have uncertain validation of their psychometric properties for TCa-only cohorts. This systematic review aims to critically analyse and evaluate the psychometric properties of these QoL, anxiety and depression PROMs.

METHODS

PubMed, EMBASE and PsycInfo were searched by two independent reviewers from inception to August 2020. Evaluative studies that assessed measurement properties of PROM(s) tools used for measuring QoL, anxiety and depression in TCa patients were included. The COnsensus-based Standards for the selection of health status Measurement Instruments (COSMIN) updated criteria for good measurement properties were used in the evaluation of PROM psychometric quality. This systematic review was registered on the PROSPERO database (CRD42020160232).

RESULTS

Of 4,305 abstracts screened, a final eight full-text articles were included in this review. Five general and two TCa-specific PROMs were identified (depression, n = 1; anxiety and depression, n = 2; QoL, n = 4). All studies were incomplete in the validation of nine measurement properties and the modal methodological quality was 'indeterminate'. The European Organisation for Research and Treatment of Cancer Quality -Testicular Cancer 26 questionnaire and CAYA-T had the highest psychometric validation with three out of nine measurement properties being 'sufficient'.

CONCLUSION

This systematic review identifies a paucity of PROM-validation studies assessing anxiety, depression and QoL in TCa-only cohorts. We recommend further comprehensive and standardised psychometric validation studies of QoL, anxiety and depression PROMs in TCa-only study populations.

Late adverse effects and quality of life in survivors of testicular germ cell tumour

Currently, ~95% of patients with testicular germ cell tumour (TGCT) are cured, resulting in an increasing number of TGCT survivors. Although cured, these men face potential late adverse effects and reduced quality of life. Survivors face a twofold increased risk of second malignant neoplasms after chemotherapy and radiotherapy, with evidence of dose-dependent associations. For survivors managed with surveillance or treated with radiotherapy, the risk of cardiovascular disease (CVD) is comparable to the risk in the general population, whereas treatment with chemotherapy increases the risk of life-threatening CVD, especially during treatment and after 10 years of follow-up. Other adverse effects are organ-related toxicities such as neuropathy and ototoxicity. Pulmonary and renal impairment in patients with TGCT treated with chemotherapy is limited. Survivors of TGCT might experience psychosocial distress including anxiety disorders, fear of cancer recurrence and TGCT-specific issues, such as sexual dysfunction. Late adverse effects can be avoided in most patients with stage I disease if followed on a surveillance programme. However, patients with disseminated disease can experience toxicities associated with radiotherapy and chemotherapy, and/or adverse effects related to surgery for residual disease. The severity of adverse effects increases with dose of both chemotherapy and radiotherapy. This Review discusses the most recent data concerning the late adverse effects of today's standard treatments for TGCT.

Health-Related Quality of Life in Testicular Cancer Survivors in Japan: A Multi-Institutional, Cross-Sectional Study Using the EORTC QLQ-TC26

OBJECTIVE

To evaluate the health-related quality of life (QOL) of testicular cancer (TC) survivors using the Japanese version of the EORTC QLQ-TC26 questionnaire in a multi-institutional, cross-sectional study.

METHODS

This study recruited TC survivors who were followed after treatment for TC at eight high-volume institutions between January, 2018 and March, 2019. The participants completed the EORTC QLQ-TC26 questionnaire and mailed the completed questionnaires to a central institution. The QOL scores were assessed according to therapeutic modality (watchful waiting, WW; chemotherapy, CT; and CT followed by retroperitoneal lymph node dissection, CT+RPLND) and follow-up period and compared using analysis of variance and Student's t-test.

RESULTS

A total of 567 TC survivors responded to the questionnaire. The median age at response was 43 years (IQR 35-51 years), and the median follow-up was 5.2 years (IQR 2.2-10.0 years). As for treatment side effects and physical limitations, the scores of the CT+RPLND group were significantly higher than those of the WW group, especially within one year after treatment. In addition, TC survivors in the CT+RPLND group reported high impairment related to job and education problems and future perspective less than 5 years after treatment. Even TC survivors in the WW group were anxious about job and education issues within one year after treatment.

CONCLUSION

TC survivors were anxious about not only cancer recurrence, but also their jobs and education. TC patients should be given appropriate information on QOL after treatment for TC to attenuate post-treatment anxiety and improve their health-related QOL.

Assessing Health-Related Quality of Life Among Survivors of Testicular Cancer: A Systematic Review

This study aimed to determine if the current health-related quality of life (HRQoL) tools created for survivors of testicular cancer are collecting the highest quality of data via a two-step methodological critique of both the seminal studies that produced a survivor of testicular cancer HRQoL tool (Phase 1) and the actual tool itself (Phase 2). It is the goal of this current article to present and discuss Phase 1.

A systematic review aimed to assess the methodological quality of studies conducted to create instruments used to measure survivors of testicular cancer HRQoL. Five reviewers independently assessed each study with the 20-item Appraisal Tool for Cross-Sectional Studies (AXIS). Inter-rater agreement and Fleiss’ kappa was also assessed to ensure consistency in reported scores. Assessments for the EORTC QLQ-TC 26 and CAYA-T studies were low (AXIS 52.5%; IRA 95%; κ = 0.779) and fair (AXIS 65%; IRA 80%; κ = 0.599), respectively. Critical appraisal of the scales included issues within the three core AXIS domains. Primary concerns related to sampling methodology and the lack of a qualitative component of their core conceptual development phase.

Both reviewed seminal studies have significant methodological concerns that question the tools’ quality. Next steps include extensive appraisal of the psychometric properties of the EORTC QLQ TC-26 and the CAYA-T to complete the comprehensive review. Accurate and reliable data are necessary to understand survivor of testicular cancer HRQoL and assist in building the bridge of communication between health care professionals and survivors to help to improve patient outcomes.

Integration of Patient Reported Outcomes in Drug Development in Genitourinary Cancers

PURPOSE OF REVIEW

Patient reported outcomes (PROs) are increasingly utilized in cancer drug development, and are of particular importance in genitourinary cancers due to symptom burden, multiple treatment options with similar efficacy, and often prolonged duration of disease. Here we review current data and perspectives related to use of PROs in drug development for genitourinary cancers, including insights on the regulatory process for drug approval.

RECENT FINDINGS

The FDA is committed to incorporating PRO data into the regulatory process for development and approval of new cancer drugs, but challenges exist due to lack of standardization of PRO instrument choice and analytic approach, missing data, and difficulty isolating treatment effect from disease-related effects. We review guidance for standardization of PRO methodology that is nonetheless tailored to disease state and anticipated effects of treatment. PRO and efficacy data should be simultaneously analyzed and reported for best clinical practice. Multiple disease-specific PRO instruments exist for genitourinary cancers. While clinicians, researchers, and regulatory bodies alike recognize the importance of PROs in cancer drug development, challenges remain regarding implementation of best practices.
