Overcoming Organizational Challenges of Integrating Patient-Reported Outcomes in Oncology Clinical Trials

Health-related quality of life in men with oligometastatic prostate cancer following metastases-directed stereotactic body radiotherapy: Real-world data from the E2-RADIatE OligoCare cohort

Objective

To evaluate the impact of metastases-directed stereotactic body radiotherapy (SBRT) on health-related quality of life (HRQoL) in men with oligometastatic prostate cancer (PCa) using real-world data from the OligoCare cohort.

Materials and methods

OligoCare is a pragmatic, observational cohort designed to assess the impact of metastases-directed SBRT on patients with oligometastatic disease (OMD). We report an interim analyses of the secondary endpoint HRQoL, assessed using the EORTC QLQ-C30, within six months of metastases-directed SBRT for oligometastatic disease in men with PCa among the first 1600 registered patients. HRQoL data collection was optional within the OligoCare cohort. To compare HRQoL between baseline and first follow-up assessment, a Wilcoxon signed-rank test was used. A multiple linear regression model was used to explore the HRQoL associations with predefined factors.

Results

Out of the 1600 registered patients, 658 were treated for oligometastatic PCa, of which 233 had baseline QoL data and 132 patients had both baseline and follow-up HRQoL data. At baseline, most patients had a WHO performance status of 0 or 1 (87 %), were de-novo oligometastatic (79 %), had one metastasis (90 %), and had a good overall global health status (mean 80.81, SD16.11, IQR 75-92). 51 % received hormonal therapy as concomitant systemic treatment. Patients with comorbidities as assessed by the Charlson Comorbidity index had a worse global health status at baseline (-4.88, 95 % CI:-9.35, -0.42). No clinically meaningful significant difference in global health status was observed at first assessment following SBRT (median 3.0 months) compared with baseline (mean difference 2.27, 95 % CI:-1.54, 6.08). Upon evaluating the proportions, meaningful clinically important differences (a 10-point or more difference) was observed in, 17 % and 11 % of the patients reporting deterioration and improvement of global health status, respectively.

Conclusion

Metastases-directed stereotactic body radiotherapy had no negative impact on global HRQoL within the first six months after treatment.

Health-Related Quality of Life Data in Cancer Clinical Trials for Drug Registration: The Value Beyond Reimbursement

PURPOSE

A review of the literature was performed to evaluate how quality of life measures are collected, analyzed, and reported in cancer clinical trials intended to support drug registration.Health-related quality of life (HRQoL) data points are one of the patient-reported outcome (PRO) assessments used in clinical trials to evaluate the effects of treatments from the patient perspective. The use of PROs has gained focus in cancer clinical trials as more options become available for greater longevity of patients on treatment. Standardization of PRO data is evolving and involves unique challenges when used for assessing biologic and chemotherapeutic agents for the treatment of cancer.

METHODS

In this study, a review of literature published between 2009 and 2019 was conducted using PubMed, COCHRANE Library, and Medline. The research focus was on the current guidance, implementation, and reporting as well as highlighting the issues, and recommendations for the inclusion of HRQoL end points in cancer clinical trials intended for use in drug registration.

RESULTS

Although there exist many levels of guidance for HRQoL measures in cancer drug trials, challenges to operational implementation, the current inconsistent adherence to reporting standards, and the lack of consensus and understanding of analyses limit the value and potential of the resulting data collected.

CONCLUSION

The results of HRQoL data collected from cancer clinical trials can be difficult to interpret and apply to inform clinical decision making. Increased reporting and access to these data can provide opportunities for potential applications to improve translatability of HRQoL data collected in clinical trials into practice.

Patient-Reported Outcomes in Health Economic Decision-Making: A Changing Landscape in Oncology

Cancer causes significant death and disability globally. However, costs of more personalized cancer care continue to climb, while access to basic cancer screening and treatment is not available to much of the world. This chapter provides an overview of the status of patient-reported outcomes (PROs) in cancer clinical care and research. PROs are valuable for health care and health economic decision-making at institutional, regional, national, and international levels. PRO data should be considered along with cost and survival data when approving new therapies. PRO data can also be helpful when assessing existing treatment options for patients, particularly for drugs with minor outcome and toxicity differences. Finally, PROs can be useful in reimbursement algorithms to ensure delivery of quality cancer care in value-based financing environments. The authors advocate for reframing the concept of health value, aligning PRO measures with societal values, and broadening the definition of society to extend beyond national boundaries.
