ASCO GU 2024: Development of a Patient-Centered HRQOL Measure for Metastatic RCC: A Three-Phase Study

(UroToday.com) The 2024 GU ASCO annual meeting featured a renal cell carcinoma session and a presentation by Dr. Cristiane Bergerot discussing development of a patient-centered health-related quality of life measure for metastatic renal cell carcinoma. Patients with metastatic RCC require a tailored health-related quality of life assessment.


Previous research explored FKSI-19, EORTC QLQ-C30, and EQ-5D item relevance.1-2 The pivotal first-line kidney cancer trials have assessed health related quality of life using multiple tools and different analyses, however, this has generated a plethora of exploratory results that can be challenging to interpret:kidney cancer trial table
Furthermore, some of the tools we are using go back 30 years when our current treatments did not exist:kidney cancer trials through time
As such, Dr. Bergerot and colleagues aimed to develop a tailored health-related quality of life measure for patients with metastatic RCC through a three-phase approach involving patient engagement, expert input, and advocacy.

In Phase 1, 117 patients with metastatic RCC (83:34 male: female, median age 64 years) from the US, Europe, and Brazil participated in a survey study to assess the relevance of items from established measures (FKSI-19, EORTC QLQ-C30, EQ-5D). In this cohort, 88% of patients had clear cell histology, and 35%, 30%, and 19% received immunotherapy alone, targeted therapy alone, or combination therapy, respectively:

Questions identified as relevant (based on ≥66% consensus) were selected for inclusion in a preliminary survey. Phase 2 involved assembling a panel of 11 experts who rigorously reviewed and refined survey questions. In Phase 3, the preliminary version were presented to 8 patient advocates (5:3 female: male; 6:2 patients: caregivers) to ensure alignment with patients' needs and experiences.

In Phase 1, among 54 questions, 15/54 (27%) were deemed relevant:kidney cancer qol survey
Patients requested the inclusion of a question about social/family issues and better coverage of emotional symptoms. A 12-item questionnaire was created, and the expert committee (phase 2) refined three items to incorporate patient suggestions and added one item related to functional status:expert panel kidney cancer qol study
This questionnaire included one cancer-specific item, three cancer or treatment-specific items, three non-specific emotional items, and four non-specific physical items:phase 2 quality categories
Patient advocates (phase 3) provided feedback, agreeing with the items excluded from previous questionnaires and those included. They suggested minor edits to item wording:reworded items
Dr. Bergerot concluded her presentation discussing development of a patient-centered health-related quality of life measure for metastatic renal cell carcinoma with the following take-home points:

  • Quality of life areas of priority were identified for patients with kidney cancer receiving treatment
  • Some questions appear less relevant, which push comparative analysis toward the null hypothesis
  • This study created a new model using a multidisciplinary team, which may be more relevant
  • Validation of this new model is now required
  • The final model in advanced disease will be validated in upcoming trials:
    • Retrospective analysis: PRISM study
    • Primary assessment of health related quality of life: CARE-1 study
  • Dr. Bergerot notes that her group is inviting groups with available quality of life data to collaborate in order to test and validate the model
