Patient-centered perspectives: Examining quality-of-life integration in phase III lung cancer trials (2019-2023).

e23181 Background: In the dynamic landscape of lung cancer treatment, marked by precision medicine advancements, addressing the persistent global health challenge of lung cancer requires nuanced evaluations beyond traditional endpoints like Overall Survival (OS). Aligned with the emphasis on patient-centered care, both the US FDA and ASCO advocate for consistent integration of Quality of Life (QoL) and Patient-Reported Outcomes (PRO). The FDA's 2021 guidance underscores standardized assessment strategies, and ASCO's conceptual framework highlights the pivotal role of QoL and PRO data in elucidating the genuine value of cancer treatment options. This investigation aims to illuminate the extent to which recent trials consider patients' subjective experiences without presupposing an impact on QoL. Methods: This systematic review analyzed PubMed for Phase III lung cancer clinical trials involving anticancer drugs conducted between 2019 and 2023 to assess if QoL was included as an endpoint. Subgroup analyses categorized trials by cancer subtype (e.g., non-small cell lung cancer [NSCLC], small cell lung cancer [SCLC]). Analyses were also stratified by publication year to explore potential temporal trends. The total prevalence of QoL as an endpoint was calculated across all lung cancer subtypes for the entire 5-year period. Subanalyses included impact factor categories (≥ 10 and < 10) and differentiation between superiority and noninferiority trials. Results: The systematic analysis identified 191 Phase III lung cancer clinical trials published between 2019 and 2023, meeting the criteria. QoL was included in 31.93% of trials across all subtypes. Subgroup analyses showed that 33.72% of NSCLC trials incorporated QoL, with variations observed in early-stage resectable disease (26.31%) and unresectable advanced and metastatic cases (34.66%). For SCLC, 19.04% of trials included QoL, with none in the limited stage and 22.22% in the extensive stage. Stratified by publication year, 2019 had 33.33%, 2020 had 39.02%, 2021 had 33.33%, 2022 had 23.33%, and 2023 had 28.94% trials with QoL assessments. Stratification based on impact factor (IF) and trial type revealed 29.4% in Journals ≥10 IF, 35.6% in Journals < 10 IF, 35.5% in superiority trials, and 21.6% in non-inferiority trials. Conclusions: Our analysis reveals a significant shortfall in incorporating QoL as an endpoint. Across all subtypes and stages, a limited percentage of trials included PRO, highlighting a crucial gap in evaluating the comprehensive impact of interventions. The underrepresentation of QoL assessments signals a need for greater attention to the holistic patient experience in lung cancer research. Moving forward, a more standardized and comprehensive integration of QoL assessments in Phase III trials is essential to enhance our understanding of treatment impact and inform more patient-centered care decisions.
