Abstract
Background: Systemic therapy for metastatic renal cell cancer (mRCC) has changed significantly due to randomized controlled trial results. We investigated whether these changes affect real-world outcomes and clarified factors associated with treatment outcomes in patients from a single institution outside of clinical trials.
Methods: We retrospectively reviewed records of mRCC patients treated at Osaka International Cancer Institute between January 2005 and May 2024. Between-group analysis of progression-free survival (PFS) and overall survival (OS) by Kaplan-Meier comparison and identification of survival-associated factors by univariate and multivariate analyses were performed. Patients assumed ineligible for clinical trials were analyzed in subgroups according to any of Eastern Cooperative Oncology Group performance status > 1, hemoglobin level < 9.0 g/dL, estimated glomerular filtration rate < 40 mL/min/1.73 m2, platelet count < 100,000/μL, neutrophil count < 1500/μL, non-clear cell histology, or brain metastasis.
Results: In total, 320 patients were evaluated: 2005-2009, n = 58; 2010-2014, n = 77; 2015‒2019, n = 86; and 2020‒2024, n = 99. Significant between-group differences were observed for median PFS (7 vs. 8 vs. 12 vs. 20 months; p = 0.0048) and (35 vs. 38 vs. 67 vs. 52 months; p = 0.0206). Multivariate analysis revealed that first-line or subsequent-line immune checkpoint inhibitor (ICI) use was an independent factor for OS (HR: 0.28, p < 0.0001). Even among 112 (35%) trial-ineligible patients, multivariate analysis demonstrated that the use of first-line or subsequent-line ICI was an independent factor for OS (HR: 0.26, p < 0.0001).
Conclusion: Over time, treatment outcomes appeared to have improved with real-world treatment for mRCC, with use of ICIs being related to improvements in treatment outcomes.
期刊介绍：
The International Journal of Clinical Oncology (IJCO) welcomes original research papers on all aspects of clinical oncology that report the results of novel and timely investigations. Reports on clinical trials are encouraged. Experimental studies will also be accepted if they have obvious relevance to clinical oncology. Membership in the Japan Society of Clinical Oncology is not a prerequisite for submission to the journal. Papers are received on the understanding that: their contents have not been published in whole or in part elsewhere; that they are subject to peer review by at least two referees and the Editors, and to editorial revision of the language and contents; and that the Editors are responsible for their acceptance, rejection, and order of publication.
