Overall survival was similar among patients enrolled in clinical trials for metastatic renal cell carcinoma (mRCC) across different geographic regions, according to a pooled retrospective analysis.

Demographic characteristics, clinicopathologic variables, survival, and toxicity data were collected across five geographic regions, including, United States/Canada (USC), Western Europe (WE), Eastern Europe (EE), Latin America (LA), and Asia/Africa/Oceania (AAO) for 4,736 patients who had mRCC treated between 2003 and 2013 and were enrolled in phase 2 and phase 3 clinical trials.

Patients in USC and WE were slightly older (mean ages, 60.6 and 60.5 years, respectively) and with higher numbers undergoing prior nephrectomy. Higher BMI was also observed in patients in the USC and LA regions. While ECOG performance status of 0 was more frequent in LA patients, treatment-related adverse events and use of statin and angiotensin inhibitor system was higher in USC.

“We highlight that, despite different baseline characteristics, OS was similar among patients enrolled in clinical trials across different geographic regions,” reported Andre P. Fay, MD , PhD, and colleagues from Dana Farber Cancer Institute, Boston, in Journal of Global Oncology . “Access to clinical trials may be an important alternative to eliminate health disparities and promote health equity in patients with mRCC.”

This study was supported by Pfizer and in part by the Dana-Farber/Harvard Cancer Center Kidney SPORE, DF/HCC Kidney Cancer Program, and the Trust Family, Loker Pinard, and Michael Brigham Funds for Kidney Cancer Research at Dana-Farber Cancer Institute. All of the study authors reported disclosures with the sponsor, Pfizer, or other pharmaceutical companies.
