Tumor lateralization’s role is still debated. Our study examined how tumor localization affects survival in metastatic RCC patients.Materials and Methods: The study retrospectively analyzed 80 patients with metastatic renal cell carcinoma, diagnosed between January 1999 and December 2021.
Results: Eighty patients were evaluated. The median age at diagnosis was 60 (range 37-86). Tumors were in the right kidney for 39 patients (48.8%) and in the left kidney for 41 patients (51.2%). Of these patients, 58 (72.5%) had de novo metastatic disease, while 22 (27.5%) had recurrences during follow-up. Tumor localization showed no significant association with age (p=0.684), gender (p=0.761), ECOG performance status (p=0.326), primary tumor surgery (p=0.697), or lung metastasis (p=0.495). However, a significant association was found with liver metastasis (p=0.032). There was no significant difference in median survival between right and left-sided tumors (p=0.266).
Conclusion: In our study, survival showed no correlation with tumor lateralization in metastatic RCC.}, number={2}, publisher={Adıyaman University}, organization={The authors received no financial support for the research and/or authorship of this article.}
