Abstract

Purpose: We aimed to compare oncological outcomes in the two rare subtypes, unclassified renal cell cancer (unRCC) and translocation RCC (tRCC), vs clear cell RCC (ccRCC).
Materials and Methods: Between 2004 and 2019, from Turkish Urooncology Society Database, we identified 2324 patients for histological subtypes including 80 unRCC (3.4%), 19 tRCC (0.8%) and 2225 ccRCC (95.8%).
Results: The overall (15.8%) and cancer-specific mortalities (11.1%) were found to be higher in tRCC group and the recurrence free mortality (13.8%) was found to be higher in unRCC group. Larger pathological tumor size (p = 0.012) and advanced pathological T stage (p = 0.042) were independent predictive factors on overall mortality in patients with unRCC tumors.
Conclusion: The oncological outcomes of the unRCC and tRCC are worse than ccRCC and pathological tumor size and pathological stage are predictive factors for mortality in the unRCC.
