BSTRACTNon-clear cell renal cell carcinoma (non-ccRCC) is a highly heterogeneous disease group,accounting for approximately 25% of all RCC cases. Due to its rarity and especially heterogen-eity, phase III trial data is limited and treatment options generally follow those of clear cell RCC.In the literature, there exists a number of studies with sunitinib, cabozantinib, and everolimus,but data on the efficacy of pazopanib are limited. Our aim in this study was to compare the effi-cacy of pazopanib and sunitinib, in a multicenter retrospective cohort of non-ccRCC patients.Our study included patients diagnosed with non-ccRCC who received pazopanib or sunitinibtreatment as first-line therapy from 22 tertiary hospitals. We compared the progression-free sur-vival (PFS), overall survival (OS), and response rates of pazopanib and sunitinib treatments.Additionally, we investigated prognostic factors in non-ccRCC. PFS and response rates of suniti-nib and pazopanib were found to be similar, while a numerical difference was observed in OS.Being 65 years and older, being in the intermediate or poor risk group according to theInternational Metastatic Renal Cell Carcinoma Database Consortium, having liver metastases,presence of a sarcomatoid component, and having de novo metastatic disease were found tobe significantly associated with shorter PFS. Pazopanib treatment appears to have similar effi-cacy in the treatment of non-ccRCC compared to sunitinib. Though randomized controlled trialsare lacking and will probably be never be available, we suggest that pazopanib could be a pre-ferred agent like sunitinib and cabozantinib.HIGHLIGHTSPazopanib and sunitinib treatments show similar progression free survival, overall survival andobjective response rate.IMDC risk group, liver metastasis, sarcomatoid component and de novo metastatic disease weredetermined as prognostic factors
