    Non-clear cell renal cell carcinoma (non-ccRCC) includes histologically and molecularly distinct subtypes, such as papillary, chromophobe, collecting duct, and sarcomatoid RCC, with an incidence of 20% to 25%

    The study used the National Cancer Database to screen patients with non-metastatic RCC (T1-4, N0-1) between 2004 and 2015


    The study used the National Cancer Database to screen patients with non-metastatic RCC (T1-4, N0-1) between 2004 and 2015


    Overall, our analysis included 220,170 patients with RCC


    The median follow-up time for patients with all histological subtypes was 48.



    Differences in prognosis of non-clear cell renal cell carcinoma (non-ccRCC) subtypes

    Multivariate analysis included 6723 chromophobe, 188 collecting duct, 19086 papillary, and 1083 sarcomatoid RCC

    Well-differentiated (HR = 0.



    In terms of surgical treatment, no surgery (HR = 2.

    Regional lymph node surgery was associated with worse survival outcomes compared with surgery without regional lymph nodes (HR = 1.


    Taken together, our study demonstrated that collecting duct and sarcoid histological subtypes are less common and associated with poorer postoperative survival compared with other RCC subtypes
