Abstract

Purpose: We determined the clinical and pathological features associated with death from papillary renal cell carcinoma in 395 surgically treated patients. Materials and Methods: Papillary renal cell carcinoma tissue slides from each patient were reviewed for type (1 or 2), grade, TNM stage, coagulative tumor necrosis and sarcomatoid differentiation. Associations of clinical and pathological features with death from renal cell carcinoma were evaluated using Cox proportional hazards regression models and summarized by the HR and 95% CI. Cancer specific survival was estimated using the Kaplan-Meier method. Results: Univariate analysis revealed that symptoms, tumor thrombus, tumor size, perinephric/renal sinus fat invasion, 2010 primary tumor classification, regional lymph node involvement, distant metastasis, 2010 TNM stage group, grade, tumor necrosis, sarcomatoid differentiation and papillary renal cell carcinoma type were associated with death from renal cell carcinoma. Grade was more strongly associated with death from renal cell carcinoma than papillary renal cell carcinoma type. Multivariate analysis indicated that symptoms, 2010 TNM stage group and grade jointly were significantly associated with death from renal cell carcinoma. Conclusions: This large series of patients with papillary renal cell carcinoma reveals features associated with death from renal cell carcinoma and confirms that grade is more predictive of outcome than papillary renal cell carcinoma type.
