Objectives: To compare overall survival (OS), recurrence free survival (RFS), and cancer-specific survival (CSS) in the long-term follow-up of T1 and T2 clear-cell-Renal Cell Carcinoma (ccRCC) and papillary Renal Cell Carcinoma (pRCC) patients, as well as to determine the risk factors for recurrence and overall mortality. Material and method: Data of patients with kidney tumors obtained from the Urologic Cancer Database -Kidney (UroCaD-K) of Turkish Urooncology Association (TUOA) were evaluated retrospectively. Out of them, patients who had patho-logical T1-T2 ccRCC and pRCC were included in the study. According to the two histological subtype, recurrence and mor-tality status, RFS, OS and CSS data were analyzed. Results: RFS, OS and CSS of pRCC and ccRCC were found to be similar. Radiological local invasion was shown to be a risk fac-tor for recurrence in pRCC, and age was the only independent factor affecting overall mortality. Conclusions: There were no differences in survivals (RFS, OS and CSS) of patients with localized papillary and clear cell RCC. While age was the only factor affecting overall mortality, radiological local invasion was a risk factor for recurrence in papillary RCC.
