Abstract

Objective: A reliable prognostic indicator in patients with pathologic T1a renal cell carcinoma has not yet been fully elucidated. The aim of this study was to investigate the prognosis of pathologic T1a renal cell carcinoma cases with a special focus on pathological factors. Methods: The study population consisted of 338 patients diagnosed with solitary renal cell carcinoma at our hospital between 1996 and 2009. The relationship between disease pro-gression and clinicopathologic features was analyzed retrospectively to determine if it affected recurrence and distant metastasis. Results: The Fuhrman nuclear grade distribution between the tumors was 1, 2, 3 and 4 in 68 (20.1%), 242 (71.6%), 21 (6.2%) and 7 cases (2.1%), respectively. A total...
