title: [Incidental renal cell carcinoma: clinical and morphological features].
abstract: This article is devoted to the evaluation of features of incidental, or asymptomatic renal cell carcinoma (RCC). The study included 268 patients with RCC aged 25 to 92 years who underwent examination and treatment in the urological clinic MRSRCI for the last 5 years. 163 (60.8%) patients had incidental renal tumors (Group 1), 105 (39.2%)--symptomatic renal tumors (Group 2). In incidental renal tumors, tumor nodule was smaller compared with symptomatic RCC--5,74 +/- 3.0 vs 6.4 +/- 3.6 cm. Stage I and II disease was diagnosed in 130 (79.7%) patients in Group 1 and only in 69 (65.7%) patients in Group 2 (P < 0.05). No significant differences in the distribution of the degree of nuclear atypia according Fuhrman nuclear grade were identified. The organ preservation surgery were performed more frequently in incidental RCC than in symptomatic RCC, in 47 (28.9%) and 21 (20%) cases, respectively; in addition, regional and distant metastases were diagnosed less frequently. With this in mind, it should be suggested that incidental tumors have a better prognosis than tumors with clinical manifestations.
