Abstract
The influence and the interdependence of pathological and clinical factors on prognostic differences between renal cell carcinoma (RCC) with end-stage renal disease (ESRD) and RCC without ESRD after nephrectomy has remained unclear. We compare the clinicopathological features between RCC with and without ESRD.From June 1993 to May 2000, 150 RCC patients who underwent nephrectomy were pathologically defined to have pT1 to pT3NXM0. The patients were followed for 1 to 84 months (median 30 months) after the surgery. Total of 16 patients with ESRD and 134 patients without ESRD were studied, and the differences of clinicopathological features between two groups were statistically compared.We compare the clinicopathological features between RCC with and without ESRD. Patients' age, tumor size, rate of incidental cancer, pathological T stage, and grade were not significantly different between two groups. The 5-year recurrence-free probability rate was significantly higher in patients without ESRD than in patients with ESRD (log-rank test: p = 0.04). The status of ESRD, patients age and pathological T stage were significant predictors of recurrence when analyzed by Cox proportional hazards analysis (p = 0.01, p = 0.03 and p = 0.02, respectively).This study demonstrated that the ESRD is an independent prognostic factor in RCC patients after surgery. These results reflect that the patients with ESRD have higher risk of tumor progression. Therefore, early detection of tumors is particularly important in these patients by regular abdominal ultrasound or CT screening.
