Abstract:
186 cases of nephrectomy for renal cell cancer are studied retrospectively. The overall 5-year survival rate was 77.2%. According to the 4th edition of the "TNM" classification system of UICC the survival rates of patients with T2-(n = 97), T3a (n = 58) and T3b-tumors (n = 25) were 80.9%, 79.3% and 65.6%, respectively. No patient with a stage T4 tumor (n = 6) survived longer than 20 months. The 5-year survival rate of patients with N1-lymph node metastases was 83.3% (n = 8); without lymph node metastases 78.3% (n = 152), respectively. There was no survival longer than 20 months in case of N2-lymph node metastases (n = 13). According to the grading survival rates of 95.4% (G1, n = 46), 71.2% (G2, n = 130) and 71.4% (G3, n = 8) resulted.
