[Clinico-pathologic study of renal cell carcinoma].
Renal cell carcinoma (RCC) is an uncommon tumour with high mortality mainly due to late diagnosis. The various morphological variables and the clinico-pathological stage, however, induce highly different evolutions. Awareness of these characteristics would be a significant part of deciding the most appropriate therapy for each case. The pathological anatomy of 130 renal cell carcinomas obtained through nephrectomy was reviewed. A follow-up of at least 5 years was done in 121 patients. Also, a survival study related to the various clinical and pathological parameters was carried out. A significantly lower survival rate was observed for solid tumours with spindle or giant cells and nuclear degrees superior to 2, over 10 mitosis in 10 fields and staging higher than II. A significant correlation was also found between number of mitosis and staging, presence of metastatic disease, survival interval, degree of tumoral necrosis, histological type, cell type and nuclear grade. Our results indicate that staging, histological type, cell type, microscopic vascular infiltration, nuclear grade and number of mitosis can be highly predictive of the evolution and prognosis of RCC patients.
