- Abstract
Clear cell renal cell carcinoma (CCRCC) is the most frequent type of renal cell carcinoma. Fuhrman grade and tumor stage are prognostic factors with great importance in survival rate. This study was performed on 75 cases of CCRCC diagnosed in the Anatomical Pathology Laboratory of the County Clinical Emergency Hospital of Craiova between 2014 and 2017. The biological material was represented by pieces of nephrectomy. The cases were analyzed on two criteria: epidemiology (age, sex) and histopathology (Fuhrman grade, tumor stage, architectural pattern, sarcomatoid transformation, and necrosis). Statistical analysis was done using Chi Square tests. Average diagnosis age of CCRCC was 58.8±10.2 years, predominantly in male patients (66.7%). Tumor sizes were between 2 and 14cm, with an average of 6.7±2.9cm. Most cases were determined to be tumor stage III (60%) and Fuhrman grade 2 (56%), followed, in order of frequency, by tumor stages I and II (28% and 10.7%) and Fuhrman grades 3 and 1 (21.3% and 20%). High Fuhrman grade CCRCC were significantly associated with advanced tumor stage (p<0.05, 2 test). Most cases presented a mixed pattern, significantly associated with advanced tumor stages (p<0.05, 2 test). Even though the presence of sarcomatoid transformation was more frequent in advanced tumor stages, it wasn't significantly linked to them (p<0.05, 2 test). Conclusions: Analyzed histopathological parameters are useful for determining CCRCC aggressiveness. CCRCC in advanced tumor stages is associated with high Fuhrman grade and mixed architectural pattern.
