The Relationship of Fuhrman Nuclear Grade, Tumor Stage and Sarcomatoid Differentiation with Survival in Renal Cell Carcinomas

Abstract

Objective: Renal cell carcinoma derived from tubular epithelium is one of the malignant tumors of the kidney. We have investigated the histological features, pathological stage, nuclear grade and sarcomatoid differentiation of these tumors. Results: In our study, cases with high nuclear grade, advanced stage and sarcomatoid differentiation revealed poor survival rates (p<0.05). In conclusion, the correlation between prognostic histopathological parameters and survival rates was consistent with literature findings.Conclusion: Fuhrman nuclear grading, stage and sarcomatoid differentiation are important parameters and are related factors in survival when investigating renal cell carcinomas. Fuhrman nuclear grading must be evaluated correctly and the highest grade should be reported. Although there aren't enough studies about sarcomatoid differentiation, its presence significantly decreases survival rates. It is very important to state histopathological parameters including sarcomatoid differentiation precisely on the pathology report.
