Renal cell carcinoma: histological findings in peritumoral tissue after organ-preserving surgery.

Abstract

This study assessed the involvement of peritumoral renal cell carcinoma tissue and evaluated the efficacy of partial resection versus enucleation by an anatomopathological investigation into the resection margins in 28 cases of partial nephrectomy. Histological findings showed no peritumoral infiltration in 91.6% of elective partial resections (24 patients) and resection margin involvement in 75% of necessary partial resections (4 patients). Although the debate between organ-preserving and radical surgery remains open, the conservative approach can undoubtedly be recommended in selected patients.
