[Prognostic factors in organ-confined renal epithelial tumors]. / Fattori prognostici nei tumori renali epiteliali organo-confinati.

ABSTRACT

Recent application of molecular cytogenetic techniques to the evaluation of epithelial renal cell tumors have showed some characteristic combinations of genetic alterations within the chromosomal DNA. Moreover each group of abnormalities has been correlated with peculiar tumor morphology. The new classification of renal cell neoplasms proposed by G. Kovacs, based on specific genetic alterations, and histologic pattern, together with the morphologic and pathologic features that correlate with survival has been discussed.
