[Prognostic criteria in renal cell cancer].

Survival of 94 patients with hypernephroma is evaluated kinetically. The following factors were analysed: sex, age, tumour size, tumour invasion in the fibrous renal capsule, venous invasion, morphologic variant of the tumour, differentiation degree, angiographic tumour type. The main factors affecting the prognosis appeared to be tumour invasion in the fibrous renal capsule and the degree of tumour differentiation. Adenocarcinoma has a better prognosis.
