Structure and size versus prognosis in nephroblastoma

Abstract

A series of 112 children with nephroblastoma were analyzed with respect to clinical factors, structure, tumor size, and treatment. The statistical method employed was a multivariate analysis. Histologically, the tumors were classified according to their degree of tissue differentiation and cellular atypia as three different types. Histologic type, stage, and irradiation had a positive correlation to prognosis. Age of the patient, tumor size, method of treatment, and year of admission did not influence the prognosis significantly.
