Stage P1 primary neoplasias of the bladder. A critical study of the results obtained with adriamycin and mitomycin C in the prophylaxis of recurrences [NEOPLASIE PRIMITIVE DELLA VESCICA ALL STADIO P1. VALUTAZIONE CRITICA DEI RISULTATI OTTENUTI CON L'IMPIEGO DELL'ADRIAMICINA E DELLA MITOMICINA C NELLA PROFILASSI DELLE RECIDIVE]

However adequately treated, surface carcinomas of the bladder recur sooner or later with infiltration found in about 10% of cases. Any development that may offer therapeutic progress and reduce the incidence of recurrences is therefore of primary importance. Two homogeneous groups of patients were selected for the present study: 35 were given Adriamycin and 25 Mitomycin C. In evaluating results, the incidence of recurrences in relation to the primary neoplasia and the existence of single or multiple tumors was analysed. It is concluded that Mitomycin C in association with either T.U.R. or T.V.R. is particularly useful and indubitably effective form of topical chemotherapy in cases of single or multiple primary neoplasia.
