[Concentration of asbestos fibers in urothelial tumors and in the neoplasm-free bladder wall].

The aim of our study was to search the eventual presence of asbestos fibers in the neoplastic tissue of 13 cases of bladder carcinoma and in the normal vesical tissue of 12 control cases without neoplasia and operated upon for other urologic pathologies. To all patients a standardised questionnaire has been administered in order to ascertain the entity of the eventual exposition to asbestos. The organic component of the tissues has been oxidated at low temperature in atomic oxygen plasma and the residual inorganic component has been analysed by transmission electronic microscopy and energy dispersion spectrometry.

Cis-diamminedichloroplatinum activity in bidimensionally measurable metastatic lesions of bladder carcinoma.

Cis-diamminedichloroplatinum (CDDP) was administered i.v., at the dosage of 20 mg/m2 for 5 consecutive days and recycled every 3 weeks, to 11 patients with bidimensionally measurable metastatic lesions from bladder cancer previously untreated with antineoplastic drugs.
