[The morphogenic characteristics of human transitional-cell bladder tumors in Ukraine after the accident at the Chernobyl Atomic Electric Power Station].
A study made into the morphogenesis of transitional cell tumors of human urinary bladder in 226 patients before the Chernobyl Nuclear Power Plant breakdown (I period of investigation) and 608 patients and majority of whom have been living in those regions of Ukraine affected by contamination with radionuclides as a result of the Chernobyl accident (II period of investigation) revealed decline in the prevalence of transitional cell papillomas, younger age of patients, greater incidence of invasive varieties of moderately differentiated, poorly differentiated (high-grade) transitional cell carcinoma, an unusual frequency of transitional cell carcinoma presenting with foci of multilayer planocellular metaplasia, lymphoidocellular infiltration, recurrent inflammation, foci of necrosis and hemorrhages.
