title: [Superficial bladder carcinoma: clinical and epidemiological analysis of 250 patients].
abstract: The neoplasms of bladder are an important part of genitourinary tumors. Superficial forms represent 70-80% of their overall number. We have carried out a retrospective clinical and epidemiological study of 250 patients seen in our service during a 12-year period. We found that the disease was more common in males aged 60-70 years, usually being multiple tumors and mostly in the lateral walls of the bladder. Most tumors were in grades 1 and 2 of UICC and in stage O of Jewett's classifications, with a clear association between the degree of cell differentiation and the stage of infiltration. There was no correlation of age and sex with the number of tumors, their localization, cellular degree and tumor stage. There was a correlation between the number of tumors and their localization; thus, single tumors had a preference for lateral walls, while multiple tumors predominated in the bladder fundus.
