[Risk of suffering from a second primary neoplasm in patients with bladder tumor].
An evaluation was made on the risk of having a second primary neoplasia following vesical tumor diagnosis. All patients attended the 'Hospital La Fe' and had been diagnosed between 1984 and 1993. A total of 238 vesical tumours were studied, 45 (15.9%) with associated second neoplasia; in 34 cases the vesical tumour was the first one to be diagnosed. The number of tumors seen was compared to expected figures, according to the appropriate incidence rates by age, sex and tumour type, taken out from the Spanish section of the 1987 edition of "Cancer Incidence in Five Continents". An increase over the expected values of second neoplasias for lung, prostate, kidney and bone cancer was found. Sixty percent developed concurrently (within 6 months from initial diagnosis). Most vesical tumours were infiltrant, thus conditioning both the prognosis and the second neoplasia. The likely factors implied in this phenomenon are discussed.
