Cytologic Diagnosis in Bladder Carcinoma Treated by Supervoltage Irradiation

Abstract

In 160 cases of carcinoma of the urinary bladder treated with supervoltage irradiation, cytologic examination of the urine and bladder washings was included in frequent follow-up examinations. Persistence or recurrence of carcinoma was clinically diagnosed in 79 patients. In 89 per cent of them the clinical diagnosis was cytologically confirmed. The factors influencing the accuracy of the cytologic diagnosis of malignancy following irradiation are discussed.
