Radiation-induced cystitis following intracavitary irradiation for superficial bladder cancer.
Intracavitary irradiation is effective in the treatment of noninvasive papillary transitional cell carcinoma and carcinoma in situ of the bladder. Mortality has not been associated with this form of therapy. The morbidity associated with intracavitary irradiation consists of mild to severe radiation cystitis and we report 2 such cases. One patient is from a series of 65 patients with noninvasive bladder tumors treated with intracavitary irradiation at this clinic since 1965. The second patient had noninvasive bladder tumors and was treated with intracavitary irradiation elsewhere. In both patients severe radiation cystitis subsequently developed, requiring simple cystectomy and urinary diversion. The potential for this serious side effect must be considered when choosing a form of therapy for patients with noninvasive papillary transitional cell carcinoma and carcinoma in situ of the bladder.
