[Clinical significances of intraoperative radiation therapy for aged patients with bladder cancer].
Seven elderly patients, 79-88 years old, with bladder cancer were treated by transvesical tumorectomy with intraoperative radiation therapy (IORT). The cancers appeared to be of high grade and high stage by cystoscopy and other examinations, and consequently they were diagnosed to be over stage T2. Therefore, all patients were thought to be candidates for total cystectomy. But their ages and complications precluded this treatment, so we decided to carry out the "palliative" IORT. The operation of IORT required less than two hours and required less than 200 ml of blood loss. There were no complications such as hematuria, irritable bladder, and rectal symptoms. The postoperative stage diagnoses coincided with the preoperative ones in 5 cases, but two cases were overdiagnosed. Five patients died after more than one year and 11 months, but four patients died due to other diseases, without cancer. One patient died due to pulmonary cancer confirmed by autopsy. Recurrence was seen in one case. These results confirmed that IORT was effective for local control of bladder cancer and partially prophylactic for recurrence. Furthermore, this treatment seemed to be even curative for some cases. We recommend this modality of treatment for some of aged patients and patients with complications who are unable to undergo cystectomy.
