内容記述
Case 1 : A 48-year-old man presenting with gross hematuria was suspected to have a tumor located in the bladder dome. He was referred to our department for further examination and treatment. Cystoscopy showed a dome-shaped mass in the supravesical region. Computed tomography and magnetic resonance imaging indicated the possibility of urachal carcinoma and peritoneal dissemination. Therefore, partial cystectomy with urachal resection was performed. The intraoperative findings were disseminated peritoneal nodules and mucus entering the peritoneal cavity from the tumor. On pathological examination, the tumor was classified as a mucinous-type adenocarcinoma, and 6 courses of TS-1/cisplatin (CDDP) therapy were administered to the patient as adjuvant chemotherapy. To date (10 months since the surgery), there has been no disease progression. Case 2 : A 76-year-old woman was referred to our department with a finding of a tumor in the bladder dome during her detailed examination for lung tumors. Cystoscopy showed nodular tumors, indicating lung metastases of the urachal carcinoma. Therefore, partial cystectomy with urachal resection was performed. On pathological examination, the tumor was classified as an enteric-type adenocarcinoma, and 2 courses of TS-1/CDDP therapy were administered to the patient as adjuvant chemotherapy. However, due to the development of marked bone marrow depression, the drugs had to be discontinued. Nonetheless, the lung metastases markedly diminished in size. To date (9 months since the discontinuation of chemotherapy), there has been no disease progression.
