抄録: | Three cases of transitional cell carcinoma (TCC) in the urinary bladder diverticulum were encountered during a period of 12 years and bladder preserving treatments were performed. Case 1: A 78-year-old man was admitted with a chief complaint of hematuria. Papillary tumors in the diverticulum of the right bladder wall were revealed (TCC, G3, T3N0M0). Intraarterial infusion chemotherapy was performed and complete remission was achieved. When a recurrent bladder tumor appeared 22 months later, transurethral resection was performed and there was no evidence of recurrence for 50 months. Case 2: A 60-year-old man was admitted with a chief complaint of gross hematuria. Cystoscopic examination revealed papillary tumors in a bladder diverticulum near the ureteral left orifice. Transurethral resection revealed TCC G2 and carcinoma in situ. Partial cystectomy, including the bladder diverticulum, and vesicoureteral neostomy was performed. The histological stage of the tumor was pTis and the wall of diverticulum possessed a thin muscle layer histopathologically. Twenty two months later, recurrence in the left bladder wall developed and transurethral resection and bladder instillation therapy were performed. For 21 months he had no evidence of recurrence. Case 3: A 59-year-old man was admitted with a chief complaint of hematuria. A solid tumor in the diverticulum of the bladder left wall was revealed. After 4 courses of intraarterial infusion chemotherapy, 41% remission was achieved and partial cystectomy was performed. Histopathological diagnosis was TCC G3, pT3b, INF-alpha, v (-), ly (-), and no muscle layer was found in the diverticulum. There was no evidence of recurrence 16 months after operation. By using the combination therapy, bladder preserving treatment is possible in the cases of bladder cancer arising in the diverticulum. |
