Abstract: | A 29-year-old woman with gross hematuria was referred to our hospital. Cystoscopy revealed a nonpapillary broad-based tumor on the right lateral wall of the urinary bladder, which a transurethral biopsy identified as transitional cell carcinoma (G2). CT and MRI suggested that the carcinoma invaded beyond the bladder wall. We performed a radical cystectomy with hysterectomy and the construction of an ileal neobladder. Pathological examination of the specimen indicated that it was small-cell undifferentiated carcinoma at the stage of pT2bpN0. For adjuvant chemotherapy, four cycles of CPT-11 and CDDP chemotherapy were performed, which is currently the usual chemotherapy for small-cell lung carcinoma in Japan. The patient is alive without any evidence of tumor recurrence at 12 months after surgery. |
