A 67-year-old woman complained of urinary frequency and gross hematuria. She was referred to our hospital with the diagnosis of bladder tumor. Transurethral resection of the bladder tumor (TURBT) was performed and pathological diagnosis was urothelial carcinoma (G2>G3) with muscular invasion. Because she hoped bladder preservation therapy, she received two courses of M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) therapy, one course of arterial infusion chemotherapy, and chemoradiotherapy with cisplatin. After those therapies she underwent 4 times of TURBT and two courses intravesical BCG therapy. However, solitary lung metastasis appeared 19 months after the initial TURBT. Multidisciplinary treatments including 25 courses of various multiagent chemotherapies, radiation therapy to the lung metastasis and surgical resection of a urethral recurrence were performed. Although a localized radiation pneumonitis was developed, the lung metastasis appeared to be controlled for 26 months after the radiation therapy to the lung. Bilateral ureteral and renal pelvic tumors appeared after the radiation therapy. Severe bleeding was occurred from renal pelvic tumors several times and she needed the hospital stay 2 times. Active bleeding stopped after the administration of chemotherapy each time. Although she died of occlusive jaundice due to the liver metastasis, she had been alive due to the multidisciplinary treatment for 67 months after lung metastasis appearance with relatively good performance status.
