Advanced clear-cell adenocarcinoma of the bladder successfully treated by radical surgery with adjuvant...

A 52-year-old woman was referred to our institute for the evaluation of a tumor in her pelvic cavity. The tumor seemed to have arisen from the bladder or urethra, and bilateral iliac lymphadenopathy was seen. Her urethral mucosa looked intact according to the results of cystourethroscopy. Histopathological examination of the biopsy specimens showed clear-cell adenocarcinoma. She underwent radical cystourethrectomy with complete pelvic lymph node dissection and the construction of a bilateral ureterocutaneostomy. Macroscopically, the tumor had arisen from the trigone of the bladder, and histopathological examination of the tumor revealed adenocarcinoma exhibiting solid clear cells with glandular and papillary patterns. The tumor had infiltrated perivesical structure (pT3a), and metastases in multiple pelvic lymph nodes were recognized (pN3). Postoperatively, three courses of systemic combination chemotherapy with 5-fluouracil (FU) and cisplatin, along with a total of 45 Gy of irradiation during the second course of chemotherapy, were conducted. No evidence of the disease has been seen 28 months after the surgery.
