Case of carcinosarcoma of urinary bladder obtained a pathologically complete response by neoadjuvant chemoradiotherapy.
Carcinosarcoma of the bladder is an unusual malignancy characterized by an intimate admixture of malignant epithelial elements (carcinoma) and malignant soft tissue elements (sarcoma). To our knowledge, almost 80 cases have been reported, usually as case reports or small series. Patient with carcinosarcoma usually present with a high stage malignancy. Cystectomy or transurethral resection is the preferred treatment, often followed by radiation therapy, although prognosis is very bad. We herein report a case of carcinosarcoma of bladder obtained pathologically complete response by neoadjuvant chemoradiotherapy. She now shows no evidence of disease 30 months after the operation. To our knowledge, it is the first case where urinary bladder carcinosarcoma obtained a pathologically complete response by chemoradiotherapy.
