Long-Term Survival of an Elderly Patient with Carcinosarcoma of the Gallbladder after Cholecystectomy

Carcinosarcomas, often referred to as malignant mixed tumors, are rare neoplasm. We reported herein a carcinosarcoma of the gallbladder in an elderly patient with long-term survival (4 years). The operation carried out was open cholecystectomy under the preoperative diagnosis of chronic cholecystitis and tumor of the gallbladder. Anticancer chemotherapy after cholecystectomy was performed by oral low-dose FT therapy. He was alive with no evidence of disease 48 months after surgery. Long-term survival for only cholecystectomy treatment as in this case may be possible if oral low-dose FT anticancer therapy is effective against carcinosarcoma of the gallbladder.
