[A case of huge omental-origin liposarcoma controlled by a combination of ifosfamide and adriamycin].

A 51-year-old woman came to our hospital after a medical check -up. She suffered from abdominal distension. Abdominal CT revealed the abdominal cavity filled with omental cake. The preoperative diagnosis was unassertive. Laparotomy through midline incision was performed. The bulk of the omental tumor occupied the abdominal cavity, but infiltrated the bowel or abdominal wall less. Fractional resection of the tumor, right hemicolectomy, sigmoidectomy, wedge resection of small intestine and left ovariectomy were performed in parallel. Resected specimens weighed 6. 6 kg in total. The operation was considered palliative because of the peritoneal dissemination. Postoperative intraabdominal administration of cisplatin(50mg) made the ascites disappear. She was discharged 3 weeks after the operation. The final diagnosis was liposarcoma(myxoid type), and 5 courses of adjuvant chemotherapy with adriamycin and ifosfamide were performed. No relapse was found 11 months after the operation, but tumor regrowth occurred in the thoracic and abdominal cavity and the patient died 14 months after the operation.
