Experience with liver resection after hepatic arterial chemoembolization for hepatocellular carcinoma.
The use of percutaneous transcatheter hepatic arterial chemotherapy and embolization in the treatment of primary liver cancer has become increasingly popular in recent years. The authors employed this method, using a combination of cisplatin, mitomycin C, 5-fluorouracil, and ethiodized oil (Lipiodol) or absorbable gelatin sponge in 30 patients with huge liver cancers (diameter range, 5.6-12.0 cm) as a preliminary treatment before liver resection. Significant tumor regression occurred after this treatment, converting these tumors into resectable lesions that were excised successfully later. Before surgery, chemoembolization was done once every 4-6 weeks. The patients underwent 1-5 treatment sessions (mean, 2.9) and then waited 1-4 months (mean, 2.4 months) before undergoing surgery. Alpha-fetoprotein levels decreased to normal in seven patients. The tumor diameters were reduced by 31.6 +/- 15.2% (2.3 +/- 1.2 cm) and the percent tumor necrotic area ranged from 40-100%. Adhesions of the tumor to the diaphragm and thickening of the hepatoduodenal ligament and gallbladder wall were the primary operative findings, but they did not significantly complicate the surgery. There was one postoperative death from acute pulmonary embolism. The 1-year, 2-year, and 3-year survival rates were 88.89%, 77.03%, and 77.03%, respectively. Although these patients still are being followed to assess their long-term survival, this treatment appears promising for patients with advanced huge liver cancers who hitherto have been denied surgery on grounds of unresectability.
