Indications for Palliative Reduction Surgery for Hepatocellular Carcinoma with Multiple Intrahepatic Metastases

We evaluated the efficacy of and the indications for palliative reduction surgery as a procedure to improve the prognosis of hepatocellular carcinoma (HCC) patients with multiple intrahepatic metastases. From January 1986 to October 1997, 25 HCC patients with multiple intrahepatic metastases who underwent necessary palliative reduction surgery due to advanced disease, were participated in the study. The 1-, 3-, 5-year survival rates of 25 patients with reduction surgery were 54.7%, 29.9%, 22.4%, respectively. Moreover, the 1-, 3-, 5-year survival rates of patients with some postoperative supplemental treatment were 68.8%, 41.2% and 30.9%, respectively. All 6 patients who had been alive for more than 3 years had had primary tumors with diametric sizes of approximately 5 cm and had undergone, at most, one segmentectomy. These patients received postoperative supplemental treatments. The indication for palliative reduction surgery for HCC patients with multiple intrahepatic metastases was patients with a relatively small primary tumor (around 5 cm) which could be removed by one segmentectomy or less

Thoracoscopic Microwave Coagulation Therapy for Hepatocellular Carcinoma

Thoracoscopic microwave coagulation therapy (MCT) is a new therapeutic approach for hepatocellular carcinoma (HCC) in segments VII and VIII, which allows minimal access to the tumor and complete tumor ablation. In this study, four patients with HCC in segments VII and VIII underwent thoracoscopic MCT as a less invasive therapeutic option due to advanced liver cirrhosis and/or severe complications. Tumor sizes ranged from 15 to 30 mm in diameter and the tumors were well differentiated in 2 patients, moderately in one and poorly in one patient. Microwave irradiation was performed at an SOW output with a 60-sec duration via a thoracoscopic route and the total duration ranged from 4 to 24 min (mean: 17 min). Patients recovered rapidly to preoperative conditions and no mortality was occurred. Complications were observed in one patient, including pleural effusion and fever elevation, but were cured conservatively. Postoperative computed tomography (CT) showed complete tumor ablation with a cancer-free margin, which is thought to be equivalent to a limited hepatic resection. This preliminary study suggests that thoracoscopic MCT might be a new, less invasive option providing a cure for HCC in segments VII and VIII in patients with advanced liver cirrhosis and severe complications
