Ultrasound-guided percutaneous ethanol injection under general anesthesia for the treatment of hepatocellular carcinoma on cirrhosis: Long-term results in 268 patients

Objective: Percutaneous ethanol injection (PEI) under general anesthesia (One-shot PEI) is a therapy for large and multiple hepatocellular carcinoma (HCC) by the injection of a large amount of ethanol into the tumor. We report our results with 5-year survival rates in patients with HCC on cirrhosis treated with One-shot PEL Patients and methods: From October 1992 to March 1998, 268 cirrhotic patients (age 42-82 years; 191 males; 95 Child-Pugh's A class, 150 B and 23 C class of cirrhosis) with 515 HCC nodules underwent One-shot PEL Diameter of HCC nodules ranged from 0.6 to 14 cm (mean 5.02 ± 2.2 cm; median: 4 cm). One hundred and thirty-eight patients had a single nodule (range 3.2-14 cm; mean 5.6 ± 2.1 cm), 130 had multiple nodules, up to six nodules (mean 2.9 nodules) (range 0.6-11 cm; mean 4.8 ± 2.1 cm) Results: CT showed complete necrosis in 357/506 nodules (70%). Five patients (1.8%) with nine nodules died as a result of the procedure (variceal bleeding in three cases, liver failure in one and hemoperitoneum in one). The overall survival rates were 93, 83, 74, 65 and 59% at 1, 2, 3, 4 and 5 years, respectively. Survival rates were 90, 84, 82 and 82% at 12, 24, 36 and 48 months, respectively, in patients with a single nodule [less-than or equal to] 5 cm, and 97, 71, 59, 59 and 59% at 12, 24, 36, 48 and 60 months, respectively, in patients with single nodule >5 cm. Patients with multiple nodules had survival rates of 97, 89, 75, 60 and 60% at 12, 24, 36, 48 and 60 months, respectively. Conclusion: PEI of large and multiple HCC showed survivals similar to conventional PEI for patients with smaller tumors. © 2000 Elsevier Science Ireland Ltd. All rights reserved.
