Abstract

Successful hepatic resection with combined inferior vena cava (IVC) resection has been reported. The necessity of a combined IVC resection for hepatic malignancies that have attached to the IVC has not been fully evaluated. In this retrospective study, 162 lesions for which preoperative CT findings suggested attachment to the IVC were evaluated. Patient survival rates were examined according to type of tumor and the operative procedure. For adenocarcinoma lesions, several CT findings, including extent of the IVC circumference attached to the tumor compared with the whole IVC circumference (E(IVC)), were evaluated in conjunction with IVC resection. Among 162 lesions, 18 adenocarcinoma lesions were resected in combination with an IVC resection. Histologic IVC invasion was confirmed in eight patients. None of the 67 hepatocellular carcinoma lesions required concomitant IVC resection. Overall 5-year survival rate of the patients who underwent concomitant liver and IVC resections was 33.1%. Among the adenocarcinoma lesions, the positive predictive factors for IVC resection were an E(IVC) value > 25% and a peaked deformity of the IVC wall, according to a multivariate analysis. Most hepatic malignancies attached to the IVC wall can be...Continue Reading
