Abstract
Some patients who achieve a sustained virological response (SVR) to interferon (IFN) treatment for chronic hepatitis C prior to hepatic resection for hepatocellular carcinoma (HCC) experience postoperative recurrence. This study investigated the relationship between obesity and postoperative HCC recurrence in SVR patients. Fifty-nine patients who had achieved SVR before hepatic resection were evaluated. Patients had a solitary tumor ≤5 cm in diameter or ≤3 lesions each ≤3 cm in size with no macroscopic vascular invasion (Milan criteria). Patient characteristics potentially associated with recurrence risk were investigated. Three-, 5-, and 7-year recurrence-free survival after surgery were 65%, 44%, and 41%, respectively. Univariate analysis showed that obesity (P < .01), hypertension (P = .038), and non-anatomical resection (P = .022) were significantly associated with a lower recurrence-free survival rate. In a multivariate analysis, obesity (hazard ratio, 2.8; 95% confidence interval [CI] 1.3-6.1; P < .01) and non-anatomical resection (hazard ratio, 2.7; 95% CI 1.1-6.2; P = .025) were independently associated with postoperative recurrence. Three-, 5-, and 7-year overall survival rates after surgery were 100%, 80%, and 64% in ...Continue Reading
