Hepatic Resection for Hepatocellular Carcinoma with Obstructive Jaundice due to Biliary Tumor Thrombi

Hepatocellular carcinoma (HCC) with obstructive jaundice due to biliary tumor thrombi is uncommon, and few studies have examined the outcome of hepatectomy for HCC with this unusual entity. This study examined the clinicopathologic factors influencing the outcomes of 17 HCC patients with obstructive jaundice due to biliary tumor thrombi undergoing hepatectomy. The clinical features of 17 HCC patients with obstructive jaundice due to biliary tumor thrombi (group A) undergoing hepatectomy from 1986 to 1998 were reviewed. The clinical features and factors influencing the outcome of 555 HCC patients without biliary tumor thrombi (group B) undergoing hepatectomy were used for comparison. Of 572 patients with surgically resected HCCs, 17 (3.0%) were classified into group A. Right upper quadrant pain, physical signs of jaundice, low albumin level, elevated bilirubin level, small tumor size, more vascular invasion, and tumor rupture were characteristic of group A patients. Multivariate stepwise logistic regression analysis revealed no independently significant factor differentiating group A patients from group B patients. The disease-free survival was similar between the group A and B patients, although group B patients exhibited significantly better overall survival (p = 0.014). Vascular invasion may adversely influence overall survival in group A patients undergoing hepatic resection (p = 0.0709). When feasible, hepatic resection is the preferred treatment for HCC patients with obstructive jaundice due to biliary tumor thrombi. It can achieve a disease-free survival comparable to that of HCC patients without biliary tumor thrombi. However, HCC patients with biliary tumor thrombi had significantly worse overall survival than did those without biliary tumor thrombi, especially those with concomitant vascular invasion.
