Clinicopathologic characteristics of hepatocellular carcinoma with bile duct invasion.
ABSTRACT To clarify the characteristics of hepatocellular carcinoma (HCC) with bile duct invasion, we retrospectively analyzed clinical features and surgical outcome of HCC with bile duct invasion (b(+) group, n = 15) compared to those without bile duct invasion (b(-) group, n = 256). In the b(+) group, four patients (27%) showed obstructive jaundice, and a diagnosis of bile duct invasion was obtained preoperatively in seven patients (47%). The levels of serum bilirubin and carbohydrate antigen 19-9 were significantly higher in the b(+) group. Macroscopically, confluent multinodular type and infiltrative type were predominant in the b(+) group (P = 0.002). Microscopically, capsule infiltration (P = 0.040) and intrahepatic metastasis (P = 0.013) were predominant in the b(+) group. Portal vein invasion was associated significantly with the b(+) group (P = 0.004); however, the frequency of hepatic vein invasion was similar (P = 0.096). The median survival after resection was significantly shorter in the b(+) group than in the b(-) group (11.4 vs. 56.1 months, P = 0.002), and eight of 11 intrahepatic recurrences in the b(+) group occurred within 3 months after surgery. HCC with bile duct invasion has an infiltrative nature and a high risk of intrahepatic recurrence, resulting in poor prognosis.

ABSTRACT: This prospective cohort study on patients with hepatocellular carcinoma (HCC) presenting with jaundice emphasized the importance of differentiating patients with hepatic insufficiency from patients with obstructive jaundice caused by tumor. There are little data in the medical literature on the management of patients with HCC presenting with jaundice. Experience has accumulated mainly from case reports and retrospective studies. Data were collected prospectively on 2095 patients with HCC seen over a 12-year period. All patients were investigated with blood tests, abdominal ultrasound, and chest radiography. Endoscopic retrograde cholangiopancreatography-percutaneous transhepatic cholangiography, computed tomography and hepatic angiography were carried out in selected patients. Of the 530 patients who had clinically detectable jaundice, 481 had jaundice due to hepatic insufficiency and 49 patients had obstructive jaundice. Patients with hepatic insufficiency had extremely poor prognosis, and 90% of them died within 10 weeks of first presentation. "Curative" resection, however, was possible in 9 of 49 patients with obstructive jaundice, and histologic analysis showed resectional margin involvement by tumor in 1 patient. In addition, 35 patients were treated with biliary stents to relieve the obstructive jaundice. Supportive treatment only was given to five patients who were considered too terminally ill. The overall survival of patients with HCC with obstructive jaundice was similar to those patients who presented with no clinical detectable jaundice and was much better than those with jaundice due to hepatic insufficiency (log-rank test, p < 0.001). The prognosis of patients with HCC who presented with jaundice due to hepatic insufficiency was dismal. It is important to identify the patients who had obstructive jaundice because with proper treatment, good palliation and occasional cure are possible.Annals of Surgery 04/1997; 225(3):281-5. · 6.33 Impact Factor

ABSTRACT: The aim of this study was to evaluate the clinicopathologic characteristics of patients with hepatocellular carcinoma (HCC) and bile duct thrombi (BDT). Seventeen patients with HCC and BDT among 671 patients with HCC who underwent hepatic resection were enrolled in this study. There were no significant differences in the survival rates between patients with and those without BDT, although the rate of stage IV or portal vein invasion was significantly higher in patients with HCC and BDT than in those with HCC but without BDT. In 9 of 17 patients with BDT, preoperative jaundice was observed. Five of the 17 patients underwent a bile duct resection combined with hepatic resection, and 12 patients underwent hepatic resection with removal of the BDT without bile duct resection. None of the patients had histopathologic evidence of direct tumor invasion into the bile duct wall or of any tumor recurrence related to the BDT. There were no significant differences in the survival rates between patients who underwent bile duct resection and those who did not. Hepatic resection and the removal of BDT without bile duct resection were sufficient surgical interventions to treat patients with HCC and BDT.Surgery 12/2000; 128(5):779-83. · 3.37 Impact Factor

ABSTRACT: This retrospective study in eight surgically treated patients with obstructive jaundice due to biliary tumor thrombus in a patient with hepatocellular carcinoma (HCC) was performed to evaluate the role of surgical intervention. All biliary tumor thrombi were confirmed preoperatively or intraoperatively. Only two manifested intraluminal biliary obstructions due to a primary tumor that had not been found preoperatively. The operative procedures included hepatectomy with removal of the biliary tumor thrombus (n=3), hepatectomy combined with extrahepatic bile duct resection (n=1), thrombectomy through a choledochotomy (n=3), and piggyback orthotopic liver transplantation (n=1). The 1- and 3-year survival rates were 62.5% and 37.5%, respectively. Two patients survived more than 5 years. Surgical intervention was effective in patients with obstructive jaundice due to a biliary tumor thrombus in an HCC. Thus surgery for a recurrence can prolong survival, and liver transplantation is a treatment worthy of further investigation.World Journal of Surgery 02/2004; 28(1):43-6. · 2.23 Impact Factor
