Purpose
To assess the safety and effectiveness of transarterial chemoembolization (TACE) of patients who have hepatocellular carcinomas (HCCs) with central bile duct invasion.
Materials and Methods
The institutional review board approved this retrospective study and waived informed consent. Fifty-three patients, initially treated with TACE for HCCs with central bile duct invasion from January 1999 to September 2012, were included. Clinical, laboratory, and survival data were reviewed. Complications and hospitalization length were evaluated using the χ
2 test, Fisher’s exact test, and logistic regression analysis. Survival was analyzed using the Kaplan–Meier method with log-rank test and Cox proportional hazard model.
Results
Seven patients experienced TACE-related major complications (severe post-embolization syndrome in 3, non-fatal sepsis in 3, and secondary bacterial peritonitis in 1). The overall major complication rate was 13.2 %, but there were no permanent adverse sequelae or deaths within 30 days. Serum total bilirubin ≥3.0 mg/dL was the only significant risk factor for long hospitalization [hazard ratio (HR) = 4.341, p = .022]. The median survival was 12.2 months. Extrahepatic metastasis (HR = 6.145, p < .001), international normalized ratio (PT-INR) ≥1.20 (HR = 4.564, p < .001), vascular invasion (HR = 3.484, p = .001), and intermediate tumor enhancement (HR = 2.417, p = .019) were significantly associated with shorter survival.
Conclusion
TACE can be a safe and effective treatment for patients who have HCCs with central bile duct invasion. In particular, long-term survival can be expected if patients have strongly enhancing tumors without poor prognostic factors such as extrahepatic metastasis, PT-INR prolongation, and vascular invasion.
