Abstract:
Objective:To clarify whether the surgical treatment for hilar cholangiocarcinoma combined with artery reconstruction is optimistic to the patients with hilar cholangiocarcinoma with hepatic artery invasion.
Methods:There were 384 patients who received treatment in the First Affiliated Hospital to Army Medical University from January 2008 to January 2016 analyzed retrospectively. There were 27 patients underwent palliative operation, 245 patients underwent radical operation, radical resection account for 63.8%. Patients were divided into four groups according to different operation method: routine radical resection group(n=174), portal vein reconstruction group (n=47), hepatic artery reconstruction group (n=24), palliative group(n=27). General information of patients who underwent radical operation treatment was analyzed by chi-square test and analysis of variance. The period of operation time, blood loss, the length of hospital stay and hospitalization expenses of the radical operation patients were analyzed by one-way ANOVA. Comparison among groups was analyzed by LSD-t test.
Results:The follow-up ended up in June first, 2016. Each of patients followed for 6 to 60 months, the median follow-up period was 24 months. 1-, 3-, and 5-year survival rates were 81.3%, 44.9% and 13.5% of routine radical operation group, and were 83.0%, 44.7% and 15.1% of portal vein reconstruction group, and were 70.8%, 27.7% and 6.9% of hepatic artery reconstruction group, respectively. And 1-, 3-, and 5-year survival rates of hepatic artery reconstruction group was lower than routine radical group and portal vein reconstruction group significantly (P<0.05). However, the rate of postoperative complications of the hepatic artery reconstruction group and the routine radical operation group and the portal vein reconstruction group were 62.5%(15/24), 55.3%(96/174) and 51.5%(24/47), respectively. There was no significant difference among them (P>0.05). The data shows that the ratio of lymphatic metastasis in hepatic artery reconstruction group (70.8%) is much higher than them in routine radical operation group (20.1%) and portal vein reconstruction group (19.1%) significantly (P<0.05). The presented data also indicate that hepatic artery resection prolongs survival time comparing with patients undergoing palliative therapy for hilar cholangiocarcinoma. Cox regression analysis indicate that hepatic artery resection and reconstruction is a protective factor compare with palliative therapy (RR=0.38, 95%CI: 0.22-0.67). The significant reason for shorter survival time is a positive correlation between hepatic artery invasion and lymph node metastasis.
Conclusion:Hepatic artery resection and reconstruction has beneficial impact on oncologic long-term outcome in patients with advanced stage hilar cholangiocarcinoma.
