Oncologic Impact of Lymph Node Dissection for Intrahepatic Cholangiocarcinoma : a Propensity Score-Matched Study

BACKGROUND: Intrahepatic cholangiocarcinoma is a malignancy of the intrahepatic biliary tree. Although surgical resection is the mainstay of treatment for this tumor, the impact of lymph node dissection during hepatectomy is controversial. In this study, we evaluated the impact of lymph node dissection during surgical resection for intrahepatic cholangiocarcinoma.

METHODS: Records from 170 patients who underwent radical hepatectomy for intrahepatic cholangiocarcinoma from January 2000 to December 2014 were retrospectively reviewed. Twenty-two patients who underwent R1 resection or had distant metastasis at the time of surgery were excluded. Using propensity score matching (matched factors: differentiation, lymphovascular invasion, perineural invasion, and T stage), the patients were divided into two groups: no dissection (n = 34) or lymph node dissection (n = 34). Disease-free survival and overall survival were compared between groups.

RESULTS: There was a marginally significant difference between the two groups with respect to the disease-free survival (no dissection vs. lymph node dissection: 20.0 [4.2-35.8] months vs. 64.0 [27.3-120.8] months, p = 0.077). Overall survival was significantly longer in the lymph node dissection group (no dissection vs. lymph node dissection: 44.0 [31.1-56.9] months vs. 90.0 [51.1-158.9] months, p = 0.027).

CONCLUSION: Radical surgery including an adequate lymph node dissection area and suitable harvested lymph nodes appears to improve oncologic outcomes for intrahepatic cholangiocarcinoma.
