Prognosis after resection for hepatitis B virus-associated intrahepatic cholangiocarcinoma

Figure 1 Overall survival and disease-free survival curves of the 85 hepatitis B virus-associated intrahepatic cholangiocarcinoma patients after curative resection. The median overall survival was 25 mo. The median disease-free survival was 17.9 mo.

Figure 2 Overall survival curves of patients in lymph node dissection (-), lymph node (-) and lymph node (+) groups. There was no statistically significant difference in OS between the lymph node dissection (LND) (-) and LN (-) groups (P = 0.729). There were significant differences between LN (-) and LN (+) groups (P = 0.033). A statistically significant difference between LND (-) and LN (+) groups was observed (P = 0.004). LND: Lymph node dissection; LN: Lymph node.

Figure 3 Overall survival curves of hepatitis B virus-associated intrahepatic cholangiocarcinoma patients undergoing sampling lymph node sampling and regional lymph node dissection. There were no significant differences between the two groups (P = 0.089). LND: Lymph node dissection; LN: Lymph node.

Figure 4 Overall survival curves of hepatitis B virus-associated intrahepatic cholangiocarcinoma patients without lymph node involvement. There was no survival difference between lymph node sampling and regional LND groups (P = 0.182). There was no statistically significant difference in overall survival between LND (-) and lymph node sampling groups (P = 0.709). There were also no significant differences between LND (-) and regional LND groups (P = 0.309). LND: Lymph node dissection.
