Routine lymph node dissection may be not suitable for all intrahepatic cholangiocarcinoma patients: Results of a monocentric series

Figure 1 Overall survival and recurrence-free survival curves of intrahepatic cholangiocarcinoma patients without lymph node involvement. A: Survival curves of patients in the lymph node dissection (LND) (-) and LND (+) LN (-) groups. There is no significant survival difference between the two groups (P = 0.822). The censored represented the cases who were still alive at the endpoint; B: Recurrence-free survival curve of patients in LND (-) and LND (+) LN (-) groups. There is no significant survival difference between the two groups (P = 0.970). The censored represented the cases who were still alive at the endpoint or died for other reasons instead of tumor recurrence.
