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

Figure 2 Survival curves of patients in the palliative resection and lymph node dissection (+) lymph node (+) groups. There are significant differences between the palliative resection group and patients with lymph node (LN) involvement and a solitary tumor (P = 0.013). There are no significant differences between the palliative resection group and patients with LN involvement and multiple tumors (P = 0.744).
