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.
