Survival curves according to the postoperative LCR of patients with pre-LCR^High (a) and those with pre-LCR^L°^w (b). The 5 year survival among patients with pre-LCR^High and post-LCR^High and among those with pre-LCR^High and post-LCR^L°^w did not differ significantly (84.8% vs. 81.2%, p = 0.205). On the contrary, the 5 year survival rate was significantly worse in patients with pre-LCR^L°^w and post-LCR^L°^w than in those with pre-LCR^L°^w and post-LCR.^High (52.0% vs. 81.6%, p < 0.0001)
