Figure 3 The overall survival curve shows that 3- and 5-year overall survival rates were 74. 9% and 60.5%, respectively, in the LAP group and 62.4% and 46.5%, respectively, in the OPEN group. There was no significant difference between the LAP and OPEN groups (P = 0.060).

Figure 4 The disease-free survival curve shows that the 3- and 5-year disease-free survival rates were 68. 0% and 57.3%, respectively, in the LAP group and 55.8% and 39.8%, respectively, in the OPEN group. There was no significant difference between the LAP and OPEN groups (P = 0.053).
