Figure 1. (A) Postoperative recurrence-free survival. The 5-y RFS of patients in the “ATVAC” group (n = 42) was 35.7%, with a median RFS of 24.5 mo. The 5-y RFS of patients in the “Operation alone” group (n = 52) was 11.5%, with a median RFS of 12.6 mo (P = 0.011). (B) Postoperative overall survival. The 5-y OS of patients in the “ATVAC” group was 64.3%, with a median OS of 97.7 mo. The 5-y OS of patients in the “Operation alone” group was 44.2%, with a median OS was 41.0 mo (P = 0.029).
