Progression-free survival of patients with para-aortic lymph node resection. a Progression-free survival of patients with para-aortic lymph node (PALN) resection (n = 67). Patient subgroups with PALN metastasis (PALN+, n = 7) and without PALN metastasis (PALN−, n = 60) were plotted. b Progression-free survival of patients with PALN resection separated into PALN+ (n = 7), PALN− pN0 (n = 29), and PALN− pN1 (n = 31) subgroups according to the regional lymph node status
