Survival curves in patients with no metastases (N0 patients), patients with skip metastasis, and patients without skip metastasis according to different criteria. (A) JSED (N0 vs. skip (+), P = 0.047; N0 vs. skip (−), P = 0.031; skip (+) vs. skip (−), P = 0.302). (B) Survival curves in N0 patients, patients with skip metastasis, and patients without skip metastasis according to AJCC (N0 vs. skip (+), P = 0.094); N0 vs. skip (−), P = 0.004; skip (+) vs. skip (−), P = 0.302). (C) Survival curves in N0 patients, patients with skip metastasis, and patients without skip metastasis according to the anatomical compartment (N0 vs. skip (+), P = 0.74; N0 vs. skip (−), P = 0.002; skip (+) vs. skip (−), P = 0.180).
