Poor DFS was significantly associated with CCI ≥ 3, albumin <3.9 g/dL, prognostic nutritional index < 40, nonadenocarcinoma cancer, lymph node metastasis, solid component diameter > 20 mm, and postoperative complications (all P < 0.05, log‐rank test). This evidence concerns the gene ALB and metastatic malignant neoplasm in the lymph nodes.
