Univariate analysis suggested that BMI <25Kg/m2, CEA ≥10 ng/mL, CA-199 ≥ 40 U/mL, CA-125 ≥ 40 U/mL, NLR ≥2.65, PLR ≥167.8, mGPS of 1 or 2, SII ≥797.7, CALLY-index ≤1.81, and total bilirubin ≥21umol/L, TNM stage III, maximum tumor diameter ≥ 5 cm, multiple tumors, presence of peripheral organ infiltration, presence of lymph node metastasis, and presence of satellite foci were all associated with poorer RFS (p < 0.05). This evidence concerns the gene CEACAM5 and metastatic malignant neoplasm in the lymph nodes.
