Univariate and multivariate Cox analyses were used for the assessment of the correlation between clinical features (including sex, age, ApoA-I levels, NLR, cT classification, cN classification, degree of tumor differentiation, number of liver metastases, type of liver metastases, pathological type, KPS scores, primary surgery, chemotherapy, targeted therapy, topical treatment, metastasis surgery, and tumor location) and overall survival (OS). Here, APOA1 is linked to metastasis.
