BRAIN METASTASIS, TUMOR, PRIMARY TUMOR, LUNG METASTASIS, BONE METASTASIS, REGRESSION, LIVER METASTASIS
Firstly, one-way COX regression analysis for age, race, gender, tumor primary site, tumor size, TNM stage of the 8th edition of AJCC, serum carcinoembryonic antigen, nerve invasion, lymph node metastasis, liver metastasis, lung metastasis, bone metastasis, and brain metastasis were performed. Several factors, including primary tumor site, tumor size, ethnicity, serum carcinoembryonic antigen, nerve invasion, lymph node metastasis, liver metastasis, lung metastasis, bone metastasis, and brain metastasis, were significantly associated with COCA prognosis (Univariate and multivariate analyses of factors linked to COCA prognosis*
