A univariate Cox proportion hazards model showed that postoperative adjuvant therapy, age, and lymph node metastasis were associated with prognosis (P < .05), but gender, tumor location, tumor histological morphology, pathological type, the presence of vascular tumor emboli or nerve invasion, the number of lymph node dissections, the degree of differentiation, the Syn/CgA staining results, and TNM staging were not associated with prognosis. Here, CGA is linked to vascular neoplasm.
