The number of TAMs was related to the histological stage of oral cancer and the pathological type of oral cancer (P > 0.05), but not to the patient's gender, age, or duration of oral cancer (P < 0.05), and the expression of VEGF-C was related to the histological stage of oral cancer (P < 0.05), but not to the patient's gender, age, duration of oral cancer, or pathological type of oral cancer (P > 0.05, Table 4). This evidence concerns the gene VEGFC and lip and oral cavity carcinoma.
