TSPAN3 and non-small cell lung carcinoma: Statistical analysis suggested that high TSPAN3 expression in NSCLC was positively associated with poor differentiation, lymph node involvement, and advanced pathological tumor-node-metastasis stage (P = 0.006, 0.006, 0.011, respectively; Table 1) but showed no significant association with sex, age, and histological type (P > 0.05; Table 1).
