GPC3 and neoplasm: The results showed that GPC3 expression in LUAD samples was significantly correlated with pathologic N (P = 0.01405), pathologic T (P = 0.000227), sex (P = 0.002734), and tumour stage (P = 0.04348), but was not correlated with age, location, years smoked, pathologic M, or radiation therapy (P > 0.05) (Table 3, Fig. 4a).
