BTG3 expression was higher in gastric intestinal-type than diffuse-type carcinomas, G1 than G3 carcinomas (p < 0.05), in female than male cancer patients, T1-2 than T3-4, and adenocarcinoma than squamous cell carcinoma of lung cancer (p < 0.05), in invasive ductal than lobular carcinoma, N0 than N1 and N3, TNBC (triple-negative breast cancer) than luminal and Her2+, and Her2+ than luminal cancer of breast cancer (p < 0.05), and G3 than G2 ovarian carcinoma (p < 0.05). This evidence concerns the gene ERBB2 and adenocarcinoma.
