KANKER PAYUDARA WANITA: EKSPRESI RESEPTOR ESTROGEN, RESEPTOR PROGESTERON DAN HER-2 Udadi Sadhana*) SUMMARY Recently, the incidence of breast cancer is increasing every year. There were 3 etiologic factors of breast cancer; genetics, hormonal imbalance, and environment exposure. The normal breast mucous epithelial has estrogen receptor (ER). The breast cancer cell secretes epithelial growth factors/transformation growth factors α, platelet derived growth factor (PDGF) and growth inhibitors (TGF-β). In breast cancer, ER may high, moderate or none. The cancer with high ER is better than moderate as well as nothing. ER stimulates the expression of gene. Progesterone receptor (PR) also plays important role in controlling ER gene. About 75% primary breast cancer expresses ER, and more than a half also expresses PR. ER status is a strong predictor in the response of endocrine therapy of breast cancer. Key Words: estrogen receptor, progesterone receptor, HER-2, breast cancer RINGKASAN Saat ini, kanker payudara merupakan keganasan yang banyak diderita wanita dengan peningkatan insidensi setiap tahunnya.
