HER2 expression estrogen and progesterone receptors and their relationship with clinicalpathological characteristics in Uruguayan patients with breast cancer
Abstract
Introduction: breast cancer, the main cause of death of Uruguayan women, is an heterogeneous disease. Study of the tumoral expression of the Human Epidermal growth factor Receptor-2 (HER2), the estrogen receptor and the progesterone receptor enables the recognition of sub-types with different clinical, and pathological characteristics and evolution.
Objectives: to learn about the HER2, estrogen receptor and progesterone receptor tumoral expression profile and their relationship with clinical-pathological characteristics in Uruguayan patients with breast cancer.
Method: we reviewed the medical record of patients who underwent surgery for invasive breast cancer within a two year period, and we selected those who had determination of estrogen receptor, progesterone receptor and HER2 through immune-histochemestry. We compared the expression profile of these markers with the age at the time of diagnosis, the histological type and degree and the pathological status.
Results: we selected 197 patients with the following characteristics: average age: 55 years old, ductal carcinoma: 85%, histological degree 1-2: 59%; stage I-II: 75%, axillary metastasis: 51%, progesterone receptor/estrogen receptors+ (RE/RP+): 78%, HER2+: 10%. Three subtypes were defined: HER2- RE/RP+ (73%), HER2+ (10%) and triple negative (TN) (17%). Subtypes TN and HER2+ were associated with a greater histological degree (GH) (p<0,05) and the TN with lower age at the time of diagnosis than the HER2-, RE/RP+ subtype.
Conclusions: the percentage of patients with HER2+ subtype invasive breast cancer (10%) is lower than the one reported in others studies. In accordance with previous studies, TN and HER2+ subtypes correlated with less differentiated tumors and TN subtype occurred in younger patients.
