Expression of androgen receptor and its regulatory molecule Lin28 in non-luminal subtype breast cancer.

Androgen receptor (AR) was associated with favourable outcome in luminal breast cancer. However, the role of AR in non-luminal breast cancer remains inconclusive. The aim of the present study was to evaluate the clinical significance of the AR and its regulatory pathway in non-luminal subtypes of breast cancer.

Survival outcome of combined GnRH agonist and tamoxifen is comparable to that of sequential adriamycin and cyclophosphamide chemotherapy plus tamoxifen in premenopausal patients with early breast cancer.

Survival outcome of ovarian suppression plus tamoxifen has been shown to be comparable with chemotherapy in premenopausal women; however, there are a few previous studies that compared this treatment to the current standard adriamycin and cyclophosphamide (AC) regimen. The aim of the present study was to compare the survival outcome of gonadotropin-releasing hormone (GnRH) agonist plus tamoxifen (GnRH-TAM) and chemotherapy AC plus tamoxifen (AC-TAM) in premenopausal patients with early breast cancer who were hormone receptor-positive. Premenopausal patients with early breast cancer who were treated at The Siriraj Hospital between January 2005 and December 2015 were retrospectively recruited.
