Tamoxifen and the uterus [PDF]
The effects of tamoxifen on the endometrium have caused concern since the late 1980s,1,2 and clear evidence of endometrial changes has now emerged from three studies in postmenopausal women - one case-control study of breast cancer3 and two randomised controlled trials, one in women with early breast cancer4 and one in healthy women with a family ...

Microarray analysis of tamoxifen resistance in breast cancer. [PDF]
PhDTamoxifen remains a widely used hormone therapy for pre and postmenopausal women with hormone receptor positive breast cancer in both adjuvant and metastatic disease settings. Resistance to this well tolerated and cost-effective drug limits its use.

Molecular gene expression and genome wide profiling in tamoxifen-resistant breast cancer. [PDF]
PhDOestrogen receptor positive (ER+) breast cancers (BC) are heterogeneous in both their clinical behaviour and response to therapy. The ER and Progesterone (PgR) are currently the best predictors of response to the anti-oestrogen tamoxifen, yet up to 40%

Italian randomized trial among womenwith histerectomy: tamoxifen and hormone-dependent breast cancer in hight-risk women [PDF]
Tamoxifen improves outcome in women with breast cancer and reduces the incidence of estrogen receptor-positive (ER+) breast tumors in prevention trials. Tamoxifen use is associated with an increased risk of potentially serious adverse events, principally

Background The cytochrome P450 (CYP) enzymes 2C19, 2D6, and 3A5 are responsible for converting the selective estrogen receptor modulator (SERM), tamoxifen to its active metabolites 4-hydroxy-tamoxifen (4OHtam) and 4-hydroxy-N-demethyltamoxifen (4OHNDtam,

Combination treatment of tamoxifen with risperidone in breast cancer.
Tamoxifen has long been used and still is the most commonly used endocrine therapy for treatment of both early and advanced estrogen receptor-positive breast cancer in pre- and post-menopause women. Tamoxifen exerts its cytotoxic effect primarily through

NR4A1 Regulates Tamoxifen Resistance by Suppressing ERK Signaling in ER-Positive Breast Cancer
Endocrine therapy is used to treat estrogen receptor (ER)-positive breast cancer. Tamoxifen is effective against this cancer subtype. Nonetheless, approximately 30% of patients treated with tamoxifen acquire resistance, resulting in therapeutic ...
