Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in women.To meet PCOS criteria,women must have a combination of hyperandrogenism,anovulation and ultrasound findings.Almost 10% of all reproductive age women worldwide show signs of PCOS.Although women often seek care for gynecological or body image concerns,many PCOS women are at risk for metabolic syndrome (MS).Many of the metabolic consequences are overlooked and un-dertreated by physicians because these patients tend to be young,reproductive age women.MS and obesity coexist commonly with PCOS.These young women are predisposed to glucose abnormalities and ulti-mately diabetes mellitus,dyslipidemia and eventually cardiovascular disease.Bariatric surgery can be an ef-fective means of weight loss in PCOS women.Surgical techniques have become safer and less invasive over time and have been found to be effective in achieving significant weight loss.Surgical options have also in-creased,giving patients more choices.Bariatric surgery may prevent or reverse metabolic syndrome.Bariatric surgery may also have reproductive benefits in PCOS patients.Although bariatric surgery has historically been performed in older,reproductive aged women,it has recently gained favor in adolescents as well.This is of particular importance due to the prevalence of both PCOS and MS in adolescents.Treatment of PCOS and MS certainly requires a combination of medical therapy,psychological support and lifestyle modifications.These treatments are difficult and often frustrating for pa-tients and physicians.Bariatric surgery can be effective in achieving significant weight loss,restoration of the hypothalamic pituitary axis,reduction of cardiovascular risk and even in improving pregnancy outcomes.Ulti-mately,bariatric surgery should be considered part of the treatment in PCOS women,especially in those with MS. 相似文献

Poly (ADP-ribose) polymerase (PARP) inhibitors, a novel class of drugs that target tumors with DNA repair defects, have received
tremendous enthusiasm. Early preclinical studies identified BRCA1 and BRCA2 tumors to be highly sensitive to PARP inhibitors as a result of homologous recombination defect. Based on this premise, PARP
inhibitors have been tested in early phase clinical trials as a single agent in BRCA1 or BRCA2 mutation carriers and in combination with chemotherapy in triple-negative breast cancer patients. For high-risk populations,
use of PARP inhibition as a prevention agent has been postulated, but no robust preclinical or clinical studies exist yet.
We review the preclinical and clinical studies in treatment of breast cancer and rationale for use of PARP inhibitors as a
prevention agent for high-risk populations. Of significance, PARP inhibitors vary significantly in mechanism of action, dosing
intervals, and toxicities, which are highlighted in this review. 相似文献

Antiangiogenic therapy is a promising approach for the treatment of breast cancer. In practice, however, only a subset of patients who receive antiangiogenic drugs demonstrate a significant response. A key challenge, therefore, is to discover biomarkers that are predictive of response to antiangiogenic therapy. To address this issue, we have designed a window-of-opportunity study in which bevacizumab is administered as a short-term first-line treatment to primary breast cancer patients. Central to our approach is the use of a detailed pharmacodynamic assessment, consisting of pre- and post-bevacizumab multi-parametric magnetic resonance imaging scans and core biopsies for exon array gene expression analysis. Here, we illustrate three intrinsic patterns of response to bevacizumab and discuss the molecular mechanisms that may underpin each. Our results illustrate how the combination of dynamic imaging data and gene expression profiles can guide the development of biomarkers for predicting response to antiangiogenic therapy. 相似文献
