A study led by UCLA researchers found that adding ribociclib, a targeted therapy drug, to standard hormone therapy significantly improves overall survival in postmenopausal women with advanced hormone-receptor positive/HER2- breast cancer, one of the most common types of the disease.The findings also show the combination treatment is beneficial at the time of recurrence and should become a first-line option in postmenopausal women with HR+/HER2- advanced breast cancer.The study was published today in the New England Journal of Medicine and presented earlier this year at the European Society for Medical Oncology Congress in...

AbstractPurpose of reviewEarly detection and improved treatment in breast cancer have resulted in an increased number of survivors. Cardiovascular disease now remains an important cause for morbidity and mortality in this population. There is a growing gap in the knowledge about the optimal long-term cardiovascular management of this population.FindingsBreast cancer and cardiovascular disease share a number of common risk factors. Different breast cancer treatment modalities, including anthracyclines, radiation, and hormonal therapy, can act in synergy with preexisting and/or new cardiovascular risk factors to result in si...

ConclusionsIn this cohort of young women, population-based cancer registry data on chemotherapy receipt was reasonably accurate and complete in comparison with insurance claims. Radiation and hormone therapy appeared to be less complete.

Abstract The addition of adjuvant chemotherapy to hormonal therapy is often considered questionable in patients with estrogen receptor-positive early breast cancer. Low risk of disease relapse after endocrine treatment alone and/or a low sensitivity to chemotherapy are reasons behind not all patients benefit from chemotherapy. Most of patients could be exposed to unnecessary treatment-related adverse events and health care costs when treatment decision-making is based only on classical clinical histological features. Gene expression profile has been developed to refine physician decision-making process and to tayl...

This study aims to evaluate the antitumour activity of tamoxifen (TAM), a major agent of hormonal therapy for breast cancer, in preclinical GBC model. Quantitative real-time PCR was used to investigate mRNA levels. Protein expression was measured by immunohistochemistry and Western blot. Glycolytic levels were measured by glucose consumption and lactic acid measurement. The antitumour activity of TAM alone or with cisplatin was examined with CCK8 assay, colony formation, flow cytometry and in vivo models. The results revealed that ERÉ‘ expression was higher in GBC tissues and predicted poor clinical outcomes. TAM was showe...

She suddenly developed a right femoral shaft fracture during treatment. Her femoral fracture had a beaking sign on radiogram. Given this finding, her fracture was ultimately diagnosed as atypical femoral fracture (AFF). In this case, it was difficult to recognize the differ...

CONCLUSION: Our nationwide retrospective analysis revealed that pregnancy after BC diagnosis was associated with lower mortality than that of nonpregnant patients with BC at a similar age, year at diagnosis, and clinical characteristics. IMPLICATIONS FOR PRACTICE: This article provides high-level evidence based on an Asian population for pregnancy counseling after a breast cancer diagnosis, including for patients with estrogen receptor-positive cancers. The study also revealed the optimal time for patients who would like to become pregnant after breast cancer. PMID: 31767794 [PubMed - as supplied by publisher]

Abstract Experimental and clinical evidence demonstrate that progesterone hormone and its nuclear receptor, the Progesterone Receptor (PR), play critical role in controlling mammary gland tumorigenesis and breast cancer development. Hormonal therapy (Tomaxifen) is the frontline treatment for hormone-dependent breast cancers .Progesterone hormone induces its action on the target cells by binding with its Progesterone receptor (PgR) therefore any genetic variations, which might induce alienation in the progesterone receptor, can result to an increased susceptibility to gynecological cancers. Alu insertion (PROGINS) ...
