BACKGROUND: Thyroxine (T4) has been positively associated with tumor cell proliferation, while the effect of triiodothyronine (T3) on cell proliferation has not been well-established because it differs according to the type of cell line used. In Mexico, it has been reported that 14.5% of adult women have some type of thyroid dysfunction and abnormalities in thyroid function tests have been observed in a variety of non-thyroidal illnesses, including breast cancer (BC). These abnormalities might change with body mass index (BMI) because thyroid hormones are involved in the regulation of various metabolic pathways and probably by menopausal status because obesity has been negatively associated with BC in premenopausal women and has been positively associated with BC in postmenopausal women...

BACKGROUND: Triple-negative breast cancers (TNBCs) are known for early age at presentation, large tumor sizes, and overall poor prognosis. However, Indian studies are scarce with limited follow-up data. Hence, the present study is aimed at characterizing nonmetastatic TNBC patients in our population and comparing their outcome with non-TNBC subset. METHODOLOGY: This is a retrospective observational study of nonmetastatic breast cancer patients accrued over 14 years...

BACKGROUND: Physical activity is a modifiable lifestyle factor associated with reduced breast cancer risk. Mammographic density is a strong, independent risk factor for breast cancer, and some breast cancer risk factors have been shown to modify mammographic density. However, the effect of physical activity on mammographic density, studied predominantly among Caucasians, has yielded conflicting results. In this study, we examined, in an Asian population, the association between physical activity and mammographic density...

BACKGROUND: The PAM50-based (Prosigna) risk of recurrence (ROR) score and intrinsic subtypes are prognostic for women with high-risk breast cancer. We investigate the predictive ability of Prosigna regarding the effectiveness of cyclophosphamide-based adjuvant chemotherapy in premenopausal patients with high-risk breast cancer. METHODS: Prosigna assays were performed on the NanoString platform in tumors from participants in Danish Breast Cancer Group (DBCG) 77B, a four-arm trial that randomized premenopausal women with high-risk early breast cancer to no systemic treatment, levamisole, oral cyclophosphamide (C) or cyclophosphamide, methotrexate and fluorouracil (CMF)...

Background: Breast cancer is a heterogeneous disease which is divided broadly into luminal, HER2 and basal type based on molecular profiling. Increased body mass index (BMI) has been associated with the risk of developing breast cancer but the association based on molecular subtype remains conflicting. Methods: This was an observational study carried out over a period of 2 years. Nonmetastatic breast cancer patients were evaluated for the tumour subtype based on surrogate markers (ER, PR and HER2)...

Background: 27-hydroxycholesterol (27HC) was the first identified endogenous selective estrogen receptor modulator (SERM); 27HC promoted growth and metastasis in experimental models of estrogen receptor-positive mammary cancer. There are no data on prediagnosis circulating 27HC and breast cancer risk in women. Methods: We conducted a nested case-control study in the well-characterized Heidelberg, Germany, cohort of the European Investigation into Cancer and Nutrition (EPIC) including 530 incident invasive breast cancer cases, each matched to up to two control participants (n = 1036)...

Patients with early estrogen receptor-positive breast cancer are at continuous risk of relapse even after more than 10 years of follow up. Currently, no biomarker that identifies patients for early versus late recurrence, or one that selects patients or tumors for longer versus shorter durations of endocrine therapy (ET) is available and a crucial question is how to properly select patients who could be spared extended ET or those who require it. In the last 20 years more than 40,000 women were enrolled in randomized trials to answer the question of optimal duration of ET...

Despite breast cancer being uncommon in young women, it is still the most frequent cancer diagnosed in women aged 15-39 years, and the leading cause of death in this age group in high-income countries, after accidents and self-injury. The present review summarizes the most recent guidelines and offers an expert perspective on the many challenges associated with treatment of young women with breast cancer. We will especially focus on early breast cancer, exploring the specificities of the diagnostic process, imaging techniques, locoregional and systemic treatments, and the added value of dedicated multidisciplinary teams...
