PURPOSE We investigated time to pregnancy, efficacy and safety of fertility preservation, and assisted reproductive technologies (ARTs) in women with early hormone receptor–positive breast cancer (BC) desiring future pregnancy. PATIENTS AND METHODS POSITIVE is an international, single-arm, prospective trial, in which 518 women temporarily interrup...

Background: Despite the progressive de-escalation of breast cancer (BC) surgery, mastectomy rates remain around 30-40%. Furthermore, up to 1/3 of BC patients undergo a contralateral risk-reducing mastectomy and around 40% of mutation carriers choose a bilateral intervention. To date, immediate breast reconstruction (IBR) with implants is the most c...

PURPOSE The OlympiA randomized phase III trial compared 1 year of olaparib (OL) or placebo (PL) as adjuvant therapy in patients with germline BRCA1/2, high-risk human epidermal growth factor receptor 2–negative early breast cancer after completing (neo)adjuvant chemotherapy ([N]ACT), surgery, and radiotherapy. The patient-reported outcome primary h...

After a diagnosis of unilateral breast cancer, increasing numbers of patients are requesting contralateral prophylactic mastectomy (CPM), the surgical removal of the healthy breast after diagnosis of unilateral breast cancer. It is important for the community of breast cancer specialists to provide meaningful guidance to women considering CPM. This...

Background: The randomized, double-blind OlympiA trial compared one year of the oral poly(adenosine diphosphate-ribose) polymerase) inhibitor, olaparib, to matching placebo as adjuvant therapy for patients with pathogenic or likely pathogenic variants in germline BRCA1 or BRCA2 (gBRCA1/2pv) and high-risk, human epidermal growth factor receptor 2 (...

Significant progress has been achieved in human health in the European Union in recent years. New medicines, vaccines, and treatments have been developed to tackle some of the leading causes of disease and life-threatening illnesses. It is clear that investment in research and development (R&D) for innovative medicines and treatments is essential f...

The 5th International Consensus Symposium for Breast Cancer in Young Women (BCY5) took place virtually in October 2020, organized by the European School of Oncology (ESO) and the European Society of Medical Oncology (ESMO). Consensus recommendations for the management of breast cancer in young women were updated from BCY4 with incorporation of new...

Background The landscape of clinical trials testing risk-adapted modulations of cancer treatments is complex. Multiple trial designs, endpoints, and thresholds for non-inferiority have been used; however, no consensus or convention has ever been agreed to categorise biomarkers useful to inform the treatment intensity modulation of cancer treatments...

Background: The primary results from the OlympiA trial were recently reported (NEJM, 2021) after an interim analysis demonstrated statistically significant invasive disease-free survival (DFS) benefit from 1 year of olaparib (OL) vs. placebo (PL) after 2.5 yrs median follow-up. Although there were fewer deaths with OL than PL, overall survival (OS)...

Breast cancer is an increasing global health, gender, socioeconomic, and equity challenge. In 2020, 2·3 million women were diagnosed with breast cancer and there were 685 000 deaths worldwide.1 Not only is breast cancer the highest incident cancer globally, but it is also the most prevalent, causing more disability-adjusted life-years lost than any...

Background Trastuzumab targets the extracellular domain of the HER2 protein. Adding trastuzumab to chemotherapy for patients with early-stage, HER2-positive breast cancer reduces the risk of recurrence and death, but is associated with cardiac toxicity. We investigated the long-term benefits and risks of adjuvant trastuzumab on breast cancer recurr...

Purpose We aimed to assess patients’ and physicians’ perspectives on wider implementation of telemedicine in radiation oncology practice, disrupted by the novel coronavirus disease 2019 (COVID-19). Methods Quantitative questionnaires were prepared and distributed between May 27 and June 11, 2020. A 29-question survey targeting patients with cancer...

The 4th International Consensus Conference for Breast Cancer in Young Women (BCY4) took place in October 2018, in Lugano, Switzerland, organized by the European School of Oncology (ESO) and the European Society of Medical Oncology (ESMO). Consensus recommendations for the management of breast cancer in young women were updated from BCY3 with incorp...

Liver development and function are dependent on specific gene expression profile. Many genes in the liver are differentially expressed between females and males and these sex differences are thought to be at least partially influenced by sex specific patterns of growth hormone secretion. The aim of this study was to examine whether sex chromosomes...

Significance statement: Fezf1 gene has been identified in the present study as a regulator of female sexual behavior in mice. Regulation of the female sexual behavior could be through the regulation of estrogen receptor alpha expression in the ventromedial nucleus of the hypothalamus, as the expression of this receptor was reduced in mice with dow...

The 3rd International Consensus Conference for Breast Cancer in Young Women (BCY3) took place in November 2016, in Lugano, Switzerland organized by the European School of Oncology (ESO) and the European Society of Medical Oncologists (ESMO). Consensus recommendations for the management of breast cancer in young women were updated from BCY2 with inc...

Steroidogenic factor 1 (SF-1), officially designated NR5A1, is essential for gonadal and adrenal development and for the normal structure of the ventromedial hypothalamus, as demonstrated by SF-1 knockout mice (SF-1 KO), but much less is known about the possible effects of haploinsufficiency of the SF-1 gene. In the present study, maternal behavior...

Abstract The presence of steroidogenic enzymes in the brain suggests de novo synthesis of steroid hormones in the brain. The current study was designed to determine the developmental profiles of cytochrome p450 aromatase (cyp19), 17β-hydroxysteroid dehydrogenase (17β-HSD), 5α-reductase type I and 3α-hydroxysteroid dehydrogenase (3α-HSD) mRNA expres...

Female receptivity including the immobile hormone-dependent lordosis posture is essential for successful reproduction in rodents. It is well documented that lordosis is organized during the perinatal period when the actions of androgens decrease the males' ability to display this behavior in adulthood. Conversely the absence of androgens, and the p...

The brain begins its life as neither male nor female and waits to be impacted by differences of genetic and hormonal actions that continue throughout the lifetime of an organism. Many differences have been described in the brain between sexes of a variety of species, ranging from amphibians and reptiles through birds and mammals, including humans....
