Gender-related challenges facing oncologists: the results of the ESMO Women for Oncology Committee survey.

Abstract: Background Although women account for a growing proportion of the oncology workforce, there is evidence they are under-represented in leadership roles To gain further insights into this issue and extend understanding of gender challenges, the European Society for Medical Oncology Women for Oncology (W4O) Committee undertook a survey of female and male oncologists in 2016 Design The 2016 W4O questionnaire included questions on (1) Demographics and professional environment, (2) Gender impact on career development, (3) Challenges for career progression and inappropriate behaviour experienced in the workplace, (4) Barriers for gender parity and (5) The gender gap Between July and September 2016, the online survey was available to male and female clinical and academic oncology healthcare professionals in the EU and internationally Results Responses were analysed from 462 oncologists, of whom 767 % were women Of female respondents, 455 % had a managerial or leadership role, compared with 65 % of male respondents (p Conclusions New initiatives are needed to address under-representation of women oncologists in leadership roles, including greater and concrete promotion of work–life balance, development and leadership training for women, and more support for flexible working The fact that over a third of women in the survey had encountered unwanted sexual comments at work is of great concern and must be urgently addressed

FTY720 (fingolimod) for relapsing multiple sclerosis.

Abstract: FTY720 (fingolimod) is a structural analogue of sphingosine, an endogenous lysophospholipid, which targets sphingosine-1-phosphate receptors after biotransformation to FTY720-phosphate. The immunomodulatory properties of this agent are mainly related to its ability to entrap lymphocytes in secondary lymphoid organs, reducing their availability for cell-mediated immune responses. Emerging evidence suggests that FTY720 also exerts direct actions on glial and precursor cells of the CNS which may be relevant for the process of tissue repair after injury. The therapeutic effects of the drug observed in animal models of human multiple sclerosis have provided the experimental basis for its clinical application. A recent Phase II study has demonstrated that oral FTY720 is effective in reducing disease activity in relapsing multiple sclerosis with a favorable adverse-effect profile. These results are awaiting confirmation in the three ongoing Phase III clinical trials evaluating FTY720 for relapsing-remitting multiple sclerosis.

Palbociclib and Trastuzumab in HER2-Positive Advanced Breast Cancer: Results from the Phase II SOLTI-1303 PATRICIA Trial.

Abstract: Purpose: To assess palbociclib in combination with trastuzumab with or without endocrine therapy in patients with HER2-positive advanced breast cancer. Patients and Methods: PATRICIA is a prospective, open-label, multicenter phase II trial. Patients had received 2–4 prior lines of anti-HER2–based regimens. Treatment consisted of palbociclib 200 mg daily for 2 weeks and 1 week off plus trastuzumab. The study was based on a Simon two-stage design comprising three cohorts: estrogen receptor (ER)-negative (cohort A), ER-positive (cohort B1), and ER-positive with letrozole (cohort B2). ER-positive patients were randomized to cohorts B1 or B2. Primary endpoint was progression-free survival rate at 6 months (PFS6). Secondary objectives included safety and evaluation of the PAM50 intrinsic subtypes. Results: Seventy-one patients were recruited (n = 15 in cohort A and 28 in each cohort B). The PFS6 rate in cohorts A, B1, and B2 was 33.3% (5/15), 42.8% (12/28), and 46.4% (13/28), respectively. Regarding safety, grade 1–2 and 3–4 toxicities occurred in 97.7% and 84.4% of patients, respectively. The most common grade 3–4 toxicities were neutropenia (66.4%) and thrombocytopenia (11.3%). Regarding PAM50, 59 (83.1%) tumors were profiled. Luminal disease defined by PAM50 was found independently associated with longer PFS compared with non-luminal disease (10.6 vs. 4.2 months median PFS; adjusted hazard ratio = 0.40; P = 0.003). Conclusions: Palbociclib in combination with trastuzumab is safe and exhibits promising survival outcomes in trastuzumab pretreated ER-positive/HER2-positive advanced breast cancer with a PAM50 Luminal A or B subtype. The enrollment was stopped prematurely, and a new randomized cohort was opened in this population.

Inflammatory cytokines and organ dysfunction associate with the aberrant DNA methylome of monocytes in sepsis.

Abstract: Sepsis, a life-threatening organ dysfunction caused by a dysregulated systemic immune response to infection, associates with reduced responsiveness to subsequent infections. How such tolerance is acquired is not well understood but is known to involve epigenetic and transcriptional dysregulation. Bead arrays were used to compare global DNA methylation changes in patients with sepsis, non-infectious systemic inflammatory response syndrome, and healthy controls. Bioinformatic analyses were performed to dissect functional reprogramming and signaling pathways related to the acquisition of these specific DNA methylation alterations. Finally, in vitro experiments using human monocytes were performed to test the induction of similar DNA methylation reprogramming. Here, we focused on DNA methylation changes associated with sepsis, given their potential role in stabilizing altered phenotypes. Tolerized monocytes from patients with sepsis display changes in their DNA methylomes with respect to those from healthy controls, affecting critical monocyte-related genes. DNA methylation profiles correlate with IL-10 and IL-6 levels, significantly increased in monocytes in sepsis, as well as with the Sequential Organ Failure Assessment score; the observed changes associate with TFs and pathways downstream to toll-like receptors and inflammatory cytokines. In fact, in vitro stimulation of toll-like receptors in monocytes results in similar gains and losses of methylation together with the acquisition of tolerance. We have identified a DNA methylation signature associated with sepsis that is downstream to the response of monocytes to inflammatory signals associated with the acquisition of a tolerized phenotype and organic dysfunction.
