Purpose: Mesothelin (MSLN) is highly expressed in high grade serous/ endometrioid ovarian cancers (HGOC). Anetumab ravtansine (AR) is an antibody drug conjugate directed at MSLN antigen with a tubulin polymerization inhibitor. We assessed safety, activity and pharmacokinetics of the combination AR/bevacizumab (Bev) (ARB) versus weekly paclitaxel (wP)/Bev (PB) in patients with platinum resistant/refractory HGOC (prrHGOC).

Paradoxically, cancer-initiating events also facilitate transcription of repetitive elements. Contributions of repetitive element transcription towards cancer initiation, and the mechanisms by which cancer cells evade lethal viral mimicry responses during tumor initiation remain poorly understood.

We used data from SOLO2/ENGOT-Ov21 to evaluate AEs reported in the placebo arm and to explore their longitudinal trajectories.
Methods: SOLO2/ENGOT-Ov21 (NCT01874353) randomly assigned 295 PSROC participants with a BRCA1/2 mutation to maintenance olaparib tablets (N = 196) or matching placebo (N = 99).
Findings from clinical trials have led to advancement of care for patients with gynecologic malignancies. However, restrictive inclusion of patients into trials has been widely criticized for inadequate representation of the real-world population. Ideally, patients enrolled in clinical trials should represent a broader population to enhance external validity and facilitate translation of outcomes across all relevant groups.

This integrated safety summary sought to characterize the safety profile of MIRV monotherapy in participants with FRα-expressing recurrent EOC.
Methods: Safety data were retrospectively analyzed from 4 clinical studies (phase 1 trial [NCT01609556], phase 3 FORWARD I [NCT02631876], phase 2 SORAYA [NCT04296890], phase 3 MIRASOL [NCT04209855]) that evaluated participants with FRα-expressing recurrent EOC who received ≥1 dose of MIRV 6 mg/kg adjusted ideal body weight every 3 weeks.
Objective: There are no data, and thus no consensus, on the optimal duration of poly(ADP-ribose) polymerase (PARP) inhibitor maintenance therapy for exceptional responders (here defined as progression-free for 5 years or longer) with platinum sensitive recurrent ovarian cancer. The current licence is to continue PARP inhibitors until progression or toxicity; however, international practice varies considerably. The risks of late progression and late-onset myeloid malignancies, defined as occurring beyond 5 years of PARP inhibition, are unknown.

Methods: PubMed, Embase, and Cochrane databases were searched (from database inception until February 2022), and prospective ovarian cancer studies (experimental or observational) that incorporated patient reported outcomes, including quality of life, were included. The primary objective was to assess the ratio of studies incorporating real-time use of patient reported outcomes among those studies performing patient reported outcomes.
Background: Different factors have been associated with changes in antimicrobial consumption rates in Ireland, however the relationship between socio-economic deprivation and antimicrobial consumption has not been explored. The presented ecological analysis explores the temporal and geographical variation in outpatient antimicrobial consumption and socio-economic deprivation in Ireland from January 2015 to March 2022.
Method: Deprivation index (DI) was used as a socio-economic proxy.
PARP inhibitor (PARPi) therapy has transformed outcomes for patients with homologous recombination DNA repair (HRR) deficient ovarian cancers, for example those with BRCA1 or BRCA2 gene defects. Unfortunately, PARPi resistance is common. Multiple resistance mechanisms have been described, including secondary mutations that restore the HR gene reading frame.

SPEs arise when our existing internal models of limb-environment properties and interactions become miscalibrated due to changes in the environment, while TPEs occur when environmental perturbations hinder achievement of task goals. The precise mechanisms employed by the sensorimotor system to learn from such limb- and task-related errors and improve future performance are not comprehensively understood.

Methods: Analysis of the prespecified, exploratory subgroup of patients with TP53wt EC from the phase 3 SIENDO study was performed. Progression-free survival (PFS) benefit in patients with TP53wt EC and across other patient subgroups were exploratory endpoints.
Objectives: Implementation of an interprofessional program at Princess Margaret Cancer Centre, including nurse-led proactive calls to support patients with gynecologic cancers with malignant bowel obstruction, demonstrated improved outcomes compared with historical controls. The aim of the study was to convert the proactive calls into an electronic monitoring program to assess it's feasibility and scalability in patients with gynecologic cancers with or at risk of malignant bowel obstruction.
Methods: 'My Bowels on Track' smartphone application included weekly/biweekly electronic patient-reported outcomes (PROs), educational materials, and a secure messaging system.
