Objective: We sought to describe the association between genomic instability score (GIS) and progression-free survival (PFS) and overall survival (OS) in patients with newly diagnosed, non-BRCA1/2 ovarian cancer.

Methods: Homologous recombinant deficiency (HRD) status was based on a cutoff of ≥42 GIS; patients <42 were categorized with homologous recombination proficiency (HRP). We collected type and duration of maintenance therapy, among other variables, and built a multivariate model with landmark analysis at 6 months from baseline and applied it for time-dependent variables.

Introduction: Homologous recombination deficiency (HRD) testing is used to determine the appropriateness of poly ADP-ribose polymerase inhibitors for patients with epithelial ovarian cancer and no germline/somatic BRCA1/2 alterations. Myriad MyChoice CDx reports a genomic instability score (GIS) to quantify the level of HRD, with a positive score defined as ≥42. The authors sought to define factors associated with obtaining an inconclusive HRD test result.

Article Synopsis
  • - The study investigates the expression of folate receptor alpha (FRα) in ovarian low-grade serous carcinoma (LGSC) and its potential as a therapeutic target for treatment with mirvetuximab soravtansine.
  • - Out of 89 LGSC samples examined, 40% showed high FRα expression, with no significant links found between FRα levels and patient age, race, or survival outcomes.
  • - The presence of high FRα expression was more common in LGSCs without genetic alterations in the MAPK pathway, indicating that FRα testing could be useful for selecting patients for targeted therapies.

Background: A positive urine fentanyl toxicology test may have considerable consequences for peripartum individuals, yet the extent to which fentanyl administration in a labor epidural may lead to such a positive test is poorly characterized.

Objective: This study aimed to quantify the extent to which neuraxial fentanyl in labor neuraxial analgesia can lead to a positive peripartum maternal or neonatal urine toxicology test.

Study Design: We performed a prospective cohort study of pregnant participants planning a vaginal delivery with neuraxial analgesia.

Background: Expression of angiotensin-converting enzyme 2 (ACE2) and type II transmembrane serine protease (TMPRSS2), host molecules required for viral entry, may underlie sex differences in vulnerability to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We investigated whether placental ACE2 and TMPRSS2 expression vary by fetal sex in the presence of maternal SARS-CoV-2 infection.

Methods: Placental ACE2 and TMPRSS2 expression was quantified by quantitative reverse transcription polymerase chain reaction (RT-PCR) and by Western blot in 68 pregnant women (38 SARS-CoV-2 positive, 30 SARS-CoV-2 negative) delivering at Mass General Brigham from April to June 2020.

Objective: The objective of this study was to determine the proportion of patients with a pre-invasive endometrial lesion who meet Mayo criteria for lymph node dissection on final pathology to determine if the use of sentinel lymph node biopsy in patients with pre-invasive lesions would be warranted.

Methods: All women who underwent hysterectomy for a pre-invasive endometrial lesion (atypical hyperplasia or endometrial intra-epithelial neoplasia) between 2009 and 2019 were included for analysis. Relevant statistical tests were utilized to test the associations between patient, operative, and pathologic characteristics.

Background: Adjuvant therapy in early-stage endometrial cancer has not shown a clear overall survival benefit, and hence, patient selection remains crucial.

Objective: To determine whether women with high-intermediate risk, early-stage endometrial cancer with lymphovascular space invasion particularly benefit from adjuvant treatment in improving oncologic outcomes.

Methods: A multi-center retrospective study was conducted in women with stage IA, IB, and II endometrial cancer with lymphovascular space invasion who met criteria for high-intermediate risk by Gynecologic Oncology Group (GOG) 99.
