Objective: We sought to describe the oncologic outcomes of isolated serous tubal intraepithelial carcinomas compared to an intraepithelial carcinoma found concurrently with microscopic high-grade serous carcinoma among patients with hereditary predisposition to ovarian cancer who underwent risk-reducing surgery.

Methods: We conducted a retrospective analysis of 32 high-risk patients with or pathogenic variants who were diagnosed with either isolated serous tubal intraepithelial carcinoma or concurrent serous tubal intraepithelial carcinoma and microscopic high-grade serous carcinoma following risk-reducing surgery between January 2006 and December 2023. Our population included patients who underwent surgery at our institution as well as those who had surgery elsewhere, but sought second opinions, follow-up care, or treatment at our institution.

Objectives: To compare perioperative outcomes in patients undergoing pelvic exenteration for gynecologic malignancies before and after implementation of Enhanced Recovery After Surgery (ERAS) protocols.

Methods: We performed an institutional retrospective cohort study of patients undergoing pelvic exenteration for gynecologic malignancies before (1/1/2006-12/30/2014) and after (1/1/2015-6/30/2023) ERAS implementation. We described ERAS compliance rates.

Objective: The impact of adjuvant pelvic radiation therapy on the rate and location of recurrences was evaluated in patients with early-stage (IA1-IB2) neuroendocrine cervical carcinoma who underwent prior conization or polypectomy with no residual disease and negative nodes in the subsequent upfront radical hysterectomy specimen. As a secondary objective, disease-free and overall survival were analyzed.

Methods: We searched the Neuroendocrine Cervical Tumor Registry (NeCTuR) to identify patients with clinical early-stage neuroendocrine cervical carcinoma with no residual disease in the specimen from upfront radical surgery and negative nodes.

Background: Recurrent high-grade neuroendocrine cervical cancer has a very poor prognosis and limited active treatment options.

Objective: This study aimed to evaluate the efficacy of the 3-drug regimen of topotecan, paclitaxel, and bevacizumab in women with recurrent high-grade neuroendocrine cervical cancer.

Study Design: This retrospective cohort study used data from the Neuroendocrine Cervical Tumor Registry (NeCTuR), which include data abstracted directly from medical records of women diagnosed with high-grade neuroendocrine carcinoma of the cervix from English- and Spanish-speaking countries.

Objective: To evaluate the survival impact of adding definitive pelvic radiation therapy (RT) to chemotherapy among patients with stage IVB neuroendocrine cervical carcinoma (NECC).

Methods: We retrospectively studied patients with FIGO 2018 stage IVB NECC diagnosed during 1998-2020 who received chemotherapy with or without definitive whole pelvic RT (concurrent or sequential). Demographic, oncologic, and treatment characteristics were summarized.

Objective: Patients with early-stage, high-grade neuroendocrine cervical carcinoma typically undergo radical hysterectomy with pelvic lymphadenectomy followed by adjuvant radiotherapy and/or chemotherapy. To explore the role of radical surgery in patients with this disease, who have a high likelihood of undergoing postoperative adjuvant therapy, we aimed to determine the rate of parametrial involvement and the rate of parametrial involvement without other indications for adjuvant treatment in these patients.

Methods: We retrospectively studied patients in the Neuroendocrine Cervical Tumor Registry (NeCTuR) at our institution to identify those with International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IA1-IB2, high-grade neuroendocrine cervical carcinoma who underwent up-front radical surgery with or without adjuvant therapy.

Introduction: The purpose of this study was to compare operative times, surgical outcomes, resource utilization, and hospital charges before and after the implementation of a sentinel lymph node (SLN) mapping algorithm in endometrial cancer.

Methods: All patients with clinical stage I endometrial cancer were identified pre- (2012) and post- (2017) implementation of the SLN algorithm. Clinical data were summarized and compared between groups.

Objective: To determine the feasibility of pharmacologic beta-adrenergic blockade in women with newly diagnosed stage II-IV epithelial ovarian cancer (EOC) throughout primary treatment.

Methods: Patients initiated propranolol prior to beginning chemotherapy or surgery. Feasibility was assessed as proportion able to complete 6 chemotherapy cycles while on adrenergic suppression.

Introduction: Cancer-related drowsiness (CRD) is a distressing symptom in advanced cancer patients (ACP). The aim of this study was to determine the frequency and factors associated with severity of CRD. We also evaluated the screening performance of Edmonton Symptom Assessment Scale-drowsiness (ESAS-D) item against the Epworth Sedation Scale (ESS).

Objective: Risk-reducing salpingo-oophorectomy (RRSO) reduces ovarian cancer risk in BRCA1/2 mutation carriers, but the adverse effects of the associated early-onset surgical menopause are problematic. Despite suggestive evidence, no data demonstrate whether bilateral salpingectomy alone lowers the risk of developing ovarian cancer in BRCA mutation carriers. We conducted a pilot study of bilateral salpingectomy with delayed oophorectomy (BS/DO) in BRCA mutation carriers to determine the safety and acceptability of the procedure.

Background: To identify clinically relevant genomic rearrangement signatures in high-grade serous ovarian cancer (HGSOC), we conducted a retrospective analysis of sequenced HGSOC whole-tumor genomes.

Methods: Clinical data and whole-genome sequencing (WGS) reads were obtained for primary HGSOC tumors sequenced by the Australian Ovarian Cancer Study (AOCS; n = 80). Genomic rearrangements were identified, and non-negative matrix factorization (NMF) was used to extract rearrangement signatures.

Objectives: This study aims to examine practice patterns of gynecologic oncologists (GO) regarding fertility-sparing treatments (FST) for gynecology malignancies and explores attitudes toward collaboration with reproductive endocrinologists (RE).

Methods: An anonymous 23-question survey was sent to 1087 GO with a 14.0% completion rate.

Purpose: Sepsis accounts for only 2% of the hospitalizations worldwide but more than 17% of total in-hospital mortality. Inappropriate antimicrobial selection and delays in appropriate therapy have been associated with reduced survival in severe sepsis and septic shock. No studies to date have exclusively targeted septic oncologic patients without hypotension.

Recent studies show that colorectal tumors with high microsatellite instability (MSI-H) have increased immunogenicity and response to immunotherapy compared with microsatellite-stable (MSS) tumors. It is not yet clear whether MSI-H endometrial cancer may also benefit from these therapies. It is also unknown whether immune response is equivalent in MSI-H endometrial cancer with sporadic or inherited Lynch syndrome origins.

Objective: The aim of this study was to determine the factors associated with a feeling of well-being using the Edmonton Symptom Assessment Scale (ESAS)-Feeling of Well-Being item (ESAS-FWB; where 0 = best and 10 = worst) among advanced lung or non-colonic gastrointestinal cancer patients who were referred to an outpatient palliative care clinic (OPCC). We also examined the association of performance on the ESAS-FWB with overall survival (OS).

Method: We reviewed the records of consecutive patients with incurable advanced lung cancer and non-colonic gastrointestinal cancer presenting to an OPCC from 1 January 2008 through to 31 December 2013.

Importance: Information regarding treatment options and prognosis is essential for patient decision making. Patient perception of physicians as being less compassionate when they deliver bad news might be a contributor to physicians' reluctance in delivering these types of communication.

Objective: To compare patients' perception of physician compassion after watching video vignettes of 2 physicians conveying a more optimistic vs a less optimistic message, determine patients' physician preference after watching both videos, and establish demographic and clinical predictors of compassion.
