Objective: Patients with intermediate-risk cervical cancer receive external beam radiotherapy (EBRT) as adjuvant treatment. It is commonly administered with brachytherapy without proven benefits. Therefore, we evaluated the frequency of brachytherapy use, the doses for EBRT administered alone or with brachytherapy, and the overall survival impact of brachytherapy in patients with intermediate-risk, early-stage cervical cancer.

Article Synopsis
  • The study investigates how geographic factors influence the use of fertility-sparing treatments and assisted reproductive technology (ART) in women diagnosed with gynecologic or breast cancers between 2000 and 2015.
  • Utilizing data from California health registries, researchers analyzed the impact of distance from fertility and oncology clinics and community health scores on treatment uptake among reproductive-aged patients.
  • Results show that women living farther from these clinics were less likely to receive fertility-sparing treatments and that those in healthier communities (higher California Healthy Places Index scores) had better odds of undergoing such treatments.

The traditional histological classification system for endometrial carcinoma falls short in addressing the disease's molecular heterogeneity, prompting the need for alternative stratification methods. Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE) has emerged as a clinically efficient tool to categorize endometrial cancers according to mismatch repair deficiency, POLE exonuclease domain mutations, and p53 expression. However, the application of this classification to fertility-sparing treatments remains unexplored, and current guidelines lack specificity in how it should be used.

Unlabelled: We sought to explore the intrafamilial communication and cascade genetic testing (CGT) experiences of patients with hereditary cancer from diverse, medically underserved populations and their relatives. Participants included patients receiving oncology care at an urban, safety net hospital in Texas or comprehensive cancer center in Alabama and their first-degree relatives. In-depth semi-structured qualitative interviews were completed wherein patients shared their experiences with genetic counseling (GC), genetic testing (GT), and communicating their results to relatives.

Objective: The etiology of inferior oncologic outcomes associated with minimally invasive surgery for early-stage cervical cancer remains unknown. Manipulation of lymph nodes with previously unrecognized low-volume disease might explain this finding. We re-analyzed lymph nodes by pathologic ultrastaging in node-negative patients who recurred in the LACC (Laparoscopic Approach to Cervical Cancer) trial.

Financial toxicity describes the adverse impact patients experience from the monetary and time costs of cancer care. The financial burden patients experience comes from substantially increased out-of-pocket spending that often occurs concurrent with reduced income due to sick leave from work. Financial toxicity is common affecting approximately half of patients with a gynecological cancer depending on the validated instrument used for measurement.

Objective: To assess the presence of sociodemographic and clinical disparities in fertility-sparing treatment and assisted reproductive technology (ART) use among patients with a history of cervical, endometrial, or ovarian cancer.

Methods: We conducted a population-based cohort study of patients aged 18-45 years who were diagnosed with cervical cancer (stage IA, IB), endometrial cancer (grade 1, stage IA, IB), or ovarian cancer (stage IA, IC) between January 1, 2000, and December 31, 2015, using linked data from the CCR (California Cancer Registry), the California Office of Statewide Health Planning and Development, and the Society for Assisted Reproductive Technology. The primary outcome was receipt of fertility-sparing treatment , defined as surgical or medical treatment to preserve the uterus and at least one ovary.

Objective: To evaluate obstetric and neonatal outcomes of the first live birth conceived 1 or more years after breast cancer diagnosis.

Methods: We performed a population-based study to compare live births between women with a history of breast cancer (case group) and matched women with no cancer history (control group). Individuals in the case and control groups were identified using linked data from the California Cancer Registry and California Office of Statewide Health Planning and Development data sets.

Article Synopsis
  • Cascade genetic testing for hereditary cancer syndromes helps at-risk relatives access cancer screenings and preventive surgeries, reducing health risks while improving overall quality of life.
  • In a pilot study involving 95 participants, two years later, 76% followed up, and 44% of those found a genetic mutation were able to pursue recommended cancer screenings and surgeries.
  • Results displayed low anxiety and depression levels among participants, indicating that clinician-facilitated cascade testing is beneficial and should be further explored in larger studies.

Cascade testing for familial cancer syndromes has historically been difficult to execute. As part of a facilitated cascade testing pathway, we evaluated barriers to completion of cascade testing. Our previously published study evaluated a facilitated cascade testing pathway whereby a genetics team facilitated at-risk relative (ARR) cascade testing through telephone genetic counseling and mailed saliva kit testing.

Purpose: Evidence-based guidelines recommend cascade genetic counseling and testing for hereditary cancer syndromes, providing relatives the opportunity for early detection and prevention of cancer. The current standard is for patients to contact and encourage relatives (patient-mediated contact) to undergo counseling and testing. Direct relative contact by the medical team or testing laboratory has shown promise but is complicated by privacy laws and lack of infrastructure.

Background: In recent years, there has been growing recognition of the financial burden of severe illness, including associations with higher rates of nonemployment, uninsurance, and catastrophic out-of-pocket health spending. Patients with gynecologic cancer often require expensive and prolonged treatments, potentially disrupting employment and insurance coverage access, and putting patients and their families at risk for catastrophic health expenditures.

Objective: This study aimed to describe the prevalence of insurance churn, nonemployment, and catastrophic health expenditures among nonelderly patients with gynecologic cancer in the United States, to compare within subgroups and to other populations and assess for changes associated with the Affordable Care Act.
