Efficacy of Cobas HPV testing for predicting grade 2+ cervical intraepithelial neoplasia in a cancer prevention center and a gynecologic oncology clinic: A single-institution experience.

Background: To evaluate the efficacy of Cobas human papillomavirus (HPV) testing to predict cervical intraepithelial neoplasia of grade 2 or higher (CIN2+), Cobas HPV testing results were correlated with follow-up biopsy in patients from Cancer Prevention Center (CPC) and Gynecologic Oncology Clinic (GOC) of The University of Texas MD Anderson Cancer Center.

Methods: Institutional data for patients who underwent Cobas HPV and Papanicolaou (Pap) cytology cotesting from 2019 to 2020 were retrospectively reviewed. Surgical follow-up results were compared with Cobas HPV testing results in two populations.

Scanning darkfield high-resolution microendoscope for label-free microvascular imaging.

Characterization of microvascular changes during neoplastic progression has the potential to assist in discriminating precancer and early cancer from benign lesions. Here, we introduce a novel high-resolution microendoscope that leverages scanning darkfield reflectance imaging to characterize angiogenesis without exogenous contrast agents. Scanning darkfield imaging is achieved by coupling programmable illumination with a complementary metal-oxide semiconductor (CMOS) camera rolling shutter, eliminating the need for complex optomechanical components and making the system portable, low-cost (<$5,500) and simple to use.

HPV-related anal cancer is associated with changes in the anorectal microbiome during cancer development.

Background: Squamous cell carcinoma of the anus (SCCA) is a rare gastrointestinal cancer. Factors associated with progression of HPV infection to anal dysplasia and cancer are unclear and screening guidelines and approaches for anal dysplasia are less clear than for cervical dysplasia. One potential contributing factor is the anorectal microbiome.

Malignancy in pregnancy: Multimodality imaging and treatment.

The diagnosis of cancer is increasingly made in the pregnant population, thought to be from the increasing average age of pregnancy and the use of prenatal fetal noninvasive screening techniques, leading to incidental detection of cancer in the mother. Complex challenges are associated with imaging, diagnosis, staging, and treatment of cancers in this patient population, which require highly specialized interdisciplinary management. This report discusses the use of multimodality imaging and safety considerations in pregnant patients, reviews the current guidelines for ionizing radiation imaging techniques, and presents a series of commonly and uncommonly encountered cancers in pregnancy with current diagnostic imaging guidelines.

A Cross-Sectional Study of the Prevalence of Anal Dysplasia among Women with High-Grade Cervical, Vaginal, and Vulvar Dysplasia or Cancer: The PANDA Study.

Background: High-risk human papillomavirus (HR-HPV) infection is a risk factor for anal cancer, yet no anal cancer screening guidelines exist for women with lower genital tract HPV-related disease. We sought to describe the prevalence of anal HR-HPV or cytologic abnormalities in such women.

Methods: This cross-sectional study was performed between October 2018 and December 2021.

Condyloma and coincidental epidermodysplasia verruciformis acanthoma positive for human papillomavirus-14 and -21.

Epidermodysplasia verruciformis (EDV) is a rare genodermatosis that predisposes individuals to persistent infection with β-human papillomavirus (HPV) genotypes. The term EDV acanthoma may be applied to lesions with incidental findings of EDV-defining histopathological features without clinical signs of EDV. We report a case of HPV-14- and -21-positive EDV acanthoma arising in association with condyloma in a female patient with a history of low-grade squamous intraepithelial lesion of the cervix positive for high-risk HPV (non-16/18), chronic kidney disease, and systemic lupus erythematosus.

Addressing high cervical cancer rates in the Rio Grande Valley along the Texas-Mexico border: a community-based initiative focused on education, patient navigation, and medical provider training/telementoring.

Aims: Cervical cancer incidence and mortality rates are approximately 55% higher in the Rio Grande Valley (RGV) along the Texas-Mexico border compared with the average rates in the US. Our aim was to improve cervical cancer prevention efforts in the RGV through a comprehensive multilevel intervention initiative focused on community education, patient navigation, and training of local providers.

Methods: We initiated a program in the RGV which consisted of (1) community education, (2) patient navigation, and (3) a training/mentoring program for local medical providers including hands-on training courses coupled with telementoring using (Extension for Community Health Outcomes).

Prospective phase II trial of levonorgestrel intrauterine device: nonsurgical approach for complex atypical hyperplasia and early-stage endometrial cancer.

Background: The incidence of complex atypical hyperplasia and early-stage endometrioid endometrial cancer is increasing, in part owing to the epidemic of obesity, which is a risk factor tightly linked to the development of endometrial hyperplasia and cancer. The standard upfront treatment for complex atypical hyperplasia and early-stage endometrial cancer is hysterectomy. However, nonsurgical treatment of early-stage endometrial neoplasia may be necessary owing to medical comorbidities precluding surgery or desired future fertility.

In vivo imaging of cervical precancer using a low-cost and easy-to-use confocal microendoscope.

Cervical cancer incidence and mortality rates remain high in medically underserved areas. In this study, we present a low-cost (<$5,000), portable and user-friendly confocal microendoscope, and we report on its clinical use to image precancerous lesions in the cervix. The confocal microendoscope employs digital apertures on a digital light projector and a CMOS sensor to implement line-scanning confocal imaging.

Toward development of a large field-of-view cancer screening patch (CASP) to detect cervical intraepithelial neoplasia.

Cervical cancers are primarily diagnosed via colposcopy, in which the tissue is visually assessed by a clinician for abnormalities, followed by directed biopsies and histologic analysis of excised tissue. Optical biopsy technologies offer a less invasive method of imaging such that subcellular features can be resolved without removing tissue. These techniques, however, are limited in field-of-view by the distal end of the probe.

Low-cost, high-resolution imaging for detecting cervical precancer in medically-underserved areas of Texas.

Objective: Cervical cancer rates in the United States have declined since the 1940's, however, cervical cancer incidence remains elevated in medically-underserved areas, especially in the Rio Grande Valley (RGV) along the Texas-Mexico border. High-resolution microendoscopy (HRME) is a low-cost, in vivo imaging technique that can identify high-grade precancerous cervical lesions (CIN2+) at the point-of-care. The goal of this study was to evaluate the performance of HRME in medically-underserved areas in Texas, comparing results to a tertiary academic medical center.

Prevalence of high-grade anal dysplasia among women with high-grade lower genital tract dysplasia or cancer: Results of a pilot study.

Objective: To estimate the prevalence of high-grade anal dysplasia in women with high-grade dysplasia or carcinoma of the cervix, vagina or vulva.

Methods: In this cross-sectional study, participants underwent anal cytology, anal HPV testing with Cervista HPV16/18 and high-resolution anoscopy (HRA). Patients with HSIL (high-grade squamous cell intraepithelial lesion) or greater on anal cytology or anal biopsy were referred to a colorectal surgery specialist for further evaluation.

Perspectives on cervical cancer screening and prevention: challenges faced by providers and patients along the Texas-Mexico border.

Background: The Rio Grande Valley (RGV) and Laredo regions located along the Texas-Mexico border consist of seven counties with a population of approximately 1.5 million people and a high uninsured rate (33.5%).

Prospective Randomized Biomarker Study of Metformin and Lifestyle Intervention for Prevention in Obese Women at Increased Risk for Endometrial Cancer.

Obesity increases risk of endometrial cancer through dysregulation of estrogen and insulin signaling. The primary aim of this study was to evaluate the impact of metformin or lifestyle intervention on endometrial proliferation in postmenopausal obese women. Secondary aims included evaluating obesity-related biomarkers and adverse events experienced.

Gynecologic cancer survivor preferences for long-term surveillance.

Background: With ongoing healthcare reform and shrinking numbers of oncologists, appropriate triaging of gynecologic cancer survivor care is crucial. Input from patients is a necessary part of this task. The objective of this study was to assess the preferences of gynecologic cancer survivors for surveillance after the completion of treatment.

Treatment of Low-Risk Endometrial Cancer and Complex Atypical Hyperplasia With the Levonorgestrel-Releasing Intrauterine Device.

Objective: To assess efficacy of the levonorgestrel-releasing intrauterine device (LNG-IUD) for treatment of complex atypical hyperplasia or low-grade endometrial cancer.

Methods: This retrospective case series included all patients treated with the LNG-IUD for complex atypical hyperplasia or early-grade endometrial cancer from January 2003 to June 2013. Response rates were calculated and the association of response with clinicopathologic factors, including age, body mass index, and uterine size, was determined.

Project ECHO: A Telementoring Program for Cervical Cancer Prevention and Treatment in Low-Resource Settings.

Cervical cancer incidence and mortality rates are significantly higher in low- and middle-income countries compared with the United States and other developed countries. This disparity is caused by decreased access to screening, often coupled with low numbers of trained providers offering cancer prevention and treatment services. However, similar disparities are also found in underserved areas of the United States, such as the Texas-Mexico border, where cervical cancer mortality rates are 30% higher than in the rest of Texas.

Maternal and Fetal Outcomes After Therapy for Hodgkin or Non-Hodgkin Lymphoma Diagnosed During Pregnancy.

Importance: The management of lymphoma diagnosed during pregnancy is controversial and has been guided largely by findings from case reports and small series.

Objective: To determine maternal and fetal outcomes of women diagnosed with Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL) during pregnancy.

Design, Setting, And Participants: This retrospective analysis studied a cohort of 39 pregnant women diagnosed with HL and NHL (31 HL and 8 NHL) at a single specialized cancer institution between January 1991 and December 2014.

Avoidable tragedies: Disparities in healthcare access among medically underserved women diagnosed with cervical cancer.

Background: The purpose was to identify barriers including logistical and health belief correlates of late stage presentation of cervical cancer (CxCa) among medically underserved women presenting to a safety net health care system.

Methods: Women presenting with newly diagnosed CxCa were asked to complete a detailed health belief survey that included questions about barriers to care and their knowledge of CxCa. All information was collected prior to initiating cancer treatment.

High-Grade Cervical Dysplasia following Radiation Therapy for Invasive Cervical Cancer: A Report of Four Cases.

Introduction: The standard treatment for locally advanced cervical cancer is chemoradiation, with the majority of patients having a complete response to the therapy. The current surveillance recommendations from the Society of Gynecologic Oncology include annual cytology, with a small proportion of patients subsequently diagnosed with high-grade cervical dysplasia (CIN 2/3). To date, there is limited information regarding the optimal treatment and outcome for patients diagnosed with CIN 2/3.

Outcomes of children exposed in utero to chemotherapy for breast cancer.

Introduction: The incidence of breast cancer diagnosed during pregnancy is expected to increase as more women delay childbearing in the United States. Treatment of cancer in pregnant women requires prudent judgment to balance the benefit to the cancer patient and the risks to the fetus. Prospective data on the outcomes of children exposed to chemotherapy in utero are limited for the breast cancer population.

Pregnancy and glial brain tumors.

Background: Improvements in brain tumor treatments have led to an increase in the number of young women with brain tumors who are now considering pregnancy. The aim of this study is to evaluate the influence of pregnancy on brain tumor biology.

Methods: In this institutional review board-approved retrospective study, we searched the institution's database for patients with glial brain tumors who were pregnant at the time of diagnosis or became pregnant during the course of their illness.

Prospective multicenter randomized intermediate biomarker study of oral contraceptive versus depo-provera for prevention of endometrial cancer in women with Lynch syndrome.

Women with Lynch syndrome have a 40% to 60% lifetime risk for developing endometrial cancer, a cancer associated with estrogen imbalance. The molecular basis for endometrial-specific tumorigenesis is unclear. Progestins inhibit estrogen-driven proliferation, and epidemiologic studies have shown that progestin-containing oral contraceptives (OCP) reduce the risk of endometrial cancer by 50% in women at general population risk.
