RESUMEN

OBJECTIVE: To assess risk factors associated with loss to follow up in patients referred for colposcopy after abnormal cervical cytology during pregnancy in a Southern safety net hospital population. METHODS: An urban colposcopy center was queried for patients referred for follow up of abnormal cervical cytology during pregnancy and the postpartum period. Patients were identified through a standardized referral code in the electronic medical record. Multivariable logistic regression was used to compare patient characteristics between those who followed up for colposcopy and those lost to follow up. Independent risk factors assessed included age, parity, race, insurance, HIV status, history of mental illness, BMI, gestational age and trimester at screening, cytology at colposcopy referral, interval days until colposcopy, and biopsy histology. RESULTS: 1063 patients were identified, with 40.8% of patients who completed referred colposcopy. Patient characteristics predictive for colposcopy follow up included: maternal age at referral cervical cytology >30 years (1.67; 1.27-2.20; < 0.003), gestational age < 18 weeks at abnormal cervical cytology (1.57; 1.23-2.01; <0.0002), maternal race non-African American (2.20; 1.32-3.65; <0.0024) and with high grade cervical cytology (2.42; 1.81-3.24; <0.0001). CONCLUSION: In this population, inadequate follow up for abnormal cervical cytology during pregnancy is prominent, especially among those with younger maternal age, African American (AA) race, cervical cytology completed at later gestational ages of pregnancy, and low-grade initial cytology. Higher no-show rate among AA patients supports well-documented health disparities and need for further investigation and protocols to identify those at risk for loss to follow up.

RESUMEN

OBJECTIVES: To evaluate high-risk human papillomavirus testing (hrHPV) as an alternative for anal cytology in screening for high-grade anal neoplasia (AIN2-3) among males with HIV. To identify predictive risk factors for AIN2-3 and develop a clinical tool to triage males with HIV for high-resolution anoscopy (HRA) without cytology. DESIGN: Retrospective cohort study of 199 adult cisgender men and transgender women with HIV referred to an anal neoplasia clinic in the Southeastern United States between January 2018 and March 2021. METHODS: Each subject underwent cytology, hrHPV, and HRA. Clinical and sociodemographic risk factors were collected for each subject. Significant risk factors for AIN2-3 were identified using logistic regression, and a triage tool incorporating these factors was developed. Screening test characteristics were calculated for cytology with and without adjunct hrHPV, hrHPV alone, and the triage tool. RESULTS: In multivariate analysis, significant predictors of AIN2-3 were hrHPV positivity (odds ratio [OR] = 11.98, CI = 5.58-25.69) and low CD4 count (OR = 2.70, CI = 1.20-6.11). There was no significant difference in positive or negative predictive values among the tool, stand-alone hrHPV, and anal cytology with adjunct hrHPV. Sensitivity and specificity were not significantly different for stand-alone or adjunctive hrHPV testing. Compared with cytology, stand-alone hrHPV and the novel triage tool reduced unnecessary HRA referrals by 65% and 30%, respectively. CONCLUSIONS: Stand-alone hrHPV would have missed 11 of 74 AIN2-3 and generated 74 fewer unnecessary HRAs than current cytology-based screening patterns, which led to 115 unnecessary HRAs in our cohort. We propose triaging those with low CD4 count, hrHPV positivity, and/or smoking history for HRA.

RESUMEN

OBJECTIVES: Sexual gender minority (SGM) populations are at risk for human papillomavirus (HPV)-related cancers of the anogenital tract and oropharynx and often face barriers to health care. The goals of this document are to clarify language to provide inclusive care for SGM populations and to provide recommendations for screening and prevention of HPV-related cancers in SGM populations. MATERIALS AND METHODS: An expert committee convened by the American Society for Colposcopy and Cervical Pathology performed a narrative review of the literature through February 2023. A comprehensive MEDLINE database search was performed for relevant studies. The literature review was divided into categories by organ/topic and by SGM population. Given the variability in available data for several of the categories, recommendations were made based on national guidelines where appropriate or expert opinion where there were less data to support risk-based guidelines. RESULTS: Definitions and terminology relevant to SGM populations are presented. The authors advocate the adoption of sexual orientation gender identity data collection and an organ-based screening approach, which is possible with knowledge of patient anatomy, sexual behaviors, and clinical history. This includes screening for cervical cancer per national recommendations, as well as screening for anal, vulvar, vaginal, penile, and oral cancers based on risk factors and shared clinical decision making. The authors recommend consideration of HPV vaccination in all SGM individuals up to age 45 years old who are at risk. CONCLUSIONS: An organ-based screening approach is part of a global strategy to create an inclusive care environment and mitigate barriers to screening and prevention of HPV-mediated cancers in SGM populations.

RESUMEN

METHODS: The authors conducted a survey for practicing gynecologists recruited through academic institutions, professional societies, and professional groups on social media resulting in 196 respondents. The survey, fielded between January and June 2022, included questions on knowledge, attitudes, training, and practices regarding anal cancer prevention (ACP). Descriptive statistics and χ 2 analysis were completed. RESULTS: In terms of knowledge regarding ACP, over 80% of respondents identified certain clinical indications for anal cancer screening. However, only 36% respondents selected the 3 correct ACP screening tools. Twenty-seven (13.9%) respondents reported receiving training on ACP in medical school, whereas 50 (25.9%) reported receiving training during residency. Only 21% of respondents reported that they perform anal cytology, and 32% reported that they perform digital anal rectal examinations. One hundred thirty-six respondents (75.56%) affirmed that they needed additional training on ACP to be able to provide this service to their patients, and 95 (53.1%) stated they were extremely likely to participate in ACP training if given the opportunity. CONCLUSION: Although a limited proportion of practicing gynecologists are trained in ACP, there is willingness to participate in training if it were made available and to incorporate ACP into their practices.

RESUMEN

Cervical cancer is one of the most common gynecological malignancies. Upregulation of programmed death ligand-1 (PD-L1), an immunoregulatory protein, is associated with an adverse outcomes in several malignancies. Most studies evaluating PD-L1 expression in cervical squamous cell carcinoma (CSCC) lack data on outcomes. In this study, we correlate PD-L1 expression with clinicopathologic factors and clinical outcomes in invasive CSCC. Seventy-three cases of CSCC from 2010 to 2018 were immunostained for PD-L1. A combined positive score (CPS) of ≥1 and ≥10 was correlated with age, stage, and survival outcomes. Kaplan-Meier curves for progression-free survival and overall survival were plotted and compared using the log-rank test. Cox regression analysis was performed to identify significant prognostic factors (2-tailed P <0.05 was considered statistically significant). With CPS ≥1 or ≥10 as the cut-off, PD-L1 was positive in 52/73 (71.2%) and 23/73 (31.5%) of cases, respectively. PD-L1 positive patients present at a higher stage of disease, especially those with CPS ≥10. With CPS of ≥10 as the cut-off, the 5-yr progression-free survival and 5-yr overall survival were significantly lower ( P = 0.034 and 0.012, respectively). Only stage was statistically significant for worse overall survival on multivariate analysis. PD-L1 positive patients present at a higher stage of disease, and stage is an independent prognostic indicator for adverse outcomes in CSCC. This study highlights the potential of PD-L1 targeted therapy in patients with CSCC.

RESUMEN

Background: Menstrual equity, that is, access to menstrual products and safe menstruating environments, is a basic human right not available to many vulnerable populations. Methods: We conducted a cross-sectional survey with a convenience sample of women involved in the criminal legal system to document experiences with access to hygiene and menstrual products while incarcerated. Results: Of the 156 respondents, 62.6% had to trade or barter to receive even basic hygiene products such as soap or shampoo; food and personal favors were used as the common currency. More than half (53.8%) received less than five menstrual products at intake/initial processing; 29.5% had to trade or barter menstrual hygiene products. Almost one-quarter (23.1%) suffered negative health consequences from prolonged use of products because of limited supply. Discussion: Findings document the lack of menstrual equity among women involved in the criminal legal system. Assuring the human right of menstrual equity in this population requires changes at the legal, the policy, the institutional, and the individual level.

RESUMEN

OBJECTIVES: Individuals treated for cervical intraepithelial neoplasia grade 2 or worse (CIN2+) are at long-term risk of persistent or recurrent disease despite treatment. This committee opinion aims to summarize and provide evidence-based recommendations for adjuvant human papillomavirus (HPV) vaccination based on available, published literature. METHODS: A task force from the ASCCP Practice Committee reviewed current Centers for Disease Control and Prevention (CDC) guidelines and previously published literature about the role of adjuvant HPV vaccination in previously unvaccinated individuals undergoing treatment for CIN2+ and other HPV-related diseases. RESULTS: Current CDC guidelines recommend routine or catch-up HPV vaccination for individuals aged 9 to 26 years, and shared decision making regarding vaccination for individuals aged 27 to 45 years. Multiple published studies suggest a possible benefit for adjuvant HPV vaccination in previously unvaccinated individuals undergoing treatment for CIN2+. CONCLUSIONS: The American Society for Colposcopy and Cervical Pathology recommends adherence to current CDC recommendations for vaccination of individuals aged 9 to 26 years and consideration of the possible benefit of adjuvant HPV vaccination during shared decision making for previously unvaccinated individuals aged 27 to 45 years who are undergoing treatment for CIN2+.

RESUMEN

OBJECTIVE: This study aimed to evaluate factors associated with anal high-grade intraepithelial lesions (HSIL) and anal carcinoma among young men who have sex with men (MSM) and transgender women (TW) with HIV in Atlanta, GA, to better inform screening guidelines and preventative measures. MATERIALS AND METHODS: Cross-sectional retrospective chart review was completed for cisgender MSM and TW with HIV aged 13-25 years at the Grady Ponce and Family Youth Clinic in Atlanta, GA, from 2009 to 2020. High-grade anal disease was defined as anal intraepithelial neoplasia (AIN) 2, 3, or anal carcinoma (AIN 2+). Associations between clinical and demographic factors with AIN 2+ were estimated using logistic regression. Adjusted odds ratios (aORs) and associated 90% CIs are reported. RESULTS: One hundred nine MSM and TW with HIV who underwent anoscopy were included. One hundred three participants received anal biopsies, and 62% had AIN 2+. Being incompletely or unvaccinated against human papillomavirus (HPV, 0-2 doses) relative to being fully vaccinated (3 doses; aOR = 5.85; 90% CI = 1.28-26.83; p = .06) and having ever received surgical treatment for anogenital HPV (aOR = 2.89; 90% CI = 1.10-7.65; p = .07) were associated with AIN 2+, controlling for age and CD4 T-cell count at time of biopsy. CONCLUSIONS: Our study found a high prevalence of anal HSIL among young MSM and TW with HIV. Those who had ever received surgical treatment for anogenital HPV and those who were incompletely or unvaccinated against HPV were more likely to have HSIL. Our data emphasize the urgent need to improve HPV vaccination efforts and to pursue larger surveillance studies of anal HSIL and carcinoma among young MSM and TW with HIV.

RESUMEN

Current expert recommendations suggest anal cytology followed by high-resolution anoscopy (HRA) for biopsy and histological confirmation may be beneficial in cancer prevention, especially in people living with HIV (PLWH). Guided by the social ecological model, the purpose of this study was to examine sociodemographic and clinical variables, individual-level factors (depression, HIV/AIDS-related stigma, and health beliefs) and interpersonal-level factors (social support) related to time to HRA follow-up after abnormal anal cytology. We enrolled 150 PLWH from a large HIV community clinic, with on-site HRA availability, in Atlanta, GA. The median age was 46 years (interquartile range of 37-52), 78.5% identified as African American/Black, and 88.6% identified as born male. The average length of follow-up to HRA after abnormal anal cytology was 380.6 days (standard deviation = 317.23). Only 24.3% (n = 39) of the sample had an HRA within 6 months after an abnormal anal cytology, whereas 57% of the sample had an HRA within 12 months. HIV/AIDS-related stigma [odds ratio (OR) 0.54, 95% confidence interval (CI) 0.33-0.90] and health motivation (OR 0.80, 95% CI 0.67-0.95) were associated with time to HRA follow-up ≤6 months. For HRA follow-up ≤12 months, we found anal cytology [high-grade squamous intraepithelial lesions/atypical squamous cells of undetermined significance cannot exclude HSIL (HSIL/ASCUS-H) vs. low-grade squamous intraepithelial lesions (LSIL) OR = 0.05, 95% CI 0.00-0.70; atypical squamous cells of undetermined significance (ASCUS) vs. LSIL OR = 0.12, 95% CI 0.02-0.64] and health motivation (OR = 0.86, 95% CI 0.65-0.99) were associated. Findings from this study can inform strategies to improve follow-up care after abnormal anal cytology at an individual and interpersonal level in efforts to decrease anal cancer morbidity and mortality.

RESUMEN

BACKGROUND: The incidence of anal cancer is substantially higher among persons living with the human immunodeficiency virus (HIV) than in the general population. Similar to cervical cancer, anal cancer is preceded by high-grade squamous intraepithelial lesions (HSILs). Treatment for cervical HSIL reduces progression to cervical cancer; however, data from prospective studies of treatment for anal HSIL to prevent anal cancer are lacking. METHODS: We conducted a phase 3 trial at 25 U.S. sites. Persons living with HIV who were 35 years of age or older and who had biopsy-proven anal HSIL were randomly assigned, in a 1:1 ratio, to receive either HSIL treatment or active monitoring without treatment. Treatment included office-based ablative procedures, ablation or excision under anesthesia, or the administration of topical fluorouracil or imiquimod. The primary outcome was progression to anal cancer in a time-to-event analysis. Participants in the treatment group were treated until HSIL was completely resolved. All the participants underwent high-resolution anoscopy at least every 6 months; biopsy was also performed for suspected ongoing HSIL in the treatment group, annually in the active-monitoring group, or any time there was concern for cancer. RESULTS: Of 4459 participants who underwent randomization, 4446 (99.7%) were included in the analysis of the time to progression to cancer. With a median follow-up of 25.8 months, 9 cases were diagnosed in the treatment group (173 per 100,000 person-years; 95% confidence interval [CI], 90 to 332) and 21 cases in the active-monitoring group (402 per 100,000 person-years; 95% CI, 262 to 616). The rate of progression to anal cancer was lower in the treatment group than in the active-monitoring group by 57% (95% CI, 6 to 80; P = 0.03 by log-rank test). CONCLUSIONS: Among participants with biopsy-proven anal HSIL, the risk of anal cancer was significantly lower with treatment for anal HSIL than with active monitoring.

RESUMEN

STUDY OBJECTIVE: To identify the incidence, type, and grade of postoperative adverse events in minimally invasive radical hysterectomy vs abdominal radical hysterectomy (ARH) for patients with early-stage cervical cancer and determine risk factors associated with these adverse events. DESIGN: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) was queried to identify patients with early-stage cervical cancer undergoing radical hysterectomy. Multivariable logistic regression was used to assess risk factors associated with adverse postoperative outcomes among patients undergoing radical hysterectomy. SETTING: ACS NSQIP participating institutions within the United States. PATIENTS: Patients were collected from the ACS NSQIP databases (2014-2017) undergoing radical hysterectomy for early-stage cervical cancer. INTERVENTIONS: N/A MEASUREMENTS AND MAIN RESULTS: ARH had a significantly increased incidence of any 30-day postoperative adverse event compared with minimally invasive radical hysterectomy (31.2% vs 19.9%, p <.001). There was a higher incidence of surgical site infection, both deep and superficial, and blood transfusions in ARH. On multivariable logistic regression, the abdominal surgical approach was the only risk factor significantly associated with any postoperative adverse event (odds ratio, 1.4; confidence interval, 1.1-1.9; p = .018; 95% CIs). CONCLUSIONS: In this study, the abdominal surgical approach for radical hysterectomy in early-stage cervical cancer was associated with a higher incidence of postoperative adverse events than the minimally invasive approach.

RESUMEN

OBJECTIVES: Women living with HIV (WLWH) have a greater risk of anal cancer than women without HIV; however, there are limited studies that examine awareness of anal cancer risk among WLWH and "high-risk" HIV-negative women. This study examines risk factors for anal cancer, perceptions of risk for anal cancer, and perceptions of anal cancer screening among a cohort of WLWH and high-risk HIV-negative women. MATERIALS AND METHODS: From the Atlanta, GA, and Bronx, NY, sites of the Women's Interagency HIV Study, 155 WLWH and HIV-negative women were enrolled and the Champion Health Belief Model Scale questionnaire measuring risk perceptions to anal cancer was administered to each participant. RESULTS: The WLWH perceived anal cancer to be less serious and perceived facing fewer barriers to anal cancer screening than HIV-negative women (both p = .01). Older women (≥50 years) felt that they had less barriers to anal cancer screening (p = .047). Moreover, women who had less than a high school education felt more susceptible to anal cancer (p = .001), as did women who reported a history of anal intercourse (p = .017). CONCLUSIONS: Despite being at an increased risk for anal cancer, perceptions of susceptibility to anal cancer and seriousness of anal cancer were low among WLWH. These findings highlight opportunities for provider and patient educational interventions to improve awareness of anal cancer risk among WLWH.

RESUMEN

CONTEXT.­: Upregulation of programmed death ligand-1 (PD-L1), an immunoregulatory protein, is associated with an adverse outcome in several malignancies. Very few studies have evaluated PD-L1 expression in invasive anal squamous cell carcinoma (ASCC). OBJECTIVE.­: To assess PD-L1 expression in patients with ASCC and correlate it with clinicopathologic factors and clinical outcomes. DESIGN.­: Fifty-one cases of ASCC were immunostained for PD-L1. PD-L1 expression by combined positive score and tumor proportion score was correlated with age, sex, HIV status, HIV viral load, CD4 count, stage, and outcomes. Kaplan-Meier curves for overall survival were plotted and compared using the log-rank test. Cox regression analysis was performed to identify significant prognostic factors (2-tailed P < .05 was considered statistically significant). RESULTS.­: PD-L1 was positive in 24 of 51 cases (47%) by combined positive score and in 18 of 51 (35%) by tumor proportion score. The median cancer-specific survival and 5-year overall survival were significantly lower in PD-L1+ patients. Age, sex, HIV status, HIV viral load, stage, and cancer progression were not significantly different between the 2 groups. CD4 count of more than 200/µL was significantly higher in PD-L1+ patients. PD-L1+ status remained statistically significant for worse overall survival on multivariate analysis. CONCLUSIONS.­: PD-L1+ status is an independent adverse prognostic factor for overall survival in ASCC. This study highlights the potential of PD-L1 targeted therapy in better management of ASCC.

RESUMEN

Since the first case of COVID-19 was identified in the USA in January, 2020, over 46 million people in the country have tested positive for SARS-CoV-2 infection. Several COVID-19 vaccines have received emergency use authorisations from the US Food and Drug Administration, with the Pfizer-BioNTech vaccine receiving full approval on Aug 23, 2021. When paired with masking, physical distancing, and ventilation, COVID-19 vaccines are the best intervention to sustainably control the pandemic. However, surveys have consistently found that a sizeable minority of US residents do not plan to get a COVID-19 vaccine. The most severe consequence of an inadequate uptake of COVID-19 vaccines has been sustained community transmission (including of the delta [B.1.617.2] variant, a surge of which began in July, 2021). Exacerbating the direct impact of the virus, a low uptake of COVID-19 vaccines will prolong the social and economic repercussions of the pandemic on families and communities, especially low-income and minority ethnic groups, into 2022, or even longer. The scale and challenges of the COVID-19 vaccination campaign are unprecedented. Therefore, through a series of recommendations, we present a coordinated, evidence-based education, communication, and behavioural intervention strategy that is likely to improve the success of COVID-19 vaccine programmes across the USA.

RESUMEN

ABSTRACT: The American Cancer Society (ACS) released updated cervical cancer screening guidelines in 2020 that endorse a shift in practice to primary human papillomavirus (HPV) screening in people with a cervix, beginning at ages of 25-65 years. When access to US Food and Drug Administration-approved primary HPV testing is not available, the ACS offers cotesting or cytology as acceptable alternative strategies but suggests that these testing modalities may be excluded from future iterations of the guidelines. The ASCCP recognizes the benefits and risks of primary HPV cervical cancer screening while acknowledging the barriers to widespread adoption, including implementation issues, the impact of limited HPV vaccination in the United States, and inclusion of populations who may not be well represented on primary HPV screening trials, such as underrepresented minorities. The ASCCP endorses the 2018 US Preventive Services Task Force Recommendation Statement and supports the ACS cervical cancer screening guidelines. Most importantly, the ASCCP endorses any cervical cancer screening for secondary prevention of cervical cancer and recommends interventions that improve screening for those who are underscreened or unscreened.
