RESUMEN

Introduction: Young sexual minority men (SMM) bear the greatest burden of anal human papillomavirus (HPV) infections. We assessed anal HPV genotype discordance between the Linear Array (LA) and SPF10 PCR-DEIA-LiPA25 (LiPA25). Methods: Discordance was assessed between LA and LiPA25 using self-collected anal swabs from 120 SMM aged 18-29 who were recruited in 2014-2016. Multiple-type infection was explored as a potential confounder of testing agreement, along with clinical and behavioral factors such as HIV status, syphilis status, incarceration history, health insurance coverage, having 3 or more sex partners in the past 6 months, and co-infection with HPV-16. Results: Significant discordance was found for HPV-6, -11, -16, -31, -42, -54, and -59. Exploratory analyses suggest higher prevalence of genotype discordance in those living with HIV, those with 3 or more sex partners, and those who were positive for 4 or more HPV types. Conclusions: Our results highlight the importance of HPV detection methods which may inform different interpretations of research assessing anal HPV natural history among SMM at highest risk for HPV.

RESUMEN

Women living with HIV and breast cancer have poorer survival than HIV-negative women. Efavirenz-estrogen interactions are documented; however, the survival impact is unknown. Survival between women with estrogen-receptor positive breast cancer taking efavirenz (n = 38) and nonefavirenz regimens (n = 51) were compared. The 5-year overall-survival was 48.9% [95% confidence interval (CI) 33.0-72.2 and 51.1% (95% CI 34.0-76.8)] in the efavirenz and nonefavirenz groups, respectively suggesting efavirenz is unlikely driving poorer survival in women living with HIV and estrogen-receptor positive breast cancer.

RESUMEN

BACKGROUND: Despite a higher risk of classical Hodgkin lymphoma (cHL) in people with HIV and the demonstrated safety and efficacy of PD-1 blockade in cHL, there are limited data on the use of these agents in HIV-associated cHL (HIV-cHL). PATIENTS/METHODS: We retrospectively identified patients with HIV-cHL from the "Cancer Therapy using Checkpoint inhibitors in People with HIV-International (CATCH-IT)" database who received nivolumab or pembrolizumab, alone or in combination with other agents, and reviewed records for demographics, disease characteristics, immune-mediated adverse events (imAEs), and treatment outcomes. Changes in CD4+ T-cell counts with treatment were measured via Wilcoxon signed-rank tests. Overall response rate (ORR) was defined as the proportion of patients with partial or complete response (PR/CR) per 2014 Lugano classification. RESULTS: We identified 23 patients with HIV-cHL who received a median of 6 cycles of PD-1 blockade: 1 as 1st-line, 6 as 2nd-line, and 16 as ≥3rd-line therapy. Seventeen (74%) patients received monotherapy, 5 (22%) received nivolumab plus brentuximab vedotin, and 1 received nivolumab plus ifosfamide, carboplatin, and etoposide. The median baseline CD4+ T-cell count was 155 cells/µL, which increased to 310 cells/µL at end-of-treatment (P = .009). Three patients had grade 3 imAEs; none required treatment discontinuation. The ORR was 83% with median duration of response of 19.7 months. The median progression-free survival was 21.2 months and did not differ between patients with <200 versus ≥200 CD4+ cells/µL (P = .95). CONCLUSION: Our findings support the use of PD-1 blockade in HIV-cHL for the same indications as the general population with cHL.

RESUMEN

OBJECTIVES: People with HIV (PWH) may have an increased burden of penile cancer. We aimed to evaluate the risk of penile cancer in PWH compared with that of the general population. DESIGN: We conducted a nationwide retrospective matched cohort study of penile cancer incidence among veterans with HIV (VWH) compared with veterans without HIV. METHODS: We compared penile cancer incidence rates in 44 173 VWH to those of veterans without HIV ( N  = 159 443; 4 : 1 matched in age). We used Cox regression models to estimate hazard ratios and 95% confidence intervals (CIs) for associations with HIV infection and for penile cancer risk factors. RESULTS: HIV positivity was associated with an increased risk of penile cancer, with adjusted hazard ratios of 2.63 (95% CI 1.64-4.23) when adjusting for age, race/ethnicity, baseline BMI, smoking and alcohol use, economic means test, and history of condyloma. The risk increased to hazard ratio = 4.25 (95% CI 2.75-6.57) when adjusting for all factors except history of condyloma. Risk factors for penile cancer in VWH included lower nadir CD4 + count, less than 50% of follow-up time with undetectable HIV viral load, and history of condyloma. CONCLUSION: VWH - particularly those with low CD4 + counts, detectable HIV viral loads, or history of condyloma - are at increased risk of penile cancer, suggesting the penile cancer prevention activities are needed in this population.

RESUMEN

Importance: Federally qualified health centers (FQHCs) deliver health care to nearly 30 million underserved persons across the US, yet nationwide and state-level breast, cervical, and colorectal cancer screening use in FQHCs is not described. Furthermore, it is unknown how the underscreened FQHC population contributes to the total underscreened population at national and state levels. Objective: To describe national- and state-level breast, cervical, and colorectal cancer screening use among individuals served by FQHCs in the US and to estimate the percentage of underscreened individuals in the general population served by FQHCs. Design, Setting, and Participants: This cross-sectional analysis of cancer screening used data from January 1 through December 31, 2020, from the FQHC Uniform Data System, reported by 1364 FQHCs across the US, and self-reported estimates from the Behavioral Risk Factor Surveillance System. Participants were 16 696 692 US adults served by FQHCs who were eligible for breast (age, 50-74 years), cervical (age, 21-64 years), and colorectal (age, 50-75 years) cancer screening. Analyses were conducted between January 1 and June 30, 2023. Exposures: Breast, cervical, and colorectal cancer screening. Main Outcomes and Measures: Percentages of breast, cervical, and colorectal cancer screening-eligible individuals up to date on screening. Results: A total of 3 162 882 breast, 7 444 465 cervical, and 6 089 345 colorectal screening-eligible individuals were served by FQHCs in 2020. Nationally, screening use in FQHCs was 45.4% (95% CI, 45.4%-45.5%) for breast cancer, 51.0% (95% CI, 51.0%-51.1%) for cervical cancer, and 40.2% (95% CI, 40.1%-40.2%) for colorectal cancer. Screening use among the US general population was 78.2% (95% CI, 77.6%-78.9%) for breast cancer, 82.9% (95% CI, 82.3%-83.4%) for cervical cancer, and 72.3% (95% CI, 71.7%-72.8%) for colorectal cancer. The contribution of the underscreened population served by FQHCs to the national underscreened general population was 16.9% (95% uncertainty interval [UI], 16.4%-17.4%) for breast cancer, 29.7% (95% UI, 28.8%-30.7%) for cervical cancer, and 14.7% (95% UI, 14.4%-15.0%) for colorectal cancer. Conclusions and Relevance: Findings from this national cross-sectional study indicated major gaps in cancer screening use in FQHCs in the US. Improved prevention is urgently needed to address screening disparities.

RESUMEN

Background Anal cancer disproportionately affects sexual and gender minority individuals living with HIV. High-resolution anoscopy (HRA) is an in-clinic procedure to detect precancerous anal lesions and cancer, yet prospective data on factors associated with HRA attendance are lacking. We examined whether anal HPV sampling at home versus in a clinic impacts HRA uptake and assessed HRA acceptability. Methods Sexual and gender minority individuals were randomised to home-based self-sampling or clinical sampling. All were asked to attend in-clinic HRA 1year later. We regressed HRA attendance on study arm using multivariable Poisson regression and assessed HRA acceptability using χ 2 tests. Results A total of 62.8% of 196 participants who engaged in screening attended HRA. Although not significant (P =0.13), a higher proportion of participants who engaged in clinic-based screening attended HRA (68.5%) compared to home-based participants (57.9%). Overall, HRA uptake was higher among participants with anal cytology history (aRR 1.40, 95% CI 1.07-1.82), and lower among participants preferring a versatile anal sex position versus insertive (aRR 0.70, 95% CI 0.53-0.91), but did not differ by race or HIV serostatus. In the clinic arm, persons living with HIV had lower HRA attendance (42.9%) versus HIV-negative participants (73.3%) (P =0.02) and Black non-Hispanic participants had lower HRA attendance (41.7%) than White non-Hispanic participants (73.1%), (P =0.04). No differences in attendance by race or HIV status were observed in the home arm. Conclusions HRA uptake differed significantly by race and HIV status in the clinic arm but not the home arm.

RESUMEN

Background: Squamous cell carcinoma of the anus (SCCA) annual incidence among sexual minority men with and without HIV is 85/100,000 and 19/100,000 persons, respectively, which is significantly higher than the overall incidence (2/100,000). Incidence may also be higher in transgender women. Since SCCA tumours average ≥30 mm at diagnosis, we assessed the accuracy of individuals to self-detect smaller anal abnormalities. Methods: Using convenience sampling, the study enrolled sexual minority men and transgender women, aged 25-81 years, in Chicago, Illinois and Houston, Texas, USA, during 2020-2022. Individuals were taught the anal self-examination and anal companion examination (ASE/ACE). Then, a clinician performed a digital anal rectal examination (DARE) before participants conducted the ASE or ACE. The sensitivity, specificity and concordance of the ASE/ACE to detect an abnormality were measured along with factors associated with ASE/ACE and DARE concordance. Findings: Among 714 enrolled individuals, the median age was 40 years (interquartile range, 32-54), 36.8% (259/703) were living with HIV, and 47.0% (334/710), 23.4% (166/710), and 23.0% (163/710) were non-Hispanic white, non-Hispanic Black, and Hispanic, respectively. A total of 94.1% (671/713) identified as cisgendered men, and 5.9% (42/713) as gender minorities. A total of 658 participants completed an ASE and 28 couples (56 partners) completed an ACE. Clinicians detected abnormalities in 34.3% (245/714) of individuals. The abnormalities were a median of 3 mm in diameter. Sensitivity and specificity of the ASE/ACE was 59.6% (95% CI 53.5-65.7%) and 80.2% (95% CI 76.6-83.8%), respectively. Overall concordance was 0.73 (95% CI 0.70-0.76) between ASE/ACE and DARE and increased with increasing anal canal lesion size (p = 0.02). Concordance was lower when participants were older and received ASE/ACE training from a lay person rather than a clinician. Interpretation: Sexual minority men/transgender women may self-detect SCCA when malignant lesions are much smaller than the current mean dimension at presentation of ≥30 mm. Funding: National Cancer Institute.

RESUMEN

Objective and Design: Forced anal examinations are used to prosecute sexual and gender minorities (SGM) in at least seven countries under the presumption that decreased sphincter tone, estimated by a finger inserted into the anal canal, can detect persons practicing receptive anal intercourse. In a cross-sectional analysis of the baseline data from a longitudinal study, we aimed to determine factors associated with sphincter tone and the accuracy of sphincter tonality to detect persons engaging in receptive anal intercourse. Setting: Clinicians in Chicago, Houston, and Milwaukee, USA conducted digital anal rectal examinations (DARE) on 838 participants, 94.0% of whom were cisgendered males. Clinicians used the Digital Rectal Examination Scoring System to score sphincter resting tone (RT) and squeeze tone (ST). On a separate survey, individuals reported their preferred position for anal intercourse: i.e., either always/mostly insertive anal intercourse, always/mostly receptive anal intercourse, or both receptive and insertive anal intercourse. Multivariable regression assessed factors associated with decreased sphincter tone while area under the Receiver Operating Characteristic curves (AUC) estimated the accuracy of sphincter tonality to detect receptive anal intercourse. Results: 11.3% had decreased RT (95/838) and 6.3% had decreased ST (53/838). The accuracy of DARE to detect any receptive anal intercourse was little better than random guessing (AUC 0.53, 95% CI 0.51 to 0.55, and AUC 0.51, 95% CI 0.49 to 0.53, respectively. RT and ST decreased with age regardless of sexual behavior (p trend <0.01 for both). Compared to individuals having always/mostly insertive anal intercourse, individuals having always/mostly receptive anal intercourse was associated with decreased RT, but not ST, while those equally preferring both insertive and receptive anal intercourse were not associated with decreased RT or ST. Conclusions: Decreased sphincter tone is uncommon among SGM who prefer receptive anal intercourse. Given virtually no accuracy, a finger inserted into the anus has no utility to detect individuals practicing receptive anal intercourse and thus should not be used as such. Trial registration: NCT04090060. Summary Box: What is already known on this topic: To gather evidence for prosecution of sexual and gender minorities, forced anal exams are used in multiple countries. The examination includes inserting the index finger into the anal canal to detect decreased sphincter tone which is considered evidence of receptive anal intercourse. We found only two small studies (n= 58 and n=24) assessing factors associated with decreased sphincter tone and none assessing the accuracy of sphincter tone to detect sexual and gender minorities having receptive anal intercourse.What this study adds: Our study suggests that a finger inserted into the anal canal is not useful to detect a history of receptive anal intercourse. As such, the sexual practices of individuals cannot be known using a forced anal examination.
