Abstract
Background Persons living with HIV (PLWH) have a higher risk of persistent infection with human papillomavirus (HPV) and anal cancer. We evaluated knowledge and awareness of HPV infection and risk factors for anal cancer among PLWH in Puerto Rico (PR). Methods Data from a cross-sectional study (2020-2021) were analyzed (n=212). Inclusion criteria included PLWH, aged ≥ 26 years, and living in PR. Telephone interviews collected information on sociodemographic, lifestyle and clinical characteristics. Two 13-item scales were used to assess knowledge of HPV and anal cancer risk factors; adequate knowledge for both scales were defined as scoring >70%. Logistic regression models using generalized linear models were used to determine the association between 1) HPV infection awareness, 2) HPV infection knowledge, and 3) Anal cancer risk factors knowledge. Results The median age was 54 years (IQR: 46,58), 67.5% were male, 71.7% reported having an income <$20,000, and 54.3% had an education level of more than high school. HPV awareness was high (82.1%), but only 40.2% and 3.8% had adequate knowledge of HPV and anal cancer risk factors, respectively. In adjusted logistic regression models, men who have sex with men (OR: 1.26, 95%CI: 1.07-1.47) and women (OR: 1.35, 95%CI: 1.15-1.59) aged ≥50 years had higher odds of HPV awareness than heterosexual men in that age group. Moreover, those with history of anal Pap test aged <50 years had more HPV awareness (OR 1.34, 95%CI: 1.08-1.66) than their counterparts. Adequate HPV knowledge was higher among participants with an education level of more than high-school (OR:1.28, 95%CI: 1.10-1.50) and with a history of HPV diagnosis (OR:1.33, 95%CI: 1.08-1.65) than their counterparts. In addition, people with good/very good/excellent health perception had higher odds of HPV knowledge (OR:1.23, 95%CI: 1.03-1.47) than those who reported poor/regular health perception. For anal cancer risk factors, PLWH for ≥15 years had increased odds of having adequate knowledge (OR:1.07, 95%CI: 1.02-1.14) than their counterparts. Conclusions Despite high awareness of HPV, limited knowledge about HPV and anal cancer risk factors was observed among PLWH. Results from our study highlight the need for educational efforts within this population as an anal cancer prevention strategy.

Abstract
Background Anal cancer, mainly attributed to human papillomavirus (HPV) infection, is rising in prevalence among the general population in Pakistan. This study aimed to examine the knowledge, attitudes, and practices (KAP) towards anal cancer screening and HPV of the general population in Pakistan. Method We surveyed anal cancer KAP using social media and snowball sampling from December 2022 to May 2023. The questionnaire had 16 knowledge, 12 attitudes, 6 practice questions, and socio-demographic variables. We applied validity criteria for inclusion and exclusion and used cutoffs ≥50% for each KAP category. We analyzed data in R with Guttman's λ2 for reliability, did univariate and bivariate analysis, and reported frequencies, percentages, p-values, coefficients, odds ratios, and 95% confidence intervals. Results We surveyed 1620 people and discovered low awareness of HPV and anal cancer causes prevention, and screening (11%-24%), high stigma and embarrassment for screening (54%-70%), strong moral beliefs (89%), condom nonuse (91%), and low engagement in health services and programs (9.1%-14%). Knowledge (75.23%, OR = 1.0984, p = 0.05) was shaped by socio-demographic factors, attitude, and practice, with higher education enhancing knowledge (OR = 1.0984, p = 0.05). Attitude (78.45%, OR = 6.6052, p< 0.001) was influenced by socio-demographic factors, practice, and knowledge as well. Younger females, single, unemployed, students, living with more family members, earning more income, and residing in Islamabad had a more positive attitude (ORs from 1.0115 to 6.6052, p< 0.05), while religion did not affect attitude (p = 0.51). Practice (9.16%, OR = 0.1820, p< 0.001) was determined by socio-demographic factors, knowledge, and attitude. Older males, employed teachers, living with more family members, earning less income, and residing in Islamabad had better practice (ORs from 0.1323 to 3.8431, p< 0.05), but marital status and religion did not influence practice (p > 0.05). Conclusion Pakistani young adults need more education, awareness, health services, and programs on HPV and anal cancer, as they have low awareness, high stigma, and socio-cultural challenges. In addition, it is recommended for more research and policy initiatives are needed to address socio-cultural factors and increase anal Pap to overcome anal cancer.

Barriers and facilitators to anal cancer screening among people living with HIV in Puerto Rico. BMC Public Health 2023; 23:1940. [PMID: 37803344 PMCID: PMC10559598 DOI: 10.1186/s12889-023-16847-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 09/27/2023] [Indexed: 10/08/2023] Open
Abstract
BACKGROUND Anal cancer (AC) disproportionally affects people living with HIV (PLWH). Although there are no consensus-based AC screening guidelines, experts recommend anal pap as a primary screening tool in settings where high-resolution anoscopy (HRA) is available. We aimed to assess barriers and facilitators to anal cancer screening in a sample of Hispanic PLWH in Puerto Rico. METHODS To assess their knowledge and attitudes, we conducted a cross-sectional survey from 2020-2021 among PLWH in Puerto Rico (n = 212). Data was collected through a telephone interview that assessed information on sociodemographics, knowledge, and attitudes about AC, and the history of AC screening. The chi-square test, Fisher exact test, and logistic regression models were used to assess factors associated with screening uptake. RESULTS Anal Pap and HRA awareness were 60.4% and 30.7%, respectively. Anal Pap and HRA uptake was 51.5% and 19.3%, respectively. The most common barriers for anal Pap and HRA were lack of knowledge about the test and lack of physician recommendation. MSM were more likely to have heard of anal Pap (OR: 2.15, 95% CI:1.30-3.54) than MSW. MSM (OR: 3.04, 95% CI: 1.79-5.19) and women (OR: 3.00, 95% CI: 1.72-5.20) were also more likely to have undergone anal Pap. Similarly, individuals with a history of genital warts were more likely to have heard of anal Pap and HRA and have undergone anal Pap and HRA. Awareness of where to go for concerns about anal health was positively associated with having received anal Pap and HRA. CONCLUSIONS With emerging evidence on the effectiveness of screening and treatment for anal cancer, several organizations are steering toward generating consensus-based anal cancer screening recommendations. Our study provides foundational data on barriers and facilitators to anal cancer screening in Puerto Rico that will be critical to informing screening implementation in this US territory.

Abstract
OBJECTIVE Anal cancer screening has been recommended for women with lower genital tract neoplasia, lupus, Crohn disease, HIV, and/or organ transplantation recipients. This study described and compared knowledge, attitudes, and experiences related to anal cancer and anal cancer screening between women at high risk for anal cancer and their counterparts. METHODS This is a cross-sectional study within colposcopy and gynecology oncology clinics in Puerto Rico; 278 women 21 years or older and with prior diagnosis of gynecological neoplasia completed an interviewer-administered questionnaire. Women were categorized according to their medical history as being high risk or non-high risk for anal cancer. The high-risk group included women with a history of lower genital tract neoplasia, lupus, Crohn disease, HIV, and/or organ transplantation. RESULTS Overall, 40.7% of the study population were at high risk for developing anal cancer. History of anal cancer screening was low among high-risk and non-high-risk women (11.5% vs 5.6%, p > .05). Less than 1% of all women reported to have had a high-resolution anoscopy. Most women (87.6%) had little knowledge about anal Pap test but were willing to have one if their doctors recommended it (96.5%). No major differences in knowledge, attitudes, or screening history were observed between high-risk and non-high-risk women. CONCLUSIONS Although experts do not recommend routine anal cancer screening for the general population, they do recommend it for women within certain high-risk groups. Study findings highlight the importance of increasing education and awareness of anal cancer among high-risk patients and physicians, to promote better preventive methods, achieve early detection, and improve disease outcomes.

Abstract
OBJECTIVES The aims of the study were (1) to describe anal cancer knowledge, perceived risk, screening barriers, and acceptability of sample self-collection among women living with HIV (WLWH) at an integrated safety-net system and (2) to describe differences in demographic and psychosocial variables among a subsample of WLWH with a history of abnormal cervical cytology results versus those with normal results. MATERIALS AND METHODS We conducted telephone surveys with English- and Spanish-speaking WLWH (N = 99) and used electronic health record data to extract insurance type, CD4+ cell count, RNA viral load, and cervical cytology results. We calculated descriptive statistics for participant demographics, HIV laboratory results, and psychosocial variables. Among the subsample of women who completed a recent cervical Pap, we used Fisher exact test to assess differences in demographic variables, CD4+ counts, RNA viral loads, knowledge, awareness, acceptability, and perceived risk by cervical cytology results. RESULTS Most participants (70%) reported knowing nothing about anal cancer; 28% correctly responded that HIV increases one's chance of getting anal cancer. Most (68%) never heard of an anal Pap test. Forty percent would get an anal Pap if they could self-collect the sample, whereas 59% were neutral or disagreed. The 2 most commonly cited barriers to obtaining an anal Pap were "I do not know enough about it" (n = 15) and "It might hurt" (n = 9). CONCLUSIONS This study highlights a gap in knowledge and awareness among WLWH regarding their heightened risk for anal cancer. It indicates the need for health education and suggests an opportunity for a self-collection intervention.

Abstract
Background Anal cancer is a rare disease, constituting 0.5% of new cancer cases in the United States. The most common subtype is squamous cell carcinoma (scc). Studies in several developed nations have reported on an increasing incidence of anal cancer in recent decades, and various risk factors pertaining to the pathogenesis of the disease have been identified, including infection with the human papillomavirus, tobacco use, and immunosuppression. The epidemiology and distribution of anal scc throughout Canada remain poorly understood, however. Methods Using 3 population-based cancer registries, a retrospective analysis of demographic data across Canada for 1992-2010 was performed. The incidence and mortality for anal scc was examined at the levels of provinces, cities, and the forward sortation area (FSA) component (first 3 characters) of postal codes. Results During 1992-2010, 3720 individuals were diagnosed with anal scc in Canada; 64% were women. The overall national incidence rate was 6.3 cases per million population per year, with an average age at diagnosis of 60.4 years. The incidence increased over time, with significantly higher incidence rates documented in British Columbia and Nova Scotia (9.3 cases per million population each). Closer examination revealed clustering of cases in various urban centres and self-identified lgbtq communities in Toronto, Montreal, and Vancouver. Discussion This study provides, for the first time, a comprehensive analysis of the burden of anal scc in Canada, identifying susceptible populations and shedding light onto novel avenues of research to lower the incidence of anal cancer throughout the country.

Abstract
Background Anal cancer is potentially preventable through screening. For screening to be implemented, the screening procedures must be acceptable to the affected population. The objective of the present study was to measure the acceptability of currently available anal cancer screening tests in a population of women living with hiv who had experienced the tests. Methods The evva study ("Evaluation of Human Immunodeficiency Virus, Human Papillomavirus, and Anal Intraepithelial Neoplasia in Women") is a prospective cohort study of adult women living with hiv in Montreal, Quebec. Participants were screened with cervical or anal hpv testing and cervical or anal cytology every 6 months for 2 years. High-resolution anoscopy (hra) and digital anal rectal examination (dare) were also performed systematically, with biopsies, at baseline and at 2 years. An acceptability questionnaire was administered at the final visit or at study withdrawal. Results Of 124 women who completed the acceptability questionnaire, most considered screening "an absolute necessity" in routine care for all women living with hiv [77%; 95% confidence interval (ci): 69% to 84%]. Yearly anal cytology or anal hpv testing was considered very acceptable by 81% (95% ci: 73% to 88%); hra every 2 years was considered very acceptable by 84% (95% ci: 77% to 90%); and yearly dare was considered very acceptable by 87% (95% ci: 79% to 92%). Acceptability increased to more than 95% with a longer proposed time interval. Pain was the main reason for lower acceptability. Conclusions Most participating women considered anal cancer screening necessary and very acceptable. Longer screening intervals and adequate pain management could further increase the acceptability of repeated screening.

Abstract
INTRODUCTION Anal cytology (AC) can be used as a screening tool for detection of anal HPV associated lesions, mainly in men who have sex with men and in immunosuppressed patients. Our aim is to review our experience with AC in women. MATERIAL & METHODS We have retrospectively reviewed all AC diagnosed between 2010-2017 in a single tertiary hospital (n = 644) and selected those performed in women (n = 158). RESULTS 24.53% of AC were performed in women. 14.7% of all women were HIV positive and 56.7% referred anal intercourse. Squamous lesions were found in 27.2% of women, most of them ASCUS and LSIL (14% and 11.5%). HPV DNA was detected in 38.6% of patients, and 63.9% of them showed positivity for multiple high-risk types. Anal biopsy showed high grade lesions in 20% of biopsied patients. We observed a significant relationship between HPV status and receptive anal sex, and the association between HPV status and anal histological diagnosis tended to significance. Sensitivity, specificity, negative predictive value and positive predictive value for anal cytology were 57%; 83%; 28% and 94%, respectively. 70.9% of women had synchronous cervical cytology, and squamous cervical lesions were detected in 46.4% of the cases, most of them LSIL or ASCUS (21.4% and 15.2%). We did not confirm a significant association between cytological diagnosis of cervical and anal samples. CONCLUSIONS AC is less widely used in women than in homosexual men. However, women show important rates of anal lesions, regardless of their HIV status. More studies should be performed to assess the potential impact of screening protocols in this population.

[PMID: 27095188 DOI: 10.1016/j.ygyno.2016.04.015] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2016] [Revised: 04/12/2016] [Accepted: 04/15/2016] [Indexed: 01/20/2023]
Abstract
OBJECTIVE To compare the prevalence of abnormal anal cytology, high-risk anal HPV and biopsy proven anal dysplasia among women with a history of lower genital tract malignancy compared to those with dysplasia. METHODS A prospective cohort study was performed from December 2012 to February 2014 at outpatient clinics at an academic medical center. Women with a history of high-grade cervical, vulvar, or vaginal dysplasia, or malignancy were recruited. Anal cytology and HPV genotyping were performed. All women with abnormal anal cytology were referred for high-resolution anoscopy and biopsy. RESULTS Sixty-seven women had a lower genital tract malignancy and 123 had a history of genital dysplasia. Average age in the malignancy group was 52.6years (range 27-86) versus 43.5years (range 21-81) in the dysplasia group (p<0.0002). Similar rates of anal dysplasia were seen in both groups, 12.99% (10 cases) in the malignancy group, versus 12.20% (15) in the dysplasia group (p=1.0). Six women in the malignancy group had anal intraepithelial neoplasia (AIN2+) compared to 2 in the dysplasia group (p=0.03). CONCLUSIONS We found high rates of abnormal anal cytology and HPV in women with lower genital tract dysplasia and malignancy. We also found high rates of anal dysplasia in both groups with a trend towards increased rate in those women with history of genital malignancy. Since precancerous anal lesions are detectable and treatable, anal cancer screening may be potentially useful in both of these higher risk groups.

Abstract
This review focuses on the early diagnosis of anal cancer and its precursor lesions through routine screening. A number of risk-stratification strategies as well as screening techniques have been suggested, and currently little consensus exists among national societies. Much of the current clinical rationale for the prevention of anal cancer derives from the similar tumor biology of cervical cancer and the successful use of routine screening to identify cervical cancer and its precursors early in the disease process. It is thought that such a strategy of identifying early anal intraepithelial neoplasia will reduce the incidence of invasive anal cancer. The low prevalence of anal cancer in the general population prevents the use of routine screening. However, routine screening of selected populations has been shown to be a more promising strategy. Potential screening modalities include digital anorectal exam, anal Papanicolaou testing, human papilloma virus co-testing, and high-resolution anoscopy. Additional research associating high-grade dysplasia treatment with anal cancer prevention as well as direct comparisons of screening regimens is necessary to develop further anal cancer screening recommendations.
