ABSTRACT
Cervical cancer rates are disproportionately high among women living with the human immunodeficiency virus (wlhiv). Cervical cancer is preventable through hpv screening, regular Pap tests, and early cancer detection. Evidence indicates that hpv and cervical cancer screening are suboptimal among wlhiv, who face a myriad of access barriers. Considering that screening is an effective first-line defense to cervical cancer, we conducted a scoping review with the aim of gaining a better understanding about: (1) the knowledge and perceptions of hpv and cervical cancer screening among wlhiv; and (2) the acceptability of self-sampling for hpv among wlhiv. We searched five electronic databases for peer-reviewed articles that were published in English within the last ten years, reported on studies with hiv-positive women who were aged 16 or older, and satisfied the topics of the review. A total of 621 articles were found. After accounting for duplicates and unmet criteria, 17 articles and 1 abstract, reporting on studies in the United States and Africa, were included in this review. The review highlighted that most wlhiv had inadequate knowledge of hpv transmission and cervical cancer prevention, which influenced their perceptions of risk and susceptibility. Screening barriers included misconceptions about Pap tests, fear of diagnosis of serious illness, perceived pain, embarrassment, bodily modesty, and limited access to female health care providers. This review also affirms that self-sampling is an acceptable and promising screening option for wlhiv. Implications for policy, research, and practice are discussed.
ABSTRACT
Human papillomavirus (hpv) infection is the cause of anal squamous cell cancer (ascc) in 80% of cases. Available research has also shown high prevalence of anal hpv infection among men who have sex with men (msm). However, hpv vaccination is low among msm in Canada. In light of this information, we conducted a scoping review with the aim of exploring (1) the knowledge of hpv and anal cancer among hiv-positive msm and (2) the acceptability of hpv and anal cancer self-sampling in this population. In conducting the review, we searched five electronic databases for peer-reviewed articles and abstracts published in English, between 2007 and 2017. A total of 803 articles were retrieved; after accounting for duplicates (n=40) and unmet criteria (n=754), a total of 794 articles were excluded. A final total of nine articles were used in this review. Results of this review show that hiv-positive msm have limited knowledge regarding the risks of anal cancer associated with hiv and hpv coinfection. Furthermore, there is limited research on hpv and anal cancer self-sampling in this population. However, the review of available studies suggested that hiv-positive msm were open to anal cancer self-sampling. It also identified potential barriers to self-sampling. In conclusion, we provide suggestions and future directions for policy-makers and educators to develop inclusive and accessible strategies to reach hiv-positive msm regarding anal cancer education and self-screening.
