Importance of anal cytology and screening for anal dysplasia in individuals living with HIV with an emphasis on women. Academic Article uri icon

Overview

abstract

  • BACKGROUND: The incidence of squamous cell carcinoma of the anal canal has been increasing in high-risk populations. To the authors' knowledge, there is no international consensus regarding screening for squamous cell carcinoma of the anal canal, but screening is commonly comprised of a Papanicolaou (Pap) test in combination with digital anorectal examination followed by high-resolution anoscopy if necessary. The current study focused on individuals living with HIV and particularly on women living with HIV. METHODS: In this 5-year retrospective study, the authors identified 5982 Pap tests, 1848 of which had follow-up biopsy within 6¬†months. The rate of atypical squamous cells of undetermined significance was 42%, and approximately 38.1% of cases with this interpretation were diagnosed as high-grade squamous intraepithelial lesions on follow-up biopsy. In addition, 82 women with anal cytology had long-term follow-up (>10¬†years) available. RESULTS: The authors investigated a relationship between cervicovaginal human papillomavirus (HPV) results, cervical pathology, CD4 T-cell count, and CD4/8 ratio with the anal cytology interpretation. A statistical correlation was noted between the CD4 count and the CD4/8 ratio and the presence of anal dysplasia. Nearly one-half of the women without cervicovaginal HPV positivity presented with anal dysplasia. CONCLUSIONS: The results of the current study demonstrated that, among women living with HIV, screening for anal dysplasia should not be eschewed, regardless of lower genital tract pathology and/or HPV status. To the authors' knowledge, the current study is the largest reported retrospective anal cytology cohort in individuals living with HIV.
