Introduction
Anal cancer, though relatively rare, is on the riseespecially among women with high-grade cervical intraepithelial neoplasia (CIN II and CIN III). This compelling study from Brazil explores the potential benefits of incorporating anal cytology into gynecological evaluations for such patients.

Anal Cytology and Cervical Lesions The Overlap
Human Papillomavirus (HPV) is a key risk factor for both cervical and anal cancers. Despite shared embryological and histological features between the anal and cervical canals, screening for anal neoplasms in immunocompetent women remains uncommon. This study presents crucial findings that could influence gynecological protocols worldwide.
Study Summary and Key Findings
This prospective, cross-sectional clinical study analyzed 150 women aged 18 to 65:
- 76 patients had histologically confirmed high-grade cervical lesions CIN II/III
- 74 patients served as a control group with no such lesions.
Key Variables Considered
- Age, tobacco and alcohol use, sexual history, STD history, menopause, contraceptive use, and more.
Highlights:
- No significant difference in abnormal anal cytology between study and control groups.
- However, alcohol consumption and smoking were significantly more common in the CIN II/III group.
- Use of contraceptives also showed higher prevalence among affected individuals.
- Anal sex and multiple sexual partners showed limited statistical significance.

Implications for Clinical Practice
Since the Pap smear is already a routine procedure, introducing anal cytology simultaneously could improve early detection of anal intraepithelial neoplasiaan often missed yet treatable precursor to anal cancer.
The American Society for Colposcopy and Cervical Pathology ASCCP recommends enhanced monitoring of high-risk women, but does not yet standardize anal cytology as part of cervical lesion care. This research may help change that.
