Summary
New guidelines offer evidence-based management for cervical cytologic abnormalities. Human papillomavirus testing is preferred for atypical squamous cells when using liquid-based cytology, guiding cervical cancer screening.
Area of Science:
- Gynecology
- Oncology
- Pathology
Background:
- The American Society for Colposcopy and Cervical Pathology established 2001 guidelines for managing cervical cytologic abnormalities.
- These guidelines integrate the Bethesda System 2001 terminology and data from key studies.
Purpose of the Study:
- To formulate evidence-based recommendations for cervical abnormality management.
- To grade recommendations by strength and evidence quality, incorporating specific terminology for management options.
Main Methods:
- Utilized data from randomized studies on atypical squamous cells, low-grade intraepithelial lesions, human papillomavirus (HPV) testing, and liquid-based cytology.
- Assessed triage recommendation effectiveness by the detection rate of grade 2 and 3 cervical intraepithelial neoplasia (CIN).
Main Results:
- For atypical squamous cells of undetermined significance, colposcopy, repeat cytology, and HPV DNA testing are options; HPV DNA testing is preferred with liquid-based cytology.
- Colposcopy is recommended for "atypical squamous cells-cannot rule out high-grade intraepithelial lesion."
- Low-grade squamous intraepithelial lesions require colposcopy; high-grade lesions necessitate colposcopy and endocervical assessment.
Conclusions:
- Colposcopy and endocervical sampling are advised for all atypical glandular cells.
- Endometrial sampling and colposcopy are recommended for women over 35 with atypical glandular cells or younger women with unexplained bleeding.
- Atypical glandular cells-favor neoplasia or adenocarcinoma-in-situ, without invasive disease, warrant a diagnostic excisional procedure, preferably cold-knife conization.
