Summary
Pregnancy does not affect the accuracy of colposcopy and directed biopsy for cervical cancer screening. Awareness of pregnancy-related changes ensures reliable results for pregnant individuals.
Area of Science:
- Gynecology
- Obstetrics
- Cervical Pathology
Background:
- Pregnancy can alter cervical tissue, potentially impacting diagnostic accuracy.
- Evaluating the reliability of cervical cancer screening methods during pregnancy is crucial.
Purpose of the Study:
- To assess the reliability of cytology, colposcopy, and directed biopsy in pregnant women.
- To compare diagnostic accuracy in pregnancy versus a matched non-pregnant control group.
Main Methods:
- A colposcopist examined 117 pregnant patients and 234 non-pregnant controls.
- Final pathology was ascertained for all participants.
- Concordance between diagnostic methods and final pathology was analyzed.
Main Results:
- Pregnancy did not significantly alter the reliability of cytology, colposcopy, or directed biopsy.
- Unsatisfactory colposcopy was less frequent in pregnant patients (12.8%) than controls (23.1%).
- High concordance was observed between directed biopsy histology and final diagnosis (83.7%-95.9%).
Conclusions:
- Physiological changes during pregnancy do not significantly impact colposcopy and directed biopsy reliability.
- Awareness of pregnancy-specific challenges and avoiding overreaction to accentuated patterns are key for accurate diagnosis.
- The study supports the continued use of these methods for cervical cancer screening in pregnancy.
