Summary
Histology diagnosis and time period significantly influence cervical cone margin involvement. Endocervical margin positivity is also linked to patient age and squamous-columnar junction visibility in CIN patients.
Area of Science:
- Gynecologic Oncology
- Cervical Pathology
- Surgical Pathology
Background:
- Cervical conization studies often focus on complications and outcomes, with less emphasis on factors determining positive cone margins.
- Understanding determinants of positive margins is crucial for effective treatment of cervical intraepithelial neoplasia (CIN).
Purpose of the Study:
- To evaluate factors associated with any cone margin involvement.
- To identify determinants of endocervical margin involvement specifically.
Main Methods:
- A retrospective study of 718 patients undergoing electrosurgical conization for CIN.
- Univariate analysis using chi-square tests and multivariate analysis using logistic regression models were employed.
Main Results:
- Overall cone margin involvement was 27%, strongly associated with histology diagnosis and time period.
- Endocervical margin involvement (14%) was associated with histology, time period, patient age, and squamous-columnar junction visibility.
- Cone width and depth did not show a protective effect on margin positivity.
Conclusions:
- Histology diagnosis and time period are key determinants of positive cone margins.
- Patient age and squamous-columnar junction visibility are also significant factors for endocervical margin positivity.
- Surgical parameters like cone width and depth do not appear to prevent positive margins.
