Aim:
Loop electrosurgical excisional procedure (LEEP) is a major treatment method for cervical precancerous lesions. However, recurrence rates were estimated to be 15%, and the risk is increased if a surgical margin is involved by dysplastic cells. This study aimed to identify the risk factors for recurrence of cervical precancerous lesions in patients with positive margins.
Methods:
We retrospectively reviewed medical records of patients who underwent LEEP between 2012 and 2014 and had a positive surgical margin. Clinicopathologic factors were collected, including age, parity, menopausal status, smoking, human papilloma virus infection, results of cytology/biopsy/LEEP, and specimen size and volume.
Results:
A total of 117 patients with positive margins were included, and 26 (22.2%) patients had recurrence. According to a multivariate analysis, the recurrence rates were significantly higher in parous women (adjusted hazard ratio [HR], 2.92; 95% confidence interval [CI], 1.00-8.49), but positive margins at the exocervix (adjusted HR, 0.39; 95% CI, 0.17-0.91) and volume ≥4000 mm3 (adjusted HR, 0.36; 95% CI, 0.16-0.82) showed negative correlation.
Conclusions:
The risk of recurrence for cervical precancerous lesions increased in patients with a history of previous delivery, positive margin at the endocervix, and specimen volume of LEEP <4000 mm3 . These results could help gynecologists determine optimal treatment options for patients with positive margins.
