Predictors of recurrence in high-grade cervical lesions and a plan of management.

UNLABELLED: PRÉCIS: Positive endocervical margins are an important predictor of recurrence in high-grade cervical lesions, and though they do not always warrant retreatment, closer surveillance is recommended.

OBJECTIVE: To identify predictors of recurrence and persistence of high-grade cervical dysplasia and to determine appropriate follow-up.

DESIGN: prospective pilot study.

SETTING: Gynaecological surgical center.

POPULATION: Three hundred fifty-two patients were treated between 1999 and 2002 for high-grade lesions.

METHODS: According to the accessibility of the transformation zone and the degree of dysplasia, patients were treated either by conization or by loop electrosurgical excision procedure (LEEP). Follow-up comprised colposcopy and Pap-smear screening 4-6 months after treatment as well as high-risk human papillomavirus (HR-HPV) testing before and after treatment.

MAIN OUTCOME MEASURES: underscore predictors of recurrence and propose a treatment flowchart for both management and follow-up.

RESULTS: Of the 352 patients, 37 (10.5%) had true recurrence 6 months after initial surgical treatment and 6 patients (1.7%) had persistent lesions. Overall, 43 patients (12.2%) were considered as having recurrent disease. Patients were followed up for 5 years with a mean of 73 months. The most important predictor of recurrence was a positive HR-HPV test at 6 months postoperatively (odds ratio 38.8, 95% confidence interval 14.09, 107.05). The second significant predictor was positive endocervical margins and the third was positive pre-treatment HPV typing. A positive post-treatment HPV test had a more significant influence on risk than a positive test before treatment.

CONCLUSION: In agreement with recent findings, our study supports the usefulness of the HR-HPV test in the follow-up of treated high-grade lesions, especially when excision margins were positive.
