BACKGROUND: Currently, there is no standardized follow-up protocol for patients who undergo laser conization. Therefore, we retrospectively investigated the clinical outcomes of laser conization in patients with high-grade cervical intraepithelial neoplasia 2-3 (CIN 2-3) and microinvasive squamous cell carcinoma and assessed the risks of residual and recurrent lesions of the cervix uteri.
METHODS: The medical and pathological records of 91 patients with CIN 2, 580 with CIN 3 and 73 with microinvasive cervical cancer (MIC) who underwent laser conization between January 2000 and December 2011 were retrospectively reviewed.
RESULTS: Positive margins increased with the extent of disease and were observed in 5.5%, 8.9% and 16.4% patients with CIN 2, CIN 3 and MIC, respectively, while residual or recurrent disease was observed in 0%, 3.2% and 13.6% patients, respectively. Examination of specimens obtained through postconization biopsy or hysterectomy revealed that 1.5% and 20% patients with negative and positive margins, respectively, were diagnosed with residual or recurrent lesions. Among patients who were conservatively managed after conization, seven with CIN 3 exhibited residual or recurrent disease, as evidenced by abnormal cytological findings, within 2 years after conization.
CONCLUSIONS: Continuous follow-up by cytology and colposcopy, particularly during the first 2 years after conization, can effectively detect early residual or recurrent disease in CIN 3 and MIC patients, regardless of their margin status.
