BACKGROUND: Patients with a biopsy-confirmed cervical intraepithelial neoplasia 2 and 3 have an increased risk of disease progression to invasive cancer and should be treated with an excisional method. However, after treatment with an excisional method, a high-grade residual lesion may remain in patients with positive surgical margins. We aimed to investigate the risk factors for a residual lesion in patients with a positive surgical margin after cervical cold knife conization.
METHODS: Records of 1008 patients who underwent conization at a tertiary gynecological cancer center were retrospectively reviewed. One hundred and thirteen patients with a positive surgical margin after cold knife conization were included in the study. We have retrospectively analyzed the characteristics of the patients treated with re-conization or hysterectomy.
RESULTS: Residual disease was identified in 57 (50.4%) patients. The mean age of the patients with residual disease was 42.47 ± 8.75 years. Age greater than 35 years (P = 0.002; OR, 4.926; 95%CI [Confidence Interval] - 1.681-14.441), more than one involved quadrant (P = 0.003; OR, 3.200; 95% CI - 1.466-6.987), and glandular involvement (P = 0.002; OR, 3.348; 95% CI - 1.544-7.263) were risk factors for residual disease. The rate of high-grade lesion positivity in post-conization endocervical biopsy at initial conization was similar between patients with and without residual disease (P = 0.16). The final pathology of the residual disease was microinvasive cancer in four patients (3.5%) and invasive cancer in one patient (0.9%).
CONCLUSION: In conclusion, residual disease is found in about half of the patients with a positive surgical margin. In particular, we found that age greater than 35 years, glandular involvement, and more than 1 involved quadrant were associated with the residual disease.
