Sumario: | OBJECTIVE: To achieve optimal depth for negative margin cones after loop electrosurgical excision procedures (LEEP) for cervical dysplasia. MATERIAL AND METHODS: Retrospective cohort analysis of LEEP cones of 201 patients with cervical dysplasia during a four-year period. Analysed cones were divided into two different groups: cones with negative margins without dysplasia, and cones with margins positive for dysplasia. In order to determine the cut-off value of the depth of the resected cones, receiver operating characteristic (ROC) analysis was performed. RESULTS: Negative margins were found in 71.0% (n=49) of all cones, whereas positive margins were reported in 29.0% (n=20). Negative margin cones were achieved in 100% with a cone depth of ≥20 mm. A resection depth between 10-19.9 mm led to 73.0% negative margin cones. Calculation of cone volume shows for 2.0 cm3, a sensitivity of 79% and a specificity of 64%. Statistical analysis using an ROC model showed p=0.002. CONCLUSION: Forth greatest safety of patients, cone depths from LEEPs for cervical dysplasia should be ≥20 mm to achieve negative margins. |
