Abstract:
OBJECTIVE: To evaluate how resection margin involvement after LLETZ affect treatment of CIN and microinvasive cervical cancer, and several factors affecting the resection margin involvement. METHOD: Retrospective analysis was performed in 160 patients that underwent LLETZ at Gachon Medical College, Gil Medical Center from March, 1997 to September , 1998. The several factors affecting the resection margin involvement were analyzed. RESULT: The following results were obtained. 1. 127 patients were diagnosized finally with CIN, 30 patients with microinvasive SCC and 3 patients with chronic inflammation. 2. The rate of the negative resection margin involvement was 81% and that of the positive was 19%. 3. No case among 129 cases with the negative resection margin had residual lesion, but 9 cases among 31 cases with the positive resection margin had residual lesion. As a whole, the rate of residual lesion was 6.2%. 4. In CIN, 3 cases of 19 cases with the positive resection margin had residual lesion, but none with the negative resection margin had. 5. The degree of histopathology, glandular involvement, menopause, colposcopic evaluation were correlated with the resection margin involvement but delivery mode and HPV infection not correlated. CONCLUSION: LLETZ is a enough method to reduce unnecessary hysterectomy in the treatment of CIN, if followed up, in spite of the positive resection margin because of low rate of lesidual lesion, and is a effective method in the treatment of microinvasive cervical cancer when the case with negative resection margin and no lymphovascular invasion was followed up.
