Objective This study was performed to evaluate the significance of positive resection margins (RMs) with the loop electrosurgical excision procedure combined with cold coagulation (LEEP with CC) as a definitive treatment for patients with cervical intraepithelial neoplasia (CIN) and adenocarcinoma in-situ. Methods We retrospectively reviewed 467 patients who underwent LEEP with CC. A right-angled triangular loop in a single pass followed by a CC (120 °C) to the cone bed for 10 to 20 s was used. Pathology reports and clinical data were obtained and evaluated. Results Histopathology evaluation of LEEP tissue samples revealed the presence of CIN 1 in 69, CIN 2/3 in 366, AIS in 5 and invasive carcinoma in 16 (microinvasive squamous cell carcinoma (SCC) and invasive SCC, 13 and 3) patients. Margins were positive in 66 (14.5%) cases: 0 in CIN 1, 54 in CIN 2/3 (12.4%), 1 in AIS (20.0%) and 11 in microinvasive/invasive SCC (68.8%). Although 54 CIN2/3 patients with positive RMs did not undergo additional treatment, 1 of these (1.9%) was confirmed to have residual CIN3 at the first follow-up. Two of 8 (25.0%) microinvasive SCC patients with positive RMs were confirmed to have residual diseases (1 microinvasive SCC and 1 invasive SCC) after hysterectomy. Four out of 360 (1 positive RM, 3 negative RM) CIN cases recurred during the study period. Conclusions These results suggest that CIN patients with positive RMs after LEEP with CC may be followed up without additional treatment.

环形电切术联合冷凝治疗宫颈上皮内瘤变和原位腺癌:一种低残留/复发风险的可行治疗方法

目的 本研究旨在评估环形电切术联合冷凝(LEEP+CC)阳性切缘(RMs)作为宫颈上皮内瘤变(CIN)和原位腺癌患者明确治疗的意义。方法 我们回顾性分析了 467 例接受 LEEP 的 CC 患者。使用单程直角三角形环,然后使用 CC (120 °C) 到达锥床 10 至 20 秒。获得并评估病理报告和临床数据。结果 LEEP 组织样本的组织病理学评估显示,69 例患者存在 CIN 1,366 例患者存在 CIN 2/3,5 例患者存在 AIS,16 例患者存在浸润性癌(微浸润性鳞状细胞癌 (SCC) 和浸润性 SCC,13 例和 3 例)。66 例 (14.5%) 例中的边缘为阳性:CIN 1 中为 0,CIN 2/3 中 54 人(12.4%),AIS 中 1 人(20.0%)和微创/侵入性 SCC 中 11 人(68.8%)。尽管 54 名 RM 阳性的 CIN2/3 患者未接受额外治疗,但其中 1 名 (1.9%) 在第一次随访时被证实有残留 CIN3。8 名 RM 阳性的微创 SCC 患者中有 2 名(25.0%)在子宫切除术后被证实有残留疾病(1 名微创 SCC 和 1 名浸润性 SCC)。在研究期间,360 例(1 例阳性 RM,3 例阴性 RM)CIN 病例中有 4 例复发。结论 这些结果表明,LEEP 联合 CC 后 RM 阳性的 CIN 患者可以在不进行额外治疗的情况下进行随访。9%)在第一次随访时确认有残留的 CIN3。8 名 RM 阳性的微创 SCC 患者中有 2 名(25.0%)在子宫切除术后被证实有残留疾病(1 名微创 SCC 和 1 名浸润性 SCC)。在研究期间,360 例(1 例阳性 RM,3 例阴性 RM)CIN 病例中有 4 例复发。结论 这些结果表明,LEEP 联合 CC 后 RM 阳性的 CIN 患者可以在不进行额外治疗的情况下进行随访。9%)在第一次随访时确认有残留的 CIN3。8 名 RM 阳性的微创 SCC 患者中有 2 名(25.0%)在子宫切除术后被证实有残留疾病(1 名微创 SCC 和 1 名浸润性 SCC)。在研究期间,360 例(1 例阳性 RM,3 例阴性 RM)CIN 病例中有 4 例复发。结论 这些结果表明,LEEP 联合 CC 后 RM 阳性的 CIN 患者可以在不进行额外治疗的情况下进行随访。
