The oncological and obstetric outcomes of cervical squamous cell carcinoma at stage IA1 managed with the loop electrosurgical excision procedure

摘要

ObjectiveTo evaluate the efficacy and superiority of loop electrosurgical excision procedure (LEEP) in managing stage IA1 cervical microinvasive squamous cell carcinoma (MISCC) without lymph-vascular space invasion (LVSI).Materials and methodsThe oncological and reproductive outcomes of a series of patients affected by stage IA1 MISCC without LVSI, initially treated by LEEP between February 2006 and December 2017, were retrospectively reviewed.ResultsUltimately, 109 patients were included. The mean age at diagnosis was 35.4 years old, and 36 patients were nulliparous. Multifocal lesions were identified in 15 patients (13.8%). The mean cone depth was 17.4?mm. Resection margins were positive/unevaluable and negative in 26 (23.9%) and 83 (76.1%) cases, respectively. Among cases undergoing salvage treatments, the residual disease rate for patients with positive/unevaluable margins was significantly higher than those with negative margins (P?=?0.003). During the follow-up period of 43.0?±?28.9 months, no relapse was identified. Fifteen of 20 patients (75.0%) conceived successfully, with a full-term live birth rate of 93.3%.ConclusionsFor stage IA1 MISCC without LVSI unexpectedly found in a loop excision, initial LEEP with clear margin is efficient and adequate. For cases with multifocal MISCC, or for those young patients who wish to become pregnant in the future, LEEP is the optimal choice.
