The objective of this study is to assess the value of Loop Electrosurgical Conization (LEC) in the treatment of stage IA1 microinvasive squamous cell carcinoma (MIC) of the uterine cervix. Retrospectively, 82 patients with FIGO stage IA1 MIC, primarily treated with LEC on see and treat basis, were analyzed.
After the initial LEC, 16 patients received cytologic and colposcopic follow-up only, 66 patients underwent a second procedure (repeat LEC, Cold Knife Conization (CKC), or hysterectomy), and four patients underwent a third procedure (hysterectomy). In 63 patients (77%) no residual CIN 3 or MIC was present after the initial LEC. Treatment of residual CIN 3 or MIC was equally effective with a repeat LEC as with CKC. One patient defaulted follow-up and developed a recurrence in the vaginal vault and was treated with a radical hysterectomy.
LEC can be used as an alternative for CKC in treatment of patients with stage IA1 MIC. The advantage of LEC is that it can be performed as an outpatient procedure in addition to a diagnostic colposcopy and does not require a major anesthetic. Only a small number of patients will need a more extensive procedure.
