Women with International Federation of Gynecology and Obstetrics stage 1A1 cervical carcinoma were evaluated to determine whether repeat excision for large loop excision transformation zone margins positive with cervical intraepithelial neoplasia (CIN) had been undertaken according to the National Health Service Cervical Screening Programme guidelines and if deviations from guidelines adversely affected patient outcome.

Materials and Methods

We retrospectively studied patients with 1A1 cervical carcinoma treated in our service between May 2010 and July 2015 to determine whether NHSCSP guidelines (May 2010) were followed. This states that if the invasive disease is excised but CIN extends to the excision margin, then a repeat large loop excision transformation zone should be undertaken to exclude further invasive disease and to confirm excision of CIN.


Seventeen patients were identified. In one, neither the invasive lesion nor CIN was fully excised. In 5, the lesion and CIN were fully excised. In eleven, the invasive lesion was excised, but CIN was present at a margin. Of these 11 patients, none opted for a repeat excision. All 11 patients had negative cytology at first follow-up (negative up to 4 years [median = 2 years]).


Our outcomes suggest that it may not be necessary to perform a repeat excision for CIN present at the excision margin in women with 1A1 cervical carcinoma when CIN is present either at the endocervical, deep stromal, or ectocervical margin, as long as the invasive focus is fully excised, and patients have been fully counseled and have regular cytology follow-up. This may be an alternative for patients wanting to minimize the risks to fertility posed by repeat excision.
