Abstract
Objective. To compare the outcomes of patients with cervical adenocarcinoma in situ (ACIS) treated with
cold knife cone (CKC) biopsy or loop electrosurgical excision procedure (LEEP) for the treatment of cervical
adenocarcinoma in situ (ACIS).
Study design. This is a retrospective, population-based cohort study of Western Australian patients with
ACIS diagnosed between 2001 and 2012. Outcomes included pathological margin status and the incidence of
persistent or recurrent endocervical neoplasia (ACIS and adenocarcinoma) during follow-up (b12 months)
and surveillance (≥12 months) periods.
Results. The study group comprised 338 patients including 107 (32%) treated initially by LEEP and 231 (68%)
treated by CKC biopsy. The mean age was 33.2 years (range 18 to 76 years) and median follow-up interval was
3.6 years (range b1 year to 11.8 years). Overall, 27 (8.0%) patients had ACIS persistence/recurrencewhile 9 (2.7%)
were diagnosed with adenocarcinoma during the follow-up and surveillance periods. No patient died of cervical
cancer within the study period. There were no significant differences in the incidence of persistent and/or
recurrent endocervical neoplasia according to the type of excisional procedure. Patients with positive biopsy
margins were 3.4 times more likely to have disease persistence or recurrence.
Conclusion(s). LEEP and CKC biopsy appear equally effective in the treatment of ACIS for women wishing
to preserve fertility. Patients undergoing conservative management for ACIS should be closely monitored,
particularly if biopsy margins are positive in initial excision specimens. Patients and their clinicians should be
aware of the potential risks of residual and recurrent disease.
