Microinvasive cervical carcinoma: a retrospective study of cases presenting to the Oxford Colposcopy Unit between 1989 and 1996

Abstract

This a retrospective analysis of 65 cases of microinvasive disease and 5-8 years of follow-up (mean 6.2 years), evaluating the effectiveness of cytology and colposcopy in the diagnosis of microinvasive disease and the role of conservative surgery in its management. Cervical cytology reports indicated disease more severe than CIN III in 23% of cases. A further 7% at colposcopy were thought to have possible invasive disease despite no indication from the smear report, this impression correlated with increasing depth of invasion (>1.40 mm).
