The cytologic features of endocervical neoplasia have been well-described for conventional and ThinPrep, but not for SurePath, methods. This study is designed to ascertain if cytological features are similar in SurePath specimens. Conventional, ThinPrep and SurePath specimens with either endocervical adenocarcinoma in situ or invasive endocervical adenocarcinoma were evaluated for architectural and cytological features previously described for endocervical neoplasia. A generalized linear model was used to assess the differences of ordinal multinomial data. Of 18 evaluated, the only features showing statistical differences were architectural: large groups of cells and single cells were more frequent in SurePath preparations and conventional smears. Feathering was more frequently noted in conventional smears. Individual cytological features were identical across all groups. Mitoses and apoptotic debris were seen with equal frequency in all preparations. The architectural and cytologic features of endocervical glandular neoplasia in liquid-based specimens show only subtle architectural differences when compared with conventional smears. Keeping these differences in mind, virtually the same criteria can be used to identify endocervical glandular lesions in all three specimen types. Diagn.
