Glandular neoplasia and borderline endocervical reporting rates before and after conversion to the SurePathTM liquid‐based cytology (LBC) system

Abstract

Reporting rates for glandular neoplasia in 464,754 cervical samples reported at six laboratories in 12-month periods before and after the implementation of Surepath™ LBC processing are compared. The introduction of LBC processing is seen to have resulted in a significant (P = 0.001) increase in the detection rate for endocervical glandular neoplasia (from 2.2 per 10,000 tests to 3.9 per 10,000) while maintaining high levels of reporting specificity. An observed fall in the number of samples reported as showing borderline glandular neoplasia falls short of statistical significance, and the reporting of possible endometrial and 'other' glandular abnormalities appears to be unaffected. The underlying reasons for the observed improvement in detection of endocervical glandular neoplasia are discussed.
