Abstract
OBJECTIVE: The 2001 Bethesda System for Reporting Cervical Cytology includes documenting 'endometrial cells in women ≥40 years of age' (E40) to help identify endometrial carcinoma (EC) on a Papanicolaou (Pap) test. The 2014 Bethesda System for Reporting Cervical Cytology raises the threshold to ≥45 years of age (E45). As many of these women are menstruating, routine biopsy after E40, or even E45, may lead to unnecessary procedures for benign endometrial cells. Establishing a different age threshold in combination with other clinical findings may help to guide management. METHODS: A retrospective chart review was performed on consecutive EC specimens and E40 Pap tests. Clinical, pathological data such as age, biopsy diagnosis, FIGO grade and the time of the last Pap test, Pap test diagnosis and resection diagnosis, depth of invasion, stage and metastases were recorded. RESULTS: Sixty-three EC cases had prior Pap smears, with the following diagnoses: negative for an intraepithelial lesion or malignancy (n = 27), atypical glandular cells, not otherwise specified (AGC, NOS) (n = 14), adenocarcinoma (n = 10) and E40 (n = 1; 51 years). Six hundred and forty-two E40 cases had 138 (21.5%) biopsies and/or hysterectomies. Out of the 138 cases, two (1.4%) had EC (both 51 years; postmenopausal), one had complex hyperplasia with atypia (52 years; abnormal uterine bleeding), and eight had hyperplasia without atypia. CONCLUSIONS: In asymptomatic women less than 50 years, E40 correlated with benign, non-hyperplastic endometrium. However, post-menopausal women with E40 had a risk of EC. Perhaps endometrial cells should only be reported in post-menopausal women or women greater than or equal to 50 years of age.
