Clinicopathological features of atypical glandular cells, not otherwise specified, on cervicovaginal pap smears.

Abstract

The Papanicolaou (Pap) smear test is a standard screening test that detects cervical lesions and cancers. In this multicentric study, we performed a retrospective analysis of cytological results associated with atypical glandular cells, not otherwise specified (AGC-NOS). We retrospectively reviewed Pap smear tests that resulted as AGC-NOS. A total of 254 women who underwent colposcopy due to a Pap smear result of AGC-NOS were included the study between 2003 and 2021. The ages, Pap smear results, HPV results if any, colposcopic biopsy results, endocervical and endometrial pathology results, and management of these patients were analysed. Two hundred fifty-four patients with AGC-NOS Pap smear results were included in the study. A total of 70 (27.6%) patients had cervical and endometrial premalignant or malignant lesions. Malignancy was observed in 17 (6.7%) patients (endometrium, n = 11 [4.3%]; cervix, n = 6 [2.4%]). Isolated premalignant or malignant lesions of the cervix and endometrium were detected in 57 (22.4%) and 12 (4.7%) patients, respectively. Patients diagnosed with AGC-NOS should undergo a careful evaluation with all clinicopathological features. Because cancer of the cervix and endometrium is not rare in patients diagnosed with AGC-NOS, colposcopic examination with endocervical sampling should be a priority based on a cervicovaginal smear. Endometrial sampling is also required according to the patient's clinic, age, and examination characteristics.
