BACKGROUND: The purpose of this study was to clarify the clinicopathological characteristics of, and the clinical approach used to identify, atypical glandular cells (AGCs) in Japan based on cervical cytology screening.
OBJECTIVES: This study included 1,254 patients with AGCs who underwent cervical cytology.
METHOD: Data from patients with AGCs were used to examine the practical management of AGCs and the histological results.
RESULTS: The incidence of AGCs was 0.20% (1,254/614,791). The 1,254 AGC cases included 859 endocervical cells not otherwise specified (NOS), 3 glandular cells NOS, 91 endocervical cells favor neoplasia (FN), and 301 atypical endometrial cells (AEMCs). Among the 1,254 AGC patients, the histological diagnosis was benign in 666 (53.1%), cervical intraepithelial neoplasia (CIN) 1 in 60 (4.8%), CIN2 in 31 (2.5%), CIN3 in 52 (4.1%), squamous cell carcinoma in 19 (1.5%), adenocarcinoma in situ in 39 (3.1%), cervical adenocarcinoma in 106 (8.5%), endometrial carcinoma in 209 (16.7%), ovarian cancer in 26 (2.1%), other malignancy in 4 (0.3%), and other under follow-up in 42 (3.3%). When the 1,254 AGC patients were divided into three medical intervention degrees according to histology, AGC-NOS, AGC-FN, and AEMC required no medical intervention in 78.7, 13.2, and 25.9% (678, 12, and 78) of the patients, cervical cone resection in 13.0, 9.9, and 0.3% (112, 9, and 1) of the patients, and radical laparotomy for invasive cancer in 8.3, 76.9, and 73.8% (72, 70, and 222) of the patients, respectively.
CONCLUSIONS: Our histological results supported the medical interventions applied for AGC diagnosis and treatment. AGC cases require careful histological evaluation.
