- Abstract
Objective: We aimed to develop and reinforce a clinical management regimen for atypical endometrial cell (ATEC) categories within the descriptive reporting format for endometrial cytology. Methods: Between January 2013 and December 2014, 215 samples, for which histological examination was performed immediately or within 3 months after cytology, were cytologically diagnosed as ATEC. For these samples, the medical records were retrospectively reviewed to identify risk factors for malignancy. Results: Among 152 samples diagnosed as ATEC, of undetermined significance, 19 (12.5%) were malignant. In the younger group (age <55 years), the χ2 values of body mass index (BMI) ≥25 kg/m2 (5.85), gravidity (5.64) and parity (5.15) were relatively high, suggesting that these were risk factors for malignancy. Of the nulligravida patients, those with BMI ≥25 kg/m2, 28% were diagnosed with malignant disease. In the older group (≥55 years), endometrial thickening (6.84), atypical genital bleeding (6.43) and BMI ≥25 kg/m2 (3.79) were found to be risk factors for malignancy. Of the patients with endometrial thickening and atypical genital bleeding, 67% were diagnosed with malignant disease. Among 63 samples diagnosed as ATEC, cannot exclude atypical endometrial hyperplasia or more, 35 (55.6%) samples were positive for malignancy. Conclusions: High‐risk patients diagnosed with ATEC, of undetermined significance were identified. Endometrial biopsy should be considered for nulligravida patients aged <55 years with a BMI ≥25 kg/m2. This study aims to develop a clinical management regimen for atypical endometrial cell (ATEC) categories within the descriptive reporting format for endometrial cytology, as no study, to date, has investigated the involvement of ATEC‐US (ATEC with undetermined significance) or ATEC‐A (ATEC, , cannot exclude atypical endometrial hyperplasia or more) in malignancy. We retrospectively reviewed the medical records of patients with ATEC to determine risk factors for the malignancy. This study suggests that an endometrial biopsy should be considered for patients with ATEC with more than two risk factors.
