A useful scoring system combining weighted risk factors derived from a regression model is as follows: (2 \u00d7 age \u226550 years) + (3 \u00d7 BMI \u226530) + (2 \u00d7 menopausal status) + (2 \u00d7 diabetes comorbidity) + (3 \u00d7 endometrial thickness &gt;12 mm). The AUC of this score was 0.793, and the score afforded 80.9% sensitivity, 70.3% specificity, a 75.3% positive predictive value, and a 76.4% negative predictive value, when a score of 5 was used as a cutoff. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Patients with ACH should be evaluated by gynecological oncologists and intraoperative frozen section analysis should be performed by pathologists specializing in the evaluation of gynecological malignancies, because ACH is closely associated with endometrial cancer (EC). Our novel preoperative scoring system may aid in the detection of patients at increased risk of EC and thus guide general gynecologists.<\/jats:p>","DOI":"10.1159\/000365086","type":"journal-article","created":{"date-parts":[[2014,9,18]],"date-time":"2014-09-18T13:51:40Z","timestamp":1411048300000},"page":"50-56","source":"Crossref","is-referenced-by-count":11,"title":["A
