Thus, this study was conducted to evaluate <jats:italic>\u03b2<\/jats:italic>-HCG regression after evacuation as a predictive factor of malignant GTN in complete molar pregnancy. <jats:italic>Methods<\/jats:italic>. In this cross-sectional study, we evaluated a total of 260 patients with complete molar pregnancy. Sixteen of the 260 patients were excluded. Serum levels of HCG were measured in all patients before treatment and after evacuation. HCG level was measured weekly until it reached a level lower than 5\u2009mIU\/mL. <jats:italic>Results<\/jats:italic>. The only predictors of persistent GTN are HCG levels one and two weeks after evacuation. The cut-off point for the preevacuation HCG level was 6000\u2009mIU\/mL (area under the curve, AUC, 0.58; sensitivity, 38.53%; specificity, 77.4%), whereas cut-off points for HCG levels one and two weeks after evacuation were 6288\u2009mIU\/mL (AUC, 0.63; sensitivity, 50.46%; specificity, 77.0%) and 801\u2009mIU\/mL (AUC, 0.80; sensitivity, 79.82%; specificity, 71.64%), respectively. <jats:italic>Conclusion<\/jats:italic>. The rate of decrease of HCG level at two weeks after surgical evacuation is the most reliable and strongest predictive factor for the progression of molar pregnancies to persistent GTN.<\/jats:p>","DOI":"10.1155\/2014\/494695","type":"journal-article","created":{"date-parts":[[2014,3,25]],"date-time":"2014-03-25T04:01:25Z","timestamp":1395720085000},"page":"1-4","source":"Crossref","is-referenced-by-count":9,"title":["Does
