The difference of the depth of myometrial invasion in endometrial carcinoma with intraoperative visual observation between the superior and junior doctors

Objective To improve the accuracy of the depth of myometrial invasion of endometrial cancer observed by naked eyes during operation through investigating the difference of the depth of myometrial invasion in endometrial carcinoma with intraoperative visual observation between superior and junior doctors.Methods The data from endometrial cancer in-patients with stageⅠ of surgical-pathological staging was collected and compared in Fuyang tumor hospital from Jan.2000 to Oct.2009.The results of the depth of myometrial invasion in endometrial carcinoma with intraoperative visual observation between the superior and junior doctors were compared and in according to the gold standard as postoperative pathological diagnosis.Results The diagnostic accuracy rate of myometrial invasion overall was 58.54% (24/41) and the diagnostic accuracy rate of deep myometrial invasion,shallow muscularis invasion was 69.23% (9/13) and 56% (14/25) respectively by the junior doctors.While The diagnostic accuracy rate of myometrial invasion overall was 90.24% (37/41)and the diagnostic accuracy rate of deep myometrial invasion,shallow muscularis invasion was 92.3% (12/13),and 88% (22/25)respectively by the junior doctors.The positive and negative predictive value of superior doctors used as intraoperative guidance was better than that of junior doctors through comparing the results of myometrial invasion in endometrial cancer determined by superior doctors and junior doctors.Conclusion Junior doctors could continue to improve the accuracy of the depth of myometrial invasion in endometrial carcinoma by visual observation through repeated comparisons to master the correct incision methods,observation methods and morphological diagnostic criteria,to accumulate pathological of experience.
