| Popis: | Objective To evaluate the accuracy, sensitivity, and specificity of DNA quantitative cytology test for the diagnosis of endometrial cancer or precancerous lesions and then discuss the value of DNA quantitative cytology as a screening tool for endometrial cancer. Methods The study enrolled 575 patients from September 2013 to January 2017 in Shanghai Minhang Central Hospital. Endometrial hysteroscopy plus dilation and curettage and DNA quantitative cytology tests were conducted as a method for the diagnosis of endometrial cancer. The accuracy, sensitivity, and specificity of this method were calculated according to histopathologic diagnoses which were used as the gold standard for diagnosis confirmation. Results For the DNA quantitative cytology diagnosis of endometrial cancer, accuracy was estimated at 85.57%, sensitivity at 87.01%, specificity at 85.34%, positive predictive value (PPV) at 47.86%, and negative predictive value (NPV) at 97.07%. For the DNA quantitative cytology diagnosis of endometrial cancer in menopausal patients: accuracy was estimated at 89.95%, sensitivity at 97.73%, specificity at 87.59%, positive predictive value (PPV) at 70.49%, negative predictive value (NPV) at 99.22%. For the DNA quantitative cytology diagnosis of endometrial cancer in non-menopausal patients, accuracy was estimated at 83.42%, sensitivity at 72.73%, specificity at 84.42%, positive predictive value (PPV) at 30.38%, and negative predictive value (NPV) at 97.07%. Conclusion DNA heteroploidy can be tested for the occurrence and the development of endometrial cancer. A small number of non-endometrial cancer cases may also appear DNA heteroploidy, but the number of >5c cells is less than 3. DNA quantitative analysis is a useful tool for the screening of endometrial cancer, worthy of being popularized and applied in endometrial cancer diagnosis. |
