Abstract:
Objective To evaluate the values of different methods in breast cancer screening using receiver operating characteristic (ROC)curve analysis,and to suggest a appropriate model for female breast cancer screening in rural areas. Methods After questionnaire investigation and clinical examination,breast ultrasound and X -ray mammography were performed in the high risk group.Sensitivity and specificity of clinical examination, breast ultrasound, X -ray mammography and comprehensive examination were evaluated by ROC curves.Results There were 31 pathologically diagnosed cases among the 23,910 screening women.The detection rate of breast cancer was 129.65 /100,000.The sensitivity,specificity and the area under the ROC curves was 90.323,94.604 and 0.954 respectively for comprehensive examination,and 70.968,90.288 and 0.814 respectively for ultrasound examination,and 74.194,91.727 and 0.850 respectively for mammography examination,and 41.935,82.734 and 0.676 respectively for clinical examination.After Z test,comprehensive examination was better than other methods (P <0.05)and there was no significant difference between breast ultrasound and X -ray mammography (P >0.05).Conclusion Both ultrasound and X -ray mammography are the effective methods in breast cancer screening.The comprehensive examination could significantly improve the diagnostic capabilities of breast cancer.
