Evaluation on Diagnosis Significance of Single High Frequency Ultrasonography and Mammography and Combination on Breast Cancer
Abstract
Objective: To evaluate the diagnosis significance of single high-frequency ultrasonography and mammography and combination therapy of both on breast cancer.
Method: 352 cases of female breast cancer patients were selected in The First Affiliated Hospital of Zhengzhou University from January 2012 to December 2014. Among the 352 patients, 124 patients had only performed high-frequency ultrasonography detection, 102 cases of patients only conducted mammography, and 126 patients had applied the combination detection of high-frequency ultrasonography and mammography.
Results: The coincidence rate of single mammography detection was 79.4%, the misdiagnosis rate was 10.8%, and the missed diagnosis rate was 9.8%; the coincidence rate of single high-frequency ultrasonography detection was 83.9%, the misdiagnosis rate was 11.5%, the missed diagnosis rate was 4.6%; the coincidence rate of combination of high-frequency ultrasonography detection was 89.7%, the misdiagnosis rate was 6.3%, the missed diagnosis rate was 4.0%. The detection rate and missed diagnosis rate of combination diagnosis had a statistical difference with single high-frequency ultrasonography and single mammography. There was no statistical difference on misdiagnosis rate.
Conclusion: Mammography and high-frequency ultrasonography had their own advantages. The combination application of both had better diagnosis complementary, and could significantly improve the detection rate and accuracy rate on breast cancer, and decrease the misdiagnosis rate and missed diagnosis rate.
