Diagnostic value of ultrasonography with mammography image in breast cancer patients

Objective To evaluate the value of ultrasonography combined with mammography in diagnosis of breast cancer. Methods A total of 98 patients who were definitely diagnosed as breast cancer by pathological examination after surgery in the Second Affiliated Hospital of Suzhou University from January to November 2014 were chosen as study objects, and 112 masses were removed after surgery.All the patients underwent both ultrasonography and mammography examinations before operation, and the ultrasonogram features of both were summarized.The diagnostic accuracy of ultrasonography, mammography and the combination of these two methods were analysed according to results of pathological examination after surgery. Results ①The main manifestation of ultrasonography results of 112 masses were: the irregular shape of lump was 96% (107/112), obscure boundary of lump was 88%(99/112), the hypoecho of lump was 86%(96/112) and the uneven echo of lump was 85%(95/112). ②The main features of ultrasonogram of mammography in breast cancer were irregular shape, uneven internal echo and high density masses, and has obscure boundary with surrounding tissues.③There was no significant difference between ultrasonography and mammography in diagnostic accuracy of breast cancer (83.04% vs 78.57%, χ2=0.72, P=0.400). The diagnostic accuracy of breast cancer of ultrasonography combined with mammography (91.96%)was higher than that of ultrasonography or mammography alone, and the differences were significant(χ2=4.08, P=0.040; χ2=8.00, P=0.005). Conclusions Ultrasonography and mammography were both important iconography examinations of breast cancer diagnosis.Combination of these two examinations can improve the diagnostic accuracy of breast cancer, and provide guidance of preoperative and prognostic evaluation for clinicist.
