摘　　要：BACKGROUND Breast cancer morbidity has been increasing worldwide,but treatments are improving.The therapeutic response depends on the stage at which the disease is diagnosed.Therefore,early diagnosis has never been more essential for successful treatment and a reduction in mortality rates.Radiology plays a pivotal role in cancer detection,and advances in ultrasound(US)palpation have shown promising results for breast cancer imaging.The addition of two-dimensional-shear wave elastography(2D-SWE)US in the routine breast imaging exam can increase early cancer detection and promote better surveillance.AIM To evaluate the clinical applications of 2D-SWE US in breast cancer detection and its combination with other imaging modalities.METHODS The 200 consecutive female patients aged 50-80 were examined to evaluate palpable breast lesions.All patients underwent mammography,bright mode(B-mode)US,and 2D-SWE followed by US-guided biopsy in two consecutive sessions.RESULTS Combining B-mode and shear wave US imaging with X-ray mammography revealed 100%of the suspicious lesions,resulting in greater sensitivity,specificity,and negative predictive value.The result improves compared to either B-mode or 2D-SWE alone(P=0.02).CONCLUSION Combining 2D-SWE with conventional US and X-ray techniques improves the chance of early cancer detection.Including 2D-SWE in regular breast imaging routines can reduce the need for biopsies and improve the chance of early cancer detection and survivability with the proper line of therapy.
