Objective To investigate the diagnostic value of oral contrast ultrasonography （ OCUS ） and acoustic radiation force Imaging （ ARFI ） in the pathological differentiation of advanced gastric cancer. Methods 56 cases of patients with gastric cancer which were confirmed by pathology in Tongde Hospital of Zhejiang Province from February 2015 to November 2017 were selected. According to the different pathological differentiation, patients were divided into： the differentiation group （26 cases ） and undifferentiated group （30 cases ） . 1 week before surgery, all patients had OCUS and AIkFI examination, and the maximum diameter and ARFI value of tumor were measured and recorded, and the results were compared with pathological results. Results The maximum diameter of undifferentiated group was significantly greater than that of differentiation group, and the difference was statistically significant （ P〈0.05 ） ; ARFI value of undifferentiated group was significantly higher than that of differentiation group, and the difference was statistically significant （ P〈0.05 ） ; l？,OC curve showed the AtkFI value determine the undifferentiated advanced gastric cancer, and the area under curve was 0.861; 95% confidence interval was 0.768～0.954; cut-off value was 4.27m/s; sensitivity was 72.00%, and specificity was 83.90%. Conclusion ARFI has the advantages of non-invasive, convenient and so on. It is helpful for the objective and accurate evaluation of the pathological differentiation of advanced gastric cancer, which has certain clinical value.
