Abstract Objective: To study a relationship between ultrasonic elastography(UE) score and pathological characteristic of breast cancer and its value for evaluating lymphatic metastasis of breast cancer. Method: A total of 148 breast cancer patients treated in our hospital from May 2019 to May 2021 were taken for routine ultrasound with UE, and pathological findings were taken as the golden standards. The relationship between the UE score and histopathological characteristic of the breast cancer patients was analyzed, and the diagnostic value of two diagnostic methods on lymphatic metastasis of breast cancer were compared. Results: Among 148 cases of breast cancer, 8 cases were medullary carcinoma, 6 cases were invasive lobular carcinoma and 134 cases were invasive ductal carcinoma. 82 cases (55.41%) had metastatic axillary lymph nodes, and 66 cases (44.59%) had non-metastatic axillary lymph nodes. Correlation analysis showed that UE score had no correlation with tumor size (P>0.05). UE score was significantly correlated with tumor type, tumor grade and lymph node metastasis (P<0.05). The blood flow of metastatic axillary lymph nodes was mainly type III, accounting for 52.43%. Non-metastatic axillary lymph node blood flow was mainly type I, accounting for 53.03% (P<0.05). UE score of metastatic axillary lymph nodes was 3 or above, accounting for 82.93%. UE score of non-metastatic axillary lymph nodes was 2 or below, accounting for 77.27% (P<0.05). The average UE score of metastatic axillary lymph nodes was higher than that of non-metastatic lymph nodes (P<0.05). Among 148 breast cancer patients, UE showed metastatic axillary lymph nodes in 71 cases, which was consistent with pathology in 69 cases. Conventional ultrasound showed metastatic axillary lymph nodes in 69 cases, which was consistent with pathology in 66 cases. The sensitivity (84.15%), specificity (93.94%) and accuracy (88.51%) of UE diagnostic method were higher than those of conventional ultrasound group. Conclusion: UE score has a certain relationship with histopathology of breast cancer patients, and UE has higher diagnostic value for lymphatic metastasis of breast cancer than conventional ultrasound, there was no statistical significance between them (P>0.05).
