Analysis Of Breast Cancer Patients With Axillary LNM Of The Relevant Factors And The Performance Of Contrast-enhanced Ultrasound

Objective: To observe the primary tumor in patients with breast cancer and axillary LN two-dimensional signs and blood supply, while some of the axillary LN to ultrasound contrast studies, analysis of breast cancer axillary LNM of the relevant factors, In order to arrive at the better diagnosis of breast cancer patients with axillary LNM.Methods: 66 cases of breast cancer patients, a detailed record of the patient's age, sex, breast primary tumor site, size, L/T value, the border, the internal calcified lesions, rear echo, primary tumor blood flow richness (0-â…¢level), blood flow velocity and resistance index. And then carefully to detect ipsilateral axillary LN, a detailed record of the lymph node diameter, L/T value, the diameter of local cortical thickness and the type of blood flow distribution, analysis of the primary tumor and axillary LN of the indicators and the relationship between LNM. At the same time, of which 10 cases of axillary LN contrast-enhanced ultrasound to observe the enhancement methods and intensity after contrast and analysis of the time intensity curve to identify with the relationship between the axillary LNM.Results: The patient's age, primary tumor blood flow velocity, the primary tumor site, primary L/T, position, borders, rear echo and internal calcification is not related to axillary lymph node metastasis (P> 0.05). Maximal diameter of the primary tumor, primary tumor blood flow richness, the largest lymph node diameter, the thickest local cortex diameter, lymph node L/T value and the type of lymph node blood flow distribution is related to axillary lymph node metastasis (P <0.05), The degree of correlation between the relevant indicators and axillary lymph node metastases as follows: lymph node diameter of local cortical thickness> the type of lymph flow distribution> the primary tumor blood flow richness> the largest lymph node diameter> primary tumor diameter> lymph node L/T. Contrast the performance of axillary LNM started from the periphery markedly enhanced, which shows that small-scale non-perfusion or uneven distribution of contrast agent, and the time intensity curve showed a faster rise, there is a turning point decline.Conclusion: The identification of breast cancer patients for benign and malignant axillary LN should be considered the primary tumor size, primary tumor blood flow richness, LN diameter, the local cortical thickness, L/T value, the distribution of blood types, combined with the performance of LN Contrast-enhanced ultrasound, will help to improve ultrasound diagnostic accuracy rate of LNM and more accurate to determine the status of axillary LN.
