Evaluation Of Digital Mammography Node Metastasis In Diagnosis Of Axillary Lymph In Breast Cancer

The purpose of this experiment is mainly to study the value of Digital mammography in diagnosis of Patho-typing and the situation of axillary lymph of breast cancer before operation .Through the analysis digital mammography of patients preoperatively , We can understand the whole pathogenetic condition and select the best treatment for patients. The research could be divided into two parts. The first part is to the valua of digital mammography in diagnose of patho-typing of breast cancer. The second part is to the valua of digital mammography node metastasis in diagnosis of axillary lymph in breast cancer .Parts I : the value of digital mammography in diagnose of patho-typing of breast cancer.Objective : To explore the value of digital mammography in the diagnosis of pathotyping of breast cancer.Material and Method: To collect digital mammography films from 260 breast cancers who were proved by postoperative pathology,including infiltrating ductal carcinoma (120),ductal cancinoma in situ (40),invasing lobular carcinoma (30),mucinous carcinoma (40),medullary carcinoma (30). Comprehensively analyse the characteristics of different breast cancer in digital mammography.Results: 1) The more frequent expression of X-ray In infiltrating ductal carcinoma is calcification and mass with invasive rim and asterism rim, calcification always company with mass 2) The extent of calcification in DCIS is less than In infiltrating ductal carcinoma ,and mostly distribute in linear .3)Masses were more commonly associated with medullary and mucinous carcinom,with sublobe or clear rim .4) Invasing lobular carcinoma is more of mass with invasive rim and asterism rim ,this is similar to infiltrating ductal carcinoma. But the probability of structure distortion in Invasing lobular carcinoma more than infiltrating ductal carcinoma .Conclusion: Compare to the traditional mammography, digital mammography not only elevate detection rate of breast cancer ,but also early diagnosis Patho-typing of breast cancer Preoperation, through all kinds of treatments after image.Parts 2: value of digital mammography node metastasis in diagnosis of axillary lymph in breast cancerObjective: To explore the value of digital mammography in judge the occurrence of axillary lymph node metastasis in breast cancer.Material and Method : To collect digital mammography films from 260 breast cancers were proved by postoperative pathology and 110 out-patients of hyperplasia of mammary glands. Comprehensively analyse the characteristics of axillary lymph node in mammography.Results: Axillary lymph node in mammography of hyperplasia of mammary glands with different number and size, clear boundary, the diversity of shape, homogeneous mass, much is similar of cycle and axillary tissue is distinct. Compare to the mammography of hyperplasia of mammary glands, the number and size of axillary lymph node is non-specificity in mammary of breast cancer, but much with homogeneous mass and shape of cycle and ellipse, obscure boundary, tissues around the lymph node is confused.Conclusion :Through the analysis and compare of the mass, boundary, shape of the axillary lymph node and the construction of tissues around the lymph node preoperatively, we can make a preliminary understanding of the state of axillary lymph node metastasis and benefit to the whole understanding breast cancer and the select of treatment.
