Application of galactography in the diagnosis of breast cancer with nipple discharge

Objective:To study the galactography features of various pathology subtypes of breast carcinoma with nipple discharge,in order to improve the diagnosis accuracy.Methods:The mammography and galactography materials of 108 patients with surgery and pathology proved breast cancer were collected,including patients with bloody discharge(62 cases) and serous discharge(46 cases).The galactography features of different pathology subtypes of breast carcinoma(including infiltrative ductal carcinoma(64 cases,50%);infiltrative lobular carcinoma(23 cases,21.3%);miscelleneous 21 cases(medullary carcinoma,7 cases;ductal carcinoma in situ,7 cases;infiltrative papillary carcinoma,7 cases;lipotrophic carcinoma,2 cases;metaplastic carcinoma and mucinous carcinoma for 1 case each) were retrospectively analyzed.Results:Main galactography features were rat-tail sign(13 cases),rigidity of galactoducts(16 cases);filling defect(7 cases);ductal ectasia(99 cases);cut-off sign(24 cases);disorder of ductal structure(60 cases);ductal interruption(37 cases);wormy erosion of ducts(30 cases) and pond lake sign(32 cases).Of the 108 patients,106 patients showed two or more above-mentioned abnormalities.Conclusion:Fully understanding of the galactography findings of breast carcinoma with nipple discharge provides significant value in the diagnosis of breast cancer.The more the abnormal findings displayed the higher the diagnostic accuracy.
