Objective:In order to deeper understand DCIS, improve the rate of diagnosis and therapeutic efficacy.
Methods :The clinical data of 123 DCIS treated at the First Affiliated Hospital of China Medical University were retrospectively analyzed in regards to age at onset of disease, clinical features, breast ultrasound examination, mammography examination, pathology, immunohistochemistry examination,and surgical methods.
Results:(1) The average age at onset was (47.7±9.3) years. (2)The major features on physical examination were breast lump in 79cases, nipple discharge in 19cases, and breast pain with glandular thickening in 30 cases. (3)Among 45 cases that underwent both ultrasound and mammography examination, in 17cases (60%) and 30 cases (66.7%) respectively,might be positive for malignancy, but the difference between the 2 melhods was not significant. With the use of both methods togather, diagmosis of possible malignant lesion was made in 37 cases (82.2%). (4) Sixty-five cases underwent breast ultrasound examination, substantive mass was found in 43 cases (66%), blood flow signals in 41 cases (63%),ductal dilatation in 52 cases (80%) and intraductal spotty strong light beam in 33 cases (50.7%).(5) Fifty-two cases underwent breast mammography examination, which showed sand-like calcification, mass with calcification clusters,localized gland density and breast tumor. (6)The immunohistochemistry examination included estrogen receptor (ER), progesterone receptor(PR), p53 and c-erbB-2,but the rate of positive expressios of those indices showed no significance difference between DCIS and DIS with microvasion (DCIS-MI).(7)Six cases underwent radical mastectomy (of which there were 3 cases of DCIS-MI). Modified radical mastectomy was done in 86 cases, including 59 cases of DCIS, 27 cases of DCIS-MI. Lymph node metastasis was found in 2 cases of DCIS,and 5 cases of DCIS-MI.
Conclusions:Combined breast ultrasound and mammography can increase the rate of DCIS diagnosis.
