Abstract

Currently, the single most effective means to cure a woman of breast cancer is through the early diagnosis and appropriate treatment of the disease. Fine needle aspiration cytology(FNAC) can be used in most patients with palpable breast mass.
Mammography has enabled physicians to diagnose many nonpalpable or occult carcinomas of the breast that re often node negative and smaller than 1cm in diameter and allows for increased cure rate. Ultrasonography of the breast is difficult in the
diagnosis o carcinoma of the breast, but best suited for the differentiation of cystic from solid lesion found by palpation or on mammography.
56 patients with a palpable breast mass were diagnosed as breast carcinoma with excisional biopsy from June 1992 to May 1994 at the Department of Surgery, St. Columban's Hospital.
Among 56 patients, FNAC was done on 38 patients, these mammography on patients and ultrasonography on 35 patients. The results of these three diagnostic procedures were compared with the postexcisional histopathologic diagnosis.
@ES The results of this study were as follows;
@EN 1) The histopathologic diagnosis of 56 cases was ductal carcinoma in situ in 2 cases. in vasive ductal carcinoma in 49 cases, invasive lobular carcinoma in 4 cases and medullary carcinoma in 1 case.
2) Preoperatively, in the 38 FNAC Cases, the cytologic diagnosis was malignant in 18 cases, suspicious for malignant in 11 cases benign in 3 cases and inadequate in 5 cases (13.2%).
3) Preoperatively, 30 cases performed mammography. The mammographic diagnosis was malignant in 23 cases, suspicious for malignant in 3 cases and benign in 4 cases.
4) On mammogram, 2 cases(6.7%) showed only microcalcification, only mass in 17 cases (56.7%) and mass with microcalcification in 11 cases(366%). The margin of mass was ill-defined in 14 cases(46.7%), well-defined in 4 cases(13.3%), spiculated in
10
cases(33.3%) and 2 cases(6.7%) revealed no mass lesion.
5) On ultrasonogram of breast, 22 cases(62.9%) showed lobulated shape, irregular contour in 29 cases(82.9%), heterogenicity in 21 cases(91.4%), echolucent internal echo in 29 cases (82.8%), echogenic boundary echo in 21 cases(60.0%), posterior
wall
enhancement in 31 cases (88.6%) and posterior shadowing was not showed in any case.
6) Sensitivity rate for the malignancy of the breast in FNAC was 76.3%, that of the mammography was 86.7% and that of the ultrasonography of breast was 77.1%.
