We investigated the clinical characteristics of breast cancers and its significance. MATERIAL AND METHOD: We evaluated the clinical characteristics of 500 women with breast cancer who were diagnosed and treated by one surgeon between March 1991 and August 1996.
The median age was 46.7 years and the most common age group was 40's. The presenting symptoms for most patients were palpable mass (75.2%) followed by abnormal mammographic findings (8.4%), pain (6.3%) and nipple discharges (4.7%), and the duration of symptoms was less than 1 month in 41.4%. Fifty three percent of the 500 cases had T2 lesion (size; 2 to 5 cm). With the increase of tumor size, overall and disease free survival rates (OS, DFS) were decreased. Surgical treatment consisted of modified radical mastectomy (52.8%) and partial mastectomy (33.6%) The most common stage was II (42.3%) and the early breast cancer (stage 0, I, II) was 388cases (78.1%) and the stage were inversely correlated with DFS and OS. The positivity of axillary lymph node was 39.3% and the number of the metastatic lymph nodes was inversely correlated with DFS and OS. The pathologic types were infiltrating ductal carcinoma (83.0%), ductal carcinoma in situ (12.8%), infiltrating lobular carcinoma (1.2%), lobular carcinoma in situ (0.4%) and Paget's disease (2.0%). ER positivity was 48.9% and PR 46.9%. ER positive patients showed survival benefit compared to ER negative patients. The common sites of distant metastases were lung, bone and liver.
Our patients with breast cancer were younger than those of western and showed the impacts on survival according to the lymph node status,tumor size.
