In Korea, the incidence of breast cancer is continuously increasing. Since 2001, breast cancer is the most common cancer in females.(1)


We analyzed the clinical data of 323 breast cancer patients who were treated in department of surgery at Pusan National University Hospital between January 2001 and December 2002.


A total of 323 patients, 322 patients are female and 1 patient is male. The most common prevalent age was the fifth decades. The most common sign and symptom was a painless palpable mass. The most common tumor location was the left upper outer quadrant. The main preoperative histologic diagnostic methods were core needle biopsy (48.3%) and Fine Needle Aspiration (35.6%). Breast conservation surgeries were performed in 259 cases (80.2%), a modified radical mastectomy in 35 cases (10.9%), a radical mastectomy in 3 cases (0.9%), a simple mastectomy in 3 cases (0.9%) and other procedures in 23 cases (7.1%). According to the TNM staging system, the most common stage was stage IIA (121 cases, 37.4%). The most common pathologic type was invasive ductal carcinoma (273 cases, 84.6%). Axillary lymph node metastasis was present in 109 cases (33.7%). The most common distant metastasis site was the bone (12 cases, 3.7%). The average follow-up period was 22.3 months. 19 cases (5.9%) were recurred between 15 to 28 months after surgery. Their mean disease- free interval was 21.2months. During the follow-up, 4 patients died.


In spite of the short follow-up period, this study shows that breast conservation surgery is a recommendable modality in breast cancer, in terms of recurrence rate, disease free survival, patient's satisfaction and cosmetics.
