@EN 1) The peak incidence was in the 40's (135 cases, 36.4%) and the average age was 47.
2) The most frequent histopathologic type ws infiltrating ductal carcinoma (288 cases, 77.8%).
3) The 5-year survival rate and 5-year disease free survival rate in 371 patients using the Kaplan-Meier Estimate were 83.9% and 74.8%, respectively.
4) According to the T.N.M. system, 14.5% belonged to stage 1,48.0% to stage II, 33.7% to stage III and 1.9% to stage IV. Five year survival rates for the patients in stage I, II, III were 97.6%, 94.0% and 74.8%, respectively.
5) Five year survival rates according to the tumor sizes smaller than 2cm, between 2 and 5cm, and large than 5m were 87.2%, 86.9% and 67.1%, respectively.
6) Five year survival rates according to the number of axillary lymph nodes involved were: 91.8% for those with no axillary metastasis, 90.1% for those with 1-3 positive lymph nodes, 65.3% for the those with 4-9 positive lymph nodes, and 53.4%
for
those with 10 more positive lymph nodes.
7) There was no significant difference in survival rates between the premenopausal and postmenopausal women.
