유방암 환자의 생존율

Abstract

Three hundred and seventy one patients with breast cancer were retrospectively analysed to assess prognostic factors, in the period between 1985 and 1994. The results were as follows： 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 was 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 I, 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 2 cm, between 2 and 5 cm, and large than 5 cm 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.
