The clinical observation was performed on 202 cases of female mammary carcinoma from Septmber,
1955 to December, 1970 at Surgical Department of Yonsei Medical Center. Analysiss of the experiences
including late result provided following results.
1) The percentage ratio of breast cancer to the total number of admitted patients during the aforemen
tioned period was 0.19%.
2) The peak incidence was in the age group of 40 to 49 and its number of patients was 86 (42.3%)
The extreme of age was represented by age of 25 and 78.
3) The most prominent symptom was palpable mass in 201 cases and it was followed by skin retrac
tion in 56 cases, pain in 37 cases, nipple discharges in 31 cases, and so on. In 146 cases(70%), visit
was done within one year.
4) The lefe side breast was more affected than the right side breast, represent by 108 cases in the left
and 96 cases in the right. The most frequent site of the breast cancer was the upper-outer quadrant in
96 cases (46.1%), and followed by the upper-inner quadrant in 35 cases (16.7%), and the center and
lower-outer quadrant in 20 cases (12.3%) each. There was 2 cases (1%) of simultaneous bilateral
carcinoma.
5) The Manchester´s and/or Portman´s classification were employed for staging. The most frequent
stage was StageⅠ, 42.6% and it was following by Stage Ⅱ, 37,6%.
6) The classic and/or modified Halsted radical mastectomy was a choice of Surgical procedure for
early carcinoma of the breast. Surgery was performed in 191 patients. Among 191 cases, 141 patient
underwent redical mastectomy. More radical method, extended radicalmastectomy by Urban´s technique
was employed in cases and more conservative method, simple mastectomy with or without irradiation
and 32 patients underwent oophorectomy. Simple mastectomy performed in stageⅠ and Ⅱ cancer was
exceptional for patients with old age or with associated disease, therefore, it was usually done for pallia
tive purpose.
7) There were 3 hospital death; 2 with deseminated terminal cancer and another due to bleeding after
simple mastectomy. None have as yet died from radical surgery.
8) In redical mastectomy group, follow up was successful in 66% of patients between 1955 and 1965,
while 59% of patients between 1960 and 1970 was able to contact. Average 5 year survival rate was
75.2% in node negative group (stageⅠ) and 42.2% in node positive group (stageⅡ). Therfore overall
5 year survival rate was obtained in 57%, however, 5 year clinical cure rate was low, recording 29%.
