Purpose : The study was to evaluate the various risk factors related to local
recurrence and distant metastasis in early breast cancer treated by lumpectomy with
axillary dissection.
Materials and Methods : Forty nine patients with early breast cancer were treated by
lumpectomy with axillary dissection between January, 1990 and December, 1996. We
analysed the risk factors such as age, tumor size, axillary lymph node metastasis, stage,
pathologic classification and radiotherapy for local recurrence and distant metastasis
Results : The peak incidence was in the fifth decade (15 cases, 31%) and the average
age was 47. The most common tumor size was 0¡­2 cm in 27 of 49 cases(55%). The
preoperative chemotherapy was performed in 25 of 49 cases. The axillary lymph node
metastasis was absent in 41 of 49 cases(84%). The most common pathologic type was
invasive ductal carcinoma (29 cases, 60%). The breast skin incision was performed with
curvilinear incision in 40 cases(85%), radial incision in 7 cases(15%). The axillary skin
incision was performed with seperated incision in 45 cases(96%), nonseperated incision
in 2 cases(4%). The most common complication was wound seroma (6 cases, 12%). By
the time of follow-up, crude local recurrence rate was 10% (5 out of 49 cases) and
crude distant metastasis rate was 6%(3 out of 49 cases).
Conclusion : The factors such as age, tumor size, positive axillary nodes and stage
were not statistically significantly related to local recurrence. Postoperative radiation
therapy and preoperative chemotherapy were the significant factor related to local
recurrence (2.6% for 39 cases with radiation therapy vs.40.0% for 10 cases without
radiation therapy, P<0.05; 0% for 25 cases with preoperative chemotherapy vs. 20.8% for
24 cases without preoperative chemotherapy, P<0.05).
