Breast conserving operation for breast cancer with 2 cm and 3 cm incision margins: A comparison of outcomes / 第二军医大学学报

ABSTRACT

Objective: To explore the relationship between margin width in extended lumpectomy for breast cancer with survival rate, local recurrence rate, and cosmetic result. Methods: The clinical data of 42 breast cancer patients who had a 2cm incision margin width (group A) and 37 who had a 3cm incision margin width (group B) were retrospectively analyzed. The 5-year, 10-year survival rates, recurrence rates, and the cosmetic results were compared between the 2 groups. Results: The 5-year and 10-year survival rates in patients of group A were 90.1% and 85.3%, respectively; in patients of group B were 92.3% and 83.6% , respectively(P>0.05). The 5-year and 10-year local recurrence rates in patients of group A were 5.9%, and 11.%, respectively; in patients of group B were 3.4% and 12.9%, respectively(P>0.05). The cosmetic result was significantly better in group A than that in group B(P<0.05). Conclusion: An incision margin width of 2 cm is enough for extended lumpectomy. It is not necessary to further expand the margin width; otherwise, it may influence the cosmetic results after operation.
