The Role of Breast Conserving Procedures in Breast Cancer Surgery

Abstract

Objective: Breast cancer treatment, especially surgery, has significantly changed in the last 30-40years. In this study, we aimed to discuss all the possible options ranging from radical mastectomyto breast-conserving surgery (BCS), and to utilize the conclusion in our daily practice.Methods: The study was retrospectively performed, and hospital records were used for quantitative data. The cases were classified into three groups. The cases having breast surgery in 1997 wereincluded in Group A; in 2007, Group B; and in 2017, Group C. Surgical methods, BCS and mastectomy, in these cases were compared with rates according to groups and cancer stage.Results: There were 515 cases in Group A, 519 in Group B, and 538 in Group C; and BCS wasperformed in 141, 238, and 372 cases, respectively (30%, 42%, 60.2%). Between Group A and C,a significant increase in the number of BCSs was observed. In the groups A, B, and C, BCS ratiosaccording to stage (S) were as follows: S I: 57%, 73%, and 86%; S II: 49%, 75%, and 82%; and S III:14%, 20%, and 48%. Subgroup analysis showed no BCS in S IV tumors in groups A and B. In Group,18 patients (25%) who received neoadjuvant chemotherapy were performed with BCS.Conclusion: Breast-conserving therapy is the standard approach in early-stage breast cancer. Compared to 20 years ago, the total number of patients undergoing BCS has increased >100%. Usuallywhen the tumor is diagnosed, we make the treatment plan for breast cancer in the multidisciplinarytumor board. This increases the feasibility of BCS in all stages.
