Abstract P3-18-14: Assessment of quality of life and objective cosmetic outcome of breast conserving surgery with or without latissimus dorsi mini-flap in breast cancer


 Introduction : Latissimus dorsi mini-flap (LDMF) with breast conserving surgery (BCS) was introduced as a useful volume replacement technique when the tumor is located in upper or outer portion of breast and the tumor size is large requiring extensive excision of breast tissue. However few studies have assessed quality of life (QoL) and objective cosmetic outcome of LDMF in breast cancer surgery. We tried to evaluate those in patients who underwent BCS with or without LDMF. Methods : This study was a prospective, single-center cohort study of patients who underwent LDMF and BCS between 2011 and 2018. As a control, patients who underwent BCS without any volume replacement and the tumor size equal to or greater than 2.5cm on the upper or upper outer of the breast on preoperative imaging. Breast Q questionnaire and body photo were taken at least 1 year after surgery. Two breast surgeons and one plastic surgeon who did not performed LDMF assessed the cosmetic outcome of the patients with photo. Results : 62 patients were in the BCS with LDMF group and 58 patients were in BCS-only group. Pathologic tumor size was significantly larger in LDMF group than BCS-only group (LDMF 3.89cm vs BCS-only 2.92cm, p= 0.001 ). Psychosocial well-being (P= 0.024), physical well-being (P= 0.000), and satisfaction with surgeon (p= 0.006) were significantly better in the BCS-only group than in the LDMF group respectively. But, there were no significant difference in neither sexual well-being (p= 0.286) nor satisfaction for breast (p=0.278) between BCS and LDMF group. In the physicians assessment, there was no significant difference in the cosmetic outcome score between the two groups (LDMF 2.56/4 vs. BCS-only 2.58/4, p= 0.884). Conclusion : In conclusion, physician assessed cosmetic outcome of LDMF was equivalent to that of BCS without LDMF although the tumor size was significantly larger in patients with LDMF. Some inferiority of QoL might be due to postoperative pain or arm movement discomfort. We are planning to evaluate objective cosmetic results using BCCT.core software.
