Volumetric change of the latissimus dorsi muscle after postoperative chemotherapy and radiotherapy in immediate breast reconstruction with an extended latissimus dorsi musculocutaneous flap: final results from serial studies

Background Breast reconstruction using an extended latissimus dorsi (eLD) flap can supplement more volume than reconstruction using various local flaps after partial mastectomy, and it is a valuable surgical method since the reconstruction area is not limited. However, when performing reconstruction...

However, when performing reconstruction, the surgeon should consider latissimus dorsi (LD) volume reduction due to postoperative chemotherapy (POCTx) and postoperative radiotherapy (PORTx). To evaluate the effect of POCTx and PORTx on LD volume reduction, the effects of each therapy—both separately and jointly—need to be demonstrated. The present study quantified LD volume reduction in patients who underwent POCTx and PORTx after receiving breast-conserving surgery (BCS) with an eLD flap. Methods This study included 48 patients who received immediate breast reconstruction using an eLD flap from January 2013 to March 2017, had chest computed tomography (CT) 7–10 days after surgery and 10–14 months after radiotherapy completion, and were observed for more than 3 years postoperatively. One surgeon performed the breast reconstruction procedures, and measurements of breast volume were obtained from axial CT views, using a picture archiving and communication system. A P-value <0.05 was the threshold for statistical significance. Results The average volume reduction of LD at 10–14 months after completing POCTx and PORTx was 64.5% (range, 42.8%–81.4%) in comparison to the volume measured 7–10 days after surgery. This change was statistically significant (P<0.05). Conclusions Based on the findings of this study, when harvesting an eLD flap, surgeons should anticipate an average LD volume reduction of 64.5% if chemotherapy and radiotherapy are scheduled after BCS with an eLD flap.Kyeong Ho SongWon Seok OhJae Woo LeeMin Wook KimDae Kyun JeongSeong Hwan BaeHyun Yul KimYoun Joo JungKi Seok ChooKyung Jin NamJi Hyeon JooMi Sook YunSu Bong NamKorean Society of Plastic and Reconstructive Surgeonsarticlemammaplastybreast reconstructionchemotherapyradiotherapySurgeryRD1-811ENArchives of Plastic Surgery, Vol 48, Iss 6, Pp 607-613 (2021)
