Short Stay Management of Locally Advanced Breast Cancer Using Immediate Local Thoracoabdominal Advancement Flap and Enhanced Recovery After Surgery Protocol

Abstract

Background Patients with locally advanced invasive breast cancer (LABC) are often considered inoperable, because of the anticipated chest wall defect and need for complex reconstruction. We present a series of patients who underwent mastectomy with extensive skin resection and immediate chest wall reconstruction using a local thoracoabdominal advancement flap (TAAF). All patients were managed after surgery with an ERAS (Enhanced Recovery After Surgery) protocol, to decrease length of stay in hospital. We also present 1 patient who subsequently had satisfactory bilateral delayed breast reconstruction with pedicled latissimus dorsi myocutaneous flaps with prepectoral silicone implants. Methods This is a single-surgeon, single-institution retrospective chart review of patients with LABC who underwent mastectomy with skin resection and local TAAF from May 2017 to October 2019, with minimum 3-month follow-up. Results Thirteen patients met inclusion criteria. Twelve of 13 patients presented with stage III or IV invasive breast cancer, with skin involvement. The mean chest wall defect measured 248.7 cm2 (140–336 cm2; SD, 63.2 cm2), and all were successfully reconstructed with immediate local TAAF. There were no intraoperative complications, but 1 patient developed a postop hematoma. The mean hospital stay was 1.3 nights, with 9 patients (69.2%) staying less than 23 hours and 4 patients (30.8%) staying 2 nights. Nine patients (69.2%) underwent adjuvant therapy, beginning on average 32 days (13–55 days; SD, 13.1 days) after surgery. The mean follow-up time was 13.8 months (4.5–31.6 months; SD, 9.2 months). One patient underwent successful delayed bilateral breast reconstruction with pedicled latissimus dorsi myocutaneous flaps and silicone implant placement. Conclusions Our study demonstrates that reconstruction with local TAAF is an outpatient procedure that reliably provides durable, immediate chest wall coverage, after mastectomy in patients with LABC. This technique has a short operative time, low blood loss, and low complication rate, allowing timely adjuvant therapy. Using an ERAS postop protocol we were able to reduce mean hospital stay to 1.3 days. Compared with other described techniques of reconstruction, the additional scars and donor site morbidity are minimal, allowing for delayed breast reconstruction. We also present survival outcomes data on these surgically managed patients.
