Brief summary
This study is the first prospective randomized study assessing the patient-reported outcomes and safety outcomes between preoperative and postmastectomy radiotherapy in locally advanced breast cancer patients with immediate reconstruction of deep inferior epigastric perforator(DIEP) flap. Radiotherapy before mastectomy and autologous free-flap breast reconstruction can avoid adverse radiation effects on healthy donor tissues and delays to adjuvant radiotherapy. We aimed to explore the feasibility of preoperative radiotherapy followed by DIEP flap reconstruction in patients with breast cancer requiring mastectomy.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patient satisfaction with breasts questionnaire Patient satisfaction of breast | 24 months after surgery | Patient satisfaction with breasts (as measured using the BREAST-Q reconstruction module) 24 months after surgery. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Complications of radiotherapy | 3 months, 12 months, and 24 months after radiotherapy | Complications of radiotherapy |
| Failure rate of breast reconstruction surgery | 8 weeks after surgery | Failure rate of breast reconstruction surgery |
| Patient satisfaction with outcome questionnaire | 3months, 12 months, and 24 months after surgery | Patient satisfaction with outcome (as measured using the BREAST-Q reconstruction module) 3months, 12 months, and 24 months after surgery |
| Complications of surgery | 3 months, 12 months, and 24 months | Complications of surgery |
| Total pathologic complete response (tpCR) | up to 4 weeks after surgery | pathologic complete response of breast and lymph nodes |
| 3-year disease free survival (DFS) | 3 years after diagnosis | Oncological safety |
| Aesthetic evaluation | 12 months and 24 months after surgery | Aesthetic evaluation (as measured using the Harris Score) 12 months and 24months after surgery. Breast aesthetic evaluation will subjectively be evaluated by two experts who applied the Harris score giving a mark of 1-4 for a poor to excellent result. |
