Официальное название
Feasibility of Preoperative Radiotherapy in T3 and T4 Breast Cancer Patients Who Are Responders to Neoadjuvant Chemotherapy to Allow for Immediate Reconstruction: a Prospective Study
Обзор
The purpose of this study to test an alternative treatment approach that involves giving participants radiotherapy before their mastectomy (preoperative radiotherapy) and performing immediate reconstruction surgery at the time of mastectomy. The immediate reconstruction surgery is called an immediate autologous reconstruction (IR) and is different than the standard reconstruction surgery people with T4 breast cancer have. IR is a surgical procedure where immediately following your mastectomy, the surgeon takes tissue from another part of your body and uses it to re-create your breast. The standard reconstruction surgery occurs later and can be done with an implant or tissue from your body. The main purpose of this study to find out if the alternative treatment approach shown above is feasible. The study will see how safe this alternative treatment approach is compared with the standard treatment approach.
Вмешательства
- Диагностический тест Pre-neoadjuvant radiotherapy (NART) biopsy
Participants will undergo pre-NART core biopsy guided by post-NAC MRI to the area of residual enhancement or to the previously biopsied cancer if no residual enhancement remains - Лучевая терапия Neoadjuvant radiotherapy
After biopsy, participants will undergo neoadjuvant radiotherapy/NART - Процедура Unilateral total mastectomy with axillary lymph node dissection
At 2-6 weeks after completion of NART, participants will undergo unilateral MRM (total mastectomy with axillary lymph node dissection), with resection of all involved breast skin. Skin-sparing mastectomy will not be permitted. All patients will also undergo simultaneous unilateral autologous-based breast reconstruction with DIEP, ms-TRAM, or latissimus dorsi flap.
