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
Memorial Sloan Kettering Cancer Center
Summary
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.

Inclusion Criteria: * Female sex, aged ≥18 years, with biopsy-proven invasive breast cancer * cT3-4 cN0-3 tumor * Partial or complete response to NAC on imaging and clinical examination using the Response Evaluation Criteria in Solid Tumors (RECISTv1.1) definition. * Desire to undergo autologous reconstruction and assessed to be an appropriate candidate by a plastic and reconstructive surgeon * Able to read and understand English Exclusion Criteria: * Prior ipsilateral breast cancer * Bilateral breast cancer * Pregnant * Stage IV disease at presentation * Stable disease or progressive disea…
Interventions
- Diagnostic TestPre-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
- RadiationNeoadjuvant radiotherapy
After biopsy, participants will undergo neoadjuvant radiotherapy/NART
- ProcedureUnilateral 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.
