The Effects of Radiotherapy on the Sequence and Eligibility of Breast Reconstruction: Current Evidence and Controversy.

Simple Summary: Breast reconstruction is considered for any patient who is undergoing surgical treatment for breast cancer. Many factors must be considered when discussing reconstruction, including patient risk factors, the type of material used for breast restoration, and the timing of surgery relative to other adjuvant treatments, such as radiotherapy. Plans for post-mastectomy radiotherapy significantly impact whether a breast reconstruction may be performed at the same time as a mastectomy (immediate reconstruction) or delayed for a later time (delayed reconstruction). The risk of surgical complications from irradiating a reconstructed breast is often weighed against the benefits of fewer surgeries and the potential for an improved quality of life when discussing eligibility for immediate reconstruction. This narrative review covers the current trends and controversies regarding breast reconstruction and radiotherapy. We aim to provide the context and relevant evidence for general community-practice oncologists and oncology providers who counsel patients on the sequencing and modalities of radiotherapy and breast reconstruction. Immediate breast reconstruction (IBR) following a mastectomy, combined with radiotherapy, presents a multifaceted approach to breast cancer treatment, balancing oncological safety and aesthetic outcomes. IBR, typically involving the use of implants or autologous tissue, aims to restore breast morphology directly after a mastectomy, minimizing the psychological and physical impacts. However, integrating radiotherapy with IBR is complex due to the potential adverse effects on reconstructed tissues. Radiotherapy, essential for reducing local recurrence, can induce fibrosis, capsular contracture, and compromised aesthetic results. This narrative review covers the current trends in the sequencing of breast reconstruction and radiotherapy. We discuss patient selection, timing of radiotherapy, and reconstructive techniques, with special attention paid to quality-of-life outcomes that are increasingly reported in clinical trials. Emerging evidence supports the feasibility of IBR with careful patient selection and tailored therapeutic approaches, although ongoing research is necessary to refine protocols and enhance outcomes. Overall, IBR in the context of radiotherapy remains a promising but intricate treatment modality, requiring a nuanced balance between cancer control and aesthetic restoration. [ABSTRACT FROM AUTHOR]
