Predicting toxicity from radiotherapy after breast cancer surgery and reconstruction

Prospective Evaluation of a Predictive Toxicity Test Post Radiotherapy After Mastectomy With Immediate Implant Reconstruction

Not applicable Interventional Institut du Cancer de Montpellier - Val d'Aurelle · NCT04342546

This study is testing a new test to see if it can help identify breast cancer patients who might experience severe side effects from radiation after surgery and reconstruction, so they can receive better care.

What this trial studies

This study evaluates the NovaGray RILA Breast® test's ability to predict the toxicity associated with radiotherapy following mastectomy and immediate breast implant reconstruction. It aims to identify patients at high risk for severe side effects from radiotherapy, which can negatively impact cosmetic outcomes and quality of life. By assessing T-CD8 lymphocyte apoptosis, the study seeks to personalize treatment strategies and potentially reduce unnecessary surgeries for low-risk patients. The goal is to improve patient care and outcomes in breast cancer treatment.

Who should consider this trial

Good fit: Ideal candidates include women aged 18 and older with histologically confirmed breast cancer who are undergoing mastectomy and are eligible for immediate breast reconstruction with implants.

Not a fit: Patients with inflammatory breast cancer, metastatic disease, or those requiring flap reconstruction will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment plans that minimize the risk of severe side effects from radiotherapy in breast cancer patients.

How similar studies have performed: Other studies have shown promise in using predictive tests for radiotherapy toxicity, but this specific approach with the NovaGray RILA Breast® test is relatively novel.
