DIEP Flap Breast Reconstruction: Perioperative Biomarkers and Outcomes

Brief Summary This observational study will follow patients who undergo DIEP flap breast reconstruction to better understand a common surgical challenge called ischemia-reperfusion (I/R) injury. I/R injury can happen when a flap has a period without blood flow (ischemia) and then blood flow returns (reperfusion). This process may trigger inflammation and oxidative stress and is associated with fat necrosis or partial flap loss. 1\. What is being studied 1. The investigators will measure inflammation and oxidative stress markers in blood (for example, interleukin-6 \[IL-6\]) from before surgery through the first 72 hours after surgery. 2. These data will help map the normal and abnormal patterns of recovery after surgery and may inform future approaches to monitoring and protecting flap tissue. 3. No experimental drug or device is given to participants in this study. Separate animal studies are developing a near-infrared imaging and antioxidant nanomaterial (Mn/QD-SAC); this is not used in participants here. 2\. Who can take part 1. Women aged 18-70 scheduled for immediate DIEP flap breast reconstruction after breast cancer surgery. 2. Key exclusions include severe heart, liver, or kidney disease; significant clotting problems; active infection or autoimmune disease; long-term use of immunosuppressants/anti-inflammatory drugs; pregnancy or breastfeeding; or other reasons judged by the research team. 3\. What will happen if you join 1. After providing informed consent, pa…
