Neoadjuvant Radiation Therapy ± Concurrent Chemotherapy

How Neoadjuvant Radiation Therapy ± Concurrent Chemotherapy is performed

Neoadjuvant radiotherapy is often performed with intensity-modulated radiation therapy (IMRT) or volumetric modulated arc therapy (VMAT); chemotherapy can be synchronized as needed. Typically, body position fixation and CT/MRI simulation are performed first, the doctor outlines the target area and organs at risk, and the physicist reverse optimizes the plan and performs quality control; during the treatment period, image-guided irradiation is performed sequentially. Blood counts, skin, and intestinal reactions are monitored concurrently, with the goal of downstaging, shrinking the tumor, and creating conditions for subsequent surgery or organ preservation. The above is general health information, not medical advice; specific details are subject to specialist assessment and hospital protocols.
