Dr. Jeffrey Bradley, Radiation Oncologist at Washington University in St. Louis, defines the V20 standard for lung radiation and outlines the advantages of limiting dose and field size in lung radiation therapy.

The Radiation Therapy Oncology Group (RTOG) has been working on a large randomized trial in patients with stage III, locally advanced, unresectable NSCLC that asked two key questions:
1) is the best dose of radiation the "old" standard of 60 Gray (Gy), over about 6 weeks, or a higher dose of 74 Gy that has been found to be feasible?
2) Is there a value in adding weekly Erbitux (cetuximab), the antibody to the epidermal growth factor receptor (EGFR), along with weekly carboplatin/Taxol (paclitaxel) and concurrent chest radiation therapy (RT)?
