<qa>  What is the name of the drug used in chemotherapy?RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs such as efaproxiral may make the tumor cells more sensitive to radiation therapy. It is not yet known if chemotherapy combined with radiation therapy is more effective with or without efaproxiral in treating non-small cell lung cancer.
