Stage III is divided into IIIA and IIIB. Both show involvement of nodes in the center of the chest, but Stage IIIA tumors may be removed under certain circumstances.
Standard Treatment These tumors are treated mainly with radiation therapy , surgery or both, depending on the clinical circumstances.
Although most patients do not completely respond to radiation therapy alone, 5 to 10 percent do experience long-term survival benefit.
Radiation therapy is frequently given after surgery. Although there is no evidence that this improves survival, there can be a decrease in recurrences at the original tumor site.
