ASTRO: Radiation Beneficial After Lung Surgery, Chemo
In some lung cancer patients, radiation after surgery may double the average survival time
WEDNESDAY, Nov. 8 (HealthDay News) -- In lung cancer patients whose cancer has spread to the mediastinal lymph nodes, survival is twice as long in those who receive radiation after surgery and chemotherapy than in those who do not, according to research presented this week at the annual meeting of the American Society for Therapeutic Radiology and Oncology in Philadelphia.
Jean-Yves Douillard, M.D., Ph.D., of the Centre Rene Gauducheau in St. Herblain, France, and colleagues studied 840 non-small cell lung cancer patients, 232 of whom received radiation after undergoing surgery with or without chemotherapy.
The researchers found that patients who had radiation after surgery and chemotherapy lived almost two years longer (47 months versus 24 months) than patients who had only chemotherapy after surgery.
"The results show that radiation treatment should be considered for resected non-small cell lung cancer with involved mediastinal lymph nodes in addition to chemotherapy. The data observed in this study, however, needs to be confirmed in a prospective randomized trial of radiation, in addition to chemotherapy," Douillard said in a statement.
