Three-dimensional conformal hypofractionated high-dose radiotherapy for non-small cell lung cancer in the elderly

Lang Feng-pin

Abstract

Objective To discuss the effect of three-dimensional conformal hypofractionated high-dose radiotherapy on non-small cell lung cancer in the elderly. Methods All patients were treated by the same way of fraction radiotherapy,with a prescription dose of 4-5?Gy,every other day,to a total dose of 48-55?Gy. Results Complete response was observed in 23(51.1%) patients,partial response in 15(33.3%) patients, with the overall response rate of 84.4%. The overall 1-,2-,3-year survival rates were 66.7%,48.9% and 39.1%.Conclusions Three-dimensional conformal hypofractionated high-dose radiotherapy is safe and effective, giving mild untoward side-effects.
