Abstract
Objective To investigate the results and toxic effect of three-dimensional conformal radiotherapy(3DCRT)for non-small-cell lung cancer.Methods 112 cases with stage Ⅲ non-small-cell lung cancer were randomly divided into two groups 56 in 3DRCT group and 56 in conventional group.In treatment group,patients were fractionated 3DRCT every other day and 4 ~ 8Gy every time.Total dosage were 40 ~ 70Gy.Results In 3DRCT group,the overall response rate was 67.8%(CR+PR)and complete remission rate was 32.1%(CR)while conventional group was 28.6% and 3.6%.respectively 3DRCT group was higher(P< 0.05).Conclusion Three-dimensional conformal radiotherapy can increase the survival rate of patients and ease the toxic effect of chemotherapy.In a word,it' s an effective way to treat nonsmall-cell lung cancer. Key words: Conformal radiotherapy; Non-small-cell lung cancer
