Abstract:
Objective To compare image-guided radiotherapy(IGRT) and intensity-modulated radiotherapy(IMRT) treatment in patients with recent efficacy and toxicity of radioactive reaction ,discuss factors affecting prognosis .Methods Collection of 52 cases of IGRT and 55 cases of IMRT patients with non-small-cell lung cancer(NSCLC) ,satisfy the requirement of target prescription dose in the case ,the recent efficacy of tumor ,comparing two treatments in patients with radioactive toxic effects and factors affect-ing the prognosis .Results The incidence of radioactive pneumonia in IGRT group was lower than the IMRT group (P<0 .05) ,the incidence of radiation esophagitis had no statistical differences in the two groups (P>0 .05) .The survival rates of IGRT group 1 , 1 .5 ,2 years after radiotherapy were 57 .7% ,35 .0% ,27 .3% ,IMRT group were 50 .9% ,34 .1% ,21 .8% .The median survival time of IGRT group and IMRT group was 17 months and 13 months respectively ,there was no statistically significant difference(P>0 .05) .Conclusion In NSCLC treatment ,compared with IMRT ,TGRT could reduce the toxic reaction of radiotherapy ,but the effect of two kinds of treatment for the recent difference is not obvious .
