Abstract ObjectiveTo investigate the clinical effect of hypedractionated accelerated radiotherapy(HART)combined with EP chemotherapy regimen in treatment of limited-stage small cell lung cancer(LS-SCLC).Methods50 patients of LS-SCLC treated in our hospital from January to December 2014 were selected as subjects,and they were divided into observation group and control group by random number table method,with 25 cases in each group.Control group was given three dimensional conformal radiation therapy and standard EP chemotherapy regimen,while observation group was given intensity modulated radiation therapy and standard EP chemotherapy regimen.After treatment for two months,the total treatment effective rate,progression-free survival,overall survival,two-year survival rate and safety were compared between the two groups.ResultsThe total treatment effective rate of observation group was higher than that of control group,and the difference was statistically significant(P<0.05).The progression-free survival,overall survival in observation group were longer than those in control group,and the differences were statistically significant(P<0.05).The two-year survival rate of observation group was 80.00%,which was higher than 52.00%of control group,and the difference was statistically significant(P<0.05).The incidence of adverse reactions were compared between the two groups,and the difference was not statistically significan(P>0.05).ConclusionHART combined with EP chemotherapy regimen in treatment of LS-SCLC can increase short-term efficacy,prolong survival time of patients and not add toxic-side effects,which is a safe and efficient treatment regimen.
