Observation on efficacy of concurrent chemoradiation in locally advanced non-small cell lung carcinoma

Abstract

Objective To compare the efficacy and toxicities of concurrent chemoradiation(radiotherapy combined with PTX and DDP) with sequence chemoradiation(chemotherapy followed by radiotherapy) in locally advanced non-small cell lung cancer(NSCLC). Methods Sixty-seven patients with stage Ⅲ NSCLC were randomly divided into two groups. Concurrent chemoradiation group, chemotherapy started at the first day of radiotherapy, sequence group, four cycles chemotherapy followed by radiotherapy alone. Results Short time response rate(CR+PR) in concurrent group was 80.6%, 55.6% in sequence group(χ2=5.74,P=0.02). Hematology toxicities and radioactive esophagitis were much more severe than those in sequence group, however, most patients could tolerate after treatment.Conclusions Although more tolerated toxicities, concurrent chemoradiation(radiotherapy combined with PTX and DDP) is better than sequence chemoradiation(chemotherapy followed by radiotherapy) in locally advanced non-small cell lung carcinoma.
