Objective To evaluate the clinical efficacy and toxicity of simultaneously integrated boost intensity-modulated radiotherapy (SIB-IMRT) for patients with locally advanced non-small cell lung cancer (NSCLC).Methods Patients with NSCLC who received SIB-IMRT from January 2008 to June 2011 in our hospital were retrospectively analyzed.Among the 78 patients,45 patients had clinical stage ⅢA disease,33 patients ⅢB disease.The SIB-IMRT plans were designed to deliver 50.4-64.0 Gy in 28-33 fractions (1.8-2.1 Gy/fraction) to PTV while simultaneously delivering 60.0-74.3 Gy in 28-33 fractions (2.0-2.5 Gy/fraction) to IGTV.The primary endpoint was overall survival (OS).The secondary endpoints were overall response rate (ORR),local control rate (LCR),progression-free survival (PFS),adverse events (AEs).Results All patients completed definitive radiotherapy and 67 (85.9%) patients received platinum-based doublet chemotherapy.Among them,17 (21.8%) received concurrent chemoradiation,other 50 (64.1%) received sequential chemoradiation.The ORR was 69.2%(54/78),with CR 11(14.1%),PR43(55.1%),SD22(28.2%),PD2(2.6%).The follow-up rate was 92.3%.Among 72 patients who were followed up,50 were dead,22 were alive.1,2,3-year LCR were 88.4%,54.7%,28.6%.Median OS and PFS were 27.3 months(5.8-49.3 months),15.3 months (2.3-46.8 months),respectively.1,2,3-year OS and PFS were 87.5%,50.7%,56.6%,27.6%,30.3% and 21.1%,respectively.There was a statistically significant difference in OS between the subgroup arms with concurrent chemoradiation or non-concurrent chemoradiation (x2 =3.946,P < 0.05).Nineteen (24.4%) patients experienced acute grade 3 esophagitis and 9 (11.5%) experienced acute grade≥3 treatment-related pneumonitis (TRP).There were 2 (2.6%) late grade 3 pulmonary toxicity after 1-year follow-up.No late grade ≥ 3 esophageal toxicity was observed.Conclusions It is safe and workable to use SIB-IMRT to treat patients with NSCLC.More prospective clinical studies are warranted.
