Popis: Purpose: The benefits of additional use of nimotuzumab (NTZ) in the treatment of locoregionally advanced nasopharyngeal carcinoma (LA-NPC) is largely unclear. We aim to compare LA-NPC treatment outcomes in patients that received CCRT with nimotuzumab (NTZ) to patients that received CCRT only.Materials and Methods: Between October 2009 and January 2012, 31 previously untreated and newly diagnosed LA-NPC patients were administered CCRT (3 cycles of 100 mg/m2 cisplatin every third week with intensity-modulated radiotherapy) plus NTZ according to an IRB-approved institutional research protocol. A well-balanced cohort of 62 patients who received CCRT alone was created by matching each patient who received CCRT plus NTZ via propensity-matched analysis in a 2:1 ratio.Results: Compared with CCRT only, CCRT plus NTZ was significantly associated with superior overall survival (5-year OS; 96.8% vs. 82.3%; P = 0.001), superior distant metastasis-free survival (5-year DMFS; 90.3% vs. 80.6%, P = 0.012) and superior progression-free survival (5-year PFS; 83.9% vs. 71.0%, P = 0.006). In multivariate analysis, the inclusion of NTZ to CCRT was confirmed to be a favorable factor for OS (HR, 0.31; 95% CI, 0.02–0.71; P = 0.027), DMFS (HR, 0.45; 95% CI, 0.13–0.77; P = 0.034), and PFS (HR, 0.38; 95% CI, 0.11–0.89; P = 0.041). In addition, no significant differences in hematology parameters, dermatitis, nausea, vomiting, xerostomia, nephrotoxicity or neurotoxicity were found between the two arms (all P > 0.05).Conclusion: The inclusion of NTZ to CCRT is more effective for long-term survival among LA-NPC patients than CCRT only.
