OBJECTIVE: This study was conducted to assess the efficacy and safety of nimotuzumab combined with radiotherapy (RT) in elderly patients with nasopharyngeal carcinoma. MATERIALS AND METHODS: The clinical data of 75 nasopharyngeal carcinoma patients, who were initially treated with nimotuzumab combined with RT, were collected and retrospectively reviewed from December 2008 to April 2014. They were aged 60 to 81 years (median 64 years). The distribution of disease was stage II in 10 (13.3%), stage III in 33 (44.0%), and stage IV in 32 (42.7%). Among these patients, 59 cases received cisplatin-based chemotherapy. Survival outcomes and treatment toxicity were analyzed using IBM SPSS 19.0 software. RESULTS: With a median follow-up of 45 months (range, 13-78 months), the estimated 3-year local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), distant metastasis-free survival (DMFS), progression failure-free survival (PFS), and overall survival (OS) rates were 95.6%, 95.5%, 98.6%, 89.7%, and 89.2%, respectively. In the subgroup, 3-year OS rate in the patients with concurrent chemotherapy was 90.5% and 77.4% in patients without concurrent chemotherapy (Log-Rank = 1.795, P = .180). Univariate analysis showed that T stage and clinical stage were correlated with OS. Multivariate analysis indicated that age, T stage and tumor response at the end of treatment were independent prognosticators. Nine patients experienced grade 3 to 4 acute mucositis and 26 patients experienced grade 3-4 leukocytopenia, with no cases of skin rash and infusion reaction. Twelve patients developed mild liver function damage. No serious gastrointestinal or renal toxicities were observed. CONCLUSION: The efficacy of combined nimotuzumab with RT in elderly NPC patients was encouraging and the toxicities were accepted. In addition, nimotuzumab provides a better option for elderly patients who cannot be tolerate chemotherapy. |
