The aim of the study was to evaluate the toxicity and efficacy of 62 patients with locally advanced nasopharyngeal carcinoma (NPC) (stage III, IVA, IVB) treated by three different modalities. Cisplatin was given weekly 35 mg/m(2)/day or every 3 weeks 100 mg/m(2)/day during radiotherapy (RT) in all patients. Patients were classified into following three groups: The patients in the group 1 (n = 23) were treated only with concurrent chemoradiotherapy (CCRT). In the group 2 (n = 15), before the CCRT, neoadjuvant chemotherapy, consisting of intravenous cisplatin and docetaxel on day 1, every 3 weeks treatment cycles was administered. In the group 3 (n = 24), adjuvant chemotherapy, consisting of cisplatin on day 1 and 5-flourouracil on day 1 to 5 every 3 weeks was used after CCRT. Three arms were treated with the same RT technique and dose. There was no difference for age, sex, and stage among the groups. Radiotherapy was administered in planned dose for all patients. A total of 82% patients completed planned chemotherapy concurrent with RT. The treatment related adverse effects were mild or moderate in intensity. There was no statistical difference between the groups regarding the treatment responses. Complete response rate of RT was 73.9%, 86.7%, and 87.5%, respectively. Median progression free survival (PFS) and overall survival (OS) were 13, 12, 9 months and 22, 20, 15 months for groups 1, 2, 3, respectively. No difference was observed in median OS and PFS among three groups. In our study, the efficacy and toxicity of neoadjuvant and/or adjuvant chemotherapy with CCRT and CCRT alone were found similar.
