The treatment option in patients with platinum-resistant relapsed or metastatic nasopharyngeal carcinoma is limited. Previous studies showed that both S-1 and oxaliplatin were effective in head and neck cancer. Moreover, SOX (S-1 plus oxaliplatin) was proved to be tolerable in advanced stage gastric cancer. Therefore, we aim to evaluate this regimen in salvage setting of nasopharyngeal carcinoma.
The aim of the study is to evaluate the efficacy and safety of SOX regimen (S-1 plus oxaliplatin) as salvage treatment in patients with relapsed or metastatic nasopharyngeal carcinoma.
