Locally recurrent nasopharyngeal carcinoma (NPC) may be salvaged by intensity modulated-radiotherapy (IMRT), but severe late toxicities become the most common reason of death in IMRT salvaged NPC patients.~The aim of this phase II randomized controlled study is to address the efficacy of concurrent Endostar (Endostatins) with IMRT to reduce the occurrence of severe late toxicities compared with IMRT alone for locally recurrent NPC patients.
The purpose of this study is to determine whether endostar and IMRT is effective in the treatment of locally recurrent nasopharyngeal carcinoma patients compared with IMRT alone.
