Radiation-related nasopharyngeal necrosis (RRNN) is a rare and often fatal complication in patients with nasopharyngeal carcinoma (NPC). Currently, no standard treatments are recommended for RRNN. The effects of traditional conservative treatments are suboptimal, and surgery for RRNN cannot be performed by inexperienced doctors. In the present study, the use of Endostar in two patients with RRNN was evaluated. Two patients with RRNN were treated at the Department of Oncology, Panyu Central Hospital (Guangzhou, China). Endostar was administrated (15 mg/day from day 1 to day 7, every three weeks) intravenously for four and seven cycles in a male and a female patient, respectively. The effects of Endostar were assessed using magnetic resonance imaging (MRI) and a nasopharyngoscope. The symptoms of RRNN in both patients were relieved after treatment with Endostar. MRI and nasopharyngoscope analysis revealed that necrosis of the nasopharynx was substantially decreased and nasopharyngeal ulcers were healed. Endostar has the potential to be a novel, effective therapy for the treatment of patients with RRNN. However, clinical trials are required to confirm the results of the present study.
