Aspirin Improve Survival of N2-3 Nasopharyngeal Carcinoma Patients

Nasopharyngeal carcinoma (NPC) is one of the most common maligancies of China. In the era of intensity-modulated radiotherapy (IMRT), the 5-year overall survival (OS) has now reached 85.0% or more. However, even after chemoradiation, the 5-year distant-metastasis rate of patients with N2-3 NPC is still 36.7%. Aspirin is proven in lab and clinical studies to have the abilities of inhibiting the inflammation which could enhance metastasis of breast and colorectal cancers. And before this study, it was discovered that regular aspirin intake might be associated with distant-metastasis-free survival (MFS) and OS independently. So this Phase 2 trial was conducted to validate the impact of aspirin on prognosis of N2-3 NPC.
