Nasopharyngeal carcinoma (NPC) is a head and neck tumor. Studies have shown that more than 70% of patients are diagnosed with locally advanced nasopharyngeal carcinoma at the time of initial diagnosis. The 3-year survival rate of locally advanced nasopharyngeal carcinoma after chemotherapy is over 90%, but 30% of patients still have recurrence and distant metastasis. Therefore, while improving the level of radiation therapy technology, we should study multidisciplinary comprehensive treatment methods and put forward the biological concept of "cure". Induction chemotherapy can effectively create better radiotherapy conditions for locally advanced nasopharyngeal carcinoma, especially for patients with large lesions, improve the treatment response rate, and may reduce the local recurrence and distant metastasis rate. After the end of neoadjuvant chemotherapy, compared with patients who only reached SD, patients who reached CR had a significant survival benefit; Other patients had a reduced rate of distant metastasis, which aroused our interest, although there was no obvious survival benefit. The national multicenter phase II clinical study showed that nitumab combined with radiotherapy significantly improved the 3-year survival rate of patients with locally advanced nasopharyngeal carcinoma compared with radiotherapy alone. According to the previous related research results, nitumab combined with induction chemotherapy or concurrent chemoradiotherapy has a certain effect on nasopharyngeal carcinoma without obvious adverse reactions. However, prospective studies on the short-term efficacy and safety of local advanced nasopharyngeal carcinoma combined with induction chemotherapy and concurrent chemoradiotherapy are still lacking (Taisheng ®）。
