鼻咽癌(nasopharyngeal carcinoma,NPC)是我国常见的恶性肿瘤之一,年发病率为10~25/10万,而广东省的鼻咽癌患者占了国内的60%。放射治疗被公认为鼻咽癌首选治疗方法。在鼻咽癌的放疗中经常会遇到放疗后肿瘤复发、放射抗拒等问题,而χ或γ射线等在杀死癌细胞的同时也对肿瘤组织?
Nasopharyngeal carcinoma (NPC) is one of the most common malignant tumors in our country. The annual incidence is 10-25 / 100,000, while that of Guangdong province is 60% of that in China. Radiation therapy is recognized as the preferred treatment of nasopharyngeal carcinoma. In the radiotherapy of nasopharyngeal carcinoma often encounter tumor recurrence after radiotherapy, radiation resistance and other issues, and χ or γ-rays kill cancer cells at the same time on the tumor?
