<p>鼻咽位於喉嚨上方，在頭顱骨底部下方及鼻腔的後方，位置相當隱蔽。鼻咽癌 患者以男性居多，香港癌症資料統計中心的統計數字顯示，在2009至2017年期間， 鼻咽癌 一直為男性十大癌症。罹患鼻咽癌會有以下6大症狀:</p>



<ul><li>流鼻血</li><li>耳嗚</li><li>耳道流膿</li><li>聽力減退</li><li>頸側淋巴核脤大</li><li>持續性偏頭痛，晚間尢其嚴重</li></ul>

<p>近日香港大學李嘉誠醫學院研究團體發現新治療鼻咽癌的方法，源自γδ-T細胞的外泌體（Exosomes）協同放射治療，可克服鼻咽癌幹細胞對放射治療的抵抗力，並在免疫功能受到抑制的鼻咽癌微環境中保留其殺傷腫瘤和促進T細胞活性的作用，從而提升接近50%的療效。</p>

<p>外泌體能調控細胞之間信號傳遞的小細胞外囊泡，與細胞治療相比，外泌體具有更高的安全性，更容易保存和更低成本等優勢。在小鼠模型實驗中，部分患鼻咽癌的小鼠使用γδ-T細胞外泌體約100日，發現藥物有效控制鼻咽癌腫瘤生長並延長小鼠生存期，存活率可達一半。γδ-T細胞外泌體可有效針對就放射治療具抵抗力的CD44高表達（CD44+/high）的腫瘤幹細胞，並誘導其凋亡; 而無使用外泌體的對照組小鼠約50日後全部死亡。</p>
