癌症是導致死亡的主要原因,根據世界衛生組織的估計,到了2025年,全球每年將有1140萬人死於癌症。找出有效的抗癌療法仍然是現代醫學研究的重大挑戰。過去數十年間,科學家對此議題的重視,投入免疫治療的開發,以提高包括放射線治療和化療在內的傳統療法之療效和安全性。

近年來,以樹突細胞(DC)和細胞因子誘導的殺手細胞(CIK)合併使用的細胞免疫療法(DC-CIK)逐漸被重視。

免疫細胞的取得是從病人的周邊血液中分離出來,經由體外共同培養、增殖,將活化的免疫細胞群回輸入患者體內。Shuo Wang的團隊整理關於DC-CIK治療實體腫瘤的最新文獻和臨床試驗,發表了回顧性論文(review article),文章提到該療法針對不同的腫瘤類型(包括神經膠母細胞瘤、肺癌、乳癌、胃癌、胰臟癌、肝癌和腎臟癌)之臨床試驗正在蓬勃展開。

 

這篇文獻指出,接受DC-CIK合併化療的癌症患者,其整體存活期明顯優於只接受化療的病人。

此外,今年發表的一篇個案報告,帶來令人振奮的消息,一名患有肺部和縱隔腔轉移的鼻咽癌病人在接受化放療與DC-CIK的合併治療後,具有良好的臨床反應。

在長達13年的追蹤期中沒有發現腫瘤復發或轉移的跡象。目前持續累積的研究數據顯示,DC-CIK細胞療法具有潛力以克服癌症的高致死率。

 

根據Shuo Wang團隊的文章顯示,在治療腫瘤的臨床研究中,有171項是用免疫細胞療法(adoptive cell therapy),其中38項是採用DC-CIK的合併療法。

DC-CIK細胞療法在未來勢必能夠為癌症治療領域開啟新的篇章。
