此篇文章並非意圖貶損任何癌症的治療方法，純粹是轉述一宗失敗個案及其原因，探討從失敗中學習的過程。432Please respect copyright.ＰＥＮＡＮＡYGNn0vslxR

利用免疫治療法來對抗癌症，早前我們已經花了不少篇幅講述。432Please respect copyright.ＰＥＮＡＮＡM9jaOvjRz4

CAR T cell治療法，就是利用基因改造技術在免疫細胞外部加插辨識細胞的組件，引導它們更有效率殲滅對應的細胞;432Please respect copyright.ＰＥＮＡＮＡb0h5STOocD
在這個層面上，亦即是癌細胞。432Please respect copyright.ＰＥＮＡＮＡpYpz6OQJsY

(圖2)2010年，一名39歲女士患上腸癌，久經不同款式化療亦未見成效，故此便嘗試當時候較為新穎的CAR T cell 療法。432Please respect copyright.ＰＥＮＡＮＡI4nxmGb5XS

她的腸癌細胞表面被診斷出持有非常多的ERBB2蛋白質，所以其治療的方式便是從她身上取得免疫細胞，再在實驗室裡培植加插能夠辨認ERBB2蛋白質的CAR T cell，再以將這些CAR T cell注入她體內，盼望這些CAR T cell會殲滅腸癌細胞。432Please respect copyright.ＰＥＮＡＮＡSBq5ie5AoA

(圖3)不幸的是，注入CAR T cell後的15分鐘，她出現呼吸困難等症狀，隨之亦送入ICU作出治療，唯5日後亦與世祥辭。432Please respect copyright.ＰＥＮＡＮＡxqiAj3Sl0m

最後經驗屍及分析各種數據後，相信是因為肺部含有微量ERBB2蛋白質，在抵達癌細胞位置前，那些CAR T cell率先與持有ERBB2的肺部細胞結合，產生過量的免疫反應，引致肺部器官發炎及衰竭，導致氧氣沒能輸送至各器官位置。432Please respect copyright.ＰＥＮＡＮＡbRq521eHmD

在這手術進行之前，亦有不少針對ERBB2的CAR T cell人體試驗，箇中並沒有發生相同症狀。432Please respect copyright.ＰＥＮＡＮＡVvcgg4vrbO
432Please respect copyright.ＰＥＮＡＮＡ3t4OiRCd4y
這相信是因為是次手術為了希望能夠順利殲滅癌細胞，其注入的T cell數量被以往實驗過多，因此就連ERBB2含量不多的肺部細胞亦被牽涉在內。432Please respect copyright.ＰＥＮＡＮＡVdCmmZmysO
432Please respect copyright.ＰＥＮＡＮＡYKjK1SVG19
無論如何，從這之經驗中可得知，ERBB2顯然並不是一道針對癌細胞的理想對象。432Please respect copyright.ＰＥＮＡＮＡuRX9zKy5yu
