要通過癌症藥物臨床研究，其中的一道標準就是藥物有高度效率殺滅癌細胞。467Please respect copyright.ＰＥＮＡＮＡV6VoD2IstP

追求高效率無可厚非，但以這個例子中，101個病人中，只有1人見效，是否真的代表要放棄這藥呢?467Please respect copyright.ＰＥＮＡＮＡf9tHh3uiaq

（圖2）在一次Phase2臨床研究中，Everolimus藥物未能在大部份病人中見得到成效，唯獨在一名病人中出現奇效。467Please respect copyright.ＰＥＮＡＮＡ2721Oll8DS

圖中紅箭嘴所指的位置為腫瘤所在地。用藥6個月後，腫瘤完全消失，情況一直持續至2年半有多。467Please respect copyright.ＰＥＮＡＮＡrfXStf68QY
467Please respect copyright.ＰＥＮＡＮＡhoBeOFO5FI
這個情況下，又是否應該放棄這藥物，就這樣以奇蹟二字來解釋此事作罷呢?467Please respect copyright.ＰＥＮＡＮＡvP8AkAqxV0

（圖3）有科學家死心不惜(Ref1)，致力研究那名病人為何會對此藥作出如此正面的效果。467Please respect copyright.ＰＥＮＡＮＡttTjHqRsYp

最後確認原因是那名病人同時在兩道基因NF2及TSC1出現變異，引致該藥物的機制更能有效針對癌細胞。467Please respect copyright.ＰＥＮＡＮＡHI473Hkw0J
467Please respect copyright.ＰＥＮＡＮＡ4LJfaxAnft
那場臨床研究主要是針對膀胱癌病人，而膀胱癌同時會出現這兩種基因變異的機率非常之低，因此研究結果非常參差。467Please respect copyright.ＰＥＮＡＮＡzHryyCXq1Z
467Please respect copyright.ＰＥＮＡＮＡ6JFV0SON6l
但是，倘若將來有其他癌症病人同時擁有這兩道基因變異呢?467Please respect copyright.ＰＥＮＡＮＡhUklcDhmU5
如果此藥物能有效應付出現這兩道變異基因的癌症，那麼藥物是否還是值得推出市場呢？467Please respect copyright.ＰＥＮＡＮＡDQJuymgal8
467Please respect copyright.ＰＥＮＡＮＡUjEQEWatIm
無論如何，此藥最後在2012及2018年被FDA認可，可用作醫療與TSC基因變異有關的症狀。467Please respect copyright.ＰＥＮＡＮＡskNlVQi07v
那份科學家死心不惜的研究是否有作出相關功勞，並沒有真接證據可顯示得到。467Please respect copyright.ＰＥＮＡＮＡPp7b7uNhju
467Please respect copyright.ＰＥＮＡＮＡ7x5cIO9ZCG
但這份研究明顯地帶出了一道訊息，就算新藥沒能對大部份的病人見效，亦是值得擺放努力剖析為何會對小部份人見效，分分中可能會有意外的收獲，增進開放藥物的新方向。467Please respect copyright.ＰＥＮＡＮＡvtM7XFYqtj
