化療殺滅癌細胞的效率非常參差，有些情況更反而會導致癌細胞加速生長，究竟為何會這樣?759Please respect copyright.ＰＥＮＡＮＡba7JP6a1or

（圖2）使用化療藥物過後，某些癌細胞的確是會歸西死亡。759Please respect copyright.ＰＥＮＡＮＡjOT6vzypTa
而細胞死亡的方式有好幾種，其中兩種為Apoptosis及Necrosis。759Please respect copyright.ＰＥＮＡＮＡABmvVtLEaX

如圖中所見，進行Apoptosis的細胞會呈完整球狀，屍體相對的體積較大。759Please respect copyright.ＰＥＮＡＮＡ9h0mOL35Aa
而進行Necrosis的細胞則會分成為不規則的碎塊，體積亦較細。759Please respect copyright.ＰＥＮＡＮＡQ3L2TUxRNs

（圖3）形象化來說，Apoptosis就是曲奇餅，而Necrosis就是曲奇餅碎。759Please respect copyright.ＰＥＮＡＮＡmLaPKULKAj

（圖4）癌細胞被化療藥物殺死後，若進行Necrosis，鄰近沒受化療影響的癌細胞便會啟動一道名為Macropinocytosis的機制，將死亡的細胞吞噬，作營養供用使自己繼續成長，抵禦化療藥物所帶來的困境。759Please respect copyright.ＰＥＮＡＮＡlWf0YM34cW
759Please respect copyright.ＰＥＮＡＮＡKVFEc4Bi06
759Please respect copyright.ＰＥＮＡＮＡ2RFOGoTEhT
但細胞進行Apoptosis的話，因屍體體積過大，鄰近的細胞便不能把其吞噬。759Please respect copyright.ＰＥＮＡＮＡAqK6capntT
759Please respect copyright.ＰＥＮＡＮＡVGjLo9FcDc
並不是所有癌細胞亦能懂得施展Macropinocytosis，而整個機制學界亦在模索之中，只知道某些基因如PI3K或Ras進行突變的話，Macropinocytosis發生的機率亦會較大。759Please respect copyright.ＰＥＮＡＮＡOB3fGTq8QS
759Please respect copyright.ＰＥＮＡＮＡMs2jOTTioB
若能掌握整套機制及研發藥物制止Macropinocytosis的發生，並在化療藥物其間同時使用，便能壓抑癌細胞吞噬死亡細胞的機制，大大增加化療的效果。759Please respect copyright.ＰＥＮＡＮＡiyb2UKxaZt
