        大致上,癌症病患通常都會在某個時期接受某種化學治療療程 ( 包括晚期或轉移性癌症 )。但很不幸的是,一旦癌細胞開始轉移擴散, 且部分細胞擁有抗藥特質,是當今臨床癌症化療的一項重大障礙,也是癌症病患最主要的死因之一。

        本質上,癌症化療的成功與否,主要受兩個因素 影響固有內在因素及改編癌細胞因子。簡單來說,固有內在因素可以說是不同病人對癌細胞本身,或抗癌藥物先天上所擁有的不同反應。這包括不同病人對於各種藥物的充分吸收、分佈代謝及移除等反應。至於改編癌細胞因子,則是強調腫瘤細胞依賴各種方法,來應對不同類型的藥品,並存活下去。 由於癌細胞在不同組織的起源及基因調整均具多樣性,因此對治療藥物的反應亦有所不同。 尤其在藥物治療後,癌細胞經常改變,導致對於藥物敏感性的變化。癌細胞的抗藥機制可概括為以下 6 種類型:( 1 ) 減少、喪失或變更藥物標靶,( 2 ) 加強藥物代謝,( 3 ) 增強細胞修復機制,( 4 ) 降低藥物的吸收,( 5 ) 加強藥物外排,( 6 ) 藥物隔離。癌細胞往往會以前三種機制來對抗 ( 無論是在結構或功能 ) 同一類的藥物。不同的是,癌細胞若以後三種機制將直接改變腫瘤細胞內各種藥物的累積,並導致多重抗藥性癌細胞的產生。不過,雖然癌細胞能運用不同途徑來達成多重抗藥機制,能源依賴性的藥物運輸系統,仍是最常見的多重抗藥機制。  

        在癌細胞高度表達 ATP-binding cassette ( ABC ) transporters,基本上是使細胞對化療產生耐藥性,為其中非常重要的一個機制,也是癌細胞對抗藥物的第一道防線。這方式是降低癌細胞內的藥物濃度最直接也最有效的方法。目前已有 15  ABC transporters,被證實與多重抗藥性腫瘤的引發有很大的關聯性。這些跨膜幫 浦運用 ATP 水解的能源來運輸多種藥物跨越癌細胞膜。以臨床癌症化療來說,在多重抗藥性癌細胞內高度表達的 ABC transporters 中,有 3 個最為主要的 ABC 藥物 transporter,即 P-glycoproteinMRP1,和 ABCG2,這些 ABC transporters 的大量表現與運作會直接使癌細胞產生多重抗藥性的現象,也影響必須進入中樞神經系統的口服藥物例如:癲癇藥物 ) 之輸送與吸收,扮演著保護癌幹細胞的角色。

        總之,如何解決 ABC 藥物 transporter 所造成的多重抗藥性問題,將是邁向成功癌症化療的第一步。近幾年研究指出,運用抑製劑來直接抑制 ABC transporters 的功能與表達,是解決抗藥性最簡易的方式。但是目前在於尋找高效率、低毒性的抑製劑進展十分緩慢。過去發展出來絕大部份的抑製劑,也都因為偏高的內在毒性而宣告失敗。因此,在未來篩選出有潛力的化學結構與發展多功能抑制藥物,在治療多重抗藥性癌症細胞上、提高藥物穿過血腦屏障的滲透力與藥物敏感性上,都具有很大的臨床意義。
