治療晚期攝護腺癌病患新藥可延長生命

05-06-2017

根據今天公布的兩項研究報告，晚期攝護腺癌病人除接受正規治療外，如增加使用一種新的抗荷爾蒙藥物，結果顯示可以減少死亡風險將近40%。

法新社報導，這種藥物是阿比特龍（abiraterone），楊森藥廠（Janssen Pharmaceuticals）有售，商品名為澤珂錠（Zytiga）。

其中一項研究發現，阿比特龍若與通常開給轉移性攝護腺癌患者服用的藥物潑尼松（prednisone）一起使用，死亡的風險減少了38%。

這項在美國臨床腫瘤學會（ASCO）年會上發布的報告又說，這種藥物也使得癌症惡化前的時間增加一倍有餘，由原本的14.8個月增至33個月。

這項臨床試驗包括34個國家的1200位病人，由2013年2月進行至2014年12月。

第二項臨床試驗涵蓋近2000位患者，結果發現在治療高風險的晚期攝護腺癌病人時，若除了標準的初步治療方法外再加上阿比特龍，也可以使相對死亡風險降低37%。

根據美國國家醫學圖書館（National Library of Medicine），比例高達92%的攝護腺癌病例能夠早期發現，也就是在腫瘤擴散到身體其他部分之前。不過，大約5%左右的患者被診斷出患病時，癌細胞已經擴散，治療前景欠佳。
