Abstract
肝細胞癌(Hepatocellular carcinoma, HCC)是全球第六大流行的癌症類型,也是第三大致命癌症。由於早期肝癌沒有症狀的原因,許多肝癌患者直到晚期階段才被診斷,而此時患者會接受多重酪胺酸激酶抑制劑如Sorafenib的標準治療。然而,僅有少部分病患對Sorafenib有治療反應,且許多患者在接受治療後6個月內就會出現Sorafenib抗藥性。另外,約六成的晚期及末期肝癌的病患會表現惡病質,其臨床表現包括骨骼肌肉萎縮和體重減輕,並會降低Sorafenib治療效果與耐受性,進而降低患者存活。從先前文獻中已知發炎細胞因子在癌症的惡病質中扮演重要角色。在本論文中,我們認為Sorafenib抗藥性的肝癌細胞會分泌更多發炎因子,進而促進肝癌惡病質。目前為止,我們分析我們實驗室建立的Sorafenib抗藥肝癌細胞株,發現在一些Sorafenib抗藥的肝癌細胞株中,會有較高的發炎因子表現,而這些抗藥性細胞株所收集的條件培養液會造成小鼠C2C12肌小管的萎縮。在動物實驗中,我們也發現帶有抗藥性細胞腫瘤的小鼠其肌肉纖維有顯著萎縮。此研究反應出Sorafenib抗藥性的產生可能會惡化晚期肝癌的惡病質表現。
