The present invention provides a method for predicting therapeutic effects of chemotherapy on hepatocellular carcinoma patients who have been treated with transarterial embolization and an antitumor agent for treating cancer patients who have been predicted to have a high probability of obtaining sufficient therapeutic effects from such chemotherapy. The present invention also provides a method for predicting therapeutic effects of chemotherapy on hepatocellular carcinoma patients who have been treated with transarterial embolization using the expression level of PDGF-BB or IL-8 as an indicator and an antitumor agent for treating cancer patients who have been predicted to have a high probability of obtaining therapeutic effects by such prediction method.本發明提供一種預測針對經實施肝動脈栓塞手術之肝細胞癌患者之化學療法之治療效果之方法、及用以對經預測為該化學療法顯示充分之治療效果之可能性高之癌患者進行治療之抗腫瘤劑。本發明係關於以PDGF-BB或IL-8之表現量為指標的針對經實施肝動脈栓塞手術之肝細胞癌患者之化學療法之治療效果預測方法、及用以對藉由該預測之方法而預測為顯示治療效果之可能性高之癌患者進行治療之抗腫瘤劑。
