An object of the present invention is to provide a chemotherapy using a PI3K/AKT/mTOR inhibitor that produces an excellent antitumor effect on a cancer patient. The present invention provides a method for predicting the therapeutic efficacy of the chemotherapy using the antitumor agent comprising a PI3K/AKT/mTOR inhibitor on a cancer patient on the basis of the expression level of PHLDA1 and/or PIK3C2B in a biological sample containing tumor cells isolated from the cancer patient.
本发明的目的是提供一种使用
PI3K/AKT/mTOR
抑制剂的化疗方法,该化疗方法可对癌症患者产生极佳的抗肿瘤效果。本发明提供了一种方法,可根据从癌症患者体内分离出的含有肿瘤细胞的
生物样本中 PH
LDA1 和/或
PIK3C2B 的表达
水平,预测使用包含
PI3K/AKT/
mTOR 抑制剂的抗肿瘤剂的化疗对癌症患者的疗效。
