The purpose of the present invention is to provide a method for predicting the effectiveness of an angiogenesis inhibitor in a subject suffering from a tumor. Provided is a method comprising a step of testing for the presence or absence of an a mutation or loss of expression of B-Raf and PTEN in a sample of tumor tissue from the subject. By using the presence or absence of or a mutation or loss of expression of B-Raf and PTEN as an indicator, this method enables the antitumor effectiveness of the angiogenesis inhibitor to be predicted without administering the angiogenesis inhibitor to the subject.
本发明的目的是提供一种预测血管生成
抑制剂对肿瘤患者疗效的方法。本发明提供的方法包括检测受试者肿瘤组织样本中是否存在 B-Raf 和
PTEN 的突变或表达缺失。通过使用B-Raf和
PTEN的存在或不存在或突变或表达缺失作为指标,该方法能够在不对受试者施用血管生成
抑制剂的情况下预测血管生成
抑制剂的抗肿瘤效果。
