Patent ID: 7957910

Claim:
A method for predicting an effectiveness of chemotherapy using an anticancer agent, comprising steps of: measuring an activity of a cyclin dependent kinase 1 (CDK1) and an expression level of the CDK1, an expression level of a CDK2 and an expression level of a CDK4 included in a sample containing a tumor cell obtained from a human patient by a measuring device; calculating a specific activity representing a ratio of the measured CDK1 activity and CDK1 expression level by calculator; comparing a threshold value with the calculated CDK1 specific activity, comparing a second threshold value with the CDK2 expression level, and comparing a third threshold value with the CDK4 expression level; and predicting the chemotherapy is effective when the CDK1 specific activity is higher than the threshold value, or when the CDK1 specific activity is not higher than the threshold value, the CDK2 expression level is higher than the second threshold value, and the CDK4 expression level is higher than the third threshold value.
