METHOD FOR EVALUATING EFFICACY OF TREATMENT FOR MALIGNANT NEOPLASM BY MEASURING AMOUNT OF CTDNA

摘要

The object of the invention is to provide a method for evaluating the efficacy of treatment for malignant neoplasm in a subject by measuring the amount of ctDNA in the subject. That is a method for evaluating the efficacy of treatment for malignant neoplasm in a subject, the method having (a) a step for measuring the amount of ctDNA in blood originating from the subject prior to the start of the treatment for malignant neoplasm, (b) a step for measuring the amount of ctDNA in blood originating from the subject after the start of the treatment for malignant neoplasm, and (c) a step for dividing the value obtained in step (b) by the value obtained in step (a).
