Method for evaluating and predicting the effectiveness of breast cancer treatment with long-acting topoisomerase I inhibitors

摘要

Provided is a method of treating an individual suffering from a cancer such as breast cancer by administering to the individual a long-acting topoisomerase I inhibitor such as SN-38 or irinotecan, and correlating the level of at least one tumor marker such as CA27.29 in the individual with response of the cancer to treatment with the long-acting topoisomerase I inhibitor, to thereby provide a method for predicting and assessing the therapeutic efficacy of the treatment.
