First Claim
Patent Images
1. A method for detecting circulating tumor cells in a mammalian subject suspected of having cancer comprising:
- obtaining a test sample from blood of the subject, the test sample comprising a cell population,mounting the test sample on a substrate,detecting the presence or absence of a first marker in the test sample that selectively binds to the circulating tumor cells,detecting the presence or absence of a second marker in the test sample that binds to the cell population or a subset of the cell population, andanalyzing the cell population detected by the first and second markers to identify and characterize the circulating tumor cells.

47. A method of screening a drug candidate compound for treatment of cancer in a mammalian subject,
administering a therapeutically effective amount of the drug candidate compound to the subject suspected of having cancer, obtaining test samples from blood of the subject before and after treatment with the drug candidate compound, the test samples comprising a cell population suspected of containing circulating tumor cells, mounting the test samples on a substrate, detecting the presence or absence of a first marker in the test samples that selectively binds to the circulating tumor cells, detecting the presence or absence of a second marker in the test samples that binds to the cell population or a subset of the cell population, and analyzing the cell population detected by the first and second markers to identify the circulating tumor cells in the test samples before treatment with the drug candidate compound compared to after treatment with the drug candidate compound, wherein the presence of a decreased number of the circulating tumor cells in the specimen after treatment compared to a number of the circulating tumor cells in a specimen before treatment indicating effectiveness of the drug candidate compound in treating the cancer in the mammalian subject.
