  • Patent number: 10725053
    Abstract: Methods are provided for treating a subject with prostate cancer and/or diagnosing a subject at risk for prostate cancer, which can include measuring increased expression of at least two prostate cancer-related molecules in a sample obtained from a subject, including the prostate cancer-related molecules AGR2, AGR3, CRISP3, CCL3, CEACAM5, CEACAM6, IL24, MMP9, CXCL14, CD90, POSTN, and SFRP4. The methods can include administering at therapy to a subject with prostate cancer. Methods are provided for treating a subject with intermediate- or high-risk prostate cancer, which can include measuring increased expression of MMP9 in a sample obtained from a subject compared to a control representing expression of MMP9 expected in a sample from a subject who has low-risk prostate cancer.
