METHODS, KITS AND COMPOSITIONS FOR PROVIDING A CLINICAL ASSESSMENT OF PROSTATE CANCER

摘要

The present invention relates to prostate cancer signatures which are useful for providing a clinical assessment of prostate cancer from a biological sample of a subject. By performing initial gene expression studies on urine samples from prostate cancer and non-prostate cancer subjects, and using the PCA3/PSA prostate cancer test as a performance benchmark, the present inventors have surprisingly discovered multiple signatures that are informative in urine-based prostate cancer tests, as well as in tissue-based tests. The signatures relate to combinations of at least two prostate cancer markers whose expression pattern in urine has been validated as being associated (either positively or negatively) with a clinical assessment of prostate cancer. The prostate cancer markers can be used in conjunction with bioinformatics approaches to generate a prostate cancer score, which correlates with a clinical assessment of prostate cancer. Methods, kits and compositions relating to the aforementioned signatures are also described.
