Method for detecting DLX1 mRNA, HOXC6 mRNA, and KLK3 mRNA in a urine sample and predicting and treating clinically significant prostate cancer

摘要

The present invention relates to methods, devices, combinations, kits, and systems for predicting and treating clinically significant prostate cancer in a urine sample of an individual suspected of suffering from prostate cancer based on expression analysis of normalized prostate tumor markers. The present methods, devices, combinations, kits, and systems are especially suitable for predicting and treating prostate cancer with a Gleason score of seven or more in individuals with a serum prostate-specific antigen (sPSA) level lower than 15 ng/ml. Specifically, the present invention relates to methods, devices, combinations, kits, and systems for predicting and treating clinically significant prostate cancer in a urine sample of an individual suspected of suffering from prostate cancer, the method comprises the steps of: a) determining mRNA expression levels of one or more of the genes DLX1, HOXC6, TDRD1 and KLK3 in a urine sample of said individual; b) normalizing the mRNA expression levels of one ore more of DLX1, HOXC6, and TDRD1 using the mRNA expression level of KLK3; and c) establishing clinically significant prostate cancer based on a combination of the KLK3 normalized expression levels of the combination of one or more of DLX1, HOXC6, and TDRD1. Treatment for prostate cancer may be administered based on the expression levels of one or more of DLX1, HOXC6, and TDRD1.
