Publication number: 20200392588Abstract: Described herein are method, compositions and kits for prognosis of prostate cancer. The methods include determining the ratio of PCA3 and of a prostate-specific marker expression in a urine sample and correlating the value of the PCA3/prostate-specific marker ratio with the aggressiveness and mortality risk of prostate cancer in the subject. The method for prognosing prostate cancer in a sample of a patient includes assessing the amount of a prostate cancer specific PCA3 mRNA and the amount of prostate-specific marker in the sample; determining a ratio value of this amount of prostate cancer specific PCA3 mRNA over the amount of prostate-specific marker; comparing the ratio value to at least one predetermined cut-off value, wherein a ratio value above the predetermined cut-off value is indicative of a higher risk of mortality of prostate cancer as compared to a ratio value below the predetermined cut-off value.Type: ApplicationFiled: August 24, 2020Publication date: December 17, 2020Applicant: Stichting Katholieke Universiteit, The University Medical Centre NijmegenInventors: Daphne Hessels, Gerald Verhaegh, Jack A.

Publication number: 20120309006Abstract: The invention relates to a method to diagnose prostate cancer by detecting a PCA3 sequence. In one embodiment the method and kit enables amplification of PCA3 RNA through an exon-exon junction of a spliced PCA3 mRNA, and methods and kits to detect an amplified PCA3 RNA, using a probe which spans the amplified exon-exon junction. The methods and kits can detect a PCA3 RNA lacking one intron or more. Also provided are methods of detecting PCA3 RNA expressed in non-prostate tissue or cells of the urinary tract, which comprises PCA3 intron 3. In addition, methods are provided to determine whether a sample from a subject contains or lacks prostate cells, by performing a hybridization and/or amplification reaction on RNA from the sample to detect the presence or level of PCA3 RNA that lacks at least one intron and distinguishing a prostate cell from a non-prostate cell.Type: ApplicationFiled: August 2, 2012Publication date: December 6, 2012Inventors: Jack A.
