Prostate cancer is the most common type of cancer, and the ability to distinguish indolent from aggressive tumours remains one of the greatest challenges in the management of this disease. Most patients have multiple tumours in their prostate at the time of diagnosis. This is a complicating factor for developing biomarkers to aid in management of the disease.

The research projects primarily utilise a biobank with multiple frozen tissue cores from each of altogether 571 prostate cancer patients. The biobanking prodedure enables high-quality genomics analyses of multifocal primary prostate cancer, including analyses of interfocal heterogeneity of both gene mutations and gene expression (at gene level, alternative and aberrant splicing, and fusion genes).
