Hypoxia-driven Prostate Cancer Genomics (HYPROGEN)

Due to the rapid growth, tumour demand for oxygen is often higher than what can be delivered by the newly forming blood vessels. Tumour adaption to this imbalanced oxygen supply and demand (hypoxia) is associated with poor prognosis and genetic changes (genomic instability) that allow it to become more resistant to chemo- and radiotherapy. Patients with hypoxic tumours therefore die earlier. Limited information is available on hypoxia in newly diagnosed prostate cancer, especially to what degree hypoxia in the prostate tumour is associated with the presence of metastases to bones. The Hyprogen trial is a prospective, non-randomised, exploratory biopsy and imaging biomarker study recruiting 60 patients with prostate cancer to better establish the role of hypoxia in prostate cancer cells evolution and early metastatic spread.
