简要总结

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.

详细描述

Arm 1 of this study will aim to determine the association between hypoxia in the primary tumour with the presence of skeletal metastases and aim to determine if hypoxia is also present in the metastatic sites themselves. Arm 2 will aim to determine the genetic changes associated with hypoxia in cancers that have not spread outside the prostate. Hypoxia presence will be determined by using a hypoxia identifying stain (by giving a patient a tablet of the stain to take orally) and by identifying genomic alterations that are associated with hypoxia. After taking the tablet of the hypoxia marker (Pimonidazole) patients in Arm 1 will receive both a biopsy of the prostate and of one or two of the bone metastases. The presence or not as well as the degree of hypoxia in both sites will be assessed. Patients in Arm 2 will receive pimonidazole prior to a planned radical prostatectomy and the heterogeneity of hypoxia related genetic change throughout the prostate will assessed. Arm 2 patients will undergo MRI hypoxia imaging to validate the detection of pimonidazole marked hypoxic regions with a non-invasive imaging method.

  • *e.g. safely to biopsy and expectably providing sufficient tissue yield World Health Organisation (WHO) performance status 0 to 2 with no deterioration over the previous 2 weeks and minimum life expectancy of 12 months
  • No prior local and/or systemic treatment for localised prostate cancer
  • Willing to donate cancer tissue samples for research purposes (bone metastasis and primary tumour)

排除标准

  • Involvement in the planning and/or conduct of the study (applies to staff at the study site)
  • Previous enrolment in the HYPROGEN study
  • As judged by the investigator, any evidence of severe or uncontrolled systemic disease (e.g. uncompensated respiratory, cardiac, hepatic or renal disease)
  • Evidence of any other significant clinical disorder or laboratory finding that made it undesirable for the patient to participate in the study
  • Any investigational agents or study drugs from a previous clinical study within 30 days of the first tissue collection
  • Prior treatment of localized prostate cancer including radiotherapy and/or androgen-deprivation therapy
  • Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements
  • Contra-indications to MRI (incl. pacemakers etc.)
  • Bone metastases in difficult to reach areas or areas which might be at risk for pathological fracture post biopsy as judged by biopsying radiologist / chief investigator
