Prostate cancers, in common with many other tumours, are often hypoxic; that is, they have low levels of oxygen. It is thought that tumour hypoxia may hasten the progression of cancers and make them more resistant to treatment. One previous study has suggested that hormone therapy, such as Casodex, may improve the prostate oxygen level. This study is designed to test that finding.

Further study details as provided by University Health Network, Toronto:

Primary Outcome Measures:
  • To determine the effect of neoadjuvant anti-androgen therapy on oxygenation of prostatic tumours, and to correlate with changes in PSA, hemoglobin level, and prostate volume.

Secondary Outcome Measures:
  • To enable study of the effect of neoadjuvant anti-androgen therapy on prostate tumour histopathology and gene expression, and correlation of these effects with changes in oxygenation.
