The FORECAST study has been assessing men with recurrent prostate cancer after prior radiotherapy. The study looked at the diagnosis / staging process to see whether a combination of MRI, PET-CT, Whole Body MRI and Bone scan could improve the detection of metastatic disease in these men. Furthermore men were treated with ablation using HIFU or cryotherapy and the study will assess the success of this treatment. We recruited 23 patients and are currently submitting all the follow-up data in readiness for the analysis.
