A prospective randomised phase III study of observation versus screening MRI and pre-emptive treatment in castrate resistant prostate cancer patients with spinal metastasis.

Disease site: Prostate cancer, urological cancers

Intervention and treatment: MRI scan, followed by pre-emptive radiotherapy and/or surgery if needed

Status: Closed

Trial details

PROMPTS is a prospective, randomised, phase III, interventional study to determine whether detection of radiological spinal cord compression (SCC) using screening MRI of the spine and pre-emptive treatment could reduce the incidence of clinical SCC in asymptomatic castrate resistant prostate cancer patients with spinal metastasis.

541 patients will be recruited from UK sites over a 2–3 year period and randomised into one of two groups. Patients in the intervention group will receive a baseline screening MRI and pre-emptive treatment to any sites of radiological SCC; following the pre-emptive treatment, patients will receive an MRI scan every 6 months. Patients in the control group will be followed up as per standard practice. All participants will be followed up for a further 3 years.
