A randomised trial of Conventional care versus Radioablation (stereotactic body radiotherapy) for Extracranial oligometastases
Disease site: Breast cancer, lung cancer, prostate cancer.
Treatment modality: Radiotherapy
Status: In follow-up
CORE is a phase II/III, multicentre, non-blinded, parallel group randomised controlled trial in patients with breast, prostate or non-small cell lung cancer (NSCLC) primary cancer to evaluate if the addition of stereotactic body radiotherapy (SBRT) to standard therapy improves progression-free survival outcomes in patients with extra-cranial oligometastases.
Phase II of CORE aimed to recruit 230 patients over a period of three years. Participants were randomised to receive either standard care alone (115 patients) or standard care with SBRT (115 patients). Participants will be followed up for a further five years.
The phase II study aims to demonstrate:
- feasibility of recruitment
- deliverability of the study in a multi-centre setting and
- activity of SBRT, based on progression-free survival, across the three tumour types (breast, prostate and NSCLC).
If all three aims are achieved, CORE will roll into parallel, tumour-site specific phase III trials.
