Brief Title: Conventional Care Versus Radioablation (Stereotactic Body Radiotherapy) for Extracranial Oligometastases
Official Title: A Randomised Trial of Conventional Care Versus Radioablation (Stereotactic Body Radiotherapy) for Extracranial Oligometastases
Study ID: NCT02759783
Brief Summary: Metastatic spread of cancer from its primary site to distant organs is the commonest cause of death from cancer. The term oligometastases describes an intermediate metastatic state, in which cancer exists as a limited number of metastases at first, before cells acquire the ability to metastasise more widely. For the large majority of solid cancers, once metastatic disease has been diagnosed the chances of cure are small. There are several situations where this is not the case, but it is not known if stereotactic body radiotherapy (SBRT) for oligometastatic disease will alter outcomes or whether the toxicity burden of this treatment is justified. SBRT is targeted radiotherapy which destroys cancer cells in the area of the body it is aimed at however low dose radiation may be received by surrounding tissue. It is difficult to quantify incidence of patients with multiple primary cancers developing at intervals that are representative of oligometastatic stage IV disease, (defined for the purposes of this trial as ≤ 3 metastatic sites). However an increase in the use of surveillance imaging, together with improved diagnostic sensitivity has led to the diagnosis of patients with asymptomatic oligometastatic relapse becoming a more common clinical occurrence. The CORE study is a randomized controlled trial that will be conducted in patients with cancer in one of three primary sites where oligometastatic disease relapse is a common clinical scenario: breast, prostate and non-small cell lung cancer (NSCLC). The study will evaluate the use of SBRT in this patient population. Eligible patients who consent to participate in this clinical trial will be randomized to receive standard care or standard care plus SBRT we hope to recruit approximately 206 patients to the study and the primary outcome measure is progression free survival.
Detailed Description: CORE is a phase II/III, multi-centre, non-blinded, parallel group randomised controlled trial in patients with breast, prostate or NSCLC primary cancer comparing standard of care (SOC) with or without SBRT for extra-cranial metastases. The aim of the phase II study is to demonstrate 1) feasibility of recruitment, 2) deliverability of the study in a multi-centre setting and 3) activity of SBRT, based on progression free survival, across the three tumour types. If all three aims are achieved the trial will be amended to roll into parallel tumour-site specific phase III trials. Eligible patients are those with either primary breast, prostate or NSCLC who have presented with ≤3 extra-cranial, metachronous, oligometastases, all suitable for SBRT. Patients will be randomised in a 1:1 ratio to either SOC or SOC with the addition of SBRT. Choice of SOC treatment is at the discretion of the local oncologist and defined per patient prior to randomisation (see section 8). Patients randomised to SBRT+SOC will receive a dose and fractionation regimen dependent on the metastatic site and proximity to dose limiting organs and normal tissues. Treatment will take place within 6 weeks of randomisation. The average scheme would be 3 treatments over 5 days but the maximum period of SBRT duration could be 8 treatments over 19 days. All patients will be reviewed every 3 months with a clinical examination and tumour markers (where applicable) during years 1 and 2, and 6 monthly thereafter to 5 years. Staging and follow up imaging protocols will be tumour type dependent: * Breast: 3 monthly CT scans for years 1 and 2, and 6 monthly thereafter to 5 years. * NSCLC: 3 monthly CT scans for years 1 and 2, 6 monthly to year 3, then annually to 5 years. * Prostate: CT scans will be performed at 6, 12 and 24 months with imaging triggered by appropriate PSA rises. A rising PSA defined as 2 successive PSA rises from nadir, measured a minimum of 4 weeks apart. If the overall PSA rise has a doubling time of ≥ 3 months or the PSA level has doubled the original PSA value at trial entry or if clinically indicated, then restaging should be considered. All patients will have a toxicity assessment at each clinic visit and patient reported quality of life (QOL) assessment at 3, 6, 12, 18 and 24 months.
