Partial Volume High-Dose Irradiation in Renal Cell Carcinoma for Intra-TUmoural Control ALongside Current Management

HYPOTHESIS The investigators hypothesise that it is feasible to recruit to a study of localised and metastatic renal cell carcinoma comparing a high-dose short fractionation radiotherapy regime (30Gy in 5 fractions in alternate day fractions over 2 weeks) in comparison to the standard palliative dose-fractionation (30Gy in 10 fractions in daily fractions over 2 weeks). AIMS Primary aim • To demonstrate feasibility of a randomised study comparing high-dose hypofractionated radiotherapy versus standard palliative dose radiotherapy in localised or metastatic renal cell carcinoma Secondary aim * To report acute and late toxicity in both treatment groups * To demonstrate completion of quality of life (QOL) validated EORTC forms by patients under study STUDY DESIGN * Randomised 1:1 * The study is unblinded for the trial investigators and participants. VISITS (in line with routine standard care): * 1 Pre-treatment appointment * 1 CT planning scan (immobilisation/mould room as required dependent on anatomical site) * 10 radiotherapy treatment appointments (Control Arm) / 5 radiotherapy treatment appointments (Experimental Arm) * 2 on-treat clinic reviews (week 1 and week 2) * End of Treatment/Safety follow up (4 weeks post-radiotherapy) * Follow-up at 3 months, 6 months, and 12 months INVESTIGATIONS * Quality of Life questionnaires * Blood tests * Clinical/Physical Examination
