Scientific title | A feasibility study for a multicentre randomised controlled trial to compare surgery (partial nephrectomy) with needle ablation techniques (radiofrequency ablation/cryotherapy) for the treatment of people with small renal masses (4cm) |
Study acronym | CONSERVE |
Study objectives | The number of people diagnosed with kidney cancer has doubled over the past 20 years, making it the eight most common cancer in the UK. Most tumours are less than 4cm in size, but over 80% of these are malignant (cancerous) and if left untreated, will slowly grow and spread. Current standard treatment for these small kidney cancers is to remove the diseased part of the kidney in an operation called a partial nephrectomy, but this can be quite a difficult operation. Because of the small tumour size and difficulties with the operation, other treatments have been developed to destroy the tumours. These treatments include radiofrequency ablation, which means that the tumour is destroyed by heat, and cryoablation, which means that the tumour is frozen and destroyed. Although removing the part of the diseased kidney in an operation is the tried and tested way to treat the kidney cancer, it does have risks and complications, such as bleeding. The other two treatments are less intrusive to the patient, and are less complicated as they do not require such a large operation as having part of the kidney removed, but it is not known if they are as good at destroying all of the tumour, and whether or not patients who have their tumour destroyed with these new methods require further treatment in future. In this study, we are trying to determine if a large-scale study comparing these treatments is possible which is why this is called a feasibility study. We are also looking at whether patients would be willing to be randomly assigned to a treatment group. The results of this study will then be compared to see how effective each of the treatments were and whether the number of patients who were happy to be randomly assigned to a treatment could be used to determine the number of patients required in a large-scale trial. |

Intervention | Cryoablation, Participants in this study may be randomised to undergo cryoablation as treatment for their small renal mass; Partial Nephrectomy, Participants in this study may be randomised to undergo a partial nephrectomy as treatment for their small renal mass; Radiofrequency ablation, Participants in this study may be randomised to undergo radiofrequency ablation as treatment for their small renal mass; Follow Up Length: 6 month(s) |
Intervention type | Other |
Primary outcome measure | To estimate the number of patients with a renal mass <4cm who agree to trial randomisation measured at over 18 months of recruitment |
Secondary outcome measures | 1. Evaluation of treatment of tumour by CT scan and biopsy measured at using CT scans at 1, 3 and 6 months after treatment and renal biopsy at 6 months 2. Qualitative interview responses for after treatment for patients who are eligible measured at eight to sixteen weeks after treatment 3. Qualitative interview responses for patients who decline randomisation measured at two to sixteen weeks after recruitment interaction 4. Quality of Life questionnaire reporting differences measured within 14 days of randomisation, and at 3 months and 6 months follow-up |
