Background:
Screening for renal cell carcinoma (RCC) has been identified as a key research priority; however, no randomised control trials have been performed. Value of information analysis can determine whether further research on this topic is of value.
Objective:
To determine (1) whether current evidence suggests that screening is potentially cost-effective and, if so, (2) in which age/sex groups, (3) identify evidence gaps, and (4) estimate the value of further research to close those gaps.
Design, Setting, And Participants:
A decision model was developed evaluating screening in asymptomatic individuals in the UK. A National Health Service perspective was adopted.
Intervention:
A single focused renal ultrasound scan compared with standard of care (no screening).
Outcome Measurements And Statistical Analysis:
Expected lifetime costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER), discounted at 3.5% per annum.
Results And Limitations:
Given a prevalence of RCC of 0.34% (0.18-0.54%), screening 60-yr-old men resulted in an ICER of £18 092/QALY (€22 843/QALY). Given a prevalence of RCC of 0.16% (0.08-0.25%), screening 60-yr-old women resulted in an ICER of £37327/QALY (€47 129/QALY). In the one-way sensitivity analysis, the ICER was <£30000/QALY as long as the prevalence of RCC was ≥0.25% for men and ≥0.2% for women at age 60yr. Given the willingness to pay a threshold of £30000/QALY (€37 878/QALY), the population-expected values of perfect information were £194 million (€244 million) and £97 million (€123 million) for 60-yr-old men and women, respectively. The expected value of perfect parameter information suggests that the prevalence of RCC and stage shift associated with screening are key research priorities.
Conclusions:
Current evidence suggests that one-off screening of 60-yr-old men is potentially cost-effective and that further research into this topic would be of value to society.
Patient Summary:
Economic modelling suggests that screening 60-yr-old men for kidney cancer using ultrasound may be a good use of resources and that further research on this topic should be performed.
