What is it about?

It is unclear how to deal with low-risk prostate cancer in kidney failure patients being worked-up for a kidney transplant. We developed a model simulating the clinical course of thousands of such patients and investigated several management strategies [definitive treatment (surgery or radiation therapy) and listing after a waiting period of 2 years, definitive treatment and immediate listing, active surveillance and listing after a waiting period of 2 years, and active surveillance and immediate listing] to identify the best strategy from an integrative healthcare perspective. Our study suggests that active surveillance and immediate listing yields the highest amount of quality-adjusted life years.

Why is it important?

It is a general rule in transplantation medicine that every active malignancy is an absolute contraindication for transplantation. This rule is challenged by active surveillance-eligible prostate cancer as these patients do formally not require definitive treatment (i.e. surgery/radiation therapy). As a result, interdisciplinary treatment teams caring for these patients therefore often face the challenge of balancing the benefits of early kidney transplantation and the risk of metastatic progression. Our study suggests that active surveillance and immediate listing yields the highest amount of quality-adjusted life years and therefore supports the decision-making in interdisciplinary transplantation boards.

Perspectives

This research project is a typical example of interdisciplinary research originating from day-to-day clinical activities. We faced the above-mentioned clinical dilemma several times at our institution and at a certain point we decided to translate it into a research question that can be addressed by decision analysis. The resulting simulation model gave us valuable insights into the clinical problem that can improve decision-making at interdisciplinary transplantation boards. It is highly satisfying to feed the resulting insights back to our peers. We are very thankful to the Clinical Journal of the American Society of Nephrology (CJASN) for providing such an efficient knowledge translation platform.
