GU Cancers 2026 | Future research trends in platelet polygenic risk scores in RCC

Mustafa Saleh, MD, Dana-Farber Cancer Institute, Boston, MA, discusses the next steps for his research on germline platelet polygenic risk scores predict survival in renal cell carcinoma (RCC). Further research is needed to understand the biology behind the polygenic risk score association with survival, and this score may potentially be used as a tool in the clinic to stratify patients and improve the accuracy of predicting survival and response. This interview took place at the 2026 ASCO GU Cancers Symposium in San Francisco, CA.

So for the first question, our next steps are, first of all, replicating our study in independent cohorts. It would have been better if it was in clinical trials, and we’re on the way to do that. Second thing is to look at this polygenic risk of platelets in other outcomes, for example, response to therapy and recurrence. And we’re also on the way to do that...

So for the first question, our next steps are, first of all, replicating our study in independent cohorts. It would have been better if it was in clinical trials, and we’re on the way to do that. Second thing is to look at this polygenic risk of platelets in other outcomes, for example, response to therapy and recurrence. And we’re also on the way to do that. Another thing that will also make this study impactful is to actually see what’s the biology behind this polygenic risk score association with survival. Although it does make sense that platelet biology is associated with worse prognosis and survival, but we’re also interested to see if actually the biology – what’s the actual biology behind it. As for stratifying patients based on this score, probably when we’re able to replicate the score and try to see in nomograms and in composite scores with other biomarkers, how it would improve the accuracy of predicting survival and response, we would be able to use this as a potential tool in the clinic’s future, in the future.
