Do Your Coffee Genes Affect Prostate Cancer Survival?
Could how your body processes caffeine change what coffee means for prostate cancer survival? A large multicenter study found a hint: higher coffee intake tracked with better prostate cancer survival mainly in men with a particular caffeine-metabolism gene. Here is the careful read, limitations included.
In this video, board-certified nephrologist Dr. Sean Hashmi walks through the study design, the fast-versus-slow caffeine metabolism gene, what the results showed by disease stage and genotype, and why this is an early signal that needs replication.

(In 5,727 men, higher coffee intake was not significantly associated with overall or prostate cancer-specific survival across the whole group. In men with localized disease and in those carrying the CYP1A2 AA genotype, higher intake was associated with longer prostate cancer-specific survival, HR about 0.66-0.67, with a gene-diet interaction. The findings were only nominally significant, subject to confounding, and require replication.)
