Sherea Cary: 

What differences do you see in terms of aggressiveness for cancers in different…various populations? 

Dr. Nyame: 

This is an area of research that for me, is trying to understand why certain populations have more aggressive or worse outcomes when it comes to prostate cancer. 

The most obvious example of this here in the United States is for Black men. Black men are more likely to be diagnosed with prostate cancer each year, so about 70 percent more likely to be diagnosed, and they are twice as likely to die from prostate cancer as men of other races in the United States. If you look at what the natural history of prostate cancer and Black men looks like, meaning if you were to chart from diagnosis through the course of the disease, does it look different for Black men? The answer is yes, it appears of Black men get prostate cancer when they’re younger, and there’s data to suggest that perhaps Black men get more aggressive prostate cancer because they’re more likely to progress from the localized or treatable disease to stage IV aggressive disease that can’t be treated. We don’t understand what the drivers of that are for a long time, the medical community has suggested that it’s all biology, and by that may be an inherited biology, but we know that health disparities really carry a significant social contribution. And, in fact, I like to say that social and environmental factors inform biology too. And so, if we see something biologic that explains these trends, it doesn’t mean that that’s the way they were born, it might mean that you put someone in a community that lives near a highway with high pollution or does not have access to clean water or lives in a state of high stress or over security. We don’t know what the biologic manifestations of those types of experiences are, but that perhaps is the reason why we see our communities of color, especially our Black men, are experiencing a higher burden of prostate cancer. 

Sherea Cary: 

So, is there a push to have African American men tested earlier with the PSA test, since it appears that they may get prostate cancer earlier?  

Dr. Nyame: 

The U.S. Preventative Services Task Force, which makes a recommendation to the medical community about prostate cancer screening states that they cannot make a specific recommendation about screening in Black men and other high-risk populations like men with a strong family history of prostate cancer, because those men were not included in the clinical trials that have looked at the efficacy of PSA testing for screening. 

Unfortunately, Black men make up 3 percent or less of participants in the two screening trials that have informed whether there’s a benefit to PSA testing, which there has been shown to be a 20 percent decrease in dying from prostate cancer if you get screened. We recently took data from the screening trials and superimposed them on real-world data from our surveillance apparatus for cancer in the United States, and what we found was that if you did lower the age of screening in Black men from age 55 to 45, that you did decrease the risk of dying from prostate cancer significantly. It is our hope that this type of research will encourage the U.S. Preventative Services Task Force and other medical societies to reconsider their screening recommendation for Black men, ultimately, whatever, if there is a recommendation made to screen at younger ages, I think we need to be conscientious and evaluate what the impact is on the ground, so that if there is a time where we need to reverse a recommendation like that because it’s potentially harmful, that we consider that. But I feel strongly sitting here today that we do need to advocate for earlier screening and Black men.

Can prostate cancer early screening be effective? Watch as expert Dr. Yaw Nyamefrom the University of Washington shares information about those who are at higher risk of prostate cancer and recommended ages to start screening in these higher-risk groups for proactive care.

Sherea Cary: 

What screening test or risk-reducing care would you suggest for men who have a family history of prostate cancer, and at what age should screening begin for specific populations? 

Dr. Nyame: 

Unfortunately, there is no data, rigorous data to help answer this question, but we know that men that have a high risk of developing prostate cancer benefit from earlier testing with PSA. We know this from a variety of studies, including some modeling studies, which we have done here at the Fred Hutch Cancer Center at the University of Washington. When I talk about high-risk groups, it really falls into two categories, men who have a strong family history and a strong family history means a first-degree relative, father, brother, grandfather that has prostate cancer. 

But when we look at the genetics of prostate cancer it’s not just about prostate cancer itself, what we have found is that things that lead to family histories of breast cancer, ovarian cancer, colon cancer also increase your risk of prostate cancer, for instance, the BRCA gene, which is a breast cancer gene is associated with a marked increased risk of prostate cancer. So, knowing your family history matters and knowing it beyond prostate cancer is important. The other high-risk group as men of African descent or ancestry, we know our Black men have a much higher risk of developing prostate cancer in their lifetime, it’s about a one in six or one in seven risk compared to one in nine in the general population. So, the recommendation I make for these two groups is to consider screening earlier and to do it more frequently. On average, PSA screening happens for men between the ages of 55 and 70 or 74, and it’s usually every two years, if you look at the population level data, I would suggest that you consider screening at age 45 or 40 and doing it every year, however, you’ve got to turn the screening off at some point. So, if your PSA stays low and is non-concerning into your early 70s, then I think you can be reassured that your risk of having a fatal or aggressive cancer is low, and you could safely stop screening. 

Sherea Cary: 

So for someone who has a first-degree relative such as a father who had prostate cancer and maybe even an aggressive form of prostate cancer, it will be important for them to get screened at 40 to start at least having a baseline number to be able to watch it?  

Dr. Nyame:

Absolutely. The baseline number is really a topic of discussion in the urologic community because we know that if you get a PSA at age 40 and it’s above one or above the median for your age group, that you’re at a lifetime risk of having what we call significant cancer, so that’s a cancer that might have the potential to be fatal in your lifetime is higher. And so theoretically, you could get that one-time PSA at 40 and use that as a basis for how intense your screening practice would be. I’ve talked about PSA testing, but screening also involves the digital rectal exam, and it’s important that men understand that both those things together is what leads to a thorough and good clinical evaluation, when it comes to prostate cancer risk.
