Interviewer: It used to be 50. Now it's 45 and there's a good reason for that. Huntsman Cancer Institute and University of Utah Health says more lives can be saved if men and women who are at average risk of colorectal cancer get screened at 45 instead of 50 years old. Dr. Priyanka Kanth is from Huntsman Cancer Institute. Why the change? What happened?

Dr. Kanth: Over the years since mid-'90s to early 2000, we have noticed an increased risk, increase incidence, and mortality. Actually both. So increased cases and people dying from colorectal cancer. And that was the main reason people started looking into it, researchers started looking into it and came up with this studies, modeling studies. And that's why this recommendation was changed.

Interviewer: Yeah. And the reason that's so important is because unlike other disease that perhaps might show symptoms, and then you would go get treatment. That's not how colorectal cancer presents. It really is screening is the best way to save lives.

Dr. Kanth: Absolutely. You're very right about it. So most of the early onset cancers or any colorectal cancer, early stages do not produce symptoms. Polyp usually starts with a polyp, which is a little bump in the colon and it changes into colon cancer. These polyps do not produce symptoms and they grow slowly, and you will never know you have one. So that's the biggest problem with colorectal cancer. And by the time you have symptoms, it's fairly late. So screening is the best strategy to prevent this cancer.

Interviewer: And this new research has just really shown that people between 45 and 49 because catching it early is the best defense that a lot of good can be done by having it at 45.

Dr. Kanth: Absolutely. Absolutely. There are certain research which has shown that there was a drastic increase even between age 49 and 50. So one study showed that there was an increase of almost 46% between age 49 and 50. So if we decrease it from 50 to 45, we are really hoping to capture that colon cancer patient. And this would be very, very beneficial between that age group.

The other thing I would like to say that this is also an incentive, an added benefit to increase screening from age 50 to 55, 50 to 54. But traditionally, it has been on the lower side if you do it from 50 to 75. There's slightly decreased screening rates in screening uptake between age 50 to 55. So this will help patients who are thinking about it at age 50, but did not get it till age 55. Now they're like, "Oh, you have to get it done at 45, let's get it one at by age 48." Something like that. So this will be very helpful at that point.

Interviewer: Is there a perception that colorectal cancer is an older person's disease?

Dr. Kanth: Yes. I think a lot of us, a lot of our patients in general public we think cancer is an old person's disease, especially colorectal cancer. That's not the case anymore. This is still true. Most colorectal cancer will still be diagnosed when you're older, but there has been a rise in patients who are younger than age 50. Some of it is because of genetic causes, but the rise has been in the average risk. So this perception should be changed. We should consider 45 as new 50 to start screening now.

Interviewer: And really that number, age 45 is the most important number. It's not do I have a family history? It's not do I have symptoms? It's not am I a man or a woman and think I'm less likely to get it. Really as soon as anyone hits that age of average risk of 45, that's the trigger you should go get it checked.

Dr. Kanth: Absolutely. Very correct. So 50 was . . . the same recommendation was for anyone, any gender, male, female. Any person who hits 50, you should get a colonoscopy. Now that has changed to 45. So it doesn't matter if you have symptoms, you should get it checked, especially if you don't have family history. If you have family history, that's a different story. If you don't have family history or average risk, please go get checked at age 45.

Interviewer: How is this going to impact those that do have an increased risk? Not an average risk, an increased risk? Does that also drop their age that they should go in down or do we know?

Dr. Kanth: So, at this point, if you have a family history, we usually start screening early. Most of the time we start screening at age 40. Or if somebody had colon cancer, I'd say whatever age, 10 years before they had colon cancer. So that may not change so much. It's possible we can look at the data and that may change again, but at this point, this recommendation is only for average risk. So family history is a different cohort of patients. That is still a very good point for primary care physician for all of us to ask that history from patients, "Do you have a family history of colon cancer?" Because your risk might be very different from the average risk.

Interviewer: So have that conversation if you're above average risk with your physician, your provider is whether or not you should get it earlier.

Dr. Kanth: Absolutely. Yes.

Interviewer: All right. And for the recommendation, is a colonoscopy okay? The home stool test, is that impacted by this age going down to 45?

Dr. Kanth: The best screening is the one that gets done. So that's another message which has to be delivered by providers. Colonoscopy is not the only screening test. Colonoscopy is gold standard because you can see the polyps you can remove it before it turn into cancer. But there are other very, very good stool tests which can detect colon cancer easily. They are non-invasive, you stay at home, you don't have any logistics around it. And those are good tests to be done. So that's a big message which everyone should know that colonoscopy is not the only way to detect cancer. There are other very good stool tests, which everyone should consider. If you're declining colonoscopy for any reason, do go for a stool test.

Interviewer: So if it's a stool test or if it's the colonoscopy, it doesn't matter. Average risk needs to be 45 now.

Dr. Kanth: Absolutely.

Interviewer: All right. And also, I understand with the new recommendation that Medicare, Medicaid, and also your commercial insurance will cover either one of those screenings starting at 45.

Dr. Kanth: That is correct. And that's what we believe after the new recommendation which has been endorsed by pretty much all the societies that all these should be now covered under preventive care just that how we had it at age 50. Even now, some insurances are already covering at age 45, but that was more sporadic. So now we expect this to be 100% covered.

Dr. Tom Miller: Screening for prostate cancer.

Dr. Blake Hamilton: Oh my.

Dr. Tom Miller: Why the oh my?

Dr. Blake Hamilton: This is a very controversial subject.

Dr. Tom Miller: This is Dr. Tom Miller. We are going to be talking about prostate cancer screening next on The Scope.

Announcer: Medical news and research from University of Utah physicians and specialists you can use for a happier and healthier life. You're listening to The Scope.

Dr. Tom Miller: Hi, I'm here with Dr. Blake Hamilton. He's the medical director for the urology clinic, and he's also associate director for the division of urology. Let's talk about it. Is prostate cancer screening with P.S.A. testing something that's time has come and gone?

Dr. Blake Hamilton: No, I don't think so. It's a shifting environment to be sure, but I think it still has relevance.

Dr. Tom Miller: You know, the national guidelines, or a couple of the guidelines out there now say that you really don't need to screen men for prostate cancer using the blood test, the P.S.A., prostate specific antigen test. That's based on a couple of large studies, I believe. The outcomes of those studies, one in Europe, one in the United States, didn't back up the idea that using this test could save lives best that the studies showed.

Dr. Blake Hamilton: We have to go back and understand the history of P.S.A. P.S.A. is a protein that's produced by the prostate. It has a role. It has a function. We learned many years ago, three decades ago, that it goes up in prostate cancer, and when you treat prostate cancer it goes down. It became used as a marker for recurrence of treated prostate cancer. It continues to be very reliable. It's one of the best blood markers that we have for cancer.

Dr. Tom Miller: No question. I think we all know that we find more prostate cancer using this test. The question is does it save lives in the long run.

Dr. Blake Hamilton: The two studies that you refer to, depending on how you interpret them, show that there was not enough difference between the group that was screened and the group that was not screened. There are several problems with those studies. One is that they may not be mature enough. They had an average follow up of eight, nine, ten years, and the arms are separating. If we get to 15 years I think we'll see a difference. I think we'll see a clear separation between those two arms. The other problem is there are some methodological problems in how the patients were accrued. It's complicated. I think the real issue is that some people with prostate cancer will suffer immensely and die, and many will not. What we really need to do is do a better job of trying to predict who needs treatment and who doesn't. I think that what's happened over the last couple of decades is when men are diagnosed with prostate cancer based on P.S.A. screening they automatically have gotten treatment. So, in a sense as a community we've over-treated men with prostate cancer.

Dr. Tom Miller: I think part of the concern is also the potential complications of the surgery or the other treatments available for prostate cancer. I mean it's not a benign procedure, and there are outcomes that are difficult for the patient. I think that is coloring the judgment of some of the task force groups that are looking at screening guidelines currently.

Dr. Blake Hamilton: The problem is you still have some 250,000 men who will be diagnosed with prostate cancer this year in the United States. There will be some 35,000 of those who will die from prostate cancer. To say that prostate cancer screening with P.S.A. has come and gone would be throwing the baby out with the bathwater. What we need to do is keep the screening but make better decisions about when to biopsy and when to treat prostate cancer. Already we're seeing a significant decline in the number of men who are being treated, and that's appropriate. But, we've got to keep looking for the ones that are going to be lethal cancers, because they're real.

Dr. Tom Miller: Let's talk practicalities. Are you saying that we should continue to follow the past guidelines which say begin screening in men at the age of 50, and then continue screening every year with P.S.A. testing?

Dr. Blake Hamilton: There are now many alternatives to that.

Dr. Tom Miller: Right.

Dr. Blake Hamilton: One alternative, which comes from the U.S. preventive services task force, is to not screen at all. The American Urological Association has modified their guidelines to suggest that we screen maybe not every year but every two years in men between the ages of 55 and 70 where we think that we'll find the highest yield in the patients for whom it will really matter. Screening in 80 year olds, not important. Screening in the younger generation, not enough data to show evidence that it helps or makes a difference.

Dr. Tom Miller: Younger generation meaning 50 years old and above?

Dr. Blake Hamilton: Less than 55.

Dr. Tom Miller: Less than 55.

Dr. Blake Hamilton: Although there are many researchers who would argue that between 45 and 55 should be included. The guidelines as we have them now would be that those men in that 15 year window, and screening not as intensely as we have in the past, but not to give it up.

Dr. Tom Miller: Let's say that your P.S.A. is elevated. What should the patient do? Should they go then to a urologist who specializes in prostate cancer? A lot of this, as you say, is going to depend on the expertise of the specialist taking care of this type of problem.

Dr. Blake Hamilton: I think most urologists have the ability to evaluate an elevated P.S.A. and make a decision on a biopsy. There continue to be a variety of opinions out there. If you have a single elevation in the P.S.A. I think it's reasonable to wait some time and repeat it and think about what that means.

Dr. Tom Miller: So, screening is something that you believe we should continue. You think it's a good idea.

Dr. Blake Hamilton: Yes, I think we should continue screening but do it judiciously and appropriately, and then think carefully without automatic treatment of those who are diagnosed with prostate cancer.

Dr. Tom Miller: A final thought. What about that time honored rectal exam? Do we still have to do that on patients? It's the brunt of so many jokes.

Dr. Blake Hamilton: Yes, it is. Unfortunately, there are some bad prostate cancers that have low P.S.A.s and are only found on physical examination, so we're going to continue doing that exam, Tom.
