- 0:00The purpose of an MRI in my world, in the Pedro de protocol
- 0:03world, is not so you can get a better target for a biopsy.
- 0:07It's so we can get a good baseline to compare over months
- 0:11and over years. Gleason score passe unnecessary
- 0:16dangerous. Why?
- 0:17Because the number scares men into doing things that harm
- 0:21their health irreversibly in some cases.
- 0:24Really want to trust that? I don't think so.
- 0:28The trust comes from an experience and an observation
- 0:31that requires time, which requires patience, which
- 0:35requires temperance. The standard of care regarding
- 0:41prostate cancer must change. What we're doing right now is
- 0:47not good enough, and you're going to change it, and I'm
- 0:50going to help you change it. Today we're going to focus on
- 0:54imaging. How should you have your
- 0:57prostate gland evaluated? What is the best use of an MRI?
- 1:02How can you direct your physician to do it?
- 1:05The way that makes the most sense?
- 1:08Now, the reason they do it, the way they do it, we'll talk about
- 1:11that is because that's how they do it.
- 1:14They are in the rhythm, it is efficient.
- 1:19They know what to do MRI with contrast, standard of care,
- 1:24right? It's not the best care.
- 1:26It's just what they're used to doing.
- 1:29And the minute you step out of line, you're only the guy at the
- 1:32convenience store who breaks out his wallet and pays in cash
- 1:36instead of swiping the card. Everybody behind you in the line
- 1:40gets annoyed. You're the guy that's saying,
- 1:42listen, I want to buy parametric MRI without contrast and they
- 1:48look at you like you have two heads saying, well, we've never
- 1:50heard of that, or we don't do that, or that's not going to
- 1:54tell us what we need. Nonsense.
- 1:57It is the cutting edge. It is the best way to use the
- 2:01MRI. So we're talk about other means
- 2:04of looking at the anatomy. Why is that important?
- 2:08Because that's one of the ways you get rid of the prostate
- 2:11biopsy. Can we just stop poking trocars
- 2:16into a prostate that's already a little bit angry?
- 2:20It's probably already a little bit inflamed.
- 2:23And if it has cancer in it, you're going to spread that
- 2:26cancer. Very high risk, in my opinion.
- 2:31Now they'll tell you there's no evidence showing that it spreads
- 2:35cancer. They never looked.
- 2:38They never did a study, Zippo, never in 50 years.
- 2:44Why not? Well, the ethic of it is
- 2:47challenging and there's no motivation.
- 2:50Who wins if they do a study and it shows there's actual
- 2:54increased risk of metastatic spread.
- 2:56Now the studies are out there in regard to other biopsies, breast
- 3:01tissue. There are even studies, case
- 3:03studies and case reports showing spread.
- 3:06So no biopsy. Instead, we do the MRI and we do
- 3:10it not so we can figure out where to stick the needle.
- 3:14That's another just illogical, biologically implausible
- 3:18concept. The idea that you're going to do
- 3:21an MRI, right, so you can identify where to stick the
- 3:24needle, as if prostate cancer clusters into tiny little
- 3:29packages just waiting to be biopsied.
- 3:33That's dumb. It doesn't behave that way.
- 3:37Imagine that you had an infestation of cockroaches and
- 3:41you want to get rid of them. You leave two behind.
- 3:45You haven't solved the problem, have you?
- 3:47They're coming back. The same is true for prostate
- 3:50cancer. You stick the needle in, you do
- 3:53a local ablation. Maybe it reduces the volume of
- 3:56the disease. That's not a bad thing, but it's
- 3:59not going to cure anything, ever, because there are less
- 4:02cells left behind. That's why we do what we do,
- 4:06systemic therapy. The repurposed drugs have a
- 4:11carpet bombing effect. They have an impact on the
- 4:15entire body. One of the ways we follow that,
- 4:18yes, we use the PSA, the prostate specific antigen.
- 4:22It's a helpful test if properly interpreted.
- 4:25You need to look at it at appropriate intervals.
- 4:28You need to not overreact if it's too high or too low because
- 4:30there are a lot of things that affect it.
- 4:32There's something called intra testing variability.
- 4:36If I took the same blood specimen and test it on the same
- 4:40day with the same reagent, I can get a difference in PSA of up to
- 4:4510, maybe 15%. Same blood sample, same test.
- 4:52So if you see a change in your PSA from one test to the next,
- 4:56the first thing to do is to take a deep breath and interpret it
- 5:01over time. Where's the change going?
- 5:03What's the trend? So intra test variability
- 5:06applies to the MRI as well. An MRI is not concrete evidence
- 5:12of anything. It's information that needs to
- 5:15be interpreted. The MRI itself is subjective.
- 5:20The radiologist looks at it, says I think that is a pyrid's
- 5:24A4. The next one may look at it and
- 5:26say I think it's a three. A third one may say I think it's
- 5:29a 5 S the pyrid's number. It sounds concrete, but it's
- 5:34subjective and the same image can be interpreted differently.
- 5:39The point is not that the images are invalid, it's that they need
- 5:44to be carefully understood. Your doctor, your nurse
- 5:48practitioner, needs to have a fund of knowledge like mine so
- 5:52you can interpret these things in the context of the disease
- 5:56and the global health. So let's go to that MRI.
- 5:59You ordered the MRI. They do it with a gadolinium
- 6:01contrast. Absolutely, 100% unneeded and
- 6:06harmful. Now people argue about whether
- 6:09or not it's harmful. Gadolinium is a heavy metal
- 6:11folks, does not belong in the human body.
- 6:15It gets filtered through the kidney.
- 6:17Now healthy kidneys can handle that, we think.
- 6:21But how about if you're going to use it for monitoring?
- 6:23Well, that means you're going to do this MRI more than once.
- 6:27And every time you do it, a little more gadolinium
- 6:30accumulates and it accumulates in the brain.
- 6:34Now I can think of no value, no purpose, no health enhancing
- 6:39attribute of dropping heavy metal in the brain, right?
- 6:43So they have to prove to us that it's going to be good for you.
- 6:47They can't. The best they could say is,
- 6:49well, we don't think it's going to hurt you, but if you get a
- 6:53little demented in 10 years, let us know.
- 6:57Too late. So if it was critical, I would
- 7:01say, you know, maybe we have to suffer the risk, but we don't
- 7:05just because they're trying to jam it down your throat.
- 7:08And I've ordered many Mr. is for prostate and frequently there's
- 7:12push back. We can't do this.
- 7:15It has to be with contrast nonsense.
- 7:18The MRI, there's a bi parametric means of doing this study.
- 7:23The traditional method is called multi parametric that requires
- 7:28the dye so they can do some of their metrics that they like to
- 7:32do. Picture looks better.
- 7:35They can get some measurements that cannot otherwise be
- 7:37obtained but are not important to us to discern what's
- 7:41happening with regard to prostate nodules and the
- 7:45potential of cancer being present.
- 7:47The multi parametric with contrast is passe.
- 7:52It doesn't know it yet but it's day has gone.
- 7:57The biparametric is king of the hill, and this is cutting edge
- 8:01research. The research backs up what I'm
- 8:04saying. The biparimetric studies are
- 8:08shorter in duration and take 15, maybe 20 minutes.
- 8:11There's no contrast and you can gain the same quality imaging
- 8:16that lets us determine the level of your prostate cancer and
- 8:20perhaps most importantly, a basis of comparison.
- 8:24Oh, by the way, it's less expensive.
- 8:27So let's review by parametric. Remember that word?
- 8:31That's what you're going to request.
- 8:33By parametric. Less expensive, faster no die
- 8:39when there's. Look, when years ago I was
- 8:41moonlighting and I had a job and my job was to sit in the
- 8:45radiology suite whenever they were doing intravenous die.
- 8:49Why? Because bad things can happen.
- 8:52And I was there to resuscitate, to treat in the event there was
- 8:55an allergic reaction. Well, guess what?
- 8:58If you don't put a dye in, you can't get an allergic reaction.
- 9:01Nothing bad can happen by avoiding it.
- 9:03You, my friends, you must be assertive.
- 9:07Decline the the contrast. Tell them it'll cause harm.
- 9:10I'm not doing it. Your doctor will back you up.
- 9:14And if your doctor doesn't back you up, you may want to
- 9:17reconsider that relationship. It's in your best interest to
- 9:21not get dye. Now suppose you have a hip
- 9:25implant and you can't do an MRI. Plane X-rays aren't worth doing.
- 9:32CAT scans have too much risk for this purpose.
- 9:34Radiation, right? They can do micro ultrasounds
- 9:39and there are some urologists who have high skill with the
- 9:43ultrasound and they can do a great analysis of the prostate
- 9:49without the MRI. Now I don't recommend this if
- 9:51you can otherwise get the MRI. I like an MRI better.
- 9:55Part of the reason I like the MRI better is because you're not
- 9:58going to have to listen to the urologist tell you how you need
- 10:01a biopsy or else you're going to die.
- 10:04Some of them are like that or that they'll do the ultrasound
- 10:08if you would acquiesce to letting them do a targeted
- 10:13biopsy. It sounds elegant, doesn't it?
- 10:16A targeted biopsy? No, it's dumb.
- 10:21It is illogical. You're imagining that you can
- 10:25identify the cancer in a manner that makes a difference.
- 10:29Ironically, by targeting it, by getting it more likely to the
- 10:33most dense portion of the cancer, you could well be making
- 10:37things that much worse. So the micro ultrasound is an
- 10:42option to consider, absent the biopsy.
- 10:46Now there are many urologists out there that are really
- 10:50processing what they're doing, and they're starting to
- 10:53reconsider the biopsy frenzy. They're not there yet.
- 10:58It's going to be another 15 years.
- 11:01I think you really need a whole generation of doctors.
- 11:06I hate to say it this way, guys, but they got to get their ROI
- 11:10before they can get out of the game, right?
- 11:12Or turn on investment. If you're JoJo the doc and 30%
- 11:16of your income is coming from biopsies, you don't want that to
- 11:20go away too quickly. I was at a a urology conference
- 11:24recently talking about updates and conventional treatment.
- 11:27It's my responsibility to you that I stay up to date with
- 11:31conventional therapy just in case there's something out there
- 11:36therapeutically worthwhile. And you know what?
- 11:39There are some things that are of interest to me as your leader
- 11:43in functional, the petroty protocol.
- 11:46There's some things of interest. We'll talk about them in podcast
- 11:48to come. In fact, this MRI information
- 11:52comes from that conference as well.
- 11:54But in the back of the room, one of the gentlemen got up on the
- 11:57microphone. Doctor, he was talking about
- 12:00immunologic treatment someday, obliterating the need for cancer
- 12:05surgery and getting rid of the need for radiation.
- 12:08So they're looking at that research space.
- 12:11Not there yet. In the back of the room, a
- 12:14Doctor Who makes his living cutting out prostate says woof,
- 12:17I hope we doesn't come to the market for another two or three
- 12:20years. Had to hit his retirement
- 12:22threshold. There's a human variable in all
- 12:27endeavors in medicine. It's not wrong, it's not
- 12:31unethical, It is just unavoidable.
- 12:35And if you're aware of that human element of the
- 12:39self-interest woven into it, that can color recommendations.
- 12:44Another interesting study was looking at the recommendations
- 12:48that come from different doctors and what patients chose to do.
- 12:51It's not surprising that if the consultation occurred with a
- 12:55surgeon, the majority of men had surgery.
- 12:59If it came from a radiation oncologist, the majority of men
- 13:04had radiation therapy. If it comes from me, from the
- 13:08Pederuti protocol doctors and they're going to be more of us,
- 13:10we're reproducing out there. If it comes from me, I like to
- 13:14believe a majority of men are going to say no to both.
- 13:18It's OK guys, if you had radiation, it's OK if you had
- 13:21your prostate removed. We're here to support your
- 13:24vitality, to give you choices and options.
- 13:27And this MRI is a critical step in the process.
- 13:32The purpose of an MRI in my world, in the in the Pedro de
- 13:35protocol world is not so you can get a better target for a
- 13:38biopsy. It's so we can get a good
- 13:41baseline to compare over months and over years.
- 13:45How do we know if you have an aggressive cancer?
- 13:48We check it over time. Gleason score passe unnecessary,
- 13:54dangerous. Why?
- 13:56Because the number scares men into doing things that harm
- 14:00their health irreversibly in some cases.
- 14:03And oh, by the way, the Gleason score is another subjective.
- 14:07I think it's an 8. I think it's a seven.
- 14:10Really want to trust that. I don't think so.
- 14:14The trust comes from an experience and an observation
- 14:17that requires time, which requires patience, which
- 14:21requires temperance so you don't get excited and nervous.
- 14:26Oh my God, I have prostate cancer, I'm going to die, and
- 14:29you have the cloud following you.
- 14:32So remember, biparametric MRI, no CAT scans, micro ultrasound
- 14:40is an option if you have a hip replacement or otherwise cannot
- 14:43do an MRI. If you're a little
- 14:45claustrophobic and you get anxious, that biparametric study
- 14:50is much more brief and we have drugs for that.
- 14:54An anxiolytic is totally legit to use before you go in that
- 14:58machine. So imaging the prostate is
- 15:01essential. Whether you're going to do
- 15:04conventional treatment or you're going to do a Petri protocol,
- 15:08the imaging is essential. Do not proceed based on APSA and
- 15:13a digital rectal exam alone. You need to insist on the MRI if
- 15:19they're not offering it, and it needs to be done with what's
- 15:22called the biparametric protocol.
- 15:25Same equipment, biparametric, and you want to look for a 3T.
- 15:31That's T as in Tango MRI. They're the state-of-the-art.
- 15:35They're the best, the best imager.
- 15:38There's something called a 1.5 T that was an earlier generation
- 15:42of MRI. They're still out there, and you
- 15:44will not know which kind of equipment you're being subjected
- 15:48to unless you ask. I want a 3T by parametric MRI.
- 15:54Yikes. Now you sound like an educated
- 15:57guy. All right, folks, I hope this
- 15:59was helpful to you. Stay healthy, Don't let them
- 16:02push you. Get your information and then
- 16:06craft a path that you feel confident with.
- 16:09Keep fighting cancer like a man. We're born to live.
- 16:12We're not born to wither. All right, guys, talk to you
- 16:14next time. Bye.
