Transcript
- 0:00Scott Webb: Today I'm joined by Dr.
- 0:01Ien Rupp, colorectal surgeon with Prisma Health, and she's
- 0:04here to discuss colorectal cancer detection treatment and hope.
- 0:11Scott Webb (Host): This is Flourish, the podcast brought to you by Prisma Health.
- 0:14I'm Scott Webb.
- 0:15Scott Webb: Doctor, it's nice to have your time today.
- 0:17We're gonna talk, colorectal cancer detection, treatment, and hope most
- 0:22importantly, before we get there though, what does it mean if we
- 0:25find a polyp during a colonoscopy?
- 0:26And is that the same thing as a tumor?
- 0:29Dr. Irena Rupp:
- 0:29a polyp is an abnormal growth in the colon, but when we look
- 0:33at it And we remove it during colonoscopy, vast majority of these
- 0:36are going to not, be a cancer.
- 0:39A good portion of them will be a type of tissue that can eventually
- 0:42evolve into a cancer, given enough time And the right environment.
- 0:46The vast majority of them are not a cancer.
- 0:49In fact, of all the screening colonoscopies we do, we find
- 0:52a cancer 1% of the time.
- 0:54So.
- 0:55Polyps are actually quite common.
- 0:57We find polyps on about 50% of vocal colonoscopies that we do.
- 1:01And of those, a good portion will be pre-cancerous, isn't have a potential
- 1:06to develop into a cancer, but we either remove them or they potentially n
- 1:10necessarily progress to that stage.
- 1:12Scott Webb: for sure.
- 1:13Dr. Irena Rupp:
- 1:13Tumor on the other hand, generally implies that there is a large, mass.
- 1:17So can it be a polyp?
- 1:18It can be a polyp, but kind of a very, very large one where just taking it out
- 1:23with, a colonoscopy, is not necessarily, always of an option due to sheer size.
- 1:30The tumor can be synonymous with a very large polyp.
- 1:33It can also be synonymous with cancer.
- 1:35Scott Webb: Okay.
- 1:36Yeah, and I think you kind of covered this, but I wanted to
- 1:38make sure we underscore this.
- 1:40How often is colon cancer found during a regular screening?
- 1:43Dr. Irena Rupp:
- 1:43Less than 1% of the time providing that the screening is true screening
- 1:48exam, And the patient is asymptomatic.
- 1:50So we're not having abdominal pain, we're not having bleeding.
- 1:53We don't have any major family history that put its elevated risk, no bowel habit
- 1:58changes, and no positive fit or Cologuard test that led to the colonoscopy.
- 2:02If any of those preexisting conditions are there, the chance of there being
- 2:06something found, either a polyp or an actual cancer is gonna be
- 2:10higher, but again, very, very low.
- 2:12Scott Webb: low.
- 2:13Very low.
- 2:13Yeah.
- 2:14So then what happens, doctor, if colon cancer is found?
- 2:17Dr. Irena Rupp:
- 2:17So then, the first thing that happens is identification and biopsy.
- 2:22Colon cancer is the most common cancer to happen in colon, but it's not the
- 2:26only one, so it's very, very important.
- 2:29When we diagnose, you know, a mass that looks like a cancer And the
- 2:32colon that we biopsied and confirm that it's actually colon cancer.
- 2:35There are several other types such as neuroendocrine tumors, GSTs
- 2:39and rest, sarcomas and lymphomas.
- 2:41That can also happen in the colon, And the treatment for
- 2:43them is going to be different.
- 2:45The second thing that happens once we confirm that This is true colon cancer,
- 2:50is staging and staging to be simply put.
- 2:53How far along is this?
- 2:55, And it uses several radiology modalities.
- 2:58Most commonly a CT scan of the chest, abdomen, pelvis to determine has the
- 3:03tumor really just stayed in the colon or has it gone to any other organs, which
- 3:06again, guide our treatment and management.
- 3:09So once we get the staging accomplished, then we can talk
- 3:12about the plan of treatment.
- 3:14The tumors confined to the colon and has not spread anywhere else than the main,
- 3:18upfront treatment for That is surgery.
- 3:21Scott Webb: wondering, doctor, about the stages of cancer.
- 3:23I hear about stages when it comes to any kind of cancer.
- 3:25Are there different stages for colon cancer and if so, how is the staging done?
- 3:29Dr. Irena Rupp:
- 3:29So staging, for colon cancer upfront at diagnosis is
- 3:34With the CT scan to make sure that it is not, an advanced disease.
- 3:37So we are ruling out.
- 3:38Stage four disease, which would mean the tumor might have gone
- 3:42to other organs and therefore the treatment upfront may not be surgery.
- 3:47If That is not the case, then we are up against either stage one, two, or three.
- 3:52The difference between stage one and two is the depth of invasion
- 3:55of the tumor into the colon wall.
- 3:58And stage three generally means the tumor has gone to lymph nodes, so
- 4:02tissue that carries, lymph away from the colon and into the central circulation.
- 4:07All of those tumors, stage one, two, and three get staged actually after surgery,
- 4:12after we excise it, And the pathologist is able to evaluate the tumor depth
- 4:16of invasion as well as lymph nodes.
- 4:18Scott Webb: sure, yeah.
- 4:21And I'm sure there's a range here, as you say, there's different stages,
- 4:24obviously, but generally speaking, and maybe broadly speaking, doctor,
- 4:27how is colon cancer typically treated?
- 4:30Dr. Irena Rupp:
- 4:30If we are catching it in a process where it has not spread to other
- 4:33organs, the upfront treatment of colon cancer is typically surgery.
- 4:37Surgical resection of the tumor.
- 4:39That will allow us to then specifically determine the stage
- 4:43and design any further treatments that may or may not be necessary.
- 4:47We also evaluate molecular markers of the tumor, so the kind of chemicals the tumor
- 4:51produces that make it more susceptible to certain medications versus other's.
- 4:56Colon cancer believe and now is about 20 different diseases, if not more.
- 4:59So it's actually very important for us to know some of those molecular profile
- 5:03of the tumor to guide for the treatment.
- 5:05Scott Webb: Yeah.
- 5:05Wondering, I know that often with cancer, the C the big C is often
- 5:10referenced, But when I think of the this, I think about the word cured.
- 5:14And I'm wondering, doctor, I, is that a thing?
- 5:16Can colon cancer be completely cured?
- 5:19Is that possible?
- 5:20Dr. Irena Rupp:
- 5:20Yes.
- 5:21So if we look at, SEER database, which is, run by the government And that looks
- 5:26at survival rates for the last five years and it's an a rolling five-year basis,
- 5:3165% of all diagnosis of colon cancer will survive five years and achieve a cure.
- 5:37So 65% of all of those who get diagnosed with colon cancer
- 5:41will survive five years plus.
- 5:43And that's actually a wonderful result And we are improving on
- 5:47that result every time we reassess.
- 5:50So that number has, if anything, has gone up and up and up over the years.
- 5:54So cure is absolutely possible, particularly.
- 5:57Cure is extremely possible when we're talking about lower stage colon cancer.
- 6:02So stage one, two, or three where the tumor has not gone to any other organs
- 6:07and has stayed either in the colon wall or colon wall and lymph nodes.
- 6:13Once the tumor has gone to other organs, the cure is much more difficult
- 6:18to achieve because you then are talking about medical and surgical
- 6:23intervention on multiple organs.
- 6:26In a lot of cases That is still possible and there is possibility of cures in
- 6:31some situations, but it is not widespread and survival goes down substantially
- 6:37in the stage four disease where the tumor has spread to other organs.
- 6:41Scott Webb: right will.
- 6:43Some folks need a colostomy bag after colon cancer, doctor
- 6:46Dr. Irena Rupp:
- 6:46in certain situations That is a possibility.
- 6:48Usually when we are talking about kind of acute situation
- 6:52where somebody's very, very sick.
- 6:54The tumor has caused a bowel perforation.
- 6:57So there's a hole and there are stool leaking into the abdomen, And
- 7:00the patient is really too sick to be tolerating reconstruction at that point.
- 7:05In other situations, the tumor can cause, , obstruction, so a
- 7:09blockage to the point that, again, you're getting very, very sick.
- 7:12, And we have to remove it and do things quite expediently, to save a life.
- 7:17A lot of those, ostomies, whether they're colostomies or temporarily
- 7:21ileostomies, can be reversed.
- 7:23And a lot of the times they do get reversed.
- 7:25A lot of that reversal is really up to how well are we doing with
- 7:29the rest of disease control?
- 7:31What are our other underlying morbidities?
- 7:34Heart, lung, liver, kidneys, and are we able to tolerate a second operation?
- 7:39Scott Webb: of course.
- 7:40Doctor, are there any signs or symptoms that colon cancer has spread for folks
- 7:45and I, I guess it makes me wonder, you know, for somebody who maybe
- 7:49was in stage one and is advancing through the stages, like how fast does
- 7:52colon cancer spread or can it spread
- 7:55Dr. Irena Rupp:
- 7:55That's a very good question.
- 7:56Colon cancer actually is a, interesting process because it has a varying behavior.
- 8:02So depending on the type of mutations that led to the tumor being there, it
- 8:07can actually be indolent and there for years, or it can spread very, very fast.
- 8:13So not all colon cancers are created equal.
- 8:15There are some very small tumors that can spread fast, and there are
- 8:19some very large ones that never do.
- 8:21So the behavior of it is, is very different.
- 8:24How do you know that It's sort of what can be some of the
- 8:26signs that it's progressing?
- 8:28It can be very subtle.
- 8:30And I'll be honest, a lot of the times when we see patient's who
- 8:32have progressive disease, they don't necessarily have a whole lot of
- 8:37symptoms, that are acute or severe.
- 8:40That would tip us off that This is happening.
- 8:42Some of these things get found out on incidental scans for other
- 8:46conditions or other concerns.
- 8:48Some of the common signs that we notice are.
- 8:51Just generalized a feeling unwell, particularly feeling very tired, weak,
- 8:56dizzy, irregular bowel movements were previously, that was not the case.
- 9:01More abdominal pain, weight loss, that's not explained and
- 9:05not, , due to diet or medication changes, abdominal or rectal pain.
- 9:10Particularly once that's persistent and not just a episodic and goes away.
- 9:14Scott Webb: right, not just a, you know, well my stomach kind of hurts
- 9:17today, but it's, some of these, you say that it's, it's persistent.
- 9:20Give you a chance.
- 9:21Doctor, I really appreciate your expertise today.
- 9:23Talk about any advancements on the horizon that you're aware of when it comes to
- 9:26colon cancer screening or treatment.
- 9:28you mentioned about the survival rate, how it just keeps going up, which is
- 9:31just, you know, great news and brought a smile to my face, but anything else?
- 9:34Dr. Irena Rupp:
- 9:34Yeah.
- 9:34So a couple of things worth mentioning about colon cancer is that it is shifting
- 9:39to be the disease of younger adults.
- 9:41Currently it is the number one cause of cancer death for both
- 9:45men and women under the age of 50.
- 9:47So if you think about that, that's the population that generally is,
- 9:50has a pretty low mortality overall, but that's the number one cause
- 9:53of death for adults, less than 50.
- 9:55So, it is shifting to be a disease of younger adults And the fact that mortality
- 10:00and, prognosis is getting better, that's.
- 10:03Based on the fact that we are screening and doing a pretty good job with older
- 10:06adults, but we are not doing well enough with younger adults because a
- 10:10lot of them are potentially under the screening age, which is currently 45.
- 10:14And younger adults are increasing at about 3% per year in incidence of
- 10:19colorectal cancer in this country.
- 10:21So This is kind of the, big, gap where we are not screening, these
- 10:25patient's because they're not yet coming due for a standard screening.
- 10:29We're doing very well with the adults for screening.
- 10:32What are the screening modalities?
- 10:33So there are a number, There are several, stool-based tests, and
- 10:37some of those can be done at home.
- 10:39One of them is Cologuard.
- 10:40It has an excellent, sensitivity, so ability to detect colon cancer.
- 10:45I will say that it also has a 8% false negative rate.
- 10:49Which one must always remember that that's not zero.
- 10:51It also has a false positive rate of 13%, meaning comes back abnormal,
- 10:56but there's actually nothing found.
- 10:58There's also a fit test that's fecal immunohisto skull test, and That
- 11:02is, also a very good sensitivity, a bit less than Cologuard, along
- 11:06the lines of, you know, 73 to 93%.
- 11:09But both of those tests, are not as good for detection of adenoma,
- 11:14a type of polyp that, you know, ultimately develops into colon cancer.
- 11:18Both of those tests are along the lines of 40, maybe up to 50% for adenoma detection.
- 11:24So they're very good for cancer.
- 11:26They're a little bit, under PPAR for adenoma, And for that colonoscopy
- 11:31still remains the gold standard of care for both removal and detection.,
- 11:36Of adenomas and, colon cancers.
- 11:39There are additional things on the horizon.
- 11:42As far as screening for colorectal cancers, there are a number of companies
- 11:46in the world that are working on blood tests for, and not just colon
- 11:50cancer, but a multitude of cancers.
- 11:52Some of Those are FDA approved.
- 11:54The unfortunate thing about those tests is that although
- 11:57they are easy to do, they're.
- 12:00Ability to pick up colon cancer, especially at early
- 12:03stages, is still quite poor.
- 12:05So substantially less, you know, viable alternative to a stool test or the
- 12:11gold standard, which is colonoscopy.
- 12:13I will also say that those that have symptoms have inflammatory bowel disease,
- 12:18have family history of colon cancer, should really have a colonoscopy as the
- 12:23screening exam because of its ability to,
- 12:26detect adenomas, which ultimately can lead to cancer faster in those circumstances.
- 12:32Where a stool-based study or a blood-based study will often not detect pre-cancerous
- 12:38lesions and may give a false sense of security that things are well.
- 12:43But family history is particularly one where colonoscopy, should be
- 12:47favored over a stool-based study.
- 12:49Scott Webb: Right?
- 12:50Yeah.
- 12:51And as you say, it remains the gold standard for now, , for a reason, and
- 12:54you've given us some of the reasons today.
- 12:55So appreciate your time and your expertise.
- 12:57Thanks so much.
- 12:58Dr. Irena Rupp:
