"Pretty sure we all know the difference between in situ and invasive but that just tells you how little they knew."
Honestly, it didn't sound like you did know the difference when you posted the above. But if you're saying your team didn't know the difference, then you probably should have gotten a different team. Early stage in situ is Stage 0 and "IDC in situ" doesn't exist.
Just because there was almost nothing on Google about your type of cancer does not mean that doctors didn't know how to treat it. I would hope you didn't choose a team that looks to Google for treatment decisions.

Barbe...hmmmmm....you say:
"So basically VR you are saying that no one with a tumour less than 3 cm like the OP should bother answering?"....No! That is NOT what I said.
This is what I said:
"When newbies post whether or not they will be offered chemotherapy could you explain the process properly or not say anything at all? You just confuse newbies when you say your surgeon said to save "the big guns for later."
The process includes a medical oncologist visit. The medical oncologist may request genetic testing. The medical oncologist will go over the research, guidelines (based on standard of care), statistics, risks, health of the patient, characteristics of the tumor and the patient's wishes before offering an opinion. The medical oncologist will also explain that depending on treatment, that may or may not include chemotherapy, the protocol will hopefully spare the patient from revisiting this disease in the future."
#################################################################################################################################################################
Once again I will recap...beginning with what you initially said (including your signature). BTW, this is usually what you often say when newbies bring up the question of chemotherapy....
Barbie said on this thread:
"If they say no chemo it means the chemo won't work on your tumour. There's no point in doing it as it won't make a difference. That's why those tests were implemented. There was nothing like that when I got my breast cancer 8 years ago - they just guessed and/or threw everything at you if you wanted it. My surgeon said to "save the big guns until next time" so I did. I went 7 years without a recurrence and with just surgery. No Tamoxifen or radiation, and no chemo.
I did recur, but got 7 years NED. Would I have recurred if I'd had chemo 7 years ago? Probably. The cancer grows at it's own rate in it's own time. If chemo isn't going to work why take it? Some women go from doctor to doctor to get second, third and fourth opinions until finally one of them says what they want to hear. Be careful."
Dx 12/10/2008, IDC: Papillary, Left, 1cm, Stage IB, 2/5 nodes, ER+/PR+, HER2-Surgery 12/16/2008 Lymph node removal: Left, Sentinel; Mastectomy: Left, RightDx 2/4/2016, IDC: Papillary, Left, Stage IV, ER+/PR+, HER2-Hormonal Therapy 2/11/2016 Arimidex (anastrozole)Radiation Therapy 2/17/2016 Whole-breast: Lymph nodes, Chest wall
Point #1. You said that your "surgeon said to "save the big guns until the next time" so I did." NOWHERE DO YOU MENTION THAT YOU RECEIVED THE OPINION OF A MEDICAL ONCOLOGIST WHO IS THE CLINICIAN THAT MAKES THE RECOMMENDATION TO HAVE OR FORGO CHEMOTHERAPY.
IT ISN'T UNTIL MANY POSTS LATER THAT YOU TELL US THAT YOUR CASE WAS PRESENTED TO A TUMOR BOARD WHERE I ASSUME A MEDICAL ONCOLOGIST PARTICIPATED IN MAKING A PROTOCOL RECOMMENDATION.
Point #2. Then you tell us:
"I asked my surgeon what the fastest way to get back to work would be. He said if I had a mastectomy I could avoid chemo. So I did. Why is that confusing?????"
Confusing??? Of course it is confusing. In fact, your statement is beyond confusing. AGAIN, THE SURGEON IS NOT THE PHYSICIAN WHO MAKES THE DETERMINATION WHETHER OR NOT ONE NEEDS CHEMOTHERAPY BASED ON THE STANDARD OF CARE. However, IF the surgeon is part of the tumor board, then he can make a SUGGESTION that the tumor board considers. That said, FOR AS LONG AS I AM READING THE NCCN BREAST CANCER TREATMENT GUIDELINES IT HAS NEVER SAID THAT ANY PERSON WHO HAS A MASTECTOMY FOR INVASIVE CANCER DOES NOT NEED CHEMO. The surgery has no bearing on whether or not a person requires chemo. AS you quote cancer.net...and as I have said, over and over and over again, a chemo recommendation is based NOT ON THE TYPE OF SURGERY BUT IT IS DETERMINED BASED ON THE PATIENT'S TUMOR'S CHARACTERISTICS, THE AGE OF THE PATIENT, THE HEALTH OF THE PATIENT AND THE WISHES OF THE PATIENT.
Now.... point #3...
You tell us that you did your own research, but you say:
"I have no idea what the Standard of Care was in 2008 here in Canada. I did what I was comfortable with and haven't looked back. Ever"
That is fine! Everyone should be comfortable with their treatment decision....BUT, don't you think everyone should have a right to know what the Standard of Care is? Clearly, you did not know it nor did you care to know it when you decided what treatment was best for you. But as so many of us have tried to tell you, based on the Standard of Care in 2008, you were under treated. Now had you been treated according to the NCCN guidelines of 2008, there is no way of knowing if you might not have recurred. But, even that is NOT what I take issue with. What I take issue with is that you tell the OP that your surgeon told you to save the big guns for later. And while I believe s/he could have said that, THAT STATEMENT IS NOT SUPPORTED ANYWHERE IN ANY GUIDELINE FOR ANY YEAR! When physicians initially treat an early stage breast cancer patient, they do so with the intent that treating based on the Standard of Care will hopefully avoid a recurrence.
Barbe, DO YOU UNDERSTAND??? No physician, unless a patient is Stage IV with an ER + tumor would ever say such a thing. Ever.
Now point #4...
rare breast cancers... I had one, as well. And yes, the treatment guidelines for rare breast cancers are not as robust as they are for the more common types of breast cancer. And that is why it is of great importance that patients with rare breast cancers get many opinions. We are not in a "gray" area when it comes to treatment options. We are in no area at all because the rarity of our tumors creates less hard data to use as a framework for guidelines. So, the point that you make that you did your own research and that your listened to your surgeon defies common sense and logic. My team made it very clear to me that there was little evidence (research) to work with to make an absolute treatment recommendation. Luckily, as I said before, the OncotypeDX test had just been FDA approved (although it still hadn't been written into the guidelines) and they made their recommendation using info from two pathologist reports and the genetic test. But, they were confident that they were not over or under treating me. With a "favorable" type of cancer, I was fortunate to be given several good choices.
So...Barbe...DO YOU UNDERSTAND? AND DO THE PEOPLE PMing YOU UNDERSTAND? IF THEY DON'T, THEY ARE WELCOME TO PM ME.
I really can't understand why you don't understand that many of us have lost our patience with you??!! That is, do you consciously choose to obfuscate the true details of what initially transpired when you were diagnosed, or were you NOT given proper guideline recommendations? If what occurred was the former, than so be it. If it were the latter, then IMHO it was malpractice. So which one was it? And if you can't answer, then at the very least will you please not continue to chime in and tell newbies that your "surgeon told you to save the big guns for later." That is just plain irresponsible of you to mention. Sisters come here to get solid information. Statements like yours are not just irresponsible, but frightening to early stagers. Aren't they frightened enough? You shouldn't be giving them that kind of answer. Enough, already! Okay?
-
Very interesting and informative VR. You definitely have done your homework.
Let me just add my 2 cents worth to your comment about who the decision maker should be about treatment - you and your MO jointly.
I had a lumpectomy(Stage 1b, Grade 1 IDC) and when the path report came back it showed a micromet in my SN. My BS told me it would get me chemo. I let him know it wasn't his call; my MO would decide treatment.
She was ambivalent about treatment and informed me that too many women were over treated so she ordered the Oncotype test. Insurance paid thankfully. My score came back@11. 8% chance of recurrence with 5 years of Tamoxifen. I dodged chemo because of that test so she recommended 33 Rads treatments. I was 5 years out in August. Tamoxifen ended too.
I appreciate your persistence in clarifying what newbies need to know. It's a shame it had to become a verbal volleyball. We shouldn't have to be defensive about our choices but neither should we declare them to be gospel because IMO in this case they were not. While I didn't want to have chemo - let's get real who does- quite frankly I would have been afraid not to. I refused to play Russian Roulette with my life. Would chemo have prevented a recurrence in this case? She will never know for sure. That's scary.
Diane

I am not declaring my choices as gospel and have never said as much so please don't twist my word again. have told you what happened to ME. There was very little info to go on and I will say for the 5th or 6th time (if anyone is even bothering to READ what im actually saying instead of thinking they know) that Oncotype and Mammoprint tests were NOT available so we had to go on suggestions and recommendations based on historical results or stats if you will. Of COURSE a tumour board reviewed my pathology as it was a very rare cancer and they needed help deciding on treatment. That is a given. Even my double masts had to be approved by the board as we don't tell surgeons what to do, they tell us our options. I WAS TOLD I COULD AVOID CHEMO BY HAVING A MASTECTOMY to get me back to work the quickest.
I am NOT telling others what to do I was merely responding to the title of this thread.
Even the poster Edwards above says her onc was "ambivalent" and felt too many women were over treated.
We're more testing options available at my diagnosis this all could have been cut and dried. But I don't understand why you keep thinking I should have had chemo????? After careful consideration about MY tumour and MY treatment choices chemo wasn't even in the mix. The only thing I hemmed and hawed over was radiation and/or Tamoxifen. That's it.
I don't understand your comment about a stage 4 er+ patient and understanding the comment. Huh?
Why do you feel your doctor's and your choices were right and mine were wrong? THAT is what I don't understand. I'm trying to understand but don't yet. And why do you blow over my links to USA websites about early stages not always needing chemo? Isn't that what all the new testing options are so great for?
-
Happy holidays Barbe, I'm sorry this forum has become so confrontational. You have been through a lot, and I have seen you post on several forums and I feel you wish everybody the best and your intentions are good. Frankly I am shocked this forum has become so confrontational, I'm pretty sure that isn't what it is intended for. For what it's worth, my oncologist told me 70% chance of no recurrence or metastasis if I didn't do chemo or any further treatment. I have also read here on other forums that 30% of early stage breast cancers will metastasize no matter what. I haven't been able to figure out where that information came from, but if it is true, then in my head I wonder how much chemo actually did for me. And that forum (which I have now blocked) scared me as I have/had stage 1 breast cancer. I'm not sure where the factual evidence is to back up the 30% number, but now it is in my head and I can't get rid of the "statistic".
-
diane...thanks for commenting and congrats on celebrating 5 years NED! Your eloquent point about our decisions and gospel reminded me of the late U. S. Senator Daniel Patrick Moynihan famous quote — 'You are entitled to your opinion. But you are not entitled to your own facts.' And, recently I saw author Michael Lewis interviewed by Charlie Rose. They discussed Lewis' new book (which is sitting on my coffee table), The Undoing Project based on the lives of these two researchers. Rose asked Lewis if he shared the manuscript with the surviving researcher. Lewis replied that he hadn't. But, he continued, that he had warned the researcher that when the book would be published, and he read it, he might not be pleased with some parts that he had written. But, he also told the researcher that he had hoped that he would like the book. Lewis further told Rose that people's perceptions of themselves and events may not be accurate and it is the job of a good non-fiction writer to interview as many people as necessary and read as many documents as possible to create a narrative that is as close to the truth as possible. I guess that is where the expression ""Sometimes the Truth Hurts" comes from. Sometimes we need to step back and try to piece together the truth because what we think is the truth or what we think may be a fact, ultimately mmght not be....
So, with Barbe, may she be blessed with many, many, many more years, we have a narrative that is repeated endlessly which simply should not be accepted as a plausable experience because at first blush it contains holes. And it is not until she is called out to elaborate that she attempts to fill in the holes. But even then, the holes get bigger and so, we are no closer to getting a better picture of what her experience might have actually been.
Now what is truly frustrating for those of us, like you and I, who aren't newbies, is that she, in sage mode, fails to see what is in plain sight. And that something has been told to her, in what seems to be countless times,is that it is the medical oncologist's job and not the surgeon's to tell us if we are candidates for chemo.
No one has ever admonished her for not doing chemo. We all are big girls and each of us needs to make our own decisions and we each do what we think is right for ourselves. But that doesn't mean that sisters can come here and create a false narrative that can ultimately harm a newbie's decision process or worse, harm a newbie's psyche. My heart would ache if I confused a newbie or gave them false hope or gave them wrong info. And I have seen countless sisters do that to newbies more times than I would care to count.
So, I am sorry that I hijacked this thread, but I hope when sisters read it, especially newbies it will help them thru the maze. And for those well worn sisters, I hope it will give confidence to chime in when they see fallacies and try to set the record straight.....

barbe...I am not saying you should have had chemo. I said you should have been presented with the standard of care by a medical oncologist. i also said that a mastectomy has no bearing on whether or not chemo is warranted. You keep insisting your priority was the protocol that would get you back to work the quickest. The protocol that would get you back to work the quickest and the standard of care might conflict with one another. So, your surgeon's statement about saving the big guns for later coincides with your objective of returning to work quickly and conflicts with the standard of care.
So, if a newbie's objective is to do the fastest protocol then telling them your surgeon recommended saving the big guns for later is GREAT advice. But if a newbie wants to understand what lies ahead, then the best advice would be to tell them to read the NCCN's guidelines and then discuss the guidelines with their MEDICAL ONCOLOGIST...and if they are still uncomfortable or in a gray area, then they should get a second opinion and/or have their case reviewed by a tumor board.
Btw...Barbe...if you ever look me up on this discussion board, you will see that that is the advice that I give most of the time.
So please get your story straight and explain the caveats to newbies before parsing my words and taking umbrage
-
VR - your relentless efforts to define what the real issue is in this "discussion" continues to get lost in the translation and I don't understand why. This conversation has become a defensive tug of war instead what it was intended to be and that is for information only.
I have a friend who is a nurse at St. Jude so she is all too familiar with cancer although her patients are primarily children. She had breast cancer
and had a double MX. Coincidentally she and I have the same BS. He is one of the best in town and also one who is all about saving the breast. Obviously that isn't always possible. My friend insisted on a MX despite his objections and in fact took her concerns to the director of the West Clinic - very well known cancer clinic in town. She conferred with him and had the MX followed by chemo and radiation. Point being the MO called the shots - a point you have reiterated in your posts.
We all know there are no guarantees but I too am troubled by the "saving the big guns" statement. The big guns need to be used on the front end if applicable.
I have read many of your posts. You are very well informed and I never viewed your posts as personal attacks on anyone.
Last time I checked we were all on the same side. We were and are deluged with information about breast cancer so we need to be diligent about where to go and who to go to to get the best advice.
Every doctor we consult with throughout the process has their own expertise. Btw my MO told me in no uncertain terms she was in charge of my treatment plan.
I hope the newbies will sort through the she said she said and make their decisions accordingly.
Thanks for the congrats on the 5 year milestone! It's hard to believe it's been that long already. I truly am blessed.
Diane

Barbe, as I recall you also refused hormonal treatment, until being diagnosed as Stage IV. Is this correct?
-
- Merry Christmas 🎄 Happy 😊 New Year! Happy holidays to all. Best wishes in your BC treatment!
- I am always appreciative to sisters, such as VR, who share their research, experience and expertise. Much thanks, VR, for your guidance!
- Other sisters of the "low information" type might best "back off" rather than sharing fallacies and misinformation for the benefit of newbies.
- Good luck to OP in your early January surgery. Hugs & healing!
-
Mary, to try to answer your question:
It is too early to tell if you will need chemo. if the pathology comes back with more than 3 positive nodes, you will be recommended chemo. If you have 0-3 nodes, then they will do an OncotypeDX to see if chemo is appropriate and necessary for you.
If the doctors, based on the above, tell you that you don't need chemo, then you are most likely better off not doing it. Chemo carries risks of its own. When doctors do NOT recommend chemo, it is because the risks of the chemo are equal to or greater than the risk from the cancer itself.
If your situation, for whatever reason, is not clear-cut, then a tumor board should get involved and/or you could seek additional opinions.
The waiting is awful, but for now, you basically have to sit tight until the path report from your surgery is in
-
Sigh....I was not spreading fallacies I was only sharing my own experience.
I'm sorry you weren't able to make decisions about your own treatment plan because some of those treatments have now been proven useless. Sad really.
I filled in holes in my story when I realized what I was being questioned about. I did not do any of this blindly like a sheep. I have a brain and I used it.
Merry Christmas.
-
ItalyChick, the reason for the "confrontation" is because there are a significant number of us who are aggravated by blatant misinformation being spread.
In regard to your questions about the 30% statistic, perhaps it would be a good idea to read the thread rather than blocking it. The answers to your concerns lie within the many pages of that particular thread, such as where the number comes from. Also, although it is repeated often in that thread, you wouldn't see it if you've blocked it, but the statistic is 30% of early stage (stages I-IIIA) not 30% of stage I. So, before you start questioning how effective chemo was based on that thread title, it would probably be best to familiarize yourself with the information. Once most people discover the nuances of that statistic, they usually realize that it's not really telling us anything we didn't already know.
-
This is a scary place.
-
Blatant "misinformation" backed with links to the ACS? Really??? I hate when people twist others' words to match their perception of reality. If they didn't live it then it must not be true. Sheeple.
Yes it is a scary site when one person disagrees with another and then the Sheeple jump on the bandwagon and blast away without even knowing what they're talking about.
Would be laughable if it wasn't so sad.
-
Yes, blatant misinformation. It's been discussed on multiple threads over the course of a long time.
Your ACS postings had NOTHING to do with the conversation at the time. Absolutely NO ONE said that all breast cancers get chemo. You were applying irrelevant information to the discussion and then attempting to use that to buttress your claim.
Anytime anyone uses the word "sheeple", I laugh because it says so much more about the person using the word than those they are attempting to describe.
Barbe said: "I'm sorry you weren't able to make decisions about your own treatment plan because some of those treatments have now been proven useless. Sad really."
...And there it is, I was wondering when it would show up. When people get tired of your spreading of misinformation and deliberately obfuscatory remarks, you make petty and vindictive comments about how their treatment was worthless. That's what's sad...really.
-
Barbe1958, forearmed with correct information is forewarned. For the newbie's sake, please post only fact-checked information. Also please grant the medical community more credit than diminishment of their respective resources. 17 hours ago you stated here that your physicians "didn't know what to do" or how to test you back in 2008. I beg to differ. Medical studies on papillary carcinoma dated back decades, serving as reference to dx and treatment of papillary carcinoma BC. Some examples of studies that existed prior and during your Dec. 15, 2008 diagnostics are ....
2008 - Univ of Taiwan (see Nov. post on papillary thread)
2008 - 917 Cases, Grabowski (California)
2009 - Esposito study Basement Membrane
2006 - Nassar et al
And there are others, if you care to consult with your doctors. Sisters being newly diagnosed should feel encouraged by current medical research. Hugs to all.
Merry Christmas 🎄

Barbe....here we go again with this tired discussion which you still seem not to grasp. You say:
"Blatant "misinformation" backed with links to the ACS? Really??? I hate when people twist others' words to match their perception of reality. If they didn't live it then it must not be true. Sheeple."
Here is the guideline that you referred to from the ACS:
"If the tumor is smaller than 1 cm (about ½ inch) across, adjuvant chemotherapy (chemo) is not usually needed. Some doctors may suggest chemo if a cancer smaller than 1 cm has any unfavorable features (such as being high-grade, hormone receptor-negative, HER2-positive, or having a high score on a gene panel such as Oncotype Dx). Adjuvant chemo is usually recommended for larger tumors."
And my reply:
"Now....you are pointing out to me what the guidelines for treatment for tumors that are LESS than 1 cm. Excellent. At least there is no disagreement with respect to the breast cancer treatment guidelines."
Did I challenge that information? No. And then I go on to say:
"Who are those guidelines written by? I will tell you. Medical Oncologists. Medical Oncologists get together and create a treatment guideline that establishes a standard of care. So, either before breast surgery or after breast surgery, a patient meets with a medical oncologist and as you quote from Cancer.Net: "Not every person diagnosed with breast cancer needs chemotherapy. Your doctor considers several factors when deciding if chemotherapy is an appropriate option...."
Am I disagreeing with you? No. The relevance of this information was that I pointed it out to YOU suggesting that both you and the OP with tumors at 1 cm or greater SHOULD BE REFERRED TO A MEDICAL ONCOLOGIST so that an informed decision could be made about whether additional systemic therapy might be needed, SO THAT THE DISEASE MIGHT NOT BE REVISITED IN THE FUTURE.
And now....what do you do? You bring up the ACS's points which are germane to the issue being challenged....and that is YOU TOLD THE ORIGINAL POSTER THAT YOUR SURGEON TOLD YOU THAT CHEMO WAS NOT NECESSARY AND TO SAVE THE BIG GUNS FOR LATER.
THAT IS THE ISSUE! IT IS BLATANTLY WRONG FOR A SURGEON TO GIVE THAT INFORMATION TO AN EARLY STAGE ER + PATIENT AND IT IS OUTRAGEOUS OF YOU TO REPEAT IT.
So what do you do when I confront your narrative...you create holes......
The holes...
You didn't disclose until challenged:
1. Your case WAS presented to a tumor board and they didn't recommend chemo.
2. You asked your surgeon what was the quickest protocol so you wouldn't miss too much work
3. You wouldn't do chemo because you saw your beloved father succumb to cancer despite doing chemo
4. You didn't know or care what the standard of care was back in 2008 when you were diagnosed despite claiming you did your own research and decided with your surgeon that the quickest protocol
would have been to do a mastectomy.
So barbe...Do you still not understand what I take exception to?
Newbies come here to ask questions about navigating their journey...and instead of providing USEFUL information, you give directions to a rabbit hole.
And now, rather than concede that it is YOU who is providing "misinformation"...why do you instead try to gain the upper hand, like a petulant child in a school yard, you call me and others names? Barbe, why must you dig deeper into the rabbit hole?
You see a surgeon to decide if you want a mastectomy or lumpectomy.
You see a medical oncologist to decide what adjuvant therapy is or is not needed.
NO SURGEON SHOULD BE TELLING AN EARLY STAGE PATIENT THAT THEY DON'T NEED CHEMOTHERAPY BUT SHOULD INSTEAD USE IT IF THEY HAVE A RECURRENCE.
AND YOU SHOULDN'T BE SAYING THAT EITHER!
FINALLY, NO ONE IS DOUBTING THAT THAT IS WHAT THE SURGEON TOLD YOU. IT JUST ISN'T THE PLACE OF THE SURGEON TO MAKE THAT RECOMMENDATION. A CHEMOTHERAPHY RECOMMENDATION IS MADE BY MEDICAL ONCOLOGISTS BASED ON THE CHARACTERISTICS OF THE TUMOR, THE PATIENT'S AGE, MENOPAUSAL STATUS, HEALTH HISTORY AND PATIENT"S WISHES. OTHER PHYSICIANS MAY MAKE SUGGESTIONS...BUT THE JOB OF THE MEDICAL ONCOLOGIST IS TO GIVE THE PATIENT THE STANDARD OF CARE GUIDELINES, AND THEN TAKE ALL OF THE OTHER INFO INTO CONSIDERATION SO A PATIENT CAN MAKE AN INFORMED CHOICE.
-
Good point, we!
As a fellow rare breast cancer patient, you know as well as I how little research there is on rare breast cancers. But that doesn't mean that our teams of doctors are incapable of making a recommendation. Since my diagnosis, I get excited when I punch into Pubmed's search engine and find more and more info regarding mucinous breast cancer. While the data will never be robust for rare breast cancers, I still marvel at the number of researchers and clinicians who are studing and reporting on it. When I began my journey there seemed to be a dearth of info and it was all over the place. I decided to put whatever research I could find on the mucinous breast cancer thread so it would be easier for newbies to find. Sadly, that thread remains fairly active. The good news is it has helped numerous travelers...
We are all on the same journey.....
-
I got the Oncotype first and it came back as a 20 Intermediate. What a horrible middle ground! So then I got the Mammaprint as a second opinion (insurance refuses to cover it but Agendia is amazing and only bills patients $500 for the set of two test (blueprint/mammaprint). My Mammaprint came back low risk.. so I went with no chemo.
If you get a grey area Oncotype, I highly suggest getting the Mammaprint. There is no grey with that test.
-
Dear Soozy,
sorry you feel this is a scary place. Most threads are not as conversationally charged as this one. Please join other threads and don't leave just because this one may seem so ......can't think of the right words to describe without being critical
-
MaryToU, we welcome you to the community and are sorry that this thread has become confrontational. We feel that the points have all been well made, and that we'd like to get the discussion back to a calmer tone, and greatly appreciate everyone's help.
-
Bosumblues - I didn't know about the mamma print test either but fortunately for me my Oncotype score was low so it was a moot point anyway.
My sister's score came back intermediate. Her MO decided Arimidex was sufficient. She had a MX but no chemo or Rads. Conversely despite having a low score my MO recommended Rads - I had 33 treatments and took Tamoxifen for 5 years.
Diane
-
Lisey, have there been any studies done on the accuracy of Mammaprint beyond five years? I came across one that evaluated its use over a five year period, so I wonder whether any serious study was done to look at a longer period?
If I understand correctly both Oncotype and Mammaprint are mostly used by women with Stage 1 diagnosis and most stage 1 folks have an excellent five year prognosis whether they treat it aggressively or not. So I wonder how reliable Mammaprint test results are beyond the first five years from diagnosis. We would like to know how accurate their predictions are 15, 20 and 25 years from diagnosis.
Happy New Year to all!
-
when I was initially diagnosed, I had the OncotypeDX test and it came back at low risk of recurrence. Almost seven years out, my oncologist recommended the BCI test which confirmed my 10 year risk of recurrence in the very low range. Interestingly, when I was first diagnosed, independent from my physician, i checked what my risk of recurrence was at the cancermath.net websiteand their numbers which give you a 15 year risk, came back at an almost identical number that the BCI test had given me. So for me, all of the equations seemed to confirm one another and that is that, based on the characteristics of my tumor and treatment decisions, at 5, 10 and 15 years, I am at low risk of recurrence.
Now, with all that said, I find that most of these equations speak to the issue of recurrence of the original tumor. What is interesting though is that some of the meta analysis is showing that for us Er + gals, systemic endocrine therapy is also protecting us from new tumors in our other breasts.
What I think is a quandary for some of us at low risk of recurrence is do we discontinue treatment at the 5 or 10 year mark because there doesnt seem to be any statistical significance of doing so to reduce our chance of recurrence, or do we stay in treatment for the full 10 years hoping it protects us from a new tumor?
Now Muska's question is a good one...what about decades along?
Well, if you look back at the recent SOFT and TEXT trials, you will see that they were merged together because of the lack of events since the patients were doing well....
http://www.nejm.org/doi/full/10.1056/nejmoa1412379...
And the TailorX trial too hasn't given us enough clear evidence beyond the very low risk catagory, again because most of the people in the low risk categories had very low risk of recurrence in the first place...
So, with all these new treatments aimed more precicely at patients, the good news is that it seems that many patients are doing exceedingly well...and the negative news is that it will take many more years to identify EXACTLY who should benefit from more treatment..
-
muska.. in some cases, as part of a study,,now,stage two up to 3 positive nodes can also have the OncotypeDx test as long as they are also ER positive and her 2 negative
-
Thanks, Voracious, i am aware of Oncotype now being used with up to three positive nodes. However, I think in the majority of cases, it's used by stage 1 women who need to make chemo/no chemo decision.
If I am not mistaken there have been more studies to assess Oncotype accuracy than on Mammaprint. But I may be wrong, hence my question above.
-
muska...
Most of these studies are continuing to follow up. so in a few more years we will be able to see how well those patients did...
The issue is that with targeted treatment, this population is doing really, really, well. So regardless that the Oncotype DX got FDA approval and it is written into the NCCN guidelines, it doesn't mean the makers of the test stopped collecting data.
Mammaprint and others are doing the same...so stay tuned!
-
Muska,
Previous to 2014 (I think) Mammaprint was only accepting non-formalin fixed tissue - so it wasn't available to most women who had their tumors fixed in Formalin. They changed their system and now accept normal Formalin Fixed tissue like Oncotype, so they are quickly gaining ground in the market. Mammaprint was just verified as a reputable source for women debating chemo - the study came out in August I believe.. but it's so new there's nothing on it for 10 years. It is widely used in Europe, more so than OncotypeDX, so the studies from Beligium on the non-formalin fixed tumors are pretty extensive.
