    Thanks Nancy..

    You brought up a good point about the cPR ( complete pathological resonse). I think a lot of woman do not understand that a cPR only happens about 30% of the time. Therefore, 70% of woman will have some sort of residual tumor or lymph node status. I think that woman may be getting really upset after their pre chemo pathology report..when if they were told about this 30% thing it wouldn't hit them as hard. I have a friend who was devastated at her path report after wards...even though her tumor shrank 80%,!!!! she had 2 lymph nodes involved, but her onc never mentioned that a cPR was most likely not going to happen.

    And Nancy is also right by saying chemo is not the only answer..there is hormonal therapy , rads

    Can someone tell me the study (study number or name) that is being referred to - that indicated that chemo isn't effective for ER+ cancer.

    Thanks,

    Some breast cancers don't respond to chemotherapy

    Last Updated: 2007-10-19 16:13:18 -0400

    NEW YORK (Reuters Health) - An analysis of the results of several studies confirm previous reports suggesting that chemotherapy offers little or no survival benefits for young women with estrogen receptor (ER)-positive breast cancers and, if given, it should not be the sole second-phase, or "adjuvant" therapy.

    "Developing breast cancer at a young age is very worrying in terms of survival," lead researcher Dr. Jos J. A. van der Hage, from Leiden University in the Netherlands, said in a statement. "But some young women may be undergoing not only unpleasant but also unnecessary chemotherapy."

    In the current analysis, the researchers examined data from 480 women with early-stage breast cancer enrolled in one of four EORTC (European Organization for Research and Treatment of Cancer) trials. All of the subjects were premenopausal -- younger than 40 years of age -- and the average follow-up period was 7.6 years.

    During follow-up, 155 patients died or experienced a distant recurrence, according to the report appearing in the current online issue of Breast Cancer Research.

    Patients with ER-positive cancers were significantly more likely to have a longer overall survival than those with ER-negative cancers, the team reports.

    Among the patients who received prolonged adjuvant chemotherapy, however, the difference in survival rates was minimal (70 percent versus 75 percent, favoring the ER-negative group, and rates of metastasis-free survival were 59 percent versus 70 percent, respectively.

    These results suggest that chemotherapy had a beneficial effect for women with ER-negative tumors, but had minimal or no effect on ER-positive cancers.

    Similar survival differences were noted for women with or without progesterone receptor-positive tumors, the report indicates.

    "Adjuvant chemotherapy is a well established, but ineffective treatment in ER-positive breast cancer patients aged 40 years or less," van der Hage emphasized. "Hormone responsiveness is the key to tailoring therapy in the future fight against this disease for young women."

    NancyD, you wrote: ".....you have to admit shrinking it (the tumor) more than 2/3 is not exactly not responsive......"

    See: that's exactly my problem with the current approach to treatment: research concentrates on tumor-shrinkage. But, as demonstrated by many independent researchers, and as painfully evidenced by the Recurrence/Metastatic section of this very forum: tumor shrinkage and overall survival are 2 completely different matters. Alas.....

    My point is that if they (Research) adopted a more open-minded approach to their great work, if they accepted to start looking in new, innovative directions, we could get past tumor-shrinkage, and move towards a real cure (overall survival).

    Tumor shrinkage is excellent news, for sure!! Great!! ......

    ...............Sadly, however, the more aggressive tumors (for ex: HER+, ER-, etc...) have that terrible tendency to recur. No matter what chemotherapy mixture is applied.

    And we are still doing the same old, same old, same..... Surgery, chemotherapy, radiation. Over and over and over and over and over..........................................

    I have several friends in my support group (one of them is sooooooo very close to my heart) who are exactly in that situation: they joined the group 5 years ago (actually, they pride themselves on being founding members of our group). They went through the whole treatment thing, and when I joined in turn, this dear friend told me exactly what you are saying now, in order to cheer me on right before I was to start chemo:

    "You know, chemotherapy REALLY works. Don't worry: it REALLY works."  Oh, how nice and encouraging they were to me......   And it breaks my heart to say: 3 of them are currently battling metastasis. Did chemo/radition keep the mets at bay for them for a few years? I am open to that suggestion, but knowing me, I doubt it seriously (in view of absolute/relative statistics, it looks unlikely to me). I am more inclined to think that the cancer was simply taking its time.

     Anyway, here we are, my friend and I: facing the revolting, heartbreaking situation of her progression to mets (she had one of the aggressive ones). Of course, my heart also goes out to the others facing the same situation in my support group. And everywhere.

    Wow

    This thread sure has made its way down a winding road. 

    First, on the original subject: I am ER(+) and when I was originally diagnosed I went to a well respected oncology practice in the area.  The oncologist that was assigned to me had just finished his fellowship at MDA and was supposed to be on the "top of his game".  He read through all of my information and then gave me information and encouraged that I join the TAILORx study.  He told me that he would not request the Oncotype DX test unless I joined the study.  He was all about clinical trials and research and I felt that I was in his eyes a breast cancer lab mouse.  He told me that most likely I would have chemo given my markers but that the study would randomly assign me to a group based on my markers and we would choose the treatment options based on that.  (NOT!!!!!! for me)

    I called around to other women in the area who had recently gone through breast cancer treatment.  One of my neighbors had gone through chemo with this same oncology practice.  She said used them because they were well respected, highly regarded, top of the game etc.... and then after her treatment she started reading about the fact that based on her markers (high ER+) chemo probably was a waste of her time and energy - she had two kids under the age of 3 at the time of her chemo. 

    She referred me to my current oncologist who immediately ordered an Oncotype DX and then sat me down in front of a computer with incredible graphics including bar graphs, line graphs, statistical analysis all in a colorful power point format.  After impressing me with the statistical analysis including relative risks, absolute risks etc etc, my current oncologist said: "based upon your current information and tumor markers, the risks associated with you having chemo are higher than the benefits you would derive from getting chemo".  Thank God she was well versed in statistical analysis.  And my decision was made!

    So to address another line of conversation going on in this thread.  I believe that conventional medicine is an important aspect of treatment but not all medical practitioners look at medicine in the same way.  Just like not all patients look at medicine the same way.  The first oncologist was a researcher at heart.  He was looking at a more long term view - lets put all bc women in this study so we can get data for the future......I was not his type of patient.  Although I am appreciative of those women in clinical trials, this particular trial was not for me at this time in my life.  The second oncologist was looking at the short term, what is best for this patient at this moment in time- based on what we know now and what she will tolerate and she backed it up with an appropriate statistical analysis. 

    So I had a bilat mx, no chemo but was put on Tamox.  I then started looking to Augment my conventional medical choices with alternative choices.  I guess I think that people should make the personal choices that they can live with.  There are really no guarantees .... especially with this type of diagnosis.

    I would add this: chemo was not just a waste of your friend's time and energy: chemo carries a 3% risk of developing leukemia in one's lifetime (and this is written in the papers that they make you sign beforehand).

    I commend you on taking matters into your own hands, doing your own research, and making your own decision. My story is that I did not do that. I went right along with chemotherapy, because I did not know any better. After going through 5 out of 6 rounds of chemotherapy, I sought a second opinion and discovered that, based on my Oncotype-DX, WHICH MY FIRST ONCOLOGIST HAD ORDERED AND NOT TOLD ME ABOUT, and also based on my markers, I was not supposed to have chemotherapy at all (I am ER+, PR+, HER-). At that point, I fired my first oncologist, and stopped chemo at 5 rounds.

    But the damage is already done: this absolutely useless chemo INCREASES my lifetime cancer risk by 3%.

    You also wrote: ".....  The first oncologist was a researcher at heart.  He was looking at a more long term view - lets put all bc women in this study so we can get data for the future......"

    You are being much kinder to your first oncologist than I would be: they have been loading everybody with chemotherapy for more than 20 years now, before they "discovered" that it does not work at all on ER+. So I don't see what long-term data he would be looking at. This is probably somebody exactly like my first oncologist: he is convinced that the old way (chemo) is the only way to go, and he is going to go that way in total disregard of the evidence.

    Yours was going to put you through chemo without requesting your onco-type, mine simply refused to give me my results. In both cases, I feel they did what they did because they wanted to put us through chemo at absolutely all cost. So they did not want us to have too much information (probably felt that it would be too much knowledge for our own good).

    Sorry if I sound sarcastic: I am not. Just trying to state facts about the sad, sad, current state of medicine.

    PT63,

    About your doc being a researcher at heart. I agree with Yazmin that there is another perspective.

    My friend was almost talked into one of these random studies but asked me to read the consent form because English was not her first language. The study was at a large comprehensive cancer center. What the many-paged form disclosed was that the doctor received a finder's fee and had a financial stake in the outcome/ patent, etc.

    I didn't know this conflict of interest was actually possible. Apparently it is legal so long as the doctor discloses it. Well, he didn't actually disclose it to my friend's face. The disclosure was buried in the fine print.

    A lot of patients are vulnerable and want to please their doctors. They put all their trust in them. And not until it is too late do they realize their "wonderful, caring" doctors have sold them up the river.

    Any professional whose time is used in a clinical study should be reimbursed for that time. No doubt the most logical way to do that is on a per-patient basis.

    Do you think doctors work for free ... anywhere?

    Since it is clearly stated in writing, what's the problem? That someone who couldn't understand English ... couldn't understand English?

    LJ13 - "What's the problem".. of course no one expects doc's to work for free, but the clinical study could be scewed by this type of practice - what am I saying most studies ARE scewed by this type of practice..  It takes no time at all to suggest to a patient that they include themselves in a clinicial trial or study - there is no need to pay for that piece - only the piece where the doc's review the patients dx and treatment to see if it falls under the criteria of the trial.. and that is done by an agent for the trial.. that doc is paid in full.  This IS a real problem in medicine whether you agree or not and we are all paying the price for it.. We pay the doc's for a referral, the FDA get's paid by the drug and medical device people, etc etc etc.. What happens to the patient then.. What happens to "first do no harm".  We are suppose to be able to trust our doc's that they have our best interest at heart instead of their own interests.. Her doc was already paid for her visits.

    Deirdre - where did you learn that the FDA is "paid by the drug and medical device people"?? I worked for a large pharmaceutical company back in the 70's (a mere secretary) - I worked in the cancer research department - and the FDA swooped down on a drug that was nearly ready for market because one doctor falsified records. This was a doctor who wasn't employed by our company - he had his own practice 3000 miles away - but he was testing the drug on patients who DIDN'T exist! Thanks to the oversight of the FDA he was stopped - but unfortunately a very good drug study and millions of research dollars were wasted. The FDA agents, to my knowledge, were government employees on government payroll. I'd be interested in seeing any documentation you have that proves that the FDA is on the payroll of private companies. I can be a very jaded New Yorker - but I need proof before I accept this kind of conspiracy theory thinking.

    The FDA was once an organization with the intent to do good, not anymore and this is brought to the attention of congress almost on an annual basis..  Government approved (recently) the use of pharmacutical dollars to "help" the need of the FDA because they were always screaming "not enough money".. sorry it just isn't that FDA anymore!  I wish it were!  If you want proof just do a search within most newspapers and I believe if you do a search here on the alt site someone else had already brough forth the sites..  I don't blame you for not believing until you have proof - I felt the same!

    I actually was not trying to be kind to the first oncologist at all.  He was a researcher- his whole heart, soul, mind and body.  I am not sure that he personally was in it for money compensation as much as he was in it for data collection only -with no regard to the person in front of him.  I don't really believe that he cared for his patients at all nor did he care for the "old way" since he definitely told me that I would be randomly placed into a non-chemo vs. chemo group.  He was more interested in double blind, randomized clinical trials and most likely eventually being able to publish.  He should have worked in a research lab. 

     LJ:  There is a difference between being reimbursed for your time seeing patients and actively seeking subjects because of an incentive program. 

    I have not spent alot of time on the forum but I am a little confused on the reason you are so active in this particular area.  I was under the impression that this forum is a meeting place for those who are actively looking for alternatives not necessarily geared toward those who don't believe in them.

    I will bump up the thread about FDA...not all have outside interest but these reports show there is proof many trials have a lot of conflict of interest going on between all of organization.  I have done to trials and they were Phase I & II.  My doctor of course a MDA onc. went straight from there after two year to work for the pharm.  If you don't think this is big business, next time there is only news of research of a chemo drug just moving from one kind of a cancer to another (not even a new drug) you can watch the stock market and see the stock triple without even a phase I trial  completed.

    Let me give you guys a example of how a Phase I trial worked.  First I was un-educated about this stepping in. I was at the #1 cancer center in the world. (Big joke!) I had to very small local tumors and they would not let me see the bc clinic. Straight to Phase I and had four hours to make my decision to do the trial.  I ask about my expense because I would have to stay in a hotel out there for six weeks and fly back very month for tx.  Was told if I could handle this drug after the first tx they would pay my traveling. LIER'S! (cost me $7,000)  The other big thing is MDA cost triple to be treated there. My doctor who never even examined me did not know what kind of cancer I had or were it was.  Went to chemo and the nurse pulls me aside a told me don't let them do this too you!!! This was the sign I should have gotten the hell out of there. I was put through 34 blood drawer in 24 hours as part of the test. And many of test that was a joke.  After I got make to my room and got on the internet I found out the drug was already tested by Germany five years early and showed ZERO value in the tx of bc.  I made friend with the test nurse and she later told me that I did not fit the profile for the trial but they needed a healthy rat to up the response rate on side effects because I've aways handle chemo so well..  They did ZERO follow up on what happened to me, until one year later they called and ask if I had side effects.  Let's see...Level III neuropathy and could not walk for six months.  I asked if they still were doing the trials she laughed and said YES!  I ask how it was going...oh we have finding poor response and life threatening side effects. ONE year later still paying with this drug?

    I also found that they have ways to the trials look better.  This nurse and doctor talk to the pharm company daily. I was told not to give to much info on side effects in the meeting with the research nurse?? Only the check in nurse.  They would not do a PET scan on me only would do CT Scan every four months so you had be on the drug longer because seeing if you're having any response.  The pharm. company ran this trial not the FDA. If they FDA was involved why didn't they collect the data themselves? Why don't they have someone doing the follow up?  If someone is willing to do trials they should be PAID.  It's their life everyone is playing with.  Even if the drug works wonders the pharm co. will now make billions off it.  Avastin made 10 billion in two years. Where else in business do companies get free rats to try their product on?

    My big questions still is where was the FDA to protect me from this useless toxic treatment? Not  to say all the other's put through this trial behind me.  I did not meet one person it did anything for them. The other big thing I learn while out there....only 10% of the population needs to respond to a drug to get it approved!

    FDA looking at data AFTER people have been exposed to toxic drugs is not protecting them.  There has to be more research upfront. Second why does America need to redo complete trials after other countries have done years of study?

    Swimangle72:  I believe that Flalady has an entire thread that she has now bumped for you to see how FDA is today - I wish (truly I do!) that things were not as bad as they are but the FDA is no longer the watch dog - they are the hungry dog waiting for their dinner (money).  It was an incredibly good idea but like many good ideas some one took huge advantage for profit and for personal gain.  This is certainly not a conspiracy theory.. look around at what is happening to all sorts of "reliable" companies today and how they have robbed their clientell blind - FDA had almost absolute power at one time but "Absolute power corrupts absolutely"..  not exactly a new theory...

    Swimangel, evidently there is some proposal that companies submitting drugs and/or devices for FDA approval pay usage fees. Much like many people and companies pay usage fees for government services. Some people perceive this as a CONSPIRACY and a PAYOFF FROM BIG PHARMA. Of course, the fact that it is occurring out in the open, that it was proposed and approved by the legislative branch, doesn't seem to deter the conspiracy theorists.

    LJ13 - Conspiracy - your own projection?  This is what is termed as "conflict of interest".  Out in the open or behind close doors doesn't matter - Conflicts like this only make it impossible to have a safety board of any kind..  Conflict of interest equates to harm to the patient.

    The argument is untenable Deidre. People and companies pay fees to government agencies and private certification bodies all the time. If they are applied across the board, and otherwise implemented impartially, there is no conflict.

    I had neoadjuvant chemo and am HR+.  The oncologist can no longer feel the tumor in my breast or the one under my arm...not to say that parts are not still there as just feeling can't tell the whole story but it shrunk mine dramatically. Guess I will know more when I go in for surgery.

    LJ13 - Yes we pay FEE's to doc's too but expect them to follow a certain ethical protocol actually make them take an auth.. the FDA was set up and THEIR intended protocol changed when companies with a direct interest in their futures started PAYING FDA for their services.. you honestly don't see the difference???  Conflict of interest is a real problem in medicine.

    cp418:  I honestly wish I could say something positive too, I use to, but things have changed and someone, everyone needs to know they are not protected!  I'm with FloridaLady on this too and frankly it makes me question our entire medical system.  Yet I want to accept the good and thow out the bad.. I thought the government was doing some of that work for us!!!

    Congrats Deb-from-Ohio!!  Hope surgery turns up NOTHING too!!!
