Oncotype score-How can I be sure?

How can I be sure that a low score of 14 is really safe for me not to do chemo?

My doctor said that I have only a 1-2 % additional reduction in recurrence risk by adding chemo, and taking into consideration the risks, it is my decision. Yet chemo benefit is very small, if any benefit.

He sent me home to decide if I wanted chemo or not.  I have read all about the oncotype DX since, but I still have some unanswered questions.  With a score of 14 I know that by the clinical validation B-14 study it is considered low, but the TAILORx study is calling it a gray area of 12-25.  And it is currently being studied in that category.

Does anyone else have a low Oncotype score that elected not to do chemo, but still has questions since the results of the TAILORx study are still not out? I need to feel confident in my decision and hear from someone with a moderately low score whatever that means?

    It may help you to make your decision by reading the long term side effects caused by most types of chemotherapy.  Some damage is permanant.  Go with hormonal treatments, they can be more effective than chemo.

    My score was 12..I chose no chemo and moved on to having a complete hysterectomy and taking hormonals.

    I did kind of a pros/cons type list using my family history of cancers in general and the side effects (yes, some are VERY permanent) to make my decision. Since the chemo would have only added 1-2% benefit I chose to hold that in reserve in case I might need it at a later date...Heaven for bid!!!!!!!!!!!!!!!!

    I think we each have to make decisions that we are comfortable with then find peace with ourselves in our heart with those decisions...

    Im a bit over 2 yrs out now and just passed my last 6 month follow up dancing with NED(no evidence of disease).

    I do have thoughts sometimes about maybe I should have done this or I should have done that but all in all, Im comfortable with my choices and decisions.

    Best of luck and wishes

    I know you're in a tough spot.  My tumor was really the ame as yours but 1.2 cm.  My oncotype was a 15. Nobody 2 oncs or surgeon told me what to do.  They kinda kept saying that I had to do what I felt comfortable with in a week, month or year.   I am currently on CMF (there is a long thread).  I was told 3% additional reduction.  SE aren't bad on CMF and there has been minimal hair loss.  Tiredness is the worst part for me.

    I thought about TailorX, too to make up my mind but tin the end deciding against it.

    Good luck with your decision.  I know how hard it is.

    I know how you are feeling.  My onco score was an 18 and after talking with the doctor I elected not to do the chemo.  He told me the side effects outweighed the advantage for me.  Of course I was 58 and age plays a difference also over someone much younger.  I did not want any chemo as I knew to much about side effects and I was happy to walk away with the rads and hormonal pills.  I try not to look back and keep on going.  I willl go for my 18 month mammo and ultra sound the 23rd of this month.......

    lisalachelle, you can't be sure.

    Medicine is "applied" biology, and there is no sure thing when you're dealing with a biological system.  (Well, there are a couple of sure things, but let's not go there.)

    If it's any consolation to you, an Oncotype score of 14 would have had me dancing in the streets.  My mental "cut-off" was a score of 18.  Lower than 18 = skip chemo; higher than 18 = think about it seriously.  So, for me at least, 14 would have felt reasonably safe.

    The thing is, there is little point in "throwing the kitchen sink" at a tumor if you only get 1-2% benefit from the treatment and the chances of long-term SE's from the treatment are greater than that.  Why risk a 2% chance of heart damage or acute myeloid leukemia, if the benefit (risk reduction) from the chemo is no better?

    What you're facing then is a coin-flip:  heads, your tumor comes back; tails, you develop heart failure or leukemia or both.  Why toss the coin at all?

    Full disclosure:  the risks of heart damage and leukemia are mostly associated with Adriamycin, although Cytoxan does carry a somewhat similar risk of leukemia.  The long-term risks associated with the taxanes are supposedly lower, although I'll bet we'll know more in about 10 years...

    Hi lisalachelle,

    I also had an Oncotype of 14, but I did do chemo.  But, my tumor was 2.3 cm with other areas of DCIS.  Also, I had vascular involvement and necrosis, which means the tumor is growing fast enough that the blood supply dies because it can't keep up.

    But, if I was in your shoes and had no other complications, I would have skipped chemo with a 14 score.  Good luck in your decision!!

    Lisa, that's important information you've posted.  No two tumors are alike, even when they're the same size or carry the same Oncotype score.  With factors like yours, I'd probably have changed my opinion about chemo, too.

    Hi, Lisa ~  Congratulations on that nice, low oncotype score!  I agree with MAMHOP that if you have any lingering doubts, get a second opinion.  I would also add, depending on where you're being treated, if you haven't already, you might consider going to or sending your records to a comprehensive breast center at a major university hospital.  The reason I say that is, they see far more bc than most local oncologists or hospitals, so would be more likely to see any areas of concern about your situation or be able to fully assure you more than other docs who don't deal with as much bc and as many onco scores in a year.   Good luck ~  Deanna

    lisalachelle - All good answers! 

     I don't know if we can ever know that we did enough, except if we die of something else. 

     My onco is a chemo genius (I'm told), and he didn't recommend it for me.  However, when he saw how spazzed out I was, he ordered the oncotyping.  My score was 15.  His nurse called to say "WOO HOO!" - no chemo!  But, when I went to see him, I still wasn't convinced completely - 15 seemed high to me.  God only knows, I didn't want to leave any stone unturned, but he put my statistics into a computer which showed only a slight decrease in recurrence with chemo. 

    I hope I did the right thing by not having it.  I don't know how we can tell, but once you make the decision, then you embrace it and try not to look back, second guessing yourself.  Yeah, easy to say - I try not to.

    The Arimidex will help stave off the beast, I hope.  And, if my onco was wrong, I have reserved the right to go whop him upside his cute, little face!!

    Juliesmithson, I have heard and seen in other people that chemo can be very toxic. I wanted to make sure I was doing everything I could.

    What hormone treatment did you end up choosing?  For someone premenopausal I am not sure it I would get more benefit with ovaries removed then aromatase inhibitors or something like Tamoxifen.

    My onco hasn't addressed that yet- but I am curious.

    otter, Thanks so much for the reply.

    I have read some of your other posts too- and you sound very well read. It is reassuring to her that in your mind too the mental cut off would have been about 18.  I think so too. (of course their are individual considerations) I suppose once you feel you are knowledgeable or at least informed on a subject you have to rely on research that is available at the time.  

    I didn't know how to post my Dx correctly-my size is 1.8 cm and Stage 1 (but I didn't see a 1c option and it groups all 1-1.9 together as 1 cm I think) 

    Please feel free to give more input - I found it very helpful

    Lisa - my tumor situation sounds almost identical to yours and my oncotype was 19. My oncologist said that most people in my situation would not opt for chemo and that he was comfortable with no chemo but it was up to me. I went for a second opinion at Dana Farber In Boston and they very definitively recommended against chemo, saying that in my situation the risks of chemo were about as great as any benefit I'd get out of it.

    Kamico3 and all who have responded- It is so nice to hear from others who have been in a similar situation. The emotion of it I found to be such a roller coaster.  I went from feeling so happy, to feeling overwhelmed with the data and choice, to scared I was making the right decision.

     Up to this point it had been a constant struggle of waiting-then doing what the doctors recommended.  And I think cancer treatment has come a long way and become very individual.(with gene therapy which is amazing- yet it leaves the patient wondering if they did the right thing).  

    I would love to continue to hear from more of you who made this choice.  I think It puts a since of relief in all are minds and gives us some clarity to hear from others who made this scary and very big decision.

    Hi Lisa -  I was diagnosed with stage 1 IDC in April of 2005 at the age of 44. My tumor was very strong estrogen and progesterone driven.  I had the oncotype test done and my score was a 19. I utlimately (after lots of thinking and reading - and there wasn't near the information that is availble today -  this was before the TailorX trial was started) decided to decline chemo (with my oncologists' blessing), had a lumpectomy, full breast radition, a  hysterectomy and have been taking Armidex since Sept 2005 and doing well.

    It's a really hard decision to make. We have to weigh many factors and be comfortable with the decision we make -  there are absolutely risks with the decision to do chemo and risks with the decision to not do chemo.  We have to make a decision and then not second guess it.  That's whats' so hard ...  we don't know the outcome and don't know what will happen down the road. Where's that crystal ball when we need it ?? 

    Hugs and hope you can make your decision and move forward - and then not look back!

    I may be the odd one out on this one, but my oncotype was a 14 as well, and I elected to do 4 rounds of AC.  I consulted with 2 oncos, one at a major cancer center near me, and one in private practice.  They both felt that due to my young age (35 at dx), and the fact that I had multi-focal tumors (2 of them, though small), I would do well to choose chemo.  I was also concerned about the cut-off range of Tailorx being 11, and I wondered what that would mean for me.  Doing chemo was probably the hardest decision of my life, along with getting a mastectomy when my original lumpectomy showed bad margins.  BUt, I prayed, talked, thought, sought opinions, and in the end felt that I wanted to do whatever I could this go 'round. 

     BTW, my scores showed a 4-5% improvement if I did chemo plus Tam.  That was enough for me.  Maybe not for others, but for me, yes.  I have 3 little boys and I did it for them and my dh.

    After my last chemo I got the results of my BRCA test back and found I am BRCA 2 pos.  Now I have my ovaries to think about!  Made me feel reassured that I went ahead with the AC.  SEs were not pleasant, but manageable.  We can only make the best decision we can make, and pray its the right one.

    Best wishes!

    I decided not to do chemo with a score of 15 after discussing it with my onco, surgeon, family doc, and plastic surgeon--who has had cancer himself. All of these doctors that I trust very much said no chemo, and cited potential risks over benefits in my situation. I did have one onco say I should do chemo, but it didn't feel right for me.  I'm on Tamoxifen and I have decided to have my ovaries removed in April.

    Regarding the Tailorx Study the cut off numbers are arbitrary and do not mean the Oncotype numbers are incorrect.  It is most likely regarding statistics, by dropping their number down to 11 they will have a greater number of women in the "gray" area, resulting in the potential of a robust and defensible statistical out come. I've discussed Tailorx extensively with my onco and have a stats background, and I work for medical school and  research institution--although I am not a researcher, so I think it has to do more with research design than a flaw with the Oncotype numbers.  Even with knowing that I was frightened when I first saw the Tailorx cutoffs. It is a very vulnerable time for us.  I've learned that our treatment  is a very private decision and the best we can hope for is love and support from people in our lives as we make our decisions.

    To lisalachelle,

    Tamoxifen was what the oncologist told me to take, for five years.

    I had an Oncotype score of 15 and after much consideration decided to do 4 rounds of Taxotere and Cytoxan followed by the Tamoxifen.  I had one node that came back with a microscopic malignancy.  After talking with my oncologist who initially said that his gut was just to do Tamoxifen I just didn't feel good about it.  In my mind if my nodes were all negative I would have been OK.  I elected not to do additional lymph node surgery b/c it wouldn't change the chemo regime.  This is my second cancer.  I was diagnosed with Hodgkin's Lymphoma at 19 and at the time only needed 10 weeks of radiation after two major surgeries.  I just felt that I should do a little more than a pill and I didn't want to wonder if I did enough.  In my mind my 40 year old self could handle all this better than my 63 year old self which was the age my mom was diagnosed with IDC.  Along with my right mastectomy I elected to have a prophylactic left one just to be done with it.  I didn't choose reconstruction b/c I've had some many other surgeries and have a heart problem (heart failure not from chemo from pregnancy).  So while chemo was a concern due to my heart both my cardiologist and oncologist felt I'd fine with Taxotere.   I like EMILY2008 will take my 4% improvement for my daughter and DH.  I'm SO DONE with cancer and wanted to wipe out anything that "may" be thinking about misbehaving.   In the end,  you have to do what you feel is right for you.  Oh, and I prayed A LOT.

    BTW, so far after round one of chemo, it's not THAT bad.  I'm having some blood count issues (see my post Neuprogen) but after about 7 days of iffy feeling, no throwing up, I'm ok.   Good Luck!

    DoreenF- I think that is is wonderful that you got in on the early genetic testing.  And you are an encouragement to all of us that you are doing so well years out.  How did you decide to do a hysterectomy being premenopausal?

    Emily2008- It sounds like it is good you did chemo being BRCA 2 positive.  I too took that test and was at first not sure and scared to get the results.  Later I concluded that I should take it because I didn't want to walk around not knowing if I did have it.  It sounds like you have been through a lot. I might eventually have your ovaries removed so you don't have to worry about it.

    KEW-It was encourageing to see that your score was close to mine and you chose no chemo.  And I also really enjoyed your prospective on the TAILORx study and research.  How did you come to the decision to have your ovaries removed in April.  That is the next decision I have to make.  From what I have been reading I too think that there my be more protection from AI's but I don't know what I'll do. It is hard for friends and others to understand sometimes how not doing chemo is still doing all that is possible based on tailored information that is so personal and individualized with therapy now.

    juiliesmithson-glad to here you are doing well. (and it has been over a year-Yah)

    40baldboobless-Sorry to hear you had a 2nd Cancer. I can see how you would wonder if it was enough if you didn't do chemo since it was slightly in a node.  I am happy to hear your chemo so far is not too bad.  I hope it goes well for you in the days to come. Continue to dance and live life!

    lisalachelle - My decision to have a hysterectomy was due to fibroids - I'd had uterine fibroids for several years that caused extremely heavy bleeding - I was taking the birth control pill to control the bleeding  - my tumor was ER +++, PR +++ as was being fueled by the birth control pill ... so I had to stop taking that (obviously) -  my gyn had been talking to me about a hysterectomy every year I went in for  my checkups ...  so... my bc diganosis made that decision pretty easy.  I was premenopausal at the time...  there's always more factors that affect our decisions. 

    I can't wait for the TailorX study results to start coming in .. and wished I'd been able to participate in that study ...   I was too far out from surgery when the study was first announced.

    Hi Ladies.  At my initial onco meeting, the one I'm still working with, he talked about how biology trumps size and age, there are apparently two camps on this.  My tumor had many positive attributes suggesting that it was unlikely to have spread, although we never know, until something happens.  My onco and my bs were thrilled with my score and encouraged me to use Tamoxifen as my treatment. My bs is a brilliant female surgeon who is highly educated on breast cancer beyond just the surgical aspects, so her opinion was valuable to me.  I have a great team.  The first onco discussed chemo with me and explained that it has been observed in some studies (I am trying to locate the citations, I had them, but can't find them, when I do I will post them) the benefit from chemo was not that it was actually killing ER+ cells, but that it was suppressing the ovaries--and that is where the benefit was coming from, the cells were cut off from their "food".  He explained to me that ER+ cells can grow slowly enough not to be "noticed" by chemo since it hits cells that are fast growing.  He also talked with me about how in many countries in Europe the standard care for women in my situation is Tamoxifen and ovarian suppression or removal.  He said the success rates compare with the US who use chemo widely. He did say that he didn't think I needed to do ovarian suppression--I'll get back to this. I am not biased against chemo--once I was diagnosed I cut 18 inches off of my hair with the expectation that chemo was in my future, my mom died of breast cancer so I was going to be aggressive.  I did see a second onco who said I should do chemo, but couldn't tell me why and he admitted to having a chemo bias.  I had a very traumatic couple of weeks, did a lot of reading, and understood that chemo would only benefit me maybe about 1-2% and with the error bars it could have a negative impact. If your % recurrence is 9% and your derive a 30% benefit which most people think they are getting--you are only talking about ~3%.  The 30% that you hear about chemo improving survival is related to the % recurrence, not out of 100.  I hope I explained that well. For me personally, I don't want to put my body through that for such a small benefit. The need to be aggressive that I had in the beginning changed with the more I learned, for me being aggressive is the Tamoxifen and more surgery, for me adding chemo was beyond aggressive. I went back to my onco and asked how he felt about me having my ovaries out and he said he would support me and so I'm doing it in April when I'm having my implants/expander exchange.  I am using a oncological gynecologist, and I am now considering a complete hysterectomy.  We'll see.  This has been very difficult for my in the sense that the extent of my medical intervention in my 48 years has been tonsils out, wisdom teeth out, and two completely natural childbirths.  I haven't needed much done, don't take meds unless there is a good reason, so deciding to have more surgery really took thought.  On another note, I started back to work today.  Everything feels different.  Let me know if I answered your question.

    I think we tend to focus on the percentage gained by chemo (1-2%) and fail to see the flip side.  There is a 98-99% chance that it will NOT recur.  Doesn't that sound more encouraging?? To me, that is the better way to look at it.  Chemo is not without its risks.

     My score was 20 and my oncologist did not recommend chemo.

    This is amazing.  I was just in bed tossing and turning wishing I could find someone who opted out of chemo ( which is where I am leaning at the moment). I decided to come down and check this forum and here you all are having the very discussion I was looking for.

    I have had 2 surgeries.  On the redo we got clean margins but less than ml which is  below the comfort level of the team. Much to my shock they were recommending a  mastectomy and chemo.

    I have clean nodes and so far no evidence of spreading.  I have an MRI on Monday, and sent in the test today to see what my onco type is. I am in the 1c stage of ILC. Does this recommendation seem hasty?  I would like to go in for a better margin, and also wait to see what my score is. All these people are very poised, caring,  and I am sure have my best interest at heart but I am starting to question.

    I do have the type that can use Tamoxifen

    Hello everyone, thought I'd weigh in too.  My oncotype score was 17.  I opted out of the Tailor X study because I wanted to make my own decision.  I fell into the gray area where they randomize you into chemo/ no chemo.  When I asked my onco if he would recommend this for his own wife (assuming she had the same score), he said no.  However, he was very keen to enroll me!!  I think when all the results are in they are going to find that oncotype number is one small piece of the puzzle.  Tumor size, hormone sensitivity, histology (how cells look under the pathologists microscope), BRCA genes, and family history are all going to weigh in too.  I decided on no chemo in large part because of my breast cancer cell type (tubular) and family history (grandmother and mother had bc)-neither did chemo, both survived AND oncotype score.  Hope this helps.  By the way, I still question if I made the right decision.  But like everyone else here, you make the decision thats best for you and go forward.  Best of luck to you.

    Merilee- I will pray for you in this very difficult time.  It is a time of fear, waiting and uncertainty.  I anguished over the decision of chemo more than any other step along the way.  But I found some peace in first God, and then in knowing that I had to be an informed patient and move on with my choice.

    I was so pleased to hear this site was helpful to you.  I hope that many others as well will write in to share there experiences. I feel it is an important point in our treatment coarse-and that we can gain encouragement from others very much. It has helped me a great deal.

    This is a quote I read at the time that I found very helpful from Lillie Shockney, nurse at Johns Hopkins Foundation for Breast Cancer. She wrote:

    We all make decisions based on the information we have at any given moment.  BEING AN INFORMED PATIENT, keeping current with the latest in research, and taking steps to reduce our risk are the best-and only-ways to help ensure that we remain healthy.  There my not be one right treatment for any woman with breast cancer.  There are various treatment options that are appropriate from which to select.  Being informed enough to participate in the selection is the thing that will make your treatment the right treatment for you.

    I found that so powerful.  I now know that I am thankful that I can move on with hope, and thankful that God has lead me in this fearful path with the Hope of a Loving Savior.  I am also amazed in tests like the oncotype test, it gave me a new beginning and a point to go on from there and live life- whatever decisions we must make. 

    Please continue to write in with what treatments you chose, and stories you have after getting your Oncotype DX score.
