Help with Treatment Option!
Hi, I recently had a lumpectomy and my surgeon had submitted my specimen for both an Oncotype DX and MammaPrint. My Oncotype DX came back with a low risk distant recurrence rate (6% with hormone therapy) but my MammaPrint came back with a high risk distant recurrence rate (12% with both chemo and hormone therapy).
I went to my oncologist, she does not recommend chemo based on my cancer tissues profile (grade 1, stage 1, low Ki-67, high ER and PR, Her-2 negative, and no family history, BRCA 1,2 negative), she thinks my weapon is tamoxifen. Further, she seems to rely on the Oncotype DX more as she believes that it is a better test.
Then, I went to get a second opinion with another oncologist, she said she would not rely on the Oncotype DX as the test was validated with women who are over 55 (post-menopause). She would rely on the MammaPrint more which indicates that I have a high risk of recurrence. Coupled with my young age (34), she will just throw everything to me to give me the best prognosis.
Why is there such a discrepancy between the Oncotype DX and MammaPrint? Does anyone have any idea? Now, I am torn, unsure which way to go. I would love t o hear from ladies here and I really appreciate your opinion.

Hi TaiTai,
Welcome to BC.org. Sorry to hear about your diagnosis, but welcome to our forum. I've gotten a lot of helpful information and support here, and hope you will too. I'm sorry to hear you were diagnosed at such as young age. I was diagnosed at 46 and thought that was much too young, so I can't imagine what you're feeling right now. And to get conflicting advice from the two tests and two doctors--that must be super confusing.
I can't speak to your main question--which test is a better indicator. (my tumor was 5 mm and too small for the Oncotype test.) But I'll share some questions I would have in your situation and other thoughts, in case it helps. I'm not a doctor, so please don't take any of this as fact, but perhaps some "food for thought" or ideas to discuss with your doctors.
Have your doctors said how much you'll "benefit" from chemo? i.e. would it reduce your risk of recurrence from 20% to 12? Stage 1 BC doesn't benefit as much from chemo as Stage 2 or 3, because it's slow growing. I think my medical oncologist (MO) would give a similar recommendation as your first one. You and I have similar Dx, and my MO disrecommended chemo but strongly recommended tamoxifen. (BTW, I'm assuming you had a sentinel node biopsy and all the lymph nodes came back negative).
Your young age is a consideration, since you have a very long life expectancy. My understanding is that women under 50 "benefit" more from chemo due to their long life expectancy. To the cancer doctors, 50 is considered young, so when they see you they must think you're super young. (just an FYI on their perspective)
One thing I've learned is that doctors have their own philosophies when making recommendations. Some are conservative with treatment; some are more aggressive. Some want to offer every possible treatment. Sometimes the age of the doctor influences his/her philosophy too. (but not always) We patients should consider our own philosophy too. Are you the type of person that wants a lot of treatment or little? Would you feel better knowing that you've done everything possible, even if the Tx might be overkill or perhaps create side effects? There is no right or wrong, just what is right for you. For example, when I chose to have radiation treatment, there were several options. In my case, I wanted the one that would have the least risk of damage to my bones; the choice also had the longest track record, which was also my preference. But some patient prefer the latest-and-greatest or have other considerations. You can decide what's important to you.
Do you have a cancer support center near you? Mine had free counselors we could talk to. They won't advise you on the choice of treatment but might help you sort out the surrounding emotions so you are clear in your decision. When I talked to my counselor she said it's hard to make these decisions because we don't know what the future will bring. She said the goal--ideally--is to be content in your decision no matter the outcome. So the question is, how would you feel based on the following scenarios: if you decline chemo, and then have a distant recurrence? If you choose chemo and never have a recurrence? (you might also choose chemo and still have a recurrence; or you might decline chemo and not have a recurrence. No one knows.)
I'm not sure if any of this is helpful. But please know I'm thinking of you and will be sending warm thoughts are you consider this and make your decision.

Hi Peggy,
Thank you so much for taking the time to share your thoughts with me, I really really appreciate it. I guess ultimately, I have to decide what is "right" for me. I mean I can keep researching and seeing more doctors, but the bottom line is I think there are way too little data on women like us (pre-menopause). Since we have smiliar diagnosis, if I have more concerns/questions (which I am sure I would), would you mind sharing your experience with me? Thanks.

It is really hard to make these decisions. I thought I was young at dx (age 45) but you are far younger than me. Whatever you do, make a decision you can live with - with no regrets. I had only a oncotype test and my score was 17 which is the highest number in the low recurrance category. I also had angiolymphatic invasion present in my pathology. This REALLY scared me. It scared me enough to have the chemo. The other reason I chose chemo was because I have a young child (my son was 4 when I was DX). I wanted to treat things aggresively to be here to raise him. I also knew I could use cold caps to keep my hair through chemo and maintain my privacy. The caps allowed me to go through treatment without other people knowing and it allowed me to not have to tell my 4 year old son about cancer or chemo (I will tell him when he is older).
I am in no way telling you that you should do chemo. This was how I made my decision. I am glad I did the chemo. I know I did everything I could to beat this. If it comes back then I will know there is nothing else I could have done.
You may also want to review the NCCN guidelines for treating BC for your diagnosis and age. Often younger women do get chemo automatically just because of age. If you are not sure, get one more opinion. Maybe it will help you make the decision.
Best of luck! Hugs!!

Hi TaiTai - congrats on lx&snd over and healing. Waiting & decisions...oh our choices ugh this c:(
You've received great input to consider.
Does your medical center have a BC support group or oncologist social worker? If so go!
Visit, scheduled an appointed, talk, listen...there is no right or wrong choice of treatment. We are all different are cancer are different there are so any variables...but there is a what is right for you in your heart and gut! You will know it will bring you peace and never look back or second guess yourself.
Talk with your mo on benefits and risks of chemo...my mo did not advise. Risks too great. Since my mo came highly recommended by family friends and I heard encourage stories from BC support group...and noted that everyone's tx plan unique for them I had absolute confidence.
Moving forward not looking back.
Ask ask ask then move forward when you are comfortable with your plan of attack!
Sending calm confident thoughts and prayers! You got this brave warrior!
Join us in the lumpectomy lounge!
(((Hugs)))

I would ask that your case be presented to the tumor board. That way, you will get many opinions.
Furthermore, annicemd started a thread Premenopausal, Stage 1, Grade 1, which I think is worth reading because there has been quite a few of us with similar tumor characteristics. I was premenopausal when diagnosed, but two decades older, so my treatment decision was a little easier.
I wish you well. -
Thank you ladies for all the great suggestion. Definitely felt the kindness and support from all of you. I think I will ask my oncologist to present it to the tumor board and see what they say.

TaiTai, yeah, you're right. There's definitely not as much data for pre-meno women, which can be frustrating. And I see your tumor was <1 cm, like mine, which is on the smaller side of stage 1. (so, in theory, the risk for a typical stage 1 patient might be a bit overstated for us. But to be honest, at some point that feels like splitting hairs, since we're all trying to guess an unknown outcome.)
You definitely sound like you're in a much better place mentally than I was when making those decisions. I kept thinking if I only did more research I'd somehow find some magical answer and everything would fall into place. ha.
So, at the risk of introducing another piece of data (!) there's a website called cancermath that lets you look at possible outcomes with and without treatment.
http://www.lifemath.net/cancer/index.html
I'm an engineer so I wonder how they do their calculations, but maybe it can provide food for thought or conversation for your MO.
Sure, feel free to send me a private message if you'd like. I sometimes check the boards in waves (i.e. when something is up for me).
voraciousreader, had an excellent suggestions with that other thread: " Premenopausal, Stage 1, Grade 1". I don't know how I forgot that.
Anyway, I'll be thinking of you at this point in your journey. Rest assured that once you do make a decision, it will be the exact right decision for you, no matter what you choose. And...I hope you're able to get in some "distraction therapy" this weekend (go outside and do something fun, and not related to BC). Take care.

Thank you for all the support and kind words. @ Peggy, I will definitely check out the recommended website, thanks.
So I ended up emailing my oncologist for my concern about her reliance on the Oncotype DX even the test was validated by mostly post-menopause women, and I decided to post part of her response below... I think it will be helpful for ladies who are also curious.
"National Comprehensive Cancer Network/American Society of Oncology publish guidelines as a general guide for oncologists. They recommend using oncotype dx to help in making a decision in women with tumors larger than 1cm that are lymph node negative and ER positive. They do not recommend Mammaprint as studies using mammaprint to predict response to chemo are very small and not validated.......Oncotype Dx has been shown in lymph node negative, ER+ women, both pre and post menopausal, to predict prognosis and value of chemotherapy. Mammaprint has been used on a variety of tumors, including the above, and can predict prognosis in some but unclear whether it can answer the question of who benefits from chemo. This is why Mammaprint is not FDA approved for this indication, while OncotypeDx is."
