Onchotype Dx test

Options

I'm curious how many women here have taken the Onchotpye Dx test before receiving chemo.  My Dr. reccomended it and I receive the results in 2 weeks.  I'm just wondering how often the results come back less than 20 and people choose not to have chemo.  I'm praying that my number comes back LOW and I can skip the chemo!

    Hi

    just wanted to answer you--the test is designed to be taken before you start chemo-since it is meant to help you make a decision about whether or not you should have chemo...

    Not sure about the stats--people get low scores and still choose chemo or high scores and dont' take chemo--it is really your decision and the oncotype is just one more piece of information, along with your dx, your current physical health, your family situation--- all that come into play.

    I think the hardest part is when the score is squarely in the middle range (happened to me).  In the end, you have to make  a decision you can live with---- I chose 4 rounds of chemo and have never regretted it...

    good luck-hope you get a 0 oncotype!!!

    Mine came back at the low end of the middle range.  And the state of the art doesn't even know with clarity where the low range ends and the middle range starts.  So there's a real possibility that I am already in the low range, in which case, chemo would not be recommended..

    So my decision: no chemo for me.  Instead of spending this year choosing to be sick and miserable in the hopes that I'll live another decade without a recurrence,, I'm going to spend the year getting well after last year's hell and be as healthy as I can.  If I have a recurrence, I'll address it then.

    My OncoType RS came back at 30. Decision fairly easy. Chemo moves my chances of preventing recurrence to 86% from 79% with just hormonal antagonists. I'll do it. But which one? Onc recommended TC, to start past Monday. Researched all weekend, and learned there could be  a rate as high as 6.3% of permanent hair loss with Taxotere. Cancelled appointment. Learned CMF has fewer SE's, asked to go on CMF. Onc refused, saying it did not meet standard of care. I've asked for 2nd opinion, but am worried about time line. It's 9 weeks since lumpectomy. Would love to to know if anyone has any advice.

    Consider that not everyone experiences all or any of the side effects of a particular medication. Consider also it is mostly those experiencing side effects that speak out. Talk to you onc about why he recommends one treatment ovr another.

    I had a 19 oncotype and a mammoprint of low risk so my onc said I didn't need chemo. I'm on Tamoxefin (anti hormore but also considered a chemo drug) for 5 years.

    Jan,

    I had a oncotype of 9 and did lumpectomy, rads and four years of Tamoxifen.  Now I'm back with ILC in the same breast and same location.  Now I'm doing chemo and bilateral masectomy.  I wish I would have done more the first time.  I hope your plan works out better than mine did.

    Take care,

    Nancy

    My oncologists ordered the test when I made my first appt and had it back by the day I went to that appt.  I had a BMX so no rads, and my oncotype was [8] so no chemo.  I'm on Arimidex for 5 years. Hope you get a great report.

    mamie65 - hair loss was a major concern of mine as well with the TC so I ended up using penguin cold caps and kept all my hair. There's a huge thread on here if you are interested. It's a big hassle and a little expense (not much more than a really good wig) but well worth it in the end.

    IllinoisNancy - the Oncotype Dx test is a predictor of distant recurrence, not local recurrence (which is what is sounds like you have) so don't be so hard on yourself. Good luck with your future treatment.

    HI, I also had the Onco test as my Tumor was ER+, Pr+ and node negative. The Oncogene test specifically helps women like me have another piece of information to decide about chemo. I was given a 13% benefit from chemo and given all the side effects didnt think it was worth it.  I did 37rounds of radiation, 29 regular, 8 boosts and now on arimdex. Which I had to just stop taking these past two weeks due to some issues with my heart rate.  They are likely switching me to aromisin once my heart rate normalizes.  Good luck on your decision. I saw several Oncologists for opinions before I made up my mind. I highly recommend that!

    My oncotype was 9. The oncologist was already leaning toward no chemo, and that cinched it.

    My score was 17 and as I am 59, the 2-3% extra benefit chemo would give me was not worth the 4-5% chance of permanent side effects for me.

    My oncotype was 27 with an ER, PR lobular tumor.  I had a mastectomy in December and the edges and nodes were clear.  Am just starting CMF.  The onc did not want to give me AC because A can affect the heart.  I will have 8 treatments, 3 weeks apart.  Just trying to prevent another recurrence.  I had a mastectomy 10 years ago with DCIS, Her2Neu.  Was on arimidex for 7 years, and had my recurrence while on it.  After chemo I will be on tamoxifen.

    mamie65,

    I've postponed chemo, and have yet to start it because I wasn't comfortable going ahead with it.  I had my surgery late Oct.   I feel like Pompeed about the benefit not being worth the bad SE effects I could end up with. I had a low end of the middle range score of 20. But then I had a positive node so my onc strongly suggests doing the chemo but also doesn't want to do CMF.

    As far as I can tell by research I read...the difference in chemo regimens may only apply to certain groups of women.  Older, post meno ER+, PR+, Her2- women may even do better just doing hormonal tx.     I've been torn up about this for weeks trying to decide what to do.  All I can say is keep reading and keep asking questions about your particular case.

    Hi Lee, have you thought about getting a couple of Oncologist opinions.  I saw 3, and doing this really helped make my decision.  Good luck to you.

    I got a score of 15 and my onc recommended no chemo, and so did I! Thought risks greater than benefits.  It's all a crap shoot really.. and nothing is guaranteed... but you make your decisions based on what information/technology is available to you at the time.. and something that feels right for your personal circumstances! 

    I hope you have a low score and are able to make a clear decision! :)

    I did the Oncotype DX test and my score was 17. I chose to do chemo despite my lower score. I am 32 years old and have a 5 year old daughter and felt that 4-5% in risk reduction was worth it, because I felt I owed it to myself and my child to do everything possible to lower that risk.  Also, I had a talk with my radiation oncologist and he gave me some helpful info. on the study done with the oncotype dx test. First it was done over twenty years ago. Second, the participants in the study were in their 50's which is when breast cancer normally affects women.  So the study is not necessarily applicable to women who were diagnosed young.  For whatever reason breast cancer in younger women is more aggressive and I feel that I have a long life ahead of me where the cancer can return.  So, I wanted to take every precaution.  Even though my cancer was Stage 1 with a low oncotype DX score, I also had 3 separate tumors.  Either way, I chose to do chemo and it really sucked, just hope it means no recurrence for me!
