Topic: use of oncotype dx test on node positive idc

There is a stage III clinical trial(RXponder trial) that is currently recruiting women who are node positive & have oncoscores low to intermediate(I think). There have been smaller studies & there is some data to suggest that oncotype testing can be used on node positive women. I had to ask for the test 3 times before my MO agreed. I was ready to shop around for a MO who would order the test for me. Not sure how stongly you feel about getting the test but you might want to consider participating in the Rxponder trial. I wasn't able to. My onco score was low with 2 poitive nodes & I ultimately decided against chemo. Very hard decision.

My MO ordered the test and even with 2 positive (micromets) nodes she said no chemo. Oncotype Score was 14. I am also 63 with a low grade tumor.

Hi  I received my oxy score and was hi risk for recurrence my score 35.  Taking the chemo will reduce my risk by 12 %.  My score said I had 24% recurrence.  That is to high for me and also a significant inmprovement.  Initially I was told probably no chemo just RAD with a lumpectomy.  My IDC stage 1 grade 2 SNB with no cancer cells in eigther node.  My cancer is ER pos PR Neg and Her Neg.  Generally oxy score are for those with no lymph node involvement and stage 1 or 2.  I would highly suggest that oxyDX be ran if possible.  I start my chemo journey on 6/12/12 this coming Tues.  I do not look forward to chemo but I am so thankful that my onco ordered it because I have made the wise decision to have chem.  I will also have RADS after chemo for about 6 weeks, then on the chemo pill for 5 yrs. The test is geared for your specific cells and onco can treat you with the right therapy for you.  If your insurance pays for it then have it because test the tumor itself after removal. Good Luck to you and all of us.  I intend to fight this fight with all that I have and stay positive!!!  No looking back at my Onco and my decision, just forward to live a long and healthy life. Hang in there, I will!!

Yorkie Mom posted about age but if oxy score came back at 14 that is pretty low risk for recurrence. 

also I believe the micrometastis is considered node neg.  If my oxy score were 14 I probably would not have chose chemo and I doubt if my Onco would have given chemo. In this case it would have nothing to do with age 63.

Geeze  I must be anxious about chemo on Tues., I can't get my brain and fingers to get togther.  I posted that yorki mom posted age but it was Wilrumara.  I stand corrected again...  oh well have the test.  keep us informed.

scaredycatwoman - First off, are you ER+ and HER2-?  If both, then the oncotype test can help you.

If ER+ and HER2-, I'm guessing that one MO is dismissing the need for the oncotype test because you are grade 3 and have node and lympho-vascular involvement.  If your onco came out low intermediate or mid intermediate, the node and lympho- involement would likely push the scale towards chemo.  Since you are grade 3, it is very unusual for the scores to fall into the low-intermediate or low range.  Very likely the MO sees chemo as necessary and the onco score wouldn't change that.  That MO might also be considering what % your ER and PR are and how effective homone receptive tx will be, as well as other results in the pathology report.  

The other MO might want to see the range in which the onco falls to help guide the type and number of rounds of chemo you might receive, and maybe hope the score will be low enough wouldn't need it.   

Even though grade 2, I could have skipped the onco because my PR was very low and Ki67 very high.  It was pretty clear it would score at least mid- high intermediate.  Did it anyway and is one point below high risk.  Because I know how high my recurrance risk is, it's always in the back of my mind helping push through all other treatment and other activities that will help prevent a recurrence.  It's a useful piece of information to guide you for the rest of your life, not just to decide on chemo.

I'd definitely push for it.  It's another valuable piece of information you can use to make decisions.

P.S. Scaredycat, you'll see from my signature that my DX was quite similar to yours...grade 3 IDC with 1/3 positive nodes. I'm technically a stage 1b, to your 11a, probably because of the size of the tumor.

I'll be happy to help you with any info that can help you. Alas, I'm not in your region of the country and can't recommend docs.

Copied this from this site about the stage.

Stage IB describes invasive breast cancer in which:

• there is no tumor in the breast; instead, small groups of cancer cells - larger than 0.2 millimeter but not larger than 2 millimeters - are found in the lymph nodes, OR
• there is a tumor in the breast that is no larger than 2 centimeters, and there are small groups of cancer cells - larger than 0.2 millimeter but not larger than 2 millimeters - in the lymph nodes.

I'm a stage 2A, because my positive node was 3mm.  I guess they have to draw the lines somewhere, right?

I agree with Doxie, getting the Oncotype is another valuable piece of info and it helps confirm what your path report says.

scaredycatwoman,

I should add that I did ask to have the Oncotype done after they discovered my node was positive.  My score came back a 20,  13% risk and I didn't have chemo, just had rads and then on the AI, Arimidex.  I was glad to have the score to help with the decisions.

And like Coraleliz said, its a very hard decision.

My diagnosis was very close to that of YorkieMom.  I had 2 positive nodes (axillary), had an oncotypeDX score of 14.5, so no chemo.   I'm a person who has always reacted very harshly to any kind of medication/chemical, so I was really worried about chemo, and overjoyed at it not being "required" due to the result of the oncotype test.  On occasion I've been worried (of course) about recurrence but I doubt that I'd be less worried if I did chemo...  (I'm a bit of a worry wart)

My path report was very ugly. 12 pages of ugly. My MO did the onco dx after my lumpectomy with 4 positive nodes. My score was a 6 despite the 12 pages of cancer in all the tissue they took. 3 weeks later I had a double mastectomy and that report was just as bad. I am doing CMF chemo despite the low onco score because they took 14 more nodes when they did the mastectomy and all were positive for a total of 17 out of 17. My Mo said I could said I could very well be doing chemo for nothing based on the Onco score. I was too afraid not to do something with so many positive nodes. The chemo is not as bad as the fear of it. I am starting to shed some hair which is freaking me out. I do 14 days on and then 14 days off for 6 rounds. I researched cmf verses other chemos and the long term survival difference was only 1-2 percent with a lot less side effects. I don't know if I am doing the right thing and I don't believe any of us know for sure what is right.

I wish all of you the best in making your decisions.

Dianarose, For what it is worth, I think you made the right decision to do chemo. Once I learned that I had one positive node, I felt like I would never feel safe until I did chemo. The experience was not nearly as bad as I feared.

coraleliz- I wasn't offered the cmf either. I did my research and told the MO that't the one I wanted to do. He said he would back up my decision. I wish we all had a crystal ball.

Is anyone here participating in the clincal trial mentioned above? I had 1st post-surgical appointment with my oncologist today and brought up a clinical trial I am eligible for. The name on the consent form is not RXsponder but it sounds very similar, testing chemo vs no chemo on women with 1-3 positive nodes.

@lee7, after looking around on the OncotypeDX website I found that the trial mentioned by my onc is the RXsponder trial under a different name, and you are correct, it is run by SW Oncology Group (SWOG). I have decided to participate in the trial. I have also started looking for other trials that preceded this one, and found a list of abstracts on the OncotypeDX website. Some of those show no benefit to chemo for patients with low Recurrence Scores, even if they have positive node(s), but it was using a different chemo regime than my onc said he would suggest if I end up in the chemo arm. I want to see if any studies were done using that type of chemo, but haven't searched yet. I will report back when I get the test results, but that will likely not be until week after next, because of the holiday next week. And, I no longer need to search for a tissue bank, because another aspect of the study includes storing samples for use in other research projects.
