Thank you for explaining the oncotype DX. I didn’t have it done even though it was encouraged by my oncologist and surgeon. My diagnosis was HER2- estro+ pro neu. Grade 1 and 2. Took genetic testing and no braca 1 and 2 gene. Stage 2 cancer. I am on anastrozole. It was my choice and I feel comfortable with the choice I made. My health care team are amazing people in Honolulu, Hawaii!
We're so glad you found this video helpful and appreciate you for sharing your experience with the Yerbba community!
I had the OncoType test done and grateful I scored lower than 26. No chemo was a relief and now have undergone 21 radiation treatments with 10 more to go. Grateful for the excellent care from the team at Hoag and looking forward to living my best life ❤
Wishing you the best!
@@yerbba Thank you. I’m done but had to cut radiation at 21 due to severe burns along my collarbone area. Slow to heal and am disappointed I couldn’t complete the treatments but had no choice. Aromatase Inhibitor will begin in February.
I had the Oncotype DX test done and scored a 13 on it. I was so relieved not to have to undergo chemo though I was hyped up psychologically to do it if medically necessary. I think it is a very important test to ask your chemo doctor to order for you. I just had to do 30 days of radiation. Thanks to all the wonderful medical folk who helped me in CA and now in OR on my cancer journey.
Thank you for sharing your experience with Oncotype DX testing. It's indeed a valuable test that helps tailor treatment plans based on individual circumstances. Thank you for watching!
I scored 38, so I'm currently on week 5 out of 20 weeks of chemo. I'm not thrilled, lol, but I'd rather a 10% chance of recurrence over 26% without chemo. Grateful I had the test done. Thanks for discussing this.
We appreciate you sharing your experience. Sounds like the results of the OncotypeDX assay were super helpful in your case. Thank you for watching.
Hello I scored a 36 and I am about to start chemo. If you don't mind me asking how was chemo. I am a little scared of what to expect.
My Oncotype DX score was a 6, which informed my medical oncology team that I would not receive a benefit from chemo so I didn’t have to do chemo (yay) but that score plus all the tumor pathology reports also made me a candidate for accelerated partial breast irradiation (APBI) so I only had to have 5 radiation treatments rather than the 4 weeks. That too was a great outcome from the Oncotype DX results.
Now it’s Anastrozole for the next 5 years, and then we will see what’s next after that!
It's wonderful to hear how the Oncotype DX test provided such valuable insights for your treatment plan, leading to a path without the need for chemotherapy and a more focused radiation approach. It is the goal of cancer clinicians to give less rather than more. So happy to hear you've benefitted from "de-escalation."
I kept hearing about this test. Thank you for explaining it.
Thank you for watching. We're glad it provided helpful information about the Oncotype DX test.
I scored a 35 and received chemotherapy. My oncologist explained this to me but not as clearly as you just did. Thank you for your informational videos.
We're glad to hear that our video provided a more detailed explanation for you! Thank you for watching.

Hello dr. Jennifer , interesting video as always…I have a question I hope you could answer: what is your opinion on integrative treatments such as high doses of vitamin C, mistletoe or melatonin…do they work well in synergy with traditional treatment as far as improve the patient conditions? Thank you very much in advance.
In general, these treatments have not been tested. They are supported with anecdotes. While people's stories are important, it is difficult to recommend anything that has not been rigorously tested.
My diagnosis was High Grade Ductal Carcinoma Insitu & Invasive Breast Cancer Stage 1A tumor size 1/4 of a centimeter but contained the deadliest of cells which brought the Evasive breast cancer diagnosis. Oncodox score 37
BRCA2 gene mutation discovered at 50 yrs old Also Pagets Disease of nipple
PR-, HER2 -, ESTROGEN LOW POSITIVE 5%
Treatment done
Double Masectomy
Ovaries & Tubes removed
6 Rounds TC Chemo
Now on 3 rd aromatese inhibitor
Because first two were intolerable with all these why are estrogen blockers needed if mine was only 5% estrogen ? I understand that my cancer type the low estrogen breast cancer is least studied but what is known is it tends to respond as triple negative .
I’m having such hard time with aromatese inhibitors I just want to know risks if I stop them ?
Thanks for writing. You've been through a lot. With a low level of estrogen receptors, you are correct. The benefit of anti-estrogen therapy is very low. Talking over your experience with your medical team and expressing your desire to stop your endocrine therapy is a good first step.
My Oncotype DX came back at 46%. I did 4 rounds of TC and 30 rads, after DMX.
Thank you for sharing your story here with the community. Wishing you the best.
Hi Dr Jenn.kindly give more info of breast cancer stages eg 2A,2B etc
Check out our video on the treatment of Stage II (2) breast cancer: ruclips.net/video/tRSDpW3Zlec/видео.html.
Hi im 50 years old i have a lobular breast cancer 6cmx5cmx5cm er and pr at 95% ki67 at 10% her2 at 0 i have done a mastectomy and one sentinel lymph node removed showed micromets my oncotype is a 10 and i dont need chemotherapy now i undergo 25 sceances of radiotherapy then hormontherapy
Thank you for reaching out with your question. Managing lobular breast cancer requires careful consideration of various treatment options. It's hard to determine your treatment plan without knowing the unique characteristics of your tumor, pre-existing conditions, and overall health.

Very useful topic! I valued the input from my Oncotype test. It was a bit stressful to wait after surgery to get the results in order to make the chemo decision but understand the need to test the tumor. My result was below what would recommend chemo post menopausal. It showed
The recurrence score is extremely accurate. Recall that tumor biology (personality, which the OncotypeDX test helps define) is as important as stage.
Can they do this test on someone who has had a pCR at time of surgery as there is no tumor so to speak. Assuming you had neoadjuvant chemo. Or is this something that would be done at biopsy time? Thank you...
In someone who has had a pathologic complete response to chemotherapy, there would not be much value of the OncotypeDX assay. The benefit of the assay is in identifying people who will benefit from chemotherapy (+/- targeted therapy), which clearly you did, and in estimating prognosis. Having had a complete pathologic response is excellent prognostic information.
2.7 cm invasive ductal carcinoma right breast. 1 positive lymph node. PERI-menopausal with FSH @ 6.6 and Estradiol @ 443. Oncotype score @ 19. I'm worried b/c I am NOT post-menopausal so is my score low-enough to forgo Chemotherapy?
You're in that in-between spot. Talk your choices over with your oncologist because at this point, your preferences will shape the type of treatment you are offered.
Are you referring to staging under the latest AJCC 2018, (American Joint Cancer Committee) because originally I was staged at 2B, however under the AJCC 2018 I was 1A
Yes, we are using the AJCC 2018 staging system.
Is it possible to request this test 6 months after a mastectomy if the tumour has been stored in pathology. In UK I believe the tumor samples are sent to the USA. I was not offered this here after a mastectomy (second primary) in same breast Stage 2 grade 1 no lymph involvement but feel on all evidence it may be worth it ? Papilliary solid invasive 7mm
Great question. Papillary cancers have a low risk of recurrence. The OncotypeDX test is not used in this type of cancer because chemotherapy is known not to benefit the vast majority of people.
What do you think of 70 gene mammaprint? That’s what I received. Luckily mine came back ultra low risk. I don’t hear much about Mammaprint.
Mammaprint is another assay that is used in many practices. We'll do a video on the other genomic assays soon.
@@yerbba thank you!
If you have positive lymph nodes , but have a low oncotype score what needs to be the choice of treatment
Good question. If there are 1 to 3 positive lymph nodes, a low OncotypeDX score may lead your medical team to offer endocrine therapy alone and not chemotherapy.
Why do you get the test results after you’ve already had surgery? I had a lumpectomy after dx. After surgery the test came back showing an Oncotype score of 32. So, I then had chemo and radiation. My thoughts are IF I knew before the lumpectomy that I had a high oncotype score I might have opted for mastectomy.
You probably get results after the surgery because the test is performed on the tumor itself which would have to be removed first before being tested. That's my understanding anyway.
@@same5952 I probably don’t understand the biology part. When they did the biopsy that showed cancer is that sample not large enough to be tested also to give the oncotype score? It’s just that now I know I have a high oncotype score and would have felt better to have had the mastectomy instead of just the lumpectomy. 🤷🏻♀️
My surgeon told me that exactly. The biopsy isn’t a large enough sample for an Oncotype test.
The OncotypeDX test is not done in people with more than 3 positive nodes. So surgery has to be done to see what stage the cancer is. For our other viewers, the OncotypeDX test is not (yet) used to make prognostication or treatment decisions about surgery in invasive breast cancer.
My doctor sent the biopsy for the oncotype test. I had a bilateral mastectomy and then waited for the results. When my doctor finally called with the results, I was elated to score 13. No chemo and no radiation for me.
When did oncotype dx testing become available? And why does stage 3 er+pr+her2- not qualify for this testing ?(i thought Dr. Griggs indicated it was only done for Stage 1 and 2) I'm just interested if it was available in 2010 and I was not informed regarding its availability.
Oncotype DX testing became available in the mid-2000s and was in more widespread use in approximately 2008 for people with 1 to 3 positive lymph nodes. It’s used for early-stage breast cancer (stages I and III) and not for stage III because the risk of omitting chemotherapy in people with Stage III cancer high enough that consideration of omitting chemotherapy is not at play.
I am postmenopausal, recurrence score was 21 with a 7% recurrence rate within 9 years.The cutoff was 25 for chemo so I only have to take an aromatase inhibitor. With the score being closer to the 25, would you think that staying on the AI for additional years after the 5 yr mark would be beneficial? Thank you.
Great question. The cutoffs that are used are more helpful for estimating the benefit of chemotherapy (if any) rather than identifying whether or not 10 years of endocrine therapy is warranted. It may be that tamoxifen is offered for a couple of years up to a full 10 years total so that you get some benefit to your bones and liver from tamoxifen. These are all things to talk about with your medical team.
My surgeon refused to do a OncoType. I'm triple positive grade 2 stage 1. I have never understood why she did that. I'm postmenopausal. Do doctors refuse to do these test??
I could be wrong but I think the test doesn’t work on HER2 positive, only HER2 negative. Mammaprint works in both so I’m told. But Dr Griggs would be the expert on that.
This video says the test is done when your HER2 is negative, not positive. That's likely why, but you should be able to discuss it with your surgeon. Good luck!
For Triple positive breast cancer, chemotherapy is the standard of care. Oncotype is used in the case of ER +/HER 2 - to evaluate whether chemotherapy will be effective.
In people whose tumors are triple positive (ER, PR, and HER2 positive), the OncotypeDX assay results will always be high. Our video explains that the test can only be done in people whose tumors are HER2-negative.
Thank You So much for the video, also please let us know how accurate are these tests.
Also for the viewers from India, there's a homegrown test called CaNAssist, can we also get some more information about that if possible like the accuracy and success rates of these tests. Thanks
The OncotypeDX test is extremely accurate. Exceptions are if the tumor is widely heterogeneous, having different characteristics throughout. We are not familiar with the homegrown test in India. We can definitely do a video on such tests and other genomic assays. Thanks for writing!
@@yerbba Thanks for the reply :)
