Concerned about the side effects of anastrozole

Posted by tinalove @tinalove, Jan 31, 2016

I completed all treatments for breast cancer but now I am supposed to take hormone blocker, named anastrozole. im concerned about the side effects. Has anyone here taken it and did anyone have hair loss?

Interested in more discussions like this? Go to the Breast Cancer Support Group.

"My Oncotype score was also 8, so no chemo. And my risk at 9-10 year recurrence is 10%.:"

I've seen the results of seversl OncotypeDX tests and I've never seen a result where the risk of recurrence is higher than the Recurrence Score. Are you sure that you're not conflating the Recurrence Score (which is a number) with the Risk of Recurrence, which is followed by the % sign on the report (and assumes one takes anti-hormone therapy)? If you are noting the correct numbers, could this be because two different tumors were tested?

As an example my Recurrence Score was 9 but "risk of loco-regionsl recurrence....9 years" was 3%.

Buy they really should use less similar names for the two results as the majority of customers' calls are about the confusing terminology.

Yes. The recurrence score was 6%, but the oncologist wrote down 10%. The cancer was bilateral and it was everywhere, but very early stage like an explosion (don’t even go there…because I always had my routine screenings…it’s a story ).

But it will all get sorted out at my appointment. But I am curious if they will discuss the Breast Cancer Index test.

Thank you. My Oncotype score was also 8, so no chemo. And my risk at 9-10 year recurrence is 10%. My tumors were grade 2 and 3. I don’t know if they will do the Breast Cancer Index test to see if AI will continue or to try to determine risk of late occurrence.
My guess is I won’t continue because my oncologist said I only had a few more months to stick it out. But knowing there is a five year test is new to me. But baby steps! First step, MRI with breast surgeon. That has to be clear first, after which I will reconfirm what all my numbers meant when I see my oncologist and will also ask about this Breast Cancer Index test. I would like to have it done even if his plan is to discontinue the AI.

My doc didn't know about the BCI three years ago but it is now NCCN approved. I had to bring it to my doc and tell them about it 🙂

Yes, I read that! And coincidentally, my surgeon’s office just called to tell me something and I asked about this test and she said hopefully, the doctor who will do my clinical exam before the MRI will know something about it. 🤞🏻

I had a score of 8 and risk of 10 year recurrence was 6% with tamoxifen only. I assume my risk was close to 12% without meds. (At the 5 year point, the Breast Cancer Index test indicated no further benefit from my AI. Risk of late recurrence 5.7%).
ps I was either grade 2 or 3 and not sure how that affects risk score. I thought everyone with a score of 8 would have the same risk but @callalloo has the same score but lower risk at 3%.

I struggled with side effects initially but now I seem to be tolerating it well. I think my issues were enhanced by also stopping Bio-identical hormones 5 months earlier. A lot of changes all at the same time. No hair loss. My issues were joint pain, hot flashes, and emotional imbalance.

I did not know about the Breast Cancer Index test. I looked it up and they need to use preserved breast tissue? Oncotype was done immediately after surgery. This test would be done now and give a different type of result? While reading about it, I learned that it tests the activity of 11 genes.

At the time of my first year check up, my surgeon put me in a genetic trial (My Risk) to see if there were genetic factors that contributed to my original diagnosis. There were no mutations for breast cancer. I have 1 mutation that has not been determined to be benign or pathogenic for breast or ovarian so it’s a “variant of unknown significance”/ VUS. I was told I would be contacted immediately should more be determined about the variant in the future. Breast tissue was not used. It was a blood draw.

I will keep this in mind as one of my questions in July.

I will be going for my 5 year evaluation (since surgery and beginning treatment) and I understand that when we have our discussions here, it’s anecdotal information with helpful links. But it’s also been very helpful in that I am starting to prepare my questions for my evaluation and I am not quite confident about what my oncologist will advise and we are assuming that my exams and MRI will all be clear.

What did strike me in our discussions here, was all the info about the OncotypeDX. It prompted me to look at my score because for me, emphasis was placed on one score that determined that I would not benefit from chemo at my early stage. However, I looked at my other score/percentage for recurrence and it was much higher than others here who had my same number and talked about it here. (For example, if someone also had an 8, their recurrence was 3-4%.)
So some of my questions, if they aren’t addressed already by the oncologist, will have to do with that number, my tumor grade, and the bilateral cancer.
I appreciate that we can share, hopefully make us think, ask questions, and advocate, but not necessarily panic.
Will keep you posted! 🤞🏻

I think you're confusing the OncotypeDX results. The Recurrence Score is a trademarked name for some elements of the results from the algorithm Oncotype uses for the test that suggests the Risk of loco-regional Recurrence within 9 years if the person whose tissue was tested takes tamoxifen or aromatase inhibitors. I had several conversations with Oncotype after getting my result and it's my understanding that one cannot infer much from the Recurrence Score directly except that lower is better. And the Risk score is derived from it.

Oncotype's customer service is excellent and a call to them could help understand what the test can imply and what is outside the scope of the testing parameters.

I have been on Anestrozole since February 2020. Had a problem at first with joints and now doing fine. However, my osteopenia went to osteoporosis. I had my first Prolia shot in January and I am on Osteo-K for bones.

I made it to 4.8 years on anastozole (the doctors being very proud of that) as well as Prolia. I was not without discomfort but I also was doing my best to be a good patient. Everything changed since October with signs leading up to it since July. So I stopped with 3 months to go after discussions with each doctor in January. I do appreciate the info about osteo-K because once I get my BMD, I want to keep any good results without resorting to another medication that will cause everything to hurt. Thanks.
