Don't Want to Take Tamoxifen

Options

Hello,

I am trying to justify not taking Tamoxifen despite my medical oncologists 150% recommendation that I take it. I would prefer a more holistic approach and I am simply concerned about the toxicity of the drug. Secondarily I am concerned about the side effects (fatigue, depression) give that I already suffer with those. My genetic testing was negative, my initial Oncotype score on my DCIS was 15, and my Oncotype score on my IDC was 9. I am getting ready to go through radiation.

I had a 2nd opinion with Dr. Lagios who stated that my distant recurrence rate after 15 years would be 3% to 4%. Tamoxifen could reduce that to 1.5% to 2%. He recommended that I receive a Mammaprint test to see how aggressive the tumor is to justify the decision to not take Tamoxifen. Not sure if I am eligible or if insurance would pay.

In reviewing my medical oncologist's notes (before the Oncotype score was received) it appears that the recurrence statistics are between 3% to 5% (not sure if this is with / without Tamoxifen).

It seems like such a small reduction in an already low risk percentage to warrant Tamoxfien.

Do these percentages sound correct? What are other people's opinions?

Thanks in advance!

    I'm in a similar position.Did T for 2 yrs, femara for 7 mo and I'm now back on T. My oncotype was 3 for a 4% recurrence with T max 8% without. I'm still slogging it out. I have 2 years 3 mo to go. Ugh.

    I didn't have an oncotype or mammaprint because of HER2+ and nodal involvement. But I just asked my MO how much risk reduction am I actually getting from the Tamoxifen and in my case he said 10%. I was hoping he'd say 1-2% so I could justify not taking it but 10% is a pretty significant number. I've been on the Tamixifen for 7 weeks but I'm seriously considering stopping it. I don't like the aches and pains, personality change, or excessive hot flashes. MO told me to tough it out for 3 months and then decide. He said he thinks I should stay on it but understands that quality of life is important too. I'll give it 3 months and then reasses

    Because we know so little about our own particular bodies' physiology and how we will react to a drug, it's hard to advise you here. In my case, because I am high risk, I wanted to give myself every opp to get rid of BC once and for all. That's why, even though my protocol didn't completely require it, I went ahead and did everything humanly possible to eradicate BC from my body.

    I understand your concern about toxicity; there are ways to reduce toxicity when we are on drugs other than simply not taking them. Again, deciding to risk a recurrence or not will be your individual choice--we are all on our own path. It's possible that the percentages you mention won't help you. But why not try the drug for 3 months and see how you react to it? Millions of women are on these types of therapy to prevent recurrence and have no side effects whatsoever. My experience with tamox was okay, but when I menopaused completely I was moved to Arimidex, which caused massive side effects. My MO then switched me to Aromasin, and so far it's been so much better.

    How will you know how you react until you try? Then you'll know and perhaps can live with not taking it if you do have a reaction. My 2 cents, adjusted to 10 for inflation :)

    I agree with Claire. Give it a try, and if you have trouble with it, then stop. I have no SEs from Tamoxifen at all except for hot flashes which I had anyway due to chemopause. My MO says that only a handful of women in her practice experience severe SEs. FYI survival rates calculated by Oncotype assume that you will take Tamoxifen. It is at least worth giving it a try. I fretted and delayed taking Tamoxifen, now that I've been on it spice April, I laugh at myself for over worrying

    I also agree with Claire. If you are using bco as a gauge for possible reactions to tamoxifen, you are getting a heavily slanted perspective. People, generally, don't post to say things are going well and se's are minimal or non-existent . Millions of women take it with few to no se's. Try it and it becomes unbearable, you can stop

    Farmerlucy,

    Thanks for your response! Are you saying your Oncotype score was 3? Did that translate to 8% risk w/o Tamoxifen, and 4% with? I thought the Oncotype score assumed the patient took Tamoxifen.

    The lowest recurrence rate on the chart is around 4% (when I rec'd my results in 2012) even with a 0 score the recurrence rate is around 3 - 4%. So doubling the 4 to an 8 is my calculation for my risk without T. 50% improvement from 8 is 4. So my max improvement with T is about 4 %. However - my onc said "that's a lot of faith to put in that one number". I didn't take it for a year, then the monkey on my back from knowing I wasn't doing everything I could to prevent recurrence was worse than just taking the stupid pill. I agree with everyone else. It can't hurt to try. For me it was a freedom of sorts. When I started taking it I knew I was doing all I could. The rest was not up to me. My main SE is HFs and I take Effexor to help with that. Do I like taking it? No way. Will I keep taking it? Probably.

    I find the percentage risk your doctor told you to be odd. Where did he come up with that percentage and what does your Oncotype result actually say? I, too, had an Oncotype result of 9. The results list my 10 year distant recurrence risk as 6% with 5 years of Tamoxifen. Tamoxifen has been extensively tested and has shown to reduce the risk of recurrence by around 40% (30-50%), so my risk without Tamoxifen is about 10% (+- a few percentage points).

    I attempted to take Tamoxifen twice and experienced severe side effects so I am now accepting my 10% risk of recurrence. I definitely recommend giving Tamoxifen a try, though, as most women have minor side effects or even none at all. Also, the side effects I experienced went away within a few weeks of stopping the drug.

    SummerAngel,

    Thanks for your response! Yes, based on an Oncotype score of 9, my recurrence risk is calculated at 6%. So it appears we have the same score / risk. I am unsure where Dr. Lagios got his percentage risk from. I believe he dials down the risk based on his opinion that Tamoxifen is not very effective against DCIS.

    I am thinking a trial of Tamoxifen is a good idea.

    Hello Sisters & Comrades, this is my first post... yes, the club none of us wanted to belong in.

    I'm new to forums so maybe this is not where to post but it seems the closest subject- feel free to guide me. It has been a roller coaster ride since being diagnosed in October. I'm 56-1/2 years old and still premenopausal (believe it or not). You would think that two lumpectomies and then a mastectomy (margins weren't clear until my mastectomy) would be the hardest part but I too am faced with this difficult hormone therapy dilemma that sometimes seems almost as overwhelming. Neither radiation nor chemo were in my treatment plan due to my 8% onco score.

    I'm really not not liking the sound of the hormone therapy SEs for the next 5-10 yrs. It would most likely include tamoxifen until I'm menopausal, then switching to an AI, which can be even worse I hear. I'm worried most about the heart issues in my family history (aunt, Mom, granddad all had strokes, Dad had cardiomyopathy) coupled with my age, with regard to tamoxifen SEs. I brought up the idea of the injections to stop ovarian production of estrogen and my MO said we could do that instead or in addition to tamoxifen. (I believe the SOFT study might say I'm not the best candidate for both however due to my age?) I guess my main questions are, what about the shots vs tami with regard to both SEs and recurrence rates? Would either choice still mean that my recurrence rate (as determined by Oncotype score) is still 8%, or is the stat based on my taking just tamoxifen?

    My MO appt was last week, and I was not prepared to make a decision then and there, despite my previous research and the fact that he answered all of my 15 questions, ha. I'm getting a second consultation with another MO on Monday, and I'll hit him with a new round of questions. I'm questioning my first MO's knowledge now as I read here about various tests for hormone levels, enzymes levels, etc which he failed to acknowledge were valid or necessary when I asked. So now I'm even doubting if he is the best for me. It is important to me to know that the drug would be helping me (!), and that they can monitor me - but it all seems so arbitrary! Also it doesn't help that this former city girl now lives in the boonies, and my doctor choices are limited unless I want to drive 3 hours for each doc appt.

    Sorry so long- Thanks to all who contribute here, it really feels like an incredible sisterhood of support and wisdom, and for that I'm grateful.

    Hi PhoebeLee - Welcome to BCO. You're right is it an exclusive club. Girl - I didn't want to take Tamoxifen either. It took me a long time to get to the point where I would give it a fair try. When I did my main SEs were hot flashes, oh and probably weight gain, but that may be because well, I like to eat!

    It not clear to me if your oncotype score is 8 or your recurrence % is 8. If the recurrence % is 8 with Tamoxifen, your recurrence would roughly be 8 x 2 (roughly) without Tamoxifen. The oncotypedx test assumes its use. Since AIs are a bit more effective, I like to think I'd get an extra point or two if I used them instead of Tamoxifen.

    Here is one thing that helped me. Early on I met with a psychologist to help me deal with the terror I was feeling from dx (can you say - full blown breakdown?). Anyway, as it turns out she was a 26 year BC survivor. She said she had been on HRT before dx. It was tough for her to drop that cold turkey. Since tamoxifen can acually increase your estrogen but T's job is to block any of those rogue buggers from feeding off it, she told helfself it was her BC HRT. That's what I'm going with too. I was premeno at 54, but I had an ooph last spring. Even at that age I still felt the effect of having my ovaries out.

    Take care. Let us know how everything is going!

    farmerlucy, thanks for the quick reply! My oncotype score was/is 8%. I know that this assumes taking HRT, as without it this would mean 16%- is 16% the "recurrence rate" then? So confusing for us beginners :/

    I'm wondering however if this 8% score is after taking tamoxifen, or whether it could also be after having the monthly ovarian suppression injections (zoladex)?

    Boy, do I hear you on the "breakdown" part. I've always been anxious, but this dx has ramped everything way up. My particular manifestation is meltdowns or crying jags when on the phone with receptionists. The biggest was when the radiation oncologist's office had not gotten the memo that i had had a mastectomy, and were bent on scheduling me an appt. The radiation oncologist was on weeklong vacation (of course) and no one on the phone could tell me why. I assumed the worst. I have come to realize both parties play a role- me for my anxiety that makes me feel like a child without a mother, to them, for what seems to be the fragmentation of care/lack of communication between specialists. I have a local counselor that I've been seeing since my dx, but I'm also not satisfied with her. I wish there was an anxiety specialist nearby. There is such a lack of quality care where I live, all the more reason this site is helping me.

    Hi there! For what it's worth, I have been on Tamoxifen for two years and have had very few side effects. I was scared too, but I am in better health than ever and regret waiting 3 months to start it in the beginning.

    A follow up: I've been taking tamoxifen for only five days- so far so good! ;) I'm questioning whether to take it morning or night as I'm not sleeping through the night that well, but this was really the case before the tamoxifen however. What made the difference to my being good with the decision was my second opinion with a new oncologist. His answers were much more lucid, and I felt that he took my concerns more seriously. I asked him if he had any openings for new patients and when he said yes, I switched oncologists! Early on I just did not feel there was time to shop around.

    Concerning tamoxifen, the most interesting thing is that I was already having hot flashes before taking it, and they seem to have lessened a bit :/ since taking it. I still have light ones a few times a day, just not the huge waves that used to come over me. Wondering how long until this drug is absorbed in my system. Seems funny to "look forward" to hot flashes, as an indicator the tami is working, doesn't it? Or maybe I'm wrong about this premise in the first place...

    Hi there. I can't understand why people are so anti this drug. I just don't get why someone wouldn't try something first. Sure if you don't like it after trying it stop it, but why not try it? I have been on it for about 10 months now I guess and it is 100% better than Letrozole/Femara that is for sure. If you do get side effects they seem to wear off. I have never felt as good as I do now - hot flushes and all. Anyway good luck :)

    I don't want to take tamoxifen because of the side effects. Weight gain is #1. I've struggled to keep weight off since I entered menopause. I did lose 6 pounds wihile getting radiation therapy, but I barely ate during those 3 weeks. Cataracts. I go for eye exams every 6 months and I already have small cataracts. I'm afraid the tamoxifen will make them worse. Joint pain. I have pain in my hips, especially the left one. I have had PT on both of my shoulders. Again, I'm afraid the tamoxifen will make this worse. I have an appointment scheduled to see my internal medicine doctor in a few weeks. I will have blood work done and also a bone density test. He knows my medical history much better than my MO and RO so I will be guided by his advice.

    I've only been on it for about a month, but the side effects haven't been bad. I had a nagging headache in the first week or two and that went away. Hot flashes come and go but it's nothing I haven't experienced before! I haven't had any more joint pain that I had before tamoxifen. With hormone positive cancer, tamoxifen or aromatase inhibitors are the most important part in preventing recurrence.

    Phoebe, I was told to take tamoxifen at night. It might be due to how it metabolizes in the body, since it can interact with quite a few things. I think having hot flashes means it's doing something, it better be!

    Take care!

    ctgal - I think it is a whole different decision process when one's dx is pure DCIS. But what do I know. BUT if you don't take it you'll miss out on all those cool Tamoxifen dreams! Wow! Talk about living color!

    I'm on Femara and have no love for it either. I did find the side effects improved after 6 months. If you're premenopausal, you can ask your Dr. how to shut down your hormones so you can take an AI. It's one option.

    Hormone treatment is one of our most effective tools against reoccurance. If older, that's one thing, but you have a lifetime ahead. Back surgery in my early 30s has robbed me of far more life than Femara ever will
