Interesting Results from San Antonio Conference/TCH vs ACTH
Hi Ladies
Just spent the morning perusing the results from the conference this last weekend. Lots of good things for us Her2 Gals.
One important note that has been in question in the past and has been brought up as discussion by many on this thread beginning treatment.
The attached link shows confirmed evidence that Anthracycline Therapy is not needed and does not have an advantage in treating Her2 Cancer. TCH or like regimens administered concurrently with Herceptin offer the same efficacy as Anthra. treatments that are up to 4-5x more likely to bring chance of cardiac issues.

now we find out...... sigh. At least this will help in the future. thanks for the info mmm
-
This has been known for some time. The difference in efficacy could be put down to a statistical difference. Anthracycline drugs actually caused leukemia in some patients in one study as well as irreversible heart defects.
-
Thanks for posting this! I knew the statistical difference was very small, but I'm glad to see evidence.

Actually Suepin it was just confirmied at San Antonio, and there are still many Onc's that have been prescribing ACTH for early HER2, and many gals on these threads asking for advice.
-
The slide set that was presented can be found on the BCIRG home page:
http://www.bcirg.org/Internet/default.htm
suemed - while earlier results also indicaated that TCH might be just as effective as AC-TH, they were based on less than 5 years of follow-up (4 years when the 2nd interim results were presented) so there was concern that the gap between the two treatments might widen with more years of follow-up. For example, the FinHER study tested using Herceptin for just 9 weeks vs 1 year and at first the results looked good but at longer follow-up times the recurrences increased in the 9 weeks group.
As the MedPage article indicates, I don't think this release of results will convince all the oncs. The issue that this is one study while AC-TH has results that have been replicated in multiple studies remains. I'm confident about the BCIRG 006 results because it was a large clinical trial and appears to have been well conducted. I'm happy to have had TCH rather than AC-TH but a single study is considered weaker proof than having multiple studies that produce comparable results.
-
My oncologist said he would not give AC-TH to a node negative patient. I'm sorry if some of your doctors over there are behind the times, but I did my research and there was no way I would have let him give me AC-TH. We have to inform ourselves and not totally trust what we're told.
This article dated April 2008 shows this information has been available for some time.

Gals!!!! This is JUST the thread for me today. This whole concept of informing ourselves because WE are the most interested party - you would think that ANYONE with half a brain or a smidge of empathy would understand why we struggle to understand this information - well - today - I had yet another little tussle with my onc - BOY does she HATE it when I raise stuff from my 'readings' - you can just see the contempt behind her eyes when I humbly suggest that I want to try something which may suit me better than the PLAN she has for me...in my case I really really want her to think outside the box in relation to hormonally responsive - but heavily treated ME - instead of steadfastly refusing to look into the research and results on reversing resistance to Femara or indeed reversing resistance to any of the treatments to which one's body adjusts over time and then ignores - I want her to TRY some of these strategies - I am a willing non-nude non-mouse in vivo desperate not to slam the door on my hormone receptors - but oh no....today was just a capper - she managed to introduce more doubt and more fear rather than coming up with a plan to try while I am still not desperately ill...it seems I have become involved in a p*ssing contest with her - who is the cleverest - well clearly SHE is...but who is the more vigilant and engaged - well.... I know the only real answer is to try another onc - but they are thin on the ground where I live and since I still work it is hard carving out the time from my busy life of servitude to address survival - but I fear the time is upon me....What makes me really grateful is that there are others out there who are trying so hard to beat this using their minds and everything else and who are not afraid to try and inform themselves rather than blindly just taking whatever we are told to take...it makes me sad and very scared that this desire to participate in our own survival so often works against us - yes....I have been referred to a shrink now to help with my 'anxiety'....if only shrinks could cure cancers and egos - I would gladly go
Sorry for the rant...very bad day - despite the hopeful glimmers from San Antonio which I was kinda hoping she had also read!!!!

Fidela,
Get a second opinion - she sounds like a total bitch.
I'm lucky in that my onc is also my husband's onc (all clear) and we have known him for 7 years. He is well used to us coming in armed with clinical trial results and articles. He once mentioned a drug given for bowel cancer that had really nasty side effects and DH said no way I'm having that and he was fine with it. DH actaully did get a second opinion once and the onc was fine with that too.
There's a lot of garbage out there on the net but if you only take notice of medical articles and trial results then you should be OK. I sound like a walking medical encyclopaedia.
When we were talking about my treatment, he started to mention anthracyclines and I sat up alert having prearmed myself with the facts. Then he said they only give AC-TH to node positive patients. I said "Good I'll have TCH". He laughed and wrote it down and ticked it. Then he asked me the side effects.
He respects that we are intelligent which is a big change from my breast surgeon (not going near him again). The surgeon resented us asking intelligent questions. He had a spiel he wanted to get out and didn't want to be interrupted. He got the shits because I had already made an appt with the onc when I saw him post op reckoned he should do that. If I know who I want, I'll make my own appointment. Should have ditched him the first time we met him but when you want surgery in a hurry you take it. Technically he was good.
Pity you couldn't have my guy but you would have to move to Oz for him. He's in San Antonio this week - goes every year - don't kidnap him.
SO, stand up for yourself. I hope you can get someone else.

I know what you mean about bucking the onc's opinion. My old Onc gave me Herceptin with my first A/C chemo and I later read on Genentch's drug fact sheet that they are never to be given together. I also found the same info from Sloan Kettering.
I called his office told the nurse what I found out and she said "where did you hear that? We do this all the time!". I said "Sloan Kettering" and she got quiet and said she'd talk to to the Onc.
Later they called me back and said they'd wait until after I finished the chemo, to give me the Herceptin. I told them that's all I wanted. Onc was a little snippy with me next time I saw him, but I let it go and things were ok after that.
They did decide to also wait until I'd finished my rads to start my Herceptin too, because I was having targeted rads right over my aorta.
I never had Taxotere though, and my new onc (my other one retired) questioned why I didn't have it. I said I wondered the same thing, although at the time I didn't think about it because I was so sick. She said, too late now, as I've been out of treatment for over a year and a half.
So, I guess I will find out whether the lack of a Taxane makes any difference in disease free survival.

Just to give you my experience on this one, I was newly dxed last year and I came in to the number 1 rated Onc in the PHX area. He prescribed 4x TCH for my node neg Her2 tumor. For some reason he also sent it out for oncotype and afterwards found that most don't send out her 2 tumors as they will most likely get chemo. Well never heard back and went in for my first chemo, and I was sitting in the chair literally getting hooked up and My onc called me on my cell and said the Oncotype was back and we needed to talk about chemo. I said I was in the chair and he came running over (literally) and said my oncotype was very high (like duh it was her2) and he wanted to change my chemo to 6x ACTH, and had ordered the new regimen to be mixed. I stood right up and said wait won't that cause heart issues and he said there is a chance but we need the big guns. I said no!!
3 opinions later and all 3 stated I may have even been overtreating with TCH as now Taxol and Herceptin are being favored for node neg. WOW, and now 2 of my friends with ACTH are on drugs for Congestive heart failure.
-
mmm5: Boy are you lucky you stood up to him. We don't have the oncotype dx test in Australia and it would cost about $6000 to send a sample over. Don't worry I asked him about it.
brenda_r: My oncologist didn't give me herceptin with the first TC treatment so he could see which drug, if any, caused a reaction. I thought that was really good. One of the girls on these boards had a nasty pussy rash after her first TCH and they didn't know what caused it.
-
I should have clearer, it's the Adriamycin that isn't supposed be given with Herceptin, as both can cause heart problems.
About that reaction, I had about every other SE from the A/C but I didn't have that one, thank goodness.
-
Brenda_r: I knew that about andriamycin - you had a lucky escape. I can't beleive that your guy would even think of giving both at once. I was just pointing out how careful my oncologist is when giving treatments.
