ER-/PR-/Her2+ Rare??

etnasgrl Member Posts: 185

I am not new to the breast cancer world, by any stretch.
My mom passed away from metastatic breast cancer in 2000 and in 2015, I was diagnosed with Stage 1, node negative, IDC ER+/PR+/Her2- in the right breast. Then, in February of this year, I was diagnosed with Stage 1, node negative, IDC ER-/PR-/Her2+ in the left breast.
My oncologist has told me that this type is pretty rare. I have tried researching hormone negative, Her2+ breast cancer, but there is not much info out there. I am just curious to see if there are others on here with this same diagnosis and if so, how are you doing?

    I have hormone negative HER2+...I won’t know how the chemo is working until I’m done with all 6 infusions...but I think I can feel the tumors getting smaller.

    I was just diagnosed with hormone negative, HER2+ IDC in July at age 42. I had my first chemo treatment on Friday. I don't have any statistics or anything about how rare it is, but I have noticed skimming here that hormone positive does seem to be more common. My oncologist believes that if I respond well to treatment I should have less than a 10% chance of recurrence, which is the more important statistic to me than 5 year survival rate (which is estimated to be well into the 96% range.)

    There's a ton of us who are hormone negative and HER2+. I'm not sure why your doc considers this rare. Try searching the HER2 threads on this site. Most of of us are considered lucky because there are so many new treatments out there for HER2. I'm more than 5 years past my last treatments and feeling great. I'm not happy about the lingering neuropathy, but I walk 4 miles a day and do pretty much whatever I want.

    My original diagnosis was for DCIS - hormone negative. They don't check for HER2 with DCIS, but I did have a BMX. Two years later I found a lump by my collar bone. Turned out to be IDC and HER2+ I had neo-adjuvant chemo TCHP, ALND surgery, more chemo - AC this time, radiation and herceptin for the rest of a year.

    Looks like you have a mastectomy coming up. Good luck. Will you have radiation?

    Here's the link to HER2+ topic. There are over 2500 threads.

    I just finished my year of Herceptin. My mammogram and ultrasound was clear except for a very small remaining bit of a seroma from my lumpectomy. I know that there seems to be more HR+ and HR+/HER-2+ people who post here.

    Based on what I have read and observed from reading studies that break participating patients down into categories based on hormonal receptor and Her2 status, Her2+ patients make up about 15-20% of diagnosed breast cancers. I believe ER+/PR+ patients make up about 60% of Her2+ patients, leaving approximately 40% with negative hormone receptors. So, if one to two out of 10 diagnosed are Her2+, and 40% of those are hormone receptor negative - looks like somewhat less than 1 out of 10. Triple negative breast cancer seems to be slightly more prevalent than cases of ER-/PR-/Her2+ at 10-15% of all breast cancer diagnosed.

    Here is a link to a thread specifically for those who are ER-/PR-/Her2+

    Hi, so sorry you have to be back here, but you can see that you have company in the ER-/RE-/HER2+ world. I was diagnosed at the every end of February. Finished 12 weeks of weekly Taxol last week -- not fun, but more manageable than I had feared. 4 weeks of radiation starting at the end of this month; Herceptin every three weeks through May. I take a lot of inspiration from the many encouraging stories on these boards and in the HER2+ thread linked above.

    I second the link that Special K posted. Lots of good feedback & info.

    Also I recommend you join the current chemo thread - like Chemo July or Chemo Club Summer 2020. It really helped to go through chemo with others at the same time, even if our cocktails were different.

    hi UnrealTarHeel- Congrats on making it through the 12 weeks! I hope you are doing ok. I did not really like radiation therapy, I had to hold my breath and was scared that I would mess it up somehow.

    I was diagnosed with hormone negative, her2 positive in December 2019. Finished 6 cycles of TCHP in April. Had mastectomy in May and a pathological complete response to the chemo. Started radiation in July. Will finish radiation in August and finish the Herceptin in December.

    I am doing pretty good. The effects of chemo seem to be gone. My chest is red from the radiation.

    Hi, I have ILC, ER-/PR-, HER2+. I have also been trying to find more info but it seems to be very rare. I was dx on March 16, 2020. I immediately started chemo. I finish this week and then will have a double mastectomy on Sept 18th. Looking to see if anyone else had chemo first, then surgery. If so, did you require chemo again after surgery??

    Joanie - the protocol for HER2+ is pretty much always chemo first. But I can't speak to what the treatment differences might be with ILC.

    My recurrence was IDC - ER/PR negative, HER2+ and one node positive. I did have TCHP chemo first but did not have a pCR (compete response where the tumor disappears). The remains were removed during surgery with good clean margin. However since I'd already had one micromet roaming around, yes I did have A/C chemo after surgery to knock out anything that might have slipped through the net. And then rads with Herceptin for the balance of a year.

    Joan, I've read that only 4 percent of breast cancers are hormone negative/HER2+, and ILC would be a smaller subset of that. With HER2+ cancers, the current standard of care is chemo first. In my case, I achieved a pCR, so no chemo was required after surgery, although the current standard of care if you're HER2+ and there is some residual cancer at the time of surgery, they give you Kadcyla, which I think of as a "smart bomb" chemo--the Herceptin (or Trastuzimab) takes chemo directly to the remaining cancer. This coming Thursday is the two year year anniversary of my diagnosis and at that point, the unknowns were the hardest part. I will finish up active treatment in November (Nerlynx).

    Beesy, thank you for posting that statistic. I've looked for it on the internet but could not find it. 4% would be rare.

    LOL - I guess it is old timers posting time.

    I was diagnosed stage 1 IDC, ER/PR-, HER2+ in November 2006.

    I had bilateral mastectomies (one was a simple to stay even because I was so over endowed it was uncomfortable being lopsided.

    Treat was 4 AC followed by one year herceptin.

    I have been in remission for thirteen years (time from last herceptin treatment).
