Neoadjuvant TCHP, pCR and HER2/neu

I am a 24 yr old diagnosed with stage 1b, grade 3, triple positive IDC 9/12/2016, and I started my neoadjuvant TCHP on last Friday 10/21/16, so far no bad SEs. I have consulted several MOs and they all told me that my chance of getting pCR is very high due to my highly overexpression of HER2/neu (13.9), and high grade tumor.

But I also read that the ER+PR+ tumor has lower chance for pCR compared to the hormone negative ones.

So just wanna to know for those of you who have achieved pCR from TCHP,

what is your:

HER2/neu,

ER/PR status,

and tumor grade?


Thanks!!

    Hi Qianqian, This is not the first, or the last time you'll hear this, but we are sorry that you were diagnosed at such a young age! For those who may not understand, pCR means "pathologic complete response", if no active cancer cells are present. One way doctors judge the effectiveness of neoadjuvant chemotherapy is to look at the tissue removed during surgery to see if any actively growing cancer cells are present. We suggest also that you type pCR into the Search box in the Community on your left-hand navigation. There are a number of posts of members discussing.

    We're ll here for you!!

    I was 39 when diagnosed in early March 2016. Not sure of my Her2 status, other than I'm positive, but my ER is 95%, my PR is 12%, and my 2.2 cm tumor was grade 3, stage IIa. Ki67 score was around 32% (or close to that). I felt a noticeable reduction after the first round of TCHP and the follow-up MRI after three rounds showed a 70% reduction. My lumpectomy after 6 rounds showed a PCR. I'm still doing radiation and Tamoxifen, however.

    Hi Qianquin,

    I was wondering what the name is of the test that told you that you were highly HER2 over expressive. I haven't had a test that tells me what level of HER2 expression is; I only had an IHC test (which showed that I was a 3). I was a 9/9 on the Nottingham scale. The only test I am sad about getting a perfect score on... But I wonder if that means I highly overexpress HER2?

    Thanks very much.

    The initial diagnosis of the tumor found in my right breast was Stage 2, ER+PR-Her2+. The tumor was 4.5 cm. I started with Herceptin and Perjeta only but the treatment didn't shrink the tumor the way my oncologist wanted it to be. So Carboplatin and Taxotere were added to my treatment. I completed neoadjuvant on September 8 and had my bilateral mastectomy without reconstruction on October 20. I received my pathology report today and I had a pCR! Lymph nodes and margins were negative. The chemo obliterated invasive cancer cells and left 1 mm DCIS which they removed. I was thinking that I will be undergoing radiation due to the size of the tumor at the onset of the treatment but the radiologist said that I don't need it. I hope that I will not regret this later on. I will be continuing Herceptin for a year. Right now, I am just so happy with the result.

    That is wonderful news. I too had almost a complete response to TCHP. I had a 2.1cm tumor shrink to 4mm of scar tissue and DCIS only . Radiologist said he considered it a complete response. I DID have 36 days of radiation. 28 of whole breast and 8 of targeted boost to scar area. Are you pre or post menopausal? My understanding is that if you are PRE, that radiation is very important. Of course everyone is different and there are more than one way to treat. If you are PRE, I might get a second opinion at another radiologists office.

    Hello ChinookMom,

    I was skeptical at first with the effectiveness of the neoadjuvant TCHP regimen because the imaging results taken after my chemo showed that the tumor didn't shrink at all. In fact, I was very disappointed. I wasn't really looking forward to my surgery. Thus, you can just imagine the happiness (which is an understatement) I felt when my health provider informed me that I had a pCR. Up to now, the result has not sunk in yet and I still feel apprehensive due to recurrence or even metastasis. But I told myself to just enjoy the peace that the moment gives and move forward with my second life and deal with recurrence or metastasis when it comes. The rationale of my radiologist for not giving me radiation is because the invasive cancer cells are gone, the two lymph nodes they took out tested negative, margins from the tissue were clear, and they took out the remaining noninvasive cancer cells which measured 1 mm. I didn't know that one's status as pre or postmenopausal is a factor in radiation until you told me. I had preventive TAB hysterectomy two years ago which made me undergo surgical menopause. How did you feel after you finished treatment and how fast did your hair grow back? My hair is starting to grow back and my hair shaft measures about 4 mm.

    ER 98%
    PR 97%
    HER2 positive but not sure of a # on that? My report shows a ratio 10.2:1
    Grade 3
    28 years at diagnosis. MRI & Ultrasound showed my tumor was 1.6 cm. I had a pCR after only 2 TCHP infusions. They wouldn't give me any more because my WBC would not recover. After surgery they did let me have the rest of my Perjeta which I finished and I am now on Herceptin only along with zoladex and arimidex. For me Taxotere and Carboplatin had horrible side effects, but Perjeta and Herceptin have been a breeze.
