Re: DCIS & her2+?
I had both. HER2 was treated with chemo TCH and DCIS radiation due to mine being at the skin level down to my chest wall.

Re: DCIS & her2+?
Thanks Snolan, the lady I know is early stage and Onc suggesting no herceptin so was concerned this was right?

Re: DCIS & her2+?
I was stage 1 and still did herceptin. Early on when herceptin was just strating it wasn't used for early stages but is now. You may want to recommend a second opinion. It is the main treatment specific to HER2, mire of an immunotherapy.

Re: DCIS & her2+?
DCIS is usually NOT treated with chemo or herceptin. It is usually treated with surgery followed by radiation. Mine was ER-, PR- and HER2 + at 3+. I begged for herceptin to try to reduce the chances of recurrence but was denied. Unless the DCIS is found to be in the chest wall or skin (which by definition DCIS is only in the ducts and lobules) it is treated by surgery to remove the lesions followed by radiation.

Re: DCIS & her2+?
Thanks for the info VDC, I'm surprised at that and had thought all her2+ would have herceptin regardless.

Re: DCIS & her2+?
The thing is, DCIS is NOT considered invasive. That means it lacks the ability to spread beyond the ducts or lobules. However, 25% of DCIS (and particularly high grade including HER2+) is found to be invasive at the time of surgery. IF the DCIS is found to have invasion or micro invasion then herceptin is used as treatment and chemo as well. But as long as the DCIS is found to ONLY be DCIS, then neither chemo or hercpetin is allowed.
The interesting thing is that sentinel lymph nodes are NOT usually removed with DCIS for the same reason. If it isn't invasive then there should be no way for the cancer to spread....in theory at least. There was a research study that DID take a sentinel lymph node with DCIS and it found that 2% of DCIS cases DID have micromets in the sentinel lymph node. ALL of the 2% with micromets had biopsies prior to the dissection. It was unknown if the biopsies had allowed the pure DCIS to spread beyond the ducts or what other reason there might be for the few cancer cells in the lymph nodes.

Re: DCIS & her2+?
I was already on Herception for Stage IV when I got DCIS. I had a lumpectomy and then a double mastectomy, which my surgeon did not want to perform and tried to talk me out of.
Almost 10 years later, and I'm still here.

Re: DCIS & her2+?
too risky not to get Herceptin. DCIS can become invasive and metastatic, don't risk it.

Re: DCIS & her2+?
Herceptin isn't an option for DCIS. I tried, I begged, I sought a second opinion. Because DCIS is not considered invasive it is NOT given for DCIS.....even when desired by the patient. Believe me, I tried!
So, even if WE think it is required for DCIS, the medical community does not think Herceptin is allowed for DCIS...unfortunately.

Re: DCIS & her2+?
I thought now it was given to all HER2 patients. Should be.
