TCH (Taxotereinfo-icon or Taxolinfo-icon, carboplatininfo-icon and Herceptininfo-icon) is a chemotherapyinfo-icon regimeninfo-icon used to treat HER2-positive breast cancer. It is a combination of two chemotherapy medicines:

And a targeted therapy:                                                                         

Trastuzumabinfo-icon is a type of targeted therapyinfo-icon called a monoclonal antibodyinfo-icon. It attaches to HER2 (human epidermal growth factor receptor 2info-icon) proteins and can kill HER2-positive cancer cells. 

How TCH Works

Docetaxelinfo-icon and paclitaxelinfo-icon work by damaging the structure or the “skeleton” that supports cancer cells. This stops the cancer cells from growing and dividing. Carboplatininfo-icon stops cancer cells from reproducing by sticking to their DNA.

Trastuzumabinfo-icon (H) attaches to HER2 proteins on the surface of HER2-positive cancer cells, and blocks the signals that cause the cancer cells to multiply.

How TCH is Given

All three medicines are given by veininfo-icon. Trastuzumabinfo-icon can be given first, followed by paclitaxelinfo-icon or docetaxelinfo-icon and carboplatininfo-icon.  It’s also common to receive all three medicines at once.

You will probably have 4 to 6 treatments of paclitaxel or docetaxel, and carboplatin every 3 weeks. You may also get treated on a weekly basis. Trastuzumab is then given weekly or every 3 weeks for a total of a year.
