Biological therapies for stomach cancer
Biological therapies are drugs that help the body to control the growth of cancer cells. Doctors use a biological therapy called trastuzumab (Herceptin) as a first treatment for some people with stomach cancer that has spread to another part of the body.
Herceptin only works for people whose cancer cells have a lot of a particular type of protein called human epidermal growth factor receptor 2 (HER2). Your doctor will test your cells for the HER2 protein.
You have Herceptin into your bloodstream in combination with the chemotherapy drugs cisplatin and capecitabine or fluorouracil.
The most common side effects of Herceptin are tiredness, a mild allergic reaction to the drug, diarrhoea, and changes in the way the heart works.
You can view and print the quick guides for all the pages in the treating stomach cancer section.
Doctors can use a biological therapy known as trastuzumab (Herceptin) as a first treatment for some people with stomach cancer that has spread to other parts of the body. We have information about Herceptin in the cancer drugs section.
Herceptin only works for people whose cancer cells have a lot of a particular type of protein called human epidermal growth factor receptor 2 (HER2). If your doctor thinks that Herceptin could be a helpful treatment for you they will test your cancer cells first to see if the cells have a lot of HER2 protein.
You have Herceptin into your bloodstream, in combination with the chemotherapy drugs cisplatin and capecitabine or fluorouracil. Herceptin cannot cure advanced stomach cancer but trials have shown that it can help some people to live up to a few months longer.
You have Herceptin every 3 weeks as a drip into your bloodstream. You have it for as long as it is controlling the cancer.
The most common side effects of Herceptin are
- Tiredness (fatigue)
- An allergic reaction to the drug
Tell your doctor or nurse if you have any of these effects as you can have medicines to help to control them. You may have other side effects caused by the chemotherapy that you have alongside the Herceptin.
Herceptin can cause some damage to the heart and you will have regular checks to see how well your heart is working.
The cancer drug section has detailed information about the side effects of Herceptin and how they can be managed.
Researchers are looking at some other biological therapies in trials for advanced stomach cancer. But we don’t yet know how well these treatments will work. All new treatments have to go through the clinical trials process and this takes some years. Some research is looking into using biological therapies alongside chemotherapy to see how they work best together.
There is information about research into biological therapies for stomach cancer on the stomach cancer research page.
To search for stomach cancer trials, visit our clinical trials database and select 'stomach' from the dropdown menu of cancer types.
We have detailed information about biological therapies. You can ask your doctor or specialist nurse for written information.
