Sarcomatoid renal (kidney) cancer
This page tells you about sarcomatoid renal cancer. There is information about
Sarcomatoid renal cell cancer is a rare type of kidney (renal) cancer. Different studies give different results but from 1 to 15 out of 100 (1 to 15%) kidney cancers are sarcomatoid renal cancers.
Most kidney cancers start in cells called clear cells, but they can start in other cells too. It seems that any type of renal cell cancer can become sarcomatoid. This means that the cells of the cancer look like the cells of a sarcoma. So they are called sarcomatoid.
Sarcomatoid renal cancers tend to grow more quickly than other types of kidney cancer and are more likely to spread to other parts of the body. This makes them more difficult to treat.
If your cancer is contained within the kidney your main treatment will be surgery. If your doctor feels there is a high risk of the cancer coming back they will recommend further treatment with chemotherapy or biological therapy.
If your cancer has spread or cannot be removed with surgery, you may have a biological therapy, such as sunitinib or chemotherapy.
You can find information about chemotherapy for kidney cancer and biological therapy for kidney cancer in this section. Chemotherapy does not usually work well for sarcomatoid kidney cancer. But it can help to control the cancer and stop it growing or shrink it for a while for some people.
Doctors tend to use similar chemotherapy drugs to those they use to treat other types of sarcoma. This is often a combination of different chemotherapy drugs, including the drug doxorubicin (Adriamycin). Other drugs you might have are ifosfamide, dacarbazine and more recently gemcitabine.
Doctors are still trying to find out more about the best way to use chemotherapy drugs for sarcomatoid renal cell cancer, including giving chemotherapy with types of biological therapy. They are also trying to find out which patients are likely to benefit most from these treatments.
Coping with a rare condition can be difficult, both practically and emotionally. Being well informed about your condition and its treatment can help you to make decisions and cope with what happens.
The coping section has lots of information about coping emotionally, practically and physically.
It can also help to talk to other people who have the same thing. But it can be hard to find people who have had a rare type of cancer. Check out Cancer Chat – Cancer Research UK's discussion forum. It is a place for anyone affected by cancer to share experiences, stories and information with other people who know what you are going through.
