The condition and the treatments
When prostate cancer has spread to another part of the body, it is called metastatic prostate cancer. In most men with prostate cancer, the hormone testosterone makes the cancer grow faster. So prostate cancer can be treated with drugs that make the body produce less testosterone, or react to it in a different way. This is called androgen deprivation treatment.
After a time, the cancer stops responding to such treatments – this is known as 'hormone‑relapsed' cancer.
The eastern cooperative oncology group (ECOG) performance status is a measure of how well you are. An ECOG status of 0 means that you are fully active, more or less as you were before your illness. A status of 1 means that you can't carry out heavy physical work, but can do anything else.
Cabazitaxel and docetaxel are anticancer drugs, used to kill cancer cells. Cabazitaxel is given by infusion into a vein. It is given with another drug called prednisone or prednisolone, which is taken as a tablet.
