A trial of gefitinib (Iressa) for advanced synovial sarcoma (EORTC 62022)
Synovial sarcoma is a type of soft tissue sarcoma. Doctors usually treat it with surgery, sometimes followed by radiotherapy. But sometimes this treatment doesn’t work very well and the sarcoma starts to grow again, or spreads to another part of the body (metastasises). When this happens it is called advanced sarcoma and is more difficult to treat. Doctors may offer chemotherapy to help control the cancer. But in time, it will start to grow again.
Gefitinib is a type of drug called a tyrosine kinase inhibitor (TKI). Cells have ‘epidermal growth factor receptors’ (EGFR) on them. When these receptors are triggered, it sets off a chain of events that tells the cell to grow and divide. Gefitinib blocks tyrosine kinase, which is part of this process.
If gefitinib can stop tyrosine kinase from working, it could stop the cancer from growing. But as this is a relatively new treatment, doctors were not sure how well it would work for synovial sarcoma.
The aims of this trial were to
- See how well gefitinib works for advanced synovial sarcoma
- Find out more about the side effects
Summary of results
The research team found that gefitinib did not help patients with advanced synovial sarcoma.
46 patients with advanced synovial sarcoma were recruited on to the trial. They all had cancer that was no longer responding to chemotherapy. They were all treated with gefitinib
- The cancer did not disappear (
complete response) or get smaller ( partial response) in any of the patients
- 6 weeks after treatment started, the cancer had continued to grow in 32 patients (70%)
- In 10 patients (22%) there was no change in the size of the cancer (
- 3 months after treatment started, only 5 patients had stable disease
They concluded that gefitinib should not be used on its own to treat synovial sarcoma. But they suggested that it may still have a role in combination with other treatments in the future.
We have based this summary on information from the team who ran the trial. The information they sent us has been reviewed by independent specialists (
