- The human immune system is a powerful defense against
- assaults by bacteria and viruses from outside the body, but now
- scientists may have found a way to turn it against a homegrown
- assailant: cancer. A research group at Stanford University has
- developed a vaccine that stimulates the body to fight B-cell
- lymphoma, a cancer of the lymphatic system that strikes 20,000
- Americans every year and is especially hard to treat. They did
- it by removing cancerous cells from nine patients and treating
- the cells to make them more irritating to the immune system.
- Then they were reinjected under the patients' skin. In two
- cases, as reported in the New England Journal of Medicine,
- tumors actually shrank, while five other patients showed
- markedly increased immune-system activity. The vaccine isn't a
- preventive and can only be used on a single patient and against
- this type of cancer. But the technique may someday be used on
- other cancers and also on such diseases as multiple sclerosis,
- diabetes and rheumatoid arthritis.
