A study based on the California Cancer Registry found that less than one percent of cancer patients enroll in clinical trials. Black patients, those older than 65, those with early stage cancer or with gastrointestinal or lunch cancers were less likely to enroll than average. This is concerning for two reasons: 1. Low enrollment overall raises concersn; 2. The population enrolling in studies is not likely to reflect the average cancer patient.
