In oncology, it can be significantly more difficult to find the right patients at the right time for the right clinical trial. Generally, about 30-40% of oncology clinical trials are unsuccessful because they fail to recruit enough patients to complete the trial. This is devastating because 30% of cancer patients are eligible for a clinical trial – and access to a new, promising therapy – but only about 4% of cancer patients end up in a clinical trial. With radiation oncology studies, it can be especially difficult. Those patients who are typically eligible for radiation oncology clinical trials have often already been through months of treatments and procedures before they are visible to radiation oncologists through the typical hospital or healthcare system.
