Late-Stage Cancer End Points to Speed Cancer Screening Clinical Trials —Not So Fast

In this issue of JAMA, Feng et al studied whether late-stage cancer (ie, stage III or stage IV cancer), rather than cancer-specific mortality, was an acceptable alternative end point in clinical trials of cancer screening. The authors analyzed 41 clinical trials conducted in Europe, North America, and Asia, combining the data overall and according to cancer type. They evaluated the association between incidence of stage III-IV cancer and cancer-specific mortality in and across the selected studies.
