Grace Mishkin, MPH, Public Health Analyst with NCI was interviewed by HemOnc. She reported that “the NCTN, established in 2014, was designed to take more of a network approach to cancer trials. Before NCTN, these trials were conducted as part of the cooperative group system that had been in place for decades.”
National Cancer Trial Network groups:
The combined group has been involved with hundreds of cancer trials. Millions of specimens have been collected. According to Mishkin of the NCI has reported in HemOnc “they (specimens) are quite valuable because they were collected on clinical trials and are associated with considerable treatment and outcomes data that most specimen collections may not have.
