SANTA CLARA, Calif. – Just as it does with treatments, the National Comprehensive Cancer Network (NCCN) offers detailed guidelines on genomic testing by cancer type. These are key in determining what physicians can prescribe routinely and what insurers will cover. But those guidelines aren’t followed regularly outside a major research hospital setting, thereby obviating access to tumor genetic information that could help to better guide treatment. Even if current guidelines are followed, physicians and patients can get information back from the tests that neither party is prepared to process.
