Background: There is currently no effective blood biomarker for lung neuroendocrine neoplasia diagnosis and management. We describe the clinical utility of a 51 neuroendocrine-specific gene expression set in blood to diagnose bronchopulmonary neuroendocrine tumors (BPNETs) and define their clinical status.Methods: The discovery set included BPNETs (n=154) and controls (n=90), randomly assigned (1:1) to a test and validation set. Specifi...

Introduction: Surgery is the only cure for neuroendocrine tumor (NET) disease. R0 resection is critical for successful tumor resection. Early detection of residual disease is key for optimal management. Both imaging and current biomarkers have intrinsic limitations and are largely ineffective up to 3 months post-surgery. NETest, a multigene blood biomarker test, identifies NETs with >90% accuracy. We hypothesized that surgery would decrease NETest levels and that elevated scor...
