NETest liquid biopsy is Diagnostic of Lung Neuroendocrine Tumors and Identifies Progressive Disease

We examined the utility of a neuroendocrine multigene transcript “liquid biopsy” (NETest) in bronchopulmonary carcinoids (BPC) for diagnosis and monitoring of disease status. Aim: To independently validate the utility of the NETest in diagnosis and management of BPC in a multicenter, multinational blinded study. Material and methods: The study cohorts assess ed were bronchopulmonary carcinoids (BPC) (n=99), healthy controls (n=102), other lung neoplasia (n=101) including adenocarcinomas (ACC) (n=41), squamous cell carcinomas (SCC) (n=37), SCLC (n=16) and LCNEC (n=7) and idiopathic pulmonary fibrosis (IPF) (n=50). BPC were histologically classified as TC (n=62) and AC (n=37). BPC disease status determination was based on imaging and RECIST 1.1. NETest diagnostic metrics and disease status accuracy were evaluated. Upper limit of normal (NETest) was 20. Twenty matched tissue-blood pairs were also evaluated. Data is mean± SD. Results: NETest levels were significantly increased in BPC (45±25) vs controls (9±8, p
