Clinicopathological features and prognostic implications of ASCL1 expression in surgically resected small cell lung cancer.

In limited staged pure SCLC, ASCL1 expression was positively correlated with NE signature, pTNM stage, nerve invasion and OS. ASCL1 may therefore serve as a potential biomarker to predict prognosis as well as in the selection of patients for therapies targeting ASCL1-regulated downstream molecules.
