Abstract
BACKGROUND: A debate has been ongoing whether non-small cell lung cancer(NSCLC) with neuroendocrine(NE) differentiation likely indicates malignant behavior, poor prognosis, and sensitivity to chemotherapy. In response to this issue, we retrospectively investigated NE differentiation in NSCLC patients who underwent anatomical pulmonary surgery.Entities:
