Abstract
BACKGROUND: Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare primary malignant tumor. Due to poor understanding of its biologic behaviors, pathological features, image manifestations and clinical effects, clinical study is urgent. Analysis of clinical data of pulmonary LCNEC, in order to improve the clinical diagnosis and treatment.Entities:
