A novel molecular classification for small cell lung cancer (SCLC) has been established utilizing the transcription factors achaete-scute homologue 1 (ASCL1), neurogenic differentiation factor 1 (NeuroD1), POU class 2 homeobox 3 (POU2F3), and yes-associated protein 1 (YAP1). This classification was predicated on the transcription factors. Conversely, there is a paucity of information regarding the distribution of these markers in other subtypes of pulmonary neuroendocrine tumors (PNET).

Introduction: Lung cancer is a major cause of cancer-related deaths, with 2 million new cases annually. Bronchopulmonary neuroendocrine tumors (BP-NETs) comprise about 20 % of lung cancers, including typical carcinoid tumors (TC). While tobacco is a primary risk factor, non-tobacco factors also play a role.
