NCI Definition: A usually aggressive carcinoma composed of large malignant cells which display neuroendocrine characteristics. It is characterized by the presence of high mitotic activity and necrotic changes. The vast majority of cases are positive for neuron-specific enolase. Representative examples include lung, breast, cervical, and thymic neuroendocrine carcinomas. [1]

Large cell neuroendocrine carcinomas most frequently harbor alterations in TP53, STK11, KEAP1, KRAS, and RB1 [2].

Most Commonly Altered Genes in Large Cell Neuroendocrine Carcinoma

TP53 Mutation, TP53 Missense, TP53 c.217-c.1178 Missense, KEAP1 Mutation, and STK11 Mutation are the most common alterations in large cell neuroendocrine carcinoma [2].
