Introduction: Neuroendocrine tumors of the lung (BP-NETs) are fairly rare tumors with very heterogeneous behavior and molecular characteristics. They are very heterogeneous concerning their malignancy, ranging from slow proliferating carcinoids (typical (TC) and atypical carcinoids (ATC)) to very aggressive large cell neuroendocrine carcinomas (LCNEC) and small cell lung cancers (SCLC). For the highly proliferative BP-NETs, combined chemotherapy is the standard therapy option,...

Background: Pulmonary neuroendocrine neoplasms are heterogeneous in their clinical behavior and therapeutic options are still not satisfactory. The ‘crosstalk’ of different signaling pathways in NEN cells appears to be more complex as known already. PKI-587 is a highly potent novel dual inhibitor of PI3K and mTORC1/C2.Aim: Therefore, we assessed the effects of PKI-587 in different pulmonary NEN cell lines compared to the established mTORC1 inhi...
