Background: Lu177 has shown efficacy in advanced NET with significant hematologic toxicity, including therapy-related myeloid neoplasm (t-MN). CH is defined by acquisition of somatic mutations in hematopoietic stem cells with potential for expansion over time. In this study, we aimed to assess the prevalence of CH in NET patients (pts) prior to Lu177 along with the incidence of cytopenia in NET pts treated with lu177 based on the CH status at baselineMet...

Background: Neuroendocrine neoplasms (NEN) are known to be associated with specific familial syndromes. However, the incidence of pathogenic germline variants (PGVs) in unselected NEN patients is unknown. In this study, we aim to determine the prevalence and clinical utility of PGVs in unselected NEN patients using universal a genetic testing approach.Methods: We undertook a prospective study of germline genetic testing using a > 80 gene next-generat...
