Background: Patients with neuroendocrine neoplasms (NENs) have chronic symptoms from hormone overproduction, tumor growth and metastasis, and side effects from prolonged treatment. We assessed the feasibility of using a digital health platform to recruit patients with NENs to evaluate symptoms and quality of life.Methods: eNET is a prospective, web-based, cohort study for patients with advanced NENs of any primary site, histologic grade, differentiation,...

Background: Patients with neuroendocrine neoplasms (NENs) have a high burden of chronic symptoms. We assessed symptom burden and overall quality of life (QOL) for eNET study participants and analyzed differences by age, sex, and NEN primary site.Methods: eNET is a prospective, cohort study on the Eureka digital health platform enrolling individuals with advanced NENs. Participants completed validated surveys on an internet-supported device at baseline an...

Background: G3NETs demonstrate variable clinical behavior (Ki-67>20-100%). Treatment extrapolated from grade 1/2 (G1/2) NETs and neuroendocrine carcinomas depending on clinicopathologic features. Therapy for treatment-emergent G3NETs remains especially ill-defined.Methods: Retrospective chart review of patients with de novo G3NETs or progressing from low-to-high grade (L-H) (G1/2 at diagnosis and G3 >=3 months later). Treatment patterns compared ...

Background: Serotonin produced by ileum neuroendocrine tumors (i-NETs) promotes development of the mesenteric mass (MM) associated with lymph node metastases. We previously reported that more extensive MM progression along the superior mesenteric vessels predicts a lower rate of complete surgical resection. In this study, we hypothesized that tumoral serotonin production is associated not only with the development of MM but also its progression, and we examined serotonin level...

Background: Serotonin production by ileum neuroendocrine tumors (i-NETs) is considered a critical mediator of the fibrotic reaction in mesenteric mass (MM)/ lymph node metastasis. Antidepressants modify serotonin dynamics: however, their role in MM formation is uncertain. We hypothesized that histories of antidepressant use affect MM formation. This study examined the correlation between antidepressant use and MM formation.Methods: One hundred eighty-two...
