Background: Guidelines for some pancreatic neuroendocrine tumors (NETs) have shifted towards active surveillance given the indolent nature of this malignancy. We sought to assess the safety of delayed surgery on colorectal NETs as a surrogate for surveillance.
Methods: Resected, stage I, well-differentiated colorectal primary NETs included in the Surveillance, Epidemiology, and End Results Program from 2010 to 2020 were included.

Background: Colorectal cancer (CRC) ranks as the fourth most common cause of brain metastasis (BM), with its incidence on the rise. However, the molecular mechanisms driving the formation of these lesions from CRC remain unclear.
Methods: We analyzed the FoundationOne genomic database, which includes over 35,000 CRC samples from both local and metastatic sites.

Gastroenteropancreatic neuroendocrine neoplasms(GEP NEN) exhibit substantial biological heterogeneity, impacting clinical management and outcomes. In 2019, the WHO introduced the neuroendocrine tumour(NET) grade 3 (G3) subgroup, characterized by Ki-67>20% and a well-differentiated morphology and poorly differentiated neuroendocrine carcinomas(NEC) (Ki-67>20%). Since this update, questions about the prognostic implications and best treatment strategies for NET G3 and NEC remain.

Aim: Accumulated data suggest that routine use of defunctioning stoma in low anterior resection for rectal cancer may cause kidney injury, bowel dysfunction and a higher risk of permanent stomas. We aim to study whether avoidance of a diverting stoma in selected patients is safe and reduces adverse consequences.
Methods: SELSA is a multicentre international prospective observational study nesting an open-label randomized clinical trial.

Early-onset colorectal cancer (EOCRC) is an alarming entity worldwide. Yet, stage-specific characteristics and prognosis in localized and synchronous metastatic EOCRC are not well-defined. Two cohorts of CRC patients (localized and synchronous metastatic) were evaluated, defining EOCRC as the diagnosis <50 years old.
