Colorectal cancer (CRC) is a devastating disease, ranking as the second leading cause of cancer-related deaths worldwide. Immune checkpoint inhibitors (ICIs) have emerged as promising treatments; however, their efficacy is largely restricted to a subgroup of microsatellite instable (MSI) CRCs. In contrast, microsatellite stable (MSS) CRCs, which account for the majority of cases, exhibit variable and generally weaker response to ICIs, with only a subset demonstrating exceptional responsiveness.

Aims: A number of studies have suggested that pancreatic α cells produce intact GLP-1, thereby constituting a gut-independent paracrine incretin system. However, the debate on whether human α cells contain intact GLP-1 and whether this relates to the presence of diabetes is still ongoing. This study aimed to determine the presence of proglucagon-derived peptides, including GLP-1 isoforms, in pancreas biopsies obtained during partial pancreatectomy from metabolically profiled human donors, stratified according to pre-surgery glucose tolerance.

Pancreatic surgery is complex and associated with higher rates of morbidity and mortality compared to other abdominal surgeries. Over the past decade, the introduction of new technologies, such as minimally invasive approaches, improvements in multimodal treatments, advancements in anesthesia and perioperative care, and better management of complications, have collectively improved patient outcomes after pancreatic surgery. In particular, the adoption of Enhanced Recovery After Surgery (ERAS) recommendations has reduced hospital stays and improved recovery times, as well as post-operative outcomes.

Article Synopsis
  • The study investigates how preoperative glucose metabolism impacts the risk of clinically relevant pancreatic fistulas (CR-POPF) after pancreaticoduodenectomy (PD) surgery.
  • Out of 110 patients, those with normal glucose tolerance showed a higher incidence of CR-POPF at 51.7%, compared to those with impaired glucose tolerance or diabetes.
  • Fasting glucose levels and c-peptide values were found to be effective predictors for CR-POPF, indicating that both normoglycemia and normal beta cell function may increase the risk of complications post-surgery.
