Background: The lack of predictive biomarkers contributes notably to the poor outcomes of patients with pancreatic ductal adenocarcinoma (PDAC). Cancer-associated fibroblasts (CAFs) are the key components of the prominent PDAC stroma. Data on clinical relevance of CAFs entering the bloodstream, known as circulating CAFs (cCAFs) are scarce.

Objectives: The ability to differentiate epileptic- and non-epileptic events is challenging due to a lack of reliable molecular seizure biomarker that provide a retrospective diagnosis. Here, we use next generation sequencing methods on whole blood samples to identify changes in RNA expression following seizures.

Methods: Blood samples were obtained from 32 patients undergoing video electroencephalogram (vEEG) monitoring.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) of the body/tail is notably different than PDAC in the head of the pancreas. Surgery plus chemotherapy is known to improve outcomes for all PDAC. The sequence of this therapy is well studied in head cancers yet has never been evaluated systematically in relation to distal pancreatectomy (DP).

Article Synopsis
  • The study assesses the risk associated with sub-centimeter Side-Branch Intraductal Papillary Mucinous Neoplasms (SB-IPMN) to inform a surveillance strategy.
  • Sub-centimeter SB-IPMNs show a lower rate of clinically relevant progression compared to larger cysts, although they can still develop high-risk pathologies over time.
  • The findings suggest that size growth alone is not a reliable indicator of malignant potential, emphasizing the need for careful monitoring regardless of cyst size.

Background/objectives: Carcinoembryonic antigen (CEA) is a cell-surface glycoprotein serving as a drug target, diagnostic marker, and serum marker for cancer monitoring. However, prevalence data on CEA expression in cancer tissues vary considerably. This study was designed to determine CEA expression in normal and neoplastic tissues.
