Article Synopsis
- Intraductal oncocytic papillary neoplasms (IOPNs) are now identified as distinct from intraductal papillary mucinous neoplasms (IPMNs), with limited information on their recurrence and survival outcomes.
- A study analyzed outcomes of 415 patients with invasive IOPNs and adenocarcinoma from IPMN over a median of 6 years, finding similar recurrence rates between invasive IOPNs and ductal A-IPMN, but poorer survival compared to colloid A-IPMN.
- The research concluded that invasive IOPNs behave like aggressive cancers, with adjuvant chemotherapy showing no significant impact on recurrence rates in any of the studied cancer types.
Pancreaticoduodenectomy (Whipple's procedure) is a technically demanding operation performed for malignant and premalignant conditions of the pancreatic head, duodenum and bile duct. Awareness of the vascular anatomy, variations, and pathology of this area is essential to achieve safe surgery and good outcomes. The operation involves division of the gastroduodenal artery (GDA) which provides communication between the foregut and midgut blood supply.

- The study examines the outcomes of different precursor epithelial subtypes of adenocarcinoma from intraductal papillary mucinous neoplasms (A-IPMN), focusing on clinical features and recurrence patterns among patients who underwent pancreatic surgery.
- A total of 297 patients were analyzed, revealing that gastric, pancreatobiliary, and mixed subtypes have similar outcomes that are worse than the intestinal subtype in terms of recurrence and overall survival.
- The research found that adjuvant chemotherapy specifically improved survival rates in the pancreatobiliary subtype, but not in gastric, intestinal, or mixed subtypes, indicating a potential area for further exploration in treatment strategies.
Article Synopsis
- - The study investigates factors affecting long-term survival and recurrence in patients with adenocarcinoma from intraductal papillary mucinous neoplasms, focusing on those who had pancreatic resection between 2010 and 2017 in Europe and Asia.
- - It analyzed data from 288 patients, revealing that 48% experienced recurrence within about 98 months, with 35% remaining disease-free at the 5-year mark.
- - Key negative predictors for long-term disease-free survival included multivisceral resection, tumor location in the pancreatic tail, poor differentiation, lymphovascular invasion, and perineural invasion, leading to the development of a predictive model with a good success rate.
In many cancers, a stem-like cell subpopulation mediates tumor initiation, dissemination and drug resistance. Here, we report that cancer stem cell (CSC) abundance is transcriptionally regulated by C-terminally phosphorylated p27 (p27pT157pT198). Mechanistically, this arises through p27 co-recruitment with STAT3/CBP to gene regulators of CSC self-renewal including MYC, the Notch ligand JAG1, and ANGPTL4.
