Multicenter Study
Impact of Neoadjuvant Therapy for Pancreatic Cancer: Transatlantic Trend and Postoperative Outcomes Analysis.
The introduction of modern chemotherapy a decade ago has led to increased use of neoadjuvant therapy (NAT) in patients with pancreatic ductal adenocarcinoma (PDAC). A recent North American study demonstrated increased use of NAT and improved operative outcomes in patients with PDAC. The aims of this study were to compare the use of NAT and short-term outcomes in patients with PDAC undergoing pancreatoduodenectomy (PD) among registries from the US and Canada, Germany, the Netherlands, and Sweden. ⋯ NAT before PD for pancreatic cancer varied widely among 4 Western audits yet increased by 26% during 3 years. NAT was associated with improved short-term outcomes.

Receipt of guideline-concordant treatment (GCT) is associated with improved prognosis in foregut cancers. Studies show that patients living in areas of high neighborhood deprivation have worse healthcare outcomes; however, its effect on GCT in foregut cancers has not been evaluated. We studied the impact of the area deprivation index (ADI) as a barrier to GCT. ⋯ Residence in an area of high deprivation predicts nonreceipt of GCT. This is due to multiple individual- and system-level barriers. Identifying these barriers and developing effective interventions, including community outreach and collaboration, leveraging telehealth, and increasing oncologic expertise in underserved areas, may improve access to GCT.

Noninvasive, precision monitoring of hepatocellular carcinoma (HCC) treatment efficacy would greatly facilitate personalized therapy and improve patient outcomes. We hypothesize that quantifying methylated circulating tumor DNA (ctDNA) can be used to effectively monitor HCC burden without the need for biopsy. ⋯ These findings indicate that ctDNA methylation scores can effectively evaluate changes in tumor burden without the need for tumor biopsy.

At the 2023 ATLS symposium, the priority of circulation was emphasized through the "x-airway-breathing-circulation (ABC)" sequence, where "x" stands for exsanguinating hemorrhage control. With growing evidence from military and civilian studies supporting an x-ABC approach to trauma care, a prehospital advanced resuscitative care (ARC) bundle emphasizing early transfusion was developed in our emergency medical services (EMS) system. We hypothesized that prioritization of prehospital x-ABC through ARC would reduce in-hospital mortality. ⋯ This is the first analysis to demonstrate a prehospital survival benefit of x-ABC in this subset of patient with severe injury and hemorrhagic shock. Standardization of prehospital x-ABC management in this patient population warrants special consideration.
