Article Abstract
Pancreatic cancer is a devastating disease with proclivity for early metastasis, which accounts for its poor prognosis. The clinical problem of pancreatic cancer is its resistance to conventional therapies, such as chemotherapy or radiation. Based upon these challenges, the focus of research on pancreatic cancer has shifted gradually towards the tumor microenvironment. The cancer microenvironment consists of various components, including fibroblasts, endothelial cells, immune cells, and endocrine cells, that interact with each other, and with the cancer cells in a complex fashion. Evidence is accumulating that the cancer microenvironment plays an active role in disease progression, and efforts are being made to target this interplay between cancer cells and host cells, to improve the prognosis of the disease. In the present review, we describe the cellular microenvironment of pancreatic ductal adenocarcinoma (PDA), the major type of pancreatic cancer. Our hope is that a better understanding of the cellular microenvironment of PDA will eventually lead to better treatments for this disease.

Oral Lactoferrin-Responsive Formulation Anchoring around Inflammatory Bowel Region for IBD Therapy.
Adv Healthc Mater
December 2024
Department of Oncology, The Second Affiliated Hospital, Medical School of Xi'an Jiaotong University, Xi'an, Shaanxi, 710061, China.
Oral formulation is the ideal treatment method for inflammatory bowel disease (IBD) therapy, but the mucosal damage and diarrhea symptoms impede the drug retention around the inflammatory region, severely limiting IBD therapeutic efficacy. To address this, an oral astaxanthin (Ast) precise delivery formulation is developed with the selective Ast anchoring around the inflammatory region by the novel lactoferrin (LF)-responsive flocculation. This formulation also heightens the apparent solubility of Ast with the minimized edible safety risks for the edible raw materials.

Department of Internal Medicine, College of Medicine, National Taiwan University, Taipei, Taiwan.
Background/aims: Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is an essential tool for tissue acquisition in solid pancreatic tumors. Rapid on-site evaluation (ROSE) by cytologists ensures diagnostic accuracy. However, the universal application of the ROSE is limited by its availability.

December 2024
Chongqing Key Laboratory of Intelligent Medicine Engineering for Hepatopancreatobiliary Diseases, Chongqing General Hospital, Chongqing University, Chongqing, China.
Background: Laparoscopic radical antegrade modular pancreatosplenectomy combined with celiac axis resection and portal vein reconstruction is a new procedure for the treatment of pancreatic cancer. This surgical technique may offer patients with pancreatic cancer involving the portal vein and celiac axis an opportunity for radical surgical resection. We aim to evaluate the short- and long-term efficacy and describe the surgical details of this technique.

December 2024
Division of Hepato-biliary-pancreatic Surgery, Shizuoka Cancer Center, 1007, Shimo-Nagakubo, Sunoto-Nagaizumi, Shizuoka, 411-8777, Japan.
Background: This study compared short- and mid-term outcomes of hemihepatectomy (HH) and pancreatoduodenectomy (PD) in patients with extrahepatic cholangiocarcinoma, focusing on surgical outcomes, body composition, and nutritional status.
Method: A retrospective review was conducted to assess short-term outcomes, including operative time, blood loss, complications, and mortality. Body composition and nutritional parameters were analyzed preoperatively and 1 year postoperatively.
Significance of frailty in mortality and complication after hepatectomy for patients with liver cancer: a systematic review and meta-analysis.
HPB (Oxford)
December 2024
Department of Hepatobiliary and Pancreatic Surgery, The First Hospital of China Medical University, Shenyang, 110001, China.
Background: Frailty has been associated with increased mortality and complications among liver cancer patients. However, the frailty prevalence and outcomes in frail populations with primary liver cancer have not been systematically validated.
Methods: Embase, PubMed, Scopus, and Web of Science were searched for eligible studies that explored the prevalence and impact of frailty in liver cancers from inception until October 26, 2023.
