Dose-Escalated SBRT for Borderline and Locally Advanced Pancreatic Cancer: Resectability Rate and Pathological Results of a Multicenter Prospective Study.
Cancers (Basel)
January 2025
Canarian Insitute for Cancer Research, 380204 San Cristobal de La Laguna, Spain.
Objective: We demonstrated for the first time the safety and feasibility of escalating up to 55 Gy/11 Gy/fr/5fr in borderline (BRPC)/unresectable locally advanced pancreatic cancer (LAPC), using the standard LINAC platform. The aim of the present study is to assess for the first time the impact of this high-dose neoadjuvant stereotactic ablative radiotherapy (SABRT) protocol on tumor resectability and pathological responses.
Materials/methods: From June 2017 to December 2022, patients with BRPC/LAPC were treated with neoadjuvant chemotherapy (ChT) and SABRT-escalated doses of SIB at 45 Gy, 50 Gy, and up to 55 Gy (BED ≥ 100).
The choice of adjuvant radiotherapy in pancreatic cancer patients after up-front radical surgery.

Department of Radiation Oncology, The First Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China.
Background: The role of adjuvant radiotherapy in pancreatic cancer following radical surgery remains a subject of of controversy. This study aimed to more accurately screen pancreatic patients who benefit from adjuvant radiotherapy.
Methods: Clinicopathologic characteristics of patients with resectable pancreatic cancer were collected from the Surveillance, Epidemiology, and End Results (SEER) database (2004-2015).
Mcl-1 is a Gatekeeper Molecule to Regulate the Crosstalk Between Ferroptotic Agent-Induced ER Stress and TRAIL-Induced Apoptosis.

We previously reported that ferroptosis interplays with apoptosis through the integration of two independent pathways: the endoplasmic reticulum (ER) stress signaling pathway and the mitochondria-dependent apoptotic signaling pathway. In this study, we investigated a potential gatekeeper molecule, Mcl-1, between the two signal transduction pathways. Morphology studies and cell death analyses confirmed that a combination treatment of ferroptotic agent erastin (ERA) and apoptotic agent TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) synergistically enhances TRAIL-induced apoptosis in human pancreatic adenocarcinoma BxPC3 and human colorectal carcinoma HCT116 cells.

Department of Chemical and Biological Engineering, Colorado School of Mines, Golden, CO, USA.
Type 1 diabetes is an autoimmune disease characterised by the destruction of pancreatic beta cells, resulting in lifelong insulin dependence. Although exogenous insulin can maintain glycaemic control, this approach does not protect residual or replacement pancreatic beta cells from immune-mediated death. Current therapeutics designed to protect functional beta cell mass or promote beta cell proliferation and regeneration can have off-target effects, resulting in higher dose requirements and adverse side effects.

Objectives: Choledocholithiasis is the leading cause of biliary pancreatitis and biliary sepsis. Endoscopic retrograde cholangiopancreatography (ERCP) is considered a minimally invasive treatment for choledocholithiasis. However, diagnostic ERCP should be avoided.
