Since 1992, we have treated 43 patients with head and neck tumors by superselective intra-arterial infusion chemotherapy (SIIC) via femoral artery. In 8 patients among then, operation was performed thereafter with/without radiation therapy (RT). CDDP and/or CBDCA were utilized as the chemotherapeutic modality. Only SIIC or RT showed Grade (Gr.) 0-2b pathological effects on Oboshi-Shimosato classification scheme, while a combination of SIIC and RT exhibited Gr. 2b-4 pathological effects. We conclude that a combination of SIIC and RT was most effective and had induced degeneration or necrotic changes in the tumor tissue.

Safety of Cerebral Intra-Arterial Chemotherapy for the Treatment of Malignant Brain Tumours.

: Cerebral intra-arterial chemotherapy (CIAC) has been demonstrated to achieve tumoricidal concentrations in cerebral tumour cells that are otherwise unachievable due to the presence of the blood-brain barrier. In this study, we sought to analyze the safety of CIAC in a cohort of patients treated at the Centre intégré universitaire de santé et de services sociaux de l'Estrie-Centre hospitalier universitaire de Sherbrooke (CIUSSS-CHUS). : Treatments consisted of monthly CIAC.

Background: Pancreatic cancer is one of the most malignant tumors with an inferior prognosis. This study aims to determine the prognostic significance of immune-inflammatory scores and coagulation indices in patients with metastatic pancreatic cancer(MPC) and develop a predictive nomogram.
Methods: This study retrospectively analyzed the clinical data of 384 patients with MPC who underwent intra-arterial infusion chemotherapy (IAIC).
The Prognostic Value of CRP/Alb Ratio in Predicting Overall Survival for Hepatocellular Carcinoma Treated with Transcatheter Intra-Arterial Therapy Combined with Molecular-Targeted Agents and PD-1/PD-L1 Inhibitors.

Department of Interventional Therapy, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, 100021, People's Republic of China.
Purpose: This study aimed to evaluate the prognostic value of C-reactive protein to albumin (CRP/Alb) ratio in hepatocellular carcinoma (HCC) treated with transcatheter intra-arterial therapy combined with molecular targeted agents (MTAs) and programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors.
Methods: Medical records of 271 consecutive patients with HCC receiving this combination therapy in China between 2019 and 2023 were retrospectively analyzed. Prognostic factors for progression-free survival (PFS) and overall survival (OS) were identified using univariate and multivariate Cox regression analyses.
Phospholipid Nanoparticles: A Novel Colloid for Blood Volume Replacement, Reanimation, and Organ Protection in Hemorrhagic Shock.

: Exsanguination is a leading cause of preventable death in military and civilian settings due to extensive blood loss and hemorrhagic shock, which trigger systemic effects such as impaired tissue perfusion, hypoxia, inflammation, and multi-organ dysfunction. Standard resuscitation restores blood volume but fails to address critical aspects of hemorrhagic shock, including inflammation, coagulopathy, and reperfusion injury. To address these limitations, novel phospholipid nanoparticle (PNP)-based resuscitative fluids, VBI-S and VBI-1, were developed to modulate nitric oxide (NO) levels, improving hemodynamic stability, tissue oxygenation, and reducing inflammatory injury.

Article Synopsis
- The study focused on developing an optimized lidocaine dosing regimen for obese patients during surgery, highlighting the need for more effective pain management.
- Researchers gathered data from 30 patients, measuring plasma levels of lidocaine and its metabolites to create a pharmacokinetic model.
- The findings suggested that current dosing was often inadequate, but an adjusted regimen could improve the likelihood of reaching therapeutic drug concentrations.
