Article Abstract

A 54-year-old woman was presented with the intraabdominal mass to our hospital. Abdominal CT showed 22 cm tumor of the stomach with invasion to the pancreas and the spleen. Upper GI endoscopy showed submucosal tumor at the stomach body, and endoscopic US showed low echoic tumor. The tumor was diagnosed as gastric GIST by biopsy with c-kit positive cells. After 4 months of neoadjuvant therapy with imatinib, she underwent total gastrectomy, distal pancreatectomy and splenectomy. Histopathologically, there were no viable tumor cells in the resected specimen. The patient has no evidence of recurrence at 8 months post operation.

Gastric cancer (GC) is the third leading cause of cancer mortality globally, often presenting with insidious symptoms that lead to late-stage diagnoses, underscoring the critical need for innovative diagnostic and therapeutic strategies. One such avenue is the exploration of ferroptosis, a regulated form of cell death implicated in various pathological conditions and malignancies. In this study, we demonstrate that brucine, an alkaloid derived from Strychnos nux-vomica, exerts significant antitumor effects on GC cells both in vitro and in vivo.

Background And Objective: CD68 plays a crucial role in promoting phagocytosis. However, its expression level, prognostic value and the correlations with tumor-infiltrating immune cells (TIICs) or common tumor immune checkpoints (TICs) in human digestive system cancers (DSC) remain poorly understood. This study aims to investigate the expression levels, prognostic significance, and clinical implications of CD68, as well as its correlations with six TIICs and four common TICs in DSC.

Background: Results from the GEMSTONE-303 trial indicate that compared with placebo plus capecitabine and oxaliplatin (PLA-CAP), sugemalimab plus capecitabine and oxaliplatin (SUG-CAP) as first-line therapy provides clinical benefits for patients with advanced gastric or gastroesophageal junction (G/GEJ) adenocarcinoma with programmed cell death ligand 1 (PD-L1) combined positive score (CPS) ≥5. However, the addition of sugemalimab increases medical costs. This study aimed to assess the cost-effectiveness of SUG-CAP vs.
