In treating advanced gastric cancer cases, 100 mg/m2 of cisplatin (CDDP) was given to such patients by means of a 24 hr continuous iv infusion once a month. This was in addition to daily UFT chemotherapy with an oral administration of UFT at a dose of 200 mg/m2 twice a day before meals. In this paper, two patients who achieved an objective tumor response to this UFT/CDDP chemotherapy are discussed. It was felt that this treatment was not likely to induce either leukocytopenia or thrombocytopenia. With regard to this drug combination, it has been reported that a remarkable, synergistic, antitumoral activity of combined 5-fluorouracil and cisplatin was demonstrated against L-1210 leukemia in BDF1 mice.

Introduction: Advances in treatment strategies for gastric and esophageal cancer have led to improved long-term outcomes, however the local and systemic effects of tumor growth, neoadjuvant therapies and surgery, results in specific nutritional challenges. Comprehensive nutritional evaluation and support represents a core component of multidisciplinary holistic care for this patient population.
Areas Covered: This review provides a detailed overview of the nutritional challenges in gastric and esophageal cancer, with a focus on malignant obstruction, preoperative optimization and nutrition in survivorship.

Endoscopic management of benign pancreaticobiliary disorders encompasses a range of procedures designed to address complications in gallstone disease, choledocholithiasis, and pancreatic disorders. Acute cholecystitis is typically treated with cholecystectomy or percutaneous drainage (PT-GBD), but for high-risk or future surgical candidates, alternative decompression methods, such as endoscopic transpapillary gallbladder drainage (ETP-GBD), and endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD), are effective. PT-GBD is associated with significant discomfort as well as variable adverse event rates.

Studies on the gastric microbiota associated with gastric precancerous lesions remain limited. This study aimed to profile the gastric mucosal microbiota in patients with -negative precancerous lesions. Gastric mucosal samples were obtained from 67 -negative patients, including those with chronic gastritis (CG), intestinal metaplasia (IM), and dysplasia.

In the field of digestive system tumor research, spatial transcriptomics technologies are used to delve into the spatial structure and the spatial heterogeneity of tumors and to analyze the tumor microenvironment (TME) and the inter-cellular interactions within it by revealing gene expression in tumors. These technologies are also instrumental in the diagnosis, prognosis, and treatment of digestive system tumors. This review provides a concise introduction to spatial transcriptomics and summarizes recent advances, application prospects, and technical challenges of these technologies in digestive system tumor research.
