P2X7 receptor (P2X7R) plays a role in regulating tumor progression, but it is unclear whether P2X7R affects the pathological characteristics of patients with gastric cancer and the activity of gastric cancer cells. Therefore, this study preliminarily investigated the relationship between P2X7R and clinicopathological features of patients with gastric cancer, and further explored the effect of P2X7R on the proliferation, migration and invasion of gastric cancer cells through functional experiments. The results showed that P2X7R was highly expressed in gastric cancer tissues and gastric cancer cells. High expression of P2X7R was closely related to lymphatic metastasis, vascular invasion and Tumor-Node-Metastasis (TNM) stage in patients with gastric cancer. High expression of P2X7R predicted poor overall survival in patients. Moreover, the activation of P2X7R by ATP and its analogue BzATP increased the calcium current of gastric cancer cells, enhanced YF actin stress and cell viability, and promoted the proliferation, migration and invasion of gastric cancer cells. While P2X7R antagonists (A438079 and AZD9056) inhibited the proliferation, migration and invasion of gastric cancer cells induced by ATP. Therefore, the data obtained in this experiment suggest that P2X7R may be another potential molecular target for the prevention and treatment of gastric cancer.

Defining Textbook Outcomes for Minimally Invasive Surgical Resection of Small Gastrointestinal Stromal Tumors (GIST) of the Stomach.
Ann Surg Oncol
January 2025
Department of Surgery, University of California San Diego School of Medicine, San Diego, CA, USA.
Background: Textbook outcome (TO) has been utilized to assess the quality of surgical care. This study aimed to define TO rates for minimally invasive gastric gastrointestinal stromal tumor (GIST) resections in a bi-institutional cohort.
Methods: Patients with gastric GIST (≤ 5 cm) who underwent laparoscopic or robotic resection (January 2014 to January 2024) were retrospectively identified from two GIST centers.

Purpose: The study aimed to compare the diagnostic accuracy of Ga-DOTA-FAPI-04 (Ga-FAPI) and F-FDG PET/CT for peritoneal carcinomatosis (PC) in patients with various types of cancer.
Methods: The study enrolled 113 patients with suspected peritoneal malignancy, each of whom underwent Ga-FAPI and F-FDG PET/CT scans. Lesions in all patients were confirmed through pathology or radiological follow-up.

Objective: The role of intraoperative radiation therapy (IORT) in the management of resectable pancreatic cancer (RPC) remains unclear. To date, the application of IORT using a low-energy X-ray source has not been extensively investigated. Therefore, this study was conducted to evaluate the safety and efficacy of IORT using a 50 kV X-ray source in treating RPC.
