AI Article Synopsis

  • Gastric cancer is highly deadly due to its frequent metastasis, with the Rho/ROCK signaling pathway being a key player in regulating cancer cell movement and invasion.
  • Recent studies highlight that tumor cells can move in two ways—mesenchymal and amoeboid—which can switch based on conditions, emphasizing the importance of actin cytoskeleton in metastasis.
  • The review explores Rho GTPases and ROCK signaling mechanisms, and discusses the potential for therapies aimed at targeting the Rho/ROCK pathway in gastric cancer treatment.

Article Abstract

Gastric cancer is one of the most frequent and lethal malignancies worldwide because of high frequency of metastasis. Tumor cell motility and invasion play fundamental roles in cancer metastasis. Recent studies have revealed that the Rho/Rho-associated protein kinases (ROCK) pathway plays a critical role in the regulation of cancer cell motility and invasion. In addition, the Rho/ROCK pathway plays important roles in invasion and metastasis on the basis of its predominant function of cell cytoskeletal regulation in gastric cancer. According to the current understanding of tumor motility, there are two modes of tumor cell movement: mesenchymal and amoeboid. In addition, cancer cell movement can be interchangeable between the mesenchymal and amoeboid movements under certain conditions. Control of cell motility through the actin cytoskeleton creates the potential for regulating tumor cell metastasis. In this review we discuss Rho GTPases and ROCK signaling and describe the mechanisms of Rho/ROCK activity with regard to motility and metastasis in gastric cancer. In addition, we provide an insight of the therapeutic potential of targeting the Rho/ROCK pathway.

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.

Safety and efficacy of intraoperative radiation therapy using a low-energy X-ray source for resectable pancreatic cancer: an interim evaluation of an ongoing prospective phase II study.

Cancer Biol Med

January 2025

Department of Pancreatic Cancer, Tianjin Medical University Cancer Institute & Hospital, National Clinical Research Center for Cancer, Key Laboratory of Cancer Prevention and Therapy, Tianjin, Tianjin's Clinical Research Center for Cancer, Tianjin 300060, China.

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.
