[Expert consensus on integrated medicine for tumor-related gastric injury and protection in China (2024 edition)].

Neoplasm is one of the major causes of harm to human health. With the development of integrated medicine, more experts have begun to pay attention to tumor-related damage, among which gastric injury is common and seriously affects the quality of life of patients. The stomach is richly supplied with blood and nerves. Tumor treatment methods such as medication, surgery, and interventional therapy can impair its barrier function. Additionally, the tumor itself can harm the stomach through various mechanisms, primarily manifesting as symptoms like gastritis, erosion, ulceration, bleeding, and perforation. These conditions significantly affect the patient's quality of life and pose a serious threat to life.At present, the mechanisms of gastrointestinal tumors and other systemic tumors causing gastric injury are unclear, and there is a lack of relevant clinical and basic research. The diagnostic criteria and protective measures need to be supplemented and improved. To enhance the understanding of tumor-related gastric injuries and their management among professionals in related fields and to guide clinical practice, this expert consensus has been refined and formulated under the integrated medical concepts and based on the previous guidelines of the Chinese Anti-Cancer Association (CACA). It summarizes various tumor-related gastric injuries and protective treatment strategies, aiming to provide clinicians in oncology with a reference to address and prevent gastric injuries during the treatment of systemic diseases, thereby laying a foundation for further in-depth research in the future.
