ObjectiveTo summarize the influence and mechanism of visceral fat on the treatment and prognosis of gastric cancer patients.MethodLiteratures on the correlation and mechanism between visceral fat and treatment and prognosis of gastric cancer were collected and reviewed.ResultsHigh visceral fat may promote the incidence and progress of gastric cancer, and increase the incidence of complication of radical gastrectomy, including surgical site infection, pancreatic fistula, etc., as well as prolong the length of hospital stay. Reducing patients’ visceral fat level before operation could reduce the incidence of surgical complication. However, the persistent decrease of visceral fat level after operation may indicate poor prognosis. The effect of visceral fat on gastric cancer and its treatment was mainly due to the local chronic inflammation caused by excessive visceral fat tissue, the change of adipocytokine secretion, insulin resistance, and other mechanisms.ConclusionWe need to use visceral fat and other indicators to evaluate gastric cancer patients’ weight and body composition, in order to better guide the treatment and prognosis evaluation of gastric cancer.
ObjectiveTo summarize the research progress of relation between visceral fat and pancreatic cancer. MethodThe domestic and foreign literature on the accumulation of visceral fat, the potential mechanism of association between visceral fat and pancreatic cancer, the measurement of visceral fat, and the association of visceral fat with prognosis for pancreatic cancer in recent years was reviewed. ResultsThe accumulation of visceral fat was the result of multiple factors, including age, gender, sex hormones, endocannabinoid system, etc. A variety of adipokines secreted by visceral fat played a crucial role in the occurrence and development of pancreatic cancer, which played a pro-tumor and anti-tumor effects mainly through a variety of different signal pathways. ConclusionsIn clinical treatment, the quality of life and prognosis of patients with pancreatic cancer can be improved by reducing visceral fat mass by adjusting diet, physical training, and other methods, as well as intervening the action signal pathways of various adipokines without affecting the disease progression.
