RESUMO
Patients with gastric cancer often have different degrees of dyslipidemia, and the level of lipid changes is closely related to the occurrence, development and prognosis of gastric cancer. The mechanism of lipid metabolism in gastric cancer has also attracted much attention, and it may be related to the reverse cholesterol transport function, antioxidant and anti-inflammatory properties of high-density lipoprotein cholesterol. In addition, statins may reduce the risk of gastric cancer and associated mortality. Further research on the correlation between blood lipid levels and gastric cancer is aimed to provide new ideas for the future prevention and precision diagnosis and treatment of gastric cancer.
RESUMO
Although targeted, immune and other therapeutic strategies have become the first-line standard therapy for patients with advanced lung cancer, acquired drug resistance is still inevitable in most cases. The advent of antibody-drug conjugates (ADC) provides a new choice. ADC is a new anticancer drug formed by the coupling of targeted anti-tumor monoclonal antibodies and cytotoxic drugs. Compared with chemotherapeutic drugs, ADC has the advantages of high tolerance, accurate target recognition and little effect on non-cancer cells, and has shown good clinical benefits in the treatment of a variety of malignant tumors. This article reviews the application of ADC in advanced non-small cell lung cancer.
RESUMO
Objective:To explore the effects of myosteatosis and blood glucose (BG) on postoperative complications in non-diabetic gastric cancer patients receiving supplemental parenteral nutrition (SPN) after gastrectomy.Methods:Patients who underwent radical gastrectomy between March 2017 and June 2021 in the Department of Surgical Oncology, the First Hospital of Lanzhou University were included in this study. Various preoperative inflammatory and nutritional indicators, including skeletal muscle metrics at the third lumbar level on CT, were collected retrospectively. Postoperative BG within 3 days and complications within 30 days were monitored. Patients were divided into two groups according to the presence or absence of myosteatosis (assessed via skeletal muscle density [SMD]) and the differences in postoperative BG and complication incidence were compared. Mediation model was used to analyze the mediating effect of BG in the association between SMD and postoperative complications.Results:A total of 357 patients were included in the study. Compared with the 299(83.8%) patients without myosteatosis , the incidence of hyperglycemia, mean BG, maximal BG, and BG fluctuation while on SPN in the 58(16.2%) patients with myosteatosis were higher, and the comprehensive complication index (CCI) and the incidence of complication were higher ( P<0.05). More importantly, BG showed the mediation effect of -0.0892 in the effect of SMD on CCI ( P<0.05), with the effect size of 19.3％. Conclusion:Myosteatosis and postoperative hyperglycemia are associated with higher incidence of complications, and BG plays an intermediary role in the association between myosteatosis and CCI.
