Background: Gastric cancer (GC) is a globally important disease. It is the 5th most common malignancy and the 4th most common cause of death from cancer in the world. Patients with GC are often at an advanced stage when they are first diagnosed, and their overall prognosis is poor due to locally advanced and distant metastasis. This study sought to establish a predictive model of GC distant metastasis and survival that can be used to guide individualized treatment.Methods: Patients diagnosed with GC from the Surveillance, Epidemiology, and End Results database were enrolled in the study. Univariate and multivariate logistic regression analyses were used to identify risk and prognostic factors for GC patients with distant metastasis. The factors were then used to construct nomograms to predict the probability of distant metastasis and the survival time of GC patients. Receiver operating characteristic (ROC) curve and decision curve analyses were used to verify the prediction ability of the nomograms. Results:We established a comprehensive nomogram to predict the survival time of GC patients and 4 nomograms to predict distant metastasis. Nomograms could help oncologists to formulate treatment strategies and provide hospice care under an overall management model.Conclusions: Establishing a prediction model for distant metastasis and the survival of GC patients is of great clinical significance. The prediction of distant metastasis could help clinicians to make individualized assessments of patients and formulate individualized examination measures. Survival prediction models could help oncologists to formulate good treatment strategies and provide hospice care.

PurposeUniversal germline testing in patients with colorectal cancer (CRC) with a multigene panel can detect various hereditary cancer syndromes. This study was performed to understand how to choose a testing panel and whether the result would affect clinical management.MethodsWe prospectively enrolled 486 eligible patients with CRC, including all patients with CRC diagnosed under age 70 years and patients with CRC diagnosed over 70 years with hereditary risk features between November 2017 and January 2018. All participants received germline testing for various hereditary cancer syndromes.ResultsThe prevalence of germline pathogenic variants (PVs) in cancer susceptibility genes was 7.8% (38/486), including 25 PVs in genes with high-risk CRC susceptibility (the minimal testing set) and 13 PVs in genes with moderate-risk CRC susceptibility or increased cancer risk other than CRC (the additional testing set). All the clinically relevant PVs were found in patients diagnosed under age 70 years. Among them, 11 patients would not have been diagnosed if testing reserved to present guidelines. Most (36/38) of the patients with PVs benefited from enhanced surveillance and tailored treatment. PVs in genes from the minimal testing set were found in all age groups, while patients carried PVs in genes from the additional testing set were older than 40 years.ConclusionUniversal germline testing for cancer susceptibility genes should be recommended among all patients with CRC diagnosed under age 70 years. A broad panel including genes from the additional testing set might be considered for patients with CRC older than 40 years to clarify inheritance risks.Trial registration numberNCT03365986.

In recent years, LNK, an adapter protein, has been found to be associated with metabolic diseases, including hypertension and diabetes. We found that the expression of LNK in human adipose tissue was positively correlated with serum glucose and insulin in obese people. We examined the role of LNK in insulin resistance and systemic energy metabolism using LNK-deficient mice ( LNK -/- ). With consumption of a high-fat diet, wild type (WT) mice accumulated more intrahepatic triglyceride, higher serum triglyceride (TG), free fatty acid (FFA) and high sensitivity C-reactive protein (hsCRP) compared with LNK -/- mice. However, there was no significant difference between LNK -/- and WT mice under normal chow diet. Meanwhile, glucose transporter 4 (GLUT4) expression in adipose tissue and insulin-stimulated glucose uptake in adipocytes were increased in LNK -/- mice. LNK -/- adipose tissue showed activated reactivity for IRS1/PI3K/Akt/AS160 signaling, and administration of a PI3K inhibitor impaired glucose uptake. In conclusion, LNK plays a pivotal role in adipose glucose transport by regulating insulin-mediated IRS1/PI3K/Akt/AS160 signaling.

Background: This study sought to test the effectiveness of EVOSKIN ® Palm and sole moisturizing cream (PSMC) in preventing and treating hand-foot syndrome (HFS) during capecitabine chemotherapy.Methods: Stage II/III colorectal cancer patients receiving capecitabine adjuvant chemotherapy were randomly allocated to receive either EVOSKINPSMC or physiological saline treatments for their hands and feet. Treatment was initiated along with adjuvant chemotherapy and continued till the end of chemotherapy.Participants' skin responses were evaluated every 3weeks.Results: During the study, 51 participants in the EVOSKIN PSMC group and 54 participants in the physiological saline group completed at least three cycles of capecitabine chemotherapy. The total incidence of HFS in the EVOSKIN PSMC group was lower than that in the physiological saline group (56.8% vs. 75.9%, P=0.006), as was the incidence of Grade 3/4 HFS (6.0% vs. 18.5%, P=0.011). The incidence of HFS became significant after 6weeks of chemotherapy. Further, the incidence of severe HFS was significant from as early as 3weeks after the commencement of chemotherapy despite the use of EVOSKIN PSMC to manage the condition. Notably, the incidence of Grade 1/2 HFS was not statistically significant between the two groups (26/51 vs. 32/54, 52.0% vs. 59.2%, P=0.194). Conclusions:The incidence of severe HFS among individuals using oral capecitabine can be reduced by the prophylactic treatment of EVOSKIN PSMC, this treatment is reasonable and acceptable for patients with capecitabine chemotherapy.
