  • Diagnostic and prognostic value of TRIM21 in gastric cancer

    ObjectiveTo investigate the expression of tripartite motif 21 (TRIM21) in gastric cancer tissues and its relationship with clinical pathological characteristics and clinical prognosis.MethodsPublic database was used to analyze the expression level of TRIM21 in gastric cancer tissues and the relationship between its expression and clinical prognosis. Gene set enrichment analysis (GSEA) was used to analyze the signaling pathways that TRIM21 might participate in. The expressions of TRIM21 in 80 gastric cancer tissues and 30 para-cancer tissues were detected by immunohistochemical staining, and the relationship between TRIM21 expression and clinicopathologic characteristics was analyzed.ResultsTRIM21was significantly low-expression in gastric cancer tissues, and the clinical prognosis of patients with low TRIM21 expression was significantly worse (P<0.05); GSEA showed that TRIM21 was involved in the regulation of helper T cell differentiation in gastric cancer patients (P<0.000 1, FDR<0.000 1).ConclusionsTRIM21 is poorly expressed in gastric cancer tissues and indicates the poor clinical prognosis. Moreover, TRIM21 is involved in the regulation of helper T cell differentiation and has a negative regulatory effect on the occurrence and development of gastric cancer.

  • Value of preoperative neutrophil-to-lymphocyte ratio combined with CA19-9 in evaluating prognosis of patients with pancreatic head carcinoma

    ObjectiveTo explore value of preoperative neutrophil-to-lymphocyte ratio (NLR) combined with carbohydrate antigen 19-9 (CA19-9) in evaluating prognosis for patients with pancreatic head carcinoma.MethodsThe clinical data of patients with pancreatic head carcinoma underwent radical pancreaticoduodenectomy in the Lanzhou University Second Hospital from February 2011 to August 2017 were retrospectively analyzed. The preoperative serum albumin (ALB), CA19-9, NLR, carcino-embryonic antigen (CEA), alpha-fetoprotein (AFP), N stage, tumor differentiated degree, and other indicators were recorded and the patient’s overall survival was recorded. Linear correlation analysis was used to examine the association of NLR with serum CA19-9. The receiver operating characteristic (ROC) curve was used to calculate the cutoff values of NLR and CA19-9 corresponding to the overall survival rate of 2-year. Kaplan-Meier method was used for survival analysis. Cox proportional hazards regression model was used to evaluate the prognostic value of preoperative CA19-9 and NLR.Results① A total of 121 patients were enrolled in this study. There was no significant correlation between the preoperative serum CA19-9 and NLR (r=0.100 05, P=0.272 9). ② Multivariate analysis showed that higher NLR, higher CA19-9 level, higher N stage, and lower tumor differentiation were the risk factors for overall survival of pancreatic head carcinoma (P<0.05). ③ The cutoff values of CA19-9 and NLR in evaluating the 2-year overall survival rate were 123.3 U/mL and 2.34 respectively by the ROC curve analysis, the area under ROC curve of CA19-9, NLR, and CA19-9 combined with NLR were 0.763, 0.686, and 0.823, respectively. ④ The proportions of patients with CEA≥5 μg/L and ≥N1 stage were higher in the patients with CA19-9≥123.3 U/mL as compared with patients with CA19-9<123.3 U/mL (P<0.05); The proportions of patients with preoperative serum ALB level <35 g/L and CEA≥5 μg/L, ≥N1 stage, and poor differentiation were higher in the patients with NLR≥2.34 as compared with the patients with NLR<2.34 (P<0.05). ⑤ Kaplan-Meier survival analysis showed that patients with CA19-9≥123.3 U/mL and NLR≥2.34 had worse overall survival than those patients with CA19-9<123.3 U/mL and NLR<2.34 (HR=3.599, P<0.01; HR=2.506, P<0.01). The patients with CA19-9≥123.3 U/mL and NLR≥2.34 (n=42), CA19-9≥123.3 U/mL or NLR≥2.34 (n=48), CA19-9<123.3 U/mL and NLR<2.34 (n=31) had better overall survival in turn (overall and between groups, all P<0.01).ConclusionPreoperative serum CA19-9 combined with NLR has an important value in evaluating prognosis for patients with pancreatic head carcinoma.
