ABSTRACT
Objective The present research aimed to explore the relationship of serum CA19-9,CEA,CA125 and sICAM-1 concentration with the diagnosis valuation and tumor metastasis of pancreatic cancer.Methods Ninety pancreatic cancer patients in First Affiliated Hospital of Hebei North University from January 2014 to December 2016 were enrolled in this study.The concentrations of serum CA19-9,CEA,CA125 and sICAM-1 were assayed in different stage of pancreatic cancer patients.The concentrations of these parameters were also detected in metastasis patients and non-metastasis patients.In the same period,90 cases of health examination as contrd group.Measurement data were represented as ~ ± s.Comparison between groups was analyed using t test.single-factor analysis of variance (ANOVA) was used for comparison among groups,and the resuhs were compared by F test.The correlation analysis was performed by spearman method.Results The results showed that CA19-9/ β-actin (control group and Ⅰ / Ⅱ / Ⅲ/Ⅳ stage pancreatic cancer were 0.25 ± 0.03,0.27 ± 0.04,0.31 ± 0.06,0.38 ± 0.09,0.68 ± 0.10,respectively),CEA/β-actin (control group and Ⅰ / Ⅱ / Ⅲ/Ⅳ stage pancreatic cancer were 0.29 ±0.07,0.34 ±0.08,0.47 ±0.09,0.58 ±0.12,0.68 ±0.14,respectively),CA125/β-actin(control group and Ⅰ/Ⅱ/Ⅲ/Ⅳ stage pancreatic cancer were 0.31 ±0.05,0.36 ±0.07,0.55 ±0.13,0.58 ±0.14,0.63 ± 0.14,respectively),sICAM-1/β-actin (control group and Ⅰ/Ⅱ/ Ⅲ /Ⅳ stage pancreatic cancer were 0.34 ± 0.05,0.36 ± 0.08,0.41 ± 0.08,0.49 ± 0.10,0.58 ± 0.12,respectively) were higher in pancreatic cancer than control(P ＜0.05).The tumor metastasis group was higher than tumor un-metastasis group CA19-9/β-actin(un-metastasis group and metastasis group was 0.36 ± 0.09,0.58 ± 0.12),CEA/β-actin (un-metastasis group and metastasis group was 0.42 ± 0.09,0.61 ± 0.14),CA125/β-actin (un-metastasis group and metastasis group was 0.48 ± 0.09,0.60 ± 0.14),sICAM-1/β-actin (un-metastasis group and metastasis group was 0.42 ±0.09,0.52 ± 0.10) (P ＜ 0.05).The results showed that CA19-9,CEA,CA125 and sICAM-1 concentrations are positively (r value were 0.832,0.698,0.748 and 0.845) with the metastasis of pancreatic cancer patients while negatively with the prognosis (r value were-0.867,-0.832,-0.916 and-0.908) and clinical stage (r value were-0.815,-0.896,-0.798,and0.912) of pancreatic cancer patients.Conclusion CA19-9,CEA,CA125 and sICAM-1 concentrations are positively related with the metastasis of pancreatic cancer patients while negatively with the clinical stage and prognosis of pancreatic cancer patients.
ABSTRACT
Objective To study the value of CA19-9,s-ULBP2 and Dkk1 in the diagnosis of pancreatic cancer and the correlation. Methods From January 2016 to May 2017,56 patients with pancreatic cancer in our hospital were selected,45 healthy subjectsand 33 patients with benign pancreatic diseaseswere enrolled in this study.The differences of serum CA19-9,Dkk1 and s-ULBP2 expression and their relationship with clinicopatholog-ical parameters were compared between the three groups. The diagnostic value of CA19-9,s-ULBP2,Dkk1 and joint detection was analyzed.Results The serum levels of CA19-9,s-ULBP2 and Dkk1 in patients with pancreat-ic cancer were significantly higher than those in the benign pancreatic disease group and the healthy control group (P<0.05).CA19-9 and s-ULBP2 are related to TNM staging and histological differentiation,and CA19-9 is also related to tumor location.Joint test was higher than any of the individual indicators.Conclusion CA19-9,s-ULBP2 and Dkk1 are closely related to pancreatic cancer,and the combined detection of the three can improve the diag-nostic accuracy of pancreatic cancer.
ABSTRACT
Objective To study the expression of HIF-1αand and its correlation with gastric cancer recurrence, and to identify its prog-nosis evaluation in gastric cancer recurrence. Methods 80 patients with gastric cancer recurrence after radical surgery were selected as the observation group, and 50 patients without gastric cancer recurrence 5 or more than 5 years after surgery were selected as the control group. The immunohistochemical situation and expression of VEGF of the two groups were compared, and the correlation of HIF-1αand VEGF and gastric cancer recurrence were analyzed. Results The positive expression rate of HIF-1αand VEGF were 77. 50% and 73. 75% respectively in the observation group, which were significantly higher than 12. 00% and 10. 00% in the control group. Univariate analysis showed that the related indices such as degree of differentiation, depth of invasion, lymph node metastasis, vascular invasion, and TNM clinical stage were associated with VEGF expression and positive expression of HIF-1α. The Spearman correlation analysis showed that HIF-1α and VEGF was positively correlated (r=0. 458,P=0. 000). 1-year survival rate of HIF-1α-positive group was 45. 16%, and the average survival time was (8. 62 ± 2. 32) months, which was significantly lower than 77. 77% and (18. 96 ± 3. 14) months respectively in the negative group. Cox risk model analysis showed that HIF-1αand VEGF expression were high risk factors for gastric cancer recurrence. Conclusion HIF-1αand VEGF expression have a very colse correlation with gastric cancer recurrence, and it can be used as evaluation of gastric cancer recurrence and prognosis.
