Abstract:
Objective To investigate the correlation of fibulin 5(FBLN5)and Rho GTPase activating protein 4(ARHGAP4)in gastric cancer tissues and their relationship with the prognosis of patients.Methods One hundred gastric cancer patients admitted to the Department of General Surgery of Shijiazhuang First Hospital were selected for the study,and gastric cancer tissues＞1 cm from the tumor margin and paracancerous tissues 5 cm from the tumor margin were collected.Retrospective analysis of the relationship between FBLN5 and ARHGAP4 expression profiles and clinicopathological indices of gastric cancer,as well as their effects on survival,was performed with univariate and Cox regression analyses of the patients'clinical data.Immunohistochemical staining was used to detect the expression of FBLN5 and ARHGAP4.The relationship between the expression levels of different FBLN5 and ARHGAP4 and the survival time of patients.Results The positive expression rate of ARHGAP4 was lower than that of paracancerent tissues,and the positive expression rate of FBLN5 was higher than that of paracancerent tissues(P＜0.05).ARHGAP4 expression was associated with tumor site,Lauren's staging,lymph node metastasis,TNM stage,differentiation degree,CE,CA19-9,CA125,and immune score(P＜0.05);FBLN5 expression was associated with Lauren's staging,lymph node metastasis,TNM stage,differentiation degree,CE,CA19-9,CA125,and immune score(P＜0.05);Kaplan-Meier analysis showed that the 3-year cumulative survival rate of FBLN5 positive group was,which was lower than that of negative group(P=0.044).The 3-year cumulative survival rate of ARHGAP4 positive patients was higher than that of negative patients(P=0.021).Cox results showed that positive ARHGAP4 was protective factor for survival(P＜0.05).Conclusion The prognosis of patients in the FBLN5-positive group is worse than that in the negative group,high expression of FBLN5 is a risk factor for survival,and the prognosis of patients with ARHGAP4 negative group is better than that in the positive group,which are closely related to the development and prognosis of gastric cancer patients.
