Association between degree of Helicobacter pylori infection with serum pepsinogen and tumor markers related with gastric cancer / 国际检验医学杂志

ABSTRACT

Objective To study the relationship of Helicobacter pylori(Hp)infection degree with serum pepsinogen(PG)and the tumor markers related with gastric cancer .Methods Totally 342 cases of health physical check‐up in our hospital from January to June 2015 were selected .13 C‐UBT was performed to evaluate the Hp infection and infection severitys .The level of serum PG was detected by ELSIA and the levels of tumor markers were detected by luminescence immunoassay .Then the results were statistically analyzed with the SPSS statistical software .Results The positive rate of Hp in 342 research subjects was 49 .42% ,and there was no difference between the male and the female groups(P>0 .05) .The level of serum pepsinogen Ⅰ (PGⅠ )and pepsinogen Ⅱ (PGⅡ)in the Hp(+ + )and Hp(+ + + )groups was significantly higher than that in the Hp negative group ,while the PGⅠ /PGⅡ lev‐el was significantly lower than that in the negative group (P<0 .05) .The level of carbohydrate antigen 724(CA724)and carcino‐em‐bryonic antigen(CEA)had the statistical difference between the Hp(+ + + ) group and the Hp negative group(P= 0 .040 ,P=0 .010) .The Pearson correlation analysis displayed that Hp infection was related with PG Ⅰ ,PGⅡ ,PGⅠ /PGⅡ ,CA724 and CEA . There was a positive correlation between PG Ⅱ and CA50)(r=0 .116 ,P=0 .032);there was a negative correlation between PG Ⅰ /PGⅡ and CA50(r= -0 .193 ,P=0 .000) .Conclusion The combined detection of Hp ,PG and tumor markers could be used as one of methods for screening benign and malignant gastric diseases in the healthy physical check‐up population ,which has an important value for the prevention and intervention of related disease occurrence and development .
