Serum tumor markers (carcinoembryonic antigen, carbohydrate antigen 19-9, carbohydrate antigen 72-4, carbohydrate antigen 24-2, ferritin) and gastric cancer prognosis correlation

BACKGROUND Gastric cancer is a kind of malignant tumor which is prevalent all over the world.Although some progress has been made in the treatment of gastric cancer,its prognosis is still not optimistic,so it is of great significance to find reliable prog-nostic indicators to guide the treatment and management of patients with gastric cancer.AIM To explore the relationship between serum levels of five biomarkers[carcinoem-bryonic antigen(CEA),carbohydrate antigen(CA)19-9,CA72-4,CA24-2,and ferritin]and prognosis in patients with gastric cancer.METHODS This study included 200 patients with gastric adenocarcinoma,and conducted an in-depth analysis of their baseline characteristics,relationship between tumor markers and staging,and prognosis.The study found that CA19-9 has a signi-ficant correlation with tumor stage,the average levels of CA24-2,CEA,CA72-4 and ferritin were slightly increased disregarding the stage of tumor.Survival analysis showed that increases in CEA,CA19-9,CA24-2,and ferritin were all associated with shortened overall survival of patients.Further multivariate ana-lysis revealed that elevated serum CA72-4 levels were an inde-pendent adverse prognostic factor.RESULTS This study reveals that there is a significant correlation between the expression levels of serum tumor markers CEA,CA19-9,CA72-4,CA24-2 and ferritin in patients with gastric cancer and prognosis,and can be used as important indicators for prognostic evaluation of gastric cancer.In particular,markers that appear abnormally elevated initially may help identify gastric cancer patients with poor prognosis.CONCLUSION Serum CEA and CA19-9 play an important role in the prognosis assessment of gastric cancer,and are effective tools to guide clinical practice and optimize individualized treatment strategies for gastric cancer patients.

血清高迁移率族蛋白 B1和糖类抗原72-4在早期胃癌患者检测中的价值

目的：探讨血清高迁移率族蛋白B1（HMGB1）和糖类抗原72-4（CA72-4）在早期胃癌患者检测中的价值。方法50例早期胃癌患者作为胃癌组，45例胃部良性病变患者作为胃部良性病变组，100例健康查体者作为健康组，测定并比较入选人群血清HMGB1和CA72-4。结果早期胃癌组血清HMGB1和CA72-4阳性率高于胃部良性病变组和健康体检组（χ^2＝33．69、82．95、51．41、104．74，均P＜0．01），而胃部良性病变组的阳性率与健康体检组的差异无统计学意义（χ^2＝3．80、1．90，均P＞0．05）。 HMGB1诊断早期胃癌敏感度为70．0％，特异度为95．2％，准确度为88．7％；CA72-4诊断早期胃癌的敏感度为80．0％（40／50），特异度为97．2％（141／145），准确度为92．8％（181／195）。联合检测时，诊断早期胃癌的敏感度为94．0％（47／50），而特异度为93．1％（135／145），准确度为93．3％（182／195），高于单项检测的敏感度与准确度。有淋巴结转移的早期胃癌患者血清HMGB1和CA72-4均明显高于无淋巴结转移的患者（ t＝2．927、4．096，均P ＜0．05）。结论联合检测血清HMGB1和CA72-4可以早期诊断胃癌，并对患者预后进行判断。
