[Abstract]Objective:To study the diagnostic value of combined detection of CA724,CEA,CA242 and CA199 tumor markers in gastric cancer.Methods:30 cases of gastric cancer patients in our hospital from April 2017 to April 2018 were selected as the observation group,and 30 patients with benign gastric lesions in our hospital were selected as the control group at the same time.At the same time,30 cases of healthy persons in our hospital were selected as the reference group,and the serum of three groups of subjects were collected,and R was collected.The ELECSY 2010 fully automated electroluminescent instrument produced by oche is selected,and CA724,CEA,CA242 and CA199 matching kit are selected for laboratory testing.Results:the four indexes of patients with benign gastric lesions in the control group were not statistically significant compared with those in the reference group,P > 0.05.The four indexes of the gastric cancer patients in the observation group were significantly higher than those in the control group,and the difference was statistically significant between the groups,P < 0.05;the detection rate of the four indexes was significant.The positive rate of gastric cancer in stage I,II and III was significantly higher than that of single test.The difference was significant between the groups,P < 0.05,but there was no statistical difference between the positive rate of gastric cancer stage IV and P > 0.05.Conclusion:the four tumor markers of serum CA724,CEA,CA242 and CA199 were combined in the diagnosis of gastric cancer,and the positive rate was high,which could provide a favorable basis for clinical diagnosis.

胃癌是一种发生与胃黏膜上皮的恶性肿瘤,发病率位于恶性肿瘤首位[1],多好发于50岁以上中老年患者[2],男女比约为2:1,早期无明显症状,或者出现嗳气、上腹部不适等非特异性症状,与胃炎、胃溃疡等疾病的临床表现症状较为相似,早期诊断率较低[3]。胃癌早期诊断及时治疗对于患者预后效果的提高具有重要意义,随着临床诊断技术水平的提升,胃癌早期诊断方法与效果均得到有效的推广利用的,但是诊断效果仍需商榷[4]。因此,本组研究选取我院收治的60例胃部病变患者与30例健康体检者作为研究对象,选取CA724、CEA、CA199、CA242肿瘤标志物联合诊断的诊断价值价值进行研究,现报告如下。

1 资料与方法

1.1 一般资料

选取2017年4月至2018年4月来我院行手术治疗的30例胃癌患者作为观察组,均经术后石蜡病例切片确诊为胃癌,其中男性18例,女性12例,年龄区间在20~78岁,平均年龄为(53.28±4.26)岁,胃癌分期:Ⅰ期6例,Ⅱ期14例,Ⅲ期8例,Ⅳ期2例;并选取同期我院收治的胃部良性病变患者30例作为对照组,其中男性19例,女性11例,年龄区间在23~76岁,平均年龄为(54.56±4.81)岁,同时选取同期来我院行健康体检者的30例患者作为参照组,其中男性16例,女性14例,年龄区间在21~79岁,平均年龄为(55.08±4.61)岁,所有纳入对象均在知情同意下自愿参与研究,并经过我院伦理委员会同意后开始本次研究,三组纳入对象的临床资料比较无统计学意义,P>0.05。

1.2 方法

收集三组纳入对象的清晨空腹静脉血3mL,将采集的血样标本放置于EP试管内,进行离心处理,离心速度为3000r/min,离心时间为10min,经离心后收集三组血清,采用Roche公司生产的ELECSY 2010全自动电化学发光仪,并选取仪器配套的CA724、CEA、CA242以及CA199配套试剂进行实验室检测。

1.3 参数范围

CA724正常参考范围为0~6U/mL;CEA正常参考范围为0~5U/mL;CA242正常参考范围为0~12U/mL;CA199正常参考范围为0~39U/mL。

1.4 统计学分析

本组数据均采用SPSS19.0软件进行组间数据比较,计数资料以(n,%)进行描述且行卡方检验,计量资料以(x±s)描述且行t检验,若组间数据P<0.05则具备统计学意义。

3 讨论

据流行病学调查提示,胃癌发病存在明显的地域性,西北及东部沿海地区的发病率相对较高[5],由于饮食结构改变、工作压力增大等原因,胃癌也呈年轻化趋势发展[6]。根据临床实践发现[7],胃癌细胞易产生多种物质,在胃液以及其他组织中被检测出来的物质称为胃癌标志物。CEA多见于胚胎胃肠黏膜上皮细胞、恶性肿瘤细胞外[8];CA199属于高分子量糖蛋白的一种,多种腺癌患者血清CA199水平明显升高[9];CA242属于黏蛋白、在正常胰腺与结肠黏膜中存在,表达情况较低[10];CA724属于类黏蛋白分子,具有较高分子量[11]。

本次研究中观察胃癌组患者的CA724(29.51±0.71)U/mgL、CEA(9.08±0.69)U/mgL、CA242(34.45±0.91)U/mg、CA199(89.41±5.71)U/mg明显高于对照组,组间差异显著P<0.05,而对照组胃部良性病变患者与参照组健康人群的CA724、CEA、CA242与CA199水平比较无统计学意义,P>0.05;据本次研究提示,胃癌患者血清CA724、CEA、CA242与CA199水平明显高于正常健康人群以及胃部良性病变患者。结果显示,胃癌患者应用四项指标联合诊断的阳性检出率为100%明显高于其他指标的单项检测结果,组间比较差异显著P<0.05;根据四项指标有利于判断胃癌的发生及发展,且相比于单独指标检测,四项指标的阳性检出率更高,且肿瘤标志物的表达与肿瘤临床分期有关,胃癌晚期肿瘤标志物阳性检出率越高。

因此,胃癌患者应用血清CA724、CEA、CA242与CA199肿瘤标志物进行联合诊断,阳性检出率较高,可为临床诊断提供有利依据。
