Applicative Value of Serum CA19-9, CEA,CA125 and CA242 in Diagnosis and Prognosis for Patients with Pancreatic Cancer Treated by Concurrent Chemoradiotherapy

Objective: To evaluate the application value of serum CA19-9, CEA, CA125 and CA242 in diagnosis andprognosis of pancreatic cancer cases treated with concurrent chemotherapy. Materials and Methods: 52patients with pancreatic cancer, 40 with benign pancreatic diseases and 40 healthy people were selected. Theelectrochemiluminescence immunoassay method was used for detecting levels of CA19-9, CEA and CA125, anda CanAg CA242 enzyme linked immunoassay kit for assessing the level of CA242. The Kaplan-Meier methodwas used for analyzing the prognostic factors of patients with pancreatic cancer. The Cox proportional hazardmodel was applied for analyzing the hazard ratio (HR) and 95% confidential interval (CI) for survival timeof patients with pancreatic cancer. Results: The levels of serum CA19-9, CEA, CA125 and CA242 in patientswith pancreatic cancer were significantly higher than those in patients with benign pancreatic diseases andhealthy people (P<0.001). The sensitivity of CA19-9 was the highest among these, followed by CA242, CA125and CEA. The specificity of CA242 is the highest, followed by CA125, CEA and CA19-9. The sensitivity andspecificity of joint detection of serum CA19-9, CEA, CA125and CA242 were 90.4% and 93.8%, obviouslyhigher than single detection of those markers in diagnosis of pancreatic cancer. The median survival time of52 patients with pancreatic cancer was 10 months (95% CI7.389~12.611).. Patients with the increasing level ofserum CA19-9, CEA, CA125, CA242 had shorter survival times (P=0.047. 0.043, 0.0041, 0.029). COX regressionanalysis showed that CA19-9 was an independent prognostic factor for patients with pancreatic cancer (P=0.001,95%CI 2.591~38.243). Conclusions: The detection of serum tumor markers (CA19.9, CEA, CA125 and CA242)is conducive to the early diagnosis of pancreatic cancer and joint detection of tumor markers helps improve thediagnostic efficiency. Moreover, CA19-9 is an independent prognostic factor for patients with pancreatic cancer.     

术前CEA、CA19-9和CA50的表达水平与结直肠癌临床病理特点的相关性研究--附1 340例病例分析

目的分析手术前血清CEA、CA19-9和CA50在结直肠癌患者中的表达情况,研究其在不同肿瘤临床分期中的表达差异,及其与临床病理学特点的相关性。方法回顾分析2000年1月~2004年9月于肿瘤医院接受治疗的结直肠肿瘤病例1340例,术前采用放射免疫法测定血清CEA、CA19-9和CA50水平,术后综合术前影像学检查、术中探查结果和术后组织病理学检测进行临床分期,应用SPSS12.0统计软件进行相关性分析。结果在1340例患者中,有59例为外院手术后复发或者转移的患者,另外的1281例患者均为初治病例。其中结直肠癌患者1327例。CEA、CA19-9和CA50检测阳性率分别为25.9%、22.3%和22.8%,同手术性质(根治性/姑息性)和脉管侵犯等临床病理指标相关。CEA、CA19-9和CA50在不同肿瘤分期中表达差异显著,主要在D期患者和复发转移患者中出现高阳性率。CEA在粘液腺癌和腺癌组织中表达差异显著。三个指标的表达和患者性别无关。结论CEA、CA19-9及CA50和肿瘤的临床分期密切相关,其阳性表达提示合并淋巴结或者脏器转移可能,是预后不良指标。

A clinical evaluation of carbohydrate antigen 19-9 and carcinoembryonic antigen in patients with pancreatic carcinoma

We have studied serum carbohydrate antigen 19-9 (CA 19-9) and carcinoembryonic antigen (CEA) in 221 persons to assess their usefulness in the diagnosis of pancreatic carcinoma. Although serum CA 19-9 and CEA in all healthy controls were within normal limits, the positive ratings of serum CA 19-9 and CEA in all benign disease were 9.8% and 18.1%, respectively. Sensitivity of serum CA 19-9 for pancreatic carcinoma was 70.5%, which was higher than that found in healthy controls, benign disease, and other malignant disease except biliary carcinoma; but sensitivity of serum CEA levels (67.7%) was not different from that seen in malignant disease. Three of 34 patients (8.8%) with pancreatic carcinoma who had a above-normal levels of serum CA 19-9 but not serum CEA were resectable. Although there was no correlation between serum CA 19-9 and CEA, advanced stages of pancreatic, gastric, and colorectal carcinoma tend to show high serum CA 19-9 and CEA, but no statistical differences were observed in relation to the stages of these carcinomas. Comparative studies of serum CA 19-9 and CEA for sensitivity and the predictive value of true positive and negative results for detecting pancreatic, gastric, and colorectal carcinoma showed that serum CA 19-9 has significantly higher sensitivity and predictive value of true positive results for pancreatic carcinoma than for gastric and colorectal carcinoma (P less than 0.05). However, serum CEA measurements did not show any difference between these carcinomas, and the highest predictive value of a true negative result for excluding pancreatic carcinoma was also observed in serum CA 19-9. These results indicate that although the CA 19-9 assay is not specific for pancreatic carcinoma, it is more useful adjunct method for diagnosing pancreatic carcinoma, possibly in resectable stages.     

Carcinoembryonic antigen, CA 19-9, and CA 125 in normal and carcinomatous human colorectal tissue

In 115 primary colorectal carcinomas and 64 normal colorectal mucosa specimens the concentrations of carcinoembryonic antigen (CEA), CA 19-9, and CA 125 were measured. The determinations were performed in cytosols by use of radioimmunometric and enzymeimmunometric assays and related to the wet tissue weight. In the cancer tissue the CEA levels ranged from 5.5 to 1990 micrograms/g tissue and were significantly higher (P less than 0.0001) than those found in the normal mucosa (1.2-58.6 micrograms/g). The CA 19-9 content in carcinoma specimens (120-72660 U/g) was also significantly higher (P = 0.011) than in the normal mucosa (37-5800 U/g). In contrast, no significant difference of the CA 125 concentrations between the normal and the cancer tissue was found. The relative operating characteristic (ROC) curves for the three markers corroborate CEA as the marker superior to CA 19-9. On the other hand is shown that CA 125 is completely unable to discriminate between normal and cancer tissues. A decreasing CEA tissue concentration and an increasing dedifferentiation of colorectal cancers were significantly (P = 0.018) related with each other. Higher tumor stages implied significantly higher tissue marker values of CA 19-9 (P = 0.027) and CA 125 (P = 0.0008). The findings correspond quite well with serum examinations of the three markers which have been reported earlier.
