Combining prognostic value of serum carbohydrate antigen 19-9 and tumor size reduction ratio in pancreatic ductal adenocarcinoma

BACKGROUND Pancreatic ductal adenocarcinoma(PDAC)is a common cancer with increasing morbidity and mortality due to changes of social environment.AIM To evaluate the significance of serum carbohydrate antigen 19-9(CA19-9)and tumor size changes pre-and post-neoadjuvant therapy(NAT).METHODS This retrospective study was conducted at the Chongqing Key Laboratory of Translational Research for Cancer Metastasis and Individualized Treatment,Chongqing University Cancer Hospital.This study specifically assessed CA19-9 levels and tumor size before and after NAT.RESULTS A total of 156 patients who completed NAT and subsequently underwent tumor resection were included in this study.The average age was 65.4±10.6 years and 72(46.2%)patients were female.Before survival analysis,we defined the post-NAT serum CA19-9 level/pre-NAT serum CA19-9 level as the CA19-9 ratio(CR).The patients were divided into three groups:CR<0.5,CR>0.5 and<1 and CR>1.With regard to tumor size measured by both computed tomography and magnetic resonance imaging,we defined the post-NAT tumor size/pre-NAT tumor size as the tumor size ratio(TR).The patients were then divided into three groups:TR<0.5,TR>0.5 and<1 and TR>1.Based on these groups divided according to CR and TR,we performed both overall survival(OS)and disease-free survival(DFS)analyses.Log-rank tests showed that both OS and DFS were significantly different among the groups according to CR and TR(P<0.05).CR and TR after NAT were associated with increased odds of achieving a complete or near-complete pathologic response.Moreover,CR(hazard ratio:1.721,95%CI:1.373-3.762;P=0.006),and TR(hazard ratio:1.435,95%CI:1.275-4.363;P=0.014)were identified as independent factors associated with OS.CONCLUSION This study demonstrated that post-NAT serum CA19-9 level/pre-NAT serum CA19-9 level and post-NAT tumor size/pre-NAT tumor size were independent factors associated with OS in patients with PDAC who received NAT and subsequent surgical resection.

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.

Carbohydrate antigen 19-9 — tumor marker: Past, present, andfuture

Carbohydrate antigen 19-9 (CA 19-9) is a cell surface glycoprotein complex mostcommonly associated with pancreatic ductal adenocarcinoma (PDAC). Koprowskifirst described it in 1979 using a mouse monoclonal antibody in a colorectalcarcinoma cell line. Historically, it is one of the most commonly used tumormarkers for diagnosing, managing, and prognosticating PDAC. Additionally,elevated CA 19-9 levels are used as an indication for surgery in suspected benignpancreatic conditions. Another common application of CA 19-9 in the biliary tractincludes its use as an adjunct in diagnosing cholangiocarcinoma. However, itsclinical value is not limited to the hepatopancreatobiliary system. The reality isthat the advancing literature has broadened the clinical value of CA 19-9. Thepotential value of CA 19-9 in patients' workup extends its reach to gastrointestinalcancers – such as colorectal and oesophageal cancer – and further beyond thegastrointestinal tract - including urological, gynecological, pulmonary, andthyroid pathologies. Apart from its role in investigations, CA 19-9 presents apotential therapeutic target in PDAC and acute pancreatitis. In a bid toconsolidate its broad utility, we appraised and reviewed the biomarker’s currentutility and limitations in investigations and management, while discussing thepotential applications for CA 19-9 in the works for the future.

Detection of pancreatic cancer with normal carbohydrate antigen 19-9 using protein chip technology

AIM: To develop a method to differentiate pancreatic cancer patients from healthy or benign individuals when carbohydrate antigen (CA) 19-9 is normal.

Preoperative serum carbohydrate antigen 19-9 levels predict early recurrence after the resection of early-stage pancreatic ductal adenocarcinoma

BACKGROUND Pancreatic ductal adenocarcinoma(PDAC)is a serious disease with a poor prognosis.Only a minority of patients undergo surgery due to the advanced stage of the disease,and patients with early-stage disease,who are expected to have a better prognosis,often experience recurrence.Thus,it is important to identify the risk factors for early recurrence and to develop an adequate treatment plan.AIM To evaluate the predictive factors associated with the early recurrence of earlystage PDAC.METHODS This study enrolled 407 patients with stage I PDAC undergoing upfront surgical resection between January 2000 and April 2016.Early recurrence was defined as a diagnosis of recurrence within 6 mo of surgery.The optimal cutoff values were determined by receiver operating characteristic(ROC)analyses.Univariate and multivariate analyses were performed to identify the risk factors for early recurrence.RESULTS Of the 407 patients,98 patients(24.1%)experienced early disease recurrence:26(26.5%)local and 72(73.5%)distant sites.In total,253(62.2%)patients received adjuvant chemotherapy.On ROC curve analysis,the optimal cutoff values for early recurrence were 70 U/mL and 2.85 cm for carbohydrate antigen 19-9(CA 19-9)levels and tumor size,respectively.Of the 181 patients with CA 19-9 level>70 U/mL,59(32.6%)had early recurrence,compared to 39(17.4%)of 226 patients with CA 19-9 level≤70 U/mL(P<0.001).Multivariate analysis revealed that CA 19-9 level>70 U/mL(P=0.006),tumor size>2.85 cm(P=0.004),poor differentiation(P=0.008),and non-adjuvant chemotherapy(P=0.025)were significant risk factors for early recurrence in early-stage PDAC.CONCLUSION Elevated CA 19-9 level(cutoff value>70 U/mL)can be a reliable predictive factor for early recurrence in early-stage PDAC.As adjuvant chemotherapy can prevent early recurrence,it should be recommended for patients susceptible to early recurrence.

Carbohydrate antigen 19-9 as a novel prognostic biomarker in distal cholangiocarcinoma

BACKGROUND Distal cholangiocarcinoma(DCC)presents as one of the relatively rare malignant tumors in the digestive system and has a poor long-term prognosis.Curative resection is currently the most appropriate therapy for patients with DCC because of the lack of effective adjuvant therapies.Therefore,it is important to accurately predict the prognosis for formulating a reasonable treatment plan and avoiding unnecessary surgical trauma.AIM To minimize the interference of obstructive jaundice on carbohydrate antigen 19-9(CA19-9)level by adapting CA19-9 toγ-glutamyltransferase(GGT)as an indicator,to determine the strong associations between CA19-9/GGT and postoperative neoplasm recurrence and long-term outcome of DCC.METHODS We enrolled 186 patients who were diagnosed with DCC between January 2010 and December 2019 and performed radical excision with strict criteria as follows in our hospital.Receiver operating characteristic curves were drawn according to preoperative CA19-9/GGT and 1-year survival.Based on this,patients were divided into two groups(group 1,low-ratio,n=81;group 2,high-ratio,n=105).Afterwards,by the way of univariate and multivariate analysis,the risk factors influencing postoperative tumor recrudesce and long-term prognosis of patients with DCC were screened out.RESULTS Optimum cut-off value of CA19-9/GGT was 0.12.Patients in group 2 represented higher CA19-9 and lymphatic metastasis rate accompanied by lower GGT,when compared with group 1(P<0.05).The 1-,3-and 5-year overall survival rates of patients in groups 1 and 2 were 88.3%,59.2%and 48.1%,and 61.0%,13.6%and 13.6%,respectively(P=0.000).Multivariate analysis indicated that CA19-9/GGT,lymphatic metastasis and tumor differentiation were independent risk factors for tumor recurrence and long-term prognosis of DCC.CONCLUSION Elevation of CA19-9/GGT performed better as a biomarker of aggressive carcinoma and predictor of poor clinical outcomes by reducing the effect of obstruction of biliary tract on CA19-9 concentration in patients with DCC.

Prognostic significance of SUVmax and serum carbohydrate antigen 19-9 in pancreatic cancer

Clinical characteristics and outcomes in carbohydrate antigen 19-9 negative pancreatic cancer

BACKGROUND Pancreatic ductal adenocarcinoma(PDAC)is a leading cause of death from cancer worldwide.Tumor markers like carbohydrate antigen 19-9(CA 19-9)have been proven valuable as a diagnostic tool and a predictor for tumor staging and response to therapy.AIM To delineate the phenotype of normal CA 19-9 PDAC according to clinical features,disease staging and prognosis as compared with high CA 19-9 PDAC cases.METHODS We performed a retrospective single-center analysis of all PDAC cases admitted in our Gastroenterology department over a period of 30 mo that were diagnosed by endoscopic ultrasound-guided tissue acquisition.Patients were divided into two groups according to CA 19-9 levels over a threshold of 37 U/mL.We performed a comparison between the two groups with regard to demographic and clinical data,biomarkers,tumor staging and 6-mo survival.RESULTS Altogether 111 patients were recruited with 29 having documented normal CA 19-9(<37 U/mL).In the CA 19-9 negative group of patients,20.68%had elevated levels of both CEA and CA 125,13.79%for CA 125 only whilst 17.24%for CEA only.The two groups had similar demographic characteristics.Abdominal pain was more frequently reported in positive vs negative CA 19-9 PDAC cases(76.83%vs 55.17%),while smoking was slightly more prevalent in the latter group(28.04%vs 31.03%).Tumors over 2 cm were more frequently seen in the positive CA 19-9 group,reflecting a higher proportion of locally advanced and metastatic neoplasia(87.7%vs 79.3%).Sixmonth survival was higher for the negative CA 19-9 group(58.62%vs 47.56%).CONCLUSION Elevated CA 19-9 at diagnosis seems to be associated with a more pronounced symptomatology,high tumor burden and poor prognosis compared to negative CA 19-9 PDAC cases.CEA and CA 125 can be adjunctive useful markers for PDAC,especially in CA 19-9 negative cases.

Neutrophil-to-lymphocyte ratio and carbohydrate antigen 19-9 as prognostic markers for advanced pancreatic cancer patients receiving first-line chemotherapy

BACKGROUND A decline in serum carbohydrate antigen 19-9(CA19-9)levels during systemic chemotherapy is considered as a prognostic marker for patients with advanced pancreatic cancer.Neutrophil-to-lymphocyte ratio(NLR)has been extensively studied as a simple and useful indicator of prognosis in various cancers including pancreatic cancer.AIM To assess the prognostic significance of NLR and CA19-9 in patients with advanced pancreatic adenocarcinoma received first-line chemotherapy according to CA19-9 positivity.METHODS We retrospectively analyzed patients diagnosed with advanced pancreatic cancer who received first-line chemotherapy between January 2010 and July 2017 at the Catholic University of Seoul St.Mary’s Hospital.Patients were divided according to CA19-9 positivity(CA19-9-positive vs-negative groups)and pre-and posttreatment NLR levels.To determine cut-off value of NLR and CA19-9 reduction,time-dependent receiver operating characteristic curve was applied.We evaluated overall survival(OS)and progression-free survival(PFS)for each group using Kaplan-Meier method,and we performed multivariate analyses on the entire cohort.RESULTS We included 271 patients in this study.Cut-off value of NLR and CA19-9 reduction was determined as 2.62 and 18%.Multivariate analysis showed that post-treatment NLR<2.62 and reduction of≥18%of baseline CA19-9 were significantly associated with OS and PFS.Post-treatment NLR≥2.62 showed hazard ratio(HR)of 2.47[95%confidence interval(CI):1.84-3.32,P<0.001]and CA19-9 decline(≥18%)showed HR of 0.51(95%CI:0.39-0.67,P<0.001)for OS.When CA19-9-positive patients were divided into groups according to CA19-9 response(responder vs non-responder)and post-treatment NLR(<2.62 vs≥2.62),CA19-9 responder and post-treatment NLR<2.62 group showed better survival than CA19-9 non-responder and post-treatment NLR≥2.62 group(OS 11.0 mo vs 3.9 mo,P<0.001;PFS 6.3 mo vs 2.0 mo,P<0.001).The combination of CA19-9 decline and post-treatment NLR showed a significant correlation with clinical response in CA 19-9 positive group.Within the CA19-9-negative group,the posttreatment NLR<2.62 group showed better survival than the post-treatment NLR≥2.62 group(OS 12.7 mo vs 7.7 mo,P<0.001;PFS 6.7 mo vs 2.1 mo,P<0.001),and post-treatment NLR showed correlation with clinical response.CONCLUSION In advanced pancreatic cancer patients positive for CA19-9 and treated with systemic chemotherapy,the combination of post-treatment NLR<2.62 and 18%decline of CA19-9 at the first response evaluation is a good prognostic marker.Post-treatment NLR<2.62 alone could be used as a prognostic marker and an adjunctive tool for response evaluation in CA19-9-negative patients.

Ciliated hepatic foregut cyst with high intra-cystic carbohydrate antigen 19-9 level

A ciliated hepatic foregut cyst (CHFC) is a rare foregut developmental malformation usually diagnosed in adulthood. Five percent of reported cases of CHFC transform into squamous cell carcinoma. We report the presentation, evaluation, and surgical management of a symptomatic 45-year-old male found to have a 6.2 cm CHFC. Contrast tomography-guided fine-needle aspiration demonstrated columnar, ciliated epithelium consistent with the histologic diagnosis of CHFC. The intracystic levels of carbohydrate antigen (CA) 19-9 and carcinoembryonic antigen (CEA) were extremely high (978118 U/mL and 973 &#x003bc;g/L, respectively). Histologically, the wall of the cyst showed characteristic pseudopapillae lined with a ciliated stratified columnar epithelium, underlying smooth muscle, an outer fibrous layer and no atypia. Immunohistochemistry for CA19-9 and CEA was positive. This is the first case report of a CHFC in which levels of CA 19-9 and CEA were measured. Our findings suggest that a large sized multilocular cyst and elevated cyst CA19-9 and CEA levels do not exclude a CHFC from consideration in the diagnosis. CHFCs should be included in the differential diagnosis of hepatic lesions. Accurate diagnosis of a CHFC is necessary given its potential for malignant transformation, and surgical excision is recommended.

High level of preoperative carbohydrate antigen 19-9 is a poor survival predictor in gastric cancer

AIM:To assess the clinical significance and the prognostic value of preoperative serum carbohydrate antigen 19-9(CA 19-9)level in gastric cancer.METHODS:Between January 2005 and December2006,1960 patients underwent surgery for histologically confirmed gastric cancer.Of these,163 patients had elevated serum levels of CA 19-9 preoperatively,and1628 patients had normal serum levels of CA 19-9 preoperatively.For this study,325 patients were selected from the group of 1628 patients by age,sex,and cancer stage to serve as controls.Statistically significant differences in survival rates were calculated using the log-rank test.A P value less than 0.05 was considered statistically significant and was determined using SAS software.RESULTS:The baseline characteristics showed some differences between the two groups with regard to histology.Overall survival(OS)in the elevated and nonelevated group was 37.90 and 68.67 mo,respectively(P<0.001).N stage(P=0.001)was a significant predictor of disease-free survival by multivariate analysis.Also,N stage(P<0.001),and the presence of peritoneal metastasis(P<0.001)remained independent factors in predicting OS by multivariate analysis.Additionally,preoperative serum CA 19-9 levels were significantly associated with OS in univariate(P=0.009)and multivariate(P=0.021)analyses.CONCLUSION:Serum CA 19-9 can be considered an independent prognostic factor in predicting OS in patients anticipating surgery for gastric cancer.

Endoscopic ultrasonography in patients with elevated carbohydrate antigen 19-9 of obscure origin

AIM:To evaluate the efficacy of endoscopic ultrasonography(EUS) in patients with elevated carbohydrate antigen(CA) 19-9 levels of obscure origin.METHODS:Patients who had visited Pusan National University Hospital because of elevated serum CA 19-9 levels,between January 2007 and December 2009,were retrospectively enrolled.EUS had been performed on all subjects,in addition to routine blood tests,endoscopy,abdominal computed tomography(CT) and other clinical exams,which had not revealed any abnormal findings suggestive of the origin of the elevated CA 19-9 levels.RESULTS:Of the 17 patients,gallbladder sludge was detected in 16 patients(94.1%) and common bile duct sludge was observed in 3 patients(17.6%).After the administration of ursodeoxycholic acid to 12 of the patients with gallbladder sludge,CA 19-9 levels normalized in 6 of the patients after a median of 4.5 mo.CONCLUSION:EUS is a useful diagnostic method for patients with elevated CA 19-9 levels of obscure origin,even if the reason for abnormal levels of this serum marker cannot be determined through prior examinations,including abdominal CT.

The combined detection of carcinoembryonic antigen,carcinogenic antigen 125,and carcinogenic antigen 19-9 in colorectal cancer patients

BACKGROUND Hepatic metastases are common and difficult to treat after colorectal cancer(CRC)surgery.The predictive value of carcinoembryonic antigen(CEA),cancer antigen(CA)125 and CA19-9 combined tests for liver metastasis is unclear.AIM To evaluate predictive value of combined tests for CEA,CA125,and CA19-9 levels in patients with liver metastases of CRC.METHODS The retrospective study included patients with CRC alone(50 cases)and patients with CRC combined with liver metastases(50 cases)who were hospitalized between January 2021 and January 2023.Serum CEA,CA125 and CA19-9 levels were compared between the two groups,and binary logistic regression was used to analyze the predictive value of the combination of these tumor markers in liver metastasis.In addition,we performed receiver operating characteristic(ROC)curve analysis to assess its diagnostic accuracy.RESULTS The results showed that the serum CEA,CA125 and CA19-9 levels in the CRC with liver metastasis group were significantly higher than those in the CRC alone group.Specifically,the average serum CEA level in the CRC with liver metastasis group was 162.03±810.01 ng/mL,while that in the CRC alone group was 5.71±9.76 ng/mL;the average serum CA125 levels were 43.47±83.52 U/mL respectively.and 13.5±19.68 U/mL;the average serum CA19-9 levels were 184.46±473.13 U/mL and 26.55±43.96 U/mL respectively.In addition,binary logistic regression analysis showed that CA125 was significant in predicting CRC liver metastasis(P<0.05).ROC curve analysis results showed that the areas under the ROC curves of CEA,CA125 and CA19-9 were 0.607,0.692 and 0.586.CONCLUSION These results suggest that combined detection of these tumor markers may help early detection and intervention of CRC liver metastasis,thereby improving patient prognosis.

构建癌胚抗原、糖类抗原19-9生存模型公式预测结直肠癌患者生存时间

目的构建术前癌胚抗原(CEA)、糖类抗原19-9(CA19-9)模型,预测结直肠癌(CRC)患者的生存时间。方法收集江门市中心医院就诊的313例CRC患者,利用Beckman Access化学发光免疫分析仪检测CRC患者术前血清CEA、CA19-9水平,运用χ^(2)检验评估其与CRC患者临床病理参数的关系,Kaplan-Meier生存分析和Cox多因素分析分别评估CRC患者生存及预后。结果CEA、CA19-9均与CRC患者pT、pN、pM分期,临床Ⅰ、Ⅱ、Ⅲ、Ⅳ分期,进展,复发,脉管浸润,转移部位等因素相关(P<0.05)。CEA升高患者的总生存时间(OS)较CEA正常患者缩短(76.85个月vs 110.83个月,P=0.000)。CA19-9升高患者的OS也有相同趋势(P=0.000)。Cox多因素分析发现CEA、CA19-9是预测CRC患者生存的独立因素(HR分别为2.190和2.874;95%CI分别为1.486~3.225和1.947~4.242;P均<0.05)。联合CEA、CA19-9构建模型公式,赋予CEA正常为0分,CEA升高为1分,CA19-9正常为0分,CA19-9升高为1分,并设CC值=CEA评分+CA19-9评分,结果发现CC值最高患者的OS最短,CC值最低患者的OS最长(P<0.05)。结论构建的CEA、CA19-9模型公式可以有效地预测CRC患者预后。

目的分析细胞角蛋白19片段(CYFRA21-1)、蛋白激酶B(PKB)和糖类抗原19-9(CA19-9)水平联合超声内镜检查术(EUS)对胃肠道间质瘤和非胃肠道间质瘤的鉴别价值。方法前瞻性纳入2020年1月-2023年7月该院收治的69例胃肠道间质瘤患者作为研究组,另择同期78例非胃肠道间质瘤患者(胃肠道平滑肌瘤25例,胃肠道神经鞘瘤53例)作为对照组。比较两组患者一般资料、EUS指标和肿瘤标志物,绘制受试者操作特征曲线(ROC curve),分析血清CYFRA21-1、PKB和CA19-9水平单独检测,以及联合EUS,对胃肠道间质瘤的诊断价值。结果与对照组比较,研究组灰度平均值、灰度标准偏差、血清CYFRA21-1、PKB和CA19-9水平更高(P<0.05)。不同性别和年龄的胃肠道间质瘤患者,灰度平均值、灰度标准偏差、血清CYFRA21-1、PKB和CA19-9水平比较,差异均无统计学意义(P>0.05)。与肿瘤直径≤5 cm、病理性核分裂象≤5个/50 HPF的胃肠道间质瘤患者比较,肿瘤直径>5 cm、病理性核分裂象>5个/50 HPF的胃肠道间质瘤患者,灰度平均值、灰度标准偏差、血清CYFRA21-1、PKB和CA19-9水平更高(P<0.05)。将胃肠道间质瘤纳入阳性,非胃肠道间质瘤纳入阴性,ROC curve显示,联合检测胃肠道间质瘤的诊断价值高于EUS、血清CYFRA21-1、PKB和CA19-9水平单独检测,曲线下面积(AUC)为0.936,敏感度为82.61%,特异度为91.03%。结论在胃肠道间质瘤中,CYFRA21-1、PKB、CA19-9水平、灰度平均值和灰度标准偏差升高,CYFRA21-1、PKB和CA19-9水平联合EUS在胃肠道间质瘤中诊断价值较高。

CT联合MMP-2、MMP-9、CA19-9对早期结直肠癌T分期的预测价值

目的:探讨CT联合血清金属基质蛋白酶2(MMP-2)、金属基质蛋白酶9(MMP-9)、糖类抗原19-9(CA19-9)检测对结直肠癌患者T分期的预测价值。方法:选取结直肠癌患者110例,行CT联合血清MMP-2、MMP-9、CA19-9检测。结果:CT诊断结直肠癌T_(1~2)期、T_(3)期、T_(4)期符合率分别为79.17%(38/48)、84.62%(33/39)、86.96%(20/23),总诊断符合率为82.73%(91/110)。T_(1~2)期、T_(3)期及T_(4)期结直肠癌患者血清MMP-2、MMP-9、CA19-9水平比较差异均有统计学意义(均P<0.05);T_(3)期患者血清MMP-2、MMP-9、CA19-9水平均明显高于T_(1~2)期(均P<0.05);T_(4)期患者血清MMP-2、MMP-9、CA19-9水平均明显高于T_(3)期及T_(1~2)期(均P<0.05)。Spearman相关性分析显示,血清MMP-2、MMP-9、CA19-9水平与结直肠癌T分期呈显著正相关(均P<0.05)。ROC曲线显示,CT联合MMP-2、MMP-9、CA19-9(联合诊断模型)鉴别诊断结直肠癌T_(1~2)期与T_(3)期的AUC明显高于各单项指标(均P<0.05);联合诊断模型鉴别诊断结直肠癌T_(3)期与T_(4)期的AUC明显高于各单项指标(均P<0.05)。结论:CT联合MMP-2、MMP-9、CA19-9检测鉴别诊断结直肠癌T分期具有较高的应用价值。
