血清CA153、CA125和CEA联合检测在乳腺癌诊断中的应用

Objective To study the clinical singificance of serum tumor markers (CA153, CA125 and CEA) in doagnosis of breast cancer. Methods Electrochemiluminescence immunoassay (ECLIA) was used to analyze serum levels of CA153,CA125 and CEA in 55 patients with breast canc-er (breast cancer group),20 patients with benign breast lesions (benign breast lesion group) and 20 healthy controls (healthy control group). Results The levels of CA153, CA125 and CEA in breast cancer group were significantly higher than those in healthy control group (P<0.05); the levels of CEA and CA153 in breast cancer group were significantly higher than those in benign breast lesion group (P<0.05);the level of CA153 in postoperative patients was statistically lower than that in pre-operative patients (P<0.05);the levels of CEA and CA153 in breast cancer patients with stage Ⅲ and Ⅳ were significantly higher than those in healthy controls (P<0.05); the level of CA153 with stage Ⅲ and Ⅳ was higher than that in ones with stage Ⅰ and Ⅱ. The combined dection of CA153, CA125 and CEA in breast cancer patients increased the experimental sensitivity to 53.8% and specific-ity to 83.3%. Conclusion Detections of CA153,CA125 and CEA contribute to diagnosis of breast cancer. CA153 and CEA are of clinical practical value in differential diagnosis of benign and malignant breast tumor,monitoring of course of breast cancer.     

67例肺癌ECT全身骨显像及血清Cyfra21-1、NSE、CEA、CA125联合测定分析

Objective To explore the correlation between Cyfra21-1、 NSE、 CEA、CA125 and the bone metastasis in lung cancer.Methods Images were obtained on a gamma camera (E.CAM,Siemens,Erlangen,Germany)using 99mTC-MDP as a skeletal imaging agent.67 cases diagnosed as lung cancer were performed by ECT bone imaging,serum concentration of Cyfra21-1,NSE,CEA and CA125 were measured among 30 healthy individual,33 patients with pulmonary tuberculosis and 67 patients with lung cancer by electrogenerated chemiluminescence(ECL) (Roche,Germany).Results The serum Cyfra21-1、NSE、CEA、CA125 from lung cancer were higher than that of controls group and pulmonary tuberculosis group(P<0.01).and the pleural Cyfra21-l and NSE were significantly higher than that in serum.In lung cancer,there are correlation between tumor marker and its pathological types.Cyfra21-1 concentration in squamous cell carcinoma were significantly higher than that of other lung cancers(P<0.01),NSE level in small cell lung cancer were significantly higher than that other lung cancers(P<0.01).33 patients with lung cancer had no obvious sign of bone metastases among 67 cases (accounting for 49.3%),34 patients had bone metastases with varying degrees(accounting for 50.7 % ) ;Adenocarcinoma has highest incidence of bone metastasis( 64 % ),followed by small cell lung cancer and squamous cell carcinoma.Cyfra21-land NSE level is highest in cases with wide spread bone metastasis,followed by those with part bone metastasis and without bone metastasis in turn.Conclusion There are relationship between tumor marker and bone metastasis of lung cancer.Multiple bone metastases often were accompanied by obvious change of serum tumor marker.Cyfra21-lis a useful tool in diagnosis of non-small cell lung cancer,especially in squamous cell carcinoma.NSE is useful to identify the small cell lung cancer.Combined determination of Cyfra21-1,NSE,CEA and CA125 can improve sensitivity,accuracy and positive rate of diagnosis lung cancer.It seems that the whole body bone imaging combined Cyfra21-1,NSE,CEA and CA125 detection have important clinical value in diagnosis and identification of lung cancer.

Objective To explore the clinical values of combined detection of serum CA125, CA72-4 and HE4 levels in the early diagnosis of ovarian cancer. Methods The serum levels of CA125, CA72-4 and HE4 in 111 patients with ovarian cancer, 130 patients with benign ovarian disease and 90 healthy female controls were measured by electrochemical luminescence immunoassay (ECLIA) and enzyme-linked immunosorbent assay (ELISA) methods. The diagnostic values of the three markers were analyzed separately and combinedly in ovarian cancer. Results The serum levels of CA125, CA72-4 and HE4 of ovarian cancer patients were significantly higher than those of benign ovarian disease patients and healthy controls(Ps ＜ 0. 01). The positive expression rate of HE4(63.5%) in patients with stage Ⅰ ovarian cancer was significantly higher than that of CA125(55. 8%) and CA72-4 (42. 6%)(Ps ＜ 0. 05) . The combined detection of the three markers may improve the overall accuracy of the early diagnosis of ovarian cancer to 75.8%. The diagnostic sensitivity of serum CA125 was relatively higher in serous cystadenocarcinoma, endometrioid carcinoma and poorly differentiated adenocarcinoma; the diagnostic sensitivity of serum CA72-4 was relatively higher in mucinous cystadenocarcinoma and endometrioid carcinoma; the diagnostic sensitivity of serum HE4 was relatively higher in serous cystadenocarcinoma and endometrioid carcinoma. Conclusion CA125 can serve as the first choice of tumor maker in the diagnosis of ovarian cancer, and the combined detection of serum levels of CA125, CA72-4 and HE4 may increase the diagnostic sensitivity of stage Ⅰ ovarian cancer.

Abstract：

Objective To assess the association between serum levels of carbohydrate antigen 125 (CA125) and the heart function in the elderly with congestive heart failure (CHF). Methods CA125, carcinoembryonic antigen (CEA) ,alpha-fetoprotein ( AFP), CA199, CA15-3, CA724, liver and kidney function and NT-proBNP were measured in 178 patients with heart failure. Ve, Va, Ve/Va, left ventricular end-diastolic diamete ( LVEDD), left ventricular end-systolic diamete ( LVESD ), left ventricular ejection fraction ( LVEF ) and time were measured using echocardiograph. All patients were classified as Ⅰ + Ⅱ , Ⅲ and Ⅳ level according to the criteria of New York Heart Assocation ( NYHA), and the incidence of pleural effusion, peripheral edema,atrial fibrillation were observed. Results Among the 178 patients,serum CA125 were ≤35 U/ml in 91 patients with median of 9.9( 3.4 - 33.7 ) U/ml, ＞ 35 U/ml in 87 patients with median of 64. 4 ( 20. 2 - 462. 1 ) U/ml.Among those patients with CA125 ＞ 35 U/ml ,heart function was classified as level Ⅲ + Ⅳ in 82 patients,and level Ⅰ + Ⅱ in 5 patients. Among the patients with CA125 ≤35 U/ml,heart function was classified as level Ⅲ + Ⅳin 7 patients,and level Ⅰ + Ⅱ in 84 patients. Heart function was significantly different between the two CA125 groups( x2= 133. 3 ,P ＜0. 001 ). The incidence of pleural effusion,atrial fibrillation ,peripheral edema in the higher CA125 group were 32. 2%, 51.7% and 78. 2%, respectively, which were significantly higher than those in the normal CA 125 group ( 5.5 %, 9. 9% and 19. 8 %, repactively ) ( P ＜ 0. 01 ). NT-proBNP, LVESD,LVEF and time in the higher CA125 group were 2524. 0( 104.0 - 19 308. 0) ng/L,35 (27 -55) mm,49% (23%-66% ) and 268 (210 -312)ms, which were significantly differenct from those in the normal CA125 group [356.0 ( 32.0 - 5201.0) ng/L, 32 ( 26 - 53 ) mm, 59% ( 42% - 69% ) and 290 ( 260 - 340 ) ms, respectively](Ps ＜0. 05). The linear regression showed that serum CA125 was positively correlated with NT-ProBNP and urea nitrogen ( BUN ) ( r= 0. 3326 and 0. 3430, Ps= 0. 002 ) , as well as negtively correlated with LVEF and time (r= -0. 3016,P =0. 006;r = -0. 336,P =0. 004).
