RESUMEN
Objective To observe the application effect of the risk of ovarian malignancy algorithm(ROMA)in screening ovarian cancer among high risk population.Methods The human epididymis protein 4(HE4)and carbohydrate antigen 125 (CA125 )were detected in 1 753 cases of high risk for overian cancer,56 cases of ovarian cancer(positive control)and 60 healthy people,patients. Then the ROMA value was calculated in combination with the subject′s menstruation status.The detection results were analyzed and compared among groups.The high risk group for ovarian cancer devided according to the ROMA value was further performed the confirmatory test and the low risk group was monitored by follow up.The detection rates of ovarian cancer were compared be-tween the two subgroups.Results In the high risk population,the diagnostic performance of the ROMA value for ovarian cancer was superior to that of the single HE4 or CA125;the ROMA value had statistically significant difference between the high risk sub-group in the high-risk population with ovarian cancer or the healthy control group(P <0.05);in 1 753 cases of high risk popula-tion,37 cases were included in the high risk subgroup,in which 3 cases of ovarian cancer were screened out and in clinical early stage.The detection rate of ovarian cancer in the high risk subgroup was 8.1%.No case of ovarian cancer was detected out in the low risk subgroup.Conclusion The ROMA value is conducive to early screening for ovarian cancer in the high risk population, which can save the medical cost and increase the detection rate.
RESUMEN
Objective To investigate the clinical value of tissue polypeptide specific antigen(TPS),neuron-specific enolase(NSE),carcinoembryonie antigen(CEA)and CA125 in serum of small cell lung cancer(SCLC)patients and its significance in diagnosis and disease monitoring.Methods Serum leveh of TPS was detected using ELISA and serum levels of NSE,CA125 and CEA was detected using ECLin 27 1 SCLC patients.80 pulmonary benign disease patients and 224 normal healthy people.Diagnostic values of these tumor markers were analyzed by receiver operative characteristic(ROC)curve.Results The levels of TPS,NSE,CA125 and CEA iu the serum of SCLC group were signifieanfly higher than those in pulmonary benign disease and healthy group(Z＞1.90,P＜0.01).The levels of TPS and NSE in the serum of extensive stage small cell lung cancer(ESCLC)patients were significantly higher than those in limited stage small cell lung cancer(LSCLC)(Z=2.69,2.27,P=0.009,0.02 respectively).,The level of TPS and NSE showed statistical significance among SCLC patients with different prognosis after therapy(Z=4.06,3.11.P=0.001,0.007 respectively).The TPS+NSE showed the highest sensitivity of 86.7%,and the specificity,PPV and NPV were 75.0%,81.0% and 82.2%,respectively.Conclusions Serum levels of TPS,NSE,CA125 and CEA are useful for SCLC diagnosis.TPS+NSE shows the highest clinical values in SCLC diagnosis and prognosis.
