The concomitant determination of different tumor markers in patients with epithelial ovarian cancer and benign ovarian masses: relevance for differential diagnosis.

The serum levels of CA 125 (cutoff limit, 65 U/ml), CA19.9 (cutoff, 40 U/ml), CA 15.3 (cutoff, 32 U/ml), CA72.4 (cutoff, 3.8 U/ml), and TATI (cutoff, 22 ng/ml) were preoperatively measured in 90 patients with epithelial ovarian cancer and in 254 patients with benign ovarian pathology. CA125 had a sensitivity of 75.6%, a specificity of 86.6%, and a diagnostic accuracy of 83.7% for epithelial ovarian cancer; CA19.9 had a sensitivity of 35.6%, a specificity of 81.1%, and a diagnostic accuracy of 69.2%; CA15.3 had a sensitivity of 57.1%, a specificity of 93.9%, and a diagnostic accuracy of 84.6%; CA72.4 had a sensitivity of 70.7%, a specificity of 91.8%, and a diagnostic accuracy of 86.2%; and TATI had a sensitivity of 47.3%, a specificity of 95.3%, and a diagnostic accuracy of 82.9%. CA 125 was the most sensitive marker for nonmucinous tumors, while CA19.9 and CA72.4 were the antigens more frequently expressed by mucinous malignancies. The sensitivities of serum CA 125 (81.1% vs 50.0%; P = 0.01) and TATI (55.2% vs 18.8%; P = 0.02) were higher in patients above 50 years of age than in younger patients while specificities were quite similar in both age groups. The association of serum CA125 and CA19.9 had a significantly higher sensitivity (93.2% vs 81.1%; P = 0.03) and a slightly lowered specificity (78.9% vs 86.0%; P = 0.46) than CA125 assay alone in the differential diagnosis of ovarian masses in patients above 50 years of age.

Intracystic evaluation of tumor markers in benign and malignant ovarian pathology

OBJECTIVE: To evaluate, in patients with benign and malignant ovarian cysts, serum samples and ovarian intracystic fluids for the presence of tumor markers such as CA 125, CA 15.3, tissue polypeptide antigen (TPA), CA 19.9 and the carcinoembryonic antigen (CEA). MATERIAL AND METHOD: We studied overall 64 patients with ovarian pathology. Sixteen patients were affected by functional cysts, 28 women by benign cystic tumors and 20 by cystoadenocarcinomas. RESULTS: Average serum levels of all but CA 15.3, TPA and CEA tumor markers of benign cystic ovarian tumors were higher than those of functional cysts. All but CA 19.9 mean intracystic fluid markers levels were more elevated in benign tumors than in functional cysts. In patients with malignant cystic tumors, all but CEA mean serum marker levels were higher than those of benign tumors; furthermore even all mean intracystic levels of markers were more elevated than those of benign tumors. CONCLUSION: This study confirmed the high positivity of tumor markers such as CA 125, CA 15.3, TPA, CA 19.9 and CEA in both the serum and intracystic fluid of patients with malignant epithelial ovarian tumors.     

Monitoring endometrial adenocarcinoma with a four tumor marker combination. CA 125, squamous cell carcinoma antigen, CA 19.9 and CA 15.3.

The combined value of four tumor markers, in the follow-up of endometrial adenocarcinoma, is analyzed. Cancer antigen 125 (CA 125), squamous cell carcinoma antigen (SCC), carbohydrate antigen 19.9 (CA 19.9) and carbohydrate antigen 15.3 (CA 15.3) were used in 213 evaluations from 105 patients. Sensitivity as regards recurrence or progression of disease was 45% (CA 125), 9% (SCC), 51% (CA 19.9) and 21% (CA 15.3). Specificities as regards the 'no evidence of disease' ranged from 95% to 99%. Single tumor marker efficiency ranged from 90% for CA 125 to 84% for SCC (p = 0.08). With the two tumor marker combination sensitivity increased up to 77% achieved with CA 125-CA 19.9, but efficiency increased only slightly (92.0% for CA 125-SCC). In the best three tumor marker combination, a sensitivity of 85% was achieved (CA 125-CA 19.9-CA 15.3), and an efficiency of 92.2%. The simultaneous use of the four tumor markers did not improve assay results. The possibility of recurrence or progression of disease in some combinations was very low (4.6% when CA 125 and CA 19.9 negative, 3% when CA 125, CA 19.9 and CA 15.3 negative), a fact to be considered in order to avoid aggressive management in such cases. The tumor markers were of limited value for the prediction of recurrences. The suggestion of recurrence when the increase in tumor markers was the only finding was confirmed in only 7%, while confirmation was made in 100% when there was another pathological finding.     

CA125 in ovarian cancer: European Group on Tumor Markers guidelines for clinical use

CA125 is currently the most widely used tumor marker for ovarian epithelial cancer. The aim of this article is to provide guidelines for the routine clinical use of CA125 in patients with ovarian cancer. Due to lack of sensitivity for stage I disease and lack of specificity, CA125 is of little value in the detection of early ovarian cancer. At present, therefore, CA125, either alone or in combination with other modalities, cannot be recommended for screening for ovarian cancer in asymptomatic women outside the context of a randomized controlled trial. Preoperative levels in postmenopausal women, however, may aid the differentiation of benign and malignant pelvic masses. Serial levels during chemotherapy for ovarian cancer are useful for assessing response to treatment. Although serial monitoring following initial chemotherapy can lead to the early detection of recurrent disease, the clinical value of this lead-time is unclear. CA125 is the ovarian cancer marker against which new markers for this malignancy should be judged.     

Combining CA 125 and SMR serum markers for diagnosis and early detection of ovarian carcinoma

OBJECTIVES: The serum tumor marker CA 125 is elevated in most clinically advanced ovarian carcinomas. Because these elevations may precede clinical detection by a year or more, CA 125 is potentially useful for early detection as part of an ovarian cancer screening program. However, CA 125 is often not elevated in clinically detected cancer and is frequently elevated in women with benign ovarian tumors. CA 125 may be more useful in conjunction with one or more other tumor biomarkers. Additional markers could play a role if, when used with CA 125, they identify some carcinomas missed by CA 125 (i.e., they improve sensitivity), rule out false positives (i.e., improve specificity), or are able to detect the same cancers earlier. METHODS: We have evaluated a composite marker (CM) that combines CA 125 and a previously described soluble mesothelin related (SMR) marker in sera from 52 ovarian cancer cases, 43 controls with benign ovarian tumors, and 220 normal risk controls who participated in a screening program, including 25 healthy women having two serum samples collected 1 year apart. CA 125, SMR, and CM were evaluated for their ability to identify clinical disease and for their temporal stability, which assesses their ability to obtain even greater sensitivity when used in a longitudinal screening program. RESULTS: CM has the best sensitivity, with specificity equal to CA 125. Importantly, CM has temporal stability at least as high as CA 125. CONCLUSION: The CM may outperform CA 125 alone in a longitudinal screening program as well as in a diagnostic setting.     

LPA、CA125与经阴道彩色多普勒超声联合诊断卵巢上皮癌的临床价值

目的:探讨血浆溶血磷脂酸(LPA)在卵巢上皮癌患者血浆中的表达水平,及其与血清CA125和经阴道彩色多普勒超声(TV-CDUS)联合应用诊断卵巢上皮癌的临床价值。方法:术前检测卵巢上皮癌48例,卵巢良性肿瘤30例的LPA、CA125,以20例健康者作为对照,卵巢肿瘤患者同时经阴道超声评分和TV-CDUS检查。结果:卵巢癌患者LPA水平明显高于卵巢良性肿瘤组和健康对照组,差异有统计学意义(P0.05),LPA水平在良性肿瘤组与健康对照组之间无显著差异(P0.05)。单独应用LPA、CA125、TV-CDUS检测诊断卵巢癌的敏感性和特异性分别为87.5%、79.16%、81.25%和80%、70%、86%,各组间敏感性和特异性比较,无显著差异(P0.05)。LPA、CA125、TV-CDUS 3项联合检测诊断卵巢癌的敏感性和特异性为95.80%和94%,与单独应用CA125检测特异性比较,差异有统计学意义(P0.05)。LPA诊断卵巢癌的敏感性和特异性与卵巢癌分期和病理类型无关(P0.05),CA125诊断卵巢癌的敏感性和特异性与卵巢癌的分期和病理类型有关(P0.05)。结论:卵巢上皮癌患者血浆LPA水平明显升高,有望成为卵巢上皮癌诊断的敏感指标,联合检测血浆LPA、血清CA125与TV-CDUS有助于术前卵巢癌的诊断。     

The concomitant determination of different serum tumor markers in epithelial ovarian cancer: relevance for monitoring the response to chemotherapy and follow-up of patients.

The levels of CA125, CA19.9, CA15.3 CA72.4, and TATI were serially measured during and after chemotherapy in 43 patients with epithelial ovarian cancer having elevated concentrations of one or more of the antigens before initial surgery. The value of 35 U/ml was chosen as cutoff level of CA125 for the monitoring of disease. Changes in the serum levels of CA125, CA19.9, CA15.3, CA72.4, and TATI correlated with the clinical course of disease in 87.4% of 215, 76.3% of 80, 71.3% of 122, 76.0% of 167, and 48.5% of 101 instances, respectively. After the sixth course of monthly primary chemotherapy, elevated antigen levels were strong predictors of persistent disease, while normal antigen values were associated with both positive and negative second-look findings. It is worth noting that antigen levels above the cut-off limits before the third course, but still in the normal range after the sixth course, seemed to be predictive of positive second-look findings. Among patients with elevated antigen levels at diagnosis, clinical detection of neoplastic progression after treatment was stopped was preceded by an elevation of serum CA125 in 93.3% of 15 patients, of serum CA19.9 in 80.0% of 5 patients, of serum CA15.3 in 66.7% of 9 patients, of serum CA72.4 in 81.8% of 11 patients, and of serum TATI in 40% of 10 patients. In patients with positive CA125 assay at diagnosis, the concomitant evaluation of the other antigens did not seem to be of additional benefit for monitoring epithelial ovarian cancer. However, the measurement of the other tumor markers could represent an interesting biochemical tool for the management of patients with negative CA125 assay. In particular the evaluation of serum CA19.9 or CA72.4 could be very useful in the monitoring of patients with mucinous ovarian cancer, which often fails to express CA125 antigen.     

Diagnostic usefulness of stepwise discriminant analysis employing the values of CA125, TPA, IAP, CEA and ferritin in sera measured simultaneously for gynecological malignant neoplasms

The values for CA125, TPA, IAP, CEA, and ferritin in sera were measured simultaneously in 68 healthy nonpregnant females and 133 patients with various gynecological diseases, and examined by stepwise discriminant analysis. The usefulness and the limits for diagnosis of various gynecological diseases were investigated for each tumor marker. Also, the diagnostic usefulness of stepwise discriminant analysis employing the values for five tumor markers in sera was studied for gynecological malignancies compared with that of measuring serum CA125 alone. Because the mean values for CA125 in sera were increased specifically in the ovarian cancer patient group compared with those of other tumor markers in sera, the measurement of serum CA125 was considered to be more useful in diagnosing ovarian cancer than that of the other tumor markers. The mean values for CA125 in sera, however, were also increased more significantly in the groups of patients with endometriosis and normal pregnancies than in the group of healthy nonpregnant females (p less than 0.005). In the stepwise discriminant analysis employing the values for CA125 and four other tumor markers in sera, the diagnostic usefulness of each tumor marker was demonstrated in the early diagnosis, the differential diagnosis, and the determination of complete remission after several therapies for ovarian cancers.     

Significance of CA 125 serum level in discrimination between benign and malignant masses in the pelvis

Aim Our aim was to confirm that preoperative CA 125 serum level can be useful for discrimination between benign and malignant masses in the pelvis.Methods Preoperative CA 125 serum level was analyzed retrospectively in 121 patients who had surgery because of a malignant ovarian tumor and in 91 patients with benign masses in the pelvis. The cutoff serum level CA 125 between benign and malignant masses in the pelvis was 35 and 65 IU/ml.Results Of those patients with a malignant ovarian tumor, 65.3% had menopause whereas only 31.5% of those with a benign tumor did so. The average age of the patients with a malignant tumor was 54.2 years and of those with a benign tumor 46.8 years. The preoperative CA 125 serum level was higher than 35 IU/ml in 80.2% and higher than 65 IU/ml in 72.7% of all analyzed patients with a malignant tumor, whereas it was 23.9% and 9.8% respectively in patients with a benign mass. In early stage ovarian cancer disease (borderline stage, I/II) the preoperative CA 125 serum level was higher than 35 IU/ml in 67.8% and in 52.5% higher than 65 IU/ml. In advanced stages (III/IV), it was higher than 35 and 65 IU/ml in 96.1%. After therapy the CA 125 serum level dropped below 35 IU/ml in 70.8% and after three chemotherapy courses in 78.1%. A CA 125 level less than 35 IU/ml was achieved by therapy in 84.2% patients with an early stage disease (I/II) and in 62.1% in advanced stages (III/IV). The calculated sensitivity was 80.2% and negative 74.5% (CA 125 higher than 35 IU/ml) and 72.7%, 90.2%, 90.7%, 71.6% respectively (CA 125 higher than 65 IU/ml).Conclusion Preoperative determination of CA 125 is a very useful method to discriminate between benign and malignant masses in the pelvis.
