R-157. Serum CEA, CA-125, CA-15.3 and CA-19.9 levels as a diagnostic test for endometriosis

Immunoassays of the tumor markers CA 19.9, CA125 and CA 15.3 are generally acknowledged to be a useful tool in the management of cancer patients. As a consequence, many methods developed by different companies are now commercially available. However, discrepancies have been described in the results of marker determinations even when the same monoclonal antibody was used. An external quality assessment (EQA) was carried out; starting from 1989 about 110 laboratories participated; since December 1991 the program was linked with the interlaboratory program Oncocheck organized by the Service de Radiopharmacie et Radioanalyse, University of Lyon. At present more than 200 laboratories of many European countries are involved: cumulatively 47 quality control samples have been prepared and sent to the participants. This manuscript is a report on data collected for CA 19.9, CA 125, and CA 15.3.

Purpose Although serum tumor markers (STMs) are widely used in clinical practice, their predictive role for the response to anticancer treatment is still controversial. The correlation of CEA, CA 15.3, CA 19.9, CA 125 (only with peritoneal involvement) and NSE levels with imaging response and clinical benefit was investigated in 60 non-selected patients with metastatic epithelial cancers treated by single-agent docetaxel chemotherapy. Methods STM measurement was performed at baseline and subsequently every three to four weeks. We applied the WHO criteria to evaluate both STM and instrumental responses. Concordance analysis was performed by the Cohen Kw index, and the significance of the results was established using the Fleiss, Cohen & Everitt test. Qualitative interpretation of data was obtained with the Landis & Koch scale. Correlations of STM response with clinical benefit (PS or pain improvement) were evaluated by the chi-square test. Results The primary tumors included breast cancers (38 patients), gastrointestinal non-colorectal cancers (12 patients), and lung cancers (10 patients). An overall significant good degree of agreement was observed between STM and instrumental response (p<0.0005). The degree of agreement for each marker was as follows: excellent for CEA (p<0.0005) and CA 125 (p=0.006), good for CA 15.3 (p<0.0005) and CA 19.9 (p=0.011). Restricted analysis for the correlation of each marker with primary tumor origin showed good prediction of radiological response for CA 15.3 and CEA in breast cancer patients (p<0.0005 for both), for CEA and CA 19.9 in gastrointestinal cancer patients (p=0.01 and 0.04, respectively), and for CEA+NSE in lung cancer patients (p=0.01). Conversely, STM response did not correlate significantly with the clinical benefit for the patients, both in terms of PS and pain improvement (p=0.24 and p=0.42, respectively). Conclusion This study showed STMs to be good predictors of tumor response. Although STMs cannot replace diagnostic imaging, in metastatic cancer they might be useful to optimize the timing of radiological re-evaluation in the palliative setting.

Marcadores Tumorales

Muchos marcadores tumorales (MT) no son específicos a un tipo particular de cáncer y el nivel de uno de ellos puede aumentar como consecuencia de más de un tipo de cáncer, por lo que se utilizan en combinación para lograr mayor efectividad diagnóstica. Este trabajo se propone evaluar el valor diagnóstico de la combinación de nueve MT utilizados en diagnóstico de neoplasia tanto de forma individual como combinados. Se realizó un estudio retrospectivo entre enero 2013 y mayo de 2015 en el Laboratorio Clínico del Centro de Investigaciones Médico Quirúrgicas de La Habana a 100 pacientes con diagnóstico de cáncer o sospecha clínica de neoplasia oculta a quienes se les determinaron los marcadores tumorales: antígeno carbohidrato (CA) 19.9, CA 72.4, CA 125, CA 15.3, antígeno carcinoembrionario (CEA), componente de la citoqueratina 19 (Cyfra 21-1), gonadotropina coriónica (HCG), ferritina y antígeno prostático de superficie (PSA). En todos los MT se observó un incremento del valor de corte sobre el valor límite superior de referencia mayor al 8%. En conjunto, la sensibilidad, especificidad, valor predictivo positivo (VPP) y valor predictivo negativo fueron de 23%, 99%, 96% y 51%, respectivamente. Para un valor de corte de 50 la especificidad y el VPP aumentaron a 99,6% y 97,5%, respectivamente. El uso de los 9 marcadores tumorales en conjunto mostró ser útil en el proceso de diagnóstico de pacientes con enfermedad neoplásica. Palabras clave: marcadores tumorales, CA 19.9, CA 72.4, CA 125, CA 15.3, CEA, Cyfra 21-1, HCG, Ferritina y PSA Abstract: Many tumor markers are not specific to a particular type of cancer and the level of one of them may increase as a result of more than one type of cancer, that’s why they are used in combination to achieve greater diagnostic effectiveness.

An increase of cutoff value above the upper limit reference value in all higher TM 8% was observed. Overall, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value were 23 %, 99 %, 96 % and 51 %, respectively. For a cut value of 50 specificity and PPV, they increased to 99.6% and 97.5%, respectively. The use of 9 tumor markers together showed to be useful in the process of diagnosing patients with neoplastic disease.

Forty-nine healthy subjects (Group I), 24 patients with benign lung diseases (Group II) and 48 patients surgically treated for lung cancer (Group III): 28 with squamous cell carcinoma (SCC) and 20 with adenocarcinoma (adenoca), were tested for the presence of carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA), cancer antigen CA 125 and antigen CA 15.3. The four markers were measured in the serum of the patients of the three groups and in the cytosol extract of tumoral and peritumoral tissues of Group III subjects. The mean levels of serum CEA and TPA were significantly higher in squamous cell carcinoma and in adenocarcinoma patients than in normal subjects. In benign lung disease serum CEA was equal and TPA slightly higher than in normal subjects. CA 125 was higher in the serum of patients with malignant diseases compared to normal or benign lung diseases but this difference was not statistically significant. Serum CA 15.3 levels were similar in all subjects studied. CA 125 in squamous cell carcinoma cytosol was much higher than in peritumoral cytosol whereas the other three markers were not significantly different in tumor cytosol or peritumoral cytosol. A direct correlation between serum and cytosol values was observed for CEA, but not for the other markers. The levels of the four markers in serum and cytosol did not correlate with the stage or grade of the tumors.
