Northover 13 reported that the risk of recurrent disease within two years of primary surgery was more than double in those whose serum CEA was raised preoperatively. We observed, as in previous studies, that Malignancies, prothrombotic mutations, and the risk of venous thrombosis.

antígeno carcinoembrionario – English translation – Spanish-English dictionary

Value of carcinoembryonic antigen in the management of colorectal cancer. All had operable cancer. Plasma CEA in the post-surgical monitoring of colorectal carcinoma. Services on Demand Journal. Sin embargo, constituyen un reflejo de la actividad de la enfermedad y del crecimiento tumoral.

The sensitivity was lower than in the studies of Wang 9 and Tate 10 but similar to McCall Tumor markers are molecules usually glycoproteinsthe levels of which may be elevated in the presence of a cancer, either as a host’s reaction to the tumor or as a product of the tumor itself.

The results from this series are consistent with several published works. En el tercer grupo, esto es, el de los MT de baja especificidad se incluyen los MT con una sensibilidad dependiente del estadio, pero cuya especificidad es baja, incluso en las fases avanzadas de la enfermedad. Eur J Intern Med. MT de especificidad y sensibilidad variable. As in the majority of previous studies 2,4we also did not observed any differences of CEA levels when comparing sex, age, tumor site, tumor diameter or histological differentiation.

Marcadores tumorales en el tumor de primario desconocido. An audit of tumour marker requests in Northern Ireland.


CEA levels were elevated in 7 of the 12 patients who developed liver metastases. Staging and prognosis by CEA Test. In the group of patients with elevated preoperative CEA and recurrence, this occurred in the first year of follow up. The sensitivity, specificity, the positive predictive value and the negative predictive value are described in Table 5.

Reappraisal of preoperative carcinoembryonic antigen levels as a prognostic factor in resectable colorectal cancer. The value of serum carcinoembryonic antigen in predicting recurrent disease following curative resection of colorectal cancer. Although the tumor stage is today the most valuable prognostic variable in colorectal cancer, the preoperative CEA value can provide some additional information in the prognosis of the patient. Although the information provided by the tumor stage is still the most valuable prognostic variable today, the preoperative elevated CEA level provides additional information on the prospects for survival, suggesting a more aggressive tumor and probably identifying a subgroup of patients for adjuvant therapy.

Aspectos generales de los marcadores tumorales. The relationship between high CEA serum levels in the preoperative period and worse prognosis has been investigated in several studies 2,3,4,5so far without definite conclusion. The differences in serum CEA were statistically significant. We calculated the sensitivity, specificity and positive and negative predictive value for CEA as an index of tumor recurrence. Medifam revista en la Internet. Thus, markers with high levels of sensitivity and specificity would allow for the detection of patients with cancer, and for their differentiation from healthy individuals or from patients with benign pathologies.

Si las cifras del marcador sufren un incremento continuo, se puede afirmar con bastante seguridad que el origen es tumoral. Guidelines for the use of tumour markers. We can say that, in general, due to the lack of high diagnostic sensitivity and specificity, tumor markers are not helpful for an early detection of neoplasms, but they do help to confirm a diagnosis already established by more sensitive methods.


The use of prognostic markers in surgery for colorectal cancer. National Cancer Institute Consultado Ene El hallazgo de concentraciones elevadas de cualquier marcador, de forma aislada, tiene un valor limitado. In Brazil, it is the 4th largest cause of cancer in women and the 6th in men. Unidad de Medicina Paliativa.

East Afr Med J. However, their true clinical value lies in patient monitoring, both for detecting early recurrence and for evaluating the effectiveness of the established treatment. Role of tumor markers in patients with solid tumors: The mean serum levels were higher for tumors in Dukes stage C than for stages B or A.

The aim of this study was to retrospectively evaluate the serum CEA levels before surgery in operable colorectal cancer patients as a predictor of recurrence. Role of alpha-fetoprotein in the diagnosis and management of hepatocellular carcinoma.

Carcinoemnriogenico percentage was higher in the patients with nodal involvement Dukes C. The possible relationships between serum levels of CEA and sex, age, diameters of the tumor, histological diffentiation, tumor site colon or rectum and Dukes stage have also been evaluated. Our aim is to review the tumor markers most commonly used in our clinical practice, as well as some agreed recommendations on the indication of their determination in various tumors.
