ABSTRACT
ABSTRACT

Background:

The role of ascitic and serum levels of various tumour biomarkers in the discrimination of cause of ascites is not well established.

Objective:

To evaluate the role of serum and ascitic levels of tumor biomarkers (CA 72-4, CA 19-9, CEA and CA 125) in discrimination of cause of ascites.

Methods:

A prospective study was conducted in consecutive patients presenting with ascites. Serum and ascitic levels of CA 19-9, CA 125, CA 72-4 and carcinoembryonic antigen (CEA) were determined at the presentation. The patients with cirrhotic ascites, tuberculous peritonitis (TBP) and peritoneal carcinomatosis (PC) were eventually included in analysis.

Results:

Of the 93 patients (58 males, mean age 47 years) included, the underlying cause was cirrhosis in 31, PC in 42 and peritoneal tuberculosis in 20. The best cutoff for discriminating benign and malignant ascites for serum CEA, CA 19-9 and CA 72-4 were 6.7 ng/mL, 108 IU/mL and 8.9 IU/mL, respectively. The best cutoff for discriminating benign and malignant ascites for ascitic CA 125, CEA, CA 19-9 and CA 72-4 were 623 IU/mL, 8.7 ng/mL, 33.2 IU/mL and 7 IU/mL, respectively.

Conclusion:

The performance of single biomarker for the prediction of underlying PC is low but a combination of serum CA 19-9 and CA 72-4 best predicted the presence of peritoneal carcinomatosis.
RESUMO
RESUMO

Contexto:

O papel dos níveis ascíticos e séricos de vários biomarcadores de tumores na discriminação da causa das ascites não está bem estabelecido.

Objetivo:

Avaliar o papel dos níveis séricos e ascíticos de biomarcadores tumorais (CA 72-4, CA 19-9, CEA e CA 125) na discriminação da causa das ascites.

Métodos:

Estudo prospectivo foi realizado em pacientes consecutivos que apresentaram ascite. Foram determinados níveis do soro e ascítico de CA 19-9, CA 125, CA 72-4 e antígeno carcinoembrínico (CEA). Os pacientes com ascites cirróticas, peritonite tuberculosa e carcinomatose peritoneal (CP) foram eventualmente incluídos na análise.

Resultados:

Dos 93 pacientes (58 homens, média de idade 47 anos) incluídos, a causa básica foi cirrose em 31, CP em 42 e tuberculose peritoneal em 20. O melhor corte para discriminação de ascites benignas e malignas para soro CEA, CA 19-9 e CA 72-4 foram 6,7 ng/mL, 108 UI/mL e 8,9 UI/mL, respectivamente. O melhor corte para discriminação de ascites benignas e malignas para CA 125 ascitico, CEA, CA 19-9 e CA 72-4 foram 623 UI/mL, 8,7 ng/mL, 33,2 UI/mL e 7 UI/mL, respectivamente.

Conclusão:

O desempenho do biomarcador único para a previsão do CP subjacente é baixo, mas uma combinação de soro CA 19-9 e CA 72-4 melhor previu a presença de carcinomatose peritoneal.
