Avaliação da resposta inflamatória como marcador de atividade tumoral em pacientes com câncer colorretal

Abstract

Biological markers have been studied in order to identify factors that would be able to predict evolution of patients with colorectal cancer that could help to select high risk relapse groups. However, none of them has been recommended for clinical use. The objective of this work was to verify the correlation between the inflammatory response and tumor activity in patients with colorectal carcinoma. An observational and descriptive study was performed. Blood samples from 28 patients were collected postoperatively for determination of C-reactive protein (CRP) and Interleukin-10 (IL-10). The analysis was performed comparatively according to curative and non curative resection. The correlation levels of CPR and carcinoembryonic antigen (CEA) in the curative resection group was lower compared with non curative resection group (p< 0.05). No difference between the groups was observed in the levels of IL-10. This study suggests that high levels of CRP, but not IL-10 reflect tumor activity.
