[Neopterin].

Abstract

Putzki H, Aschern F, Henkel E, Heymann H. Neopterin: a tumor marker in colorectal carcinoma? Dis Colon Rectum 1987;30:879-883. Neopterin is compared with other tumor markers in colorectal carcinoma. Its sensitivity is clearly lower than that of CEA, TPA and CA 19/9 and is even lower than the sensitivity of the erythrocyte sedimentation rate. The ability of neopterin to discriminate between different tumor stages is also lower than that o[ the other markers. The discriminant analysis shows that measurement o[ neopterin in the serum of patients with colorectal carcinoma gives no essential additional information. [
