Specificity of fibrinopeptide A (FpA) as a marker for gastrointestinal cancers before and after surgery.
In 70 patients affected by gastrointestinal malignancies the plasma fibrinopeptide A (FpA) levels were assessed both before and at various intervals after the operation. At the same time other more commonly used tests of coagulation were carried out. In all the patients plasma FpA levels were shown to be variously elevated, so that they could give useful clues to the diagnosis, treatment, prognosis and follow-up of the gastrointestinal malignancies. In all the patients the coagulation tests fell into the normal ranges. However in the patients affected by recto-sigmoid adenocarcinoma an increase of circulating fibrin degradation products (FDPs) was observed which paralleled the increase of plasma FpA. In conclusion, in gastrointestinal malignancies the increase of plasma FpA levels suggests the cancer-induced start of the coagulation cascade. The assay of this peptide proves to be a reliable marker for these diseases.
