A Ceruloplasmina Como Enzima Marcadora de Atividade Neoplásica Maligna

Hyperceruloplasminemia was detected in U strain isogenic male rats bearing a syngeneic sarcoma in all phases of neoplasm evolution. Normal levels of ceruloplasmin oxidase activity were only observed after lhe first dose of intraperitoneally administered cyclophosphamide (100 mg/kg). However subseque...

Description
Summary:Hyperceruloplasminemia was detected in U strain isogenic male rats bearing a syngeneic sarcoma in all phases of neoplasm evolution. Normal levels of ceruloplasmin oxidase activity were only observed after lhe first dose of intraperitoneally administered cyclophosphamide (100 mg/kg). However subsequent weekly therapy with the drug did not prevent the return of high levels of sérum ceruloplasmin in the tumor hosts. Healthy rats treated similarly with cyclophosphamide presented a fall in the enzyme activity after the first dose. The constant hyperceruloplasminemia observed suggests the presence of viable latent sarcoma celles and can serve as a biochemical test to monitorize the malignant process.
