[Microheterogeneity of two acute phase proteins in patients with ovarian carcinoma]

Concentrations of two acute phase proteins: alpha 2-macroglobulin (alpha 2M) and transferrin (Tf) as well as glycosylation profiles of alpha 2M and Tf were studied in sera samples from 13 patients suffering from ovarian cancer. In the observed group of patients with ovarian cancer in whom the progression of disease was noticed low concentrations of both investigated proteins were present. On the contrary, the microheterogeneity of both alpha 2M and Tf was changed towards variants of both proteins more weakly reacting with ConA, what was previously described for AGP and ACT in all chronic inflammatory conditions including cancer.
