Abstract
Serum glycoproteins at malignant tumors was investigated by measurement of glycoprotein, double diffusion with cancer tissues and immunofluorescence methode, it was as follow as:
In comparision with normal serum glycoprotein at patients with various advanced cancer was clearly increased, but at patients with early cancer, it was not always increased.
Relationship between grade of cancer invasion with gastric cancer and serum glycoproteins was recognized a difinite.
By immunofluorescence methode, glycoproteins was find in cancer cell membrane.
In malignant tumors, glycoproteins was increased more α1-fraction by electrophoresis of serum of patients with cancer and cancer tissues.
