[The erythrocyte functional status and phospholipid composition in breast cancer patients].

A study of the osmotic resistance of both red blood cells and phospholipids of whole blood and isolated red blood cells showed breast cancer with symptoms of metastasis to involve perverted influence of calcium ions on osmoerythrograms. It is also characterized by similarly high levels of lysophospholipids both in whole blood and in isolated red blood cells and phosphatidylinositol levels which are lower than in metastasis-free cases. Red blood cells from cases of metastatic spreading revealed relatively lower values of the phosphatidylcholine/phosphatidylethanolamine ratio, too.
