Cancer and thrombosis

Osanto wonders why one person with cancer develops clotting and the other not. Cancer patients who do get thrombosis have a much worse prognosis than the other who don’t,
In blood of cancer patients who developed thrombosis, we found nanosized particles, presumably derived from the cancer cell itself, which expresses bound functionally active tissue factor (the initiator of the coagulation cascade). Such microparticle-associated active tissue factor would be able to  inititiate clotting in the body at far distance from the tumour.
Longitudinally collected blood samples (liquid biopsy) from well-characterized prostate cancer patients are being investigated for the presence of circulating tumour cells (CTCs) and possible expression of therapy-resistance (splice variants) of genes, DNA traces of the tumour itself (ctDNA) ad RNA.

Canter treatment may cause endothelium damage, with (fatal) arterial or venous thrombosis as result. In blood of such cancer patients we do not find MP-associated functional TF, but instead free radicals, free iron, iron overload, which may ultimately cause fatigue, metabolic syndrome, cardiovascular disease and organ damage. 
Awareness of physician and patient, lifestyle coaching, en further research, may eventually lead to better preventive strategies.
