[Inhibition of platelet aggregation under estrogen-treatment in patients with carcinoma of the prostate (author's transl)]

Abstract

In patients with carcinoma of the prostate treated with estrogens platelet aggregation is increased. Patients with increased platelet aggregation have a high incidence of cardio-vascular and thrombo-embolic diseases. Platelet aggregation was measured by the platelet-aggregation test (PAT). Platelet aggregation was inhibited by administration of acetyl-salicylic acid (ASS) 2 times 500 mg daily. An aggregation inhibiting effect was found in all 38 patients. To reduce the cardio-vascular complications of estrogens in treating carcinoma of the prostate acetyl-salicylic acid as an adjunct therapy is recommended. A long-term study has been started.
