[Immunity and cancer associated thrombosis]

In cancer patients, thrombosis is commonly found complication. There are many established risk factors which may be responsible for thrombosis in this group of patients. Especially the factors connected with treatment and the cancer itself, seem to be significant in the pathogenesis of thromboembolism. On the other hand, the reactions between cancer, hemostasis and immunological system seem to be important in initiation of the thrombotic process. In this review, on the basis of current literature, we have analyzed the relationship between neoplasmatic thrombosis and immunological disorders. The lack of balance between immunological system and haemostasis in neoplasms is the key issue to solve, in order to correct the long term cancer survival.
