Treatment of venous thromboembolism with tinzaparin in oncological patients.

Venous thromboembolism (VTE) is a major cause of morbidity and mortality in patients with cancer. For over a decade, the gold standard of treatment and secondary prevention of cancer-associated thrombosis (CAT) has been represented by low-molecular-weight heparins (LMWHs), which are currently recommended as the first-line treatment for CAT. Among the LMWHs that were more extensively tested in patients with CAT, tinzaparin is a LMWH produced by the enzymatic degradation of porcine-derived unfractionated heparin. The efficacy of tinzaparin in this setting is supported by well-grounded evidence. However, there is a need to discuss the positioning of tinzaparin in the continuously evolving treatment scenario of VTE therapy in cancer patients. In this paper, which was developed by a group of clinicians with wide experience in the treatment of VTE in cancer patients, we discuss the current therapeutic options and the role of tinzaparin for the treatment of CAT.
