The International Initiative on Thrombosis and Cancer (ITAC), founded in 2013, is the international branch of the Groupe Francophone Thrombose et Cancer (GFTC), a French not for profit clinical research organization. Our mission is accomplished through the dissemination of educational initiatives to physicians, nurses, and allied healthcare professionals worldwide, which are developed according to evidence-based clinical practice guidelines for the treatment and prophylaxis of VTE in cancer patients, including those published by ITAC. We have also produced a free interactive guideline app, which is currently available for iOS and Android, in five languages: English, French, Spanish, Portuguese and Russian.
