Up to 20% of the VTs are caused by cancer. Brain cancer is one of the cancer types that has\u00a0the strongest association with venous thrombosis. A cancer diagnosis followed by VT often means a worse prognosis for the patient. Therefore, identifying who would benefit from blood clot prophylaxis is of very high clinical importance.<\/p>\n<p>A study recently published in the journal &#8220;Blood&#8221; is aiming to find new ways to identify patients at high risk of developing blood clots. Julia Riedl and coauthors from the Medical University of Vienna in Austria suggest that protein called <em>podoplanin<\/em> can be used as a marker for increased risk of VT in patients with brain cancer. Austrian researchers investigated brain tumor tissues from biopsies of 213 patients included in the Vienna Cancer and Thrombosis Study. They discovered that <em>podoplanin<\/em> was detectable in tumor tissue in 70% of patients. The more <em>podoplanin<\/em> was present in the tumor tissue, the lower life expectancy the patient had.<\/p>\n<p>Patients with <em>podoplanin<\/em> positive tumors also had lower blood platelet counts and higher levels of the protein D-dimer. These parameters may indicate ongoing clotting of small blood vessels or generally lower threshold of the body for blood clotting. The authors suggest that <em>podoplanin<\/em> can be used to identify a group of brain cancer patients who could benefit from antithrombotic therapy to avoid VT as a complication of the cancer disease.<\/p>\n<p>When studied in mice with induced brain cancer, <em>podoplanin<\/em> could be blocked by an anti-<em>podoplanin<\/em> antibody. Treated animals lived longer than their untreated littermates. This finding indicates that <em>podoplanin<\/em> might be a target in the search of a drug for cancer therapy.<\/p>\n<p>The study by Julia Riedl and coauthors provides new insights into the development of VT in brain tumors and cancer treatment. Further investigations are needed to develop a prognostic tool to recognize patients who would benefit from thromboprophylaxis.<\/p>\n<p>Reference:<em>\u00a0<\/em>Riedl J, Preusser M, Nazari PMS, Posch F, Panzer S, Marosi C, Birner P, Thaler J, Brostjan C, L\u00f6tsch D, Berger W, Hainfellner JA, Pabinger I, Ay C. <a href=\"http:\/\/www.bloodjournal.org\/content\/early\/2017\/01\/10\/blood-2016-06-720714?sso-checked=true\">Podoplanin expression in primary brain tumors induces platelet aggregation and increases risk of venous thromboembolism.<\/a>\u00a0<em>Blood (2017).<\/em><\/p>\n<div class='wp_likes' id='wp_likes_post-946'><a class='like' href=\"javascript:wp_likes.like(946);\" title='Like' ><img decoding=\"async\" src=\"https:\/\/site.uit.no\/trec\/wp-content\/plugins\/wp-likes\/images\/like.png\" alt='' border='0'\/><\/a><span class='text'><b>2<\/b> people like this post.<\/span><\/p>\n<div class='like' ><a href=\"javascript:wp_likes.like(946);\">Like<\/a><\/div>\n<div class='unlike' ><a href=\"javascript:wp_likes.unlike(946);\">Unlike<\/a><\/div>\n<\/div>\n<iframe src=\"http:\/\/www.facebook.com\/plugins\/like.php?href=https%3A%2F%2Fsite.uit.no%2Ftrec%2F2017%2F01%2F26%2Fbor-pasienter-med-hjernesvulst-fa-forebyggende-blodproppbehandling-norskenglish%2F&amp;layout=standard&amp;show_faces=true&amp;width=450&amp;action=like&amp;colorscheme=light&amp;height=80\" scrolling=\"no\" frameborder=\"0\" style=\"border:none; overflow:hidden; width:450px; height:80px;\" allowTransparency=\"true\"><\/iframe>","protected":false},"excerpt":{"rendered":"<p>Av Nadezhda Latysheva Overingeni\u00f8r ved TREC Oversatt fra engelsk av Dana Meknas\u00a0 Journalist (English version below) Pasienter med kreft er utsatt\u00a0for \u00e5 f\u00e5 ven\u00f8s blodpropp (VT).
