Abstract

Background: Venous thromboembolism (VTE) is a very common adverse event for astrocytoma patients, but validation of proposed risk biomarkers has been elusive. We examine whether the status of the isocitrate dehydrogenase (IDH) gene is a risk factor for the development of venous thromboembolism (VTE) in astrocytoma patients. Methods: We conducted a retrospective chart review of 282 astrocytoma patients enrolled in the PROACTIVE (Prospective Assessment of Correlative Biomarker) study at MD Anderson Cancer Center (MDACC) from 9/1/2000 until 12/31/2013. Results: We identified 282 astrocytoma patients consisting of 49 IDH mutant astrocytomas and 233 IDH wildtype astrocytomas. Glioblastoma was the initial histopathologic diagnosis in 30 (61.2%) of the IDH mutated astrocytomas compared to 227(97.4%) of the IDH wild type astrocytomas. VTE was identified in 52 (18.4%) of patients. VTE was diagnosed in 7 (14.3%) of the IDH mutated astrocytomas compared to 45(19.3%) of the IDH wild type astrocytoma s (p = 0.4094). Median time to VTE from diagnosis was 2.71 months. Median time to VTE from diagnosis was 2.6 months for IDH mutated astrocytomas compared to 3.06 months for the IDH wild type astrocytomas (p = 0.8663). Conclusions: IDH gene status did not appear as a significant risk factor for the development of venous thromboembolism (VTE) in our cohort of astrocytoma patients. Further research into potential biomarkers for VTE may be warranted.
