Study Shows Traumatic Brain Injuries Linked to Higher Brain Cancer Risk in War Veterans

Reading Time: 2 minutes

In a landmark study, researchers have unearthed a significant link between traumatic brain injuries (TBIs) and an elevated risk of developing brain cancer in veterans of the Iraq and Afghanistan wars.

This study, published in JAMA Network Open, highlights a critical health concern for military personnel and veterans who have suffered head injuries during their service.

Primary brain cancer, while rare, is known for its grim prognosis and limited established risk factors. This study’s findings suggest that certain types of TBIs could be key risk factors for this devastating disease.

The study focused on a retrospective cohort of veterans who served in the Iraq and Afghanistan conflicts, utilising extensive data from the Veterans Affairs (VA) and Department of Defense (DoD) records. It spanned from October 2004 to September 2019 and included a cohort of 1,919,740 veterans. The key objective was to examine whether a history of TBI is associated with a higher incidence of brain cancer.

Veterans with a history of moderate to severe or penetrating TBIs were found to have a higher risk of developing brain cancer, as opposed to those who had mild TBIs or no TBIs at all. The study included a diverse cohort, with the majority being male (80.25%) and non-Hispanic White (63.11%), and had a median age of 31 years at the index date.

The link between moderate/severe and penetrating TBI and subsequent brain cancer is a novel finding, providing valuable insights into potential risk factors for brain cancer in veterans. This discovery could be pivotal in understanding brain cancer development and formulating preventive measures for those at risk.

Despite the robustness of the study, it had its limitations. For instance, reliance on ICD-9/10 codes meant that some TBIs treated outside the DoD and VA healthcare systems might have been missed. Additionally, a significant proportion of veterans (24.1%) were excluded from the analysis, primarily due to no healthcare encounters during the study period. Furthermore, the findings, predominantly from a young, male military population, might not be entirely generalizable to the broader population.

This study’s outcomes underscore the necessity for ongoing research into this rare yet severe condition. The results advocate for more attention to and research on brain cancer risks in veterans, especially those with a history of severe or penetrating TBIs. These findings are critical for informing medical professionals, veterans, and policymakers about the long-term health implications of TBIs sustained during military service.
