- ABSTRACT: Background: MR perfusion imaging is a relatively new technique that may aid in identifying recurrent tumor (RT) in those with radically treated high-grade gliomas (HGG). We aim to assess the relationship between dynamic susceptibility contrast-enhanced MR perfusion (DSC-MRP) and overall survival to establish a baseline for future research and to determine the utility of DSC-MRP as a clinical decision-making and prognostic tool. Methods: We conducted a retrospective cohort study. Adults with pathologically confirmed HGG at the Juravinski Cancer Centre, Ontario between January 2011 and April 2014 with at least one post-treatment DSC-MRP were included. DSC-MRP was interpreted as positive or negative for tumor recurrence by experienced radiologists. The primary outcome was overall survival. Results: Sixty-one patients were enrolled. Median survival for patients with a positive DSC-MRP scan was 4.5 months compared with 10.2 months for those with a negative DSC-MRP scan (hazard ratio [unadjusted] = 2.51; 95% confidence interval = 1.10–5.67; p -value = 0.03). Multivariable modeling (adjusted) that included all pre-selected variables showed similar results. Conclusion: Survival time in patients with HGG is generally low, and almost all patients will demonstrate RT. Our data suggest a positive DSC-MRP correlates with lower overall survival and may signify the presence of highly active RT. These results generate a hypothesis that there may be a prognostic role for the use ofABSTRACT: Background: MR perfusion imaging is a relatively new technique that may aid in identifying recurrent tumor (RT) in those with radically treated high-grade gliomas (HGG).

RÉSUMÉ: Utiliser l'IRM de perfusion pour déterminer la survie globale de patients traités pour des gliomes de haut grade. Contexte : L'IRM de perfusion est une technique relativement nouvelle qui pourrait aider à identifier la récurrence tumorale dans le cas de gliomes de haut grade. Notre objectif est d'évaluer l'association pouvant exister entre les IRM de perfusion dynamique de contraste de susceptibilité ( dynamic susceptibility contrast-enhanced MR perfusion ) et la survie globale des patients afin d'établir des lignes directrices pour la recherche à venir et de déterminer l'utilité diagnostique de cette technique d'imagerie en ce qui concerne la prise de décisions cliniques. Méthodes : Nous avons ainsi effectué une étude de cohorte rétrospective incluant des patients adultes atteints de gliomes de haut grade. Ces patients du Juravinski Cancer Centre (Ontario) ont vu leur maladie être confirmée entre janvier 2011 et avril 2014. À la suite d'un traitement dans cet établissement, ils ont aussi bénéficié d'au moins une IRM de perfusion dynamique de contraste de susceptibilité. Un tel examen médical a été jugé positif ou non par des médecins radiologues expérimentés en tenant compte de la réapparition de tumeurs. Enfin, le principal indicateur évalué a été la survie globale des patients. Résultats : Soixante et un patients ont fait partie de cette étude. La survie globale médiane des patients dont l'IRM de perfusion dynamique de contraste de susceptibilité était positive était de 4, 5 mois comparativement à 10, 2 mois pour ceux dont la même IRM était négative (rapport de risque [sans ajustement] = 2, 51 ; IC 95 % = 1, 10 à 5, 67 ; p = 0, 03). Une approche de modélisation multi-variable (avec ajustement) ayant inclus toutes nos variables présélectionnées a produit des résultats semblables. Conclusion : La survie globale des patients atteints de gliomes de haut grade est généralement faible ; de plus, presque tous les patients vont finir par donner à voir une récurrence tumorale. Nos données suggèrent donc que les patients dont l'IRM de perfusion dynamique de contraste de susceptibilité était positive peuvent être associés à une survie globale plus faible, ce qui pourrait signifier la présence d'une tumeur récurrente fortement active. Ces résultats laissent à penser que l'IRM de perfusion dynamique de contraste de susceptibilité pourrait jouer un rôle diagnostique dans le suivi des tumeurs. Plus important encore, il est possible que ce biomarqueur soit utile dans le processus décisionnel qui concerne les plans de traitement et les soins palliatifs. … (more)
