Objective: Recent studies demonstrated emerging evidence of the role of inflammation in the growth and recurrence of chronic subdural hematoma (cSDH). Red blood cell distribution width to platelet count ratio (RPR) is a novel biomarker for inflammation in cancer, cardiac, and inflammatory diseases.
Methods: The present retrospective study investigated the impact of RPR on recurrence after burr hole surgery for cSDH in 297 patients. The optimal cut-off value for RPR was defined as ≥0.0568 according to the receiver operating characteristic curve (AUC:0.64, 95%CI:0.55-0.72, p=0.007). Study cohort was dichotomized into low (n=157) and high (n=140) RPR groups.
Results: Significant differences between the groups were identified regarding ASA classification, and frequency of anticoagulant intake. Demographics, comorbidities, size, morphology, and mass effect of cSDH were homogeneously distributed among the RPR groups. Multivariable binary logistic regression analysis considering location, midline-shift, septation, RPR, anticoagulant intake, sex, and ASA classification revealed that an increased baseline RPR (≥0.0568, OR: 3.3, 95%CI: 1.5-7.1, p=0.002), and preoperative midline-shift (≥5 mm, OR: 2.7, 95%CI: 1.2-5.8, p=0.01) are independent predictors of recurrent cSDH.
Conclusion: The present findings suggest RPR as a novel inflammatory biomarker enabling risk stratification of recurrence after burr hole surgery for cSDH and might facilitate a tailored medical decision making.
