Perihematomal Edema After Intracerebral Hemorrhage in Patients With Active Malignancy.

ABSTRACT: Background and Purpose- Patients with active malignancy are at risk for intracerebral hemorrhage (ICH). We aimed to characterize perihematomal edema (PHE) and hematoma volumes after spontaneous nontraumatic ICH in patients with cancer without central nervous system involvement. Methods- Patients with active malignancy who developed ICH were retrospectively identified through automated searches of institutional databases. Control patients were identified with ICH and without active cancer. Demographic and cancer-specific data were obtained by chart review. Hematoma and PHE volumes were determined using semiautomated methodology. Univariate and multivariate linear regression models were created to assess which variables were associated with hematoma and PHE expansion. Results- Patients with cancer (N=80) and controls (N=136) had similar demographics (all P>0.20), although hypertension was more prevalent among controls (P=0.004). Most patients with cancer had received recent chemotherapy (n=45, 56%) and had recurrence of malignancy (n=43, 54%). Patients with cancer were thrombocytopenic (median platelet count 90?000 [interquartile range, 17?500-211?500]), and most had undergone blood product transfusion (n=41, 51%), predominantly platelets (n=38, 48%). Thirty-day mortality was 36% (n=29). Patients with cancer had significantly increased PHE volumes (23.67 versus 8.61 mL; P=1.88×10^-9) and PHE-to-ICH volume ratios (2.26 versus 0.99; P=2.20×10^-16). In multivariate analyses, variables associated with PHE growth among patients with cancer were ICH volume (?=1.29 [95% CI, 1.58-1.30] P=1.30×10^-5) and platelet transfusion (?=15.67 [95% CI, 3.61-27.74] P=0.014). Variables associated with 30-day mortality were ICH volume (odds ratio, 1.06 [95% CI, 1.03-1.10] P=6.76×10^-5), PHE volume (odds ratio, 1.07 [95% CI, 1.04-1.09] P=7.40×10^-6), PHE growth (odds ratio, 1.05 [95% CI, 1.01-1.10] P=0.01), and platelet transfusion (odds ratio, 1.48 [95% CI, 1.22-1.79] P=0.0001). Conclusions- Patients with active cancer who develop ICH have increased PHE volumes. PHE growth was independent of thrombocytopenia but associated with blood product transfusion. Thirty-day mortality was associated with PHE and ICH volumes and blood product transfusion.

Project description:Background and Purpose- It is unknown whether blood pressure (BP) reduction influences secondary brain injury in spontaneous intracerebral hemorrhage (ICH). We tested the hypothesis that intensive BP reduction is associated with decreased perihematomal edema expansion rate (PHER) in deep ICH. Methods- We performed an exploratory analysis of the ATACH-2 randomized trial (Antihypertensive Treatment of Acute Cerebral Hemorrhage-2). Patients with deep, supratentorial ICH were included. PHER was calculated as the difference in perihematomal edema volume between baseline and 24-hour computed tomography scans divided by hours between scans. We used regression analyses to determine whether intensive BP reduction was associated with PHER and if PHER was associated with poor outcome (3-month modified Rankin Scale score 4-6). We then used interaction analyses to test whether specific deep location (basal ganglia versus thalamus) modified these associations. Results- Among 1000 patients enrolled in ATACH-2, 870 (87%) had supratentorial, deep ICH. Of these, 780 (90%) had neuroimaging data (336 thalamic and 444 basal ganglia hemorrhages). Baseline characteristics of the treatment groups remained balanced (P>0.2). Intensive BP reduction was associated with a decrease in PHER in univariable (β= -0.15; 95% CI, -0.26 to -0.05; P=0.007) and multivariable (β=-0.12; 95% CI, -0.21 to -0.02; P=0.03) analyses. PHER was not independently associated with outcome in all deep ICH (odds ratio, 1.14; 95% CI, 0.93-1.41; P=0.20), but this association was modified by the specific deep location involved (multivariable interaction P=0.02); in adjusted analyses, PHER was associated with poor outcome in basal ganglia (odds ratio, 1.42; 1.05-1.97; P=0.03) but not thalamic (odds ratio, 1.02; 95% CI, 0.74-1.40; P=0.89) ICH. Conclusions- Intensive BP reduction was associated with decreased 24-hour PHER in deep ICH. PHER was not independently associated with outcome in all deep ICH but was associated with poor outcome in basal ganglia ICH. PHER may be a clinically relevant end point for clinical trials in basal ganglia ICH.
