Post-Operative Dosing of Steroids Post Craniotomy for Brain Tumor (PODS)
Summary
This phase II trial tests the effect of decreasing (tapering) doses of dexamethasone on steroid side effects in patients after surgery to remove (craniotomy) a brain tumor. Steroids are the gold standard post-surgery treatment to reduce swelling (edema) at the surgical site to reduce neurological symptoms. Although, corticosteroids reduce edema, they have side effects including high blood sugar, high blood pressure, and can impair wound healing. Dexamethasone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response. It also works to treat other conditions by reducing swelling and redness. Tapering doses dexamethasone may decrease steroid side effects without increasing the risk of edema in patients with brain tumors after a craniotomy.
Detailed description
PRIMARY OBJECTIVES: I. The primary objective of this study is to evaluate the efficacy of a reduced dosage steroid schedule (RDS) in patients who have undergone craniotomy for high grade glioma (HGG), low grade glioma (LGG), brain metastasis (BM), and meningiomas as compared with the normal dosing schedule (NDS). II. RDS after undergoing craniotomy for brain tumor has no impact on length of stay, 30 day readmission, and need for repeat imaging when compared to NDS. SECONDARY OBJECTIVE: I. RDS after craniotomy for brain tumor has no impact on development of steroid related side effects (new onset or worsening hypertension, hyperglycemia, wound infection, impaired wound healing, steroid dependence, neuropsychiatric disturbance) when compared to NDS. TERTIARY/EXPLORATORY OBJECTIVE: I. RDS after craniotomy has no effect on lymphocyte count and differential at 10-14 days after surgery. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I (NDS): Patients receive tapering doses of dexamethasone on days 1-15. Patients also undergo blood sample collection at time of surgery, at follow up visits and optionally at wound check visit 10-14 days post operative at investigator availability. Patients additionally undergo magnetic resonance imaging (MRI) and computed tomography (CT) scan during inpatient stay as part of standard of care. ARM II (RDS): Patients receive tapering doses of dexamethasone on days 1-4. Patients may receive dexamethasone intravenously (IV) and restart the taper if clinically indicated. Patients also undergo blood sample collection at time of surgery, follow up visits and optionally at wound check visit 10-14 days post operative at investigator availability. Patients additionally undergo MRI and CT scan during inpatient stay as part of standard of care.

Outcome measures
Primary
Length of hospital stay
The two-sample t-test or Mann-Whitney U test utilized to estimate the differences between the two groups. General linear model employed in the multivariable analysis to estimate the adjusted difference in length of hospital stay between the two groups after adjusting for other factors.
Time frame: Up to 3 months
30-day repeat admission rate
Comparison between the two groups assessed using Fisher exact test or Chi-Square test. Logistic regression used to compare between the two groups after adjusting for other factors. Odds ratios (OR) and 95% confidence intervals (CIs) calculated to evaluate the strength of any association.
Time frame: At 30 days after surgery
Need for repeat head imaging
Comparison between the two groups assessed using Fisher exact test or Chi-Square test. Logistic regression used to compare between the two groups after adjusting for other factors. OR and 95% CIs calculated to evaluate the strength of any association.
Time frame: Up to 3 months
Secondary
Incidence of new neurologic deficit
Time frame: At less than 30 days and at 3 months
Breakthrough seizures
Time frame: Up to 30 days after surgery
Evidence of Worsening Cerebral Edema
Time frame: Between 5 and 30 days after surgery
Evaluation for Steroid Dependence
Time frame: At long term follow up to 3 months after surgery
Rate of new onset hypertension
Time frame: During inpatient stay up to 3 months after surgery
Rate of new onset hyperglycemia
Time frame: During inpatient stay up to 3 months after surgery
Evaluation for Wound infection or Delayed Wound Healing
Time frame: At 2 week wound check after surgery
Evaluation for Need for Psychiatric Consult or Neuropsychiatric Side Effects
Time frame: At 2 week follow up after surgery
Change in lymphocyte count and differential
Time frame: At baseline and 10-14 days post-operative
