Fosaprepitant use in children and adolescents at Memorial Sloan Kettering Cancer Center.

10575Background: Recent NCCN guidelines recommend the addition of a neurokinin-1(NK1) receptor antagonist (e.g. fosaprepitant) to the serotonin 5-hydroxytryptamine type 3 (5-HT3) receptor antagonist-corticosteroid combination for controlling both acute and delayed chemotherapy induced nausea and vomiting(CINV) associated with high emetogenic chemotherapy (HEC) in adults. Fosaprepitant is bioequivalent to aprepitant and could offer benefits to patients who are unable to tolerate oral antiemetics. However, little is known about the efficacy and safety of fosaprepitant in children. Methods: This retrospective chart review included all pediatric patients less than 18 years of age who received fosaprepitant at Memorial Sloan Kettering Cancer Center from July 2011 to November 2016. Results: Thirty-one patient charts representing a total of 105 doses of fosaprepitant were reviewed. Median age was 15 (range 2-17) years. Fifty-one doses (49%) were administered for primary prophylaxis for 11 patients; 40 doses (38%...
