Early Post-Therapy Prescription Drug Usage among Childhood and Adolescent Cancer Survivors.

Objective: To describe the patterns of prescription drug use among child and adolescent survivors of cancer in the early post-therapy period compared with matched peers without a cancer history.

Study Design: Using the MarketScan commercial insurance claims database, we performed a retrospective cohort study identifying survivors of pediatric (0-21 years of age at diagnosis) leukemia, lymphoma, central nervous system, bone, or gonadal cancers who completed therapy from 2000 to 2011 and remained insured for 3 years post-therapy. Prescription fills during the first 3 years post-therapy were examined, categorized by drug class, and compared with age-, sex-, and region-matched individuals without cancer.
