Mature B-cell non-Hodgkin lymphoma (B-NHL) constitutes a collection of relatively rare pediatric malignancies. In order to utilize administrative data to perform large-scale epidemiologic studies within this population, a two-step process was used to assemble a 12-year cohort of B-NHL patients treated between 2004 and 2015 within the Pediatric Health Information System database. Patients were identified by ICD-9 codes, and their chemotherapy data were then manually reviewed against standard B-NHL treatment regimens. A total of 1,409 patients were eligible for cohort inclusion. This process was validated at a single center, utilizing both an institutional tumor registry and medical record review as the gold standards. The validation demonstrated appropriate sensitivity (91.5%) and positive predictive value (95.1%) to allow for the future use of this cohort for epidemiologic and comparative effectiveness research.

INTRODUCTION: Proteasome inhibitors have garnered interest as novel chemotherapeutic agents based on their ability to inhibit the growth of cancer cells by altering the balance of intracellular proteins. Initial clinical trials of this drug class focused on bortezomib, a reversible inhibitor of the 20S proteasome, with promising results for the treatment of adult hematologic malignancies, including multiple myeloma and non-Hodgkin lymphoma. AREAS COVERED: This article will review the use of bortezomib and other proteasome inhibitors in both adult and pediatric populations, with a focus on their use in pediatrics. Expert commentary: Bortezomib moved into the pediatric oncology arena with encouraging results in multiple early phase trials for relapsed acute lymphoblastic leukemia and acute myeloid leukemia. Bortezomib is also being studied in the treatment of non-malignant disorders, including antibody-mediated allograft rejection, graft-versus-host disease, and autoimmune cytopenias. The numerous applications of bortezomib have inspired the development of second-generation proteasome inhibitors.
