B-Lymphoblastic Lymphoma in Children: A Case Series From a Single Institution.

BACKGROUND: Pediatric B-lymphoblastic lymphoma is an uncommon subtype of non-Hodgkin lymphoma. Studies regarding the biology, clinical course, and approach to relapse are limited. OBSERVATIONS: We present a series of children with B-lymphoblastic lymphoma to describe the clinical course at diagnosis and relapse as well as the role of tumor cytogenetics, immunotherapy, and hematopoietic stem cell transplant. CONCLUSIONS: The prognostic significance of cytogenetic changes in B-lymphoblastic lymphoma is not well described but may offer improved risk stratification. Immunotherapy may offer salvage options for relapsed disease and can serve as a bridge to transplant.
