Prognostic Factors and Treatment Outcome of Relapsing and Refractory Pediatric Mature B-cell Non-Hodgkin Lymphoma, Children's Cancer Hospital Egypt Experience.

Background: Relapsed non-Hodgkin lymphoma treated by chemotherapy and hematopoietic stem cell transplantation (HSCT) has a dismal prognosis.

Patients: It is a retrospective study, including pediatric patients diagnosed as mature B-cell non-Hodgkin lymphoma who were primarily refractory or relapsed over 8 years at CCHE. The aim of the study was to analyze the prognostic factors and outcomes of this group of patients.

Can FDG-PET replace biopsy for the evaluation of residual tumor in pediatric mature B-cell non-Hodgkin lymphoma?

Introduction: The aim of our study is to evaluate the role of F-labeled fluorodeoxy glucose positron emission tomography ( FDG-PET) scan for the detection of viable residual mass in pediatric mature B-cell non-Hodgkin lymphoma (NHL). This study also aims to detect the negative predictive value, positive predictive value (PPV), sensitivity, and specificity of FDG-PET.

Patients And Methods: A retrospective, cross-sectional nonrandomized study was carried out.
