Lymphoblastic lymphomas in children ­ A single-center experience from Serbia.

ABSTRACT

Introduction: Intensive treatment protocols used for non-Hodgkin lymphoma in children lead to eventfree survival rates ranging from 80% to 90%. However, the results are less successful in developing countries. Lymphoblastic lymphoma (LBL) is the second most frequent type of lymphoma in children, contributing with about one third to all non-Hodgkin lymphoma in childhood. Objective: The aim of the study was to evaluate the results of LBL treatment in University Children's Hospital (UCH), Belgrade. Methods: A retrospective analysis of patient records at UCH from 1997 to 2015 was carried out in patients aged 0­18 years, in whom the diagnosis of LBL had been established. Twenty-two children were included in the analysis. Results: Mean age at diagnosis was 10 years, with preponderance of male patients. All patients were treated according to Berlin-Frankfurt-Münster-based chemotherapy protocols. With median follow-up of 91.5 months, five-year probability of event-free survival was 79.5% for all patients, while overall survival was 81.8%. Conclusion: Our results, although slightly inferior to those of leading international groups, reflect a good treatment outcome in our patients.
