Abstract
Indolent lymphomas are rare in children and mostly consist of pediatric type follicular (PTFL) and pediatric marginal zone lymphomas (PMZL) and extranodal marginal zone lymphoma (ENMZL). Twenty children with indolent lymphoma (10 PTFL, 6 PMZL, 3 ENMZL, 1 mixed type) among 307 Non-Hodgkin Lymphoma (NHL) were retrospectively evaluated. The mean age of the entire group was 10.4 ± 4.4 and was significantly lower in PTFL than in PMZL. Seven patients (35%) had an associated inborn error of immunity (IEI) which was higher than that seen in aggressive lymphomas (5.9%) (p < 0.0001). Seventeen patients (85%) had stage I/II disease. Two patients received no treatment after surgery. Eleven patients were treated only with 3-6 courses of rituximab. Four patients received 3-6 courses of R-CHOP protocol. The prognosis was excellent Five years overall and event-free survivals were 100% and 85%, respectively.
期刊介绍：
Leukemia & Lymphoma in its fourth decade continues to provide an international forum for publication of high quality clinical, translational, and basic science research, and original observations relating to all aspects of hematological malignancies. The scope ranges from clinical and clinico-pathological investigations to fundamental research in disease biology, mechanisms of action of novel agents, development of combination chemotherapy, pharmacology and pharmacogenomics as well as ethics and epidemiology. Submissions of unique clinical observations or confirmatory studies are considered and published as Letters to the Editor
