Background: Inborn Errors of Immunity (IEI) comprise several genetic anomalies that affect different components of the innate and adaptive responses, predisposing to infectious diseases, autoimmunity and malignancy. Different studies, mostly in adults, have reported a higher prevalence of cancer in IEI patients. However, in part due to the rarity of most of these IEI subtypes (classified in ten categories by the Primary Immunodeficiency Committee of the International Union of Immunological Societies), it is difficult to assess the risk in a large number of patients, especially during childhood.

An association of deletions in the IKZF1 gene (IKZF1del) with poor prognosis in acute lymphoblastic leukemia (ALL) has been demonstrated. Additional deletions in other genes (IKZF1plus) define different IKZF1del subsets. We analyzed the influence of IKZF1del and/or IKZF1plus in the survival of children with ALL.

Progressive nodular histiocytosis is a rare variant of non-Langerhans cell histiocytosis that affects the skin and mucous membranes and displays a progressive clinical course and poor response to treatment. We describe a case of severe progressive nodular histiocytosis harboring a KRAS p.G12S mutation in a 9-year-old boy, refractory to chemotherapy, who was successfully treated with the MEK inhibitor cobimetinib.

Introduction: Children with Down syndrome (DS) more commonly have acute lymphoblastic leukemia (ALL) and a lower survival rate than those without Down syndrome (WDS). We analyzed the clinical, demographic, and biological characteristics and treatment response of children with DS-ALL versus those WDS-ALL. Patients and methods: Patients with ALL between January 1990 and November 2016.

Article Synopsis
  • - Childhood acute leukemias and lymphomas have high survival rates, but can lead to second neoplasms (SN), with 1% of patients developing SN over nearly 30 years of study.
  • - Among the 34 patients with SN, the most common types included acute leukemias and various solid tumors, with a significantly longer latency period for solid tumors compared to hematological malignancies.
  • - Treatment of SN, considering previous therapy doses, resulted in a 67.6% complete remission rate, indicating that patients can have survival rates similar to those diagnosed with new cancers.

Objective: Prospective analysis of clinical characteristics and long-term treatment results of a pediatric cohort with Hodgkin lymphoma (HL) treated in a single institution with ABVD and restricted radiotherapy (RT).

Patients And Methods: Between September 2000 and December 2015, 165 new consecutive assessable patients with HL were registered at our institution. Lymphocyte predominant nodular HL was excluded.
