ABSTRACT Background Little is known as yet about the outcome of SARS-CoV-2 infection in children being treated for cancer. Methods We collected information on the clinical characteristics and outcomes of a cohort of 29 children (16 females and 13 males, median age 7 years, range [0-16]) diagnosed with SARS-CoV-2 infection while on chemotherapy/immunotherapy (N=26), or after stem cell transplantation (N=3) during the peak of the epidemic in Italy. These patients suffered from leukemia (N=16), lymphoma (N=3), solid tumors (N=10), and Langerhans cell histiocytosis (N=1). Results The course of the disease was mild in all cases, with only 12 children developing symptoms (pneumonia in 3 cases), and none needing intensive care. Fifteen patients were hospitalized, including 7 asymptomatic patients. Nine patients (including 5 with no symptoms) were given hydroxychloroquine, and 3 of them were also given lopinavir/ritonavir. Conclusions SARS-CoV-2 infection seems to take a milder clinical course in children than in adults with cancer. Specific SARS-CoV-2 treatment seems unnecessary for most children. In the light of our findings, and albeit with the necessary caution, we suggest avoiding major changes to planned anticancer treatments in pediatric patients acquiring COVID-19.

BackgroundAnaplastic large cell lymphoma (ALCL) represents approximately 15% of all pediatric non‐Hodgkin lymphomas (NHL). It has distinct clinical features, including frequent involvement of extranodal sites and rare localization to the central nervous system (CNS). Despite varying treatment approaches the outcome of patients with ALCL has not significantly improved during the last two decades.ProcedureFrom October 1997 to beginning of 2000, newly diagnosed ALCL patients were enrolled into AIEOP LNH‐97 protocol for ALCL. Thereafter and until 2007, only CNS positive patients were included. AIEOP LNH‐97 was based on the BFM‐95 schema for ALCL and included six high‐dose chemotherapy courses. CNS prophylaxis was obtained with one intrathecal injection of chemotherapy in each course, whereas treatment of CNS involvement included three intrathecal injections without irradiation.ResultsThirty‐two patients were eligible for the study. Lymph‐node disease was the most frequent localization (69% of the cases), followed by mediastinal (25%), CNS (22%), bone marrow (16%), and skin (13%) involvement. Probabilities of overall survival (OS) and of event‐free survival (EFS) at 5 years for the whole population were 87% (SE 6%) and 68% (SE 8%), respectively.ConclusionsThis study confirmed that short pulse chemotherapy is an efficacious treatment option for first line therapy of pediatric ALCL, and that dose intensity may have some relevance for outcome, but not in all of the patients. Refinement and optimization of therapy strategies for ALCL may originate from a combination of clinical and biological prospective studies, as those in the pipeline of current international collaboration.

Background: Brentuximab vedotin (BV) is an antibody drug-conjugated anti-CD30 approved for the treatment of adult classical Hodgkin's lymphoma (HL), whereas it is considered as off-label indication in paediatrics. The aim of the study was to evaluate the safety and efficacy of BV to treat patients aged less than 18 years with refractory/relapsed HL. Materials and methods:In this multicentre, retrospective study, 68 paediatric patients who received at least one dose of BV between November 2011 and August 2020 were enrolled. A median of nine doses of BV were administered as monotherapy (n = 31) or combined with other therapies (n = 37). BV was administrated alone as consolidation therapy after stem cell transplantation (SCT) in 12 patients, before SCT in 18 patients, whereas in 15 patients it was used before and after SCT as consolidation therapy. Median follow-up was 2.8 years (range: 0.6-8.9 years). Results:The best response was observed in the 86% of patients; the overall response rate was 66%. The 3-year progression-free survival was 58%, whereas the overall survival was 75%. No statistically significant differences between patients treated with BV monotherapy or combination were highlighted. In multivariate analysis, patients with non-nodular sclerosis HL and not transplanted had an increased risk of failure.Overall, 46% of patients had grade 3-4 adverse events that led to BV discontinuation in five of them. Conclusion:In conclusion, our study confirms that BV was a safe and effective drug, able to induce complete remission, either as monotherapy or in association with standard therapy.
