ABSTRACT
OBJECTIVE: The objective of this study was to assess the clinical impact and outcome of the SARS-CoV-2 infection on children with cancer or those who received a hematopoietic stem cell transplantation. METHODS: AIEOP (Italian Association of Pediatric Hematology and Oncology) performed a nationwide multicenter observational cohort study, including consecutive patients between April 2020 and November 2022. RESULTS: Twenty-five Italian centers participated and 455 patients were enrolled. We reported a significant increasing trend of symptomatic cases over the years, while the number of nonmild infections remained stable. Early infection after oncologic diagnosis (<60 days) and severe neutropenia were identified as independent risk factors for developing moderate, severe, or critical infections. The percentage of patients who were asymptomatic and mildly symptomatic and who stopped chemotherapy reduced over the years of the pandemic. Nine patients died, but no death was attributed to SARS-CoV-2 infection. CONCLUSIONS: SARS-CoV-2 infection presented a self-limiting benign course in the Italian pediatric oncohematology population during the pandemic, and its main consequence has been the discontinuation of cancer-directed therapies. The rate of patients who were asymptomatic and stopped chemotherapy reduced over the years, suggesting that the continuation of chemotherapy is a feasible option.

COVID-19 has a mild clinical course with low mortality rate in general pediatric population, while variable outcomes have been described in children with cancer. Infectious diseases working party of the AIEOP collected data on the clinical characteristics and outcomes of SARS-CoV-2 infections in pediatric oncology/hematology patients from April 2020 to May 2021, including the second and the third waves of the pandemic in Italy. Factors potentially associated with moderate, severe, or critical COVID-19 were analyzed. Of the 153 SARS-Cov2 infections recorded, 100 were asymptomatic and 53 symptomatic. The course of COVID-19 was mild in 41, moderate in 2, severe in 5, and critical in 5 children. A total of 40.5% of patients were hospitalized, ten requiring oxygen support and 5 admitted to the intensive care unit. Antibiotics and steroids were the most used therapies. No patient died due to SARS-CoV-2 infection. Infections occurring early (< 60 days) after the diagnosis of the underlying disease or after SCT were associated to moderate, severe, and critical disease compared to infections occurring late (> 60 days) or during maintenance therapy. In the patients on active chemotherapy, 59% withdrew the treatment for a median of 15 days. SARS-CoV-2 presented a favorable outcome in children with cancer in Italy during the pandemic. Modification of therapy represents a major concern in this population. Our findings suggest considering regular chemotherapy continuation, particularly in patients on maintenance therapy or infected late after the diagnosis.

Medulloblastoma is the most common malignant brain tumor in children. Even if current treatment dramatically improves the prognosis, survivors often develop long-term treatment-related sequelae. The current radiotherapy standard for medulloblastoma is craniospinal irradiation with a boost to the primary tumor site and to any metastatic sites. Proton therapy (PT) has similar efficacy compared to traditional photon-based radiotherapy but might achieve lower toxicity rates. We report on our multi-centric experience with 43 children with medulloblastoma (median age at diagnosis 8.7 years, IQR 6.6, M/F 23/20; 26 high-risk, 14 standard-risk, 3 ex-infant), who received active scanning PT between 2015 and 2021, with a focus on PT-related acute-subacute toxicity, as well as some preliminary data on late toxicity. Most acute toxicities were mild and manageable with supportive therapy. Hematological toxicity was limited, even among HR patients who underwent hematopoietic stem-cell transplantation before PT. Preliminary data on late sequelae were also encouraging, although a longer follow-up is needed.
ABSTRACT
Vaccines represent the best tool to prevent the severity course and fatal consequences of the pandemic by the new Coronavirus 2019 infection (SARS-CoV-2). Considering the limited data on vaccination of pediatric oncohematological patients, we developed a Consensus document to support the Italian pediatric hematological oncological (AIEOP) centers in a scientifically correct communication with families and patients and to promote vaccination. The topics of the Consensus were: SARS-CoV-2 infection and disease (COVID-19) in the pediatric subjects; COVID-19 vaccines (type, schedule); who and when to vaccinate; contraindications and risk of serious adverse events; rare adverse events; third dose and vaccination after COVID-19; and other general prevention measures. Using the Delphi methodology for Consensus, 21 statements and their corresponding rationale were elaborated and discussed with the representatives of 31 centers, followed by voting. A high grade of Consensus was obtained on topics such as the potential risk of severe COVID-19 outcome in pediatric oncohematological patients, the need for vaccination as a preventative measure, the type, schedule and booster dose of vaccine, the eligibility of the patients for vaccination, and the timing, definition, and management of contraindications and serious adverse events, and other general prevention measures. All 21 of the statements were approved. This consensus document highlights that children and adolescents affected by hematological and oncological diseases are a fragile category. Vaccination plays an important role to prevent COVID-19, to permit the regular administration of chemotherapy or other treatments, to perform control visits and hospital admissions, and to prevent treatment delays.
ABSTRACT
Despite the finding of elevated Tricuspid Regurgitant Velocity (TRV) in children below 5 years of age, the prevalence and evolution of Pulmonary Hypertension (PH) in young children with sickle cell disease (SCD) are unclear. In order to identify predictive factors of precocious PH development, SCD children > or =3 years old, at steady state, underwent annual echocardiography and Tissue Doppler Imaging (TDI). Patients receiving chronic transfusion were excluded. Thirty-seven of seventy-five patients were > or =3 years, with measurable TRV. In our young population (mean age 6.2 years) of mainly African, HbS/HbS patients, 8/37 (21.6%) had TRV > or =2.5 m/s, 8% being only 3 years old. Significant correlation was found between precocious TRV elevation and high platelet and reticulocyte counts and frequent acute chest syndromes (ACS). In multivariate analysis, ACS was the only variable predicting TRV > or =2.5 m/s. TDI of the 37 patients showed signs of diastolic dysfunction of the left ventricle. At follow-up all eight patients with high TRV displayed further increase and seven more developed TRV > or =2.5 m/s. PH seems to begin in children earlier than expected. Factors involved in its early onset might be different from the ones causing its development in older children or adults. African children might benefit from early screening and re-assessment once a year.

Rhabdomyosarcoma is the most common soft-tissue sarcoma of childhood. Despite clinical advances, subsets of these patients continue to suffer high morbidity and mortality rates associated with their disease. Following the European guidelines for 18F-FDG PET and PET-CT imaging in pediatric oncology, the routine use of 18F-FDG PET-CT may be useful for patients affected by rhabdomyosarcoma, in staging, in the evaluation of response to therapy, and for restaging/detection of relapse. The European Pediatric Protocols are very old, and for staging and restaging, they recommend only radionuclide bone scan. The 18F-FDG PET-CT exam is listed as an optional investigation prescribed according to local availability and local protocols in the investigations panel required at the end of the treatment. We present two cases highlighting the usefulness of 18F-FDG PET-CT in managing pediatric patients affected by rhabdomyosarcoma, providing some bibliographic references.
ABSTRACT
BACKGROUND: Little is known as yet about the outcome of severe acute respiratory syndrome coronavirus 2 (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 female and 13 male; median age, 7 years [range, 0-16 years]) 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. Among the 26 patients on chemotherapy/immunotherapy, the treatment was suspended in 16 cases for a median of 26 days (range, 15-68 days), whereas 8 patients continued their chemotherapy and 2 had minor modifications to their treatment regimen. 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 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.
