Since the description of the first cases of infection in December 2019 in the Hubei province in China, a new coronavirus, called SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), emerged and caused a pandemic. This new virus is responsible for an infectious disease with respiratory and potent severe symptoms, called COVID-19 (coronavirus disease 2019). The first data concerned essentially the adult population and gave a clinical description of the disease. However, data is missing in the pediatric population. The first published studies indicate that children seem to have a lower risk to get a severe form of COVID-19. Except the case of a child with leukemia recently described with the diagnosis of COVID-19, there is currently no data about pediatric patients with an oncology history or under chemotherapeutic drugs. Cancers are rare among children and is estimated to concern about 1700 new cases in a year in France. Malignant tumor or its treatment can affect self-immunity, which could favor SARS-CoV-2 infection or its aggravation. Thus, the investigators propose in this study to collect data about French children with a cancer and diagnosed with COVID-19.The analysis of the collected data will refine clinical characteristics of SARS-CoV-2 infection in this population. It will be critical for elaborating recommendations for the management of COVID-19 in children with cancer.


Since the description of the first cases in December 2019, the world is facing the emergence of a new coronavirus called "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2), which is responsible for an infectious disease mainly with respiratory manifestation and potently severe or even lethal, named coronavirus disease 2019 (COVID-19) (N. Zhu et al. 2020; Huang et al. 2020). The global spread of this virus led to the development of an unprecedented pandemic with an huge impact on public health and from a social and economic point of view (Ayittey et al. 2020).

First published data mainly concerned the adult population with a detailed COVID-19 clinical description. Few data are available in children. However, the first studies suggest that children may be at a lower risk than adults of developing a severe form of COVID-19 (Guan et al. 2020; Lu et al. 2020; Sinha et al. 2020). Neonatal presentation may be more severe (H. Zhu et al. 2020). Children seem to present with similar symptoms compared with adults but often with a milder form (Cao et al. 2020). Radiological findings also appear to be similar to those in adults (Liu et al. 2020; Xia et al. 2020). Children may be asymptomatic and may participate in the spread of SARS-CoV-2 (Lu et al. 2020; Chan et al. 2020). Nevertheless, severe COVID-19 forms were described in children, even if deaths remain extremely rare (Sun et al. 2020; Lu et al. 2020). Among the previous described severe forms, one of the patient dependent on mechanic ventilation had acute lymphoblastic leukemia (Sun et al. 2020). The publication of Lu et al. probably refers to this patient and it appears that this patient was receiving a maintenance treatment (Lu et al. 2020). This patient presented a co-infection with influenza virus, which probably explained his aggravation (Sun et al. 2020).

To describe COVID-19 presentation in children, adolescent and young adults, this study will include all patients with the following criteria:

  • Patient followed-up in any French pediatric oncology and hematology center for a cancer or a benign tumor treated with chemotherapy, radiotherapy or a targeted therapy and with an oncologic treatment ongoing or terminated within the last 6 months, or with an hematopoietic stem cell transplantation history with an immunosuppressive treatment ongoing or terminated within the last 6 months, or a CAR-T cell therapy history


  • PCR or serologically-confirmed SARS-CoV-2 infection


-Clinical and radiological diagnosis of SARS-CoV-2 infection with the following criteria : At least two of the following signs (three if no history of contact with an individual with a confirmed COVID-19): fever, cough, loss of smell, loss of taste, myalgia, chest pain, breath shortness, rhinorrhea, acute respiratory signs, diarrhea, headache, recent lethargy, skin rash.


  • At least one abnormality compatible with COVID-19 on a chest computed tomography scan.

In all included patients, the following informations will be retrieved from their medical record :

  • socio-demographic and anthropometric data: age, sex, weight, height...
  • cancer history: type of cancer, severity, ongoing or 30-days past oncologic treatment, significant oncologic treatment with potent impact on COVID-19 evolution (lung surgery, lung radiotherapy...)
  • clinical symptoms at initial stage, at 10-15, 15-20, 20-30 days of evolution
  • biological signs at initial stage, at 10-15, 15-20, 20-30 days of evolution
  • radiological signs at initial stage and on the following exams
  • COVID-19 management data: oxygen, antiviral agents, antibiotics...
  • Evolutive data: resolution/aggravation of infection, potent sequelae...
