Children with underlying cancer are often immunocompromised. Data on severity of coronavirus disease 2019 (COVID-19) in children with cancer and its outcomes is emerging. Treatment protocols of specific cancers are decided based on the infrastructure, availability of supportive-care, and logistic issues of the locality. The purpose of the study was clinical analysis of COVID-19 in children and adolescents with cancer. The retrospective observational study was conducted at a tertiary healthcare-center in East India. Children and adolescents (aged 0-19 years) with cancer and under treatment with reverse-transcriptase-polymerase-chain-reaction (RT-PCR) confirmed COVID-19 between 5-July-2020 and 5-December-2020 were studied. Median age of the 68 identified patients was six years. Acute leukemia was the most common (66%) diagnosis. COVID-19 was asymptomatic/mildly symptomatic in 91% and moderate to severe in only 9% of patients. Fever (87%) was the commonest symptom, followed-by cough/coryza (75%). Three patients with acute myeloid leukemia (AML) and severe/critical COVID-19 and associated neutropenic sepsis were required transfer to the intensive-care-unit (ICU) for management. Three (4.4%) patients succumbed with COVID-19. Delay in treatment was observed in 63.2% of patients, and the median duration of delay was 28 days after acquiring COVID-19. Median time to attain negative COVID-19 RT-PCR was 16 days, and eight patients were repeat positives. While pediatric and adolescent cancer patients on active treatment may have a higher risk of mortality from severe COVID-19 than their healthy counterparts, the risk may be much lower than deemed. It is essential to continue cancer therapy in these children. Delay in treatment remains a concern.
