INTRODUCTION
More than a year into the COVID-19 pandemic, its impact on children with cancer is still not fully described. In addition to the direct infectious risk among children undergoing treatment, pediatric oncologists in high-income countries have noted an increased incidence of delayed diagnosis and treatment.1 Though issues like under-diagnosis and abandonment of treatment were major issues in low- and middle-income countries (LMIC) prior to the pandemic, whether these have worsened because of COVID-19 is suspected but not known.2 We therefore aimed to assess the impact of the pandemic in one Indonesian tertiary hospital upon the rate of new diagnoses and abandonment rates.
