**4. Conclusions**

COVID-19 infection is mild in children. However, the outcomes of COVID-19 in children with cancer are worse than the healthy children. Therefore, cancer treatment initiation should not be postponed for curable cancers. Treatment of COVID-19 in children with cancer is the same with healthy children with COVID-19. Therefore, Hydroxychloroquine plus azithromycin is no longer used; in the panel, remdesivir is recommended. In Turkey, favipiravir is used. MIS-C is a critical and late complication of COVID-19. Vaccination is recommended. However, the vaccine studies of COVID 19 in children are not completed [50]. Following the recent guidelines, multidisciplinary teamwork is essential for deciding the management of children with cancer.
