Ewing sarcoma in an infant and review of the literature

Abstract: Ewing sarcoma (ES) is a rare tumor in infants and prognosis is controversial. There are no standard recommendations for treatment in such very young patients. Generally, radiotherapy (RT) is not a part of treatment in infants due to the risk of severe late side effects. In this case report, we report a 7-month-old boy with diagnosis of left mastoid bone ES with lung metastases at diagnosis, showing a rapidly fatal outcome despite aggressive systemic chemotherapy and RT without surgery.

“…The majority of relapses occur within the first 2 years of diagnosis, with shorter periods to recurrence predicting worse long-term survival 19. There is evidence that infants with congenital EWS have increased risk of early death, but whether this is due to toxicity of chemotherapy or disease progression is unclear 20. Our patient completed all 14 cycles of chemotherapy and is in outpatient surveillance.…”

“…It is common in adolescents, and the incidence rate accounts for 10 to 15% of orthopedic tumors [2]. The peak incidence occurs at the age of 15, and the incidence rate in males is higher than in females, with a ratio of 3:2 [3]. Although Ewing sarcoma accounts for only 1% of human malignant tumors, it is extremely aggressive and can rapidly metastasize to the lung and other tissues.…”

“…The survival rate of patients is approximately 70% after five years and decreases sharply to 30% after 10 years. Tumor metastasis at the time of diagnosis further reduces the survival rate after five years to only 25% [3]. The poor survival rate of Ewing sarcoma has since gained awareness.…”
