What is the typical treatment sequence for Ewing sarcoma?

• A. Radiation Therapy Alone
• B. Chemotherapy Only
• C. Neoadjuvant Chemotherapy Followed by Surgical Resection
• D. Observation

Answer: (C)

Ewing sarcoma needs both systemic treatment and local control, and the standard approach starts with chemotherapy to address possible micrometastatic disease and shrink the tumor, making surgical removal more achievable. After several cycles of neoadjuvant chemotherapy, the surgeon removes the tumor when feasible to achieve clear margins, providing solid local control. Completion of systemic therapy after surgery helps reduce relapse risk. Radiotherapy is used selectively if surgery isn’t possible or margins are positive, but the typical sequence remains chemotherapy first, then surgery, with adjuvant chemotherapy as needed. This is why Neoadjuvant Chemotherapy Followed by Surgical Resection is the best fit. Radiotherapy alone or chemotherapy alone wouldn’t optimally address both systemic spread and local tumor control, and observation would miss the necessary treatment.
