Which statement is true regarding the management of Ewing sarcoma?

• A. Chemotherapy Is Never Used
• B. Neoadjuvant Chemotherapy Is Given Before Surgical Resection
• C. Radiotherapy Alone Cures Most Cases
• D. Observation Is Sufficient

Answer: (B)

Ewing sarcoma requires systemic treatment in addition to local control because micrometastatic disease is common at diagnosis. Giving chemotherapy before attempting surgical removal serves several key purposes: it shrinks the tumor to improve the chances of a complete resection, it treats distant microscopic disease early, and it provides a real-time gauge of how the tumor responds to chemo, which helps tailor further therapy. In practice, a multi-agent chemotherapy regimen is given in the neoadjuvant (preoperative) setting, followed by local control with surgery or radiotherapy and then additional chemotherapy to finish systemic treatment. Radiotherapy alone seldom cures, and simply observing would neglect the essential systemic component. Therefore, giving neoadjuvant chemotherapy before surgical resection aligns with the standard approach.
