Which tumor's management is typically wide margins with en bloc resection to ensure complete removal?

• A. Chondrosarcoma
• B. Osteosarcoma
• C. Ewing sarcoma
• D. Rhabdomyosarcoma

Answer: (A)

Chondrosarcoma is known for being relatively resistant to chemotherapy and radiotherapy and for infiltrating bone and surrounding soft tissues with finger-like extensions. Because of this, achieving durable local control relies on removing the tumor in one piece with a wide margin, known as an en bloc resection, to capture microscopic extensions and minimize local recurrence. By contrast, osteosarcoma and Ewing sarcoma are typically treated with systemic chemotherapy alongside surgery, so while negative margins are important, the emphasis is on multimodal therapy and possibly downstaging the tumor before resection. Rhabdomyosarcoma likewise uses a combination of chemotherapy, radiotherapy, and surgery, with margins important but not defined by the en bloc wide-margin approach as the primary strategy.
