Do chondrosarcomas respond to chemotherapy?

• A. Yes
• B. No
• C. Only in pediatric cases
• D. Unproven in adults

Answer: (B)

Chondrosarcoma is generally chemoresistant because many tumors have a slow growth rate and are embedded in a dense cartilaginous matrix with limited blood vessel supply. This combination makes it hard for drugs to reach tumor cells and for those cells to respond, since chemotherapy mainly targets rapidly dividing cells. As a result, the standard approach is surgical resection with clear margins, with radiotherapy used selectively in certain cases. While rare subtypes (like dedifferentiated or mesenchymal variants) may show some sensitivity in particular scenarios, the typical chondrosarcoma in adults does not respond to chemotherapy.
