Which statement about chondrosarcoma is supported by the material?

• A. It develops at the costochondral junction and is not chemo responsive
• B. It is best treated with radiation therapy alone
• C. It commonly responds to chemotherapy
• D. It is typically managed with observation

Answer: (A)

Chondrosarcoma of the chest wall behaves as a malignant cartilage-producing tumor that most often involves the rib cartilage and the costochondral junction. Its biology makes it poorly responsive to chemotherapy, and radiotherapy alone rarely achieves cure; the tumor is best controlled with wide surgical resection aiming for clear margins. This combination—arising at the costochondral junction and lacking chemo responsiveness—fits the typical clinical picture and is why this statement is the most accurate. In practice, chemotherapy is not relied upon for cure, radiation is usually not enough by itself, and observation would miss a malignant process that needs definitive surgical removal.
