Which tumor type is reported to respond best to radiation therapy?

• A. Neuroblastoma
• B. Leukemia
• C. Osteosarcoma
• D. Melanoma

Answer: (A)

Radiosensitivity varies by tumor type, and some cancers are particularly responsive to radiation for local control. Neuroblastoma often shows good responsiveness to radiation, so external beam radiation is a common part of multimodal treatment to achieve local control after chemotherapy and surgery in many cases. In contrast, leukemia is a systemic disease where chemotherapy is the main treatment, with radiation used only for specific indications; melanoma tends to be more resistant to radiation, and osteosarcoma is generally less radiosensitive, with surgery and chemotherapy as the primary approach. So, among these options, neuroblastoma is the best responder to radiation therapy.
