How Osteosarcoma Medications Work

Osteosarcoma is a type of bone cancer that requires a multi-modal treatment approach. While surgery remains the gold standard for treating osteosarcoma, medications play a crucial role in managing symptoms and improving outcomes.

Chemotherapy: Adjuvant Therapy

• How it works: Chemotherapy uses cytotoxic agents to kill cancer cells that may have spread beyond the primary tumor site. These agents target rapidly dividing cells, including cancer cells.
• Examples of chemotherapy drugs used in osteosarcoma: Methotrexate, Doxorubicin, and Cisplatin are commonly used to treat osteosarcoma.

Molecularly Targeted Therapy and Checkpoint Inhibitors

• How it works: Molecularly targeted therapy uses drugs that specifically target cancer cells with specific genetic mutations or molecular characteristics. Checkpoint inhibitors, on the other hand, release the brakes on the immune system to allow it to attack cancer cells.
• Examples of targeted therapy and checkpoint inhibitors used in osteosarcoma: Drugs such as Pazopanib (a tyrosine kinase inhibitor) and Pembrolizumab (a checkpoint inhibitor) are being investigated for their potential to treat osteosarcoma.

Immunotherapy: Checkpoint Inhibitors

• How it works: Checkpoint inhibitors work by releasing the brakes on the immune system, allowing it to attack cancer cells more effectively. This approach has shown promise in treating various types of cancer, including osteosarcoma.
• Examples of checkpoint inhibitors used in osteosarcoma: Pembrolizumab and Nivolumab are being investigated for their potential to treat osteosarcoma.
