Advances in Bone-targeted Drug Delivery Systems for Neoadjuvant Chemotherapy for Osteosarcoma

Area of Science:

• Oncology
• Pharmacology
• Biomedical Engineering

Background:

• Osteosarcoma treatment faces challenges in drug delivery to bone tissues and managing chemotherapy toxicity.
• Organ targeting is the most advanced strategy in current osteosarcoma targeted therapy.

Purpose of the Study:

• To review the current research status of targeted therapy for osteosarcoma.
• To summarize progress in bone-targeted drug delivery systems for neoadjuvant chemotherapy.
• To provide insights for developing novel, low-toxicity therapeutic strategies.

Main Methods:

• Literature review of targeted therapy and bone-targeted drug delivery systems for osteosarcoma.
• Analysis of current research stages and clinical transition challenges.
• Identification of future research directions in multi-target strategies.

Main Results:

• Bone-targeted drug delivery systems show potential for concentrating chemotherapy in bone, improving efficacy and reducing adverse effects.
• Most bone-targeted systems for osteosarcoma are still in experimental phases with a long path to clinical use.
• Combining new, polymolecular, and multi-pathway targets is crucial for future system development.

Conclusions:

• Bone-targeted drug delivery systems represent a promising avenue for enhancing osteosarcoma neoadjuvant chemotherapy.
• Significant challenges remain in translating experimental systems to clinical practice.
• Future research should focus on innovative multi-target approaches to optimize therapeutic outcomes and minimize toxicity.
