From Bench to Bedside: Advancements in Precision Oncology and Drug Discovery for Osteosarcoma

Osteosarcoma remains a highly aggressive malignancy with limited therapeutic progress and poor outcomes, particularly in metastatic or recurrent cases. Conventional treatment approaches, primarily based on surgery and high-dose chemotherapy, are hindered by significant drawbacks, including severe toxicity, high relapse rates, and drug resistance, underscoring the inadequacy of current standard approaches. This review examines emerging advances in precision medicine and drug discovery, including targeted inhibitors, immunomodulatory agents, combination treatments, and advanced biomaterials, that promise to transform osteosarcoma care. Recent advances, such as combinations of immune checkpoint inhibitors with novel agents or nanoparticle-based drug delivery systems, as well as <i>CRISPR-Cas9</i> gene-editing applications, offer new strategies to overcome the inherent challenges of conventional therapies. In addition, cutting-edge research leveraging multi-omics analyses and digital pathology is refining our understanding of the tumour microenvironment, paving the way for more individualised treatment strategies.
