Novel molecular and metabolic aspects in osteosarcoma

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Osteosarcoma (OS) is the most common bone cancer in children and adolescents.
• Its pathogenesis involves a complex interplay of genetic events, including oncogene activation and tumor suppressor gene downregulation.
• Epigenetic alterations like aberrant promoter methylation also contribute to gene deregulation in OS.

Purpose of the Study:

• To present novel molecular and metabolic advances in understanding Osteosarcoma.
• To analyze the genetic profile and biochemical microenvironment of OS.
• To explore the aggressive phenotype and high metastatic potential of OS.

Main Methods:

• Analysis of the genetic profile of Osteosarcoma.
• Assessment of the biochemical microenvironment in OS.
• Review of novel targeted therapies (monoclonal antibodies, tyrosine-kinase inhibitors) and diagnostic techniques (18F-FDG/PET/CT).

Main Results:

• Identification of a combination of genetic events, rather than a single gene, driving OS.
• Exploration of activated oncogenes and downregulated suppressor genes crucial for OS pathogenesis.
• Characterization of mechanisms of gene deregulation, including amplifications, mutations, allelic losses, and epigenetic abnormalities.
• Highlighting the aggressive phenotype and high metastatic potential of OS as areas needing further exploration.

Conclusions:

• Significant progress has been made in understanding the molecular basis of Osteosarcoma.
• Novel targeted therapies and advanced diagnostic techniques offer new avenues for OS treatment and management.
• Further research into the molecular and metabolic landscape is crucial for addressing the aggressive nature and metastatic potential of OS.
