[Trace elements of bone tumors].

Area of Science:

• Nuclear Chemistry
• Oncology
• Trace Element Analysis

Context:

• Bone tumors represent a significant clinical challenge, necessitating improved diagnostic and characterization methods.
• Understanding the elemental composition of biological tissues is crucial for diagnosing and understanding disease processes.
• Neutron activation analysis (NAA) is a sensitive technique for quantifying elemental concentrations in various matrices.

Purpose:

• To measure and compare the concentrations of 11 trace elements in normal bone tissue and skeletal tumors.
• To investigate the relationship between trace element levels and the type/histogenesis of bone neoplasms.
• To assess the utility of trace element analysis in differentiating tumorous from healthy bone tissue.

Summary:

• Activation analysis using reactor neutrons quantified 11 trace elements (Sc, Fe, Co, Hg, Rb, Se, Ag, Sb, Cr, Zn, Tb) in 76 bone tumor specimens and 10 normal bone samples.
• Tumor tissues exhibited significantly higher concentrations and different dispersion patterns for several trace elements compared to normal bone.
• Specific trace element concentrations in tumors were found to be dependent on the neoplasm's type and histogenesis.

Impact:

• Establishes significant differences in trace element profiles between bone tumors and normal bone.
• Highlights the potential of trace element analysis as a biomarker for bone tumor characterization and diagnosis.
• Provides a foundation for further research into the role of specific elements in bone oncogenesis and progression.
