68 Ga-Trivehexin PET/CT in Metastatic Non-Small Cell Lung Cancer to the Brain

Area of Science:

• Oncology
• Molecular Imaging
• Biochemistry

Background:

• The tumor microenvironment is critical for cancer progression and therapeutic response.
• Alpha-v-beta-6 integrin (αvβ6) is upregulated in various carcinomas, correlating with poor prognosis.
• αvβ6 plays key roles in cancer invasion, apoptosis resistance, and matrix remodeling.

Purpose of the Study:

• To identify and develop novel radiotracers for noninvasive molecular imaging of tumor tissues.
• To investigate the potential of targeting αvβ6 integrin for cancer diagnosis and therapy.

Main Methods:

• Exploration of targeted molecules for molecular imaging.
• Assessment of radiotracer affinity for specific molecular targets.

Main Results:

• Alpha-v-beta-6 integrin (αvβ6) is a transmembrane receptor exclusively expressed in epithelial cells.
• 68Ga-Trivehexin demonstrates a high binding affinity (85%-88%) for the αvβ6 integrin.

Conclusions:

• Targeting αvβ6 integrin represents a promising strategy for developing novel cancer therapies.
• 68Ga-Trivehexin shows potential as a radiotracer for imaging αvβ6-expressing tumors.
