[Global Trends Survey for Targeted Radionuclide Therapy]

Area of Science:

• Nuclear Medicine
• Radiological Technology
• Molecular Imaging

Background:

• Radionuclide therapy is increasingly vital for managing diseases globally.
• A comprehensive survey of radionuclide therapy research was conducted.

Purpose of the Study:

• To analyze research content, evaluation modalities, dosimetry, radionuclides, and geographical distribution of radionuclide therapy studies.
• To compare the current status of radionuclide therapy in Japan with global trends.

Main Methods:

• Reviewed 4199 science abstracts from major international conferences in 2016.
• Analyzed research focus, imaging modalities (PET, SPECT), dosimetry techniques, and researcher origins.

Main Results:

• The United States (11%) and Europe (13%) showed more targeted radionuclide therapy studies than Japan (4%).
• Radiopharmaceuticals not yet approved in Japan were utilized in some international studies.
• Dosimetry studies using PET or SPECT imaging were more prevalent in the US (37%) and Europe (25%) than in Japan (14%).

Conclusions:

• The survey highlights Japan's position relative to global advancements in radionuclide therapy.
• Identified key areas of focus and regional disparities in research and application.
