Treatment planning in molecular radiotherapy

Area of Science:

• Medical Physics
• Nuclear Medicine
• Radiotherapy

Background:

• Molecular radiotherapy involves administering radionuclides or radiolabeled pharmaceuticals.
• Treatment planning requires determining the optimal administered activity.
• The goal is to maximize tumor cell sterilization while minimizing normal tissue damage.

Purpose of the Study:

• To present and compare different approaches for determining optimal radionuclide activity in molecular radiotherapy.
• To discuss the trade-offs between cohort-based and patient-specific dosimetry methods.
• To propose a general scheme for data collection and analysis in treatment planning.

Main Methods:

• Review of existing methods for activity determination in molecular radiotherapy.
• Comparison of cohort-based and patient-specific dosimetry approaches.
• Proposal of a framework for data collection and analysis.

Main Results:

• Different approaches to activity determination vary in input complexity, cost, and therapeutic quality.
• Patient-specific dosimetry, utilizing individual biokinetics, offers a more tailored approach.
• Effective and safe treatment requires comprehensive data collection and robust analysis.

Conclusions:

• Optimizing administered activity is crucial for effective molecular radiotherapy.
• Patient-specific dosimetry and data analysis are key challenges and opportunities.
• Further development in data handling is needed for improved treatment outcomes.
