Summary
A new cloud-based automated treatment planning system (Desargues Cloud TPS) offers efficient intensity-modulated radiation therapy planning. It demonstrates comparable or superior efficacy and safety to traditional methods, enhancing treatment delivery.
Area of Science:
- Radiation Oncology
- Medical Physics
- Computational Biology
Background:
- Intensity-modulated radiation therapy (IMRT) planning is complex and time-consuming.
- Automated treatment planning systems aim to improve efficiency and consistency.
- Cloud-based solutions offer potential for accessibility and scalability in radiotherapy.
Purpose of the Study:
- To develop and evaluate a novel cloud-based automated treatment planning system (Desargues Cloud TPS) for IMRT.
- To assess the efficacy and safety of the system across various tumor sites.
- To compare the performance of the automated system against traditional manual planning.
Main Methods:
- Development of a browser/server-based cloud system (Desargues Cloud TPS) integrating knowledge-based planning (KBP) and protocol-based automatic iterative optimization (PB-AIO).
- Multi-center clinical validation involving 53 patients, generating three IMRT plans per patient: automatic (Plan A), automatic with manual adjustment (Plan B), and fully manual (Plan C on Varian Eclipse).
- Evaluation of efficacy indicators (heterogeneity index, conformity index, plan quality metric, operation time) and safety indicators (gamma indices for dose verification).
Main Results:
- All plans met the PTV prescription dose coverage requirement (≥95%).
- Plans A and B showed significantly superior plan quality metrics (PQM), overall operation time (OOT), and plan optimization time (POT) compared to Plan C, except for the conformity index (CI) of Plan A.
- No statistically significant difference was found in dose accuracy (gamma indices) between Plan B and Plan C, indicating comparable safety.
Conclusions:
- The Desargues Cloud TPS demonstrates comparable overall efficacy and safety to Varian Eclipse for IMRT.
- Automatic planning with or without manual adjustments can yield superior results compared to fully manual planning.
- The cloud-based system enhances treatment planning efficiency and facilitates knowledge sharing in radiotherapy.
