Clinical Report: Experiences in Clinical Implementation of Online Adaptive Radiotherapy for Prostate Cancer

Overview

This report details the implementation of online adaptive radiotherapy (oART) for prostate cancer, highlighting the efficiency improvements achieved through automated contouring and advanced imaging technology. The study involved 69 patients and 1366 adaptive sessions, demonstrating significant reductions in treatment times.

Background

Online adaptive radiotherapy (oART) represents a significant advancement in radiation therapy, allowing for real-time adjustments to treatment plans based on daily anatomical changes. This approach enhances target coverage and minimizes exposure to surrounding organs at risk, which is critical for improving patient outcomes. However, concerns regarding treatment duration and resource allocation may hinder its widespread adoption in clinical settings.

Data Highlights

Key Findings

• Automated posterior rectal wall contouring significantly reduced adaptation time.
• Installation of HyperSight improved image quality and workflow efficiency.
• Patients received a total of 20 fractions with varying prescribed doses based on the SIB concept.
• All patients had an ECOG performance score of 0-1, allowing outpatient treatment.
• CBCT-guided oART provided dosimetric advantages with shorter session times compared to MR-guided systems.

Clinical Implications

The findings suggest that integrating automated contouring and advanced imaging technologies can enhance the efficiency of oART, making it a more viable option for clinical practice. Training and optimized workflows are essential for successful implementation and sustainability of oART in radiation oncology.

Conclusion

The implementation of oART in prostate cancer treatment shows promise in improving treatment efficiency and patient outcomes. Continued advancements in technology and workflow optimization will be crucial for broader adoption in clinical settings.
