Optimizing SBRT Treatment Planning for Lung Cancer

SBRT has revolutionized early-stage NSCLC treatment. This guide explores evidence-based strategies for optimizing treatment planning.

Key Planning Objectives

• Tumor Coverage: 95-99% PTV coverage
• Dose Conformity: CI of 1.0-1.2
• Gradient Index: GI < 5.0
• OAR Sparing: Strict dose constraints

Conclusion

Optimizing SBRT requires meticulous attention to target delineation, dose prescription, and quality assurance.
