Clinical Scorecard: Investigation of Thermo-Optical Surface Monitoring Combined with X-Ray Guidance in DIBH Radiotherapy for Breast Cancer Management
At a Glance
Category Detail
Condition Breast Cancer Key Mechanisms Thermo-optical surface monitoring combined with X-ray guidance for setup accuracy and motion monitoring. Target Population Female patients with breast cancer post-breast conserving surgery. Care Setting Radiotherapy treatment centers.
Key Highlights
ETD provides setup accuracy comparable to CBCT with lower radiation dose. Surface monitoring detected mid-treatment drift, corrected by X-ray guidance. Mean setup errors were not significantly different from zero after X-ray correction. Treatment duration did not significantly impact intra-fraction deviations. Calculated PTV margins were 5.10 mm (lateral), 5.22 mm (longitudinal), and 5.78 mm (vertical). Guideline-Based Recommendations
Diagnosis
Breast cancer diagnosis confirmed through clinical evaluation and imaging. Management
Utilization of DIBH technique to reduce cardiac and pulmonary radiation exposure. Monitoring & Follow-up
Employ thermo-optical surface monitoring and X-ray imaging for real-time tracking. Risks
Monitor for radiation-induced heart disease and lung injury. Patient & Prescribing Data
31 female patients aged 32 to 66 years with breast cancer.
All patients had KPS scores ≥ 90 and normal upper arm mobility.
Clinical Best Practices
Implement SGRT for positioning and motion monitoring in DIBH radiotherapy. Use low-dose imaging techniques for intra-fraction monitoring. Related Resources & Content
