Clinical Scorecard: Dosimetric Evaluation of IMRT and VMAT Techniques with Deep Inspiration Breath Hold versus Free Breathing for Whole Breast Irradiation on the Right Side

At a Glance

Key Highlights

• DIBH significantly reduces radiation doses to the heart, liver, and lungs compared to FB.
• VMAT shows better target coverage and reduced high-dose exposure to the ipsilateral lung and liver than IMRT.
• DIBH can improve the therapeutic ratio for right breast radiotherapy.

Guideline-Based Recommendations

Diagnosis

• Patients should be evaluated for right-sided early-stage node-negative breast cancer.

Management

• Consider DIBH for right-sided WBI to minimize radiation exposure to OARs.

Monitoring & Follow-up

• Use dose-volume histograms (DVHs) to assess target coverage and OAR sparing.

Risks

• Monitor for potential increased mean heart and contralateral breast dose with VMAT.

Patient & Prescribing Data

Patients undergoing breast-conserving surgery and adjuvant radiotherapy for right-sided breast cancer.

DIBH and advanced planning techniques like IMRT and VMAT can optimize treatment outcomes.

Clinical Best Practices

• Utilize DIBH for right-sided breast cancer to enhance lung and liver sparing.
• Employ IMRT and VMAT techniques to improve dose conformity and homogeneity.
