PHASE I - II STUDY OF PRONE ACCELERATED BREAST AND NODAL IMRT(Intensity-Modulated Radiation Therapy)
In Brief
A clinical study evaluating Intensity-modulated radiation therapy (IMRT) for Lymphedema. Completed, enrolled 97 participants across 1 site.
Detailed Summary
Following consent, patients will receive 15 fractions of radiotherapy to the affected breast and to Axillary level III and SCV (Supra-Clavicular) lymph nodes, defined by CT imaging obtained in a prone position using IMRT(intensity modulation radiation therapy ) technique: one fraction daily for 5 days/week for 3 consecutive weeks. Patients will be seen for follow-up at 45-60 days from first radiotherapy treatment, and then yearly. Patients will be assessed for Lymphedema at baseline, end of treatment, and at yearly intervals after completion of radiotherapy. All patients will be followed for toxicity and outcome (local and systemic recurrence, survival). In addition, patients will complete a self-assessment of QOL at baseline, week 3, day 45-60 and 2-yr follow-ups.

Interventions
Patients will receive 15 daily radiation fractions of 2.7 Gy, Monday to Friday for three weeks, to the entire breast/chest wall and axillary level III and supraclavicular nodes with a daily concomitant boost of 0.5 Gy to the tumor bed, for a total daily dose of 3.2 Gy to the tumor bed (2.7 Gy + 0.5 Gy). The overall dose will be 40.5 Gy to the breast/chest wall, axillary level III and supraclavicular nodes, and 48.0 Gy to the tumor bed.
