  Purpose

All patients (with Stages 0-II breast cancer) will receive an accelerated three week regimen of prone whole breast radiotherapy. The study intends to test the hypothesis that a weekly boost to the tumor bed, delivered on Friday, before the weekend break, is as well tolerated as the daily boost during accelerated prone radiotherapy.

Primary Outcome Measures:
  • Acute radiation toxicities recorded according to RTOG [ Time Frame: Day 1 of radiation treatment to day 60 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • QOL (Quality of Life) questionnaire of patients on the 2 different arms of treatment [ Time Frame: at baseline, at the end of last week of treatment, and at 2 year Follow-up ] [ Designated as safety issue: No ]
  • Late radiation toxicities recorded according to LENT/SOMA [ Time Frame: yearly for five years after completion of treatment ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 400

Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: ARM 1 daily boost
Radiation Therapy
Radiation: Radiation Therapy

Arm 1= 15 daily radiation fractions of 2.7 Gy, Monday to Friday for 3 weeks, to the whole breast 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 (2.7Gy+0.5 Gy). The overall dose will be 40.5 Gy to the breast and 48.0 Gy to the tumor bed.

Arm 2= 15 daily radiation fractions of 2.7 Gy Monday to friday for three weeks to the entire breast with a Friday boost of 2.0 Gy to the tumor bed, for a total dose to the tumor bed on each friday of 4.7 Gy (2.7 Gy+ 2.0 Gy). The overall dose will be 40.5 Gy to the breast and 46.5 gy to the tumor bed.

Active Comparator: ARM 2 weekly boost

Radiation: Radiation Therapy

Arm 1= 15 daily radiation fractions of 2.7 Gy, Monday to Friday for 3 weeks, to the whole breast 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 (2.7Gy+0.5 Gy). The overall dose will be 40.5 Gy to the breast and 48.0 Gy to the tumor bed.

Arm 2= 15 daily radiation fractions of 2.7 Gy Monday to friday for three weeks to the entire breast with a Friday boost of 2.0 Gy to the tumor bed, for a total dose to the tumor bed on each friday of 4.7 Gy (2.7 Gy+ 2.0 Gy). The overall dose will be 40.5 Gy to the breast and 46.5 gy to the tumor bed.


Detailed Description:

Arm 1 is a concomitant boost protocol over three weeks which has previously been evaluated in over 500 patients (NYU 03-30 and NYU 05-181) and has shown excellent tolerance, and results. Arm 2 evaluates a Weekend Boost Dose (WBD) regimen which may have a radiobiological advantage by counteracting tumor repopulation which can occur over the weekend break. At the time of registration in the study, patients will be randomized to either treatment arm and stratified according to pre or post-menopausal status and on previous chemotherapy received or not.
