whole breast radiotherapy, tumor bed boost

Brief summary

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.

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.

Interventions

RADIATIONDaily Radiation Therapy

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.

RADIATIONWeekly Radiation Therapy

15 weekly 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.

Score on SF-36 v2 Vitality ScaleBaselineSF-36 is an extensively used questionnaire designed to compare health status across various populations and is commonly used in cancer trials Our survey includes the portion of the SF-36 focused on the assessment of patient fatigue, or vitality, at various stages of treatment Example question: How much of the time during the past 4 weeks did you feel full of life? (Answer on scale 1 to 5). 1 = All of the time; 2 = Most of the time; 3 = Some of the time; 4 = A little of the time; 5 = None of the time.
