  Purpose

The standard treatment for women with invasive breast cancer is local excision follow by whole breast radiation. The local recurrence rates are low, side effects are low, and the cosmetic outcome is excellent. The treatments, however, need to be given daily for 5 1/2 to 6 1/2 weeks, making the treatment difficult, particularly for the elderly and for women who need to travel long distances for the therapy. The goal of this study is to determine the toxicity and efficacy of giving the radiation in a shorter time, using higher daily doses of radiation.

The risk of recurrence in the elderly population is lower, and since majority of recurrences occur close to the area where the tumor previously was, it is hypothesized that radiation to that area of the breast would be sufficient to obtain low risk of recurrence. When a smaller volume of tissue is treated, more radiation can be given daily, and therefore the treatment can be shortened. The risk of side effects increases as the dose per daily treatment increases. Therefore, the goal is to study the short term side effects, long term side effects, and cosmetic outcome of daily radiation using higher daily doses for shorter period of time. We will also follow the recurrence rate. Because less of the breast tissue will be treated, there may be a small increased risk of recurrence. Because the higher fraction size can result in more side effects we will be using intensity modulated radiation (IMRT). IMRT is the most advanced individually tailored radiation treatment technique that results in the least amount of side effects. It allows tight monitoring of the dose in the untreated breast.

Seventy five women diagnosed with stage I breast cancer will participate. Participants must have a lumpectomy, clear margins and no lymphovascular invasion to be eligible. A treatment planning CT scan will be obtained. If the lumpectomy cavity can be clearly delineated, an IMRT plan will be generated with predefined strict dose requirement criteria. The patients will be treated once daily, 5 days a week, for a total of 10 treatments (instead of standard 28-33). The patients will be evaluated for toxicity weekly during the treatment, and weekly for additional 4 weeks. At each of these evaluations, they will fill out a short 10 minute questionnaire detailing their side effects. Follow-up will continue every 3 months for 3 years, and every 6 months for 2 more years. At each of these follow-ups a short questionnaire will be filled out by the patients detailing any toxicity, as well as their perception of the cosmetic outcome. A cosmesis questionnaire will be also be filled out by the evaluating physician before radiation, at 6, 12, 18, and 24 months, and yearly for 3 more years. A total of 5 years of follow-up is planned. Participants will also have the option of consenting to the photograph portion of the study. Those who do will have photographs taken of their breasts (excluding faces) at the time they complete the cosmetic questionnaire, to evaluate the cosmetic outcome.
