Balloon Brachytherapy and External Beam Irradiation for Breast Cancer
(APBI Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines the effectiveness of balloon brachytherapy, a type of internal radiation therapy, for individuals with early-stage breast cancer. The researchers aim to determine the frequency of cancer recurrence and assess the treatment's impact on appearance and daily life over ten years. Participants will receive radiation that targets only part of the breast, with their health closely monitored. Women who have undergone a lumpectomy for stage 0 or 1 breast cancer, with tumors no larger than 2-3 cm and no previous major breast cancer treatments, may be suitable candidates for this trial. As an unphased trial, this study offers participants the chance to contribute to groundbreaking research that could shape future breast cancer treatments.
Do I need to stop taking my current medications to join the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are on hormonal therapy, it must stop at or before study entry and can resume after chemotherapy if applicable. Also, any current therapy with hormonal agents like raloxifene or tamoxifen must be discontinued before joining the study.
What prior data suggests that balloon brachytherapy and 3D conformal external beam irradiation are safe for breast cancer treatment?
Research has shown that balloon brachytherapy is generally safe, though it carries some risks. One study found that about 20.4% of women undergoing this treatment experienced wound healing problems. In contrast, 12.7% of women receiving whole breast irradiation (WBI) faced similar issues.
For 3D conformal external beam irradiation, studies have shown encouraging results. Research found that patients experienced fewer short-term side effects and better cosmetic outcomes compared to WBI. Specifically, they had fewer noticeable changes in breast appearance and felt less discomfort during treatment.
Overall, both treatments are generally well-tolerated, with manageable side effects. Discussing these risks with a doctor is important to understand their implications.12345Why are researchers excited about this trial?
Balloon brachytherapy is unique because it offers a more targeted form of radiation treatment for breast cancer. Unlike traditional radiation therapy, which can affect a larger area, balloon brachytherapy focuses the radiation precisely on the area where cancer was removed. This method has the potential to minimize exposure to healthy tissues and reduce side effects. Researchers are excited about this treatment because it may allow for a shorter treatment duration and could improve the quality of life for patients by reducing the overall burden of therapy.
What evidence suggests that balloon brachytherapy and 3D conformal external beam irradiation could be effective for breast cancer?
Research has shown that balloon brachytherapy, such as the MammoSite device, effectively treats early-stage breast cancer. Studies indicate that it delivers radiation directly to the tumor area, providing excellent local control. Five-year results suggest high survival rates, with breast cancer-specific survival nearly 100%. In this trial, participants will receive partial breast irradiation using either balloon brachytherapy or 3D conformal external beam irradiation. Evidence shows that 3D conformal external beam irradiation effectively reduces the chance of cancer returning in the treated area. Both treatments generally result in good cosmetic outcomes, preserving the breast's appearance.56789

Are You a Good Fit for This Trial?
This trial is for women over 50 or postmenopausal with stage 0 or 1 breast cancer, having a single tumor ≤2-3 cm based on type. They must have had a lumpectomy with clear margins and no prior treatments for the current cancer except limited hormonal therapy. Men, pregnant/lactating women, those with certain previous cancers or conditions like collagen vascular disease are excluded.Inclusion Criteria
