Partial Radiation for Breast Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new approach called Accelerated Partial Breast Irradiation (APBI) to treat breast cancer by administering radiation before surgery. Researchers aim to assess the safety of this method by examining wound healing, cosmetic results, and any side effects. They also study the cancer's response to this treatment at the tissue level. This trial may suit individuals with small, non-spreading breast cancer (tumor size ≤ 2cm) that is estrogen-receptor positive. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this innovative approach.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this radiation protocol is safe for breast cancer patients?
Research has shown that Accelerated Partial Breast Irradiation (APBI) is generally safe for treating breast cancer. Studies have found that APBI causes fewer long-term side effects compared to whole breast treatment, resulting in less lasting damage to healthy tissues. APBI also improves the appearance of the treated area, making it resemble normal breast tissue more closely after treatment. Another study found that APBI has fewer harmful effects and is easier for patients to manage. However, one study noted that some individuals experienced moderate issues with soft tissue and bone later on. Overall, evidence suggests that APBI is well-tolerated, with manageable side effects for most patients.12345
Why do researchers think this study treatment might be promising?
Accelerated Partial Breast Irradiation (APBI) is unique because it targets only the part of the breast where the cancer is located, rather than the whole breast. Unlike traditional whole-breast irradiation, which can take several weeks, APBI can be completed in just a few days with five treatment sessions. Researchers are excited about this approach because it could potentially reduce treatment time and minimize radiation exposure to healthy tissues, leading to fewer side effects and a quicker recovery for patients.
What evidence suggests that Accelerated Partial Breast Irradiation (APBI) might be an effective treatment for breast cancer?
Research has shown that Accelerated Partial Breast Irradiation (APBI), which participants in this trial will receive preoperatively, can effectively treat breast cancer. Studies have found that APBI provides similar long-term results to whole-breast radiotherapy. Specifically, the breast cancer-specific survival rate is very high, about 99.6%, with APBI. Additionally, APBI has similar rates of patients remaining disease-free compared to traditional treatments, with about 84.89% over ten years. Although APBI carries a slightly higher chance of cancer returning in the same area, the likelihood of cancer spreading to other parts of the body remains the same as with standard treatment. Overall, APBI appears to be a promising option for treating breast cancer.56789
Are You a Good Fit for This Trial?
This trial is for breast cancer patients with conditions like Ductal Carcinoma In Situ. Participants should be eligible for surgery and have not received prior radiation therapy or chemotherapy for their breast cancer.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Accelerated Partial Breast Irradiation (APBI)
Trial Overview
The study tests preoperative partial breast radiation (APBI) to see if it's feasible before surgery. It looks at wound healing, cosmetic results, late side effects, and changes in the tumor due to the treatment.

Experimental Treatment
Patients will receive 5 fractions of accelerated partial breast irradiation (APBI) delivered before surgery. Surgery is scheduled 1-3 weeks after radiation. If surgical pathology indicates, additional whole-breast or lymph node radiation may be given postoperatively (3-8 weeks after surgery).
