Intensity Modulated Radiotherapy (IMRT) vs. 3D-conformal Accelerated Partial Breast Irradiation (APBI) for Early Stage Breast Cancer After Lumpectomy
United States660 participantsStarted 2009-07
Plain-language summary
In the setting of radiotherapy as part of breast-conservation therapy for patients with early stage breast cancer, the novel planning and delivery method of intensity modulated radiotherapy is an effective and safe alternative to the commonly-used standard 3D-conformal external beam radiotherapy, spares more normal breast and lung tissue, and may lead to improved clinical outcomes.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Histologically confirmed disease (AJC Classification): Tis, T1, T2 (≤ 3.0 cm), N0, M0.
* Microscopic multifocal disease is only allowed when the entire span of identified disease measures 3.0 cm or less.
* Negative surgical margins ( ≥ 0.2 cm) after final surgery.
* Subjects with infiltrating lobular histologies or high nuclear grade DCIS will be required to have breast MRI scanning as part of the initial staging to verify localized disease.
* Subjects with DCIS will be included in the study only if they had an MRI prior to lumpectomy.
* Findings on MRI scanning revealing relevant suspicion of disease outside of planned lumpectomy volume should be further evaluated by ultrasound and, if necessary biopsy, to exclude multicentric/multifocal disease.
* Subjects with malignant calcifications on mammography will be required to have repeat mammography after surgery to ensure removal of all malignant calcifications.
* Willing to complete additional screening requirements and meet eligibility criteria as defined in protocol Sec. 4.4.
* Successful placement of fiducial markers for IGRT requiring nonmigrating fiducials.
* PTV to ipsilateral breast ratio (IBR) ≤ 25 %.
* Radiotherapy anticipated to begin within 10 weeks of lumpectomy or re-excision of margins.
Exclusion Criteria:
* Pregnancy or breast-feeding.
* Have collagen-vascular disease.
* Inadequate surgical margins ( \< 0.2 cm) after final surgery.
* Subjects with persistent malignant/suspicious micro-cal…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
