Repeat Breast Conserving Surgery Followed by Daily Partial Breast Irradiation in Ipsilateral Breast
What this study is about
The standard treatment for participants whose cancer has returned after breast conserving surgery is radiation given twice daily (separated by at least 6 hours) for a total of 30 treatments. The purpose of this study is to find out if giving radiation once a day for 15 treatments after repeat breast conserving surgery works as well as giving it the standard way.

Interventions
RADIATION
Radiation Therapy
Weeks 1, 2 and 3 * Weeks 1, 2 and 3 will include 5 days of treatment. * One radiation treatment to breast on each of the 5 days. Each radiation treatment session will last a 30 minutes.
Primary outcome measures
Treatment-related adverse events as graded by CTCAE criteria
Time frame: 1 year from the completion of re-irradiation
Rate of grade 3+ treatment-related skin, fibrosis, and breast pain adverse events occurring within 1 year from the completion of re-irradiation as graded by CTCAE criteria.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Participants' recurrences must have histologically confirmed ductal carcinoma in-situ, invasive ductal, medullary, papillary, colloid (mucinous), tubular or mixed histologies.
- Lesion size \< 3 cm treated with a partial mastectomy. Participants with invasive cancer and clinically and radiographically negative axillas do not require an axillary lymph node sampling unless they did not have prior axillary lymph node sampling (e.g. previous cancer was DCIS). Patients with DCIS as their recurrence do not require surgical assessment of the axilla. Repeat sentinel lymph node biopsy is permitted.
- Negative resection margins with at least a no tumor on ink or a negative re-excision.
- Hormonal therapy is allowed. If chemotherapy is planned, it can be delivered either prior or after the radiation is delivered. There must be at least 2 weeks between radiation and chemotherapy. HER2 directed therapy can be delivered concurrently with radiation.
- Participants must be \> 18
Where
- Cleveland, Ohio

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
