An observational study in Breast Cancer, sponsored by Albert Einstein College of Medicine. Recruiting at 1 site in United States. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-22.

This registry trial is designed to track the local control rates and side effects of IORT, which will be implemented for women who are suitable partial breast irradiation (PBI) per the latest American Society of Radiation Oncology (ASTRO) guidelines.
Eligible patients will be referred for radiation oncology consultation by the operating surgeon. Patients will be presented with all radiation options and if they choose IORT, they will be offered enrollment onto the registry trial and consented accordingly. The registry will collect treatment data from the operation, radiation and pathology notes post IORT for each patient enrolled. Sources of research material, i.e. resected breast tissue and lymph nodes, will be obtained as part of routine clinical care. No additional tissue will be collected from patients due to enrollment on this registry trial. No additional studies will be performed outside of the routine standard of care.
Post treatment, the registry will collect data based on the standard of care follow up schedule. Follow-up visits will be scheduled 2-3 weeks post-operatively, as per standard of care, to review the final pathology and for the initial toxicity assessment. Patients found to have positive margins and/or lymph node involvement may require further surgery and/or additional external beam radiation. Additional follow-up visits with radiation oncology will be scheduled at 6 months and 1, 2, 3, 4, and 5 years following IORT. Toxicity will be scored using Common Terminology Criteria for Adverse Events (CTCAE) v4.03. Local control will be evaluated using clinical exam and semi-annual to annual mammograms. All such information will be tracked and recorded into the registry database.
14,825 studies on the registry are indexed under Breast Neoplasms; 3,319 are open to participants now.
This study's planned enrollment of 460 is above the median of 184 across 3,235 observational studies indexed under Breast Neoplasms.

Patients enrolled on this study will be planned for lumpectomy with or without sentinel node biopsy for early stage breast cancer. Patients will be evaluated by a radiation oncologist who specializes in the treatment of breast cancer and will be deemed to be eligible for IORT. Patients with a history of ipsilateral cancer and/or prior in-field radiation are eligible, as IORT would likely be less toxic than repeat whole or partial breast external beam radiation and can allow patients to avoid mastectomy who wish to do so.

Exclusion criteria
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
