Trial Information

Intraoperative Radiotherapy (IORT) for the Management of Carcinoma of the Breast: Use of Mammography, Ultrasonography,and Contrast-Enhanced Magnetic Resonance Imaging (CE-MRI) to Identify Candidates for IORT


Patients will be deemed eligible for immediate IORT if the invasive cancer lesion is
estimated to measure ≤ 3.0 centimeters maximum dimension by mammogram, ultrasound, and
CE-MRI and is thought to be resectable with WLE and clear surgical margins, with clinically
staged N0M0 disease, minimum age of 48, and histology of invasive ductal or lobular
carcinoma of the breast. The lesion size determined by imaging will be compared with lesion
size and surgical margin status obtained from the surgical pathology specimen to evaluate
the ability of mammography combined with ultrasound and CE-MRI to identify suitable
candidates for immediate IORT.


Inclusion Criteria:



1. Informed Consent. Each eligible patient must willingly give written consent after
being informed of the procedures to be followed, the experimental nature of the
therapy, alternatives, potential benefits, side effects, risks, and discomforts.

2. Histology. Patients must have biopsy-proven invasive ductal or lobular carcinoma of
the breast.

3. Female, age ≥ 48 years.

4. Clinically and/or histologically negative axillary lymph nodes.

5. No imaging or clinical findings that indicate metastatic disease.

6. Procedure deemed appropriate based upon factors such as breast size by the treating
surgeon and radiation oncologist.

Exclusion Criteria:

1. Male sex

2. Age < 48

3. Non-epithelial breast malignancies such as sarcoma, lymphoma, or metastatic breast
cancer

4. Pregnancy or lactation

5. Serious psychiatric or addictive disorders

6. More than one obvious cancer in the same breast as diagnosed by clinical examination,
mammography, ultrasonography, and/or CE-MRI.

7. Bilateral breast cancer at the time of diagnosis, unless agreed upon by the surgeon
and radiation oncologist.

8. Ipsilateral breast with a previous cancer and/or irradiation.

9. Extensive Intraductal Component (DCIS ≥ 25% of the tumor).

10. Patients presenting with gross nodal disease considered to be clinically malignant by
scanning or proven cytologically or by sentinel node biopsy will be cancelled.

11. Previous history of malignant disease does not preclude entry if the expectation of
relapse-free survival at 10 years is 90% or greater.

12. Lymphovascular invasion on needle biopsy.

13. Patients undergoing primary medical treatment (hormones or chemotherapy) as initial
treatment with intent to reduce tumor size.
