About this study
Official title: Intra-Operative Radiotherapy After Breast Conserving Therapy in the Treatment of in Situ and Early Stage Breast Cancer
Single arm study to assess the effectiveness of single dose intraoperative radiation therapy in patient with in situ and early stage breast cancer.
Read the detailed description
The purpose of this clinical study is to assess the effectiveness of IORT, using an electronic brachytherapy system, in patients with limited-volume in situ and early stage breast cancer, with endpoints of:
- Local recurrence in early stage breast cancer patients treated with IORT.
- Toxicity associated with IORT.
- Long-term disease-specific and overall survival
- Cosmetic results using the Harvard Scale at start and follow-up periods in patients treated with IORT.
- Quality of life in patients treated with IORT.
- Health care costs associated with IORT.
- Conditions
- Breast Cancer
- Being tested
- Intraoperative Radiation Therapy
- Keywords
- IORT, Breast Cancer
- Medical subject headings
- Breast Neoplasms
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intraoperative Radiation TherapyRadiation
Also called IORT
Intraoperative radiation therapy at the time of partial mastectomy in early stage breast cancer
| Study group | Role | What they receive |
|---|---|---|
| Treatment | Other | Patients treated with intraoperative radiation therapy at the time of partial mastectomy. Receives: Radiation: Intraoperative Radiation Therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Local Disease Relapse
Patients are evaluated clinically at 3 months, 6 months, 9 months, 1 year and every six months for 10 years for disease recurrence. In addition to clinical exams, yearly mammograms and other imaging studies as deemed appropriate will be obtained to rule out recurrent disease. Recurrent disease will be defined as cancer recurrence within 2cm of site of original tumor bed (marked by surgical clips).
Measured: 10 years
Secondary outcomes (1)
Disease specific and overall survival
Disease specific and overall survival will be obtained for all patients in the study.
Measured: 10 years

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Local Disease Relapse (time frame: 10 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
