About this study
Official title: Intra-operative Radiotherapy After Breast-conversing Surgery in Treating Women With Ductal Carcinoma in Situ Breast Cancer
Whether the patients with low grade ductal carcinoma in situ breast cancer should accept radiationtherapy is uncertain.Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation during surgery followed by external-beam radiation to the entire breast may kill more tumor cells.The clinical trial is conducting to find out the effectiveness of radiation therapy during surgery in treating women who have undergone breast-conversing surgery for low grade ductal carcinoma in situ breast cancer.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intraoperative RadiotherapyDevice
Boost with 20 Gy during BCS, EBRT with 46-50 Gy
| Study group | Role | What they receive |
|---|---|---|
| Without Radiotherapy | No intervention | Patients just accept breast-conversing surgery without radiotherapy. |
| Intraoperative Radiotherapy | Experimental | Boost with 20 Gy during BCS, EBRT with 46-50 Gy Receives: Device: Intraoperative Radiotherapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
ipsilateral breast tumor recurrence rate after surgery within five years
Within 5 years after surgery,we should evaluate ipsilateral breast tumor recurrence and Disease free survival as the most important outcome measure
Measured: Within 5 years after surgery
Secondary outcomes (2)
Disease free survival after surgery within five years
Within 5 years after adjuvant chemotherapy,we should evaluateDisease free survival(DFS) rates as thet important outcome measure.
Measured: Within 5 years after surgery
Overall survival after surgery within ten years
After surgery,we should evaluate overall survival (OR)rates as the secondary important outcome measure.
Measured: Within ten years after surgery

Contact Liao Ning, MD,PhD (+86 83827812), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
ipsilateral breast tumor recurrence rate after surgery within five years (time frame: Within 5 years after surgery). 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?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
