Comparison of Intra-operative Radiotherapy With Post-operative Radiotherapy for Women With Ductal Carcinoma in Situ
A study testing Intraoperative Radiotherapy and Whole breast radiation in people with Breast Neoplasms, run by Liao Ning at 1 site in China.
Trial summary
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 compare the effectiveness of radiation therapy during surgery and whole-breast radiation therapy in… Read more about this study

About this study
Official title: Comparison of the Efficacy of Intra-operative Radiation Therapy After Conserving Surgery With Post-operative Whole Breast Radiotherapy for Women With Ductal Carcinoma in Situ
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 compare the effectiveness of radiation therapy during surgery and whole-breast radiation therapy in treating women who have undergone breast-conversing surgery for Intermediate or high 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 RadiotherapyRadiation
Boost with 20 Gy during BCS, EBRT with 46-50 Gy
Whole breast radiationRadiation
whole breast radiation after BCS with 46-50 Gy
| Study group | Role | What they receive |
|---|---|---|
| Intraoperative Radiotherapy | Experimental | Boost with 20 Gy during BCS, EBRT with 46-50 Gy Receives: Radiation: Intraoperative Radiotherapy |
| whole breast radiation | Active comparator | WRT:whole breast radiation after BCS with 46-50 Gy Receives: Radiation: Whole breast radiation |
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
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
Secondary outcomes (1)
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

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?
ipsilateral breast tumor recurrence rate after surgery within five years (time frame: Within 5 years after surgery). The study lists 2 primary outcomes in all. 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.
