ClinicalTrials.gov Identifier:
NCT02389673
First received: March 10, 2015
Last updated: NA
Last verified: March 2015
History: No changes posted
  Purpose
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.

Condition Intervention
Breast Neoplasms
Device: Intraoperative Radiotherapy

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Intra-operative Radiotherapy After Breast-conversing Surgery in Treating Women With Ductal Carcinoma in Situ Breast Cancer

Further study details as provided by Guangdong Academy of Medical Sciences:

Primary Outcome Measures:
  • ipsilateral breast tumor recurrence rate after surgery within five years [ Time Frame: Within 5 years after surgery ]
    Within 5 years after surgery,we should evaluate ipsilateral breast tumor recurrence and Disease free survival as the most important outcome measure


Secondary Outcome Measures:
  • Disease free survival after surgery within five years [ Time Frame: Within 5 years after surgery ]
    Within 5 years after adjuvant chemotherapy,we should evaluateDisease free survival(DFS) rates as thet important outcome measure.

  • Overall survival after surgery within ten years [ Time Frame: Within ten years after surgery ]
    After surgery,we should evaluate overall survival (OR)rates as the secondary important outcome measure.


Estimated Enrollment: 222
Study Start Date: October 2014
Estimated Study Completion Date: June 2026
Estimated Primary Completion Date: June 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Without Radiotherapy
Patients just accept breast-conversing surgery without radiotherapy.
Experimental: Intraoperative Radiotherapy
Boost with 20 Gy during BCS, EBRT with 46-50 Gy
Device: Intraoperative Radiotherapy
Boost with 20 Gy during BCS, EBRT with 46-50 Gy
