RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether whole-breast radiation therapy is more effective when given with or without additional radiation therapy to the tumor in treating patients with ductal carcinoma in situ.

PURPOSE: This randomized phase III trial is studying breast-conserving surgery followed by whole-breast radiation therapy to see how well it works when given with or without additional radiation therapy to the tumor in treating women with ductal carcinoma in situ.

Primary Outcome Measures:
  • Time to recurrence

Estimated Enrollment: 1950
Study Start Date: November 2008
Estimated Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Arm I
Patients undergo whole breast irradiation (WBI) once daily for 5 weeks (weekdays only).
Radiation: whole breast irradiation
Patients undergo whole breast irradiation
Experimental: Arm II
Patients undergo WBI as in arm I and a radiation tumor bed boost once daily for 8 days (weekdays only).
Radiation: partial breast irradiation
Patients undergo radiation tumor bed boost
Radiation: whole breast irradiation
Patients undergo whole breast irradiation

Detailed Description:



  • Estimate and compare local recurrence-free survival of women with ductal breast carcinoma in situ (DCIS) treated with breast-conserving surgery followed by whole breast irradiation with vs without a radiation tumor bed boost.


  • Compare relapse-free survival between the two arms.
  • Compare overall survival.
  • Compare acute and late toxicities.
  • Compare cosmetic results and quality of life.
  • Identify patients at risk for late toxicities using a biological test.


  • Store blood samples at the CEPH (French Center of the Human Polymorphism Center) for polymorphism analyses.

OUTLINE: This is a multicenter study. All patients undergo breast-conserving surgery (after a single intervention or second excision) with a margin ≥ 1 mm. A superficial or deep margin is acceptable if the surgery has left the skin tissue or the fascia pectoral muscle, respectively. Twelve weeks later, patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients undergo whole breast irradiation (WBI) once daily, 5 days a week for 5 weeks.
  • Arm II: Patients undergo WBI as in arm I. Patients also undergo a radiation tumor bed boost once daily for 8 fractions (weekdays only) over 2 weeks.

Quality of life will be assessed.

After completion of study treatment, patients are followed up every 6 months for 5 years and then annually for 10 years.
