Randomisation B:
Arm 1: Whole breast RT alone using standard fractionation
Arm 3: Whole breast RT using standard fractionation plus tumour bed boost  

Or Randomisation C:
Arm 2: Whole breast RT alone using shorter fractionation ;
Arm 4: Whole breast RT using shorter fractionation plus tumour bed boost


To improve the outcome of women with non-low risk DCIS treated with breast conserving therapy.
To evaluate time to local recurrence in women with DCIS treated with breast conserving surgery followed by: whole breast RT alone versus whole breast RT plus tumour bed boost; RT using the standard fractionation schedule versus the shorter schedule.


Primar endpoint:

  • Time to local recurrence

Secondary endpoints:

  • Overall survival
  • Time to disease recurrence
  • Cosmetic outcome
  • Quality of life
  • Toxicity
Main eligibility criteria:
  • DCIS (non-low risk) treated by BCS
  • Clinically node-negative
  • =>18 years
  • Female
