  Purpose
The purpose of this trial is to investigate the difference in late radiation morbidity between partial breast irradiation and whole breast irradiation given to women operated on with breast conservation surgery for early breast cancer with a low risk of local recurrence.

Condition Intervention
Breast Carcinoma Radiation: Partial breast irradiation Radiation: Whole breast irradiation

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Partial Breast Versus Whole Breast Irradiation to Women ≥ 60 Years Operated With Breast Conservation for Early Breast Cancer: a Randomized Fase II Trial

Primary Outcome Measures:
  • Grade 2 and/or 3 fibrosis after radiotherapy [ Time Frame: 3 years ]

Secondary Outcome Measures:
  • Any other late morbidity after adjuvant radiotherapy, genetic risk profile for late morbidity, recurrence/survival [ Time Frame: 10 years ]
    morbidity and recurrences


Enrollment: 882
Study Start Date: May 2009
Estimated Study Completion Date: March 2026
Primary Completion Date: March 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Partial breast irradiation
40 Gy/15 fractions, 3 weeks
Radiation: Partial breast irradiation
40 Gy/15 fractions, 3 weeks
Active Comparator: Whole breast irradiation
40 Gy/15 fractions, 3 weeks
Radiation: Whole breast irradiation
40 Gy/15 fractions, 3 weeks

Detailed Description:

The study is 2-armed. In both treatment arms the radiotherapy consists of 40 Gy in 15 fractions, 2.67 Gy per fraction. The primary endpoint in the trial is late radiation morbidity evaluated as fibrosis, secondary endpoints are other types of late morbidity, rate of local recurrence and an attempt to establish a genetic risk profile for development of late radiation morbidity.

The hypothesis is that women operated with breast conservation for a breast carcinoma with low risk of local recurrence can be offered partial breast irradiation without risking more late radiation morbidity compared to whole breast irradiation.
