Brief Summary:
The purpose of this study is to compare the effects on low risk breast cancer receiving usual care that includes regional radiation therapy, with receiving no regional radiation therapy. Researchers want to see if not giving this type of radiation treatment works as well at preventing breast cancer from coming back.

Condition or disease Intervention/treatment Phase
Breast Cancer Radiation: Radiation Other: No Radiation Phase 3

Detailed Description:
Women with node positive breast cancer normally will receive endocrine therapy and some may receive chemotherapy to help prevent the cancer from coming back. Many women will also receive radiotherapy to the whole breast/chest area and the surrounding lymph glands (called regional radiotherapy). No one really knows whether patients with low risk breast cancer need to receive regional radiotherapy. Some women may be getting regional radiotherapy who do not need it. These women may be exposed to the side effects of their treatment without benefit.

Primary Outcome Measures :
  1. compare the breast cancer recurrence-free interval (BCRFI) between patients that received regional RT or not [ Time Frame: 9.5 years ]
    Defined as time from randomization to time of invasive recurrent disease in the ipsilateral chestwall, breast, regional nodes, distant sites or death due to BC.


Secondary Outcome Measures :
  1. Compare the invasive disease-free survival between patients that received regional RT or not. [ Time Frame: 9.5 years ]
    Defined as time from randomization to time of invasive recurrent disease in the ipsilateral chestwall, breast, regional nodes, distant sites or death due to BC

  2. Compare the breast cancer mortality between patients that received regional RT or not. [ Time Frame: 9.5 years ]
    Defined as death due to BC

  3. Compare the overall survival (OS) between patients that received regional RT or not [ Time Frame: 9.5 years ]
    Defined as the time from randomization to the time of death from any cause

  4. Compare the locoregional recurrence-free interval (LRRFI) between patients that received regional RT or not. [ Time Frame: 9.5 years ]
    Defined as time from randomization to time of invasive recurrent disease in the ipsilateral chestwall, breast or regional nodes, or death to due to BC

  5. Compare the distant recurrence-free interval (DRFI) between patients that received regional RT or not. [ Time Frame: 9.5 years ]
    Defined as time from randomization to time of invasive recurrent disease in distant sites or death due to BC

  6. Number and severity of adverse events using the current CTCAE version 4 [ Time Frame: 9.5 years ]
  7. Compare arm volume and mobility measurements between patients that received regional RT or not [ Time Frame: 9.5 years ]
    A Fisher's Exact Test will be used to compare lymphedema and arm abduction deficit between two arms. Defined as a difference in arm abduction of 10% or greater in the comparison of the ipsilateral to the contralateral arm.

  8. Compare patient-reported outcomes (PROs) and the quality of life (QOL) between patients that received regional RT or not [ Time Frame: 9.5 years ]
    using the NSABP Questionnaire for patients treated by BCS or mastectomy.

  9. Compare the quality of life (QOL) between patients that received regional RT or not [ Time Frame: 9.5 years ]
    Overall QOL (EORTC QLQ-C30) will be compared between the two treatment groups using a similar approach.

  10. Compare the cost-effectiveness between patients that received regional RT or not [ Time Frame: 9.5 years ]
    Costs will be expressed in $US and $CAN base currencies based on the final year of the study. An average cost per study subject by treatment arm for an overall mean cost per study arm will be generated

  11. Compare the quality of life (QOL) between patients that received regional RT or not [ Time Frame: 9.5 years ]
    breast symptoms (NSABP B32 Questionnaire) will be compared between the two treatment groups using a similar approach.

  12. Compare the quality of life (QOL) between patients that received regional RT or not [ Time Frame: 9.5 years ]
    skin symptoms and fatigue (EORTC QLQ-BR23) will be compared between the two treatment groups using a similar approach.

Criteria

Inclusion Criteria:

  • Patients must be women with newly diagnosed histologically proven invasive carcinoma of the breast with no evidence of metastases, staged as per site standard of care.
  • Patients must have been treated by BCS or mastectomy with clear margins of excision. Post-mastectomy positive margins for invasive disease and/or DCIS is not allowed. Multifocal disease (i.e. the presence of two or more foci or breast cancer within the same breast quadrant) and multicentric disease (i.e. the presence of two or more foci of breast cancer in different quadrants of the same breast) are allowed.
  • Patients with T3N0 disease are eligible.
  • Patients with disease limited to nodal micrometastases are eligible
  • Patients with nodal macrometastases (>2mm) treated by axillary dissection must have 1-3 positive axillary nodes (macrometastases, > 2 mm).
  • Patients treated by mastectomy and SLNB alone must have only 1-2 positive axillary nodes (macrometastases, > 2 mm).
  • Patients must be ER ≥ 1% and HER2 negative on local testing
  • Patients must have an Oncotype DX recurrence score ≤25 obtained from testing of breast tumour tissue from a core biopsy or from the surgical specimen.
  • Patient must consent to provision of, and investigator(s) must agree to submit to the CCTG Central Tumour Bank, a representative formalin fixed paraffin block of tumour tissue in order that the specific correlative marker assays described in the protocol may be conducted
  • Patient must consent to provision of samples of blood in order that the specific correlative marker assays described in the protocol may be conducted.
  • Patients must have had endocrine therapy initiated or planned for ≥ 5 years. Premenopausal women will receive ovarian ablation plus aromatase inhibitor therapy or tamoxifen if adjuvant chemotherapy was not administered. For all patients, endocrine therapy can be given concurrently or following RT.
