Purpose

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.

  • Patients must have had endocrine therapy initiated or planned for ≥ 5 years. Endocrine therapy can be given concurrently or following RT.
  • Patients may or may not have had adjuvant chemotherapy.
  • RT must be administered within 12 weeks of definitive surgery if the patient is not treated with chemotherapy. If adjuvant chemotherapy is given, RT must begin within 2-8 weeks after the last dose.
  • Patient's ECOG performance status must be 0, 1 or 2.
  • Patient's age must be ≥ 40 years.

Exclusion Criteria

  • Patients with nodal disease limited to micrometastases (pN1Mi, > 0.2 mm and ≤ 2 mm) or isolated tumour cells (pN0i+ < 0.2 mm).
  • Any prior history, not including the index cancer, of ipsilateral invasive breast cancer or ipsilateral DCIS treated with radiation therapy. (Patients with synchronous or previous ipsilateral LCIS are eligible.)
  • Synchronous or previous contralateral invasive breast cancer. (Patients with contralateral DCIS not treated with radiation are eligible.)
  • History of non-breast malignancies except adequately treated non-melanoma skin cancers, in situ cancers treated by local excision or other cancers curatively treated with no evidence of disease for ≥ 5 years.

  • Patients who are pregnant.
  • Patients that have had prior ipsilateral chestwall/thoracic radiation.
  • Patients treated with neoadjuvant chemo or endocrine therapy for breast cancer.
  • Patients with serious non-malignant disease (e.g. cardiovascular, scleroderma etc.) which would preclude RT.

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.
