Eligibility Criteria
Inclusion
- Only patients recruited into the "Randomized Trial of Hypofractionated Radiotherapy Post-Lumpectomy in Women with Node Negative Breast Cancer" study are eligible to be enrolled into this study.
- The female patient has a histological diagnosis of invasive carcinoma of the breast, and no evidence of metastatic disease.
- Has had a lumpectomy (including segmental resection and partial mastectomy), that is, surgical excision of the tumour with a rim of normal tissue.
- Patient has not had an axillary dissection, OR for patients who have had an axillary dissection, all nodes are negative for metastatic disease.
Exclusion
- Tumour greater than 5 cm in greatest diameter on pathological examination.
- The presence of invasive or intraductal (noninvasive) breast cancer involving the surgical margins.
- Clinical evidence prior to surgery of infiltration of the skin of the involved breast such as edema, ulceration, or fixation of the tumour to underlying muscle, or inflammatory breast cancer.
- Bilateral malignancy of the breast (synchronous or metachronous).
- More than one primary invasive tumour in the same breast.
- Previous surgery for breast cancer.
- Pathological status of axilla is unknown.
- Status for adjuvant systemic therapy not determined.
- For patients not treated with adjuvant chemotherapy: unable to commence radiation therapy within 16 weeks of last surgical procedure on the breast.
- For patients treated with adjuvant chemotherapy: unable to commence radiation therapy within 8 weeks of the last dose of chemotherapy.
- Serious nonmalignant disease (eg. cardiovascular, renal, etc.) which would preclude surgical or radiation treatment.
- Currently pregnant or lactating.
- Breast deemed too large to permit satisfactory radiation (ie. separation \> 25 cm).
- Previous concomitant malignancies of any type except squamous, or basal cell carcinomas of the skin, or carcinoma in situ of the cervix which have been effectively treated.
- Geographic inaccessibility for follow-up.
- Psychiatric or addictive disorders which preclude obtaining informed consent or adherence to the protocol.
