Prognostic Study of Sentinel Lymph Node and Bone Marrow Metastases in Women With Stage I or Stage IIA Breast Cancer
RATIONALE: Biopsy of sentinel lymph nodes and bone marrow may improve the ability to detect and determine the extent of cancer.
PURPOSE: Phase III prognostic study of sentinel lymph node metastases and bone marrow metastases in women who have stage I or stage IIA breast cancer.

Experimental: Surgery + radiotherapy + adjuvant therapy
Patients undergo bilateral anterior iliac crest bone marrow aspiration to test for presence of micrometastases. Patients then undergo breast-conserving therapy comprising segmental mastectomy and sentinel lymph node dissection (SLND) with planned postoperative whole-breast radiotherapy and systemic adjuvant therapy. The SLND comprises ipsilateral axillary sentinel node identification and histopathology.
Patients with no sentinel node identified intraoperatively and patients with sentinel node metastasis identified by hematoxylin and eosin (H&E) who choose not to be registered to ACOSOG-Z0011 undergo axillary lymph node dissection involving removal of at least level I and II nodes.
All patients undergo whole-breast radiotherapy (excluding a supraclavicular field) 5 days a week for a maximum of 8 weeks.
Patients are followed at 30 days; at 6, 12, 18, 24, 30, and 36 months; and then annually until 10 years after surgery.

- Estimate the prevalence and evaluate the prognostic significance of sentinel lymph node micrometastases detected by immunohistochemistry in women with stage I or IIA breast cancer.
- Estimate the prevalence and evaluate the prognostic significance of bone marrow micrometastases detected by immunocytochemistry in these patients.
- Evaluate the hazard rate for regional recurrence in women whose sentinel nodes are negative by hematoxylin and eosin (H&E) staining.
- Provide a mechanism for identifying women whose sentinel nodes contain metastases detected by H&E so that these women can be considered as candidates for ACOSOG-Z0011.
