Data quality was ensured by review of data by the Alliance Statistics and Data Center and by the study chairperson following Alliance policies.

Patients were randomized to either completion ALND with a minimum of 10 nodes, or to observation. Thus, although nodal irradiation may be added to the management of some acpsog with node-positive tumors based on an evaluation of their overall risk profile, the routine use of nodal irradiation for all patients with 1 or 2 sentinel node metastases managed with SLND alone may not be justified.

Internal mammary and medial supraclavicular irradiation in breast cancer. This study has several limitations. Longer follow-up was necessary because the majority of the patients had estrogen receptor-positive tumors that may recur later in the disease course the ACOSOG is now part of the Alliance for Clinical Trials in Oncology.

Due to the significant morbidity of ALND, including paresthesias, lymphedema, seroma, and infection, judicious use of the procedure is important. However, these conclusions apply only to patients meeting ACOSOG Z eligibility criteria and should not be extrapolated to the management of patients with positive palpable nodes, those with metastases in more than 2 sentinel nodes, patients forgoing whole-breast irradiation, those treated with mastectomy without radiation, or patients receiving neoadjuvant therapy because all of these are circumstances in which the elimination of ALND is not known to be safe.

Please review our privacy policy. The ongoing Positive Sentinel Node-Adjuvant Therapy Alone vs Adjuvant Therapy Plus Clearance or Axillary Radiotherapy trial for women with metastases in 1 or 2 sentinel nodes treated with breast-conserving surgery or mastectomy will provide important acoso about the safety of omitting ALND after mastectomy, but this study is not expected to complete accrual until All secondary analyses were tested for differences.

Potential impact of application of Z derived criteria to omit axillary lymph node dissection in node positive breast cancer patients. This confirms that although distant recurrence among hormone receptor—positive tumors is a later event, nodal recurrence among these patients is primarily an early acoog.

Axillary lymph node dissection ALNDlong tgial to identify women with axillary nodal metastases, was replaced as a staging procedure by the less morbid sentinel lymph node dissection SLND. Breast cancer, particularly hormone receptor—positive breast cancer, is a disease with a long natural history 1112 and a substantial risk of locoregional and systemic relapses occurring after 5 years.

However, the analysis of overall survival after the completion of study follow-up was not prespecified.

Disease-free survival, which was defined as the time from randomization to death or first breast cancer recurrence, was a secondary end point hrial with morbidity and locoregional recurrence. The secondary outcome was disease-free survival.

Add to My Bibliography. At a median follow-up of 9. Among T breast cancer patients with a positive sentinel lymph node biopsy undergoing lumpectomy and whole-breast radiation, does axillary lymph node dissection improve survival or local control compared to nodal observation? The Journal of the American Medical Association. Sentinel lymph node biopsy is a commonly used method of detecting micrometastatic axillary disease at initial presentation.


Ten-year follow-up was consistent with the 5-year published results. Low-dose oral cyclophosphamide and methotrexate maintenance for hormone receptor-negative early breast cancer: Eligible patients were women with clinical T1 or T2 invasive breast cancer, no palpable z0011 adenopathy, and 1 or 2 sentinel lymph nodes containing metastases.

Design, Setting, and Participants: A population-based study of the effects of a regional guideline for completion axillary lymph node dissection on axillary surgery in patients with breast cancer. In addition, some patients had irradiation protocol variations that could have resulted in a small alteration of outcomes; however, these patients were distributed similarly in both study groups.
