Z0011 Trial

Abstract Background To evaluate the number of patients with early-stage breast cancer, undergoing axillary lymph node dissection for metastatic sentinel lymph nodes, who could benefit from the omission of axillary surgery following the application of ACOSOG Z0011 trial criteria. Methods A retrospective cohort study conducted in the Women’s Hospital of the State University of Campinas. The study population included 384 women diagnosed with early-stage invasive breast cancer, clinically negative axilla, treated with breast-conserving surgery and sentinel lymph node biopsy, radiation therapy, chemotherapy and/or endocrine therapy, from January 2005 to December 2010. ACOSOG Z0011 trial criteria were applied to this population and statistical analysis was carried out to make a comparison between populations. Results A total of 384 patients underwent breast-conserving surgery and sentinel lymph node biopsy. Of the total number of patients, 86 women underwent axillary lymph node dissection for metastatic sentinel lymph nodes. One patient underwent axillary node dissection due to a suspicious SLN intra-operatively. Among these patients, 82/87 (94.3%) had one to two involved sentinel lymph nodes and met criteria for the ACOSOG Z0011 trial with the omission of axillary lymph node dissection. Among the 82 eligible women, there were only 13 cases (15.9%) of lymphovascular invasion and 62 cases (75.6%) of tumors measuring up to 2cm in diameter (T1). Conclusions When eligibility for ACOSOG Z0011 trial criteria was retrospectively exported to our study population, 94.3% of the patients with one to two positive sentinel lymph nodes would benefit from the omission of axillary lymph node dissection. The high rate in our study may be explained by the large number of patients with tumors up to 2.0 cm in size and the small rate of lymphovascular invasion, which are indicative of a favorable prognosis.

Node Dissection

Context.—Sentinel lymph node biopsy has been established as the new standard of care for axillary staging in most patients with invasive breast carcinoma. Historically, all patients with a positive sentinel lymph node biopsy result underwent axillary lymph node dissection. Recent trials show that axillary lymph node dissection can be safely omitted in women with clinically node negative, T1 or T2 invasive breast cancer treated with breast-conserving surgery and whole-breast radiotherapy. This change in practice also has implications on the pathologic examination and reporting of sentinel lymph nodes.Objective.—To review recent clinical and pathologic studies of sentinel lymph nodes and explore how these findings influence the pathologic evaluation of sentinel lymph nodes.Data Sources.—Sources were published articles from peer-reviewed journals in PubMed (US National Library of Medicine) and published guidelines from the American Joint Committee on Cancer, the Union for International Cancer Control, the American Society of Clinical Oncology, and the National Comprehensive Cancer Network.Conclusions.—The main goal of sentinel lymph node examination should be to detect all macrometastases (>2 mm). Grossly sectioning sentinel lymph nodes at 2-mm intervals and evaluation of one hematoxylin-eosin–stained section from each block is the preferred method of pathologic evaluation. Axillary lymph node dissection can be safely omitted in clinically node-negative patients with negative sentinel lymph nodes, as well as in a selected group of patients with limited sentinel lymph node involvement. The pathologic features of the primary carcinoma and its sentinel lymph node metastases contribute to estimate the extent of non–sentinel lymph node involvement. This information is important to decide on further axillary treatment.
