• W2003154557 abstract "Background: Axillary lymph nodes are surrogate markers for mapping the optimal management of axilla in breast cancer, and their assessment is pivotal to management and outcome. Until now, the assessment of axillary lymph nodes largely relies upon sentinel node biopsy (dual method) or conventional lymph node dissection. The morbidity of axillary lymph node dissection, however, is well known. Sentinel node biopsy is thus considered the standard of care in a node-negative axilla. However, developing economies face the dilemmas and challenges of matching up to the high cost of gamma probe, the vagaries of its learning curve, and, often, the advanced stage of disease at which the patients present. Also, with the advent of neo-adjuvant chemotherapy, the axilla can now be downstaged to a node negative status (N0). In this setting, a targeted four-node sampling (FNS) can offer a simple, reliable, and cost-effective approach for assessment of the axilla. Material and Methods: A total of 50 patients with locally advanced breast cancer who had received neo-adjuvant chemotherapy form the nucleus of this study. In each patient, axillary mapping was done using periareolar injection of 3 mL of methylene blue dye immediately before surgery. Four blue nodes from the specified anatomical site at level-I were picked up and subjected to frozen section. The axillary dissection was subsequently completed in a conventional manner in all patients irrespective of the outcome of frozen section and the entire specimen was the sent separately for histopathological examination. The outcome of frozen section was compared and correlated with the actual histopathological assessment of entire axilla to find out the sensitivity, specificity, and false negative rates of the technique. Results: The sensitivity and specificity of FNS were found to be 89.5% and 93.3%, respectively. The negative and positive predictive values were found to be 84.6% and 100%, respectively. Conclusions: It was observed that targeted FNS using methylene blue dye can serve as a reliable and inexpensive alternative to other techniques for addressal of axilla even in locally advanced breast cancers. This is particularly relevant in developing economies where majority patients still present as locally advanced; and high-end facilities, such as gamma camera and isotope studies, are scarce." @default.
