BACKGROUND: Accurate intraoperative diagnosis of axillary malignancy facilitates completion axillary lymph node dissection (ALND) at the time of initial surgery. The capability to address both the primary tumor and axillary disease in a single procedure offers several advantages. This study was designed to define the predictive value of intraoperative touch preparation analysis of sentinel lymph nodes for axillary metastasis in breast cancer and to evaluate the ability of the technique to facilitate accurate synchronous ALND. METHODS: A consecutive cohort of patients with breast cancer at an Army medical center underwent intraoperative touch preparation analysis of sentinel lymph nodes concordant with initial excision. Those found to have sentinel nodes positive by touch preparation analysis underwent ALND at the initial procedure. Patients with negative sentinel nodes by touch preparation analysis, but positive by final pathology, underwent subsequent ALND. Results of the touch preparation analysis were compared with the final pathology. RESULTS: Over a 16-month period, 71 consecutive patients with breast cancer underwent initial excision and touch preparation analysis of 162 sentinel lymph nodes. Final pathology confirmed axillary metastasis in 32% (23 of 71) of patients. Of these, intraoperative touch preparation analysis identified 48% (11 of 23). There were no false positives or unnecessary axillary dissections based upon touch preparation results. Per sentinel node, the positive predictive value was 100%, the sensitivity was 47%, and the specificity was 100%. On a per patient basis, the positive predictive value was 100%, and the sensitivity and specificity were 48% and 100%, respectively. CONCLUSIONS: Intraoperative touch preparation analysis is an effective adjunct to sentinel lymph node biopsy. In our series, it facilitated a definitive cancer operation at the time of initial surgery in nearly 50% of patients, and ensured that no patient underwent an unnecessary axillary dissection.
