ABSTRACT
The accuracy of the sentinel node technique in the evaluation of axillary node involvement in breast cancer was evaluated in 83 consecutive patients with monofocal T1-2 carcinoma, who were clinically N0 and who underwent lymphoscintigraphy with 99mTc-colloid integrated with intraoperative sentinel node detection by a portable probe. Lymphoscintigraphy revealed at least one sentinel node in 75 patients (90.4%), always identified by the probe. In eight patients (9.6%) the sentinel node was detected neither by lymphoscintigraphy nor by the probe. All removed lymph nodes were analyzed by hematoxylin-eosin histology and the sentinel node by immunostaining. In 28/75 patients (37.3%) at least one metastatic axillary lymph node was detected; in 16 of the 28 N+ subjects (57%) only the sentinel node was positive. The false negative rate (sentinel node negative/other axillary lymph nodes positive) was 17.85% (5/28 patients). In 9/23 patients (39%) micrometastases were found in the sentinel node only. In conclusion, specific sentinel node positivity in 57% of cases supports the validity of the sentinel node concept. Moreover, nine patients would have been considered N0 by standard hematoxylin-eosin histology without sentinel node-aided immunostaining. A 17.8% false negative rate calls for caution in patients with negative sentinel nodes.
