[Biopsy of sentinel lymph nodes in the treatment of breast carcinoma: experience of the Surgery Department of the Hospital of Parma].
Radical axillary nodes dissection in breast cancer is a standard for a correct staging, unfortunately this approach can cause several unpleasant sequelae and complications. Sentinel node biopsy applied to breast tumors could be a good option for predicting axillary nodes status avoiding complete dissection. The aim of this work is to report our experience with sentinel node biopsy during a period of 18 months. One hundred and nine patients with an infiltrating breast tumor T1 had been studied. There wasn't clinical and ultrasonographic evidence of axillary infiltration. Tumors had been injected on the day before surgery with a mixture of colloidal human albumin particles marked with 99m Technetium. In 108 out of 109 patients (99%) sentinel node had been identified using a gamma probe and biopsied during surgical intervention performed under local anesthesia. Sentinel node has been examined both with conventional histology and immunohistochemistry. In 26 cases the node was positive for metastases. Radical axillary dissection in this subgroup of patients showed that in 85% of them sentinel node was the only positive. We conclude that sentinel node biopsy can be a good alternative to traditional axillary dissection but there are still important questions about the best method of analysis and, before the technique become a routine procedure in breast cancer management, we should know the results of prospective clinical trials comparing survival of patients staged by sentinel node biopsy versus traditional axillary dissection.
