Abstract

BACKGROUND:

Sentinel node and occult lesion localization (SNOLL) calls for a combination of two specific procedures: intraoperative detection of sentinel lymph node (SLN) via gamma probe and radioguided occult lesion localization (ROLL). This applies to nonpalpable invasive breast cancer or high-grade in situ carcinoma. As opposed to standard techniques, today's handheld gamma cameras enable intraoperative scintigraphic images.

METHODS:

A cohort (N = 186) of consecutive patients with breast cancer was subjected to radioguided conservative surgery (quadrantectomy and SLN biopsy), using a standard gamma probe and a high-resolution handheld camera. Intraoperative SLN frozen section was also performed.

RESULTS:

Neoplastic lesions were removed in 99.4% of all patients, and SLN biopsy was achieved in 99%. Of the 137 patients with invasive cancer, SLN metastasis was confirmed in 21. In 12% of patients, a second operation was required for close or tumor-positive surgical margins.

DISCUSSION:

This combination of procedures represents an improvement in the surgical management of occult breast carcinomas and is the method of choice for accurate tumor localization and SLN biopsy. Handheld cameras have the potential to become highly useful intraoperative aids.
