ABSTRACT Radioguided occult lesion localization (ROLL) is a new technique to detect nonpalpable breast tumors. We report our experience using injection of a single radiotracer to localize occult lesions together with sentinel lymph node (SLN) biopsy (SNOLL). The aim of this series was to evaluate the feasibility of the technique, its efficacy, and the rate of reoperation.
Under sonographic guidance, a nanocolloidal tracer was injected peritumorally above and below the lesion. A handheld gamma probe detector was used to locate and to guide its surgical removal. An intraoperative (IO) macroscopic examination of the specimen with margins evaluation and IO imprint cytology of SLN was always performed.
The targeted lesion was localized and removed in all cases. Final pathological diagnosis identified invasive in 70 patients and ductal carcinoma in situ (DCIS) in 2 patients. The average size of the resected lesion was 11 mm (4-50 mm). In 61 out of the 72 patients (85%), the breast specimen had clear and large margins. Sentinel lymph node (SLN) biopsy was performed in 70 patients with an identification rate of 90%. Final pathological SLN metastasis rate approached 25% (pN1 14%, pN1(mi) 11%). Despite intraoperative examination of the specimen, a total of 29% (21 out of 72) patients had to be reoperated (8 patients for involved margins, 10 patients for an involved SLN, and 3 for both).
This technique with a single nanocolloid tracer used both for ROLL and SLN detection is reliable for removing nonpalpable lesions. The use of this technique may have implications for further reducing reoperation rates.

    ABSTRACT: Wire localization (WL) of nonpalpable breast cancers on the day of surgery is uncomfortable for patients and impacts operating room efficiency. Radioactive seed localization (RSL) before the day of surgery avoids these disadvantages. In this study we compare outcomes of our initial 6-month experience with RSL to those with WL in the preceding 6 months. Lumpectomies for invasive or intraductal cancers localized with a single (125)iodine seed (January-June 2012) were compared with those using 1 wire (July-December 2011). Surgeons and radiologists did not change. Positive and close margins were defined as tumor on ink and tumor ≤1 mm from ink, respectively. Demographic and clinical characteristics and outcomes were compared between RSL and WL patients. There were 431 RSL and 256 WL lumpectomies performed. Clinicopathologic characteristics did not differ between groups. Most seeds (90 %) were placed before the day of surgery. Positive margins were present in 7.7 % of RSL versus 5.5 % of WL patients, and 16.9 % of RSL versus 19.9 % of WL had close margins (p = 0.38). The median operative time was longer for lumpectomy and sentinel lymph node biopsy (SLNB) in the RSL group (55 vs. 48 min, p < 0.0001). There was no significant difference in the volume of tissue excised between groups. In the first 6 months of RSL, operative scheduling was simplified, while rates of positive and close margins were similar to those seen after many years of experience with WL. Operative time was slightly longer for RSL lumpectomy and SLNB; we anticipate this will decrease with experience.

    ABSTRACT: Sentinel node and occult lesion localization (SNOLL) is an alternative to wire-guided localization (WGL) for guiding surgical excision of non-palpable breast cancer and the performance of concurrent sentinel lymph node biopsy (SLNB). This review provides an overview of the available evidence on the accuracy of SNOLL in patients undergoing breast-conserving surgery. PubMed, Embase and the Cochrane Library were searched systematically in April 2013 for studies that address localization of non-palpable breast cancer using SNOLL. Studies were deemed eligible if they reported on the proportion of patients with tumour-positive margins, re-operation rates, performance of concurrent SLNB and considered non-palpable malignant disease only (invasive and in situ) in SNOLL. Seven studies reported data on SNOLL in 983 patients with non-palpable breast cancers. Overall complete resection rates ranged from 82 to 90.5 per cent. Second operation rates ranged between 2 and 12 per cent and SLNB success rates between 88.2 and 100 per cent. The risk of failed surgical localization was between 0 and 4.5 per cent in the studies. Available scientific evidence suggests that SNOLL is a safe and accurate technique for the localization of non-palpable breast cancers.

    ABSTRACT: 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. 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. 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. 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.
