Abstract
Over the past 2 decades, lymphoscintigraphy and sentinel node biopsy have become widely accepted and are used by surgeons to stage many solid cancers, especially breast cancer. However, despite growing experience, there are a number of unresolved issues. In addition, the impact of a new radiopharmaceutical remains to be determined. The present article addresses some of these issues (either unresolved, recurrent, or newly emerged), with a focus on the properties of radiopharmaceuticals used for sentinel node mapping in breast cancer.

Preoperative lymphoscintigraphy predicts the successful identification but is not necessary in sentinel lymph nodes biopsy in breast cancer. Ann Surg Oncol 2007; 14:2215-20.

Abstract
BACKGROUND Although preoperative lymphoscintigraphy in sentinel lymph node biopsy (SLNB) for breast cancer patients is undergone commonly, its clinical significance remains controversial. METHODS We retrospectively analyzed our database that contained 636 consecutive breast cancer patients who received preoperative lymphoscintigraphy before SLNB. RESULTS The sentinel lymph nodes (SLNs) of 86.5% of patients were well imaged by lymphoscintigraphy, and SLN were located extra-axilla in 5.3% patients. The visualization of SLN in lymphoscintigraphy was not associated with histopathologic type, location, and stage of primary tumor, as well as the time interval from injection of radiocolloid to surgery. The negative lymphoscintigraphy results were associated with excision ;biopsy before injection of radiocolloid and positive axillary node statues. The SLN was successfully detected in 625 (98.3%) enrolled patients. Failure of surgical identification of axillary SLN was associated with whether hot spot was imaged by lymphoscintigraphy. However, we identified axillary SLN in 90 (90.9%) out of 99 patients with negative axillary findings in lymphoscintigram. The false negative rate of SLNB in our study was 16.0% (15 of 94) among patients of training group, and there was no significant difference in the false negative rate between patients who had axillary hot spot in lymphoscintigram and those who had not (P = .273). CONCLUSIONS Visualization of SLN in preoperative lymphoscintigraphy predicted the successful SLN identification. However, it was less informative for the location of SLN during operation. Considering the complexity, time consumed, and cost, lymphoscintigraphy should at present be undergone for investigation purposes only.

INTERNATIONAL SEMINARS IN SURGICAL ONCOLOGY 2005; 2:25. [PMID: 16277655 PMCID: PMC1308847 DOI: 10.1186/1477-7800-2-25] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2005] [Accepted: 11/08/2005] [Indexed: 12/28/2022]
Abstract
Current trends in patient care include the desire for minimizing invasiveness of procedures and interventions. This aim is reflected in the increasing utilization of sentinel lymph node biopsy, which results in a lower level of morbidity in breast cancer staging, in comparison to extensive conventional axillary dissection. Optimized lymphoscintigraphy with triangulated body marking is a clinical option that can further reduce morbidity, more than when a hand held gamma probe alone is utilized. Unfortunately it is often either overlooked or not fully understood, and thus not utilized. This results in the unnecessary loss of an opportunity to further reduce morbidity. Optimized lymphoscintigraphy and triangulated body marking provides a detailed 3 dimensional map of the number and location of the sentinel nodes, available before the first incision is made. The number, location, relevance based on time/sequence of appearance of the nodes, all can influence 1) where the incision is made, 2) how extensive the dissection is, and 3) how many nodes are removed. In addition, complex patterns can arise from injections. These include prominent lymphatic channels, pseudo-sentinel nodes, echelon and reverse echelon nodes and even contamination, which are much more difficult to access with the probe only. With the detailed information provided by optimized lymphoscintigraphy and triangulated body marking, the surgeon can approach the axilla in a more enlightened fashion, in contrast to when the less informed probe only method is used. This allows for better planning, resulting in the best cosmetic effect and less trauma to the tissues, further reducing morbidity while maintaining adequate sampling of the sentinel node(s).

Kim SC, Kim DW, Moadel RM, Kim CK, Chatterjee S, Shafir MK, Travis A, Machac J, Krynyckyi BR. Using the intraoperative hand held probe without lymphoscintigraphy or using only dye correlates with higher sensory morbidity following sentinel lymph node biopsy in breast cancer: a review of the literature. World J Surg Oncol 2005; 3:64. [PMID: 16194276 PMCID: PMC1262786 DOI: 10.1186/1477-7819-3-64] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2005] [Accepted: 09/29/2005] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND There are no studies that have directly investigated the incremental reduction in sensory morbidity that lymphoscintigraphy images (LS) and triangulated body marking or other skin marking techniques provide during sentinel lymph node biopsy (SLNB) compared to using only the probe without LS and skin marking or using only dye. However, an indirect assessment of this potential for additional sensory morbidity reduction is possible by extracting morbidity data from studies comparing the morbidity of SLNB to that of axillary lymph node dissection. METHODS A literature search yielded 13 articles that had data on sensory morbidity at specific time points on pain, numbness or paresthesia from SLNB that used radiotracer and probe or used only dye as a primary method of finding the sentinel node (SN). Of these, 10 utilized LS, while 3 did not utilize LS. By matching the data in studies not employing LS to the studies that did, comparisons regarding the percentage of patients experiencing pain, numbness/paresthesia after SLNB could be reasonably attempted at a cutoff of 9 months. RESULTS In the 7 studies reporting on pain after 9 months (> 9 months) that used LS (1347 patients), 13.8% of patients reported these symptoms, while in the one study that did not use LS (143 patients), 28.7% of patients reported these symptoms at > 9 months (P < 0.0001). In the 6 studies reporting on numbness and/or paresthesia at > 9 months that used LS (601 patients), 12.5% of patients reported these symptoms, while in the 3 studies that did not use LS (229 patients), 23.1% of patients reported these symptoms at > 9 months (P = 0.0002). Similar trends were also noted for all these symptoms at < or = 9 months. CONCLUSION Because of variations in techniques and time of assessing morbidity, direct comparisons between studies are difficult. Nevertheless at a minimum, a clear trend is present: having the LS images and skin markings to assist during SLNB appears to yield more favorable morbidity outcomes for the patients compared to performing SLNB with only the probe or performing SLNB with dye alone. These results are extremely pertinent, as the main reason for performing SLNB itself in the first place is to achieve reduced morbidity.
