Abstract
Sentinel lymph node biopsy, popularized in melanoma, has revolutionized the management of breast cancer. While the morbidity associated with axillary node dissection was once thought to be a requisite risk in order to appropriately stage the axilla, large validation studies have demonstrated that sentinel lymph node biopsy is a minimally invasive technique that can accurately predict nodal status. This technique has become an accepted practice in many centers, but there remain many controversies surrounding the technique itself, the pathologic evaluation of the sentinel node and the optimal management of patients with minimal nodal disease. The historic roots of this technique are discussed, along with the controversial issues surrounding the technique and the clinical trials that are currently ongoing.

Abstract
BACKGROUND Our objective was to assess the global cost of the sentinel lymph node detection [axillary sentinel lymph node detection (ASLND)] compared with standard axillary lymphadenectomy [axillary lymph node dissection (ALND)] for early breast cancer patients. PATIENTS AND METHODS We conducted a prospective, multi-institutional, observational, cost comparative analysis. Cost calculations were realized with the micro-costing method from the diagnosis until 1 month after the last surgery. RESULTS Eight hundred and thirty nine patients were included in the ASLND group and 146 in the ALND group. The cost generated for a patient with an ASLND, with one preoperative scintigraphy, a combined method for sentinel node detection, an intraoperative pathological analysis without lymphadenectomy, was lower than the cost generated for a patient with lymphadenectomy [€ 2947 (σ = 580) versus € 3331 (σ = 902); P = 0.0001]. CONCLUSION ASLND, involving expensive techniques, was finally less expensive than ALND. The length of hospital stay was the cost driver of these procedures. The current observational study points the heterogeneous practices for this validated and largely diffused technique. Several technical choices have an impact on the cost of ASLND, as intraoperative analysis allowing to reduce rehospitalization rate for secondary lymphadenectomy or preoperative scintigraphy, suggesting possible savings on hospital resources.

Abstract
Pre-operative lymphoscintigram for axillary sentinel lymph node biopsy (SLNB) may not be required for successful SLNB. The 117 consecutive patients who underwent SLNB had pre-operative lymphoscintigraphy. The operating surgeon was blinded to the results of the lymphoscintigram before SLNB. After SLNB was complete, the surgeon was unblinded to the results of the lymphoscintigram; re-exploration carried out if more nodes were predicted on the lymphoscintigram. 116 patients (99%) had successful SLNB before unblinding. In 85 patients (73%), operative findings corresponded with scintigraphic findings. In 26 patients (22%), the lymphoscintigram predicted more sentinel nodes than had been found; further nodes were identified and excised in only 4 patients (3%). None were positive for cancer. SLNB was successful in 99% of cases without pre-operative lymphoscintigraphy. Only 3% of patients had further nodes identified as a result of the lymphoscintigram. Pre-operative lymphoscintigraphy does not improve the ability to perform axillary SLNB during breast cancer surgery.

Abstract
BACKGROUND Controversy exists in the literature regarding the optimal site for lymphatic mapping in breast cancer. This study was designed to characterize lymphatic drainage patterns within the same patient after subareolar (SA) and peritumoral (PT) radiopharmaceutical injections and examine the impact of reader interpretation on reported drainage. METHODS In this prospective trial, 27 women with breast cancer underwent sequential preoperative SA and PT injections of 0.5 to 2.7 mCi of technetium-99 m filtered sulfur colloid 3 days or more apart. Patterns of radiopharmaceutical uptake were reviewed independently by two nuclear medicine physicians. Inter-reader agreement and injection success were assessed in conjunction with observed drainage patterns. RESULTS There was near perfect inter-reader agreement observed on identification of axillary LN drainage after PT injection (P = 0.0004) and substantial agreement with SA injection (P = 0.0344). SA injection was more likely to drain to only axillary LNs, whereas PT injection appeared more likely to drain to both axillary and extra-axillary LNs, although no statistically significant differences were found. All patients with extra-axillary drainage after PT injection (n = 6 patients) had only axillary drainage after SA injection. Dual drainage was observed for six patients with PT injection and one patient with SA injection. CONCLUSIONS Our findings suggest that radiopharmaceutical injected in the SA location has a high propensity to drain to axillary LNs only. After controlling for patient factors and demonstrating inter-reader agreement, the inability to demonstrate statistically significant differences in drainage based on injection site suggests that lymphatic drainage patterns may be a function of patient and tumor-specific features.

Abstract
BACKGROUND Sentinel lymph node (SLN) mapping has become the standard of care for axillary staging in women with early-stage breast cancer. The purpose of the study was to investigate the hypothesis that nonvisualization of SLN on lymphoscintigraphy (LSG) predicts a subset of patients at risk of having a substantial burden of axillary tumor as evidenced by higher rate of lymph node involvement. STUDY DESIGN We retrospectively reviewed the records of 1,500 patients who underwent dual-tracer SLN mapping for breast cancer between 1999 and 2004. LSG were reported as negative or positive. RESULTS Ninety-one percent had axillary SLN(s) identified on LSG imaging. In 133 of 134 (99.3%) patients with a negative LSG, SLN(s) was identified intraoperatively either by blue dye or hand-held gamma detection. SLN was positive in 28.4% of LSG nonvisualized group and was positive in 29.1% of LSG visualized group (p>0.05). A significantly higher percentage of women older than 50 years of age had nonvisualization of SLN (p<0.0001). Body mass index (calculated as kg/m2) was >30 in 42.5% of LSG nonvisualized group and in 26.3% in LSG visualized group (p<0.0001). CONCLUSIONS Failure to demonstrate axillary uptake by LSG appears to be related to technical factors and patient-related factors, such as body mass index and older age, but does not adversely affect SLN identification. The equivalent rate of positive SLNs in patients with a positive or negative LSG supports the null hypothesis that "failure to visualize" on LSG does not identify a subset of patients at higher risk of being axillary lymph node positive.

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.

Abstract
The technique of detection and resection of the sentinel lymph node applied to early breast cancer management aims to spare the patient with a low risk of lymph node involvement an unnecessary axillary lymphadenectomy. This innovating technique lies on the double hypothesis of an accuracy to predict non sentinel lymph node status and to induce a lower morbidity when compared with axillary lymphadenectomy. This multidisciplinary technique depends on surgeons, nuclear physicians and pathologists. In practice sentinel lymph nodes are detected thanks to two types of tracers, the Blue and the colloids marked with technetium, harvested by the surgeon guided by the blue lymphatic channel and the use of a gamma probe detection, analyzed by the pathologist according to a particular procedure with the concept of serial slices, and possibly immuno histo chemistry. The objectives of this review are to specify the state of knowledge concerning the different steps: detection, surgical resection and the pathological analysis of the sentinels lymph nodes and to focus on validated and controversial indications, and on the main ongoing trials.

Abstract
BACKGROUND Lymphoscintigraphy (LSG) can identify lymphatic drainage patterns before sentinel lymph node (SLN) biopsy is performed in patients with early-stage breast cancer, but the importance of extraaxillary SLNs seen on LSG is unknown. We assessed whether drainage patterns seen on LSG were associated with histologic findings in axillary SLNs recovered at SLN biopsy. STUDY DESIGN From a prospectively maintained database, we identified 1,201 clinically node-negative patients with invasive breast cancer who underwent preoperative LSG and axillary SLN biopsy. Patient and tumor characteristics, LSG results, and final SLN pathology results were examined. RESULTS LSG showed drainage to internal mammary (IM) nodes in 1.6% of patients, axillary nodes in 68.1%, both IM and axillary nodes in 19.8%, and no drainage in 10.3%. Drainage to IM nodes was observed for tumors in all quadrants of the breast. Patients with IM drainage had a younger median age than patients without IM drainage (51.8 versus 58.3 years, respectively; p < 0.001). The intraoperative axillary SLN identification rate was higher when axillary drainage was observed on LSG than when it was not observed (98.7% versus 93.0%, respectively; p < 0.001), but the LSG drainage pattern was not associated with pathologic status of the SLN or number of metastatic SLNs. At a median followup of 32 months, 4 patients had regional nodal recurrence. CONCLUSIONS Almost one-fourth of patients had lymphatic drainage to the extraaxillary lymph nodes, particularly the IM nodes, seen on LSG. Extraaxillary drainage seen on LSG did not preclude identification of axillary SLNs at operation. Longterm followup of patients with lymphoscintigraphic evidence of extraaxillary drainage is needed to determine whether regional and systemic recurrence patterns differ in these patients.

Abstract
The aim of this study was to identify the variables associated with successful peroperative sentinel lymph node (SLN) localization. We studied 201 patients with T1, T2, N0 invasive breast cancer who underwent a SLN procedure from 1999 to 2003. Of these 201 patients, 55 underwent peritumoral and 146 underwent periareolar radioisotope injection before the blue dye injection. All patients were operated on by breast conservative surgery and axillary dissection after SLN biopsy. Age, weight, menopausal status, previous biopsy, localization of the tumor, results of lymphoscintigraphy, site of radiotracer injection, tumor size, tumor grade, experience of surgeons, and the number of invaded axillary nodes were analyzed to determine whether they had any significant correlation with successful identification of SLN. Variables found to have a statistically significant influence on the SLN identification rate and on preoperative lymphoscintigraphy identification were introduced into a univariate and multivariate logistic regression model. In multivariate analysis, successful lymphoscintigraphy (P < 0.0001) and the absence of metastatic axillary nodes (P < 0.005) were associated with successful identification of SLNs. The peritumoral injection of radiotracer (P < 0.001), patient age > 60 years (P < 0.003), and localization of the tumor in the upper outer quadrant (P < 0.004) were associated with failure of lymphoscintigraphic visualization of SLN. The technique of SLN detection thus appears to be better for patients with low risk of invaded axillary lymph nodes.

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).

Abstract
BACKGROUND Radiation to the internal mammary chain (IMC) may be indicated for breast carcinoma patients with positive axillary sentinel lymph nodes (SLNs) and lymphoscintigraphic evidence of drainage to the IMC. The purpose of this study was to identify predictors of IMC drainage in patients with positive axillary SLNs. METHODS The records of 297 breast carcinoma patients with positive axillary SLNs and preoperative lymphoscintigraphy were reviewed between 1995 and 2002. Radiolabeled colloid was injected peritumorally with lymphoscintigraphy performed 30-60 minutes later. Drainage to the regional nodes of 279 patients was seen on lymphoscintigraphy. Associations among patient and tumor-related factors and drainage to the IMC were examined. RESULTS Drainage to the IMC on lymphoscintigraphy was seen in 63 patients (21%). IMC drainage only occurred in 4 patients, and 59 patients had both axillary and IMC drainage. The only variable that correlated with IMC drainage was tumor location (P = 0.017). Rates of drainage to the IMC were 14.1% for upper outer quadrant (n = 128), 16.7% for upper inner quadrant (n = 30), 31.6% for lower outer quadrant (n = 19), 42.9% for lower inner quadrant (n = 14), and 28.4% for central tumors (n = 88). IMC drainage rates differed significantly between upper and lower tumors (lower 36.4% vs. central 28.4% vs. upper 14.6%, P = 0.003) but not between medial and lateral tumors (medial 25.0% vs. central 28.4% vs. lateral 16.3%, P = 0.077). CONCLUSIONS Patients with tumors in the lower or central breast and positive axillary SLNs have increased incidence of drainage to the IMC. Preoperative lymphoscintigraphy can help to define the nodal basins at risk for harboring disease.

Abstract
Lymphoscintigraphy (LS) may identify sentinel lymph nodes (SLNs) outside the axilla. Biopsy of these nodes could improve the accuracy of lymphatic mapping (LM) for breast cancer (BC) if a significant number of tumor-positive extra-axillary sentinel nodes are identified. To address this, we evaluated the impact of the use of preoperative LS and biopsy of axillary and internal mammary SLNs in women with BC. From October 1997 to July 2003, 175 women with breast cancer received technetium sulfur colloid, and images were obtained. Isosulfan blue dye was injected intraoperatively, and LM of the axillary and internal mammary lymph node basins was performed with a hand-held gamma probe. The anatomic location and histologic status of all SLNs identified with LS and LM was recorded, and the impact of the findings on LS and internal mammary LM were evaluated. LS showed SLN in 127/175 (73%) women and “hot spots” were found with the gamma probe in 142/175 (81%). At least one SLN was identified by LM in 168/175 (96%) patients, and 48/168 (29%) had metastases. One hundred sixty-two of 168 (96%) patients had SLN exclusively in the axilla. Only 10 of 175 (6%) women had internal mammary (IM) SLNs seen on LS. LM identified IM sentinel nodes in 6 of these 10 patients, but none were involved with tumor. Preoperative lymphoscintigraphy and biopsy of internal mammary sentinel nodes do not enhance the accuracy of lymphatic mapping for breast cancer. Omitting lymphoscintigraphy reduces the complexity and cost of lymphatic mapping without compromising the identification of tumor-positive sentinel nodes.

Intradermal radioisotope is superior to peritumoral blue dye or radioisotope in identifying breast cancer sentinel nodes. J Am Coll Surg 2004; 199:561-6.

Abstract
BACKGROUND Sentinel lymph node (SLN) mapping and biopsy have emerged as the technique of choice for axillary staging of breast cancer. Several methods have been developed to identify SLNs, including peritumoral or intradermal injection of isosulfan blue dye or technetium sulfur colloid (TSC). We hypothesize that intradermal TSC is the optimal mapping technique and can be used alone to identify SLNs. STUDY DESIGN From March 1997 through January 2001, 180 women with T1 and T2 invasive breast cancer and clinically negative axilla underwent SLN mapping and biopsy. Peritumoral TSC was injected in 74 patients, 62 of whom also received peritumoral blue dye. Intradermal TSC (above tumor) was performed in 94 patients, 76 of whom also received peritumoral blue dye. Technetium-rich nodes were identified intraoperatively using a hand-held gamma probe and blue nodes were identified visually. Hematoxylin- and eosin-stained SLN sections were examined by light microscopy for breast cancer metastases. RESULTS Overall, the SLN mapping procedures were successful in 91% of patients. Peritumoral and intradermal TSC were successful in identifying SLNs in 78% and 97% of patients, respectively. Peritumorally injected isosulfan blue was successful in identifying 83% of SLNs. Intradermal TSC was found to be superior to peritumoral TSC and peritumoral blue dye in identifying SLNs (p = 0.00094, chi-squared, and p = 0.020, ANOVA). CONCLUSIONS SLN mapping by intradermal TSC has a significantly higher success rate than peritumoral TSC or blue dye. There was minimal benefit in identifying additional SLNs with addition of peritumoral blue dye to intradermal TSC. So, SLN mapping and biopsy using intradermal-injected TSC can be used alone to effectively stage the axilla for breast cancer.

Abstract
Lymphatic mapping and sentinel lymphadenectomy has become an important tool for axillary lymph node staging in women with early-stage breast cancer. This review examines data regarding the staging accuracy, indications and technical aspects of the procedure, and clinical trials investigating the technique. Multiple studies now confirm that sentinel lymphadenectomy accurately stages the axilla and is associated with less morbidity than axillary dissection. Blue dye, radiocolloid, or both can be used to identify the sentinel node, and several injection techniques may be used successfully. Many patient factors previously thought to affect accuracy of the procedure have now been shown to be of limited significance. The indications for the procedure are expanding, and the histopathologic evaluation of the sentinel node and the role of lymphoscintigraphy have been clarified. Clinical trials are now underway that will determine the prognostic significance of micrometastases and the therapeutic benefit of axillary dissection in women with and without sentinel node metastases. Incorporation of sentinel lymphadenectomy into routine clinical practice will maintain accurate axillary staging with lower morbidity and improved quality of life for women with early-stage breast cancer.

Abstract
Technical advances in the past several years have simplified and improved sentinel lymph node (SLN) biopsy for breast cancer. The use of alternative injection sites (skin or subareolar) yields high SLN identification rates and may shorten the learning curve associated with standard peritumoral injection. The dual-agent (radiocolloid plus blue dye) technique is now recommended to decrease false-negative rates, especially when surgeons are just learning how to perform SLN biopsy. Methylene blue may be an acceptable substitute for isosulfan blue dye and is associated with fewer hypersensitivity reactions. Hand-held gamma probes are now smaller and more maneuverable, with better shielding for directional detection of gamma rays. Routine preoperative lymphoscintigraphy can be avoided, thus facilitating operating room scheduling. Surgeons can use minimally invasive techniques to identify and remove internal mammary SLNs.

Abstract
Despite the widespread use of sentinel lymph node biopsy (SLNBx) in the surgical management of breast cancer patients, several areas remain controversial. The following controversies are reviewed: Learning curves and validation studies. There clearly is a learning curve, and a completion ALND should be done until adequate proficiency is exhibited, both in terms of identification and false-negative rates. Location of injection. Intradermal injection offers superior identification rates compared with peritumoral injection, with comparable false-negative rates. Subareolar injection is as accurate as peritumoral injection. The value of scintigraphy. Routine scintigraphy does not enhance identification or false-negative rates. Mapping agents. Blue dye and radioactive tracer combined to provide a higher identification rate than either used alone.SLNBx in DCIS. In patients with a high risk of microinvasion, such as large tumors, a mass or high-grade DCIS-SLNBx is justified.SLNBx following neoadjuvant chemotherapy. Although there is evidence that SLNBx after neoadjuvant chemotherapy may be accurate, these data should be applied cautiously. Implications of non axillary SLN, especially internal mammary nodes. Data do not support routine resection of internal mammary sentinel lymph nodes outside a clinical trial. Implications of micrometastases in the sentinel lymph node seen only on immunohistochemistry. Since the significance of such metastases is unclear, decisions regarding treatment of these patients should be individualized. The value of completion axillary lymph node dissection. Is being addressed in clinical trials. Until those studies mature, completion ALND should be performed for patients with SLN metastases, but may be abandoned for patients with a negative SLN.

Abstract
Traditional lymphadenectomy is being replaced by sentinel node biopsy in initial management of early stage breast cancer. The aim of this study was to validate the technique in our center, where we perform preoperative lymphoscintigraphy and intraoperative detection of sentinel node, after periareolar radiotracer and peritumoral blue dye injection. Sixty patients, breast cancer stages I and II, were included. Lymphatic mapping was performed the day before surgery, after the administration of 74 MBq 99mTc sulfur colloid in periareolar subdermal tissue. Surgical detection of sentinel node through gamma probe was followed by intraoperative and occasionally delayed biopsies. Finally, full axillary node dissection was completed. Lymphoscintigraphy identified sentinel node in 78% of the patients (47/60): 43 in axilla, 4 in internal mammary chain. Probe guided axillary detection was achieved in 88% (53/60): in every patient with axillar migration in scan, in 9/13 without imaged drainage and in 1/4 with internal mammary chain migration. Sensitivity of blue dye technique was 75% (45/60), the concordance between both procedures being high. Considering both, the overall success rate of surgical detection was 90% (54/60); if we exclude those patients who showed exclusive extraaxillar drainage, the success rate reaches 95%. Malignancy was found in 24% of sentinel nodes removed (13/54); it being the only metastatic axillary node in 4/13. No false negative sentinel nodes were found. Therefore, negative predictive value and accuracy were 100%. These results allow us to validate the technique in our center.

Abstract
The purpose of this study was to examine the use of ultrasound (US)-guided core biopsy of axillary nodes in patients with operable breast cancer. The ipsilateral axillae of 187 patients with suspected primary operable breast cancer were scanned. Nodes were classified based on their shape and cortical morphology. Abnormal nodes underwent US-guided core biopsy/fine needle aspiration (FNA), and the results correlated with subsequent axillary surgery. The nodes were identified on US in 103 of 166 axillae of patients with confirmed invasive carcinoma. In total, 54 (52%) met the criteria for biopsy: 48 core biopsies (26 malignant, 20 benign node, two normal) and six FNA were performed. On subsequent definitive histological examination, 64 of 166 (39%) had axillary metastases. Of the 64 patients with involved nodes at surgery, preoperative US identified nodes in 46 patients (72%), of which 35 (55%) met the criteria for biopsy and 27 (42%) of these were diagnosed preoperatively by US-guided biopsy. In conclusion, US can identify abnormal nodes in patients presenting with primary operable breast cancer. In all, 65% of these nodes are malignant and this can often be confirmed with US-guided core biopsy.

Abstract
PURPOSE The authors' purpose was to explore the association between mammographic findings and drainage patterns on lymphoscintigrams obtained during sentinel node procedures for breast carcinoma. MATERIALS AND METHODS From July 1997 to March 2000, 132 patients with breast cancer who were included in a prospective mammography-pathology correlation and staging database were imaged 2 hours after perilesional injection of 1 mCi filtered (0. 22 microm) Tc-99m sulfur colloid (4 ml volume) before sentinel node procedures. RESULTS Sixty-four percent of the scans showed axillary drainage only, 9% showed axillary and internal mammary drainage, and 4% revealed internal mammary drainage only. Twenty-three percent of scans showed no drainage. Of the patients who showed drainage, 17% showed drainage to the internal mammary basin, and 5% showed this exclusively. Internal mammary drainage was seen in 18% (10 of 57) of lateral, 21% (6 of 29) of medial, and 14% (1 of 7) of subareolar lesions (P = NS). No drainage was seen in 22% of patients with predominantly fatty mammographic parenchymal density (>50%) compared with only 8% of patients with predominantly dense (>50%) parenchyma (P < 0.05). Failure to show drainage was more common in women older than 50 years (P < 0.05). Axillary sentinel nodes were identified surgically in 73% of patients with negative scan findings. There was no significant association between scintigraphic drainage and mammographic soft tissue tumor size and appearance, histologic findings, or axillary node status. CONCLUSIONS Dense mammographic parenchyma and age less than 50 years are associated with identification of lymphatic drainage on lymphoscintigrams performed before sentinel node procedures in 91% to 92% of patients. Internal mammary drainage, present in 18% of lateral and 21% of medial lesions, may direct therapy to include internal mammary lymph nodes.

Abstract
BACKGROUND Lymphatic mapping (LM) for breast cancer has made internal mammary node (IMN) detection practical and dependable. This study demonstrates the necessity of IMN removal when suggested by intraoperative radioguided surgery detection. METHODS From April 1998 to July 2000, 1273 patients underwent LM for breast cancer. LM was performed using the combined dye and radiocolloid technique. Patients were scanned operatively with a gamma probe over the IMN area, and most underwent preoperative lymphoscintigraphy. Nodes were removed from patients in whom radioactivity was detected in the internal mammary area. RESULTS Thirty of the 1273 (2.4%) patients mapped had at least one IMN removed. Twenty-two of 30 (73.3%) had inner quadrant lesions. Five of 30 (16.7%) patients had IMNs that were positive for metastatic disease. Three of these five had no metastatic spread to the axillary sentinel lymph node (SLN). One of thirty (3.3%) patients with IMN localization had neither hot nor blue nodes detected in an SLN procedure. CONCLUSIONS Radioguided SLN detection should be attempted in the IMN basin with all tumors. If an IMN is identified, it should be removed. IMN biopsy is a feasible, low-risk procedure when directed by radioguided LM and provides a guide for radiotherapy for patients with positive IMNs.
