Abstract
AIMS The aim of this study was to assess the value of lymphoscintigraphy in general and extra-axillary lymph node biopsy in particular, based on our experience with sentinel biopsy in 128 consecutive woman undergoing surgery for breast cancer. METHODS Sentinel node biopsy was performed with the aid of isotope, hand held gamma probe, blue dye and lymphoscintigraphy in 83 patients. Injection technique was peritumoral or intratumoral. Lymphoscintigraphy was performed 2-4 h following isotope injection. RESULTS Eighteen lymposcintigraphies were negative (21.7%). The sentinel node was found in 14 of these cases. We were unable to identify the sentinel node(s) in four patients (4/83; 4.8%). All in all 20/25 (80%) extra-axillary nodes were located and taken out. Only two of these (2/20, 10%) were positive for metastatic disease on histological examination. The adjuvant treatment plans for these patients were not altered in response to these findings. No positive extra-axillary node(s) with simultaneous normal axillary sentinel node was found. CONCLUSIONS In this serie, lymphoscintigraphy and biopsy of extra-axillary sentinel nodes added nothing but time, risk and cost to the procedure.

Abstract
BACKGROUND Sentinel node biopsy is rapidly gaining popularity as a less invasive approach to nodal staging in breast cancer. The optimal route of injection of radiocolloids and dye is controversial. The purpose of the present paper was to review and assess the literature. METHODS A MEDLINE search for reports of studies involving different injection sites of colloid and/or dye was performed. RESULTS Although controversial, current evidence suggests that subareolar (SA) or intradermal/subdermal (ID/SD) injection will map the same axillary sentinel nodes (SN) as peritumoral (PT) injection in the vast majority of cases, is at least as successful, and is better logistically. Peritumoral, but not alternative routes, identify extra-axillary sentinel nodes, which are important in a minority of patients. CONCLUSIONS It is recommended that at least some of the radiocolloid be injected peritumorally to avoid missing those SN not located in the ipsilateral axilla. Injection of the dye and a portion of radiocolloid in an ID/SA location is reasonable to take advantage of the general ease and accuracy of ID/SA injections in identifying axillary SN.

Abstract
BACKGROUND The aim of this study was to assess the capacity of positron emission tomography (PET) with fluorodeoxyglucose (FDG) to determine axillary lymph node status in patients with breast cancer undergoing sentinel node (SN) biopsy. METHODS Thirty-two patients with breast cancer and clinically negative axillary nodes were recruited. All patients underwent FDG-PET before SN biopsy. After SN biopsy, all patients underwent complete axillary lymph node (ALN) dissection. RESULTS The SNs were identified in all patients. Fourteen patients (43.8%) had metastatic SNs (macrometastatic in seven, micrometastatic in six, and isolated tumor cells in one). The false-negative rate of SN biopsy was 6.6% (1 in 15). FDG-PET identified lymph node metastases in 3 of the 14 patients with positive SNs. The overall sensitivity, specificity, and positive and negative predictive values of FDG-PET in the diagnosis of axillary metastasis were 20%, 100%, 100%, and 58.6%, respectively. No false-positive findings were obtained with FDG-PET. CONCLUSIONS This study demonstrates the limitations of FDG-PET in the detection of ALN metastases in patients with early breast cancer. In contrast, FDG-PET seems to be a specific method for staging the axilla in breast cancer. SN biopsy can be avoided in patients with positive FDG-PET, in whom complete ALN dissection should be the primary procedure.

Abstract
OBJECTIVE To determine whether subtumoral injection of radiocolloid is useful for lymphoscintigraphic visualization of the internal mammary node and in sentinel lymph node (SLN) biopsy of the axilla in breast cancer patients. SUMMARY BACKGROUND DATA The presence of retromammary lymphatics connecting to the axillary and internal mammary basins has been demonstrated by early anatomic studies. Thus, it is hypothesized that some lymph, especially that from the parenchyma under the tumor, may drain into both the axillary and internal mammary basins. METHODS Patients (n = 196) with T1-2, N0 breast cancer underwent preoperative lymphoscintigraphy with radiocolloid (technetium 99m tin colloid) injection into various sites of the breast, followed by SLN biopsy using the combined method with blue dye. Patients were divided into four groups: group A (n = 41), peritumoral injection of both radiocolloid and blue dye; group B (n = 70), periareolar radiocolloid and peritumoral blue dye; group C (n = 45), intradermal radiocolloid and periareolar blue dye; and group D (n = 40), subtumoral radiocolloid and intradermal blue dye. A retrospective analysis of 1,297 breast cancer patients who underwent extended radical mastectomy with internal mammary node dissection was also conducted to determine the relationship between vertical tumor location (superficial or deep) and frequency of axillary and internal mammary node metastases. RESULTS One patient (2%) in group A, 3 (4%) in group B, 0 (0%) in group C, and 15 (38%) in group D exhibited hot spots in the internal mammary region on lymphoscintigraphy (P <.001, group D vs. the other groups). The concordance rate of radiocolloid and blue dye methods in detection of SLNs in the axillary basin was significantly lower in group D than in the other groups. In contrast, the mismatch rate (some SLNs were identified by radiocolloid and other SLNs were identified by blue dye, but no SLN was identified by both in the same patient) was significantly higher in group D than in the other groups. In patients treated with extended radical mastectomy, positivity of axillary and internal mammary metastases was significantly higher in patients (n = 215) with deep tumors than those (n = 368) with superficial tumors. CONCLUSIONS These results suggest the presence of a retromammary lymphatic pathway from the deep portion of the breast to both axillary and internal mammary basins, which is distinct from the superficial pathway. Therefore, SLN biopsy with a combination of subtumoral and other (peritumoral, dermal, or areolar) injections of radiocolloid will improve both axillary and internal mammary nodal staging.

Abstract
PURPOSE To evaluate the role of breast tumor location on survival in patients with breast cancer. PATIENTS AND METHODS We evaluated tumor location within the breast on breast cancer-specific survival (BCSS) and overall survival (OS) in patients with invasive breast cancer using the Surveillance, Epidemiology, and End-Results (SEER) registries in the United States. Effects on survival were evaluated according to age, stage, tumor site, tumor size, grade, axillary lymph node status, extent of surgery, and radiotherapy (RT). A multivariate model was used with complete data on 45,880 patients. The median follow-up was 59 months. RESULTS Patients with outer tumor location demonstrated superior BCSS on Kaplan-Meier analysis for both local stage (node-negative, P <.001) and regional stage disease (node-positive, P =.0002). For BCSS, the hazard ratio (HR) for inner quadrant location compared with outer quadrant was 1.31 (95% confidence interval [CI], 1.19 to 1.37; P <.001); and for OS, the HR was 1.12 (95% CI, 1.05 to 1.17; P <.001). When ER and PR status were included in the model, the HR for inner quadrant location compared with outer quadrant was 1.27 for BCSS (95% CI, 1.16 to 1.40; P <.001) and 1.11 for OS (95% CI, 1.03 to 1.19; P =.004). Patients treated by lumpectomy that received RT had a superior OS compared with patients that did not receive RT in both local (HR, 0.52; 95% CI, 0.48 to 0.61; P <.001) and regional (HR, 0.63; 95% CI, 0.56 to 0.72; P <.001) stage disease. Mastectomy patients with local stage disease that received RT had a diminished OS (HR, 1.24; 95% CI, 1.02 to 1.50; P =.033). CONCLUSION On multivariate analysis, incorporating data on age, stage, tumor site, tumor size, grade, ER and PR status, axillary lymph node status, extent of surgery, and RT, this SEER registry-based study demonstrates that medial tumor location adversely impacts BCSS and OS.

Abstract
BACKGROUND The impact of regional therapy on survival of patients with invasive breast cancer remains controversial. Regional therapies discussed include axillary lymph node dissection (ALND), internal mammary node dissection, and locoregional radiotherapy. METHODS Prospective randomized clinical studies of regional therapy were reviewed using, as a source, Medline, main review articles on the related topic, and statements from consensus conference. RESULTS Although a number of randomized clinical studies have failed to demonstrate the benefits of regional treatment for survival, it is still a matter of debate whether ALND or regional radiotherapy alone can have a small but significant beneficial effect on the survival of breast cancer patients. However, recent studies have suggested that survival can be enhanced by interaction of postmastectomy locoregional radiotherapy with adjuvant systemic therapy. CONCLUSIONS Locoregional control is important for enhancing survival in the presence of adjuvant systemic therapy. Although only a few randomized controlled trials show conclusively the survival benefit of local therapies, it is expected that in clinical practice, the node-positive or other high-risk breast cancer patients given systemic treatment will be more frequently treated with postmastectomy radiation.

Abstract
The purpose of this study was to evaluate the occurrence of lymphatic drainage to non-axillary sentinel nodes and to determine the implications of this phenomenon. A total of 549 breast cancer patients underwent lymphoscintigraphy after intratumoural injection of (99m)Tc-nanocolloid. The sentinel node was intraoperatively identified with the aid of intratumoural administered patent blue dye and a gamma-ray detection probe. Histopathological examination of sentinel nodes included step-sectioning at six levels and immunohistochemical staining. A sentinel node outside level I or II of the axilla was found in 149 patients (27%): internal mammary sentinel nodes in 86 patients, other non-axillary sentinel nodes in 44 and both internal mammary and other non-axillary sentinel nodes in nineteen patients. The intra-operative identification rate was 80%. Internal mammary metastases were found in seventeen patients and metastases in other non-axillary sentinel nodes in ten patients. Staging improved in 13% of patients with non-axillary sentinel lymph nodes and their treatment strategy was changed in 17%. A small proportion of clinically node negative breast cancer patients can be staged more precisely by biopsy of sentinel nodes outside level I and II of the axilla, resulting in additional decision criteria for postoperative regional or systemic therapy.

Abstract
A 35 year old woman with biopsy proved breast cancer was submitted for sentinel node (SN) biopsy. Preoperative lymphoscintigraphy displayed both axillary and internal mammary (IM) uptake foci consistent with SNs. Full axillary dissection was completed because of a greater-than 2 cm primary lesion. Two axillary SNs were excised. An IM SN was also excised through the second intercostal space, with the aid of the gamma probe. Fourteen axillary nodes, including SNs, were negative, whereas the IM SN harbored several metastatic implants. Implications for staging, prognosis and further therapy of such IM-only positive sentinel nodes are discussed.

Abstract
Internal mammary lymph-node (IMN) metastases in breast carcinomas have a major influence on survival, comparable with the influence of axillary lymph-node metastases (ALNM). Prospective, randomized trials have demonstrated that complete IMN dissection as part of extended radical mastectomy does not improve overall or disease-free survival. In the subset of patients with tumours 1cm or less in size and no ALNM, information on IMN status would provide important information. In these cases, the presence of IMN metastases would change the staging from stage I to stage IIIB, according to the current tumour, node and metastasis classification. More importantly, it would influence these patients' adjuvant treatment. Lymphatic mapping for sentinel lymph-node (SLN) biopsy has demonstrated extra-axillary drainage in up to 35% of patients. Recent reports have demonstrated the feasibility of internal mammary sentinel lymph-node (IM-SLN) biopsy. Here we review the general prognostic and clinical significance of tumor location and lymph-node metastases in breast cancer and discuss the specific factors associated with IMN identification, metastases and treatment in the pre-SLN and SLN eras. Based on our review, we propose an algorithm for a selective approach to IM-SLN in breast cancer.

Abstract
BACKGROUND The nodal status remains the most important prognostic factor in breast cancer. While evaluation of the axillary lymph nodes remains a standard of practice, evaluation of the internal mammary lymph nodes is no longer routinely performed. In the era of extensive radical mastectomies, it was shown that up to 40% of breast cancer patients had nodal metastases in the internal mammary chain. This resulted in up to 10% of presumed "node-negative" patients actually being node-positive when the internal mammary nodes were examined. In the era of sentinel node biopsies, hot internal mammary nodes on lymphoscintigraphy are sometimes encountered and confusion exists regarding the appropriate approach to these nodes. New advances in endoscopic surgery have enabled a minimally invasive approach to the mediastinum. The aim of this study was to evaluate the feasibility of thoracoscopic internal mammary sentinel node biopsy in an animal model. MATERIALS AND METHODS Five farm pigs were injected with isosulphan blue under the right upper nipple. After a sentinel node was identified, it was dissected thoracoscopically. RESULTS In all the animals, an internal mammary blue node was easily identified 1-5 min after the injection and dissected with thoracoscopic instruments without significant damage to other thoracic structures. The procedure length averaged 30 to 60 min. CONCLUSIONS Thoracoscopic internal mammary sentinel node biopsies are feasible, short, easy to perform, minimally invasive, and well focused toward a sentinel node. Well-planned phase I studies should be initiated to further evaluate this new technique.

Abstract
Radiation therapy has been shown to statistically significantly reduce the risk of locoregional recurrence in high-risk patients with operable breast cancer following mastectomy and systemic therapy. Recent trials have also demonstrated a significant survival benefit following radiotherapy in high-risk patients. Therefore, it is important to identify the patients who could potentially derive that survival benefit and to not offer treatment to those patients who are not at increased risk for failure. Established risk factors that predict for increased rates of locoregional recurrence include axillary lymph node involvement and T3 (or T4) disease. While treatment-related factors, such as the extent of the axillary dissection and extent of lymph nodal positivity, also undoubtedly affect locoregional recurrence, additional studies are needed to define the magnitude of their risk. Locoregional patterns of failure have identified the chest wall and supraclavicular/infraclavicular regions to be the most common sites of locoregional failure following mastectomy, which justifies treatment to these regions. While long-term complications are uncommon following locoregional radiotherapy, careful treatment planning is critical to minimize cardiac (and pulmonary) toxicity.

Abstract
Sentinel node (SN) biopsy in breast cancer is still in a crucial stage of evaluation. Many teams have obtained excellent results using this method, with a detection rate always higher than 90% and a false negative rate between 0 and 8%, in prospective series. The main question is to know if lymphadenectomy can now be avoided when the SN is negative. The answer will come from the results of the two ongoing trials comparing sentinel node biopsy to axillary lymphadenectomy. But their results will be available only in two or three years. However, many teams, as at Institute Gustave Roussy, are now applying the technique routinely, because of the excellent results obtained during their learning curve. But there are some methodological differences between teams, which can influence the detection and false negative rates. Thus, several methodological standards remain to be defined. This review enable us to clarify a certain number of questions. Today, SN biopsy can only be performed by trained teams, with prospective evaluation of their results or participation in phase III trials.

Abstract
Before the second half of this century, treatment approaches to breast cancer were radical and disfiguring. In the past four decades, however, multiple prospective randomized trials have made highly significant advances in the management of patients with this disease. These trials have established, in select patients, breast conservation therapy as a primary therapeutic procedure, and radiation therapy as a means to improve local control and survival. This article provides an overview of some of these trials.

Abstract
Cases of recurrence of breast cancer can pose considerable diagnostic and therapeutic challenges for the oncologic team. The prognosis and management decisions are based on knowledge of the true extent of disease. Conventional staging methods, including physical examination, assessment of levels of tumor markers, cross-sectional imaging, and bone scintigraphy, may not reliably demonstrate the extent of disease in all cases. Physical examination and cross-sectional imaging (computed tomography [CT] or magnetic resonance imaging) can be problematic because (a) the sequelae of previous surgery and radiation therapy can be difficult to distinguish from recurrent neoplasms and (b) early metastatic disease (small lesions) can be difficult to distinguish from benign lesions that are too small to characterize. Positron emission tomography (PET) with 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) can help clarify inconclusive findings from physical examination and cross-sectional imaging. FDG PET is more sensitive than CT in detection of lymphatic spread of disease to locoregional and mediastinal nodes. Metastases at distant sites including the lung, bone, and the liver are also readily detected at FDG PET. FDG PET has been proved accurate in restaging cases of recurrent breast cancer and will likely aid in directing therapy in these cases.

Abstract
The long-term follow-up of patients treated with extended radical mastectomy has proved that the internal mammary node (IMN) status is an important prognosticator of breast cancer. Patients with isolated IMN involvement seem to have the same outcome as those with limited axillary disease, and these patients may therefore be overstaged in the TNM system. Sentinel node biopsy (SNB) of IMNs may be an ideal staging procedure, but lymphatic mapping studies demonstrate that data from extended radical mastectomy series cannot be extrapolated to patients suitable for SNB, where the IMN involvement is <5% overall, and around 1% for IMN metastases without axillary disease. Current evidence does not allow internal mammary SNB to be recommended as a standard procedure, but as patients with IMN involvement may benefit from adjuvant systemic treatment, internal mammary SNB should be further studied in this context.

Abstract
PURPOSE To compare patients with visualized sentinel lymph nodes (SLNs) and patients with nonvisualized SLNs, with a focus on variables affecting SLN visualization at preoperative lymphoscintigraphy and on nodal drainage basins as related to tumor location. MATERIALS AND METHODS One hundred thirty-six patients who had breast cancer underwent preoperative lymphoscintigraphy before SLN biopsy. Patients with visualized and nonvisualized SLNs were compared for age; tumor site, size, and histologic findings; injection guidance method; diagnostic biopsy type; interval between biopsy and lymphoscintigraphy; intraoperative identification method; and surgical identification rate. Visualized SLN drainage basins were noted. RESULTS Ninety-nine patients had visualized and 37 had nonvisualized SLNs, without statistically significant differences in tumor site, size, and histologic findings; injection guidance method; diagnostic biopsy type; and interval between biopsy and lymphoscintigraphy. Ninety-nine (73%) of the 136 SLNs were visualized at lymphoscintigraphy; 30 (81%) of the 37 nonvisualized SLNS were identified at surgery. Of the seven SLNs not identified at surgery, five were mapped with radiocolloid only. Patients with nonvisualized SLNs were older than those with visualized SLNs. Eleven (46%) of 24 tumors with internal mammary drainage were in the outer part of the breast. CONCLUSION Patients with and those without visualization differed in age, SLN identification at surgery, and surgical identification method. Nonvisualized status does not preclude axillary metastasis. In older patients with nonvisualized SLNs, blue dye may aid in SLN detection, as compared with isotope-only localization.

Abstract
OBJECTIVE To investigate the feasibility of internal mammary sentinel lymph node biopsy as a method to refine and thereby improve nodal staging in breast cancer. SUMMARY BACKGROUND DATA The internal mammary lymph node status is a major prognostic factor in breast cancer. If positive, prognosis is less favorable. However, staging this regional nodal basin is not performed routinely, thus discarding additional staging information. METHODS In a consecutive series of 256 patients with primary breast cancer, sentinel node biopsy was performed based on lymphoscintigraphy, intraoperative gamma probe detection, and blue dye mapping using 10 mCi (370 MBq) (99m)Tc-nanocolloid injected peritumorally and 0.5 to 1.0 mL Patent Blue V injected intradermally. During surgery, whenever possible, both axillary and internal mammary sentinel nodes were sampled. RESULTS Lymphoscintigraphy showed axillary sentinel nodes in 95% (243/256) and additional internal mammary sentinel nodes in 25.3% (65/256). The overall success rate of axillary sentinel node biopsy was 97% (249/256). Sampling the internal mammary basin, based on the results of lymphoscintigraphy, was successful in 63% (41/65). In three patients a small pleural lesion resulted from staging this basin. This technique revealed internal mammary metastases in 26.8% (11/41). In 7.3% (3/41), internal mammary nodes showed metastatic involvement without accompanying axillary metastases. CONCLUSIONS Internal mammary sentinel node biopsy is feasible without serious additional complications. It improves nodal staging in breast cancer by identifying higher-risk subgroups with internal mammary nodal metastases, which might benefit from altered adjuvant treatment regimens.

Abstract
BACKGROUND Metastases to internal mammary lymph nodes (IMN) may occur in patients with breast cancer and may alter treatment recommendations. The purpose of this study was to identify the frequency of IMN drainage in patients undergoing breast lymphoscintigraphy and sentinel lymph node dissection (SLND). METHODS The combined technique of peritumoral injection of radiocolloid and Lymphazurin blue for SLND was performed on 220 patients. All patients underwent preoperative lymphoscintigraphy before SLND. Lesion location by quadrant included: 110 upper outer (UOQ), 49 lower outer (LOQ), 30 upper inner (UIQ), 24 lower inner (LIQ), and 7 central. RESULTS Drainage to any nodal basin was observed in 184 of 220 patients (84%). IMN drainage was documented in 37 of 220 (17%) of patients. IMN drainage without evidence of axillary drainage occurred in 2 of 220 patients(1%). Drainage to the IMN based on quadrant location of the lesion was as follows: UOQ, 10%; LOQ, 27%; UIQ, 17%; LIQ, 25%; and central, 29%. CONCLUSIONS Internal mammary lymph node drainage shown by breast lymphoscintigraphy is common. Tumors in all quadrants may drain to IMNs, although drainage is significantly more common from quadrants other than the UOQ. Further studies are needed to determine whether lymphoscintigraphy drainage patterns identify patients at the highest risk for IMN metastases who may benefit from radiotherapy.

Abstract
BACKGROUND AND OBJECTIVE Dermal and intraparenchymal (IP) injections of radiocolloid have been used for lymphoscintigraphic identification of the sentinel node (SN) in breast cancer. Because of our institute's extensive experience with dermal and IP lymphoscintigraphy for melanoma and breast cancer, we compared patterns of lymphatic migration after both types of injections to identify any differences in drainage patterns or SN identification. METHODS Lymphoscintigrams (n = 31) after dermal injections in 30 patients with primary cutaneous melanoma on the breast were compared with lymphoscintigrams after IP injections in 97 consecutive patients with breast cancer. In each case, 400 microCi of filtered 99mTc-sulfur colloid was injected in four quadrants around the tumor or in the biopsy cavity. All lymphoscintigrams were reviewed for patterns of migration and SN location. RESULTS Five of 31 (16%) dermal injections demonstrated bilateral axillary migration (n = 3) or a suprasternal SN (n = 2), neither of which was found with IP injections. Conversely, 3 of 97 (3%) IP injections demonstrated direct supraclavicular (n = 2) or costal margin (n = 1) nodes (P = .006), neither of which was found with dermal injections. Low axillary SNs were noted after 26 (84%) dermal and 93 (96%) IP injections (P = .037). The incidence of extra-axillary SNs was 26% (8 of 31) in the dermal group but only 5% (5 of 97) in the IP group (P = .0027). CONCLUSION There is a significant difference in lymphatic drainage and SN localization between dermal and IP lymphoscintigraphy. This finding has implications for injection techniques when lymphatic mapping of the SN is undertaken to stage a breast carcinoma.

Abstract
The promising results of various studies applying different methods of SN biopsy in heterogeneous patient subpopulations, show that sentinel lymph node biopsy is a reliable and minimally invasive method for the determination of the nodal status in breast cancer patients. While multicenter studies for the evaluation of the method's accuracy are still ongoing, future indications and contraindications are discussed. Based on our own experience, we try to give an actual overview of the potentials and problems of sentinel node biopsy in breast cancer. Sentinel node detection was performed in 146 patients with breast cancer stages I-III, consisting of 127pT1/2 tumors and 19pT3/4. All of them underwent standard axillary dissection after SN biopsy. Using the radionuclide method including preoperative lymphoscintigraphy and intraoperative gamma. Probe detection, the detection rate varied in relation to the tumor size between 94% for tumors with a diameter < 1 cm, 85% (1-3 cm), 70% (3-5 cm) and 63% (> 5 cm). The accuracy of the SN-biopsy in the prediction of the nodal status varied also with tumor diameter ranging from 100% for very small tumors (< 1 cm), over 97% (1-3 cm) and 88% (3-5 cm), to 67% (> 5 cm). In the subgroup of patients with pT1-2 tumors (n = 106), 57 patients (53%) showed true negative sentinel nodes, 38 (36%) revealed tumor cells in the H&E staining and an additional 7 patients (7%) solely in the immunohistochemical staining. 4 (4%) of these patients, all of them from the first half of the study period, underwent false-negative SN-biopsy, all of them showing lymphangiosis carcinomatosa and/or extensive infiltration of the metastatic lymph node(s). The results presented show, that in about 50% of early breast cancer patients surgical intervention could potentially be avoided after a negative SN-biopsy, and an additional 5-10% of conventionally nodal negative patients can be found by immunohistochemical examination of the sentinel node. The SN concept is not recommended in clinically nodal positive patients or advanced disease. Potential applications include the evaluation of parasternal lymph nodes and patients with recurrent tumor. Before clinical application, quality control of the medical center and the performing surgeon have to be established potentially including the performance of about 20 procedures under supervision for each surgeon, an individual accuracy of at least 93%, and the possibility of immunohistochemical staining as well as a regular follow-up.

Abstract
PURPOSE To explore the independent prognostic impact of medial hemisphere tumor location in early breast cancer. PATIENTS AND METHODS A comprehensive database was used to review patients referred to the British Columbia Cancer Agency from 1989 to 1995 with early breast cancer. Patients were grouped according to relapse risk (high or nonhigh) and adjuvant systemic therapy received. Multiple regression analysis was used to determine whether the significance of primary tumor location (medial v lateral hemisphere) was independent of known prognostic factors and treatment. RESULTS In the adjuvant systemic therapy groups, medial location was associated with a 50% excess risk of systemic relapse and breast cancer death compared with lateral location. Five-year systemic disease-free survival rates were 66.3% and 74.2% for high-risk medial and lateral lesions, respectively (P <.005). Corresponding 5-year disease-specific survival rates were 75.7% and 80.8%, respectively (P <.03). No significant differences were observed between medial and lateral location for low-risk disease regardless of adjuvant therapy or for high-risk disease with no adjuvant therapy. Local recurrence rates were similar for all risk and therapy groups. CONCLUSION The two-fold risk of relapse and breast cancer death associated with high-risk medial breast tumors may be due to occult spread to internal mammary nodes (IMNs). Enhanced local control, such as with irradiation of the IMN chain, may be one way to reduce the excess risk. Ongoing randomized controlled trials may provide prospective answers to the question of the optimal volume of radiotherapy.

Abstract
BACKGROUND Lymphatic mapping in patients with breast cancer can reveal sentinel lymph nodes that are not located at level I-II of the axilla. Little is known about the clinical relevance of these nodes. METHODS Some 113 consecutive patients with clinical stage T1-3 N0 M0 breast cancer were studied. Based on preoperative lymphoscintigraphy, sentinel node biopsy was performed guided by a gamma probe and patent blue dye. All sentinel nodes that were visible on lymphoscintigraphy were sought. Pathological examination of the sentinel nodes included step-sections and staining with CAM 5. 2. Axillary node dissection was performed regardless of sentinel lymph node status. RESULTS Twenty-one (19 per cent) of 113 patients had sentinel lymph nodes outside level I-II of the axilla, mostly in the internal mammary chain. Twenty-two of the 30 sentinel nodes at these sites were harvested. Three patients had sentinel nodes only outside the axilla. Four other patients had metastases outside the axilla. This changed postoperative treatment in three patients. No postoperative complication occurred. CONCLUSION Sentinel lymph nodes outside level I-II of the axilla were present in 19 per cent of patients with breast cancer in this series. Biopsy of these nodes was technically demanding but was performed without additional morbidity. The clinical impact was limited; treatment changed in only 3 per cent.

Abstract
BACKGROUND Controversy continues to surround the best practice for management of the axilla in patients with early breast cancer (EBC), particularly the clinically negative axilla. The balance between therapeutic and staging roles of axillary surgery (with the consequent morbidity of the procedures utilized) has altered. This is due to the increasing frequency of women presenting with early stage disease, the more widespread utilization of adjuvant chemoendocrine therapy and, more recently, the advent of alternative staging procedures, principally sentinel node biopsy (SNB). The aim of the present review is to critically analyse the current literature concerning the preferred management of the axilla in early breast cancer and make evidence-based recommendations on current management. METHODS A review was undertaken of the English language medical literature, using MEDLINE database software and cross-referencing major articles on the subject, focusing on the last 10 years. The following combinations of key words have been searched: breast neoplasms, axilla, axillary dissection, survival, prognosis, and sentinel node biopsy. RESULTS Despite the trend to more frequent earlier stage diagnosis, levels I and II axillary dissection remain the treatment of choice in the majority of women with EBC and a clinically negative axilla. CONCLUSIONS Sentinel node biopsy has no proven superiority over axillary dissection because no randomized controlled trials have been completed to date. Despite this, SNB will become increasingly utilized due to encouraging results from major centres responsible for its development, and patient demand. Therefore if patients are not being enrolled in clinical trials strict quality controls need to be established at a local level before SNB is allowed to replace standard treatment of the axilla. Unless this is strictly adhered to there is a significant risk of an increase in the frequency of axillary relapse and possible increased understaging and resultant inadequate treatment of patients.

Abstract
A retrospective analysis was conducted to evaluate the incidence of nodal failure in a subgroup of patients who had T1-T2 breast cancer and four or more positive nodes. Sixty-four 5 patients ranging in age from 29 to 73 years (median, 51) received conservative surgery followed by radiotherapy to the breast between November 1980 and May 1995. Adjuvant chemotherapy was administered to 56 patients, 27 of whom were also treated with tamoxifen, which was used alone in 5 patients. Three patients received no adjuvant treatment. Sixty-two patients are evaluable for regional node failure. There were 10 nodal failures, 4 in the axillary and 6 in the supraclavicular regions, in 9 patients, at a median of 56.5 and 27 months, respectively. There was no internal mammary node failure. Median follow-up was 72.6 months. The 10-year probability of developing axillary and supraclavicular failure is 13.9 +/- 7.7% and 10.5 +/- 4.1%, respectively. Prognosis was better for patients with axillary and breast recurrence and worse when relapse was in the supraclavicular region. On the basis of our results and data already published in premenopausal patients, we believe that radiotherapy to the supraclavicular region should be considered in patients with four or more positive axillary nodes, after a complete dissection.

Abstract
The standard surgical treatment of the axilla in patients with early breast cancer is about to undergo a radical change. Although axillary dissection is an excellent procedure for both staging and local control, particularly in the clinically positive axilla, it has considerable morbidity and may understage a significant proportion of patients, because it will usually miss micrometastases that can occur in approximately 10% of 'node negative' patients. An increasing number of patients whose tumours are either non-invasive (ductal carcinoma in situ; DCIS), micro-invasive, tubular cancers or low-grade T1a tumours without lymphovascular invasion may be spared axillary surgery because the risk of axillary disease is 0-3%. Many studies, both prospective trials and large retrospective series, show that axillary radiotherapy alone provides similar local control rates to axillary dissection in patients with clinically negative axillas. Primary treatment of the axilla with radiotherapy alone, however, does not allow appropriate staging. Sentinel lymph node biopsy is being increasingly used in patients with breast cancer to provide this information. When a sentinel node is identified it is equal to or better than axillary dissection for staging the axilla and, if the node is positive, it will help select patients who should then proceed to further axillary surgery or axillary radiotherapy. Although sentinel lymph node biopsy is being rapidly adopted in many centres worldwide, the results of randomized controlled trials are needed before it can be recommended as the standard of care.

Abstract
BACKGROUND Controversy exists regarding internal mammary lymph nodes (IMNs) in the staging and treatment of breast cancer. Sentinel lymph node identification with radiocolloid can map drainage to IMNs and directed biopsy can be performed with minimal morbidity. Furthermore, recent studies suggest that IMN drainage of breast tumors may be underestimated. To gain further insight into the prognostic value of IMNs, we reviewed the outcome of patients in whom the IMN status was routinely assessed. METHODS A retrospective review of 286 patients with breast cancer who underwent IMN dissection between 1956 and 1987 was conducted. RESULTS Median follow-up is 186 months, age was 52 years (range, 21-85 years), tumor size was 2.5 cm, and number of IMNs removed was 5 (range, 1-22); 44% received chemotherapy, 16% endocrine therapy, and 5% radiotherapy. Presence of IMN metastases correlated with primary tumor size (P < .0001) and number of positive axillary nodes (P < .0001) but did not correlate with primary tumor location or age. Overall, the 20-year disease-free survival is significantly worse for the 25% of patients with IMN metastases (P < .0001). In patients with positive axillary nodes and tumors smaller than 2 cm, there was a significantly worse survival (P < .0001) in the patients with IMN metastases. This difference in survival was not seen in women with tumors larger than 2 cm. CONCLUSIONS Patients with IMN metastases, regardless of axillary node status, have a highly significant decrease in 20-year disease-free survival. Treatment strategies based on knowledge of sentinel IMN status may lead to improvement in survival, especially for patients with small tumors. At present, sentinel IMN biopsies should be performed in a clinical trial setting.

Abstract
PURPOSE The elective treatment of internal mammary lymph nodes (++IMNs) in breast cancer is controversial. Previous randomized trials have not shown a benefit to the extended radical mastectomy or elective IMN irradiation overall, but a survival benefit has been suggested by some for subgroups of patients with medial tumors and positive axillary lymph nodes. The advent of effective systemic chemotherapy and potential for serious cardiac morbidity have also been factors leading to the decreased use of IMN irradiation during the past decade. The recent publishing of positive trials testing postmastectomy radiation that had included regional IMN irradiation has renewed interest in their elective treatment. The purpose of this study is to critically review historical and new data regarding IMNs in breast cancer. METHODS AND MATERIALS The historical incidence of occult IMN positivity in operable breast cancer is reviewed, and the new information provided by sentinel lymph node studies also discussed. The results of published randomized prospective trials testing the value of elective IMN dissection and/or radiation are analyzed. The data regarding patterns of failure following elective IMN treatment is studied to determine its impact on local-regional control, distant metastases, and survival. A conclusion is drawn regarding the merits of elective IMN treatment based on this review of the literature. RESULTS Although controversial, the existing data from prospective, randomized trials of IMN treatment do not seem to support their elective dissection or irradiation. While it has not been shown to contribute to a survival benefit, the IMN irradiation increases the risk of cardiac toxicity that has effaced the value of radiation of the chest wall in reducing breast cancer deaths in previous randomized studies and meta-analyses. Sentinel lymph node mapping provides an opportunity to further evaluate the IMN chain in early stage breast cancer. Biopsy of "hot" nodes may be considered in the future to select patients who are most likely to benefit from additional regional therapy to these nodes. CONCLUSIONS Irradiation of the IMN chain in conjunction with the chest wall and supraclavicular region should be considered only for those with pathologically proven IMNs with the goal of improving tumor regional control.

Abstract
The sentinel node concept is valid for penile cancer, melanoma, breast cancer and is probably also applicable to other solid malignancies. Sentinel nodes are the one or two initial nodes in the regional nodal drainage basin encountered by the lymphatic effluent from a tumour, which can be identified with an injection of vital dye or other lymphogogue. Sentinel lymph node dissection (SLND), a minimally invasive procedure with negligible morbidity, has therefore been utilized as an alternative to complete axillary lymph node dissection (ALND) for staging breast cancer. Examination of sentinel nodes provides a focused histopathological assessment of tissue most likely to harbour metastases, providing enhanced staging accuracy with a low false-negative rate. Tumour-free sentinel nodes are predictive of a tumour-free axilla, thereby allowing for the possibility of SLND without ALND and sparing patients the morbidity of ALND. Most of the experience from SLND has been obtained for axillary sentinel nodes. However, sentinel nodes have been identified in nonaxillary sites, such as the internal mammary nodes, but data on SLND for these regions is scarce. The ultimate role of SLND in breast cancer, which may be to identify sentinel-node-negative patients or even those with sentinel node metastases who can safely avoid ALND without sacrificing regional control and possibly gain a therapeutic benefit, cannot be defined before we have the results of large trials that are currently in progress.

Abstract
The aim was to assess the effectiveness of and indications for irradiation of the internal mammary chain (IMC) in the treatment of breast cancer based on a review of the literature. A computerized literature search was performed of the MEDLINE database from 1966 to March 1998. The data retrieved were ranked into levels of evidence as per convention. There was no Level I evidence found. Six randomized controlled trials and nine retrospective series were found pertaining to early stage breast cancer. Although some retrospective data suggested that IMC irradiation improved survival in mediocentral and axillary node-positive tumours, this was not supported by the randomized data. Two randomized trials were identified in high risk operable breast cancer. One of these showed a survival advantage to post-mastectomy irradiation, but the contribution of IMC irradiation to this could not be delineated. Based on the best current evidence, there is no advantage to elective IMC irradiation. The only indication is for positive IMC nodes where the management aim is palliative. The ongoing EORTC randomized trial may provide the definitive answer.

Abstract
Internal mammary node involvement in early breast cancer is a prognostic factor of uncertain significance. This paper addresses isolated regional recurrence at this site following breast conservation radiotherapy. A case is presented of a woman who developed an internal mammary recurrence after lumpectomy and breast irradiation. This recurrence was diagnosed as a bone metastasis, a common mistake which may lead to suboptimal management. The true incidence of regional recurrences in the internal mammary nodes has been underestimated and their clinical significance has not been appreciated. Salvage procedures for local control and long-term cure are likely to be successful if the diagnosis is made before distant metastases have occurred and a lengthy period has elapsed since initial treatment was given. The role of reirradiation should be considered as the tissues at this site will generally tolerate a second course of radical radiotherapy given more than 10 years after the first.

Abstract
Postmastectomy radiotherapy decreases threefold the risk of locoregional recurrences according to the results of many randomized trials and overviews. This risk is mainly related to the number of involved axillary nodes (ie, about 25%, 35%, and 55% at 10 years when 1 to 3, 4 to 9, and 10 or more nodes are involved). In contrast, at 10 years, fewer than 15% of patients with negative axillary nodes relapse locally. The effect of postmastectomy radiotherapy on distant metastases and overall survival is a controversial issue. On the one hand, results are compatible with the existence of a mechanism of secondary dissemination generated from locoregional tumor nests. The beneficial effect of radiotherapy may be observed in the absence or presence of adjuvant systemic treatment. On the other hand, a deleterious late toxic, mainly cardiac, effect of radiation has also been shown. This point emphasizes the importance of radiation technique and quality to obtain a positive balance in terms of overall survival.

Abstract
BACKGROUND This prospective study was performed to ascertain the added benefit of lymphoscintigraphy to a standard method of intraoperative lymphatic mapping and sentinel node biopsy for breast cancer. METHODS Patients with invasive breast cancer were injected with 99mTc sulfur colloid prior to sentinel node biopsy; preoperative lymphoscintigraphy was then performed in half of the patient population. RESULTS Sentinel node identification was possible in 45 of 50 patients (90%). All 14 patients (31%) with axillary nodal metastases had at least one histologically positive sentinel node (0% false negative rate). Lymphoscintigraphy revealed sentinel nodes in 17 of the 24 patients (70.8%) imaged. All 17 of these patients had one or more axillary sentinel nodes identified using intraoperative lymphatic mapping. In addition, 5 of 7 patients with a negative preoperative lymphoscintogram had an axillary sentinel lymph node(s) identified intraoperatively. None of the tumors showed drainage to the internal mammary lymph node chain by lymphoscintigraphy despite the fact that there were 5 patients with inner quadrant tumors. There was no significant advantage with respect to sentinel lymph node localization (91.7% versus 88.5%, P = not significant) or false negative rate (0%, both groups, P = not significant) in the group undergoing preoperative lymphoscintigraphy when compared with the patients in whom lymphoscintigraphy was not performed. CONCLUSIONS Preoperative lymphoscintigraphy adds little additional information to intraoperative lymphatic mapping, and its routine use is not justified.

Abstract
AIMS Lymphatic mapping and sentinel node (SN) biopsy in breast cancer contribute to more accurate staging, while using less invasive techniques. The aim of this study is to improve the accuracy and feasibility of this concept, increasing the identification rate of the SN, by using an alternative technique. METHODS In 70 unselected patients with primary breast cancer, of whom 51% had undergone previous excisional biopsy, lymphatic mapping was performed using 10 mCi (370 MBq) 99mTc-nanocolloid peritumorally, combined with an intradermal blue dye tracer. RESULTS Lymphoscintigraphy showed one or more SN in 97% and harvest of the SN was possible in all patients (identification rate 100%). Axillary metastases were found in 39%. Sensitivity of the SN biopsy was high, both after primary surgery (93%) and after previous surgery (100%). Internal mammary lymph node biopsy following lymphatic mapping was attempted in all 24 patients (34%) with parasternal SN visible on the scan and was successful in 15 patients, revealing metastatic involvement in five patients. CONCLUSIONS We conclude that SN biopsy, using a higher dose of peritumoral radiocolloid tracer, combined with intradermal blue dye tracer, increases feasibility in breast cancer, making this concept applicable for all patients with primary breast cancer.

Abstract
We reviewed the literature regarding internal mammary lymph node metastasis in the management of breast cancer. Internal mammary dissection or radiotherapy provides no survival advantage in breast cancer patients. However, internal mammary nodal metastasis is an important independent prognostic factor. Patients with such metastases are candidates for systemic adjuvant hormonal therapy and/or chemotherapy. Moreover, in patients with histologically confirmed internal mammary metastases, irradiation of the nodes is appropriate for local control. Noninvasive techniques, such as internal mammary lymphoscintigraphy, parasternal sonography, computed tomography, and magnetic resonance imaging, are not satisfactory for the practical diagnosis of internal mammary metastasis. At present, biopsy of the internal mammary nodes in the first and second intercostal spaces is indicated for assessing nodal status and planning treatment.

Abstract
The diagnosis and treatment of breast cancer in Australia has changed in response to new technologies and cultural influences which have emphasized the importance of psychological and social aspects of breast cancer. In this review article, recent developments are examined in relation to current surgical practice. Changes in the incidence of breast cancer, the effect of mammographic screening on the outcome of treatment, the increasing use of breast-conserving surgery, the timing of surgery in relation to the menstrual cycle and the importance of risk factors for breast cancer are all considered. Breast cancer is a potentially curable disease. Early detection and conservative surgery provide a framework for disease control.

Abstract
A total of 370 patients with metastatic breast, carcinoma who had been followed at Hacettepe Oncology Department between 1980 and 1991 were retrospectively analyzed for the factors influencing the distribution of metastases and survival. Median age was 47 years. Radical or modified radical mastectomies were performed in 199 (53.8%). Infiltrative ductal carcinoma was the most common pathologic subtype (69.4%). In 191 patients who were evaluated for estrogen receptor (ER) status, 101 (52.9%) were positive and 90 (47.1%) were negative. The distribution of first metastases did not differ between the soft tissue, bone, and visceral sites. The second, third, and fourth metastases were more common in visceral sites (p < 0.05). ER and menopausal status did not affect distribution. Mortality rate was significantly lower in the group having the first metastasis to the bone (p < 0.05). Of interest, first metastases were predominantly found in visceral sites in patients having radical or modified radical mastectomies (p < 0.05). Response to therapy, presence of initial metastases, axillary status, and age were the important factors influencing the overall survival in univariate analysis, whereas response to therapy, ER status, age, and presence of initial metastases were the important factors according to the multivariate analysis.

Abstract
The management of regional lymph node metastases in breast cancer and gastric cancer is reviewed. Regional lymph node metastasis is a critical prognostic factor in these diseases, but there is an apparent discrepancy in the efficacy of regional lymph node dissection between them. A number of prospective randomized clinical trials have demonstrated that regional lymph node dissection improves the regional control of breast cancer, but does not improve the survival. On the other hand, only retrospective or prospective comparative studies have shown that extended lymph node dissection significantly improves the survival in gastric cancer. Although the discrepancy in the regional lymph node dissection between breast and gastric cancers has been explained by differences in their biological behaviors, caution must still be exercised in drawing conclusions from these norandomized studies.

Abstract
BACKGROUND The internal mammary lymph nodes (IMN) have received little attention in recent years, yet are a well-documented site of metastasis and a major prognostic factor in early-stage breast cancer. METHODS/RESULTS Ten-year follow-up of the final 195 patients treated by extended radical mastectomy (ERM) in this practice (selected largely on the basis of medial tumor location, and comprising 15% of all patients treated from 1965 to 1978) found IMN+ in 24% of all cases: 36% of AX+ versus 18% of AX- patients (p = 0.0023). In a multivariate analysis, the disease-free survival impact of IMN+ (p = 0.004) was second only to axillary node involvement (p < 0.0005), and surpassed tumor size (p = 0.077). IMN+ was equally frequent for tumors less than, or greater than, 2 cm (24%), and was not significantly related to patient age. Among AX- patients, there was a twofold greater risk of recurrence or death at 10 years for IMN+ than for IMN-. Among T1N0 patients, 19.6% were IMN+. CONCLUSIONS Failure to consider IMN status in the steadily enlarging cohort of T1N0 breast cancers may result in the undertreatment of a significant proportion of stage I patients. Systemic adjuvant therapy should be considered for T1N0 patients with central or medial tumors.
