Proliferating cell nuclear antigen labeling index and p53 expression predict outcome for breast cancer patients with four or more lymph node metastases.

In general, extensive lymph node metastasis indicates poor prognosis in breast cancer. Nevertheless, some patients with this condition survive for a long time without recurrent disease. This study involved 112 breast cancer patients with four or more lymph node metastases and without distant metastasis who underwent surgery. p53 expression was associated with shorter overall and disease-free survival. High PCNA labeling index was associated with shorter overall disease-free survival. p53-negative and low-PCNA patients survived much longer than p53-positive and high-PCNA patients. This study showed that p53-negative or low-PCNA index patients have relatively good prognoses despite extensive lymph node metastasis.

[Variants and stages of regional lymph nodes sclerosis in lymphedema].

The inguinal lymph nodes of patients with primary lymphedema of lower extremities were investigated by light microscopy. It was found that sclerotization of regional lymph nodes can begin with both cortical and medullary parenchyma. Different stages of this process in lymph nodes were distinguished. These stages depend on the duration of the illness and the zone of organ where the first signs of sclerotization were observed. Small islands of lymphoid parenchyma were found in even well advanced sclerosis lymph nodes, and this allows to assume possibility of full regeneration of all structure of these organs when lymph circulation is normalized.

Dynamic changes in the lymphocyte subpopulations of pig uterine lymph nodes.

Cell subpopulations in local lymph nodes draining the uterine tissue of non-pregnant and pregnant pigs were examined by one- and two-colour immunofluorescent staining and flow cytometry using a panel of monoclonal antibodies to pig leucocyte cell surface antigens. Significant changes were observed in the T and B lymphocyte subpopulations and in a subpopulation of non-T or B cells. Activation of lymphocytes in the uterine lymph nodes during cycling in non-pregnant gilts suggests a role for the local immune system in the normal physiology of the uterus. In non-pregnant sows there was evidence of an increase in the CD4/CD8H ratio and in the proportion of B cells in the uterine nodes when compared to gilts with no prior reproductive experience. Pregnancy was shown to induce further dramatic changes in the uterine lymph nodes with an escalation in the proportion of B cells from 48% to 88% and a further increase in the CD4/CD8H ratio. For the first time in swine, low-level CD2 expression is reported on a subpopulation of B cells which are activated during pregnancy. These results provide evidence that the local uterine immune system in pigs plays a role in reproduction and perhaps in the maintenance of normal pregnancy.

Methodological questions in sentinel lymph node analysis in breast cancer patients.

BACKGROUND: The sentinel lymph node (SLN) procedure has been proposed to women with breast cancer with clinically negative axillary lymph nodes, in order to avoid conventional axillary lymph node dissection and its associated side-effects. Methodological aspects of the validation of the SLN procedure are questioned here. MATERIALS AND METHODS: The results of relevant published studies are reviewed, with emphasis on pathological techniques. The ability of the SLN procedure to diagnose lymph node metastases, the extent to which axillary lymph node dissection contributes to treatment, apart from identification of the stage, and the effect of a modified staging procedure on treatment strategies are analyzed. RESULTS AND CONCLUSION: Both the sensitivity and the negative predictive value of the SLN procedure are overestimated if the probability of missing lymph node metastases is not taken into account, even when a complete axillary dissection is performed as a control. The SLN strategy and its effects on staging and treatment cannot be evaluated by comparison with conventional axillary lymph node dissection in a one-arm study but require carefully designed randomized trials.

The lymph node in chronic lymphocytic leukemia.

Lymph nodes were examined from 41 cases of typical chronic lymphocytic leukemia (CLL). Degree of immaturity was graded as absent to minimal (Grade I), moderate (Grade II) and marked (Grade III). A moderate degree of immaturity was found in the lymph node in 14 of 41 cases even though the cells seen on the initial bone marrow and peripheral blood smears obtained from these patients were essentially all mature. The morphology of these nodes could be confused with poorly differentiated lymphocytic or mixed lymphocytic-histiocytic lymphoma in terms of the degree of immaturity present. A marked degree of immaturity present. A marked degree of immaturity was found in 5 cases; the morphology of these cases resembled histiocytic lymphoma. In the remaining 22 cases immaturity was essentially absent. The morphology of these cases was similar to that of diffuse well differentiated lymphocytic lymphoma. Our studies suggest that a moderate degree of immaturity in the lymph node of patients with CLL does not indicate that these patients will have a marked shortening of their survival.

Sentinel lymph node biopsy in head and neck squamous cell carcinoma.

OBJECTIVES/HYPOTHESIS: Sentinel lymph node biopsy is a minimally invasive method to stage the regional lymphatics that has revolutionized the management of patients with intermediate-thickness cutaneous melanoma. Head and neck surgeons have been encouraged by the accuracy of sentinel lymph node biopsy in cutaneous melanoma and have applied the technique to patients with head and neck squamous cell carcinoma (HNSCC). The objectives of the study were 1) to study the feasibility and accuracy of sentinel lymph node biopsy as a method to stage the regional lymphatics in HNSCC and 2) to determine whether there are qualitative differences between the cutaneous and mucosal lymphatics that would affect the technique used in HNSCC. STUDY DESIGN: Two methods of investigation were employed: a prospective laboratory study using a feline model for sentinel lymph node biopsy and a retrospective review of patients who received lymphoscintigraphy before neck dissection and intraoperative identification of the sentinel lymph node. METHODS: Lymphoscintigraphy and a gamma probe were used in four felines to study the kinetics of technetium-labeled sulfa colloid (Tc-SC) in the mucosal lymphatics. In the second part of the feline study, eight subjects were studied intraoperatively. Tc-SC and isosulfan blue dye were used to study the injection technique for the mucosal lymphatics and to determine the time course of the dye and Tc-SC to the sentinel lymph node. In Part II of the present study, a retrospective review of 33 patients with HNSCC was conducted. Twenty patients (stage N0) whose treatment included elective neck dissection were studied with preoperative lymphoscintigraphy and underwent intraoperative identification of the sentinel lymph node to determine the accuracy and feasibility of sentinel lymph node biopsy. Eight patients with palpable neck disease and five patients with recurrent or second primary disease whose previous treatment included neck dissection were also studied with lymphoscintigraphy before neck dissection. RESULTS: In the feline study, both Tc-SC and isosulfan blue dye traversed the lymphatics rapidly, appearing in the sentinel lymph node in less than 5 minutes. Modification of the injection technique used for cutaneous melanoma was required to depict the sentinel lymph node of the base of tongue. In the human study, the sentinel lymph node was accurately identified in 19 of 20 (95%) N0 patients. On average, 2.9 sentinel lymph nodes (range, 1-5) were identified in 2.2 (range, 1-4) levels of the neck. Sentinel lymph nodes were bilateral in 4 of 19 patients. When the sentinel lymph node was identified, it accurately predicted the pathological nodal status of the regional lymphatics. Three of 20 patients had cervical metastases, and the sentinel lymph node was identified in 2 of 3 patients with pathologic nodes (pN+). Focal areas of radiotracer uptake were identified in seven of eight patients with palpable disease. These areas corresponded to the level with palpable disease in four patients. The lymphatics delineated by lymphoscintigraphy in the five patients with previous neck dissection were outside the levels that had been dissected. Lymphoscintigraphy depicted collateral patterns of lymphatic drainage. CONCLUSIONS: Sentinel lymph node biopsy is technically feasible and is a promising, minimally invasive method for staging the regional lymphatics in patients with stage N0 HNSCC. Lymphoscintigraphy alone may determine the levels that require treatment in patients with disrupted or previously operated cervical lymphatics.

Prognosis of node-positive breast cancer patients who underwent parasternal lymph node biopsy during surgery followed by doxorubicin- or mitoxantrone-containing adjuvant chemotherapy.

The authors examined the survival rates of 60 patients with breast cancer who underwent parasternal lymph node biopsy during surgery with axillary lymph node dissection and had histologically confirmed axillary node metastasis followed by adjuvant doxorubicin- or mitoxantrone-containing combination chemotherapy to ascertain whether administration of anthracycline or its analogue improved the prognosis of both axillary and parasternal node-positive patients. The overall survival rate (OS) for the parasternal node-positive patients (n=13, 21.7%) was 30.6%, and relapse-free survival rate (RFS) fell to 0% at the 104-month follow-up. Although the survival rate for all axillary node-positive patients was similar to those in previous reports, the OS and RFS for both axillary and parasternal node-positive patients were significantly worse than that for axillary node-positive and parasternal node-negative patients, despite treatment with adjuvant doxorubicin- or mitoxantrone-containing combination chemotherapy. Other intensive adjuvant treatment strategies are needed to reduce distant metastases for high-risk breast cancer patients having both axillary and parasternal nodes positive.

Primary plasmacytoma of lymph nodes.

Primary plasmacytoma of the lymph nodes is very rare, and there are fewer than 20 reported cases. These cases appeared to have a better prognosis than other extramedullary plasmacytomas, with rare recurrence and no progression to myeloma after treatment. To better characterize the clinicopathological features and the pathogenesis of primary plasmacytoma of the lymph nodes, we reviewed our consultation files and retrieved seven such cases. The age of presentation ranged from 39 to 76 years (median age, 59 years), with three women and four men. The clinical follow-up varied from 1 to 14 years. All patients presented with enlarged lymph nodes and had an indolent clinical course, except for one patient with slow progression and increasing numbers of bone marrow plasma cells. Five patients were treated with excision only and two with excision and chemotherapy. None of the patients had recurrence or developed multiple myeloma. All cases showed immunoglobulin light chain restriction, four with monotypic lambda and three with monotypic kappa. One patient had extensive nodal amyloid deposition. Four cases had monoclonal heavy chain expression, three with monoclonal immunoglobulin (Ig) G and one with monoclonal IgM. All cases were negative for CD20 and CD43, and six cases expressed CD79a. Overexpression of p53 and bcl-2 was not detected by immunostaining in any of the cases. Epstein-Barr viral (EBV) RNA was not detected in all seven cases by in situ hybridization, and no Kaposi's sarcoma-associated herpesvirus (KSHV) DNA sequences were detected by polymerase chain reaction in five cases. Our results confirm a more favorable outcome and rare progression to multiple myeloma in primary nodal plasmacytomas after excision or chemotherapy. The results of oncoprotein and viral studies suggest that the pathogenesis of primary nodal plasmacytoma may not be due to bcl-2- and p53-associated changes or viral-induced changes by EBV and KSHV.

Lymph node metastasis in cancer of the middle-third stomach: criteria for treatment with a pylorus-preserving gastrectomy.

A retrospective study was conducted to establish the criteria for performing a pylorus-preserving gastrectomy. This study was performed on 491 patients who had cancer of the middle-third stomach and had been curatively treated with a distal gastrectomy. The incidence of node metastasis for each lymph node station (the group of regional lymph nodes which have been anatomically defined and classified by the Japanese Classification of Gastric Carcinoma) was evaluated with reference to the depth of invasion, tumor size, and circumferential location, to show any significant correlations with an increase in tumor diameter or in the depth of tumor invasion. The benefits of resecting each station was then evaluated based on the incidence of metastasis to each station and the rate of long-term survivors among those with metastasis to each station. The benefit was substantial for the lymph nodes along the lesser curvature, along the right gastroepiploic artery, and at the base of the left gastric artery, while the advantages were almost negligible for the suprapyloric nodes and right paracardial nodes. In conclusion, carcinoma that fulfills either of the following conditions may thus be indicated to undergo a pylorus-preserving gastrectomy: (i) restricted to a depth of m or sml, (ii) a depth of sm2 or mp with a diameter of less than 2cm, (ii) a depth of sm2 or mp and located in the greater curvature.

Management of malignant melanoma of the head and neck using dynamic lymphoscintigraphy and gamma probe-guided sentinel lymph node biopsy.

BACKGROUND: The sentinel lymph node (SLN) biopsy is revolutionizing the surgical management of primary malignant melanoma. It allows accurate nodal staging, and targets patients who may benefit from regional lymphadenectomy and systemic therapy; however, its use in the management of head and neck melanoma has not been widely accepted. METHODS: A retrospective review of patients treated for clinical stages I and II malignant melanoma of the head and neck with dynamic lymphoscintigraphy and gamma probe-guided SLN biopsy. RESULTS: Fifty-eight patients (47 male and 11 female) were identified. Primary melanoma sites included the scalp (21), ear (8), face (13), neck (15), and eyelid (1). Primary tumor staging was T2 (11), T3 (24), and T4 (23). Dynamic lymphoscintigraphy visualized SLNs in 57 patients (98.3%). In 43 cases (75%) a single draining nodal basin was identified, and in 14 cases there were multiple draining nodal basins. Sentinel lymph nodes were successfully identified in 72 (96%) of 75 nodal basins. Positive SLNs were identified in 10 patients (17.5%). Sentinal lymph node positivity by tumor staging was T3, 16.7% and T4, 27.3%. Completion lymphadenectomy revealed residual disease in 3 patients (30%). Relapse occurred in 10 (21.3%) of the 47 patients with negative SLN biopsy results and 7 (70%) of those with positive results. CONCLUSIONS: Gamma probe-guided SLN localization in the head and neck region was successful in 96% of draining nodal basins. It can target regional lymphadenectomy in patients who may benefit from regional nodal dissection.

Can Melan-A replace S-100 and HMB-45 in the evaluation of sentinel lymph nodes from patients with malignant melanoma?

The sentinel lymph node (SLN) biopsy has become an increasingly important procedure used in the primary staging of malignant melanoma. However, micrometastases in a lymph node can be easily missed on routine H&E-stained sections. Therefore, S-100 and HMB-45 IHC stains are standardly performed on grossly negative SLNs for detection of metastatic melanoma. Each of these IHC markers, however, is not ideal. The authors investigated whether the newer IHC marker Melan-A would improve the detection of metastatic melanoma in SLN biopsies. Forty lymph nodes previously diagnosed with metastatic melanoma were retrospectively evaluated for S-100, HMB-45, and Melan-A expression. In addition, 42 SLN biopsies for metastatic melanoma detection were prospectively collected and evaluated for S-100, HMB-45, and Melan-A expression. All lymph nodes with metastatic melanoma from the retrospective study demonstrated S-100 reactivity. Five of the lymph nodes with metastatic melanoma from the retrospective study failed to express either HMB-45 or Melan-A, all of which displayed a desmoplastic morphology. One of the metastases positive for S-100 and HMB-45 failed to show reactivity with Melan-A (3%). The prospective study found 10 lymph nodes from 42 cases to be positive for metastatic melanoma, which were positive for S-100 (100%). Nine of the involved lymph nodes were positive for HMB-45(90%), and nine were positive for Melan-A (90%). Melan-A, although very specific, cannot replace the use of S-100 and HMB-45 for the detection of metastatic melanoma in SLNs. It can, however, substitute for HMB-45 with equally good results.

Expression of tyrosinase, MIA and MART-1 in sentinel lymph nodes of patients with malignant melanoma.

BACKGROUND: Regional lymph node status is an important predictor of survival in patients with malignant melanoma. Mapping of sentinel lymph nodes using sensitive molecular techniques has recently been introduced. Malignant melanoma is heterogeneous in terms of its biological, immunological and metastatic properties, and melanoma cells exhibit a polymorphous expression of tumour markers. Thus, assays that include multiple markers appear to be more sensitive than single-marker assays. OBJECTIVES: To characterize the molecular profiles of melanoma cells in sentinel lymph nodes employing the mRNA expression of tyrosinase, MIA and MART-1 as markers. METHODS: Samples of sentinel lymph nodes from 17 melanoma patients and 18 control nodes from non-melanoma patients were assayed by reverse transcriptase-polymerase chain reaction, using specific primers for each marker. RESULTS: We found that both tyrosinase and MIA expression were sensitive indicators of micrometastases in sentinel lymph nodes that were negative on routine histopathological examination, and that the finding of micrometastases expressing MART-1 in sentinel lymph nodes was negatively correlated with overall survival. CONCLUSIONS: Characterization of the molecular profiles of melanoma cells constitutes a valid means of detecting metastatic melanoma cells in sentinel lymph nodes, and of predicting the survival of melanoma patients.

Spectrum of morphologic changes of lymph nodes in HIV infection.

Cervical lymph nodes biopsies from 31 HIV positive patients (with or without AIDS) were studied by histologic methods and immunohistochemistry (StreptABC staining of paraffin sections) to identify cellular and extracellular matrix components. The results were the following: (1) the biopsies were included in the stages of follicular hyperplasia without fragmentation FH-FF (4 cases); follicular hyperplasia with follicular fragmentation FH + FF (16 cases); follicular involution FI (6 cases) and diffuse pattern DP (5 cases); (2) the most important alteration was the germinal centers disruption due to follicle lysis, which began in the light zone; (3) there was coincidence between intrafollicular hemorrhages and segmental hyaline mycroangiopathy; (4) during the progression of the disease occurred; (a) an increase in the number of mast cells, CD68+ and Mac 387+ macrophages; (b) a diffuse augment of collagen III, elastic fibers, laminin, fibronectin and proteoglycans; (c) maintenance of Factor VIII-related antigens in the vascular endothelial cells, with decrease in the expression of Ulex-Europeus I lectin. Follicular hyperplasia (FH - FF or FH + FF) was the most common histologic pattern recognized in the lymph nodes of patients without AIDS and follicular involution and difuse pattern were seen in those who had AIDS. The results indicate that the lymph node biopsies may provide important information about the evolutive stage of the disease and its prognosis.

Lymphadenectomy in gastric cancer: influence on prognosis of lymph node count.

To better understand the role of the number of lymph nodes retrieved on long-term outcome of gastric cancer treatment, 154 patients who had undergone curative resection, with dissection of >15 nodes were retrospectively studied. Dissection of perigastric and extraperigastric lymph nodes, defined as 'extended' (>26 nodes dissected) in 39 cases and 'limited' (< or = 26 nodes dissected) in 115 cases, was performed. A total of 3479 lymph nodes (mean 22.6 per specimen), were dissected and of these 721 showed metastases. A mean of 8.1 lymph node metastases, per metastatic case, was found. Regression analysis showed no independent factor associated with the extent of lymphadenectomy. Depth of wall invasion (p=0.000) and histological growth pattern (p=0.044) were independently associated with the number of lymph nodes involved (pN0, pN1 1-7, pN2 >7). The cumulative 5-year survival rate was 47% in patients without lymph node metastases; 29% in those with 1-7 nodes involved and 17% in those with >8 nodes involved (p=0.002). Receiver operating characteristic (ROC) curve analysis, in 65 nodenegative cancer cases, demonstrated an area under the curve for vital status (alive or dead) of 0.602 (95% CI: 0.473 - 0.721). All node-negative cases with a number equivalent to or exceeding the cutoff point of 23 nodes were alive. ROC analysis showed 11 to be the cutoff number of metastasized lymph nodes in correlation with vital status. Almost all those patients in whom the number of positive nodes was equivalent to, or exceeded the cutoff point had died (area under the ROC curve 0.633; 95% CI: 0.524 - 0.733). ROC analysis showed that the cutoff lymph node ratio, in relation to vital status, was 0.33. The majority of patients at or above this cutoff point had died (area under ROC curve 0.682; 95% CI: 0.574 - 0.776). Multivariate survival analysis showed that lymph node ratio was the only independent prognostic factor (p=0.001). The present findings suggest that, in lymphadenectomy with at least 15 nodes, the number and status of regional nodes dissected, irrespective of the location, provide reliable prognostic information on curatively resected gastric carcinomas.

[Optimal lymph node dissection for carcinoma of the biliary tract].

To clarify the optimal lymph node dissection for carcinoma of the biliary tract, we analyzed the mode of lymphatic spread in 86 resected cases with carcinoma of the gallbladder and 139 with carcinoma of the extrahepatic bile duct, and investigated long-term results after resection based on the degree of lymph node metastasis. Of the 86 patients with carcinoma of the gallbladder, 62 (72.1%) had lymph node metastasis. Patients with m and mp tumors (n = 9) had no lymph node metastasis, whereas ss tumors (n = 13) had 23.1% lymph node metastasis. Those with se, si tumors (n = 64) had greater lymph node involvement (92.2%). In 4 patients with advanced carcinomas (ss or more) who survived more than 5 years, only one (limited to periportal lymph nodes) of them had lymph node metastasis. Of the 139 patients with carcinoma of the extrahepatic bile duct, 58 (41.7%) had lymph node metastasis. There was no lymph node metastasis in 15 patients with m or fm tumors. The frequency of metastasis in the ss (n = 39) and se, si (n = 85) tumors was 17.9% and 60.0%, respectively. Twenty-four patients with advanced tumors survived more than 5 years. Curative resection was achieved in all 24 and lymph node metastasis was n0 in 19, n1 in 4 and n2 in 1 patients. Satisfactory long-term result can be achieved in carcinoma of the biliary tract after resection when lymph node metastasis is limited to nodes in the hepatoduodenal ligament. In view of our surgical results and the lymphatic drainage system of the biliary tract, systemic dissection of the regional lymph nodes, including periportal, posterior pancreato-duodenal, and celiac nodes, is necessary in patients with N0-N2 (limited to lymph nodes in the hapatoduodenal ligament) tumors in whom it contributes to good prognosis.

Prognostic value of the number of metastatic lymph nodes in gastric cancer with radical surgery.

To evaluate the effectiveness of extended lymph node dissection in gastric cancer, the relationship between the number of lymph nodes with metastasis and the long-term outcome was studied retrospectively in 761 patients who underwent curative resection with extensive lymph node dissection. The cumulative 5-year survival rate was 85.8% in patients without lymph node metastasis, 60.2% in those with 1-4 lymph nodes, 35.6% with 5-10 nodes, and 12.3% with 11 or more nodes involved. Concerning N2 or N3 patients in whom metastatic lymph nodes would have remained without extensive dissection, the 5-year survival rate was 70.5% in those with 1-4 lymph nodes involved and 44.0% with 5 or more lymph nodes involved when no serosal invasion was observed. It was 38.5% with 1-4 lymph nodes and 5% with 5 or more lymph nodes involved when serosal invasion was observed. These results suggest that extensive lymph node dissection is effective in gastric cancer patients without serosal invasion and, when only a few lymph nodes are involved, also in those with serosal invasion. However, it is not considered to be effective in patients with serosal invasion and metastasis to many lymph nodes. Combination therapies are thought to be required in such patients.

ADASP recommendations for processing and reporting of lymph node specimens submitted for evaluation of metastatic disease.

It is well known that different pathologists in different laboratories follow different protocols for the processing and examination of these specimens. There is also extensive literature (some of which is summarized in the references appended to the present report) on the likelihood of identifying metastases of varying sizes with different methods of preparation, as well as on the clinical significance of this identification, which varies not only from site to site but also from report to report on the same site. The Association of Directors of Anatomic and Surgical Pathology (ADASP) has reviewed this literature as well as the personal experience of its own members to present a set of recommendations for lymph node biopsies, lymph node dissections, sentinel node biopsies, lymph node fine needle aspiration (FNA) and core needle biopsies. It should be noted that these recommendations are intended specifically for lymph nodes being studied for metastatic neoplasms, and are not intended to apply to lymph nodes being evaluated for lymphoma, infections, and other disease processes. They are, however, formulated generically enough to apply regardless of whether the primary tumor is a carcinoma of the breast, carcinoma of the prostate, melanoma, or any other malignant, potentially metastasizing tumor. The Association has published numerous documents with recommendations for reporting surgical pathology specimens involving particular organ sites (for example, breast, pancreas, thyroid, etc.) However, the Association has not yet considered the generic question of dealing with lymph node specimens in which the intent is to search for and document the presence of metastatic disease. We are also unaware of guidelines for pathologists published by any other organization on this subject.

Sentinel lymph node biopsy in patients with male breast carcinoma.

BACKGROUND: Sentinel lymph node biopsy (SLNB) is now a widely implemented technique for evaluating the axilla in women with early stage breast carcinoma. Men who develop breast carcinoma are at similar risk as their female counterparts of developing the morbidities related to axillary dissection. SLNB is aimed at preventing these morbidities. In this study, the authors evaluated the role of SLNB in the treatment of men with early stage breast carcinoma. METHODS: Among the 1692 patients who underwent SLNB at the Memorial Sloan-Kettering Cancer Center, 16 men with breast carcinoma were identified. The charts and records of these 16 patients were reviewed retrospectively. RESULTS: The mean patient age was 57.2 years. The mean tumor size was 1.3 cm. In 15 of 16 patients (93.75%) and in all patients with T1 tumors, one or more sentinel lymph nodes were successfully identified. SLNB failed in one patient, who had a T2 tumor (3 cm). Ten of the 15 patients had negative sentinel lymph nodes (66.7%). Four of these patients had no additional lymph nodes removed, whereas six patients had additional lymph nodes removed, all of which were negative. Two patients (13.3%) had positive sentinel lymph nodes on frozen-section analysis and underwent immediate completion axillary dissection: Both had additional positive lymph nodes. Three patients (20.0%) had positive sentinel lymph nodes on further sectioning or immunohistochemistry, and two patients underwent completion axillary dissection: Neither patient had additional positive lymph nodes. The third patient had one immunohistochemically positive lymph node and did not undergo completion axillary dissection. CONCLUSIONS: SLNB for patients with breast carcinoma was as successful in men as it has been shown to be in women and may be offered as a management option to men with early stage breast carcinoma by surgeons who are experienced with the technique.
