    Sentinel lymph node biopsy (SLNbx) is the standard of care for staging of breast cancer. Patients with a negative sentinel lymph node biopsy (SLNbx) do not undergo axillary lymph node dissection (ALND) or regional nodal irradiation (RNI). However, if a patient has a positive sentinel lymph node biopsy (SLNbx), then axillary lymph nodal dissection (ALND) is the standard treatment. Recent studies, notably the Z-0011 and MA-20 trials, have demonstrated that omission of axillary lymph nodal dissection (ALND) did not decrease overall survival. MA-20 demonstrated that inclusion of regional nodal irradiation (RNI) in addition to axillary lymph nodal dissection (ALND) did increase survival when compared to axillary lymph nodal dissection (ALND) without regional nodal irradiation (RNI). Ongoing studies are randomizing patients to axillary lymph nodal dissection (ALND) or regional nodal irradiation (RNI) after a positive sentinel lymph node biopsy (SLNbx).

    Breast cancer is the most frequent cancer of women in western countries. There are one million new cases per year in the world which represents 22% of all female cancers, and more than 370.000 deaths due to breast cancer per year (14% of cancer mortality). More than half of breast cancers are associated with axillary nodal involvement. Post-operative radiation therapy (XRT) is a crucial part of locoregional treatment in axillary nodal involvement breast cancer owing to a 15-years risk reduction of locoregional recurrence of 70% and to a 5.4% risk reduction of specific mortality. In 3D-conformal irradiation in such breast cancers, target volumes are chest wall when mastectomy was performed or breast and boost of tumor bed in case of breast conservative surgery, and supra-clavicular and/or axillary and/or internal mammary node areas. The main organs at risk are ipsilateral lung, heart and brachial plexus. The aim of this article is to describe epidemiologic, radio anatomic and prognostic features of axillary nodal involvement breast cancer and to propose guidelines for 3D-conformal treatment planning in locally advanced breast cancers. This review is illustrated by a case report. (authors)

    We present a rare case of isolated axillary lymph node tuberculosis. A 66-year-old patient was admitted in order to perform the diagnostics of a painless tumor of the left armpit. Blood biochemistry tests and chest X-ray did not show any abnormalities. In the ultrasound examination a solid structure of the dimensions of 1.8×1 cm of irregular outline with adjacent hypoechogenic lymph nodes was visualized. The diagnosis of tuberculosis was based on histopathologic examination of the excised tumor. In the latter years an increase in extrapulmonary type of tuberculosis has been observed. Extrapulmonary tuberculosis may appear in practically each organ, nevertheless it affects pleura most often. Lymph node tuberculosis is the second, when it comes to the prevalence rate, type of extrapulmonary tuberculosis. In the majority of cases of lymph node tuberculosis it affects superficial lymph nodes. In the ultrasound examination a packet of pathological, enlarged and hypoechogenic lymph nodes is stated. In 1/3 of cases the central part of the nodes is hyperechogenic which indicates its caseation necrosis. Lymph nodes have a tendency to be matted and they have blurred outline. We observed this type of lymph node image in the presented patient. This image may be a diagnostic hint. Nevertheless, in the differentiation diagnostics one should take many other disease entities into consideration, inter alia: sarcoidosis, lymphomas, fungal infections, neoplastic metastases; the latter ones have an image most similar to tuberculosis lymph nodes. Tuberculosis ought to be considered in differential diagnosis of atypical masses.

The variables analyzed were the area reached by the lymphatic flow in the upper limb and the sites and number of lymph nodes identified in the ALND or SLNB groups visualized in the three phases of LS acquisition (immediate dynamic and static images, delayed scan images. For all analyses, the level of significance was set at 5%.Results: There was a significant difference between the ALND and SLNB groups, with predominant visualization of lymphatic flow and/or lymph nodes in the arm and axilla (P=0.01 and extra-axillary lymph nodes (P<0.01 in the ALND group. There was no significant difference in the total number of lymph nodes identified between the two groups. However, there was a significant difference in the distribution of lymph nodes in these groups. The cubital lymph node was more often visualized in the immediate dynamic images in the ALND group (P=0.004, while the axillary lymph nodes were more often identified in the delayed scan

    AIM: To investigate the significance of abnormal axillary lymph nodes detected at mammographic screening in the absence of a concomitant breast lesion. METHODS: Twenty-three thousand, seven hundred and seven women were screened at the Merrion Unit as part of the Irish National Breast Screening Programme ('BreastCheck') in the period June 2000 to July 2002. Nine women (0.4 per 1000 women screened) were found to have an abnormal axillary lymph node(s) in the absence of a mammographic breast lesion and were recalled for assessment. The radiological criteria for recall included: size greater than or equal to 15 mm, round or irregular shape, increased node density and absence of hilar lucency. Each woman underwent further mammographic views, ultrasound examination of axilla and breast, clinical examination and lymph node biopsy either by 14 G needle core biopsy (NCB) or open excision. RESULTS: The final pathological diagnoses in the nine patients were oestrogen receptor (OR) positive metastatic breast carcinoma (two patients), metastatic malignant melanoma (one patient), malignant lymphoma (two patients), caseating granulomatous lymphadenitis suggestive of tuberculosis (one patient), and other benign conditions (three patients). CONCLUSION: Abnormal axillary lymph nodes, in the absence of an accompanying breast lesion, are rarely identified on screening mammogram, but may harbour significant pathology and their presence on screening mammogram merits further investigation including biopsy.

    Purpose: To provide a strategy for precise co-localization of lymph nodes on axillary lymph-node dissection (ALND) specimens both on pathology and MR. To identify nodal features suggestive of metastatic involvement on a node-to-node basis. Materials and methods: National Institutional review-board approved this prospective study of 18 patients with breast cancer referred for ALND. Ex vivo T1 and inversion recovery (IR) T2 WI of ALND specimens tightly positioned within scaled plastic cranes was performed immediately after surgery. The correspondence of MR-based or pathologically based nodes location was assessed. The MR size and morphological presentation of metastatic and normal nodes were compared (Student's t-test or Mann-Whitney test). Quantitative variables were compared using Pearson coefficient. Results: 207 nodes were retrieved on pathology and 165 on MR. MR-pathological correlation of nodes location was high regarding MR-identified nodes (r = 0.755). An MR short axis threshold of 4 mm yielded the best predictive value for metastatic nodal involvement (Se = 78.6%; Sp = 62.3%). Irregular contours (Se = 35.7%; Sp = 96.7%), central nodal hyper-intensity on IR T2 WI (Se = 57.1%; Sp = 91.4%), and a cortical thickness above 3 mm (Se = 63.6%; Sp = 83.2%) were significantly associated with metastatic involvement. Conclusion: Ex vivo MR allows node-to-node correlation with pathology. Morphological MR criteria can suggest metastatic involvement

    Lymphedema is a relatively common, potentially serious and unpleased complication after axillary lymph node dissection (ALND) for breast cancer. It may be associated with functional, esthetic, and psychological problems, thereby affecting the quality-of-life (QOL) of breast cancer survivors. Objective measurements (preferentially by measuring arm volumes or arm circumferences at predetermined sites) are required to identify lymphedema, but also subjective assessment can help to determine the clinical significance of any volume/circumference differences. Lymphedema per se predisposes to the development of other secondary complications, such as infections of the upper limb, psychological sequelae, development of malignant tumors, alterations of the QOL, etc. The risk of lymphedema is associated with the extent of ALND and the addition of axillary radiation therapy. Treatment involves the application of therapeutic measures of the so-called decongestive lymphatic therapy. Prevention is of key importance to avoid lymphedema formation. The application of the sentinel lymph node biopsy in the management of breast cancer has been associated with a reduced incidence of lymphedema formation.

    While tuberculosis is still the leading opportunistic infection among human immunodeficiency virus-seropositive patients, extra-pulmonary tuberculosis is more common than pulmonary tuberculosis, with lymph nodes being a common site. Axillary lymph node pathology such as tuberculosis and lymphoma rarely mimics inflammatory breast carcinoma by producing lymphatic obstruction. We report a case of axillary lymph node tuberculosis in a 40-year-old immune-compromised woman, clinically presenting as inflammatory breast carcinoma. © The Author(s) 2015.

    Full Text Available Abstract Background For patients with early breast cancer and lymph node metastasis, axillary treatment is widely recommended. This is either surgical removal of the axillary lymph nodes, or axillary radiotherapy. The rationale for axillary treatment is that it will reduce the risk of recurrence in the axilla, and may improve survival. However, both treatments are associated with adverse effects, such as lymphedema, pain and sensory loss, and are costly to the health services and to patients. With improvements in adjuvant therapy, routine axillary treatment may no longer offer any overall advantage. Objectives To assess the short and long term benefits and adverse effects of routine axillary treatment (axillary lymph node clearance or axillary radiotherapy for patients with lymph node positive early-stage breast cancer. Methods/Design Criteria for potentially eligibility for the study will be that the participants are men and women with early breast cancer and lymph nodes with metastasis. The study compares either axillary treatment with no axillary treatment, or axillary node clearance with axillary radiotherapy, and the study is a randomized trial. Primary outcomes are axillary recurrence, disease-free and overall survival. Secondary outcomes include breast or chest wall recurrence, distant metastasis, time to axillary recurrence, axillary recurrence-free survival, arm morbidity, quality of life and health economic costs. The search strategy will include the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and WHO International Clinical Trials Registry Platform (ICTRP search portal. Two independent reviewers will assess studies for inclusion in the review, assess study quality and extract data. Characteristics of included studies will be described. Meta-analysis will be conducted using ReVman software. Comment This review addresses an important clinical question, and results will inform clinical practice and health care policy.

    The current management of the axilla in level 1 node-positive breast cancer patients is axillary lymph node dissection regardless of the status of the level 2 axillary lymph nodes. The goal of this study was to develop a nomogram predicting the probability of level 2 axillary lymph node metastasis (L-2-ALNM) in patients with level 1 axillary node-positive breast cancer. We reviewed the records of 974 patients with pathology-confirmed level 1 node-positive breast cancer between 2010 and 2014 at the Liaoning Cancer Hospital and Institute. The patients were randomized 1:1 and divided into a modeling group and a validation group. Clinical and pathological features of the patients were assessed with uni- and multivariate logistic regression. A nomogram based on independent predictors for the L-2-ALNM identified by multivariate logistic regression was constructed. Independent predictors of L-2-ALNM by the multivariate logistic regression analysis included tumor size, Ki-67 status, histological grade, and number of positive level 1 axillary lymph nodes. The areas under the receiver operating characteristic curve of the modeling set and the validation set were 0.828 and 0.816, respectively. The false-negative rates of the L-2-ALNM nomogram were 1.82% and 7.41% for the predicted probability cut-off points of level 1 axillary lymph node metastasis. Patients with a low probability of L-2-ALNM could be spared level 2 axillary lymph node dissection, thereby reducing postoperative morbidity.

    Full Text Available Objective: To describe mammographic characterization of breast cancer associated with axillary lymph node metastasis at King Chulalongkorn Memorial Hospital. Methods: The data were collected retrospectively from female patients with breast cancers who underwent breast surgery and axillary node dissection at King Chulalongkorn Memorial Hospital during January 1, 2004 and July 31, 2011. One hundred and ninety histopathologically proven cases of invasive ductal carcinoma (IDC were randomly recruited; consisted of ninety-five patients with axillary lymph node metastasis and the rest of patients without axillary lymph node metastasis. All patients were reviewed their mammograms with additional ultrasounds and correlation between each mammographic characteristic and ipsilateral node involvement was analyzed, using P-value (P, Odd ratio (OR and 95% confidence interval (CI. Results: Mammographic characterization associated with the highest risk of axillary node metastasis was malignant pattern of ipsilateral axillary node (P < 0.001; OR = 44.53; 95% CI = 13.10 - 151.37 with following by intermediate pattern of ipsilateral axillary node (P = 0.002; OR=5.18; 95% CI = 1.79 - 15.04. The other characteristics in descending orders for associated with axillary node involvement are upper outer quadrant tumors associated risk of ipsilateral axillary node involvement (P = 0.02; OR = 3.36; 95% CI = 1.23 - 9.14 and size of breast cancer by additional ultrasound (P = 0.04; OR = 1.48; 95% CI = 1.02-2.17. There was no association between risk of axillary node involvement and the rest of mammographic findings, including microcalcification of the tumor, vascularity of the tumor and size of axillary node. Conclusions: The highest predictive risk of axillary node metastasis in breast cancer was malignant axillary node pattern. The moderate risk was intermediate axillary node pattern and the lower risks were the tumor located in upper outer quadrant and increased tumor

    2013-01-01

    Full text: Introduction: Siliconoma, or silicone granuloma is the migration of silicon particles in the axillary lymph nodes, muscle and other non- ruptured or intact silicone implant. The latter is a relatively rare finding, and usually occurs in patients with extracapsular rupture of silicone prosthesis and has a typical ultrasound image. We present a case of a young woman with bilateral silicone prostheses placed 5 years ago, where in the right axilla are enlarged, structurally altered lymph nodes in the clinical and ultrasonography studies. Subsequent magnetic resonance examination shows intracapsular rupture ipsilateral silicone prosthesis and migration of silicon particles in the axillary lymph nodes. What you will learn: In this case we present twenty-three year old woman who reported pain and ‘swelling’ in the right axilla. The patient is with bilateral silicone prosthesis, she is not febrile and not reported other illness. After physical examination enlarged and tender lymph nodes in the right axilla was found. Several structurally altered and enlarged lymph nodes were visualized by ultrasound. These lymph nodes are hypoechogenic with obliterated fatty hilus. Due to the suspicion of silicone ‘extravasation’ in axillary lymph nodes, a magnetic resonance study of both mammary glands was performed. The images show intracapsular rupture of the right prosthesis without reliable data on silicone gel outside the fibrous capsule. Discussion: Siliconoma is a complication after plastic surgery of the breast and can affect both the axillary lymph nodes, and other lymphatic chains and also muscle and lung. Most frequently it occurs at damage of the extracapsular silicone prostheses. More rarely siliconoma occurs in siliconoma intracapsular damage, as in the presented case or in a silicone gel microbleed. Conclusion: The presence of siliconoma in axillary lymph nodes is relatively rare complication in plastic surgery of the breast. Methods of imaging diagnostic

    Coexistence of breast cancer and tuberculosis is rare. In most cases, involvement by tuberculosis occurs in axillary lymph nodes. We report a case of a 43-years-old patient who had undergone adenomastectomy and left sentinel lymph node biopsy due to a triple negative ductal carcinoma. At the end of adjuvant treatment, the patient had an atypical lymph node in the left axilla. Lymph node was excised, and after laboratory analysis, the diagnosis was ganglion tuberculosis. The patient underwent treatment for primary tuberculosis. The development of these two pathologies can lead to problems in diagnosis and treatment. An accurate diagnosis is important to avoid unnecessary surgical procedures.

    Full Text Available Background: Sentinel lymph node biopsy is a standard method for the evaluation of axillary status in patients with T1-2N0M0 breast cancers. Aims: To determine the prognostic significance of primary tumour-related clinico-histopathological factors on axillary and non-sentinel lymph node involvement of patients who underwent sentinel lymph node biopsy. Study design: Retrospective clinical study. Methods: In the present study, 157 sentinel lymph node biopsies were performed in 151 consecutive patients with early stage breast cancer between June 2008 and December 2011. Results: Successful lymphatic mapping was obtained in 157 of 158 procedures (99.4%. The incidence of larger tumour size (2.543±1.21 vs. 1.974±1.04, lymphatic vessel invasion (70.6% vs. 29.4%, blood vessel invasion (84.2% vs. 15.8%, and invasive lobular carcinoma subtype (72.7% vs. 27.3% were statistically significantly higher in patients with positive SLNs. Logistic stepwise regression analysis disclosed tumour size (odds ratio: 1.51, p=0.0021 and lymphatic vessel invasion (odds ratio: 4.68, p=0.001 as significant primary tumour-related prognostic determinants of SLN metastasis. Conclusion: A close relationship was identified between tumour size and lymphatic vessel invasion of the primary tumour and axillary lymph node involvement. However, the positive predictive value of these two independent variables is low and there is no compelling evidence to recommend their use in routine clinical practice.

    Paracoccidioidomycosis is an important medical and social problem mainly in rural areas of Brazil, because of the high incidence of the diseases, its long clinical evolution, frequent recurrences and sequels leading to anatomical and functional incapacities. We present a 73-year-old patient with paracoccidioidomycosis showing significant lymph node manifestations, which are only common in children and teenagers. Paracoccidioidomycosis may have a long incubation period, and it can be diagnosed outside of the endemic regions, where it was acquired. Thus, all dermatologists should maintain a high index of suspicion, especially in unusual cases of extensive lymph node enlargement in the elderly patients.

    Purpose: Sentinel lymph node-positive (SLN+) patients who are unlikely to have 4 or more involved axillary nodes might be treated with less extensive regional nodal radiation. The purpose of this study was to define possible predictors of having 4 or more involved axillary nodes. Methods and Materials: The records of 224 patients with breast cancer and 1 to 3 involved SLNs, who underwent completion axillary dissection without neoadjuvant chemotherapy or hormonal therapy were reviewed. Factors associated with the presence of 4 or more involved axillary nodes (SLNs plus non-SLNs) were evaluated by Pearson chi-square test of association and by simple and multiple logistic-regression analysis. Results: Of 224 patients, 42 had involvement of 4 or more axillary nodes. On univariate analysis, the presence of 4 or more involved axillary nodes was positively associated with increased tumor size, lobular histology, lymphovascular space invasion (LVSI), increased number of involved SLNs, decreased number of uninvolved SLNs, and increased size of SLN metastasis. On multivariate analysis, the presence of 4 or more involved axillary nodes was associated with LVSI, increased number of involved SLNs, increased size of SLN metastasis, and lobular histology. Conclusions: Patients with 1 or more involved SLN, LVSI, or SLN macrometastasis should be treated to the supraclavicular fossa/axillary apex if they do not undergo completion axillary dissection. Other SLN+ patients might be adequately treated with less extensive radiation fields

    Full Text Available Trough computed tomography (CT, it is possible to evaluate lymph nodes in detail and to detect changes in these structures earlier than with radiographs and ultrasound. Lack of information in the veterinary literature directed the focus of this report to normal aspects of the axillary and mediastinal lymph nodes of adult dogs on CT imaging. A CT scan of 15 normal adult male and female Rottweilers was done. To define them as clinically sound, anamnesis, physical examination, complete blood count, renal and hepatic biochemistry, ECG, and thoracic radiographs were performed. After the intravenous injection of hydrosoluble ionic iodine contrast medium contiguous 10mm in thickness thoracic transverse images were obtained with an axial scanner. In the obtained images mediastinal and axillary lymph nodes were sought and when found measured in their smallest diameter and their attenuation was compared to musculature. Mean and standard deviation of: age, weight, body length and the smallest diameter of the axillary and mediastinal lymph nodes were determined. Mean and standard deviation of parameters: age 3.87±2.03 years, weight 41.13±5.12, and body length 89.61±2.63cm. Axillary lymph nodes were seen in 60% of the animals, mean of the smallest diameter was 3.58mm with a standard deviation of 2.02 and a minimum value of 1mm and a maximum value of 7mm. From 13 observed lymph nodes 61.53% were hypopodense when compared with musculature, and 30.77% were isodense. Mediastinal lymph nodes were identified in 73.33% of the dogs; mean measure of the smallest diameter was 4.71mm with a standard deviation of 2.61mm and a minimum value of 1mm, and a maximum value of 8mm. From 14 observed lymph nodes 85.71% were isodense when compared with musculature and 14.28% were hypodense. The results show that it is possible to visualize axillary and mediastinal lymph nodes in adult clinically sound Rottweilers with CT using a slice thickness and interval of 10mm. The

    The presence of axillary lymph node metastases is the most important prognostic factor in breast cancer and can influence the selection of adjuvant therapy, both chemotherapy and radiotherapy. In this work we present a set of kinetic statistics derived from DCE-MRI for predicting axillary node status. Breast DCE-MRI images from 69 women with known nodal status were analyzed retrospectively under HIPAA and IRB approval. Axillary lymph nodes were positive in 12 patients while 57 patients had no axillary lymph node involvement. Kinetic curves for each pixel were computed and a pixel-wise map of time-to-peak (TTP) was obtained. Pixels were first partitioned according to the similarity of their kinetic behavior, based on TTP values. For every kinetic curve, the following pixel-wise features were computed: peak enhancement (PE), wash-in-slope (WIS), wash-out-slope (WOS). Partition-wise statistics for every feature map were calculated, resulting in a total of 21 kinetic statistic features. ANOVA analysis was done to select features that differ significantly between node positive and node negative women. Using the computed kinetic statistic features a leave-one-out SVM classifier was learned that performs with AUC=0.77 under the ROC curve, outperforming the conventional kinetic measures, including maximum peak enhancement (MPE) and signal enhancement ratio (SER), (AUCs of 0.61 and 0.57 respectively). These findings suggest that our DCE-MRI kinetic statistic features can be used to improve the prediction of axillary node status in breast cancer patients. Such features could ultimately be used as imaging biomarkers to guide personalized treatment choices for women diagnosed with breast cancer.

    Although sentinel lymph node biopsy(SLNB)is highly accurate in predicting axillary nodal status in patients with breast cancer, it has been shown that the procedure is associated with a few false negative results. The risk of leaving metastatic nodes behind in the axillary basin when SLNB is negative should be estimated for an individual patient if SLNB is performed to avoid conventional axillary lymph node dissection(ALND). A retrospective analysis of 512 women with T1-3N0M0 breast cancer was conducted to derive a prevalence of nodal metastasis by T category as a pre-test(i.e., before SLNB)probability and to examine potential confounders on the relationship between T category and axillary nodal involvement. Probability of nodal metastasis when SLNB was negative was estimated by means of Bayes' theorem which incorporated the pre-test probability and sensitivity and specificity of SLNB. Axillary nodal metastasis was observed in 6.1% of T1a-b, 25.1% of T1c, 28.7% of T2, 35.0% of T3 tumors. Point estimates for the probability of nodal involvement when SLNB was negative ranged from 0.3-1.3% for T1a-b, 1.6-6.3% for T1c, 2.0-7.5% for T2, and 2.6-9.7% for T3 tumors with representative sensitivities of 80%, 85%, 90% and 95%, respectively. The risk may be higher when the tumor involves the upper outer quadrant of the breast, while it may be lower for an underweight woman. The probability of axillary lymph node metastasis when SLNB is negative can be estimated using a Bayesian approach. Presenting the probability to the patient may guide the decision of surgery without conventional ALND.

    A retrospective study was performed to evaluate whether dynamic MR imaging is useful for the diagnosis of axillary lymph node metastases from breast cancer. Thirty-five patients with breast cancer were scanned and 147 lymph nodes were detected and compared with pathological nodal status. The parameters were the long axis dimension, the short axis dimension, the long-to-short axis (L/S) ratio, the shape, the contrast enhancement ratio (CER), the CER of lymph node-to-primary tumor (L/P) ratio. All parameters had significant differences between metastatic and normal nodes and there was a positive correlation between the CER of primary breast tumors and metastatic nodes. Multivariate analysis identified three parameters: the shape, the CER (1st phase), the L/P ratio (1st phase). ROC analysis revealed the shape and CER are superior in diagnostic performance to L/P ratio. If the shape and CER (1st phase) 60% and above are employed as criteria, the sensitivity, the specificity, the accuracy and the positive and negative predictive value were 86.0%, 78.4%, 81.0%, 67.2% and 91.6%, respectively. This method gives us useful information about the evaluation of axillary lymph node status preoperatively. (author)

  11. Observation of the Primo Vessel Approaching the Axillary Lymph Node with the Fluorescent Dye, DiI

    Full Text Available The primo vascular system (PVS floating in lymph fluid has mostly been observed in large caliber ducts around the caudal vena cava and the thoracic duct of rabbits, rats, and mice. But the PVS has not been traced up to the lymph nodes. It has not been established whether the PVS leaves the lymph vessel through the lymph vessel wall or it enters the lymph nodes. Therefore, observing the PVS entering a lymph node, for example, the axillary node, is desirable. In the current work, we traced the PVS approaching up to the surface of axillary node of a rat. The method used for this study was based upon a method that was recently developed to detect the PVS in the lymph duct from the inguinal to the axillary nodes in the skin of a rat by injecting Alcian blue into the inguinal node. However, the Alcian blue blurred near the lymph nodes and tracing the PVS up to the lymph nodes has not been possible. The current method clearly showed the PVS approaching the axillary node.

    Full Text Available The primo vascular system (PVS in a lymph system was observed mostly in large caliber ducts around the caudal vena cava of rabbits, rats, and mice. This required a severe surgery with laparectomy and massive removal of fat tissues in the abdomen to expose the lymph vessel. In the current brief report, we presented a new method to evade these shortcomings by observing the PVS in a less large caliber duct in the skin, that is, the lymph vessel from the inguinal to the axillary nodes. The Alcian blue injection into the inguinal node revealed the desired primo vessel in the target lymph vessel. This opened a new perspective for the investigation of the lymphatic PVS without severe damage to subject animals and for monitoring of the PVS in a long period of time.

    Axillary lymph node metastasis without breast involvement from ovarian cancer is rare. We report a case of a 68-year-old woman proven as ovarian serous papillary carcinoma and metastatic papillary carcinoma of the omentum on surgical diagnostic laparoscopy. In addition, a hypermetabolic lymph node was detected in left axilla and was considered a reactive benign lesion. Mammography and ultrasonography showed no focal lesion in both breasts, but ultrasonography-guided core needle biopsy for the lymph node revealed metastatic serous papillary carcinoma from ovarian origin. Even with a low incidence of axillary lymph node metastasis without breast involvement from ovarian cancer and only marginally elevated standardized uptake value in positron emission tomography, the possibility of metastasis at axillary lymph node in patients with known primary ovarian cancer must be considered.

    Full Text Available Breast cancer is a major cause of mortality in women due to malignant diseases and is the most prevalent type of cancer in western countries. According to investigations which has been done in Iran so far, the prevalence of disease in our country is also very high, therefore complete attention to clinical and pathological findings of this disease would be extremely essential. In this study, the direct relationship between axillary lymph node involvement and the aggressiveness of invasive ductal carcinoma has been brought into consideration. This study is a case series of 90 patients which all of them have had radical mastectomy because of breast cancer and all their samples has been referred to the center of pathology of Imam hospital. Based on modified Bloom-Richardson grading, all the samples have been graded. The study of all lymph node samples related to above cases has also been conducted along with the main study. The most frequent ages of disease was 31 to 40 and left breast had most involvement. From all cases, 12.2% were in grade I with 27.2% lymph node involvement, 66.7% grade II with 73.4% lymph node involvement and 21.1% in grade III with 100% lymph node involvement (P=0.00008. Based on statistical analysis we concluded that the axillary lymph node involvement in breast cancer is strongly associated with the aggressiveness of invasive ductal carcinoma. This important point should not be neglected in planning for treatment of this kind of disease.

    Full Text Available Triple negative breast cancer (TNBC is breast cancer that demonstrate the absence of estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2. TNBC has an aggressive behaviour, high frequency of metastasis to the axillary lymph nodes and recurrence, and poor prognosis. Metastasis to the axillary lymph nodes will affect the rate of survival and recurrence in TNBC. Melanoma cell adhession molecule (MCAM is a membrane glycoprotein of the immunoglobulin superfamily, which is involved in the cells binding, which later became known as the marker for the progression and metastasis of melanoma and carcinoma of the prostate. However, MCAM role in mammary carcinoma still controversial. The aim of this study was to assess correlation between MCAM expression with incidence of metastatic to axillary lymph nodes in TNBC. This research was conducted during January 1st 2010–April 31st 2015 at Pathology Anatomy, Faculty of Medicine, Universitas Padjadjaran. This study used a cross-sectional design, using lambda correlation test. MCAM immunohistochemical staining performed on 56 samples of paraffin blocks of TNBC group that did not metastasized and has metastasized to the axillary lymph nodes. A total of 22 of 28 (78.6% of TNBC metastatic to axillary lymph nodes have histoskor MCAM value <4 (negative, whereas 16 of 28 (57.1% of TNBC non-metastatic have histoskor value ≥ 4 (positive. Negative expression of MCAM correlated with TNBC that had metastasized to axillary lymph nodes, although not the only factor that influenced them.

    Background: To assess the long term complications of level II Axillary Lymph Node Dissection (AXLND) in patients with breast cancer and to see if they are high enough to warrant a Sentinel Lymph Node (SLN) biopsy in all patients presenting with carcinoma breast in our setup in Pakistan. Methods: This study was conducted at Surgical Unit IV, Department of Surgery, Combined Military Hospital, Rawalpindi. Upper, lower arm circumferences and body mass index were ascertained in post Modified Radical Mastectomy (MRM) with level II AXLND, in female patients who had undergone surgeries from 1992 to 2008. Patient's perception of degree of lymph oedema, arm function and other symptoms like pain, tingling and numbness was noted. The number of lymph nodes removed, number of positive nodes and post operative radiotherapy were also recorded from the hospital records. Results: Thus upper arm circumference in 85.7% patients and lower arm circumference in 89.2% patients was within 2 Cm of the unaffected side. No, moderate and severe arm swelling was described by 83.35% of patients, 11.6% of patients and one patient respectively and 41.5% of patients describing some arm swelling had positive lymph nodes. Thus even if they had gone (SLN) biopsy, these patients would have had a subsequent AXLND. Over 94% of patients had either good or excellent arm function with most in the excellent range. Conclusion: The patients at significant risk for positive nodal may be better served with an AXLND rather than the SLN technique. (author)

    Purpose: We sought to determine the rate of postmastectomy radiation therapy (PMRT) among women treated with axillary lymph node dissection (ALND) after positive sentinel lymph node (SLN) biopsy results and to establish the effect of negative ALND results and PMRT on locoregional recurrence (LRR) and overall survival (OS). Methods and Materials: All patients were treated with mastectomy and ALND after positive SLN biopsy results. All patients had clinical N0 or NX disease at the time of mastectomy and received no neoadjuvant therapy. The presence of lymphovascular space invasion, presence of multifocality, number of positive SLNs and non-SLNs, clinical and pathologic stage, extranodal extension, age, and use of PMRT were evaluated for significance regarding the rates of OS and LRR. Results: A total of 345 patients were analyzed. ALND after positive SLN biopsy results was negative in 235 patients (68.1%), and a total of 112 patients (32.5%) received radiation therapy. On multivariate analysis, only pathologic stage III predicted for lower OS (hazard ratio, 3.32; P<.001). The rate of 10-year freedom from LRR was 87.9% and 95.3% in patients with positive ALND results and patients with negative ALND results, respectively. In patients with negative ALND results with ≥3 positive SLNs, the rate of freedom from LRR was 74.7% compared with 96.7% in those with <3 positive SLNs (P=.009). In patients with negative ALND results, ≥3 positive SLNs predicted for an increase in LRR on multivariate analysis (hazard ratio, 10.10; P=.034). Conclusions: A low proportion of cT1-2, N0 patients with positive SLNs who undergo mastectomy receive PMRT after ALND. Even in this low-risk cohort, patients with ≥3 positive SLNs and negative ALND results are at increased risk of LRR and may benefit from PMRT.

    Full Text Available Abstract Background The standard treatment of the axilla in breast cancer used to be an axillary lymph node dissection. An axillary lymph node dissection is known to give substantial risks of morbidity. In recent years the sentinel node biopsy has become common practice. Future randomized study results will determine whether the expected decrease in morbidity can be proven. Methods Before the introduction of the sentinel node biopsy, we conducted a study in which 180 women of 50 years and older with T1/T2 cN0 breast cancer were treated with breast conserving therapy. Instead of an axillary lymph node dissection regional radiotherapy was given in combination with tamoxifen (RT-group. The study group was compared with 341 patients, with the same patient and tumour characteristics, treated with an axillary lymph node dissection (S-group. Results The treatment groups were comparable, except for age. The RT-group was significantly older than the S-group. The median follow up was 7.2 years. The regional relapse rates were low and equal in both treatment groups, 1.1% in RT-group versus 1.5% in S-group at 5 years. The overall survival was similar; the disease free survival was significant better in the RT-group. Conclusion Regional recurrence rates after regional radiotherapy are very low and equal to an axillary lymphnode dissection.

    Adenoid cystic carcinoma (ACC) of the breast is a rare malignant salivary-type neoplasm that has a good prognosis and represents less than 1% of all breast cancers. It is a triple negative carcinoma that presents as a painful mass. The mean age at the time of diagnosis is 50-60 years old. The solid variant of this type of tumour with basaloid features and presence of nodal metastases is very rare and considered to have a more aggressive clinical course. We present a case with presence of axillary lymph node metastases that was successfully treated with no evidence of recurrence one year after the diagnosis and review the literature.

    A tattoo is defined as the intentional or accidental deposit of pigment into the skin. The phenomenon of skin tattooing is on the rise worldwide and complications of tattooing are increasingly being recognised in diagnostic and clinical medicine. We describe a case of calcification-like changes on mammography resembling that of breast malignancy as a result of tattoo pigment deposition in an axillary lymph node. Recognition of such changes in routine breast screening is crucial to avoid further unnecessary invasive investigations and surgery in such patients. PMID:23929611

    Safety of sentinel lymph node (SLN) biopsy for breast cancer during pregnancy is insufficiently explored. We investigated efficacy and local recurrence rate in a large series of pregnant patients. Women diagnosed with breast cancer who underwent SLN biopsy during pregnancy were identified from the International Network on Cancer, Infertility and Pregnancy, the German Breast Group, and the Cancer and Pregnancy Registry. Chart review was performed to record technique and outcome of SLN biopsy, locoregional and distant recurrence, and survival. We identified 145 women with clinically N0 disease who underwent SLN during pregnancy. The SLN detection techniques were as follows: 99m Tc-labeled albumin nanocolloid only (n = 96; 66.2%), blue dye only (n = 14; 9.7%), combined technique (n = 15; 10.3%), or unknown (n = 20; 13.8%). Mapping was unsuccessful in one patient (0.7%) and she underwent an axillary lymph node dissection (ALND). Mean number of SLNs was 3.2 (interquartile range 1-3; missing n = 15). Positive SLNs were found in 43 (29.7%) patients and 34 subsequently underwent ALND. After a median follow-up of 48 months (range 1-177), 123 (84.8%) patients were alive and free of disease. Eleven patients experienced a locoregional relapse, including 1 isolated ipsilateral axillary recurrence (0.7%). Eleven (7.6%) patients developed distant metastases, of whom 9 (6.2%) died of breast cancer. No neonatal adverse events related to SLN procedure during pregnancy were reported. SLN biopsy during pregnancy has a comparably low axillary recurrence rate as in nonpregnant women. Therefore, this method can be considered during pregnancy instead of standard ALND for early-stage, clinically node-negative breast cancer.

  4. The role of ultrasound and lymphoscintigraphy in the assessment of axillary lymph nodes in patients with breast cancer

    Full Text Available Breast cancer is the most common malignancy and the leading cause of death due to cancer in European women. Mammography screening programs aimed to increase the detection of early cancer stages were implemented in numerous European countries. Recent data show a decrease in mortality due to breast cancer in many countries, particularly among young women. At the same time, the number of sentinel node biopsy procedures and breast-conserving surgeries has increased. Intraoperative sentinel lymph node biopsy preceded by lymphoscintigraphy is used in breast cancer patients with no clinical signs of lymph node metastasis. Due to the limited sensitivity and specificity of physical examination in detecting metastatic lesions, developing an appropriate diagnostic algorithm for the preoperative assessment of axillary lymph nodes seems to be a challenge. The importance of ultrasound in patient qualification for sentinel lymph-node biopsy has been discussed in a number of works. Furthermore, different lymphoscintigraphy protocols have been compared in the literature. The usefulness of novel radiopharmaceuticals as well as the methods of image acquisition in sentinel lymph node diagnostics have also been assessed. The aim of this article is to present, basing on current guidelines, literature data as well as our own experience, the diagnostic possibilities of axillary lymph node ultrasound in patient qualification for an appropriate treatment as well as the role of lymphoscintigraphy in sentinel lymph node biopsy.

    Regional radiotherapy (RT) is increasingly used in breast cancer treatment. Conventionally, computed tomography (CT) is performed for RT planning. Lymph node (LN) target levels are delineated according to anatomical boundaries. Magnetic resonance imaging (MRI) could enable individual LN delineation. The purpose was to evaluate the applicability of MRI for LN detection in supine treatment position, before and after sentinel-node biopsy (SNB). Twenty-three female breast cancer patients (cTis-3N0M0) underwent 1.5 T MRI, before and after SNB, in addition to CT. Endurance for MRI was monitored. Axillary levels were delineated. LNs were identified and delineated on MRI from before and after SNB, and on CT, and compared by Wilcoxon signed-rank tests. LN locations and LN-based volumes were related to axillary delineations and associated volumes. Although postoperative effects were visible, LN numbers on postoperative MRI (median 26 LNs) were highly reproducible compared to preoperative MRI when adding excised sentinel nodes, and higher than on CT (median 11, p  <  0.001). LN-based volumes were considerably smaller than respective axillary levels. Supine MRI of LNs is feasible and reproducible before and after SNB. This may lead to more accurate RT target definition compared to CT, with potentially lower toxicity. With the MRI techniques described here, initiation of novel MRI-guided RT strategies aiming at individual LNs could be possible.

    The objectives of this study were to electromyographically (EMG) describe and analyze factors associated with long thoracic nerve injuries in breast cancer patients after axillary lymph node dissection. This was a prospective longitudinal observational study. Two hundred sixty-four women with primary invasive breast cancer were included between 2008 and 2011. All of them were treated by axillary lymph node dissection. Patients were evaluated at 1, 6, and 12 months following surgery. The presence of winged scapula was systematically tested at each follow-up and an EMG performed whenever it was observed. Affected and unaffected groups were compared for demographic, tumour, and treatment variables. Student t test, Mann-Whitney U test, chi-squared or Fisher test were computed as appropriate. Among the 36 (13.6%) winged scapula observed, the EMG confirmed long thoracic nerve injury in 30 (11.3%) of them, 27 were partial axonotmesis and three were severe axonotmesis. At 12 months, the EMG showed that injury persisted in six (2.27%) patients. Patients with long thoracic nerve injury had a lower body mass index than unaffected patients (26.2 vs. 28.2, p = 0.045). Age, tumour stage, type of breast surgery, nodes excised, surgical complications, previous chemotherapy and previous hormonotherapy were not factors associated with winged scapula.

    Full Text Available Abstract Background Breast cancer is the first cause of cancer death among women and its incidence doubled in the last two decades. Several approaches for the treatment of these cancers have been developed. The axillary lymph node dissection (ALND leads to numerous morbidity complications and is now advantageously replaced by the dissection and the biopsy of the sentinel lymph node. Although this approach has strong advantages, it has its own limitations which are manipulation of radioactive products and possible anaphylactic reactions to the dye. As recently proposed, these limitations could in principle be by-passed if semiconductor nanoparticles (quantum dots or QDs were used as fluorescent contrast agents for the in vivo imaging of SLN. QDs are fluorescent nanoparticles with unique optical properties like strong resistance to photobleaching, size dependent emission wavelength, large molar extinction coefficient, and good quantum yield. Methods CdSe/ZnS core/shell QDs emitting around 655 nm were used in our studies. 20 μL of 1 μM (20 pmol QDs solution were injected subcutaneously in the anterior paw of healthy nude mice and the axillary lymph node (ALN was identified visually after injection of a blue dye. In vivo fluorescence spectroscopy was performed on ALN before the mice were sacrificed at 5, 15, 30, 60 min and 24 h after QDs injection. ALN and all other organs were removed, cryosectioned and observed in fluorescence microscopy. The organs were then chemically made soluble to extract QDs. Plasmatic, urinary and fecal fluorescence levels were measured. Results QDs were detected in ALN as soon as 5 min and up to 24 h after the injection. The maximum amount of QDs in the ALN was detected 60 min after the injection and corresponds to 2.42% of the injected dose. Most of the injected QDs remained at the injection site. No QDs were detected in other tissues, plasma, urine and feces. Conclusion Effective and rapid (few minutes detection of

    Axillary hair is a highly conserved phenotypical feature in humans, and as such deserves at least consideration of its functional significance. Protection from environmental factors is one of the main functions attributed to hair in furred vertebrates, but is believed to be inapplicable to humans. I considered the hypothesis that the phenotypic preservation of axillary hair is due to its unrecognized role in the organism protection. Two immediate questions arise--what exactly is being protected and what it is protected from. A large group of axillary lymph nodes represents a major difference between underarms and the adjacent areas of the trunk. The consideration of potential factors from which hair can offer protection identifies sunlight as the most likely candidate. Intense sweat production underarms may represent an independent defense mechanism, specifically protecting lymph nodes from overheating. Moreover, the pattern of facial hair growth in males strikingly overlaps with the distribution of superficial lymph nodes, suggesting potential role for facial hair in protection of lymph nodes, and possibly thymus and thyroid. The idea of lymph node protection from environmental mutagenic factors, such as UV radiation and heat, appears particularly important in light of wide association of lymph nodes with cancers. The position of contemporary fashion towards body hair is aggressively negative, including the social pressure for removal of axillary and bikini line hair for women, facial hair for men in many professional occupations, and even body hair for men. If this hypothesis is proven to be true, the implications will be significant for immunology (by providing new insights in lymph node physiology), health sciences (depilation is painful and therefore easily modifiable habit if proven to increase disease risk), as well as art, social fashion and economy.

    Purpose: To aim of this study was to evaluate the diagnostic accuracy of axillary lymph node sonography, if necessary in collaboration with US-guided large core biopsy, in the preoperative evaluation of breast cancer patients scheduled for quadrantectomy and sentinel lymph node excision. Materials and methods: From July 2001 to December 2002, we evaluated 117 breast cancer patients with ultrasound and, where indicated, FNAB. Breast lesions has diameters between 4 and 26 mm (mean diameter 11 mm). Fifteen (13%) of the 117 patients were excluded from the series as they did not found fulfil the criteria for preliminary sonography of the axilla: in 9 patients fewer than 4 nodes were detected and in 6 patients the breast lesions were intraoperatively found to be benign. Eleven patients (10.7%) with sonographically suspicious axillary nodes were sampled by US-guided core biopsy using a 14 or 16 Gauge Tru-Cut needle. Results: The ultrasound study aims to evaluate the dimensions and morphology of the breast lesion as well as detect and assess at least 4 axillary nodes. These were evaluated for hilar and cortical thickening and radio between the sinus diameter and the total longitudinal diameter. Lymph nodes with hilar diameters equal to or greater than 50% of the longitudinal diameter were considered normal. Of the 102 patients evaluated, 77 (75.7%) had normal axillary nodes according to the US criteria adopted. Negativity was confirmed by histology in 56 cases (72.7%, true negative); 21 (27.3%, false negative) were found to be positive, in contrast with the sonographic appearance. The false negative cases were due to lymph node micrometastasis which probably did not cause morphologic alterations perceptible at ultrasound. The remaining 25 patients (24.5%) had axillary lymph nodes classified as suspicious. In 13 cases of (52%, true positive) there was agreement with histology, whereas in 12 cases (48%, false positive) the US suspicion was not confirmed at surgery. The most

    Molecular heterogeneity within primary breast carcinomas and among axillary lymph node (LN) metastases may impact diagnosis and confound treatment. In this study, we used short tandem repeated sequences to assess genomic heterogeneity and to determine hereditary relationships among primary tumor areas and regional metastases from 30 breast cancer patients. We found that primary carcinomas were genetically heterogeneous and sampling multiple areas was necessary to adequately assess genomic variability. LN metastases appeared to originate at different time periods during disease progression from different sites of the primary tumor and the extent of genomic divergence among regional metastases was associated with a less favorable patient outcome (P = 0.009). In conclusion, metastasis is a complex process influenced by primary tumor heterogeneity and variability in the timing of dissemination. Genomic variation in primary breast tumors and regional metastases may negatively impact clinical diagnostics and contribute to therapeutic resistance. PMID:26279627

    We report the use of optical coherence tomography (OCT) to determine spatially localized optical attenuation coefficients of human axillary lymph nodes and their use to generate parametric images of lymphoid tissue. 3D-OCT images were obtained from excised lymph nodes and optical attenuation coefficients were extracted assuming a single scattering model of OCT. We present the measured attenuation coefficients for several tissue regions in benign and reactive lymph nodes, as identified by histopathology. We show parametric images of the measured attenuation coefficients as well as segmented images of tissue type based on thresholding of the attenuation coefficient values. Comparison to histology demonstrates the enhancement of contrast in parametric images relative to OCT images. This enhancement is a step towards the use of OCT for in situ assessment of lymph nodes.

    Concomitant breast cancer metastasis and tubercular lymphadenitis in axillary lymph node is an extremely rare occurrence. Axillary lymph node metastasis is the most important factor in the staging of breast carcinoma and the number of axillary nodes showing metastases alters the stage. As tuberculosis also produces nodal enlargement, this can mimic or complicate the staging of malignant disease. Dual pathology in an organ can lead to difficulties in interpretation and inappropriate treatment of tuberculosis as well as carcinoma breast. Moreover, fine needle aspiration cytology (FNAC) from such cases may be misleading if only one of the diseases is picked up. Therefore, the need for multiple attempts at FNAC should be stressed upon for all palpable lumps. We report a case of infiltrating duct carcinoma breast in a 45-year-old female where tuberculosis was discovered in axillary lymph nodes in addition to metastases. As the present case led to incidental discovery of tuberculosis with tumor metastasis, it reinforces the possibility of a coexistent lesion in the pathologists' mind, especially in regions endemic for tuberculosis.

    Purpose: To analyze the incidence and risk factors for locoregional recurrence (LRR) in patients with breast cancer who had T1 or T2 primary tumor and 1-3 histologically involved axillary lymph nodes treated with modified radical mastectomy without adjuvant radiotherapy (RT). Methods and Materials: Between April 1991 and December 1998, 125 patients with invasive breast cancer were treated with modified radical mastectomy and were found to have 1-3 positive axillary nodes. The median number of nodes examined was 17 (range 7-33). Of the 125 patients, 110, who had no adjuvant RT and had a minimum follow-up of 25 months, were included in this study. Sixty-nine patients received adjuvant chemotherapy and 84 received adjuvant hormonal therapy with tamoxifen. Patient-related characteristics (age, menopausal status, medial/lateral quadrant of tumor location, T stage, tumor size, estrogen/progesterone receptor protein status, nuclear grade, extracapsular extension, lymphovascular invasion, and number of involved axillary nodes) and treatment-related factors (chemotherapy and hormonal therapy) were analyzed for their impact on LRR. The median follow-up was 54 months. Results: Of 110 patients without RT, 17 had LRR during follow-up. The 4-year LRR rate was 16.1% (95% confidence interval [CI] 9.1-23.1%). All but one LRR were isolated LRR without preceding or simultaneous distant metastasis. According to univariate analysis, age <40 years (p=0.006), T2 classification (p=0.04), tumor size ≥3 cm (p=0.002), negative estrogen receptor protein status (p=0.02), presence of lymphovascular invasion (p=0.02), and no tamoxifen therapy (p=0.0006) were associated with a significantly higher rate of LRR. Tumor size (p=0.006) was the only risk factor for LRR with statistical significance in the multivariate analysis. On the basis of the 4 patient-related factors (age <40 years, tumor ≥3 cm, negative estrogen receptor protein, and lymphovascular invasion), the high-risk group (with 3 or 4

    The aim of our study was to evaluate sentinel lymph node biopsy as a diagnostic test for assessing the presence of residual metastatic axillary lymph nodes after neoadjuvant chemotherapy, replacing the need for a lymphadenectomy in negative selective lymph node biopsy patients. A multicentre, diagnostic validation study was conducted in the province of Tarragona, on women with T1-T3, N1-N2 breast cancer, who presented with a complete axillary response after neoadjuvant chemotherapy. Study procedures consisted of performing an selective lymph node biopsy followed by lymphadenectomy. A total of 53 women were included in the study. Surgical detection rate was 90.5% (no sentinel node found in 5 patients). Histopathological analysis of the lymphadenectomy showed complete disease regression of axillary nodes in 35.4% (17/48) of the patients, and residual axillary node involvement in 64.6% (31/48) of them. In lymphadenectomy positive patients, 28 had a positive selective lymph node biopsy (true positive), while 3 had a negative selective lymph node biopsy (false negative). Of the 28 true selective lymph node biopsy positives, the sentinel node was the only positive node in 10 cases. All lymphadenectomy negative cases were selective lymph node biopsy negative. These data yield a sensitivity of 93.5%, a false negative rate of 9.7%, and a global test efficiency of 93.7%. Selective lymph node biopsy after chemotherapy in patients with a complete axillary response provides valid and reliable information regarding axillary status after neoadjuvant treatment, and might prevent lymphadenectomy in cases with negative selective lymph node biopsy.

    Objective: Malignant axillary lymph nodes are an important predictor for breast cancer recurrence, but invasive dissection or biopsy is required for the diagnosis. We determined whether and how malignant nodes could be diagnosed preoperatively with magnetic resonance (MR) imaging. Materials and methods: We obtained MR images of all women evaluated for breast cancer at the Sun Yat-Sen University Cancer Center in 2010 and correlated the image characteristics of each axillary node with the pathologic diagnosis of the same node. Results: We analyzed 251 nodes (117 benign; 134 malignant) from 136 women (mean age, 44 years; range, 20–67). Mean diameter of the nodes was 18 mm (range, 5–58 mm). With pathologic diagnosis as the reference standard, MRI-based interpretations were 66.4% sensitive, 94% specific, and 79% accurate. Diameter, pathologic type, apparent diffusion coefficient value (ADC, b = 500 and 800), time-intensity curve (TIC) type of breast tumors correlated with node metastasis; ADC value (b = 500 and 800), TIC type, early enhancement rate, long-axis, short-axis, shape, margin and the location of nodes correlated with node metastasis (P < 0.001 for all). Tumor immunohistochemistry results for estrogen receptors, progesterone receptors, c-erbB-2, vascular endothelial growth factor, and Ki67 were not. An MRI-based lymph node scoring system based on these correlations had a specificity of 91%, a sensitivity of 93%, and an area under the ROC curve of 0.95 (P < 0.001). Conclusion: Metastatic axillary lymph nodes can be accurately diagnosed by MR in women with early breast cancer preoperatively and non-invasively. The scoring system appears to be superior to current methods.

    This study aimed to provide additional anatomical information for axillary lymph node dissection (ALND) through in vivo anatomy studies of intercostobrachial nerve (ICBN) preservation in order to provide theoretical and practical experience for clinicians. A total of 156 patients with breast cancer underwent ALND at the Department of Gynecology of Baotou Tumor Hospital between June 2009 and March 2010. The origin, destination, main source, length, branch type, and direction of ICBN in axilla were observed, as well as its relationship with adjacent major blood vessels and nerves within the axilla. There were 120 cases of single trunk, 23 cases of double trunks, 9 cases of multiple trunks, and 4 cases without trunks in 156 patients with ICBN preservation. The transverse diameter at the origin of the ICBN was 1.89 ± 0.44 mm with a length of 94.45 ± 12.08 mm; the distances were 77.19 ± 21.04 mm, 29.34 ± 6.73 mm, 90.04 ± 13.13 mm, and 28.63 ± 13.01 mm from origin to the inferior margin at the midpoint of the clavicle, inferior margin of the axillary vein, the bottom of axilla, and branch point, respectively. The identification, dissection, and preservation of ICBN was simple and easy in a modified radical mastectomy for breast cancer and breast-conserving surgery, which only took 10-20 min, but effectively reduced the incidence of post-mastectomy pain syndrome and significantly improved the quality of life for patients after surgery.

    Highlights: •Quantitative image analysis showed promise in evaluating axillary lymph nodes. •13 of 28 features performed better than guessing at metastatic status. •When all features were used in together, a considerably higher AUC was obtained. -- Abstract: Purpose: To assess the performance of computer extracted feature analysis of dynamic contrast enhanced (DCE) magnetic resonance images (MRI) of axillary lymph nodes. To determine which quantitative features best predict nodal metastasis. Methods: This institutional board-approved HIPAA compliant study, in which informed patient consent was waived, collected enhanced T1 images of the axilla from patients with breast cancer. Lesion segmentation and feature analysis were performed on 192 nodes using a laboratory-developed quantitative image analysis (QIA) workstation. The importance of 28 features were assessed. Classification used the features as input to a neural net classifier in a leave-one-case-out cross-validation and evaluated with receiver operating characteristic (ROC) analysis. Results: The area under the ROC curve (AUC) values for features in the task of distinguishing between positive and negative nodes ranged from just over 0.50 to 0.70. Five features yielded AUCs greater than 0.65: two morphological and three textural features. In cross-validation, the neural net classifier obtained an AUC of 0.88 (SE 0.03) for the task of distinguishing between positive and negative nodes. Conclusion: QIA of DCE MRI demonstrated promising performance in discriminating between positive and negative axillary nodes.

    Full Text Available INTRODUCTION: Ki-67 expression is a biomarker for proliferation. Its prognostic value is recognized in breast cancer (BC patients with negative axillary nodes, but is less clear in BC patients with positive axillary lymph nodes. METHODS: We retrospectively reviewed the medical records of 1131 Chinese BC patients treated from January 2002 to June 2007 and 450 patients met the inclusion criteria: positive nodes, adjuvant therapy, and complete biomarker profile (estrogen receptor (ER, progesterone receptor (PR, HER2, p53, Ki-67. Univariate and multivariate regression analysis were used to correlate biomarkers and tumor characteristics with metastasis free survival (MFS and overall survival (OS. RESULTS: Median follow-up time was 46 months (range 5-76 months. The Ki-67 expression was associated significantly with histological grade, ER, PR, HER2, and P53 status (P<0.05. Tumor stage, nodal stage, and ER status were independent prognostic factors for MFS. Ki-67 status was associated significantly with OS but not MFS. To determine whether the extent of LN involvement in the BC patients influenced the role of Ki-67 in survival rates, we compared these variables in patients with 1-3 positive lymph nodes (N1 to those of patients with ≥ 4 positive lymph nodes. Ki-67 status was an independent prognostic factor for MFS (Hazard Ratio, 3.27, P = 0.026 and overall survival (HR, 10.64, P = 0.007 in patients with 1-3 positive nodes (N1. CONCLUSIONS: The possibility that Ki-67 expression together with clinical factors can improve prediction of the prognosis of BC patients with 1 ∼ 3 positive axillary lymph nodes warrants further studies.

    The Hungarian National Institute of Oncology has just closed a single-center randomized clinical study. The Optimal Treatment of the Axilla-Surgery or Radiotherapy (OTOASOR) trial compares completion axillary lymph node dissection (cALND) with regional nodal irradiation (RNI) in patients with sentinel lymph node-positive (SLN+) primary invasive breast cancer. In the investigational treatment arm, patients received 50 Gy RNI instead of cALND. In these patients we had information only about the sentinel lymph node (SLN) status, but the further axillary nodal involvement remained unknown. The aim of this study was to investigate whether the result of cALND influenced the recommendation for adjuvant treatment in patients with SLN+ breast cancer. Patients with SLN+ primary breast cancer were randomized for cALND (arm A, standard treatment) or RNI (arm B, investigational treatment). Adjuvant systemic treatments were given according to the standard institutional protocol, and patients were followed according to the actual institutional guidelines. Between August 2002 and June 2009, 474 SLN+ patients were randomized to cALND (arm A, standard treatment = 244 patients) or RNI (arm B, investigational treatment = 230 patients). The 2 arms were well balanced according to the majority of main prognostic factors. However, more patients were premenopausal (34% vs. 27%; P = .095) and had pT2-3 tumors (57% vs. 40%; P = .003) in the completion axillary lymph node dissection (ALND) arm. On the other hand, there were more patients with known human epidermal growth factor receptor type 2 positive tumor (12% vs. 17%, P = .066) in the RNI arm. In the ALND and RNI arms, 78% (190/244) and 69% (159/230), respectively, received chemotherapy (P = .020). Endocrine therapy was administered in 87% (213/244) of the patients in the ALND arm and 89% (204/230) of the patients in the RNI arm (P = .372). Six patients (2.5%) on arm A and 13 patients (5.7%) on arm B received adjuvant trastuzumab

    ACOSOG Z11 and other studies showing little benefit to axillary dissection (ALND) for early-stage breast cancers with limited nodal disease have led to questioning the value of preoperative axillary imaging ± ultrasound-guided needle biopsy (USNB). Data are lacking on the value of this approach in identifying cases that fall outside Z11 guidelines. We studied 988 consecutive patients with invasive breast cancers who underwent operation including axillary surgery in 2010-2011. Preoperative axillary ultrasonography (AUS) was performed in 92% and breast/axillary magnetic resonance imaging (MRI) in 51%; 82 (33.5%) of 245 patients with suspicious lymph nodes (LN) were USNB-positive. Regarding nodal status, AUS, MRI, and USNB had negative and positive predictive values of 78%, 76%, 70% and 54%, 58%, 100%, respectively. AUS/MRI visualization of one versus multiple abnormal LNs visualized predicted >2LN+ on final pathology (13.5%/15.1% % vs 30.8%/32.6%, P 2LN+, P = .001. In our contemporary series, preoperative AUS±USNB streamlined surgical care for 29% of node-positive patients. Two-thirds of T1/T2 USNB-LN+ patients with multiple AUS-suspicious LNs had >2LN+, suggesting they should undergo ALND without SLNB. AUS±USNB helps identify node-positive breast cancer patients who fall outside Z11 guidelines. Copyright © 2013 Mosby, Inc. All rights reserved.

    Objective: to evaluate the potential influence of trans axillary augmentation mammoplasty on future detection of sentinel lymph node. Materials and methods: prospective controlled study where 22 patients were selected and divided into two groups (post-mammoplasty and control) corresponding to 43 breasts (22 in the post-mammoplasty group and 21 in the control group) evaluated by lymphoscintigraphy immediately after periareolar {sup 99m}Tc-phytate injections. In the statistical analysis, p values < 0.05 were considered as significant. Results: all the breasts in the post-mammoplasty group presented lymphatic drainage to the axillary chain, with no difference as compared with the control group (p 0.488). The average number of hot lymph nodes was 1.27 {+-} 0.46 in the post-mammoplasty group, and 1.33 {+-} 0.58 in the control group (p = 0.895). The mean time required to visualize the first lymph node was 3.14 {+-} 4.42 minutes in the post mammoplasty group, and 5.48 {+-} 5.06 minutes in the control group (p 0.136). Conclusion: transaxillary augmentation mammoplasty did not affect the future detection of sentinel lymph node. (author)

    Purpose: To investigate lymphatic drainage as measured by lymphoscintigraphy in the arms of patients undergoing either sentinel lymph node biopsy (SNB) or axillary lymph node dissection (ALND). Material and Methods: From January 2001 to December 2002, 30 patients with unilateral invasive breast carcinoma underwent breast-conserving surgery with SNB and 30 patients with ALND. All patients received radiotherapy to the breast. Lymphoscintigraphy was performed, and skin circulation, skin temperature, and arm volume were measured 2-3 years after radiotherapy. Results: None of the 30 patients who underwent SNB showed any clinical manifestation of lymphedema. Of the 30 patients undergoing ALND, six (20%) had clinical lymphedema, with an arm volume that was >10% larger on the operated than on the non-operated side (P<0.01). Scintigraphically, visual analysis revealed lymphatic dysfunction in three patients, manifested as forearm dermal back flow. Two of these patients also had an increased arm volume. Quantitative analysis showed no differences between the groups, apart from a smaller amount of isotope in the axilla in the ALND group. There was no difference in skin circulation or skin temperature. Conclusion: Our study shows that lymph drainage in the operated arm compared with the non-operated arm was less affected by SNB than by ALND, and that morbidity associated with SNB was lower than with ALND. However, the results do not confirm our hypothesis that lymphoscintigraphy can reveal differences in lymph circulation that are not evident clinically in the form of manifest lymphedema. The most sensitive clinical method of assessing lymph drainage seems to be measurement of arm volume

    The American College of Surgeons Oncology Group (ACOSOG) Z0011 trial reported that axillary lymph node dissection (ALND) did not change the recurrence and overall survival (OS) rates in patients with lumpectomy and one to two positive nodes detected by sentinel lymph node biopsy (SLNB). The aim of this study was to determine whether patients with mastectomy and pathological N1 disease found by SLNB could forego ALND. This is a retrospective study of 214 patients diagnosed with primary invasive breast cancer who were treated by mastectomy and lymph node staging surgery (SLNB or ALND) at the Revlon/UCLA Breast Center between January 2002 and December 2010. Patients with pathological N1 disease were separated by their first nodal surgery into SLNB (subgroups: observation, radiation, and additional ALND with or without radiation) and ALND groups (subgroups: ALND with or without radiation). After a median follow-up of 43.6 months, the OS and systemic relapse-free survival (RFS) rate of the radiation group and additional ALND group were significantly better than the observation group (p = 0.031 and 0.046, respectively). Human epidermal growth factor receptor 2 (HER2) expression was found to predict OS and patients' age, histological grade and HER2 expression predicted systemic recurrence. Compared with the SLNB group, pain (p = 0.021) and lymphedema (p = 0.043) occurred more frequently in the ALND group. Radiation was as effective as ALND in patients with mastectomy and N1 disease for OS and RFS rates, yet radiation after SLNB had fewer side effects than ALND. SLNB followed by radiation could replace ALND in patients with mastectomy and pathological N1 breast cancer identified by SLNB.

    Two murine monoclonal antibodies that react with human breast cancer (3E1.2 and RCC-1) were labelled with {sup 131}iodine, and the radiolabelled antibody was injected into 40 patients, 36 of whom had breast cancer and the remaining four of whom had fibroadenoma (the normal, contralateral axilla was used as a control). Immunoscintigraphy had an overall sensitivity of 33% (23% with {sup 131}I-3E1.2 and 5% with {sup 131}I-RCC-1) for the detection of lymph node metastases and a specificity of 63% (67% with {sup 131}I-3E1.2 and 60% with {sup 131}I-RCC-1) with problems of non-specific uptake by presumably normal lymph nodes. The results of immunoscintigraphy obtained with {sup 131}I-RCC-1 (IgG) were superior to {sup 131}I-3E1.2 (IgM) although the accuracy of immunoscintigraphy using {sup 131}I-RCC-1 (56%) was not much better than preoperative clinical assessment (50%). However, there were cases when immunoscintigraphy using radiolabelled antibody (IgM or IgG) detected axillary lymph node metastases not suspected by clinical examination. Thus it appears that while immunoscintigraphy may be a useful adjunct to preoperative clinical assessment and is simple and safe, a major improvement in its accuracy is needed before it can replace axillary dissection and histological examination in the accurate staging of axilla in breast cancer.

    The objective of this study was to investigate the role of post-mastectomy radiotherapy in breast carcinoma patients with a tumor size of 5 cm or smaller (T1-2) and 1-3 axillary lymph node(s) metastasis (N1). We retrospectively reviewed the file records of 575 patients receiving radiotherapy (452 patients) and not receiving radiotherapy (123 patients). In the whole series, locoregional recurrence-free survival was significantly better in patients receiving radiotherapy compared with patients not receiving radiotherapy (P 0.25 and in T2N1 breast carcinoma patients with a lymph node ratio of >0.08. In patients with a lymph node ratio equal to or less than these ratios, post-mastectomy radiotherapy could be omitted to avoid radiotherapy-related risks. (author)

    INTRODUCTION: Recent decades have seen a significant shift towards conservative management of the axilla. Increasingly, immunohistochemical analysis of sentinel nodes leads to the detection of small tumour deposits, the significance of which remains uncertain. The aims of this study are to examine patients whose sentinel lymph nodes are positive for macro-metastasis, micro-metastasis or isolated tumour cells (ITCs) and to determine the rate of further nodal disease after axillary lymph node dissection (ALND). METHODS: A retrospective analysis of all patients undergoing a sentinel lymph node biopsy (SLNB) between January 2007 and December 2010 in a tertiary referral breast unit was performed. Patients who underwent an axillary lymph node dissection for macro-metastasis, micro-metastasis or ITCs were identified. Demographics, histological data and the rate of further axillary disease were examined. RESULTS: In total, 664 breast cancer patients attended the symptomatic breast unit during the study period, 360 of whom underwent a SLNB. Seventy patients had a SLNB positive for macro-metastasis. All of these patients underwent ALND. A positive SLNB with either micro-metastasis or ITCs was identified in 58 patients. Only 41 of the 58 patients went on to have an ALND, due primarily to variations in surgeons\\' preferences. Nineteen patients with micro-metastasis underwent an ALND. Four patients had further axillary disease (21%). Twenty-two patients had ITCs identified, of whom only one had further disease (4.5%). No statistically significant difference was found between the two groups in terms of tumour size, grade, lymphovascular invasion or oestrogen receptor status. CONCLUSION: ALND should be considered in patients with micro-metastasis at SLNB. It should rarely be employed in the setting of SLNB positive for ITCs.

    In breast cancer, the number of lymph node metastases is the strongest predictor of outcome. However, histopathology may underestimate the frequency of metastasis. Here we compare automated molecular detection of cytokeratin 19 mRNA by one-step nucleic acid amplification (OSNA) with histopathology of single tissue sections for the staging of axillary lymph nodes in patients with breast cancer. Axillary lymph nodes were collected from 55 patients with primary breast cancer and sentinel lymph node (SLN) metastases. The central 1-mm portion of each node was processed for hematoxylin-eosin staining, and the remaining tissue was analyzed by OSNA. According to OSNA, histopathology misclassified 41.8% of patients as negative for axillary node metastasis (P=0.007). Of the individual nodes considered negative by histopathology, 4.5% contained micrometastases and 2.5% contained macrometastases according to OSNA. Furthermore, 80% of micrometastases identified by histopathology were reclassified as macrometastases by OSNA. Histopathology failed to identify 81.1% of nodes shown to contain metastasis by OSNA. However, OSNA yielded no false-negative results. On the basis of OSNA results, 3 patients were reclassified to a higher pathologic stage. The number of SLN and non-SLN metastases was unrelated according to OSNA (P=0.891). These results show that, compared with molecular detection, histopathology of single tissue sections significantly underestimates the frequency of axillary node metastases. We discuss the implications of these findings in light of current recommendations on the staging of breast cancer.

However, ALND remains standard management of the axilla when a tumor-positive sentinel lymph node is identified.Methods: We identified 460 patients with breast cancer (clinically T1/T2N0M0 from the database for 1999–2004. Patient age ranged from 26 to 81 (median 50 years. Patients who underwent mastectomy or breast-conserving surgery with or without ALND were compared for regional recurrence, disease-free survival, and overall survival.Results: Patients with ALND (n = 308 were compared with the no ALND group (n = 152. Five-year overall survival and disease-free survival were not significantly different between the two groups, while there was a significant difference between them for regional recurrence. Of the 152 patients who did not undergo axillary dissection, four developed ipsilateral axillary disease, most of whom were rescued by delayed axillary dissection. Further, the criterion for identifying lymphedema was used, ie, a 2 cm circumferential change at any measured location. As a result, the incidence of lymphedema in the ALND group was 12.7%, while it was not seen in the non ALND group.Conclusion: There is a possibility that ALND may be omitted for cT1/T2N0M0 breast cancer through a combination of hormone therapy and adjuvant chemotherapy.Keywords: breast cancer, axillary lymph node dissection

    Recent studies have demonstrated low regional recurrence rates in early-stage breast cancer omitting axillary lymph node dissection (ALND) in patients who have positive nodes in sentinel lymph node dissection (SLND). This finding has triggered an active discussion about the effect of radiotherapy within this approach. The purpose of this study was to analyze the dose distribution in the axilla in standard tangential radiotherapy (SRT) for breast cancer and the effects on normal tissue exposure when anatomic level I-III axillary lymph node areas are included in the tangential radiotherapy field configuration. We prospectively analyzed the dosimetric treatment plans from 51 consecutive women with early-stage breast cancer undergoing radiotherapy. We compared and analyzed the SRT and the defined radiotherapy (DRT) methods for each patient. The clinical target volume (CTV) of SRT included the breast tissue without specific contouring of lymph node areas, whereas the CTV of DRT included the level I-III lymph node areas. We evaluated the dose given in SRT covering the axillary lymph node areas of level I-III as contoured in DRT. The mean V{sub D95} {sub %} of the entire level I-III lymph node area in SRT was 50.28 % (range, 37.31-63.24 %), V{sub D45} {sub Gy} was 70.1 % (54.8-85.4 %), and V{sub D40} {sub Gy} was 83.5 % (72.3-94.8 %). A significant difference was observed between lung dose and heart toxicity in SRT vs. DRT. The V{sub 20} {sub Gy} and V{sub 30} {sub Gy} of the right and the left lung in DRT were significantly higher in DRT than in SRT (p < 0.001). The mean heart dose in SRT was significantly lower (3.93 vs. 4.72 Gy, p = 0.005). We demonstrated a relevant dose exposure of the axilla in SRT that should substantially reduce local recurrences. Furthermore, we demonstrated a significant increase in lung and heart exposure when including the axillary lymph nodes regions in the tangential radiotherapy field set-up. (orig.)

    Despite the recent changes in the treatment of the axilla in selected breast cancer patient, positive sentinel lymph node (SLN) in patients undergoing mastectomy still necessitates axillary lymph node dissection (ALND). In invasive lobular carcinoma (ILC), pre-operative detection of the lymph node metastasis may be demanding due to its unique morphology. The aim of this study was to examine the benefit of preoperative axillary ultrasound (AUS), ultrasound-guided fine-needle aspiration biopsy (US-FNAB), and intra-operative imprint cytology (IIC), in order to avoid two-stage axillary surgery in patients with ILC undergoing mastectomy. The object of this study were 102 patients (median age 52, range 34-73 years) with clinically non-suspicious axilla in whom 108 mastectomies were performed after a pre-operative AUS investigation. Whenever a metastasis was detected in a sentinel lymph node, ALND was done. Reports of the pre-operative AUS investigation, US-FNAB, and IIC were compared with definitive histopathological reports of surgical specimens. In 46 cases lymph node metastases were diagnosed. AUS suspicious lymph nodes were found in 29/108 cases and histopathology confirmed metastases in 22/30 cases. US-FNAB was performed in 29 cases with AUS suspicious lymph nodes. Cytology proved metastases in 11/29 cases. Histopathology confirmed metastases in 10/11 cases with only isolated tumor cells found in one case. IIC investigation was performed in 63 cases and in 10/27 cases metastases were confirmed by histopathology. Pre-operative AUS, US-FNAB, and/or IIC investigation enabled ALND during a single surgical procedure in 20/46 patients with metastases in lymph nodes. Pre-operative AUS, US-FNAB, and/or IIC are/is beneficial in patients with ILC planned for mastectomy in order to decrease the number of two stage axillary procedures.

    The early results of the American College of Surgeons Oncology Group (ACOSOG) Z0011 trial demonstrated no difference in locoregional recurrence for patients with positive sentinel lymph nodes (SLNs) randomized either to axillary lymph node dissection (ALND) or sentinel lymph node dissection (SLND) alone. We now report long-term locoregional recurrence results. ACOSOG Z0011 prospectively examined overall survival of patients with SLN metastases undergoing breast-conserving therapy randomized to undergo ALND after SLND or no further axillary specific treatment. Locoregional recurrence was prospectively evaluated and compared between the groups. Four hundred forty-six patients were randomized to SLND alone and 445 to SLND and ALND. Both groups were similar with respect to age, Bloom-Richardson score, Estrogen Receptor status, adjuvant systemic therapy, histology, and tumor size. Patients randomized to ALND had a median of 17 axillary nodes removed compared with a median of only 2 SLNs removed with SLND alone (P alone arm (P = 0.28). Ten-year cumulative locoregional recurrence was 6.2% with ALND and 5.3% with SLND alone (P = 0.36). Despite the potential for residual axillary disease after SLND, SLND without ALND offers excellent regional control for selected patients with early metastatic breast cancer treated with breast-conserving therapy and adjuvant systemic therapy.

    Full Text Available Purpose: Lysosome-associated protein transmembrane-4 beta (LAPTM4B is associated with the prognosis of several human malignancies. In this study, the role of LAPTM4B in the metastatic potential of breast cancer (BC and its underlying molecular mechanisms were investigated. Methods: The relationship between LAPTM4B expression and axillary lymph node metastasis was determined in 291 BC specimens by immunohistochemistry. The expression of LAPTM4B in paired BC cells was overexpressed and inhibited to analyse the role of LAPTM4B in the aggressiveness of BC. Cell proliferation, migration and invasion were assessed in vitro. Metastasis-related protein levels were detected through Western blot. Results: Immunohistochemical staining demonstrated that high expression level of LAPTM4B was independently associated with axillary lymph node metastasis (odds ratio=2.428; 95%CI=1.333- 4.425; P=0.004. The LAPTM4B inhibition in MCF-7 cells inhibited cell proliferation, migration, invasion, and resulted in simultaneous downregulation of phosphorylated N-cadherin, vimentin, and upregulation of E-cadherin. By contrast, the LAPTM4B overexpression promoted cell proliferation, migration, invasion, and led to simultaneous upregulation of N-cadherin, vimentin, and downregulation of E-cadherin in T47D cells. Conclusions: High expression level of LAPTM4B predicts tumor metastatic potential in patients with BC. Our results provide the first evidence of the role of LAPTM4B as an Epithelial-mesenchymal transition (EMT inducer that promotes aggressiveness in BC cells.

    Inclusions of ectopic breast tissue in axillary lymph nodes are reported very infrequently and typically are only identified microscopically as an incidental finding. Furthermore the development of a benign proliferative lesion in the form of an intraductal papilloma from intranodal ectopic breast tissue is an extremely rare phenomenon with only three previous cases reported. This report describes an unusual and rare case of an intraductal papilloma arising in an axillary lymph node of a patient known to have the human immunodeficiency virus. A 40-year-old Black African woman underwent excision of an enlarged palpable axillary lymph node. In the preceding 7 years she had received at least six separate surgical excisions to her ipsilateral breast for papillomatosis. The last surgical intervention was performed 1 year prior to presentation with an enlarged axillary lymph node. Histological examination of her axillary lymph node revealed a papillomatous proliferative epithelial lesion within an apparent encompassing duct, resembling a mammary intraductal papilloma. In the surrounding lymphoid tissue small groups of duct-like structures were additionally noted. Immunostaining with a panel of myoepithelial markers in conjunction with oestrogen receptor produced a mixed heterogeneous staining pattern in both the papillomatous lesion and the peripheral duct-like structures. This confirmed the diagnosis of a benign intraductal papilloma within an axillary lymph node, considered to have arisen from ectopic breast tissue. This case demonstrates that intranodal ectopic breast tissue has the potential to undergo benign proliferative change albeit extremely rarely. Therefore this possibility must be considered to ensure the correct diagnosis is made. In addition, to the best of our knowledge, this is the first case report which has described recurrent intraductal papillomas and the subsequent development of an intraductal papilloma within an ipsilateral axillary lymph node, in

    Although axillary surgery is still considered to be a fundamental part of the management of early breast cancer, it may no longer be necessary either as treatment or as a guide to adjuvant treatment. The authors conducted a single-center randomized trial (INT09/98) to determine the impact of avoiding axillary surgery in patients with T1N0 breast cancer and planning chemotherapy based on biological factors of the primary tumor on long-term disease control. From June 1998 to June 2003, 565 patients aged 30 years to 65 years with T1N0 breast cancer were randomized to either quadrantectomy with (QUAD) or without (QU) axillary lymph node dissection; a total of 517 patients finally were evaluated. All patients received radiotherapy to the residual breast only. Chemotherapy for patients in the QUAD treatment arm was determined based on lymph node status, estrogen receptor status, and tumor grade. Chemotherapy for patients in the QU treatment arm was based on estrogen receptor status, tumor grade, and human epidermal growth factor receptor 2 and laminin receptor status. Overall survival (OS) was the primary endpoint. Disease-free survival (DFS) and rate and time of axillary lymph node recurrence in the QU treatment arm were the secondary endpoints. After a median follow-up of >10 years, the estimated adjusted hazards ratio of the QUAD versus QU treatment arms for OS was 1.09 (95% confidence interval, 0.59-2.00; P = .783) and was 1.04 (95% confidence interval, 0.56-1.94; P = .898) for DFS. Of the 245 patients in the QU treatment arm, 22 (9.0%) experienced axillary lymph node recurrence. The median time to axillary lymph node recurrence from breast surgery was 30.0 months (interquartile range, 24.2 months-73.4 months). Patients with T1N0 breast cancer did not appear to benefit in terms of DFS and OS from immediate axillary lymph node dissection in the current randomized trial. The biological characteristics of the primary tumor appear adequate for guiding adjuvant

    Full Text Available Background: Preoperative ultrasound (US and eventually US-guided fine-needle aspiration cytology (FNAC of suspicious axillary lymph nodes (ALN is a standard procedure in the work-up of suspicious breast lesions. Preoperative US FNAC may prevent sentinel node biopsy (SNB procedure in 24-30% of patients with early stage breast carcinoma. The aim of this study was to evaluate the institutional results of this preoperative diagnostic procedure. Materials and Methods: A total of 182 cases of preoperative FNAC of suspicious ALN where retrieved from the pathology files. The results were compared with the final histology and staging. False negative (FN FNAC cases were reviewed and possibly missed metastatic cases (2 were immunostained with the epithelial marker AE1/AE3. Results: There were no false positives, whereas 16 cases were FN. In all but one case the FN′s represented sampling error. Half of the 16 FN cases in this series were macrometastases. Discussion: About 83% of the preoperatively aspirated cases were N+, indicating that a radiologically suspicious ALN has a very high risk of being metastatic. Preoperative US guided FNAC from radiologically suspicious ALN is highly efficient in detecting metastases. Depending on national guidelines, a preoperative, positive ALN FNAC might help to stratify the patients as to SNB and/or ALN dissection.

    A 48-year-old woman with invasive ductal carcinoma of the left breast underwent breast-conserving surgery and axillary dissection; 19 months after surgery, she developed local recurrence. Subsequently, she underwent mastectomy and received endocrine therapy and chemotherapy. At 47 years of age, she developed pleural metastasis, which directly invaded the vertebrae as well as the right supraclavicular and right axillary lymph nodes. In addition, liver metastasis was observed. To avoid acute transverse myelopathy, the patient received radiation therapy to the vertebrae and the right supraclavicular and right axillary lymph nodes followed by paclitaxel plus bevacizumab administration. After 2 courses of paclitaxel plus bevacizumab, we observed a remarkable shrinkage of the vertebral tumor, and skin necrosis was observed in the right supraclavicular and right axillary region; in contrast, the liver metastasis had increased in size. After discontinuation of the combination therapy, the patient died of blood loss from the axillary skin defect. This wound healing complication might have arisen because of the synergistic effects of paclitaxel plus bevacizumab and irradiation. (author)

    Purpose: The purpose of this study was to identify the axillary lymph nodes on pretreatment diagnostic computed tomography (CT) of the chest to determine their position relative to the anatomic axillary borders as defined by the Radiation Therapy Oncology Group (RTOG) breast cancer atlas for radiation therapy planning. Methods and Materials: Pretreatment diagnostic CT chest scans available for 30 breast cancer patients with clinically involved lymph nodes were fused with simulation CT. Contouring of axillary levels I, II, and III according to the RTOG guidelines was performed. Measurements were made from the area of distal tumor to the anatomic borders in 6 dimensions for each level. Results: Of the 30 patients, 100%, 93%, and 37% had clinical involvement of levels I, II, and III, respectively. The mean number of lymph nodes dissected was 13.6. The mean size of the largest lymph node was 2.4 cm. Extracapsular extension was seen in 23% of patients. In 97% of patients, an aspect of the involved lymph node lay outside of the anatomic border of a level. In 80% and 83% of patients, tumor extension was seen outside the cranial (1.78 ± 1.0 cm; range, 0.28-3.58 cm) and anterior (1.27 ± 0.92 cm; range, 0.24-3.58 cm) borders of level I, respectively. In 80% of patients, tumor extension was seen outside the caudal border of level II (1.36 ± 1.0 cm, range, 0.27-3.86 cm), and 0% to 33% of patients had tumor extension outside the remaining borders of all levels. Conclusions: To cover 95% of lymph nodes at the cranial and anterior borders of level I, an additional clinical target volume margin of 3.78 cm and 3.11 cm, respectively, is necessary. The RTOG guidelines may be insufficient for coverage of axillary disease in patients with clinical nodal involvement who are undergoing neoadjuvant chemotherapy, incomplete axillary dissection, or treatment with intensity modulated radiation therapy. In patients with pretreatment diagnostic CT chest scans, fusion with

    Background Most patients with early-stage breast cancer have clinically negative lymph nodes (LNs). However, 15-20% of patients have axillary nodal metastasis based on the sentinel LN biopsy. Purpose To assess whether ultrasound (US) features of a primary tumor are associated with axillary LN metastasis in patients with clinical T1-T2N0 breast cancer. Material and Methods This retrospective study included 138 consecutive patients (median age = 51 years; age range = 27-78 years) who underwent breast surgery with axillary LN evaluation for clinically node-negative T1-T2 breast cancer. Three radiologists blinded to the axillary surgery results independently reviewed the US images. Tumor distance from the skin and distance from the nipple were determined based on the US report. Association between US features of a breast tumor and axillary LN metastasis was assessed using a multivariate logistic regression model after controlling for clinicopathologic variables. Results Of the 138 patients, 28 (20.3%) had nodal metastasis. At univariate analysis, tumor distance from the skin ( P = 0.019), tumor size on US ( P = 0.023), calcifications ( P = 0.036), architectural distortion ( P = 0.001), and lymphovascular invasion ( P = 0.049) were associated with axillary LN metastasis. At multivariate analysis, shorter skin-to-tumor distance (odds ratio [OR] = 4.15; 95% confidence interval [CI] = 1.01-16.19; P = 0.040) and masses with associated architectural distortion (OR = 3.80; 95% CI = 1.57-9.19; P = 0.003) were independent predictors of axillary LN metastasis. Conclusion US features of breast cancer can be promising factors associated with axillary LN metastasis in patients with clinically node-negative early-stage breast cancer.

    The purpose of this article was to examine the relationship between age and lymph node ratio (LNR, number of positive nodes divided by number of examined nodes), and to determine their effects on breast cancer (BC) and overall mortality. Women aged ≥50 years, diagnosed in 1988-1997 with a unilateral histologically confirmed T1-T2 node positive surgically treated primary nonmetastatic BC, were selected from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER). Generalized Additive Models for Location Scale and Shape (GAMLSS) were used to evaluate the age-LNR relationship. Cumulative incidence functions and multivariate competing risks analysis based on model selection by the Bayesian Information Criterion (BIC) were used to examine the effect of age and LNR on mortality. Low LNR was defined as ≤0.20, mid-LNR 0.21-0.65, and high LNR >0.65. GAMLSS showed a nonlinear LNR-age relationship, increasing from mean LNR 0.26-0.28 at age 50-70 years to 0.30 at 80 years and 0.40 at 90 years. Compared with a 9.8% [95% confidence interval (CI) 8.8%-10.8%] risk of BC death at 5 years in women aged 50-59 years with low LNR, the risk in women ≥80 years with low LNR was 12.6% [95% CI 10.1%-15.0%], mid-LNR 18.1% [13.9%-22.1%], high LNR 29.8% [22.7%-36.1%]. Five-years overall risk of death increased from 40.8% [37.5%-43.9%] by low LNR to 67.4% [61.4%-72.4%] by high LNR. The overall mortality hazard ratio for age ≥80 years with high LNR was 7.49 [6.54-8.59], as compared with women aged 50-59 years with low LNR. High LNR combined with older age was associated with a threefold increased risk of BC death and a sevenfold increased hazard ratio of overall mortality.

    To analyze the rate of axillary recurrences (AR) in patients with early breast cancer who had not undergone an axillary node dissection (ALND) because of a negative sentinel lymph node biopsy (SLNB). The study includes 173 patients operated on for breast cancer and selective node biopsy. In 32 patients the SLNB was positive and undergone subsequent ALND. We followed up 141 patients with negative SLNB without LDN, with a median follow up of 55 months (range 74-36). The detection rate of SLN was of 99.42%. After a median follow-up of 4.5 years, there were no axillary recurrences. Two patients developed local recurrence, other two patients developed distant metastases and four patients developed a metachronous tumor. Four patients died, none of them because of breast cancer. The results obtained support the SLNB as an accurate technique in the axillary stratification of patients with breast cancer, offering in the cases of negative SLNB a safe axillary control after 4.5 year follow-up.

    Full Text Available The purpose of this study was to assess the usefulness of HER2 levels in ultrasonographically guided fine-needle aspiration biopsy (US-FNA aspirates of axillary lymph nodes (ALNs in the determination of lymph node metastasis or the characterization of primary breast cancer, and to correlate the HER2 levels in US-FNA aspirates (FNA-HER2s of metastatic ALNs with the HER2 statuses of corresponding primary breast cancers. An institutional review board approved the study. Between January and October 2010, 164 patients with 167 ALNs examined by US-FNA were included. FNA-HER2s of ALNs were measured by chemiluminescence immunoassay, and they were correlated with cytologic/final diagnoses. Receiver operating characteristics (ROC curve analysis was performed to evaluate the diagnostic ability to differentiate benign and metastatic ALNs. Additionally, FNA-HER2s of metastatic ALNs were correlated with HER2 status and other clinicopathologic variables of the primary breast cancers. Among the 167 ALNs, 138 were metastatic and 29 were benign. The mean FNA-HER2 (6.3 ng/ml of metastatic ALNs was higher than that of benign ALNs. All 29 benign ALNs showed no measurable value of FNA-HER2 (0.0 ng/ml. The area under the ROC curves of FNA-HER2 of ALNs was 0.679 for the diagnosis of ALN metastasis. The FNA-HER2 statuses of 108 metastatic ALNs (79.4% were concordant with the HER2 statuses of the corresponding primary breast cancers. In a subgroup analysis of HER2-positive cancers with ALN metastasis, distant metastasis was significantly associated with FNA-HER2-negativity of metastatic ALNs (P = 0.04. Although FNA-HER2 of ALNs did not improve the diagnostic performance of FNA cytology in preoperative diagnosis of ALN metastasis of overall patients, FNA-HER2-positive metastatic ALNs were significantly associated with HER2-positivity of primary breast cancers. Additionally, FNA-HER2 analysis of ALN may help to develop more personalized treatment protocol for breast

    Nomograms are a standard computational tool to predict the likelihood of an outcome using multiple available patient features. We have developed a more powerful data mining methodology, to predict axillary lymph node (AxLN) metastasis and response to neoadjuvant chemotherapy (NAC) in primary breast cancer patients. We developed websites to use these tools. The tools calculate the probability of AxLN metastasis (AxLN model) and pathological complete response to NAC (NAC model). As a calculation algorithm, we employed a decision tree-based prediction model known as the alternative decision tree (ADTree), which is an analog development of if-then type decision trees. An ensemble technique was used to combine multiple ADTree predictions, resulting in higher generalization abilities and robustness against missing values. The AxLN model was developed with training datasets (n=148) and test datasets (n=143), and validated using an independent cohort (n=174), yielding an area under the receiver operating characteristic curve (AUC) of 0.768. The NAC model was developed and validated with n=150 and n=173 datasets from a randomized controlled trial, yielding an AUC of 0.787. AxLN and NAC models require users to input up to 17 and 16 variables, respectively. These include pathological features, including human epidermal growth factor receptor 2 (HER2) status and imaging findings. Each input variable has an option of "unknown," to facilitate prediction for cases with missing values. The websites developed facilitate the use of these tools, and serve as a database for accumulating new datasets.

    Aim: To compare the acceptability, safety, and feasibility of vacuum-assisted biopsy (VAB) and core needle biopsy (CNB) of axillary lymph nodes in women with breast cancer. Materials and methods: This parallel, non-blinded, randomised study was approved by the National Research Ethics Service. Following written informed consent, women with abnormal appearing axillary lymph nodes and radiologically malignant breast masses were randomised 1:1 to lymph node sampling under local anaesthetic with either 14 G CNB or 13 G VAB in a single UK centre. Primary outcomes were study uptake rate and patient willingness to undergo a repeat procedure if necessary. Procedure duration, immediate and post-procedure pain scores, diagnostic yield, complications, and surgical histopathology were recorded. Results: Ninety-five women were approached; 81 (85.3%) consented and were randomised. Forty underwent CNB; 40 underwent VAB; one was excluded. Median age was 57 years. The median procedure time was 2 minutes for both techniques. The median number of samples obtained was three for CNB and four for VAB. Median pain scores for the procedure and first 3 days were 1/10 and 1/10 for CNB and 1/10 and 2/10 for VAB (p=0.11 and 0.04). More women were prepared to undergo repeat CNB compared to VAB, but the difference was not significant (38/39 versus 33/39; p=0.11). Two patients developed a haematoma after VAB. One CNB and six VABs failed to yield adequate tissue (p=0.11), but the sensitivity was similar at 79% and 78%. Conclusion: Study uptake was high. Acceptability of the two procedures was similar, but VAB was associated with more post-procedure pain. The sensitivity appears to be similar. - Highlights: • Vacuum biopsy of axillary lymph nodes can be performed rapidly. • Post-procedure pain was slightly higher in women who underwent vacuum biopsy. • The inadequate yield rate of vacuum biopsy may be higher than that for core biopsy. • Sensitivity of 13-gauge vacuum biopsy and 14-gauge

    Full Text Available The American College of Surgeons Oncology Group (ACOSOG Z0011 trial demonstrated no difference in local-regional recurrence (LRR, disease-specific survival (DSS or overall survival (OS for sentinel lymph node dissection (SLND and completion axillary lymph node dissection (ALND among patients undergoing breast-conserving therapy for clinical T1-T2, N0 breast cancer with 1 or 2 positive SLNs. However, Only 7% of study participants had invasive lobular carcinoma (ILC. Because ILC has a different pattern of metastases, frequently presenting as small foci requiring immunohistochemistry for detection, the applicability of ACOSOG Z0011 trial data to ILC patients is unclear.We identified all ILC patients in the Surveillance, Epidemiology, and End Results (SEER database (1998-2009 who met the ACOSOG Z0011 eligibility criteria. Patients were evaluated on the basis of the extent of axillary surgery (SLND alone or ALND, and the clinical outcomes of these 2 groups were compared.1269 patients (393 SLND and 876 ALND were identified from the SEER database. At a median follow-up time of 71 months, there were no differences in OS or disease-specific survival between the two groups.SLND alone may result in outcomes comparable to those achieved with ALND for patients with early-stage ILC who meet the ACOSOG Z0011 eligibility criteria.

    The American College of Surgeons Oncology Group trial Z0011 was a prospective, randomized, multicenter trial comparing overall survival between patients with positive sentinel lymph nodes (SLNs) who did and did not undergo axillary lymph node dissection (ALND). The current study compares complications associated with SLN dissection (SLND) plus ALND, versus SLND alone. From May 1999 to December 2004, 891 patients were randomly assigned to SLND + ALND (n = 445) or SLND alone (n = 446). Information on wound infection, axillary seroma, paresthesia, brachial plexus injury (BPI), and lymphedema was available for 821 patients. Adverse surgical effects were reported in 70% (278 of 399) of patients after SLND + ALND and 25% (103 of 411) after SLND alone (P alone group. At 1 year, lymphedema was reported subjectively by 13% (37 of 288) of patients after SLND + ALND and 2% (six of 268) after SLND alone (P alone. Lymphedema was more common after SLND + ALND but was significantly different only by subjective report. The use of SLND alone resulted in fewer complications.

    Full Text Available Background. Breast lumps have varied pathology, and there are different techniques to prove the diagnosis. The aim of the present study is to analyze the role of fine needle aspiration cytology (FNAC of the breast lesions at our center. Methods. We had retrospectively analysed 854 patients who underwent FNAC for primary breast lumps and 190 patients who underwent FNAC for an axillary lymph node in the year 2010. Results. Of 854 patients, histological correlation was available in 723 patients. The analysis was done for 812 patients as medical records were not available for 42 patients. FNAC was false negative in seven cases; 2 cases of phyllodes were reported as fibroadenoma, and 5 cases of carcinoma were diagnosed as atypical hyperplasia. The sensitivity, specificity, and false negative value of FNAC in diagnosing breast lumps were 99% (715/723, 100%, and 1%, respectively. Of 190 patients for whom FNAC was performed for axilla, 170 had proven to have axillary lymph node metastases, and the rest had reactive hyperplasia or inflammatory cells. Conclusions. FNAC is rapid, accurate, outpatient based, and less complicated procedure and helps in diagnosis of breast cancer, benign diseases, and axillary involvement in experienced hands with less chance of false results.

    The aim of this study was to define the impact of the presence of axillary nodal metastases on lymphatic mapping and sentinel lymph node (SLN) identification rate in patients with early breast cancer. Two hundred and forty-six lymphatic mapping procedures were performed with both labelled nanocolloid and blue dye, followed by SLN biopsy and/or complete axillary dissection. The following parameters were recorded: patient's age, tumour laterality and location, tumour size, tumour histology, tumour stage, tumour grade, lymphovascular invasion, radiotracer injection site (subdermal-peritumoural/peri-areolar), SLN visualisation at lymphoscintigraphy, SLN metastases (presence/absence, size) and other axillary metastases (presence/absence, number). Discriminant analysis was used to analyse the data. SLNs were identified by labelled nanocolloid alone in 94.7% of tumours, by blue dye alone in 93.5% and by the combined technique in 99.2%. Discriminant analysis showed the gamma probe SLN identification rate to be significantly limited by the presence of axillary nodal metastases. In particular, the size of SLN metastases and the number of other axillary metastases were the most important variables in reducing the gamma probe SLN identification rate (p=0.004 and p=0.002, respectively). On the other hand, high tumour grade was the only parameter limiting the blue dye SLN identification rate. The accuracy of lymphatic mapping with labelled nanocolloid is limited by the presence of axillary nodal metastases, and particularly by the degree of SLN tumoural invasion and the presence and number of other axillary nodal metastases. Neither of these elements seems to interfere with the blue dye identification rate. The combination of the two tracers maximises the SLN identification rate. (orig.)

    We explored the relations between PTEN/PI3K/AKT expression and clinicopathological characteristics and prognosis in breast cancer patients with and without axillary lymph node metastasis (LNM). Tissues and follow-up data from 142 patients with (LNM group) and 154 without (non-LNM group) metastases were collected. Expression of PTEN/PI3K/AKT was detected using immunohistochemistry staining. With axillary LNM, the positive rate of PTEN was reduced, whereas that of PI3K and AKT was increased. Expression of AKT was negatively correlated with PTEN expression but positively correlated with PI3K expression. Apparent correlations were detected between AKT and axillary LNM with a tumor size of 2 cm or less; between PTEN, PI3K, and AKT and axillary LNM in stage T1 or T2 breast cancer and invasive carcinoma of a nonspecial type; and between PTEN and AKT and axillary LNM of histologic grade I or II tumors and non-triple-negative breast cancer (all PPTEN-positive tumors was higher than that of patients with PTEN-negative lesions; whereas in the non-LNM group, the 5-year survival rate of patients with AKT-positive tumors was lower than that of patients with AKT-negative lesions (both PPTEN expression was an independent prognostic factor for patients with LNM; AKT expression, tumor diameter, pathologic grade, and pathologic type were independent prognostic factors for patients without LNM. In conclusion, TEN/PI3K/AKT proteins are related to the clinicopathological features and prognosis of breast cancer with axillary LNM. Copyright © 2016 Elsevier Inc. All rights reserved.

    To assess the differences in unintended regional nodal irradiation between free breathing (FB) and deep-inspiration breath-hold (DIBH) during tangential field irradiation. We randomly chose 32 patients from our database who underwent both DIBH and FB treatment planning. Contouring of the axillary lymph node levels (LI, LII, and LIII) was performed retrospectively according to the Radiation Therapy Oncology Group contouring atlas. We assessed the center of mass of each level and the planning target volume, as well as the dose distribution (Dmean, Dmedian, Dmax, Dmin, V30, and V40) in the lymph node levels I-III. Subsequently center of mass movement and dose changes due to deep inspiration treatment planning were calculated. All lymph node levels showed significant (Pinspiration breath-hold results in a significant dose reduction in level I. Only minor changes in dose distribution were recorded for levels II and III. Thus, DIBH seems to have an impact on unintended regional nodal irradiation as compared with FB. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available BACKGROUND ALND after breast cancer surgery is associated with considerable morbidity. We hypothesised- 1 The morbidity in patients undergoing SLN biopsy only is significantly lower compared with those after SLN and completion ALND level I and II; and 2 The intermediate survival rates, local and axillary recurrence rates were significantly equivalent in both the groups. MATERIALS AND METHODS Patients with early stage breast cancer (pT1 and pT2 ≤3 cm, cN0 were included between April 2010 and April 2016 in this prospective single centre study. All patients underwent SLN biopsy. In all patients with SLN macrometastases and most patients with SLN micrometastases (43 of 68 or isolated tumour cells (11 of 19, a completion ALND was performed. Postoperative morbidity was assessed based on a standardised protocol. RESULTS SLN biopsy alone was performed in 449 patients, whereas 210 patients underwent SLN and completion ALND. The median follow-ups were 31.0 and 29.5 months for the SLN and SLN and completion ALND groups, respectively. Intermediate-term follow-up information was available from 635 of 659 patients (96.4% of enrolled patients. The following results were found in the SLN versus SLN and completion ALND group- Presence of lymphoedema (3.5% vs. 19.1%, P <0.0001, impaired shoulder range of motion (3.5% vs. 11.3%, P <0.0001, shoulder/arm pain (8.1% vs. 21.1%, P <0.0001 and numbness (10.9% vs. 37.7%, P <0.0001. CONCLUSION The morbidity after SLN biopsy alone is not negligible, but significantly lower compared with ALND. The intermediate survival rates, local and axillary recurrence rates were equivalent in SLNB only and SLNB plus completion ALND groups.

    The aim of the present work was to analyse the impact of mild hypofractionated radiotherapy (RT) of infra-supraclavicular lymph nodes after axillary dissection on late toxicity. From 2007 to 2012, 100 females affected by breast cancer (pT1- T4, pN1-3, pMx) were treated with conservative surgery, Axillary Node Dissection (AND) and loco-regional radiotherapy (whole breast plus infra-supraclavicular fossa). Axillary lymph nodes metastases were confirmed in all women. The median age at diagnosis was 60 years (range 34–83). Tumors were classified according to molecular characteristics: luminal-A 59 pts (59 %), luminal-B 24 pts (24 %), basal-like 10 pts (10 %), Her-2 like 7 pts (7 %). 82 pts (82 %) received hormonal therapy, 9 pts (9 %) neo-adjuvant chemotherapy, 81pts (81 %) adjuvant chemotherapy. All patients received a mild hypofractionated RT: 46 Gy in 20 fractions 4 times a week to whole breast and infra-supraclavicular fossa plus an additional weekly dose of 1,2 Gy to the lumpectomy area. The disease control and treatment related toxicity were analysed in follow-up visits. The extent of lymphedema was analysed by experts in Oncological Rehabilitation. Within a median follow-up of 50 months (range 19–82), 6 (6 %) pts died, 1 pt (1 %) had local progression disease, 2 pts (2 %) developed distant metastasis and 1 subject (1 %) presented both. In all patients the acute toxicity was mainly represented by erythema and patchy moist desquamation. At the end of radiotherapy 27 pts (27 %) presented lymphedema, but only 10 cases (10 %) seemed to be correlated to radiotherapy. None of the patients showed a severe damage to the brachial plexus, and the described cases of paresthesias could not definitely be attributed to RT. We did not observe symptomatic pneumonitis. Irradiation of infra-supraclavicular nodes with a mild hypofractionated schedule can be a safe and effective treatment without evidence of a significant increase of lymphedema appearance radiotherapy related

    Purpose: The Utrecht MRI-linac (MRL) design enables new MR-guided radiotherapy (RT) approaches. This is a feasibility study for a single-fraction high dose (boost) to individual lymph nodes (LNs) in breast-cancer patients, after breast-conserving surgery (BCS) and hypofractionated whole-breast irradiation (WBI) with conventional axillary RT (AxRT). Methods: After written informed consent, 5 breast-cancer patients (cT1-3N0) were enrolled (NL500460.041.14 trial) and underwent 1.5T MRI in supine RT position, after BCS. Axillary levels, based on ESTRO guidelines, and organs-at-risk (OARs) – including lungs, chest wall, plexus and neurovascular bundle (NVB) – were delineated. Pseudo-CT scans (pCTs) were generated by HU bulk-assignment of water, lung, and air. With Monaco treatment-planning software (TPS Elekta), VMAT plans were generated for simultaneous WBI and AxRT, prescribing 16×2.66=42.56Gy (V95%>99% V107%<2cc). Two scenarios were considered: AxRT of levels I–II; AxRT of levels I–IV, depending on boost location. Per patient, 4 LNs with varying axillary locations were selected, delineated, and expanded to PTV with 2-mm margin. Using dedicated MRL TPS, accounting for magnetic-field effects, an IMRT 1×8.5Gy boost was simulated for each LN, to achieve a total target dose of 66Gy EQD2 (α/β=3.5Gy). WBI/ART doses and boost doses were added, and evaluated in EQD2. Results: For all scenarios, 1×8.5Gy boosts could be simulated within clinical constraints for a 66Gy total dose, in addition to WBI/AxRT. LN target coverage was excellent (V95%>95%, mean >8.5Gy). Additional dose to OARs was limited. Conclusion: Our study explored the concept of LN boosting using on-line MRI guidance. It is feasible to boost individual axillary LNs – with 2-mm margin – with an additional 1×8.5Gy, in all axillary levels, within clinical constraints. This may lead to more personalized RT approaches for patients with involved LNs and may reduce RT-induced toxicity, or the need for

    The concept of sentinel lymph node biopsy in breast cancer surgery is based on the fact that the tumour drains in a logical way via the lymphatic system, from the first to upper levels. Since axillary node dissection does not improve the prognosis of patients with breast cancer, sentinel lymph node biopsy might replace complete axillary dissection for staging of the axilla in clinically N0 patients. Sentinel lymph node biopsy would represent a significant advantage as a minimally invasive procedure, considering that about 70% of patients are found to be free from metastatic disease, yet axillary node dissection can lead to significant morbidity. Subdermal or peritumoural injection of small aliquots (and very low activity) of radiotracer is preferred to intratumoural administration, and 99m Tc-labelled colloids with most of the particles in the 100-200 nm size range would be ideal for radioguided sentinel node biopsy in breast cancer. The success rate of radioguidance in localising the sentinel lymph node in breast cancer surgery is about 97% in institutions where a high number of procedures are performed, and the success rate of lymphoscintigraphy in sentinel node detection is about 100%. The sentinel lymph node should be processed for intraoperative frozen section examination in its entirety, based on conventional histopathology and, when necessary, immune staining with anti-cytokeratin antibody. Nowadays, lymphoscintigraphy is a useful procedure in patients with different clinical evidence of breast cancer. (orig.)

    The incidence of supraclavicular metastasis as the initial failure and the failure patterns in patients with four or more positive axillary lymph nodes (PALNs) after breast-conserving therapy (BCT) without prophylactic supraclavicular irradiation were investigated. Between 1991 and 2002, a total of 48 women with four or more PALNs underwent BCT without prophylactic supraclavicular irradiation (33 patients with 4-9 PALNs; 15 patients with ≥10 PALNs). The median follow-up time was 50 months. Among the patients with 4-9 PALNs, 3% had isolated supraclavicular metastasis as the initial failure, and 30% had distant metastasis as the initial failure. Among patients with ≥10 PALNs, 7% had isolated supraclavicular metastasis as the initial failure, and 40% had distant metastasis as the initial failure. The 4-year isolated supraclavicular failure rates were 5% for all patients, 3% for patients with 4-9 PALNs, and 8% for patients with ≥10 PALNs. In patients who had undergone BCT and had had four or more PALNs, the major failure pattern was distant failure with or without locoregional failure; isolated supraclavicular failure as the initial failure comprised a less common failure pattern. Omission of prophylactic supraclavicular irradiation may be acceptable for this subset of patients. (author)

  16. Fine-needle aspirates CYFRA 21-1 is a useful tumor marker for detecting axillary lymph node metastasis in breast cancer patients.

    Jung Hyun Yoon

    Full Text Available INTRODUCTION: To assess whether the value of CYFRA21-1 in the aspirates of ultrasonography-guided fine-needle aspiration biopsy (US-FNAB can contribute to improving the performances of US-FNAB in the diagnosis of axillary lymph node (LN metastasis in breast cancer patients. METHODS: US-FNAB was performed in 156 axillary LNs in 152 breast cancer patients (mean age: 51.4 years, range: 17-92 years. Concentrations of CYFRA21-1 were measured from washouts of the syringe used during US-FNAB. Tumor marker concentrations, US-FNAB, intraoperative sentinel node biopsy (SNB, and surgical pathology results were reviewed and analyzed. For comparison, the values of CEA and CA15-3 were also measured from washouts. RESULTS: Among the 156 LNs, 75 (48.1% were benign, and 81 (51.9% were metastases. Mean concentrations of CYFRA21-1 were significantly higher in metastasis compared to benign LNs (P<0.001. US-FNAB combined to CYFRA21-1 showed significantly higher sensitivity, NPV, and accuracy compared to US-FNAB alone (all values P<0.05. All diagnostic indices of US-FNAB combined to CYFRA21-1 were significantly higher compared to US-FNAB combined with CEA or CA15-3 (all P<0.001. Of the 28 metastatic LNs which showed metastasis on SNB, CYFRA21-1 showed higher positive rate of 75.0% (CEA or CA15-3∶60.7%, P = 0.076. CONCLUSION: Measuring CYFRA 21-1 concentrations from US-FNAB aspirates improves sensitivity, NPV, and accuracy of US-FNAB alone, and may contribute to reducing up to 75.0% of unnecessary intraoperative SNB. Compared to CEA or CA15-3, CYFRA21-1 shows significantly higher performances when combined to US-FNAB in the preoperative diagnosis of LN metastasis in breast cancer patients.

    To evaluate the diagnostic performance of breast magnetic resonance imaging (MRI) in preoperative evaluation of axillary lymph node metastasis (ALNM) in breast cancer patients and to assess whether breast MRI can be used to exclude advanced nodal disease. A total of 425 patients were included in this study and breast MRI findings were retrospectively reviewed. The diagnostic performance of breast MRI for diagnosis of ALNM was evaluated in all patients, patients with neoadjuvant chemotherapy (NAC), and those without NAC (no-NAC). We evaluated whether negative MRI findings (cN0) can exclude advanced nodal disease (pN2-pN3) using the negative predictive value (NPV) in each group. The sensitivity and NPV of breast MRI in evaluation of ALNM was 51.3 % (60/117) and 83.3 % (284/341), respectively. For cN0 cases on MRI, pN2-pN3 manifested in 1.8 % (6/341) of the overall patients, 0.4 % (1/257) of the no-NAC group, and 6 % (5/84) of the NAC group. The NPV of negative MRI findings for exclusion of pN2-pN3 was higher for the no-NAC group than for the NAC group (99.6 % vs. 94.0 %, p = 0.039). Negative MRI findings (cN0) can exclude the presence of advanced nodal disease with an NPV of 99.6 % in the no-NAC group. (orig.)

    A 49 year-old woman diagnosed with infiltrating lobular breast carcinoma, underwent a right mastectomy and sentinel node biopsy (SLNB). The resected sentinel lymph nodes were negative for malignancy, with an axillary lymphadenectomy not being performed. In the early post-operative period, the patient reported an axillary skin tension sensation, associated with a painful palpable cord. These are typical manifestations of axillary web syndrome (AWS), a poorly known axillary surgery complication, from both invasive and conservative interventions. By presenting this case we want to focus the attention on a pathological condition, for which its incidence may be underestimated by not including it in SLNB studies. It is important for nuclear medicine physicians to be aware of AWS as a more common complication than infection, seroma, or lymphoedema, and to discuss this possible event with the patient who is consenting to the procedure.

    To determine the utility of {sup 18}F-FDG (FDG) PET/CT performed in an early and delayed phase during neoadjuvant chemotherapy in the prediction of lymph node histopathological response in patients with locally advanced breast cancer. FDG PET/CT studies performed in 76 patients (mean age 53 years) at baseline (PET-1), after the second course of chemotherapy (PET-2) and after the last course of chemotherapy (PET-3) were prospectively analysed. Inclusion criteria were lymph node involvement detected by PET/CT and non-sentinel node biopsy before or after the baseline PET/CT scan. Following the recommendations of the 12th International Breast Conference (St. Gallen), the patients were divided into five subgroups in relation to biological prognostic factors by immunohistochemistry. For diagnosis visual and semiquantitative analyses was performed. Absence of detectable lymph node uptake on the PET-2 or PET-3 scan with respect to the PET-1 scan was considered metabolic complete response (mCR). Lymph nodes were histopathologically classified according the lymph node regression grade and in response groups as pathological complete response (pCR) or not pCR (type A/D or B/C of the Smith grading system, respectively). ROC analysis was performed to determine a cut-off value of Δ% SUV1-2 and SUV1-3 for prediction of nodal status after chemotherapy. An association between mCR and pCR was found (Cohen's kappa analysis), and associations between phenotypes and metabolic behaviour and the final histopathological status were also found. Lymph node pCR was seen in 34 patients. The sensitivity, specificity, and positive and negative predictive values of PET-2 and PET-3 in establishing the final status of the axilla after chemotherapy were 52 %, 45 %, 50 % and 47 %, and 33 %, 84 %, 67 % and 56 %, respectively. No significant relationship was observed between mCR on PET-2 and PET-3 and pCR (p = 0.31 and 0.99, respectively). Lymph node metabolism on PET-1 was not able to predict

    To determine the utility of 18 F-FDG (FDG) PET/CT performed in an early and delayed phase during neoadjuvant chemotherapy in the prediction of lymph node histopathological response in patients with locally advanced breast cancer. FDG PET/CT studies performed in 76 patients (mean age 53 years) at baseline (PET-1), after the second course of chemotherapy (PET-2) and after the last course of chemotherapy (PET-3) were prospectively analysed. Inclusion criteria were lymph node involvement detected by PET/CT and non-sentinel node biopsy before or after the baseline PET/CT scan. Following the recommendations of the 12th International Breast Conference (St. Gallen), the patients were divided into five subgroups in relation to biological prognostic factors by immunohistochemistry. For diagnosis visual and semiquantitative analyses was performed. Absence of detectable lymph node uptake on the PET-2 or PET-3 scan with respect to the PET-1 scan was considered metabolic complete response (mCR). Lymph nodes were histopathologically classified according the lymph node regression grade and in response groups as pathological complete response (pCR) or not pCR (type A/D or B/C of the Smith grading system, respectively). ROC analysis was performed to determine a cut-off value of Δ% SUV1-2 and SUV1-3 for prediction of nodal status after chemotherapy. An association between mCR and pCR was found (Cohen's kappa analysis), and associations between phenotypes and metabolic behaviour and the final histopathological status were also found.

    Full Text Available Metastasization and distinction from mammary carcinoma is of great clinical importance because of different treatment modalities. Here, we discuss a case of stage IIIC ovarian serous carcinoma, presenting with bilateral axillary nodes metastasis after 25 months interval of its initial presentation. Increased serum CA-125 level caused clinical suspicion. Computed tomography scan of abdomen and pelvis showed no residual disease or any abdominal lymphadenopathy. Mammography of both breast were normal. Bilateral axillary nodes were noted. Guided fine needle aspiration cytology (FNAC and biopsy of ovarian carcinoma to axillary node is a rare event. Its recogn done. Cytomorphology revealed poorly differentiated carcinoma, compatible to that of primary ovarian tumor. Thus, metastatic carcinoma to axillary node from ovary was confirmed. This case illustrates a rare metastatic presentation of ovarian carcinoma and unequivocal role of FNAC to provide rapid diagnosis and preferred to be first line diagnostic procedure.

    Full Text Available Trough computed tomography (CT, it is possible to evaluate lymph nodes in detail and to detect changes in these structures earlier than with radiographs and ultrasound. Lack of information in the veterinary literature directed the focus of this report to normal aspects of the axillary and mediastinal lymph nodes of adult dogs on CT imaging. A CT scan of 15 normal adult male and female Rottweilers was done. To define them as clinically sound, anamnesis, physical examination, complete blood count, renal and hepatic biochemistry, ECG, and thoracic radiographs were performed. After the intravenous injection of hydrosoluble ionic iodine contrast medium contiguous 10mm in thickness thoracic transverse images were obtained with an axial scanner. In the obtained images mediastinal and axillary lymph nodes were sought and when found measured in their smallest diameter and their attenuation was compared to musculature. Mean and standard deviation of: age, weight, body length and the smallest diameter of the axillary and mediastinal lymph nodes were determined. Mean and standard deviation of parameters: age 3.87±2.03 years, weight 41.13±5.12, and body length 89.61±2.63cm. Axillary lymph nodes were seen in 60% of the animals, mean of the smallest diameter was 3.58mm with a standard deviation of 2.02 and a minimum value of 1mm and a maximum value of 7mm. From 13 observed lymph nodes 61.53% were hypopodense when compared with musculature, and 30.77% were isodense. Mediastinal lymph nodes were identified in 73.33% of the dogs; mean measure of the smallest diameter was 4.71mm with a standard deviation of 2.61mm and a minimum value of 1mm, and a maximum value of 8mm. From 14 observed lymph nodes 85.71% were isodense when compared with musculature and 14.28% were hypodense. The results show that it is possible to visualize axillary and mediastinal lymph nodes in adult clinically sound Rottweilers with CT using a slice thickness and interval of 10mm. The

    Purpose: This prospective study was conducted to determine predictors of epidermal thickening during and after whole-breast radiation therapy (XRT) using objective measurements acquired with ultrasound. Methods and Materials: After breast-conserving surgery, 70 women received a definitive course of whole-breast XRT (50 Gy plus boost). Prior to XRT, at week 6 of XRT, and 6 weeks after XRT, patients underwent objective ultrasound measurements of epidermal thickness over the lumpectomy cavity and all 4 quadrants of the treated breast. A skin thickness ratio (STRA) was then generated normalizing for corresponding measurements taken of the untreated breast. Results: Baseline measurements indicated that 87% of patients had skin thickening in the treated versus untreated breast (mean increase, 27%; SD, 0.29) prior to XRT. The STRA increased significantly by week 6 of XRT (mean, 25%; SD, 0.46) and continued to increase significantly 6 weeks after XRT (mean, 33%; SD, 0.46) above baseline measurements (P<.001 for both time points). On multivariate analysis, breast volume (P=.003) and surgical evaluation of the axilla with full lymph node dissection (P<.05) predicted for more severe changes in the STRA 6 weeks after XRT compared with baseline. STRA measurements correlated with physician ratings of skin toxicity according to Radiation Therapy Oncology Group grading criteria. Conclusions: This is one of the first studies to objectively document that lymph node surgery affects XRT-induced skin thickening in patients with breast cancer. Surgical evaluation of the axilla with complete lymph node dissection was associated with the most severe XRT-induced skin changes after XRT completion. These results may inform future studies aimed at minimizing side effects of XRT and surgery, particularly when surgical lymph node assessments may not alter breast cancer management or outcome.

    marked on the skin with indelible ink and a permanent point tattoo of carbon black ink. The depth of the sentinel node from the skin mark is measured in an orthogonal view with a radioactive marker placed on the skin mark. At surgery blue dye is used as a mapping technique and the sentinel nodes are also checked by using a gamma probe to confirm the true sentinel nodes and that the sentinel nodes have been removed. Several lymphoscintigraphic techniques have been described where the tracer is injected peritumorally, intratumorally or intradermally. We favour the peritumour injection technique under ultrasound control. The lymphatic drainage in breast carcinoma is predominantly to axillary lymph nodes but also to internal mammary lymph nodes (IM) and occasionally to intramammary, infraclavicular and supraclavicular node fields. To most accurately define the lymph drainage all sentinel nodes should be found. In our experience the axillary sentinel nodes were accurately staged in 96% of patients. The sentinel nodes are removed at surgery and sent for pathology. As there are a limited number usually 1-3 sentinel nodes this allows for more specific histopathology and immunohistochemistry. Focused histopathology allows more specific and accurate detection of micrometastases. SLNB has also been used in vulval, penile, head and neck, thyroid, oropharyngeal cancers and also intraoperatively in colon cancer. The techniques require a sophisticated integration of a multidisciplinary team with significant learning curves for the surgeons, nuclear medicine physicians, technologists and pathologists. There has to be good communication between all groups with precise imaging and surgical techniques. With lymphoscintigraphy there are many techniques described and the literature reports excellent results in major centres. With lymphoscintigraphy in Australia we use small particle colloids (Tc99m antimony sulphide colloid) which allows excellent definition of lymph channels and more

    Background: For patients with Stage II breast cancer with one to three positive lymph nodes, controversy exists about whether radiation as a component of treatment provides a survival benefit. Methods and Materials: We analyzed data from patients with Stage II breast cancer with one to three positive lymph nodes diagnosed from 1988-2002 in the Surveillance, Epidemiology, and End Results registry and compared the outcome of 12,693 patients treated with breast-conservation therapy with radiation (BCT + XRT) with the 18,902 patients treated with mastectomy without radiation (MRM w/o XRT). Results: Patients treated with BCT + XRT were younger, were more likely to be treated in recent years of the study period, more commonly had T1 primary tumors, and had fewer involved nodes compared with those treated with MRM w/o XRT (p < 0.001 for all differences). The 15-year breast cancer-specific survival rate for the BCT + XRT group was 80% vs. 72% for the MRM w/o XRT group (p < 0.001). Cox regression analysis showed that MRM w/o XRT was associated with a hazard ratio for breast cancer death of 1.19 (p < 0.001) and for overall death of 1.25 (p < 0.001). The survival benefit in the BCT + XRT group was not limited to subgroups with high-risk disease features. Conclusions: Radiation use was independently associated with improved survival for patients with Stage II breast cancer with one to three positive lymph nodes. Because multivariate analyses of retrospective data cannot account for all potential biases, these data require confirmation in randomized clinical trials

    Objectives: To prospectively evaluate the accuracy of real-time ultrasound combined with supine-MRI using volume navigation technique (RtMR-US) in diagnosis and biopsy of incidental breast lesions (ILSM) and axillary lymph nodes (LNSM) suspicious of malignancy on contrast enhanced magnetic resonance imaging (CE-MRI). Materials and methods: Five hundred and seventy-seven women were examined using breast CE-MRI. Those with incidental breast lesions not identified after second-look ultrasound (US) were recruited for RtMR-US. Biopsy was performed in ILSM. Breast lesions were categorized with BI-RADS system and Fisher’ exact test. Axillary lymph nodes morphology was described. To assess efficacy of RtMR-US, diagnostic accuracy, sensitivity, specificity, detection rate and Kappa index of conventional-US and RtMR-US were calculated. Results: Forty-three lesions were detected on CE-MRI before navigation. Eighteen were carcinomas and 25 ILSM. Of these, 21 underwent a RtMR-US. Detection rate on RtMR-US (90.7%) was higher than on conventional-US (43%) (p < 0.001). Agreement between both techniques was low (k = 0.138). Twenty ILSM and 2 LNSM were biopsied. Sixty-five percent were benign (100% of BI-RADS3 and 56% of BI-RADS4-5). Diagnostic performance of RtMR-US identifying malignant nodules for overall lesions and for the subgroup of ILSM was respectively: sensitivity 96.3% and 100%, specificity 18.8% and 30.7%, positive predictive value 66.7% and 43.7%, negative predictive value 75% and 100%. In addition RtMR-US enabled biopsy of 2 metastatic lymph nodes. Conclusions: Real time-US with supine-MRI using a volume navigation technique increases the detection of ILSM. RtMR-US may be used to detect occult breast carcinomas and to assess cancer extension, preventing unnecessary MRI-guided biopsies and sentinel lymph node biopsies. Incidental lesions BI-RADS 3 non-detected on conventional-US are probably benign.

    Today, sentinel lymph node dissection (SLND) has replaced axillary lymph node dissection (ALND) as standard procedure for staging of the axilla in the treatment of breast cancer. SLND can accurately stage the axilla by removing on average only two lymph nodes. Only in case of metastatic spread...... to sentinel nodes an ALND is offered. Removing fewer nodes has made more extensive histopathological examinations of the lymph nodes possible and as a consequence more metastases are found. This has resulted in stage migration. Based on data from the nationwide Danish Breast Cancer Cooperative Group (DBCG......) database we have estimated the magnitude and therapeutic consequences of this stage migration in Denmark by comparing the distribution of lymph node metastases in breast cancer patients operated in 1993-1996 and 2005-2008; before and after introducing SLND. The proportion of patients having macrometastases...

OSNA results showed CK19 expression in 80% of primary cases, so if used for diagnosis of lymph node metastasis would lead to a false-negative result...... in 20% of patients with cervical lymph node metastases. CONCLUSIONS: OSNA in its current form is not suitable for use in OSCC SLNB due to inadequate expression of the CK19 target in all case.

    The sentinel lymph node is defined as the first draining node from a primary tumor and reflects the histologic feature of the remainder of the lymphatic basin status. The aim of this study was to evaluate the usefulness of lymphoscintigraphy and intraoperative radioguided gamma probe for identification and removal of sentinel lymph node in breast cancer. Lymphoscintigraphy was performed preoperatively in 15 patients with biopsy proven primary breast cancer. Tc-99m antimony sulfide colloid was injected intradermally at four points around the tumor. Imaging acquisition included dynamic imaging, followed by early and late static images at 2 hours. The sentinel lymph node criteria on lymphoscintigraphy is the first node of the highest uptake in early and late static images. We tagged the node emitting the highest activity both n vivo an ex vivo. Histologic study for sentinel and axillary lymph node investigation was done by Hematoxylin-Eosin staining. On lymphoscintigraphy, three of 15 patients had clear lymphatic vessels in dynamic images, and 11 of 15 patients showed sentinel lymph node in early static image and three in late static 2 hours image. Mean detection time of sentinel lymph node on lynphoscintigraphy was 33.5{+-}48.4 minutes. The sentinel lymph node localization and removal by lymphoscintigraphy and intraoperative gamma probe were successful in 14 of 15 patients (detection rate: 93.3%). On lymphoscintigraphy, 14 of 15 patients showed 2.47{+-}2.00 sentinel lymph nodes. On intraoperative gamma probe, 2.36{+-}1.96 sentinel lymph nodes were detected. In 7 patients with positive results of sentinel lymph node metastasis, 5 patients showed positive results of axillary lymph node (sensitivity: 72%) but two did not . In 7 patients with negative results of sentinel lymph node metastasis, all axillary nodes were free of disease (specificity: 100%). Sentinel lymph node biopsy with lymphoscintigraphy and intraoperative gamma probe is a reliable method to predict

    Background: Breast cancer in Egypt is the most common cancer among women and is the leading cause of cancer mortality. Traditionally, axillary lymph node involvement is considered among the most important prognostic factors in breast cancer. Nonetheless, accumulating evidence suggests that axillary lymph node ratio should be considered as an alternative to classical pN classification. Materials and methods: We performed a retrospective analysis of patients with operable node positive breast cancer, to investigate the prognostic significance of axillary lymph node ratio. Results: Five-hundred patients were considered eligible for the analysis. Median follow-up was 35 months (95% Cl 32-37 months), the median disease-free survival (DFS) was 49 months (95% Cl, 46.4-52.2 months). The classification of patients based on pN staging system failed to prognosticate DFS in the multivariate analysis. Conversely, grade 3 tumors, and the intermediate (> 0.20 to <0.65) and high (>0.65) LNR were the only variables that were independently associated with adverse DFS. The overall survival (OS) in this series was 69 months (95% Cl 60-77). Conclusion: The analysis of outcome of patients with early breast cancer in Egypt identified the adverse prognostic effects of high tumor grade, ER negativity and intermediate and high LNR on DFS. If the utility of the LNR is validated in other studies, it may replace the use of absolute number of axillary lymph nodes.

    Murine lymph nodes are intensively studied but often assigned incorrectly in scientific papers. In BALB/cAnNCrl mice, we characterized a total of 22 different lymph nodes. Peripheral nodes were situated in the head and neck region (mandibular, accessory mandibular, superficial parotid, cranial deep cervical nodes), and at the forelimb (proper axillary, accessory axillary nodes) and hindlimb (subiliac, sciatic, popliteal nodes). Intrathoracic lymph nodes included the cranial mediastinal, tracheobronchal and caudal mediastinal nodes. Abdominal lymph nodes were associated with the gastrointestinal tract (gastric, pancreaticoduodenal, jejunal, colic, caudal mesenteric nodes) or were located along the major intra-abdominal blood vessels (renal, lumbar aortic, lateral iliac, medial iliac and external iliac nodes). Comparative and nomenclative aspects of murine lymph nodes are discussed. The position of the lymph nodes of BALB/cAnNCrl mice is summarized and illustrated in an anatomical chart containing proposals for both an official nomenclature according to the Nomina Anatomica Veterinaria and English terms.

    The aim of this study was to compare the diagnostic performance of [(18)F]fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) with that of sonography and sonographically guided fine-needle aspiration (FNA) for determining the preoperative axillary lymph node (ALN) status and to evaluate the factors related to false-negative PET-CT, sonographic, and FNA results in ALN staging of invasive ductal carcinoma. From March 2009 to July 2012, 226 patients had a diagnosis of primary breast cancer. Among these patients, 107 constituted the study population after exclusion of transferred patients and patients with breast cancer other than invasive ductal carcinoma. The diagnostic performance of the modalities was compared with pathologic reports. Univariate and multivariate analyses were used to evaluate the relationship between clinicopathologic factors (symptoms, T stage, hormone receptors, and histologic grade), false-negative results, and true-negative results on PET-CT, sonography, and FNA. Of the 107 patients, 45 (42.1%) had positive results on final pathologic analysis of ALNs. Sonographically guided FNA had a significantly higher specificity, positive predictive value, accuracy, and area under the receiver operating characteristic curve than sonography and PET-CT (P < .01). When sonography and PET-CT were combined, the sensitivity was significantly improved (P = .019) compared with sonography alone. When FNA and PET-CT were combined, the sensitivity and negative predictive value were significantly increased compared with each modality (P < .01). Sonographically guided FNA was found to be an excellent diagnostic tool for preoperative evaluation of the ALN status. To obviate the step of sentinel lymph node biopsy for determining the ALN status, combined evaluation of ALNs by these modalities may be more complementary than the use of a single modality. © 2014 by the American Institute of Ultrasound in Medicine.

    Axillary lymph node (ALN) status is an important prognostic factor for breast cancer patients. With increasing numbers of patients undergoing neoadjuvant chemotherapy (NAC), issues concerning sentinel lymph node biopsy (SLNB) after NAC have emerged. We analyzed the clinicopathologic features and developed a nomogram to predict the possibility of nonsentinel lymph node (NSLN) metastases in patients with positive SLNs after NAC. A retrospective medical record review was performed of 140 patients who had had clinically positive ALNs at presentation, had a positive SLN after NAC on subsequent SLNB, and undergone axillary lymph node dissection (ALND) from 2008 to 2014. On multivariate stepwise logistic regression analysis, pathologic T stage, lymphovascular invasion, SLN metastasis size, and number of positive SLN metastases were independent predictors for NSLN metastases (P Samsung Medical Center NAC nomogram was developed to predict the likelihood of additional positive NSLNs. The Samsung Medical Center NAC nomogram could provide information to surgeons regarding whether to perform additional ALND when the permanent biopsy revealed positive findings, although the intraoperative SLNB findings were negative.

    Objective: To study the CT perfusion features of various lymph nodes in the neck. Methods: Dynamic perfusion CT scanning was performed in 83 neck lymph nodes proved by pathology, including tuberculosis lymph nodes, lymphoma and metastatic lymph nodes. The shapes, blood flow modes, and perfusion parameters of these lymph nodes were compared among 3 groups. Statistical analysis of L/T and CT perfusion parameters was performed by one-way ANOVA and LSD test. Results: The values of MTT of tuberculosis lymph nodes, lymphoma and metastatic lymph nodes were (28.13±5.08), (31.08±5.82), and (11.24±5.31) s, respectively. The MTT of metastatic lymph nodes was statistically lower than that of tuberculosis lymph nodes and lymphoma (P -1 · 100 g -1 , respectively. The values of BV were (24.68±2.84), (25.30±3.16), and (25.15± 8.81) ml·100 g -1 respectively. The values of TTP were (40.90±8.85), (40.67±6.45), and (40.98±6.62) s, respectively. There were no significant differences in L/T, BF, BV and TTP among tuberculosis lymph nodes, lymphoma and metastatic lymph nodes (P>0.05). Conclusion: CT perfusion, especially combination functional imaging with perfusion images may be helpful in judging the nature of neck lymph nodes. (authors)

    Full Text Available The tumour microenvironment consists of malignant cells, stroma, and immune cells. The role of adaptive immunity in inducing a pathological complete response (pCR in breast cancer with neoadjuvant chemotherapy (NAC is well studied. The contribution of innate immunity, however, is poorly documented. Breast tumours and axillary lymph nodes (ALNs from 33 women with large and locally advanced breast cancers (LLABCs undergoing NAC were immunohistochemically assessed for tumour-infiltrating macrophages (TIMs: M1 and M2, neutrophils (TINs, and dendritic cells (TIDCs using labelled antibodies and semiquantitative methods. Patients’ blood neutrophils (n=108, DCs (mDC1 and pDC, and their costimulatory molecules (n=30 were also studied. Pathological results were classified as pCR, good (GPR or poor (PRR. In breast and metastatic ALNs, high levels of CD163+ TIMs were significantly associated with a pCR. In blood, high levels of neutrophils were significantly associated with pCR in metastatic ALNs, whilst the % of mDC1 and pDC and expression of HLA-DR, mDC1 CD40, and CD83 were significantly reduced. NAC significantly reduced tumour DCs but increased blood DCs. PPRs to NAC had significantly reduced HLA-DR, CD40, and CD86 expression. Our study demonstrated novel findings documenting the differential but important contributions of innate immunity to pCRs in patients with LLABCs undergoing NAC.

    Sentinel lymph node (SLN) biopsy is the standard of care for axillary staging in breast cancer, but many clinical scenarios questioning the validity of SLN biopsy remain. Here we describe our experience with reoperative-SLN (re-SLN) biopsy after previous mastectomy. Review of the SLN database from September 1996 to December 2007 yielded 20 procedures done in the setting of previous mastectomy. SLN biopsy was performed using radioisotope with or without blue dye injection superior to the mastectomy incision, in the skin flap in all patients. In 17 of 20 patients (85%), re-SLN biopsy was performed for local or regional recurrence after mastectomy. Re-SLN biopsy was successful in 13 of 20 patients (65%) after previous mastectomy. Of the 13 patients, 2 had positive re-SLN, and completion axillary dissection was performed, with 1 having additional positive nodes. In the 11 patients with negative re-SLN, 2 patients underwent completion axillary dissection demonstrating additional negative nodes. One patient with a negative re-SLN experienced chest wall recurrence combined with axillary recurrence 11 months after re-SLN biopsy. All others remained free of local or axillary recurrence. Re-SLN biopsy was unsuccessful in 7 of 20 patients (35%). In three of seven patients, axillary dissection was performed, yielding positive nodes in two of the three. The remaining four of seven patients all had previous modified radical mastectomy, so underwent no additional axillary surgery. In this small series, re-SLN was successful after previous mastectomy, and this procedure may play some role when axillary staging is warranted after mastectomy.

    Sentinel lymph node (SLN) biopsy has increasingly become important in axillary staging of breast cancer patients since SLN biopsy alleviates the postoperative complications of previously practiced axillary lymph node dissections. Nevertheless, the procedures of SLN biopsy using blue dye and radioactive substance are still intraoperative, and the latter methods are also ionizing. In this pilot study, we have proposed noninvasive in vivo spectroscopic photoacoustic (PA) SLN mapping using gold nanorods as lymph node tracers in a rat model. Gold nanorods have biocompatibility, high optical absorption, and easily tuned surface plasmon resonance peak wavelength.

    To evaluate the reproducibility of the sentinel lymph node (SLN) technique in male breast cancer. We retrospectively analysed 21 male patients diagnosed with breast cancer in our hospital from 2008 to 2016 with, at least, 18 months follow-up. Fifteen patients underwent selective sentinel lymph node biopsy (SLNB) following the usual protocols with peritumoral injection of 18.5-111MBq of 99m Tc-nanocoloides and acquisition of planar images 2hours after the injection. In 2 cases it was necessary to perform a SPECT/CT to locate the SLN. Immunohistochemistry and molecular techniques (OSNA) were used for their analysis. Six patients did not undergo SLNB because they had pathological nodes or distant disease at the time of diagnosis. SLNB was performed in 15 patients. The SLN was negative in 6 patients and positive in the remaining 9. Three patients with positive SLNB did not need axillary lymphadenectomy because of the low number of copies by molecular analysis OSNA. Axillary lymphadenectomy was performed in the remaining 6 patients with the result of 4 positive axillary lymphadenectomies and 2 that did not show further extension of the disease. According to our experience, SLNB in males is a reproducible, useful, safe and reliable technique which avoids unnecessary axillary lymphadenectomy and prevents the appearance of undesirable effects.

    To observe and document the clinical features, mode of presentation, histopathological and immunohistochemical features of Kikuchi's disease. An observational and descriptive study. Histopathology department, Armed Forces Institute of Pathology, Rawalpindi from January, 1997 to December, 2001. SUBJECTS AND METHODS Thirty-one cases of Kikuchi's disease of lymph node were diagnosed during the study period. Hematoxylin and Eosin stained slides were examined and histological features including extent of architectural effacement, zonation, extent of necrosis, and cellular composition were recorded. Special stains and immunohistochemistry was done. Kikuchi's disease was diagnosed in 31 cases (1.9%) out of 5762 lymph node biopsies received. There were 10 male and 21 female patients. Ten patients were aged between 21 and 25 years (33%). Eight (25.8%) patients were from pediatric age group. Thirty patients (96.4%) presented with cervical lymphadenopathy. Thirteen (41.9%) lymph nodes showed fragmentation, while 8 (25.8%) revealed perinodal spill. Seventeen cases (54.7%) showed more than 50% necrosis. Zonation was seen in 13 (41.9%) cases. Immunohistochemistry showed majority of cells to be histiocytes and T-lymphocytes. Eight cases were followed-up, all of which showed regression of symptoms over 4-8 months. Kikuchi's disease is an uncommon cause of cervical lymphadenopathy in young females. Necrotic areas, karyorrhexis, zonation, absence of neutrophils and predominance of histiocytes with many plasmacytoid monocytes are features that aid in diagnosis. Immunohistochemistry can be used to differentiate it from malignant lymphoma. It is important for clinicians and pathologists to be aware of this entity as it is a benign disorder with a self-limiting course.

    Full Text Available Active-targeted delivery to lymph nodes represents a major advance toward more effective treatment of immune-mediated disease. The MECA79 antibody recognizes peripheral node addressin molecules expressed by high endothelial venules of lymph nodes. By mimicking lymphocyte trafficking to the lymph nodes, we have engineered MECA79-coated microparticles containing an immunosuppressive medication, tacrolimus. Following intravenous administration, MECA79-bearing particles showed marked accumulation in the draining lymph nodes of transplanted animals. Using an allograft heart transplant model, we show that targeted lymph node delivery of microparticles containing tacrolimus can prolong heart allograft survival with negligible changes in tacrolimus serum level. Using MECA79 conjugation, we have demonstrated targeted delivery of tacrolimus to the lymph nodes following systemic administration, with the capacity for immune modulation in vivo.

    Purpose: To aim of this study was to evaluate the diagnostic accuracy of axillary lymph node sonography, if necessary in collaboration with US-guided large core biopsy, in the preoperative evaluation of breast cancer patients scheduled for quadrantectomy and sentinel lymph node excision. Materials and methods: From July 2001 to December 2002, we evaluated 117 breast cancer patients with ultrasound and, where indicated, FNAB. Breast lesions has diameters between 4 and 26 mm (mean diameter 11 mm). Fifteen (13%) of the 117 patients were excluded from the series as they did not found fulfil the criteria for preliminary sonography of the axilla: in 9 patients fewer than 4 nodes were detected and in 6 patients the breast lesions were intraoperatively found to be benign. Eleven patients (10.7%) with sonographically suspicious axillary nodes were sampled by US-guided core biopsy using a 14 or 16 Gauge Tru-Cut needle. Results: The ultrasound study aims to evaluate the dimensions and morphology of the breast lesion as well as detect and assess at least 4 axillary nodes. These were evaluated for hilar and cortical thickening and radio between the sinus diameter and the total longitudinal diameter. Lymph nodes with hilar diameters equal to or greater than 50% of the longitudinal diameter were considered normal. Of the 102 patients evaluated, 77 (75.7%) had normal axillary nodes according to the US criteria adopted. Negativity was confirmed by histology in 56 cases (72.7%, true negative); 21 (27.3%, false negative) were found to be positive, in contrast with the sonographic appearance. The false negative cases were due to lymph node micrometastasis which probably did not cause morphologic alterations perceptible at ultrasound. The remaining 25 patients (24.5%) had axillary lymph nodes classified as suspicious. In 13 cases of (52%, true positive) there was agreement with histology, whereas in 12 cases (48%, false positive) the US suspicion was not confirmed at surgery. The most

    The purpose of this study was to evaluate the advantages of surgery for diagnosis and treatment of cervical lymph node tuberculosis. This was a retrospective study from 1st January 1998 to 31st December 2007 including 30 patients with cervical lymph node tuberculosis. The population included 60% autochthones with a mean age of 47.1 years and a female predominance (73.33%). The lymph nodes were most often supraclavicular, unilateral, firm, and a mean 3 cm at its largest span. Lymph nodes were excised for diagnosis in 22 patients, which demonstrated specific granulomatous and giant cell lesions with caseous necrosis in 21 patients out of 22. Five abscessed adenopathies required surgical drainage, and three cases required repeated lymph node cleaning after well-conducted medical treatment. Surgery retains an important place in the diagnosis and treatment of cervical lymph node tuberculosis.

    To evaluate the association between tumour FDG uptake on preoperative PET/CT and axillary lymph node metastasis (ALNM) according to breast cancer subtype. The records of 671 patients with invasive breast cancer who underwent {sup 18} F-FDG PET/CT and surgery were reviewed. Using immunohistochemistry, tumours were divided into three subtypes: oestrogen receptor (ER)-positive/human epidermal growth factor receptor 2 (HER2)-negative, HER2-positive, and triple-negative. Tumour FDG uptake, expressed as maximum standardized uptake value (SUV{sub max}), and clinicopathological variables were analysed. ALNM was present in 187 of 461 ER-positive/HER2-negative, 54 of 97 HER2-positive, and 38 of 113 triple-negative tumours. On multivariate analysis, high tumour SUV{sub max} (≥4.25) (P < 0.001), large tumour size (>2 cm) (P = 0.003) and presence of lymphovascular invasion (P < 0.001) were independent variables associated with ALNM. On subset analyses, tumour SUV{sub max} maintained independent significance for predicting ALNM in ER-positive/HER2-negative (adjusted odds ratio: 3.277, P < 0.001) and HER2-positive tumours (adjusted odds ratio: 14.637, P = 0.004). No association was found for triple-negative tumours (P = 0.161). Tumour SUV{sub max} may be an independent prognostic factor for ALNM in patients with invasive breast cancer, especially in ER-positive/HER2-negative and HER2-positive subtypes, but not in those with triple-negative subtype.

    To investigate the feasibility and potential added value of dedicated axillary 18F-FDG hybrid PET/MRI, compared to standard imaging modalities (i.e. ultrasound [US], MRI and PET/CT), for axillary nodal staging in clinically node-positive breast cancer. Twelve patients with clinically node-positive breast cancer underwent axillary US and dedicated axillary hybrid 18F-FDG PET/MRI. Nine of the 12 patients also underwent whole-body PET/CT. Maximum standardized uptake values (SUVmax) were measured for the primary breast tumor and the most FDG-avid axillary lymph node. A positive axillary lymph node on dedicated axillary hybrid PET/MRI was defined as a moderate to very intense FDG-avid lymph node. The diagnostic performance of dedicated axillary hybrid PET/MRI was calculated by comparing quantitative and its qualitative measurements to results of axillary US, MRI and PET/CT. The number of suspicious axillary lymph nodes was subdivided as follows: N0 (0 nodes), N1 (1-3 nodes), N2 (4-9 nodes) and N3 (≥ 10 nodes). According to dedicated axillary hybrid PET/MRI findings, seven patients were diagnosed with N1, four with N2 and one with N3. With regard to mean SUVmax, there was no significant difference in the primary tumor (9.0 [±5.0] vs. 8.6 [±5.7], p = 0.678) or the most FDG-avid axillary lymph node (7.8 [±5.3] vs. 7.7 [±4.3], p = 0.767) between dedicated axillary PET/MRI and PET/CT. Compared to standard imaging modalities, dedicated axillary hybrid PET/MRI resulted in changes in nodal status as follows: 40% compared to US, 75% compared to T2-weighted MRI, 40% compared to contrast-enhanced MRI, and 22% compared to PET/CT. Adding dedicated axillary 18F-FDG hybrid PET/MRI to diagnostic work-up may improve the diagnostic performance of axillary nodal staging in clinically node-positive breast cancer patients. (orig.)

    Differentiated thyroid cancer is usually associated with an excellent prognosis and indolent course. Distant metastases are rare events at the onset of thyroid cancer. Among these presentations, metastasis to the axillary lymph nodes is even more unusual: only few cases were previously reported in the literature; there has been no report of axillary lymph node metastasis from follicular thyroid carcinoma. Axillary lymph node metastasis generally arises in the context of disseminated disease and carries an ominous prognosis. Here we present a case of axillary lymph node metastasis in the context of disseminated differentiated thyroid cancer. The patient underwent near total thyroidectomy and neck and axillary lymph node dissection. A histopathological diagnosis of poorly differentiated follicular carcinoma with 'signet ring cells' and Hürthle cell features was established. The patient received radioactive iodine therapy and TSH suppression therapy. Subsequently his serum thyroglobulin level decreased to 44.000 ng/ml from over 100.000 ng/ml. Currently there are only few reported cases of axillary node metastases from thyroid cancer, and to our knowledge, this is the first report on axillary lymph node metastasis from follicular thyroid carcinoma. 'Signet ring cell' is a morphologic feature shared by both benign and, more rarely, malignant follicular thyroid neoplasm, and it generally correlates with an arrest in folliculogenesis. Our case is one of the rare 'signet ring cells' carcinomas so far described

    Axillary lymph node status is an independent prognostic indicator in breast cancer. Intraoperative identification of metastatic carcinoma in sentinel lymph nodes may allow for concurrent axillary lymph node dissection at the time of primary tumor excision. A retrospective review of patients undergoing primary breast cancer excision with sentinel lymph node sampling was performed. Sensitivity and specificity of imprint cytology (touch prep) with and without the incorporation of gross evaluation was determined using permanent section results as the gold standard. Five hundred sixteen lymph nodes were analyzed by imprint cytology in 213 patients, and 203 lymph nodes were analyzed in 74 patients incorporating gross examination. Sensitivity and specificity for the detection of macrometastases by touch prep alone were 60% and 99% respectively with 4 patients undergoing same-day axillary dissection for only micrometastatic disease. False negative causes included lack of transfer of malignant cells in 8 cases and misinterpretation of tumor cells in 6 cases. Incorporating gross examination in the modified protocol resulted in reduced sensitivity of 38%, but achieved the desired 100% specificity and positive predictive value. Imprint cytology alone did not reliably distinguish between micro- and macrometastatic disease. Gross assessment combined with imprint cytology allows for improved assessment of volume of axillary disease, but is an insensitive technique. Copyright © 2017 Elsevier Inc. All rights reserved.

    Lymphatic mapping with selective lymphadenectomy is an attractive approach in breast-cancer patients. It uses existing technology to exploit logical anatomic and physiological principles to identify occult regional lymph-node metastases. The lymphatic flow is visualized and the first (sentinel) lymph node on a direct drainage pathway from the primary tumour is identified. This is the node at greatest risk of harbouring metastatic deposits. Retrieving this node requires a concerted effort from the nuclear medicine physician, surgeon and pathologist. Lymphoscintigraphy can indicate the number of sentinel nodes and their location. The surgeon can use two techniques to find the node. A vital dye injected at the tumour site will stain the lymphatic duct as well as the sentinel node and allow their visual identification. Alternatively, a lymph-node-seeking radiopharmaceutical will also migrate from the tumour site to the sentinel node and will enable its retrieval with the use of a gamma detection probe. The pathologist has a number of techniques to identify tumour deposits in the lymph node. A review of the literature shows that the sentinel node can be found in more than 90% of the patients. With experience, the false-negative rate can be kept down to about 5%. This novel approach of lymphatic mapping with selective lymphadenectomy may lead to a substantial reduction in the need for axillary node dissection in patients with breast cancer without compromising survival and regional control, and without loss of prognostic and staging information. This development will translate into a great reduction in patient morbidity and medical expenses.

    Full Text Available Sentinel lymph nodes are the first lymph nodes in the region that receive lymphatic drainage from a primary tumor. The detection or exclusion of sentinel lymph node micrometastases is critical in the staging of cancer, especially breast cancer and melanoma because it directly affects patient’s prognosis and surgical management. Currently, intraoperative sentinel lymph node biopsies using blue dye and radioisotopes are the method of choice for the detection of sentinel lymph node with high identification rate. In contrast, conventional ultrasound is not capable of detecting sentinel lymph nodes in most cases. Contrast enhanced ultrasound with contrast specific imaging modes has been used for the evaluation and diagnostic work-up of peripherally located suspected lymphadenopathy. The method allows for real-time analysis of all vascular phases and the visualization of intranodal focal “avascular” areas that represent necrosis or deposits of neoplastic cells. In recent years, a number of animal and human studies showed that contrast enhanced ultrasound can be also used for the detection of sentinel lymph node, and may become a potential application in clinical routine. Several contrast agents have been used in those studies, including albumin solution, hydroxyethylated starch, SonoVue®, Sonazoid® and Definity®. This review summarizes the current knowledge about the use of ultrasound techniques in detection and evaluation of sentinel lymph node.

    Currently, there is no agreement regarding if it would be necessary to perform an axillary lymph node dissection (ALND) in patients who have macrometastases in the sentinel lymph node (SLN). We studied the utility of the secondary node analysis (SN), defined as the following node after the SLN in an anatomical and lymphatic pathway, as a sign of malignant axillary involvement. An observational, retrospective and multicentre study was designed to assess the utility of the SN as a sign of axillary involvement. Among 2273 patients with breast cancer, a valid sample of 283 was obtained representing those who had the SN studied. Main endpoints of our study were: the SLN, the SN and the ALND histological pattern. Sensitivity, specificity and precision of the test were also calculated. SN test, in cases with positive SLN, has a sensitivity of 61.1%, a specificity of 78.7%, a positive predictive value of 45.8% and a negative predictive value of 87.3% with a precision of 74.7%. The study of the SN together with the technique of the SLN allows a more precise staging of the axillary involvement, in patients with breast cancer, than just the SLN technique.

    In penile cancer, the optimal diagnostics and management of metastatic lymph nodes are not clear. Advances in minimally invasive staging, including dynamic sentinel lymph node biopsy, have widened the diagnostic repertoire of the urologist. We aimed to provide an objective update of the recent trends in the management of penile squamous cell carcinoma, and inguinal and pelvic lymph node metastases. We systematically reviewed several medical databases, including the Web of Science® (with MEDLINE®), Embase® and Cochrane databases, according to PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) guidelines. The search terms used were penile cancer, lymph node, sentinel node, minimally invasive, surgery and outcomes, alone and in combination. Articles pertaining to the management of lymph nodes in penile cancer were reviewed, including original research, reviews and clinical guidelines published between 1980 and 2016. Accurate and minimally invasive lymph node staging is of the utmost importance in the surgical management of penile squamous cell carcinoma. In patients with clinically node negative disease, a growing body of evidence supports the use of sentinel lymph node biopsies. Dynamic sentinel lymph node biopsy exposes the patient to minimal risk, and results in superior sensitivity and specificity profiles compared to alternate nodal staging techniques. In the presence of locoregional disease, improvements in inguinal or pelvic lymphadenectomy have reduced morbidity and improved oncologic outcomes. A multimodal approach of chemotherapy and surgery has demonstrated a survival benefit for patients with advanced disease. Recent developments in lymph node management have occurred in penile cancer, such as minimally invasive lymph node diagnosis and intervention strategies. These advances have been met with a degree of controversy in the contemporary literature. Current data suggest that dynamic sentinel lymph node biopsy provides excellent

    A 20-year old patient who had been adequately treated for lymph node tuberculosis 14 years ago presented 1 week after giving birth to a healthy daughter. She complained about painful lumps in both axillae. During pregnancy the patient suffered from hyperemesis gravidarum, lost 6 kg of weight, and had night sweats. During the last three months of her pregnancy she had a deep vein thrombosis in her right lower leg. The clinical examination showed soft axillary lumps up to 3 cm. The lab showed the following pathological findings: blood sedimentation rate 51 mm/h, CRP 44.8 mg/l, LDH 221 U/l and INR 1.3 (indicating insufficient anticoagulation with phenprocoumon). The chest x-ray showed no infiltrate or indications of a past tuberculosis. A fine needle aspiration cytology was performed on an accessible node. Gram stain, Ziehl Neelsen stain, as well as the bacteriological cultures were all negative. An ultrasound examination of the axilla showed a thickened subcutis without a mass. Cytology showed lobular epithelium, consistent wih ductal mamma epithelium without atypical cells. The diagnosis of an accessory mamma tissue in both axillae was made. During the course of the following weeks the glands decreased in size and the patient was free of symptoms.

    In the past, most patient of breast cancer suffered side effects due to the useless removement of Axillary Lymph Node, but there is no need to remove it because of the result in this study. The purpose of this study is to save surgery time and side effects after surgical operation for patients with breast cancer by making decisions of operation range for metastasis in first Stenosis Lymph Node using the {sup 99m}Tc-Tincolloid Scintigraphy and the Micro Probe for radioisotope. As a result of this study, 15 among 20 patients became objects of this study could reduced side effects for operation because there were no axillary lymph node operations. However there is no standard for method of this treatment. It should be standardize where inject point is, how much {sup 99m}Tc-Tincolloid should be injected (radioactivity value), and the need of massage and Lymph Scintigraphy. Nevertheless I think that this result of study is useful to reduce suffering and side effects from breast cancer and also we should try to do that continuously. The objects for this study were 20 patients diagnosed as breast cancer by Ultrasonography, Mammography and Biopsy. The average of patient age was 45.4 years and its range was between 31 and 71 years. In case of clinical period there were 9 patients of Period I and 11 patients of Period II. The equipment for this study were {sup 99m}Tc-Tincolliod describing the Stenosis Lymph Node as a tracer. Micro Probe: Neoprobe 2000 (the rest is Gamma Probe) tracing the location, and MS-II Gamma Camera: SIEMENS (the rest is MS-II Gamma Camera) describing the image. There were 3 methods for this study, after selecting one of those methods all 20 patients were performed Stenosis Lymph Node diagnosis and Gamma Probe in operation room. The result was that I imaged all the 20 patients, and seek the Stenosis Lymph Node by using Gamma Probe. Metastasis in Stenosis Lymph Node was 5 and Metastasis in Axillary Lymph Node was 3 between Metastasis in Stenosis Lymph

The use of a non-porous retrieval bag, early recognition of the carcinoma and excision of the exit wound are advocated.

  3. The association of exosomes with lymph nodes.

    Cells produce extracellular nanovesicles known as exosomes that transport information between tissue microenvironments. Exosomes can engage and regulate the function of various immune cell types facilitating both normal and pathological processes. It follows that exosomes should also associate with lymph nodes containing immune cells. Herein, data derived from investigations that incorporate experiments pertaining to the trafficking of exosomes to lymph nodes is reviewed. Within lymph nodes, direct evidence demonstrates that exosomes associate with dendritic cells, subcapsular sinus macrophages, B lymphocytes and stromal cells. Interactions with endothelial cells are also likely. The functional significance of these associations depends on exosome type. Continued investigations into the relationship between exosomes and lymph nodes will further our understanding of how exosomes regulate immune cells subsets and may serve to inspire new exosome based therapeutics to treat a variety of diseases.

    Full Text Available The modern management of the axilla in breast cancer relies on surgery for accurate staging of disease and identifying those patients at risk who would benefit from adjuvant chemotherapy. The introduction of sentinel lymph node biopsy has revolutionized axillary surgery, but still involves a surgical procedure with associated morbidity in many patients with no axillary involvement. Nanotechnology encompasses a broad spectrum of scientific specialities, of which nanomedicine is one. The potential use of dual-purpose nanoprobes could enable imaging the axilla simultaneous identification and treatment of metastatic disease. Whilst most applications of nanomedicine are still largely in the laboratory phase, some potential applications are currently undergoing clinical evaluation for translation from the bench to the bedside. This is an exciting new area of research where scientific research may become a reality.

    The presence of pigment in axillary lymph nodes (LN) secondary to migration of tattoo ink can imitate the appearance of a blue sentinel lymph node (SLN) on visual inspection, causing the operator to either miss the true SLN or excise more than is needed. We present patients with tattoos ipsilateral to an early stage breast cancer who underwent a SLN biopsy. Patients were retrospectively reviewed from medical records and clinicopathologic data was collected. A total of 52 LNs were retrieved from 15 patients for sentinel mapping and 29 of them had tattoo pigmentation on pathologic evaluation. Of those 29 SLNs, 2 of them (6.9%) were pigmented, but did not contain either blue dye or Tc-99m (pseudopigmented SLN). Two (3.8%) SLNs were positive for metastasis; both of these had either blue dye or Tc99m uptake, and 1 demonstrated tattoo pigment in the node. In this cohort of patients with ipsilateral tattoos, removed more LNs lead to unnecessary excision which may important for increasing the risk of arm morbidity from SLN biopsy. However, the presence of tattoo pigment did not interfere with understaging for axillary mapping and it did not effect of pathological identification of SLNs positivity.

    Lymph nodes (LN's), located throughout the body, are an integral component of the immune system. They serve as a site for induction of adaptive immune response and therefore, the development of effector cells. As such, LNs are key to fighting invading pathogens and maintaining health. The choice of LN to study is dictated by accessibility and the desired model; the inguinal lymph node is well situated and easily supports studies of biologically relevant models of skin and genital mucosal infe...

    Background: Previous studies of CT enhancement of lymphomatous lymph nodes (LLN) of the neck and the mediastinum showed that the LLN had lower enhancement values than normal lymph nodes. Purpose: To elucidate the contrast medium enhancement curves of LLN in the retroperitoneum by comparing the curves of LLN with those of normal lymph nodes, to test whether differences between these curves could be of diagnostic value, and to compare the present enhancement curves of LLN of the retroperitoneum with the curves of LLN of the neck and the mediastinum from previous similar investigations. Material and Methods: Twenty-eight consecutive patients with LLN of the retroperitoneum (three with Hodgkin's lymphoma [HL]) and 21 control patients with sarcomas and thus presumably normal retroperitoneal nodes underwent dynamic CT examinations. The previous, similar investigation of lymph nodes of the neck comprised 28 patients with LLN and the investigation of mediastinal lymph nodes comprised 24 patients with LLN. Results: The enhancement curves of the retroperitoneal LLN had significantly lower attenuation than those of the retroperitoneal control nodes. A combination of peak contrast value and time to peak adjusted to total body weight yielded a diagnostic accuracy which at the best showed a sensitivity of 90.5% with a specificity of 82.6%. The LLN of the retroperitoneum had higher attenuation values than corresponding nodes of the mediastinum but no significant difference was found between LLN of the retroperitoneum and LLN of the neck in previous similar investigations. Conclusion: The comparison of enhancement curves of retroperitoneal LLN with retroperitoneal control nodes showed a marked similarity with and substantiates our previous findings in lymph nodes of the neck and of the mediastinum. The best diagnostic accuracy was achieved by combining the parameters peak contrast value and time to peak and adjusting these values to the body weight. Peak enhancement of the

    Full Text Available Abstract Background Phyllodes tumors (cystosarcoma phyllodes are uncommon lesions in the female breast. Rarely, the occurrence of carcinoma within a phyllodes tumor has been reported in the literature, but has never been associated with lymph node metastases. Case presentation A 26-year-old woman presented with a firm, mobile, non-tender mass in the left breast and palpable lymph nodes in the left axilla. The excised lesion appeared well circumscribed and lobulated, with variable fleshy and firm areas. Microscopic examination showed a circumscribed fibroepithelial lesion with a well developed leaf-like architecture, in keeping with a benign phyllodes tumor. The epithelial component showed extensive high grade ductal carcinoma in-situ (DCIS and invasive carcinoma of no special type, located entirely within the phyllodes tumor. Subsequent axillary lymph node dissection revealed metastatic carcinoma in four lymph nodes. Conclusions Although rare, phyllodes tumors may harbor DCIS and invasive carcinoma, with potential for lymph node metastasis.

    Sentinel lymph node biopsy (SLNB) is currently not recommended in pregnant patients with breast cancer due to radiation concerns. Twelve pregnant patients with breast cancer received low-dose (10 MBq on average) lymphoscintigraphy using {sup 99m}Tc human serum albumin nanocolloids. The sentinel lymph node (SLN) was identified in all patients. Of the 12 patients, 10 had pathologically negative SLN. One patient had micrometastasis in one of four SLN. One patient had metastasis in the SLN and underwent axillary clearance. From the 12 pregnancies, 11 healthy babies were born with no malformations and normal weight. One baby, whose mother underwent lymphatic mapping during the 26th week of gestation, was operated on at the age of 3 months for a ventricular septal defect and at 43 months was in good health. This malformation was suspected at the morphological US examination during week 21, well before lymphoscintigraphy, and was confirmed a posteriori by a different observer based on videotaped material. No overt axillary recurrence appeared in the patients with negative SLNs after a median follow-up of 32 months. Our experience supports the safety of SLNB in pregnant patients with breast cancer, when performed with a low-dose lymphoscintigraphic technique. (orig.)

    Stage III melanoma is currently stratified by number of lymph nodes (LNs) involved. However, given the variability of LN retrieval counts we hypothesize that lymph node ratio (LNR) may also provide prognostic information. Retrospective cohort study of 411 patients with stage III melanoma were divided into two groups based on LNR (analysis N stage (N3 vs. N1, hazard ratio [HR] = 2.13, p 8 inguinal, >15 axillary, or >20 cervical LNs examined had fewer same nodal basin recurrences (26 [8 %] vs. 20 [20 %], p = 0.0009) and for N1 patients an improved OS (3-year OS 84 % vs. 76 %, 10-year OS 53 % vs. 34 %, p = 0.06) compared with N1 patients who had fewer LNs examined. LNR is an important prognostic factor in stage III melanoma; however, it was not independent over the current AJCC TNM staging system. Diligence by the surgeon and pathologist to retrieve and examine >8 inguinal, >15 axillary, or >20 cervical LNs is associated with fewer same nodal basin recurrences and improved survival and is critical to reliable prognostication.

    A 71-year-old man operated for a sigmoid tumour remained in the surveillance after adjuvant chemotherapy. After 3 years, a left axillary lymph node was visible on CT scan. The biopsy revealed a necrotising and abscessed granulomatous lymphadenitis, suggestive of cat scratch disease. The patient confirmed having been scratched by a cat and the serology for Bartonella henselae was IgM+/IgG-. Direct and culture examinations for tuberculosis were negative. The patient was treated for cat scratch disease. One year later, the CT scan showed increased left axillary lymph nodes and a left pleural effusion. Direct and cultural examinations to exclude tuberculosis were again negative. Interferon-γ release assay testing for tuberculosis was undetermined and then positive. Lymph node and pleural tuberculosis were diagnosed and treated with a good radiological response. This article has provides evidence of the importance of continued search for the right diagnosis and that two diagnoses can happen in the same patient.

    Full Text Available Abstract Background One of the most exciting and talked about new surgical techniques in breast cancer surgery is the sentinel lymph node biopsy. It is an alternative procedure to standard axillary lymph node dissection, which makes possible less invasive surgery and side effects for patients with early breast cancer that wouldn't benefit further from axillary lymph node clearance. Sentinel lymph node biopsy helps to accurately evaluate the status of the axilla and the extent of disease, but also determines appropriate adjuvant treatment and long-term follow-up. However, like all surgical procedures, the sentinel lymph node biopsy is not appropriate for each and every patient. Methods In this article we review the absolute and relative contraindications of the procedure in respect to clinically positive axilla, neoadjuvant therapy, tumor size, multicentric and multifocal disease, in situ carcinoma, pregnancy, age, body-mass index, allergies to dye and/or radio colloid and prior breast and/or axillary surgery. Results Certain conditions involving host factors and tumor biologic characteristics may have a negative impact on the success rate and accuracy of the procedure. The overall fraction of patients unsuitable or with multiple risk factors that may compromise the success of the sentinel lymph node biopsy, is very small. Nevertheless, these patients need to be successfully identified, appropriately advised and cautioned, and so do the surgeons that perform the procedure. Conclusion When performed by an experienced multi-disciplinary team, the SLNB is a highly effective and accurate alternative to standard level I and II axillary clearance in the vast majority of patients with early breast cancer.

    Sentinel lymph node (SLN) biopsy is the standard of care for axillary staging in invasive breast cancer. The introduction of SLN biopsy with an extensive pathology examination, in addition to the introduction of the 2002 TNM classification, led to different axillary classification outcomes. We evaluated the effect of axillary staging procedures and subsequent axillary nodal status in patients with invasive lobular carcinoma (ILC) versus invasive ductal carcinoma (IDC) from 1998 to 2013. The use of SLN biopsy and the nodal status distribution were analyzed in patients with stage T1-T2 ILC and IDC. Logistic regression analysis was performed to determine the independent effect of histologic type on the probability of the presence of isolated tumor cells (ITCs), micrometastases, and macrometastases. A total of 89,971 women were diagnosed, 10,146 with ILC (11%) and 79,825 with IDC (89%). The patients who had undergone SLN biopsy were more frequently diagnosed with ITCs than were those who had undergone axillary lymph node dissection only (odds ratio, 8.8; 95% confidence interval, 7.0-11.2). In 2013, the proportion of patients with ITCs in the axillary nodes was 8% in those with ILC and 4.4% in those with IDC. Patients with ILC were significantly more likely to have ITCs in their axillary lymph nodes than were patients with IDC (odds ratio, 1.8; 95% confidence interval, 1.6-2.0). With the introduction of SLN biopsy and the renewed 2002 TNM classification, patients with ILC have been more frequently diagnosed with ITCs than have patients with IDC. The clinical consequence of this finding must be established from further research. Copyright © 2016 Elsevier Inc. All rights reserved.

    Molecular subtype of breast cancer is associated with sentinel lymph node status. We sought to establish a mathematical prediction model that included breast cancer molecular subtype for risk of positive non-sentinel lymph nodes in breast cancer patients with sentinel lymph node metastasis and further validate the model in a separate validation cohort. We reviewed the clinicopathologic data of breast cancer patients with sentinel lymph node metastasis who underwent axillary lymph node dissection between June 16, 2014 and November 16, 2017 at our hospital. Sentinel lymph node biopsy was performed and patients with pathologically proven sentinel lymph node metastasis underwent axillary lymph node dissection. Independent risks for non-sentinel lymph node metastasis were assessed in a training cohort by multivariate analysis and incorporated into a mathematical prediction model. The model was further validated in a separate validation cohort, and a nomogram was developed and evaluated for diagnostic performance in predicting the risk of non-sentinel lymph node metastasis. Moreover, we assessed the performance of five different models in predicting non-sentinel lymph node metastasis in training cohort. Totally, 495 cases were eligible for the study, including 291 patients in the training cohort and 204 in the validation cohort. Non-sentinel lymph node metastasis was observed in 33.3% (97/291) patients in the training cohort. The AUC of MSKCC, Tenon, MDA, Ljubljana, and Louisville models in training cohort were 0.7613, 0.7142, 0.7076, 0.7483, and 0.671, respectively. Multivariate regression analysis indicated that tumor size (OR = 1.439; 95% CI 1.025-2.021; P = 0.036), sentinel lymph node macro-metastasis versus micro-metastasis (OR = 5.063; 95% CI 1.111-23.074; P = 0.036), the number of positive sentinel lymph nodes (OR = 2.583, 95% CI 1.714-3.892; P model based on the results of multivariate analysis was established to predict the risk of non

    Sentinel lymph node (SLN) biopsy is a reliable technique for determining axillary status in patients with early breast cancer. This technique is a minimally invasive procedure that can avoid the use of lymphadenectomy in patients without axillary involvement. We present a validation study of SLN biopsy with subareolar injection of 99mTc-nanocolloids. We studied 100 patients with early breast cancer (T1 and T2) over a 2-year period. All patients underwent deep subareolar-injection of 99mTc-nanocoloid for localization of the sentinel node. Images were obtained and when the sentinel node was seen, it was marked on the skin. All patients underwent tumor excision and radioguided SLN biopsy followed by complete lymphadenectomy. Histopathological analysis of sentinel nodes was performed by hematoxylin-eosin and immunohistochemistry with cytokeratins. The sentinel node was identified in all patients, and a mean of 1.95 sentinel nodes per patient were found. Lymphatic metastases in the sentinel node were found in 44 patients and in 15 of these tumoral spread was also found in the remaining axillary nodes. In the 56 remaining patients the sentinel node was free of metastasis, but in two of them a non-sentinel node was found to be positive (4.5% false negative rate). Sensitivity was 95.7% (44/46), specificity was 100% (54/54), the positive predictive value was 100% and the negative predictive value was 96.4% (54/56). SLN biopsy is an accurate alternative to complete axillary lymph node dissection in patients with early-stage breast cancer. This technique improves the staging of these patients and decreases the morbidity associated with lymphadenectomy. The advantages of subareolar injection are that a single injection site is required, the tumor does not have to be located by other techniques, it allows rapid visualization of the sentinel node and avoids the "shine through phenomenon" when the tumor is located near the axilla.

This treatment planning study evaluates the reduction in cardiopulmonary doses when radiation is given during deep inspiration breath-hold (DIBH). This was achieved without compromising dose coverage to the planning target volume (PTV). Seventeen patients with early breast cancer, referred for adjuvant radiotherapy, were included. For each patient two computed tomography (CT)-scans were acquired; the first during free breathing (FB) and the second during DIBH. The scans were monitored by the Varian RPM respiratory gating system. Audio-visual guidance was used. The treatment planning of the two CT studies was performed focusing on good coverage (V95% > 98%) of the PTV. Doses to the heart, left anterior descending (LAD) coronary artery, lungs and contralateral breast were assessed. With equal PTV coverage, average mean heart dose was reduced from 6.2 Gy to 3.1 Gy in DIBH plans as compared to FB. Average volume receiving 25 Gy or more (V25Gy) was reduced from 6.7% to 1.2%, and the number of patients with V25Gy > 5% was reduced from 8 to 1 utilizing DIBH. The average mean dose to the LAD coronary artery was reduced from 25.0 Gy to 10.9 Gy. The average ipsilateral lung volume receiving 20 Gy or more (V20Gy) was reduced from 44.5% to 32.7% with DIBH. In 11 of the DIBH plans V20Gy was lower than 35%, in accordance with national guidelines, while none of the FB plans fulfilled this recommendation. Respiratory gated radiotherapy during DIBH is a suitable technique for loco-regional breast irradiation even when IMC lymph nodes are included in the PTV. Cardiopulmonary doses are considerably decreased for all dose levels without compromising the dose coverage to PTV.

    Full Text Available Aim: Sentinel lymph node biopsy (SLNB in breast cancer patients targets the evaluation of the initial lymph node (SLN which drains the primary tumor. The morbidity of unnecessary axillary dissection can be avoided by intensive preoperative assessment of SLN. Methods: Twenty-six consecutive patients who had been surgically treated for early-stage breast cancer between March 2005 and August 2007 were evaluated. Blue dye (methylene blue method was used to detect SLN. All patients underwent axillary lymph node dissection following SLNB. NCSS program was used for statistical analysis. Chi-square test was used in the comparison of binary groups. Results: Except for one, all patients were female. The mean age of the patients was 56 (29-76 years. While 13 patients underwent modified radical mastectomy (=mastectomy+axillary dissection, the remaining 13 patients underwent breast preserving surgery (lumpectomy+axillary dissection. SLN could not be found in 2 patients (7.6%.The male patient was one of these 2 patients and both of them were positive for axillary node metastases. The detection rate of SLN, specificity, negative predictive value, positive predictive value, sensitivity, false negativity, and reliability were 92.3%, 92.8%, 86%, 90.9%, 83.3%, 16.6%, and 88.4%, respectively. Conclusion: Our result support the hypothesis that SLNB with blue dye alone is a reliable technique and, surgery clinics should use it prior to axillary dissection to test their own success during the learning curve.

    Sentinel lymph node (SLN) biopsy has been well-established for axillary lymph node staging for patients with breast cancer. For lymph node-negative patients, planned "backup" axillary lymph node dissection (ALND) is rarely indicated. Among patients with negative SLNs, the authors observed variation by tumor size and patient age in the total number of lymph nodes removed (SLNs plus non-SLNs). They hypothesized that this variation is an unrecognized source of bias for studies examining the morbidity of SLN biopsy. Retrospective review of this institution's SLN database identified 4103 SLN biopsy procedures between 1997 and 2004 in which SLN biopsy was performed for prophylactic mastectomy, ductal carcinoma in situ, or T1 to T2 invasive cancers, and the SLNs were benign. The mean number of SLNs, non-SLNs, and total lymph nodes for all tumor sizes was 2.8, 1.5, and 4.3, respectively, and increased with tumor size (more lymph nodes were removed for T2 than for T1 tumors: 6.3 vs 4.3; P 50 years (4.6 lymph nodes vs 4.2 lymph nodes; P = .006). In approximately 8% of patients (322 of 4103 patients), >or=10 lymph nodes were removed. The morbidity of SLN biopsy is less than that of ALND, but for pN0 patients, the total number of lymph nodes removed increased with tumor size and younger patient age. This variation is a previously unrecognized source of bias for studies that examine the morbidity of SLN biopsy. (c) 2010 American Cancer Society.

    While PET using F-FDG is most commonly used for imaging malignant tumors, vaccination is known to cause transient inflammation of lymph nodes inducing positive findings on F-FDG PET scans. The pattern, magnitude, and duration of lymph node activation following vaccination have not been clearly defined. Furthermore, the addition of adjuvants to vaccines can further enhance the immune response. The presented study was designed to define lymph node activation following administration of the Food and Drug Administration-licensed human papillomavirus vaccines, Cervarix and Gardasil, which contain similar antigens with different adjuvants. Twenty-seven women aged 18 to 25 years were randomized to receive either Cervarix or Gardasil in the clinical trial VRC 900. Fifteen subjects participated in the PET/CT portion of the trial and received scans of lymph node activation at prevaccination and "1 week" (8-14 days) and "1 month" (23-36 days) after the first or third vaccination. PET/CT scans revealed that all vaccine recipients had ipsilateral axillary lymph node activity. Three of 4 Cervarix recipients also showed contralateral lymph node activity 1 month after the first vaccination. For both Cervarix and Gardasil, the SUV activity resolved over time, with activity extended up to day 37 after the first and third vaccinations. Following intramuscular vaccination, there were no major differences between duration of uptake and intensity of SUV between Cervarix and Gardasil recipients in ipsilateral axillary lymph nodes. Contralateral node activation was detected up to 1 month after the first vaccination in Cervarix recipients only, possibly reflecting differences in vaccine adjuvant formulation.

    Full Text Available Sarcoidosis is a multiorgan granulomatous disease, the most common head and neck manifestation of which is cervical lymphadenopathy. Only the presentation of sarcoidal granuloma in cervical lymph nodes without typical manifestations of systemic sarcoidosis poses a diagnostic difficulty. We describe the case of a 39-year-old male who had a 2-month history of a progressively increasing mass with soreness in his right neck. The biopsy from the neck mass demonstrated non-caseating epithelioid cell granuloma of the lymph nodes. The differential diagnoses of mycobacterial or fungal infections were excluded. Thoracic evaluations, including chest X-ray and high-resolution computed tomography, revealed no abnormal findings. Treatment with systemic corticosteroids resulted in improved clinical symptoms. No recurrence of the neck mass or other signs of systemic sarcoidosis were noted during 1.5 years of follow-up. Although our patient's definitive diagnosis could not be determined, the case highlights 2 important issues: sarcoidal granuloma in lymph nodes may be a precursor of sarcoidosis, even in the absence of pulmonary or other systemic involvement; and regular follow-up is recommended in such cases.

    Patients with lymph node-negative gastric cancer show a better overall survival rate than those who have a pathological lymph node-positive gastric cancer. But a large number of patients still develop recurrence. We aimed to explore the significant prognostic factors of lymph node-negative gastric cancer and determine how many lymph nodes should be removed. A total of 3103 patients who underwent radical operation are identified from the Surveillance, Epidemiology, and End Results database. Standard survival methods and restricted multivariable Cox regression models were applied. The overall survival rate was significantly higher with an increasing number of negative lymph node resected. Among the 843 patients who had the exact T stage, the overall survival rate was significantly better in T3-4 group with more than 15 lymph nodes resected (P patients (P = 0.44). A further 25 more lymph nodes resection did not show additional survival benefits. Multivariate analysis of patients demonstrated that age, depth of tumor invasion, and the number of lymph nodes resected were the significant and independent prognostic factors. A lymphadenectomy with more than 15 lymph nodes removal should be performed for T3-4 lymph node-negative gastric cancer. But the survival benefit of a lymphadenectomy with more than 25 lymph nodes removal is disputed. And the further treatment should refer to the prognostic indicators.

    Full Text Available INTRODUCTION: Intraoperative frozen section analysis has become a routine procedure to evaluate the status of axillary sentinel lymph nodes in breast cancer. OBJECTIVES: To evaluate the accuracy and sensitivity of FS in the detection of metastases in axillary sentinel lymph nodes and to investigate the predictive value of variables such as patients' age, tumor staging, histology, grade, and estrogen receptor expression. MATERIAL AND METHODS: We analyzed retrospectively the results of 177 FS procedures. The patients' age and tumor characteristics were organized in a database and the association with the presence of metastases was analyzed. RESULTS: Metastases were detected in 22 cases (12%. All macrometastases and one micrometastasis were detected by FS. Additional micrometastases were detected in post-operative analysis, from which five were determined by hematoxylin and eosin staining (H and three by immunohistochemistry (IHC. FS diagnosis data proved to have an overall accuracy of 95%, sensitivity of 64%, and specificity of 100%. None of the analyzed variables showed significant association with lymph node metastases. CONCLUSION: Our results show that intraoperative FS is a highly accurate and sensitive method to detect macrometastases. However, it is inaccurate in the detection of micrometastases. The use of IHC improves the detection of micrometastases in postoperative analyses. The patient's age and tumor characteristics such as staging, histology, grade and estrogen receptor expression have low predictive value for lymph node metastasis in breast cancer.INTRODUÇÃO: O exame intraoperatório por congelação tornou-se um procedimento de rotina na avaliação do linfonodo sentinela axilar no câncer de mama.

    A 21-gene recurrence score (RS) assay may inform adjuvant systematic treatment decisions in women with early stage breast cancer. We sought to investigate the cost effectiveness of using the RS-assay versus current clinical practice (CCP) in women with early-stage estrogen- or progesterone-receptor-positive, axilliary lymph-node negative breast cancer (ER+/ PR + LN- ESBC) from the perspective of the Canadian public healthcare system. We developed a Markov model to project the lifetime clinical and economic consequences of ESBC. We evaluated adjuvant therapy separately in post- and pre-menopausal women with ER+/ PR + LN- ESBC. We assumed that the RS-assay would reclassify pre- and post-menopausal women among risk levels (low, intermediate and high) and guide adjuvant systematic treatment decisions. The model was parameterized using 7 year follow up data from the Manitoba Cancer Registry, cost data from Manitoba administrative databases, and secondary sources. Costs are presented in 2010 CAD. Future costs and benefits were discounted at 5%. The RS-assay compared to CCP generated cost-savings in pre-menopausal women and had an ICER of $60,000 per QALY gained in post-menopausal women. The cost effectiveness was most sensitive to the proportion of women classified as intermediate risk by the RS-assay who receive adjuvant chemotherapy and the risk of relapse in the RS-assay model. The RS-assay is likely to be cost effective in the Canadian healthcare system and should be considered for adoption in women with ER+/ PR + LN- ESBC. However, ongoing assessment and validation of the assay in real-world clinical practice is warranted

    From 1994 to 1995, to evaluate the utility of preoperative CT, EUS (endoscopic ultrasonography) and US in the diagnosis of lymph node metastasis in thoracic esophageal cancer, 94 patients with thoracic esophageal cancer who underwent esophagectomy were studied clinicopathologically. The sensitivity of EUS diagnosis of upper mediastinal lymph node metastasis (85%), left-sided paragastrin lymph node metastasis (73-77%), and especially lower paraesophageal lymph node metastasis (100%) were good. But due to their low-grade specificity in EUS diagnosis, their overall accuracy was not very good. On the other hand, the overall accuracy of the CT diagnosis of lymph node metastasis was fine. However, sensitivity, the most important clinical factor in the CT diagnosis of lymph node metastasis was considerably inferior to EUS. The assessment of the diagnosis of lymph node metastasis around the tracheal bifurcation and the pulmonary hilum and the left para-cardial lesion by CT or EUS was poor. It was concluded that lymph node metastasis of these area must be the pitfall in preoperative diagnosis. The average diameter of the lymph nodes and the proportion of cancerous tissue in the lymph nodes diagnosed as metastatic lymph nodes by CT was larger than that of the false negative lymph nodes. However, the lymph nodes diagnosed as true positives by EUS showed no such tendency. This must be the reason the sensitivity of the EUS diagnosis and specificity of the CT diagnosis were favorable, but the specificity of the EUS diagnosis and especially the sensitivity of the CT diagnosis were not as good.

    2006-01-01

    Background and purpose: Sentinel lymph node biopsy has been proven to be successful and accurate in predicting the nodal status in melanoma and breast cancer. Occult lymph node metastases are common in well differentiated thyroid cancer (WDTC). Although the prognostic significance of these occult lymph node metastases remains controversial, identifying these patients may help direct therapy. The purpose of the study was to assess the technical feasibility and the safety of the sentinel lymph node biopsy in uni-nodular thyroid disease. Methods: Patients of previously untreated benign solitary thyroid nodule, diagnosed preoperatively by fine needle aspiration cytology without any palpable cervical lymph node were prospectively studied. The nodule was injected with iso sulfan blue vital dye. Blue stained lymphatics were traced. Then, hemi thyroidectomy was per-formed. Results: A total of 30 patients underwent sentinel lymph node biopsy; lymph tics were observed in 23 patients and sentinel lymph nodes were found in 18. In 5 patients, blue stained lymphatics were traced to the outside of the central compartment but no sentinel lymph node was identified. Sentinel lymph nodes were located in the central compartment in 14 cases, in the lateral compartment in 3 cases and in one patient 2 sentinel lymph nodes were found in both the central and the lateral compartments. Overall detection of sentinel lymph nodes was possible in 60% of cases. There were no intra or postoperative complications. Conclusions: The role of sentinel lymph node biopsy has yet to be determined in the thyroid setting. Certainly the technique can be performed safely, but its accuracy needs further refinement and investigation on larger series of patients before it can be recommended in the routine management of thyroid neoplasia.

    Tuberculosis (TC) is very common and significant cause of morbidity and mortality worldwide. Isolated cystic duct lymph node TC cases without involvement of gallbladder are exceedingly rare. It is difficult to diagnose preoperatively because of lack of characteristic signs and symptoms of TC. We report a man aged 45 years who presented with right upper abdominal pain since 1week. It was associated with nausea and postprandial fullness. There was no evidence of jaundice and lymphadenopathy. Abdominal examination showed moderate right upper quadrant tenderness with positive Murphy's sign and splenomegaly but no signs of peritonism. Abdomen ultrasound revealed sludge in gallbladder, dilated pancreatic duct, coarse exotexture of liver, splenomegaly and no lymphadenopathy. He underwent laparoscopic cholecystectomy; histological report showed chronic caseating granulomatous lymphadenitis with Langhans type of giant cells in lymph node near cystic duct with chronic cholecystitis of gallbladder. Standard antituberculosis therapy was given for 12 months. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    Sentinel lymph node biopsy (SLNB) has been emerged as a highly accurate method of axillary staging in management of breast cancer patients. Sentinel lymph node detection (SLND) by lymphoscintigraphy and intra-operative gamma probe for SLNB have been widely used in the world. Objectives: the purpose of our study was to evaluate the result of techniques using lymphoscintigraphy and intra-operative gamma probe for SLND in breast carcinoma patients. Materials and Methods: 102 patients with early breast carcinoma were enrolled in the study. Lymphoscintigraphy using Tc-99m-human serum albumin colloid, intra-operative gamma probe were undergone for localization and SLNB. Total axillary lymph node was dissected in breast cancer surgery. Results: The success rate of lymphoscintigraphy and SLND was 98.0% (100/102 patients), mean number of sentinel lymph node (SLN)/patient was 1.56 ± 0.79 (ranged 1 - 3), number of lymphatic vessel/SLN was 1.5 ± 0.69 (ranged 1 - 4) and mean time for SLND on lymphoscintigraphy was 4.21 ± 13.4 minutes (2 - 15 minutes). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of radio-guided SLNB for axillary staging was 100%, 70.6%, 41.2%, 100% and 75.6 % respectively. Conclusions: radio-guided SLNB by lymphoscintigraphy and intra-operative gamma probe is feasible and reliable for axillary staging in early breast carcinoma patients. (author)

    The ability to reliably detect sentinel lymph nodes for sentinel lymph node biopsy and lymphadenectomy is important in clinical management of patients with metastatic cancers. However, the traditional sentinel lymph node mapping with visible dyes is limited by the penetration depth of light and fast clearance of the dyes. On the other hand, sentinel lymph node mapping with radionucleotide technique has intrinsically low spatial resolution and does not provide anatomic details in the sentinel lymph node mapping procedure. This work reports the development of a dual modality imaging probe with magnetic resonance and near infrared imaging capabilities for sentinel lymph node mapping using magnetic iron oxide nanoparticles (10 nm core size) conjugated with a near infrared molecule with emission at 830 nm. Accumulation of magnetic iron oxide nanoparticles in sentinel lymph nodes leads to strong T2 weighted magnetic resonance imaging contrast that can be potentially used for preoperative localization of sentinel lymph nodes, while conjugated near infrared molecules provide optical imaging tracking of lymph nodes with a high signal to background ratio. The new magnetic nanoparticle based dual imaging probe exhibits a significant longer lymph node retention time. Near infrared signals from nanoparticle conjugated near infrared dyes last up to 60 min in sentinel lymph node compared to that of 25 min for the free near infrared dyes in a mouse model. Furthermore, axillary lymph nodes, in addition to sentinel lymph nodes, can be also visualized with this probe, given its slow clearance and sufficient sensitivity. Therefore, this new dual modality imaging probe with the tissue penetration and sensitive detection of sentinel lymph nodes can be applied for preoperative survey of lymph nodes with magnetic resonance imaging and allows intraoperative sentinel lymph node mapping using near infrared optical devices.

    Melanoma preferentially spreads via lymph nodes. Melanoma exosomes can induce angiogenesis and immune suppression. However, a role for melanoma exosomes in facilitating tumor tolerance in lymph nodes has not been considered. Herein, the hypothesis that melanoma exosome mediated induction of vascular endothelial cell (VEC) derived TNF-α results in lymphatic endothelial cell (LEC) mediated tumor tolerance is explored.

    Objective: The aim of the current study is to determine the clinical value of incidental internal mammary lymph node biopsy in free abdominal flap breast reconstruction using internal mammary vessels as recipient vessels and to investigate the risk factors of internal mammary lymph nodes metastasis. Methods: The clinical data of all patients who underwent free abdominal flap breast reconstruction using internal mammary vessels as recipient vessels from November 2006 to December 2015 in the Department of Breast Surgery, Fudan University Shanghai Cancer Center were reviewed in the study. The incidence of internal mammary lymph node biopsy and the rate of metastasis were analyzed. Statistical analysis was conducted to evaluate the risk factors of internal mammary lymph node metastasis. Results: A total of 113 patients met the inclusion criteria, 53 (46.9%) of whom had internal mammary lymph nodes harvested. Four of these were positive for metastatic disease, all in immediate breast reconstructions. The incidence of metastasis was 7.5% in patients who had successful internal mammary lymph node biopsies.The multi-variate Logistic regression analysis showed that invasive tumor size, tumor location and axillary lymph node metastasis were not risk factors for internal mammary lymph node metastasis ( P >0.05). Conclusions: Internal mammary lymph nodes found incidentally during recipient vessel exposure may provide important information about internal mammary lymph node metastasis in free flap breast reconstruction. This approach for internal mammary lymph node biopsy reveals an appreciable success rate and is convenient in clinical practice. The size of invasive tumor and the axillary lymph node metastasis are probably associated with internal mammary lymph node positivity.

    Full Text Available Objective: Patients with locally advanced breast cancer may undergo breast conserving surgery after neoadjuvant chemotherapy. The aim of the study is to evaluate the results of locally advanced breast cancer patients who underwent breast conserving surgery, axillary dissection and sentinel lymph node biopsy in a single center. Material and Methods: 12 patients with locally advanced breast cancer stage IIIA/IIIB were included in the study between 2002-2009. The patients were given anthracycline-based regimen before surgery. Patients underwent breast conserving surgery, axillary dissection, and sentinel lymph node biopsy followed by radiotherapy. Results: There were five patients in stage IIIA, six in stage IIIB, and one in stage IIIC. Patients had received 3-6 regimen of FAC/FEC. Eight had partial and four had complete response. Five positive axilla were detected. The median value of the lymph nodes was 12 (n:8-19. Five patients underwent sentinel lymph node biopsy. The biopsy has failed in one patient and the median value of dissected sentinel node was 3.5 (n:3-4. Locoregional recurrence was not observed in any patients. The mean follow-up of the patients was 29.8 months and median time was 16 (n:2-80 months.Of the 12 patients 10 are alive and 2 were deceased. Conclusion: In selected locally advanced patients, breast conserving surgery and sentinel lymph node biopsy may be applied by a multidisciplinary approach, and excellent success may be achieved in those patients as in early breast cancer patients.

    Lymph nodes (LN's), located throughout the body, are an integral component of the immune system. They serve as a site for induction of adaptive immune response and therefore, the development of effector cells. As such, LNs are key to fighting invading pathogens and maintaining health. The choice of LN to study is dictated by accessibility and the desired model; the inguinal lymph node is well situated and easily supports studies of biologically relevant models of skin and genital mucosal infection. The inguinal LN, like all LNs, has an extensive microvascular network supplying it with blood. In general, this microvascular network includes the main feed arteriole of the LN that subsequently branches and feeds high endothelial venules (HEVs). HEVs are specialized for facilitating the trafficking of immune cells into the LN during both homeostasis and infection. How HEVs regulate trafficking into the LN under both of these circumstances is an area of intense exploration. The LN feed arteriole, has direct upstream influence on the HEVs and is the main supply of nutrients and cell rich blood into the LN. Furthermore, changes in the feed arteriole are implicated in facilitating induction of adaptive immune response. The LN microvasculature has obvious importance in maintaining an optimal blood supply to the LN and regulating immune cell influx into the LN, which are crucial elements in proper LN function and subsequently immune response. The ability to study the LN microvasculature in vivo is key to elucidating how the immune system and the microvasculature interact and influence one another within the LN. Here, we present a method for in vivo imaging of the inguinal lymph node. We focus on imaging of the microvasculature of the LN, paying particular attention to methods that ensure the study of healthy vessels, the ability to maintain imaging of viable vessels over a number of hours, and quantification of vessel magnitude. Methods for perfusion of the microvasculature

    Full Text Available Introduction: Mammary gland tumours occupy a significant place in the pathology of this species. Female dogs that are not spayed after their first heat cycle have a higher predisposition of developing mammary tumours. Most tumours metastasize at distance via the lymphatic system. In these conditions, the sentinel lymph nodes of the mammary glands must be assessed prior to surgical treatment. Aims: Considering the insufficient usage of non-invasive investigative methods of the sentinel lymph nodes, the aim of this study is to describe the sonographic anatomy of the lymph nodes that drain the mammary gland tumours in female dog. Materials and Methods: Twelve dog females presenting tumours of the cranial and caudal abdominal mammary glands (A1 and A2, inguinal mammary gland (I and cranial thoracic mammary gland (T1 were examined (group I. In addition, a control group composed of eight dog females was used (group II. The axillary and superficial inguinal lymph nodes were evaluated using an algorithm composed of gray-scale ultrasound, Doppler technique, contrast enhanced ultrasound (CEUS and real time elastography. Surgical excision of the sentinel lymph nodes was performed and samples for histopathological examination were taken. Results: The following ultrasonographic findings revealed on gray-scale examination were suspected for the metastatic infiltration: hypoechoic pattern, round shape, hillus absence and heterogenicity. Doppler technique showed an aberrant and mixed vascularisation of the lymph nodes, while the CEUS revealed incomplete enhancement of lymph nodes parenchyma. On real time elastography, the presence of blue areas in more than 50% from the lymph nodes parenchyma led us to conclude that the lymph node stiffness was caused by metastatic infiltration. Histopathological examination confirmed the presence of the metastatic infiltration in 97% of the examined lymph nodes. Conclusion: The algorithm composed of gray-scale ultrasound

    morphological (12 and Doppler velocimetry (17 ultrasonographic features, in the detection of lymph node metastases in breast cancer patients. METHODS: 179 women (181 axillary cavities were included in the study from January to December 2004. The ultrasonographic examinations were performed with a real-time linear probe (Toshiba-Power Vision-6000 (model SSA-370A. The morphological parameters were studied with a frequency of 7.5-12 MHz. A frequency of 5 MHz was used for the Doppler velocimetry parameters. Subsequently, the women were submitted to level I, II and III axillary dissection (158, or to the sentinel lymph node technique (23. Sensitivity, specificity, and positive and negative predictive values were calculated for each parameter. The decision tree test was used for parameter association. The cutoff points were established by the ROC curve. RESULTS: at least one lymph node was detected in 173 (96% of the women by the ultrasonographic examinations. Histological examination detected lymph node metastases in 87 women (48%. The best sensitivity among the morphological paramenters was found with the volume (62%, the antero-posterior diameter (62% and the fatty hilum placement (56%. Though the specificity of the extracapsular invasion (100%, border regularity (92% and cortex echogenicity (99% were high, the sensitivity of these features was too low. None of the Doppler velocimetry parameters reached 50% sensitivity. The decision tree test selected the ultrasonographic parametners: fatty hilum placement, border regularity and cortex echogenicity, as the best parameter association. CONCLUSION: the detection of axillary cavity lymph node stage by a noninvasive method still remains an unfulfilled goal in the treatment of patients with breast cancer.

    Full Text Available The number of breast cancer cases undergoing sentinel lymph node biopsy (SLNB has been increasing with the number of articles published in Japan. SLNB using the dye method alone is performed in about one-third of patients. Analysis of questionnaire responses from 40 institutions in Japan revealed an identification rate by the dye method alone of 87%, compared with 96% using the combined method; the combined method is now recognized in Japan as superior to the dye method alone. No dyes have been specifically approved by the government for use in SLNB, and physicians have been using several inappropriate dyes as tracers for SLNB, such as indocyanine green, patent blue, indigo carmine, and isosulfan blue. The colloidal radiotracers used in Japan include tin colloid, stannous phytate, rhenium sulfate and human serum albumin. Albumin colloid and sulfur colloid are not commercially available in Japan. Small-size tin colloids, stannous phytate and rhenium sulfate all yield good results in terms of detection and false-negative rates. Provided that the surgeon has adequate experience in SLNB, a negative sentinel node can serve as a substitute for negative results from axillary lymph node dissection. Although many institutions have introduced SLNB, few reports have focused on the results of SLNB without axillary dissection because of short follow-up times and small number of patients. The final decision as to whether SLNB is an adequate substitute for axillary dissection awaits the results of prospective randomized trials.

    Full Text Available Over the last decades, breast cancer treatment has become more personalised. Treatment plans are based on the biology of the tumour rather than the stage. Consequently, neoadjuvant chemotherapy (NACT is commonly the primary therapy for early breast cancer as well as locally advanced disease. Sentinel lymph node biopsy (SLNB is standard axillary management for women with node-negative disease. This review looks at the relevant literature and gives guidance on the timing of SLNB when NACT is planned and evaluates the safety of performing an SLNB rather than an axillary clearance.

    Radiation therapy to the breast following breast conservation surgery has been the standard of care since randomized trials demonstrated equivalent survival compared to mastectomy and improved local control and survival compared to breast conservation surgery alone. Recent controversies regarding adjuvant radiation therapy have included the potential role of additional radiation to the regional lymph nodes. This review summarizes the evolution of regional nodal management focusing on 2 topics: first, the changing paradigm with regard to surgical evaluation of the axilla; second, the role for regional lymph node irradiation and optimal design of treatment fields. Contemporary data reaffirm prior studies showing that complete axillary dissection may not provide additional benefit relative to sentinel lymph node biopsy in select patient populations. Preliminary data also suggest that directed nodal radiation therapy to the supraclavicular and internal mammary lymph nodes may prove beneficial; publication of several studies are awaited to confirm these results and to help define subgroups with the greatest likelihood of benefit

    To identify the genes involved in the carcinogenesis and progression of colorectal cancer, we analyzed the gene-expression profiles of colorectal cancer cells from 12 tumors with corresponding noncancerous colonic epithelia using a cDNA microarray representing 4,08 genes. We classified both samples and genes by using a two-way clustering analysis and identified genes that were differentially expressed in the cancerous and noncancerous tissues. Genes associated with lymph node metastasis were identified by means of the supervised learning technique. Differentially expressed genes (77 up-regulated and 45 down-regulated genes) were identified in more than 75 percent of the tumors. The functional categories of these genes belonged to signal transduction (19 percent), metabolism (17 percent), cell structure/motility (14 percent), cell cycle (13 percent), and gene protein expression (13 percent). The gene expression pattern of reverse transcriptase polymerase chain reaction (RT-PCR) results from randomly selected genes shows a pattern similar to that of cDNA microarray. Moreover, the gene expression patterns observed were similar to those reported previously, suggesting rare racial differences. Sixty genes possibly associated with lymph node metastasis in colorectal cancer were selected on the basis of clinicopathological data obtained by performing signal-to-noise calculations. "Leave-one-out" cross-validation testing correctly classified 10 of 12 patients (83.3 percent) as having colorectal cancer with lymph node metastasis vs. those without metastasis. These results provide not only a new molecular basis for understanding the biologic properties of colorectal cancer, including lymph node metastasis, but also provide a resource for future development of therapeutic targets and diagnostic markers for colorectal cancer.

    To compare the differences of anatomical and histological characteristics of lymph nodes between BALB/c nude mice and BALB/c mice. Firstly, twenty BALB/c nude mice and twenty BALB/c mice were dissected by using a surgical microscope. Secondly, the differences of T cells and B cells at the lymph node were compared by the expressions of CD 3 and CD 20 immunohistochemistry dyes. There were, on average, 23 nodes per mouse contained within the large lymph node assembly in the BALB/c nude mouse. The anatomical features of the lymph node distribution in the nude mice were mainly found in the neck with relatively higher density. There were two lymph nodes both in the submandible lymph nodes group and in the superficial cervical lymph nodes group (the constituent ratios were 95% and 90%, respectively) in the BALB/c nude mice, but there were four lymph nodes (the constituent ratios were 95% and 90%, respectively) in the BALB/c mice. There were significant difference between the BALB/c nude mice and the BALB/c mice. Mostly there were two lymph nodes of deep cervical lymph nodes both in the BALB/c nude mice and the BALB/c mice (the constituent ratios were 95% and 100%, respectively). There were no significant difference between the BALB/c nude mice and the BALB/c mice. We confirmed that the number of CD 3 -positive T lymphocytes in lymph nodes of the nude mice decreased greatly as compared with the BALB/c mice. Expressions of CD3 in T cells were 95% and 100% in the BALB/c nude mice and in the BALB/c mice, respectively. There were significant differences between the BALB/c nude mice and the BALB/c mice. Expressions of CD20 in B cells were 95% and 100% in the BALB/c nude mice and in the BALB/c mice, respectively. There was no significant difference between the BALB/c nude mice and BALB/c mice. The anatomical pictures of lymph node distribution in the nude mouse will be benefit to those who are interested. The anatomical features of the lymph node local higher density in neck of

    Melanoma preferentially spreads via lymph nodes. Melanoma exosomes can induce angiogenesis and immune suppression. However, a role for melanoma exosomes in facilitating tumor tolerance in lymph nodes has not been considered. Herein, the hypothesis that melanoma exosome mediated induction of vascular endothelial cell (VEC) derived tumor necrosis factor alpha (TNF-α) results in lymphatic endothelial cell (LEC) mediated tumor tolerance is explored. To support this hypothesis, experiments involving ex vivo lymph node associated VECs, LECs, dendritic cells and T lymphocytes are proposed based upon a previously established fluorescent exosome lymph node trafficking model. The implication of the hypothesis in the context of melanoma exosome mediated induction of tumor tolerance in lymph nodes is then discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To analyse the epidemiological, diagnostic and therapeutic aspects of cervical lymph node tuberculosis (TB) in Libreville. This retrospective descriptive multicentre study included all 140 patients with complete files who were treated for cervical lymph node TB from 2001 through 2006, regardless of whether TB was found at any other site. A slight predominance of men was observed. The infected lymph nodes were most often located at the posterior triangle of the neck. Histological proof was obtained for 81 patients. We recorded 94 cures, 4 cases of therapeutic failure, 34 patients lost to follow-up and 8 deaths. Cervical lymph node tuberculosis is a common ailment. Excisional lymph node biopsy has a twofold interest -therapeutic and diagnostic. It is based on histological examination, which must henceforth be systematic. Tuberculosis is a major HIV-related opportunistic infection and must be screened for or monitored at every HIV check-up.

    Purpose: To assess the safety and potential equivalence of the use of hemosiderin compared to the Technetium-99 in sentinel lymph node biopsy in human breast cancer. Methods: Non-random sample of 14 volunteer women diagnosed with breast cancer with primary tumors (T1/T2) and clinically tumor-free axilla were submitted to the identification of sentinel lymph node using hemosiderin obtained from autologous blood injected in the periareolar region 24h before surgery on an outpatient basis. Patients received preoperative subareolar intradermal injection of Technetium-99 in the immediate preoperative period. Patients were submitted to sentinel lymph node biopsy, with incision in the axillary fold guided by Gamma-Probe, dissection by planes until the identification of the point of maximum uptake of Technetium-99, identifying the marked nodes and their colors. All surgical specimens were sent for pathological and immunohistochemical study. Results: The results showed no evidence of side effects and/or allergic and non-allergic reactions in patients submitted to SLNB with hemosiderin. The SLN identification rate per patient was 100%. SLNB identification rate per patient with hemosiderin was the same as that of Technetium, with a concordance rate of 100% between the methods. Conclusion: Hemosiderin is a safe dye that is equivalent to Technetium in breast sentinel lymph node biopsy. (author)

    Considering the advantages and disadvantages of lateral lymph node dissection in patients with advanced lower rectal cancer, it would be ideal to select candidates for lateral lymph node dissection by preoperative imaging study including magnetic resonance imaging (MRI). We have reported that the cut-off value of minimal diameter of lateral lymph node could be set at 6 mm for indication of lateral lymph node dissection. In the present study, we evaluated whether it would be appropriate to apply the cut-off value of minimal diameter of lateral lymph node in MRI. Forty-four patients with advanced lower rectal cancer underwent a curative surgery with lateral lymph node dissection or sampling from 1997 to 2009 in our institute. Among them, 25 patients received MRI preoperatively and analyzed. The images were obtained by a sagittal method that was diagonal along sacro-iliac joint with 5 mm thick sections. Lateral lymph node metastasis was detected in 5 cases, one side in 4 cases and both sides in 1 case. The sensitivity, specificity, positive predict value, and accuracy for predicting metastasis was 50%, 90%, 42.9% and 84.8% respectively, when the cut-off value of the minimal diameter was set at 6 mm in MRI. Our results indicated that a 6 mm set as the cut-off value of minimal diameter of lateral lymph node was suitable for the prediction of lateral lymph node metastasis since the accuracy was relatively high (84.8%), though it was hardly to detect metastatic lymph node less than 6 mm.

    Purpose: To evaluate the incidence and prognostic significance of lymph node metastasis in maxillary sinus carcinoma. Methods and Materials: We reviewed the records of 97 patients treated for maxillary sinus carcinoma with radiotherapy at Stanford University and at the University of California, San Francisco between 1959 and 1996. Fifty-eight patients had squamous cell carcinoma (SCC), 4 had adenocarcinoma (ADE), 16 had undifferentiated carcinoma (UC), and 19 had adenoid cystic carcinoma (AC). Eight patients had T2, 36 had T3, and 53 had T4 tumors according to the 1997 AJCC staging system. Eleven patients had nodal involvement at diagnosis: 9 with SCC, 1 with UC, and 1 with AC. The most common sites of nodal involvement were ipsilateral level 1 and 2 lymph nodes. Thirty-six patients were treated with definitive radiotherapy alone, and 61 received a combination of surgical and radiation treatment. Thirty-six patients had neck irradiation, 25 of whom received elective neck irradiation (ENI) for N0 necks. The median follow-up for alive patients was 78 months. Results: The median survival for all patients was 22 months (range: 2.4-356 months). The 5- and 10-year actuarial survivals were 34% and 31%, respectively. Ten patients relapsed in the neck, with a 5-year actuarial risk of nodal relapse of 12%. The 5-year risk of neck relapse was 14% for SCC, 25% for ADE, and 7% for both UC and ACC. The overall risk of nodal involvement at either diagnosis or on follow-up was 28% for SCC, 25% for ADE, 12% for UC, and 10% for AC. All patients with nodal involvement had T3-4, and none had T2 tumors. ENI effectively prevented nodal relapse in patients with SCC and N0 neck; the 5-year actuarial risk of nodal relapse was 20% for patients without ENI and 0% for those with elective neck therapy. There was no correlation between neck relapse and primary tumor control or tumor extension into areas containing a rich lymphatic network. The most common sites of nodal relapse were in the

    We studied and analyzed therapeutic outcomes of a radical surgery under local anesthesia for breast cancer in our department. Subjects were 53 patients with breast cancer whose diagnoses were definitely made before surgery. Indications were: localized ductal carcinoma in situ (DCIS) diagnosed preoperatively; invasive carcinoma less than 3 cm in tumor diameter on ultrasound and magnetic resonance imaging scan; and clinically tumors with negative axillary lymph nodes. Operative procedures included microdochectomy or lumpectomy associated with sentinel lymph node navigation biopsy (SLNB). We could perform the operation under local anesthesia in all the 53 patients, and were not demanded to shift from local to general anesthesia. Surgical stumps were positive in 10 patients (18.9%). Of the ten patients, additional resection was performed in one, and irradiation was added to the remaining nine patients. SLNB was performed in a total of 39 patients, six (15.4%) patients of them had metastasis and two out of the six patients underwent additional axillary lymph node dissection. None of serious complications were encountered. Local recurrence and hepatic metastasis occurred in each one patient in an averaged observation period of 15.1 months. This day's radical operation under local anesthesia for breast cancer is a useful procedure as minimally invasive surgery as for the indications employed in this study. (author)

    Aim: aim of this study is to magnify the lymphoscintigraphy examination by gamma probe with SPECT acquisition for very accurate detection of depth of axilla node in patients affected by melanoma. Methods: according to physiological peculiarities the lymphatic system plays a very important role and represents the most important barrier to neoplastic cells spreading. The 'sentinel node' is the first lymph node draining the affected area. The tendency for surgery is a 'preventive' axillary dissection, even in presence of a clinically negative examination. In fact a high percentage of clinically negative lymph node shows a positive histology (presence of metastatic cells). The nuclear medicine method for researching 'sentinel node' is represented by a regional lymphoscintigraphy with normal gamma camera with a large field of view followed by examination with gamma detecting probe and, in following day, controlled in operating room to confirm the presence of the node early identified. We have completed this protocol with SPECT examination of affected axilla by use of injected laboratory capillary around axilla to perform an exact investigation of node depth. Discussion: Our experience in 150 cases in 18 months shows 100% of axilla 'sentinel node' detection, 25 cases with positive histologic examination and subsequently axillary dissection. Conclusions: In conclusion the scintigraphic examination with lymphoscintigraphy represents a good tool for management of patient with melanoma and the use of ''targeting' with collimated SPECT represent a very aid for the surgeon in reduction time for detection and dissection of lymph node, with high reduction of anesthesia duration

    The aim of this study was to review the feasibility of selective sentinel lymph node biopsy in patients with previous surgery for breast cancer, as well as to examine the factors that may interfere with sentinel node detection. A retrospective review was performed on 91 patients with breast cancer and previous breast surgery, and who underwent sentinel lymph node biopsy. Patients were divided into two groups according to their previous treatment: aesthetic breast surgery in 30 patients (group I) and breast-conserving surgery in 61 (group II). Lymphoscintigraphy was performed after an intra-tumour injection in 21 cases and a peri-areolar injection in 70 cases. An analysis was made of lymphatic drainage patterns and overall sentinel node detection according to clinical, pathological and surgical variables. The overall detection of the sentinel lymph node in the lymphoscintigraphy was 92.3%, with 7.7% of extra-axillary drainages. The identification rate was similar after aesthetic breast surgery (93.3%) and breast-conserving surgery (91.8%). Sentinel lymph nodes were found in the contralateral axilla in two patients (2.2%), and they were included in the histopathology study. The non-identification rate in the lymphoscintigraphy was 7.7%. There was a significantly higher non-detection rate in the highest histological grade tumours (28.6% grade III, 4.5% grade I and 3.6% grade II). Sentinel lymph node biopsy in patients with previous breast surgery is feasible and deserves further studies to assess the influence of different aspects in sentinel node detection in this clinical scenario. A high histological grade was significantly associated with a lower detection. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

    Lymphadenectomy is recommended during surgery for papillary thyroid carcinoma when there is evidence of cervical lymph node metastasis (therapeutic) or in high-risk patients (prophylactic) such as those with T3 and T4 tumors of the TNM classification. Selective sentinel lymph node biopsy may improve preoperative diagnosis of nodal metastases. To analyze the results of selective sentinel lymph node biopsy in a group of patients with papillary thyroid carcinoma and no evidence of nodal involvement before surgery. A retrospective, single-center study in patients with papillary thyroid carcinoma and no clinical evidence of lymph node involvement who underwent surgery between 2011 and 2013. The sentinel node was identified by scintigraphy. When the sentinel node was positive, the affected compartment was removed, and when sentinel node was negative, central lymph node dissection was performed. Forty-three patients, 34 females, with a mean age of 52.3 (±17) years, were enrolled. Forty-six (27%) of the 170 SNs resected from 24 (55.8%) patients were positive for metastasis. In addition, 94 (15.6%) out of the 612 lymph nodes removed in the lymphadenectomies were positive for metastases. Twelve of the 30 (40%) low risk patients (cT1N0 and cT2N0) changed their stage to pN1, whereas 12 of 13 (92%) high risk patients (cT3N0 and cT4N0) changed to pN1 stage. Selective sentinel lymph node biopsy changes the stage of more than 50% of patients from cN0 to pN1. This confirms the need for lymph node resection in T3 and T4 tumors, but reveals the presence of lymph node metastases in 40% of T1-T2 tumors. Copyright © 2017 SEEN.

    Full Text Available Abstract Introduction: melanoma is a very aggressive cancer, with increasing incidence, and is currently the fifth most common cancer in men and the sixth most common in women in the United States. Melanoma is not unusual in pregnancy, with an estimated occur-rence rate of 1:1.000. Although not the most common cancer in pregnancy, melanoma is the tumor with the highest incidence ofplacenta and fetus metastases. Description: a 29-year-old lady, 4 weeks after conception underwent resection of an atypical pigmented lesion after a diagnosis of stage T4b melanoma. At 16 weeks she underwent a broad local excision and sentinel lymph node (SLN biopsy. SLN was evaluated histologically and tested positive for melanoma. A radical axillary lymphadenectomy was performed on the patient without evidence of metas-tasis in any other LN. In the 40th week of pregnancy, labor was induced and a healthy newborn was deli-vered via cesarean. Discussion: melanoma management in pregnancy is more complex and requires multidisciplinary coor-dination, as well as extensive discussion with the patient and her family. We present a case report description in which treatment recommendations are established according to no pregnancy experience.

    We wanted to evaluate the value of a lymph node specific MR contrast agent, Gadofluorine M, for the differentiation of hyperplastic and metastatic lymph nodes. This study included thirty-one rabbits. In ten rabbits, an injection of egg yolk or feces of rat into the calf muscles induced hyperplasia of the lymph node. In sixteen rabbits, metastasis of the lymph node was induced by implantation of VX2 tumor. Five rabbits were normal control models. We acquired the T1-, T2-weighted and SPGR coronal imaging before enhancement with 1.5 T MR. After injection of Gadofluorine M (5 {mu}mol/mL, total amount: 4 mL) interstitially into the interdigital skin fold of the hind limb, we acquired the SPGR coronal imaging at 15, 30, 60 and 90 minutes. We calculated the signal-to-noise ratios on the sequential images, and we recorded the number, size and location of the popliteal and iliac lymph nodes. Three readers assessed the state of the lymph nodes according to the pattern of enhancement: they were deemed hyperplastic nodes when totally enhanced and as metastatic nodes when there was no or partial enhancement. We also compared the imaging patterns with the histopathological results. Among the 26 hyperplasia- or metastasis-induced rabbits, two rabbits were excluded because of failure to be enhanced. Histopathologic evaluation of the 24 rabbits detected one hundred seventeen lymph nodes: forty-six lymph nodes in nine hyperplasia-induced rabbits and seventy-one (metastasis in twenty-eight) lymph nodes in fifteen metastasis-induced rabbits. Out of one hundred two lymph nodes that were larger than 5 mm in size, MR enabled us to detect one hundred one lymph nodes (99.1%). The means of sensitivity, specificity, and the positive and negative predictive values for the diagnosis of lymph node metastasis by three readers were 97.6% (82/84), 98.2% (215/219), and 95.3% (82/86), and 99.1% (215/217), respectively ({rho} < 0.05). Interstitial MR lymphography using Gadofluorine M showed excellent

    Quantification of microvessels in tumors is mostly based on counts of vessel profiles in tumor hot spots. Drawbacks of this method include low reproducibility and large interobserver variance, mainly as a result of individual differences in sampling of image fields for analysis. Our aim was to test an unbiased method for quantifying microvessels in healthy and tumorous lymph nodes of dogs. The endothelium of blood vessels was detected in paraffin sections by a combination of immunohistochemistry (von Willebrand factor) and lectin histochemistry (wheat germ agglutinin) in comparison with detection of basal laminae by laminin immunohistochemistry or silver impregnation. Systematic uniform random sampling of 50 image fields was performed during photo-documentation. An unbiased counting frame (area 113,600 microm(2)) was applied to each micrograph. The total area sampled from each node was 5.68 mm(2). Vessel profiles were counted according to stereological counting rules. Inter- and intraobserver variabilities were tested. The application of systematic uniform random sampling was compared with the counting of vessel profiles in hot spots. The unbiased estimate of the number of vessel profiles per unit area ranged from 100.5 +/- 44.0/mm(2) to 442.6 +/- 102.5/mm(2) in contrast to 264 +/- 72.2/mm(2) to 771.0 +/- 108.2/mm(2) in hot spots. The advantage of using systematic uniform random sampling is its reproducibility, with reasonable interobserver and low intraobserver variance. This method also allows for the possibility of using archival material, because staining quality is not limiting as it is for image analysis, and artifacts can easily be excluded. However, this method is comparatively time-consuming. (c) 2008 Wiley-Liss, Inc.

    Axillary nodal status is the most significant prognosticator for predicting survival and guiding adjuvant therapy in breast cancer patients. Sentinel lymph node biopsy (SLNB) represents a minimally invasive procedure with low morbidity for staging axillary nodal status. In this article we review and report our experiences in patients with early breast cancer who underwent SLNB at the Revlon/UCLA Breast Center. Between September 1998 and May 2000, a total 83 SLNBs were performed in 81 patients with proven breast cancer and negative axillary examination who elected to have SLNB as the first step of nodal staging. Two patients had bilateral breast cancer. SLNB was localized by using both 99Tc sulfur colloid (83 cases) and isosulfan blue dye (75 cases). Data of these patients were prospectively collected and analyzed. The clinical and pathologic characteristics of women with positive and negative sentinel lymph nodes (SLNs) were compared to identify features predictive of SLN metastasis. Of the 83 cases, the SLN was successfully localized in 82 (98.8%). Sixty-three percent of patients had SLNs found in level I only, 18.3% in both level I and II, and 4.9% in level II alone. The vast majority (84.3%) of these cases had T1 breast cancer with an average size of 1.55 cm for the entire series. Twenty-three patients (28%) had positive SLNs, with an average of 1.5 positive SLNs per patient. Fifteen had metastases detected by hematoxylin and eosin staining and 8 had micrometastases detected by immunohistochemistry (IHC) using anticytokeratin antibodies. Ten of the former group agreed to and 2 of the latter group opted for full axillary lymph node dissection (ALND). An average of 17.5 lymph nodes were removed from each ALND procedure. Additional metastases or micrometastases were found in seven patients (in a total of 28 lymph nodes). Three patients with completely negative SLNs experienced additional axillary lymph node removal due to their election of free flap reconstruction

    To study which variables involved in the process of selective sentinel node biopsy (SSNB) influence the intraoperative detection of the sentinel lymph node. This was a prospective cross-sectional study in 210 patients (mean age, 54 years) diagnosed with breast cancer who underwent SSNB. We recorded clinical, radiological, radioisotope administration, surgical, and histological data as well as follow-up data. We did a descriptive analysis of the data and an associative analysis using multivariable regression. Deep injection alone was the most common route of radioisotope administration (72.7%). Most lesions were palpable (57.1%), presented as nodules (67.1%), measured less than 2 cm in diameter (64.8%), were located in the upper outer quadrant (49.1%), were ductal carcinomas (85.7%), were accompanied by infiltration (66.2%), and had a histologic grade of differentiation of ii (44.8%). Preoperative scintigraphy detected the sentinel node in 97.6% of cases and 95.7% were detected during the operation. One axillary relapse was observed. In the associative study, the variables "preoperative lymphoscintigraphy" and "histologic grade of differentiation of the tumor" were significantly associated with the detection of the sentinel lymph node during the operation. The probability of not detecting the sentinel lymph node during the surgical intervention is higher in patients with high histologic grade tumors or in patients in whom preoperative lymphoscintigraphy failed to detect the sentinel node.

    Lymph node (LN) hypertrophy, the increased cellularity of LNs, is the major indication of the initiation and expansion of the immune response against infection, vaccination, cancer or autoimmunity. The mechanisms underlying LN hypertrophy remain poorly defined. Here, we demonstrate that LIGHT (TNFSF14) is a novel factor essential for LN hypertrophy after CFA immunization. Mechanistically, LIGHT is required for the influx of lymphocytes into but not egress out of LNs. In addition, LIGHT is required for DC migration from the skin to draining LNs. Compared with WT mice, LIGHT−/− mice express lower levels of chemokines in skin and addressins in LN vascular endothelial cells after CFA immunization. We unexpectedly observed that LIGHT from radioresistant rather than radiosensitive cells, likely Langerhans cells, is required for LN hypertrophy. Importantly, antigen-specific T cell responses were impaired in DLN of LIGHT−/− mice, suggesting the importance of LIGHT regulation of LN hypertrophy in the generation of an adaptive immune response. Collectively, our data reveal a novel cellular and molecular mechanism for the regulation of LN hypertrophy and its potential impact on the generation of an optimal adaptive immune response.

    An analysis of the scientific data was made. It was used the literature devoted to the intraoperative visualization of the sentinel lymph nodes in patients with lung cancer. Correct detection of such lymph nodes with following pathologic investigation allowed limiting the volume of lympho-dissection in a number of patients. There is the possibility of maximal in-depth study of the sentinel lymph nodes by purposeful application of most sensible pathologic and molecular methods for detection their micrometastatic lesions. At the same time the treatment strategy and prognosis could be determined. The authors present the results of an application of dye techniques, radioactive preparation and fluorescence imaging for sentinel lymph node detection. Advantages and disadvantages of the methods are shown in the article. There are validated the prospects of technical development, study of information value of new applications and the most perspective method of fluorescence indocyanine green visualization by lymph outflow.

    To analyze patterns of failure in malignant melanoma patients with lymph node involvement who underwent complete lymph node dissection (LND) of the nodal basin. To determine prognostic factors predictive of local recurrence in the lymph node basin in order to select patients who may benefit from adjuvant radiotherapy. A retrospective analysis of 338 patients undergoing complete LND for melanoma between 1970 and 1996 who had pathologically involved lymph nodes was performed. Mean follow-up from the time of LND was 54 months (range: 12-306 months). Lymph node basins dissected included the neck (56 patients), axilla (160 patients), and groin (122 patients). Two hundred fifty-three patients (75%) underwent therapeutic LND for clinically involved nodes, while 85 patients (25%) had elective dissections. Forty-four percent of patients received adjuvant systemic therapy. No patients received adjuvant radiotherapy to the lymph node basin. Overall and disease-specific survival for all patients at 10 years was 30% and 36%, respectively. Overall nodal basin recurrence was 30% at 10 years. Mean time to nodal basin recurrence was 12 months (range: 2-78 months). Site of nodal involvement was prognostic with 43%, 28%, and 23% nodal basin recurrence at 10 years with cervical, axillary, and inguinal involvement, respectively (p = 0.008). Extracapsular extension (ECE) led to a 10-year nodal basin failure rate of 63% vs. 23% without ECE (p basin at 10 years, compared to 16% for patients found to have involved nodes after elective dissection (p = 0.002). Lymph nodes larger than 6 cm led to a failure rate of 80% compared to 42% for nodes 3-6 cm and 24% for nodes less than 3 cm (p basin failure with 25%, 46%, and 63% failure rates at 10 years for 1-3, 4-10, and > 10 nodes involved (p = 0.0001). There was no significant difference in nodal basin control in patients with synchronous or metachronous lymph node metastases, nor in patients receiving or not receiving adjuvant systemic therapy

    Neutrophil-lymphocyte ratio (NLR) and BMI were examined as pre-operative predictors for lymph node metastases in patients with low-risk endometrial cancer. The study was a retrospective analysis of 534 endometrial cancer patients that underwent hysterectomy and lymph node dissection. Included subjects had a preoperative diagnosis of a grade 1 or 2 endometrioid carcinoma and no macroscopic extrauterine disease. We compared node-negative to node-positive patients to identify correlates of node-positive disease. The node-positive group presented with lower BMI than the node-negative group, 31.5 and 34.4, respectively (p = .03). The mean NLR was higher in the node-positive group 3.4 vs 2.9 (p = .08), showing a trend towards significance on univariate analysis. On multivariate analysis, lower BMI was found to be an independent predictor for nodal metastasis. Our data suggest that lower BMI is a risk factor for lymph nodes involvement in low-risk endometrial cancer. Impact statement Most endometrial cancer patients have low-risk disease with low risk for lymph nodes metastasis. In order to reduce the number of patients that will undergo unnecessary lymph node dissection, different types of preoperative predictors for lymph node involvement were studied. CA 125 and different imaging modalities were found as useful predictors for more advanced disease. Less studied predictors are the systemic inflammatory response markers and patient's BMI. This study suggests that lower BMI is a risk factor for lymph node involvement in low-risk endometrial cancer. The neutrophil to lymphocyte ratio was close to significance as a predictor for lymph node involvement. In practice, physicians might favour comprehensive lymph node dissection when there is a doubt regarding the procedure but the patient is lean. The study's conclusion can be utilised for triaging patients to general gynaecologist vs gynaecologic oncologist. Further research should focus on combining predictors such as

    Full Text Available Cancer of unknown primary (CUP is the finding of a metastatic cancerous lesion without an established primary source localized within the body. CUP can be of any cancer cell type, however, adenocarcinoma is most often identified by histology. Up to 5% of all malignant diagnoses are classified as CUP. PET is an imaging modality often utilized to distinguish a primary source in the setting of CUP, yet often a primary is never identified. CUP can be further stratified using specific qualifiers as favorable and unfavorable, indicating the potential therapeutic response to treatment regimens. Treatment approach to CUP relies heavily on the cell type identified by histology, the location of the lesion, and the amount of spread within the body. In the typical setting and presentation, per current literature, CUP arises in the 7th decade of life in patients with multiple comorbidities, and often has a poor prognostic value. This case report identifies an atypical presentation of CUP, a 38-year-old Caucasian female with an axillary mobile mass, and no associated systemic symptoms. Biopsy of the node and immunohistochemical staining showed histology consistent with metastatic carcinoma. Mammography, MRI, and PET scan found no evidence of tumor primary or distant metastasis. Further staining confirmed metastatic carcinoma consistent with breast origin, without an established breast primary. As in this case, CUP may present in an atypical manner, warranting a thorough investigation aiming to identify the tumor primary to aid in identification of a proper treatment regimen and approach.

    The aim of our study was to investigate the occurrence of fluorodeoxyglucose (FDG) avidity in draining axillary lymph nodes after vaccination against influenza (H1N1v pandemic and seasonal) and to determine the period of increased FDG uptake. During December 2009, patients referred for 18 F-FDG positron emission tomography (PET)/CT scans (n = 293) filled in a questionnaire concerning vaccination type (seasonal and/or H1N1v), time and anatomical localization of vaccination. Only injections in deltoid regions were evaluated, thus ensuring that draining lymph nodes were axillary. If more vaccinations had been given, only the latest vaccination was evaluated in each deltoid region. Of all patients who underwent PET/CT scans during December 2009, 26% had been vaccinated with at least one influenza vaccination in the deltoid region. A total of 92 'draining' and 60 'reference' (i.e. contralateral, non-vaccinated) axillary lymph nodes were evaluated in 61 patients (19 of 61 patients were scanned twice). The maximal intensity in FDG uptake (SUV max ) in draining lymph nodes was 5 g/ml body weight (BW), whereas the maximal intensity in reference lymph nodes was 1.9 g/ml BW. The SUV max was normalized approximately 40 days after vaccination. No significant enlargement of metabolically active draining lymph nodes could be demonstrated on CT scan. Chemotherapy or immunosuppressive drugs given within 2 weeks from vaccination did not affect SUV max in the axillary lymph nodes. Influenza vaccination may lead to FDG-avid draining lymph nodes beyond 1 month. (orig.)

    Although the role of an axillary lymph node dissection for the primary breast cancer is considered to be a prognostic indicator, regarding the determination of the treatment strategy after surgery, and the best modality for regional control, this procedure is harmful rather than ineffective in cases with a histologically negative node. The sentinel lymph node (SLN) biopsy is a procedure used to assess the degree of nodal involvement before and/or during surgery. From June, 1999 to January, 2002, we performed an SLN biopsy for 47 primary breast cancer patients (T1-2N0-1M0) using either a dye or combined (dye and gamma probe guided) method with a back up conventional axillary node dissection at the Second Department of Surgery, Fukuoka University School of Medicine. The dye method was performed on 39 patients, and it resulted in the accurate identification of the SLN in 74.4% of patients, compared with 94.7% in latter series of 19 patients. In addition, the dye method demonstrated a sensitivity of 66.6%, a specificity of 100% and an accuracy of 96.6%. Eight patients received the combined method, and the SLN was identified in 100% of these patients. This combined method showed a sensitivity of 80%, a specificity of 100% and an accuracy of 87.5%. On the other hand an intraoperative examination using frozen sections resulted in a sensitivity of 50%, a specificity of 100% and an accuracy in the diagnosis of 83.3%. These data suggest that an SLN biopsy for early breast cancer (T1N0) can be performed to eliminate any unnecessary axillary node dissection in cases with negative SLN. However, the successful results of this method depend on the cooperation of the multidisciplinary team (surgeons, pathologists and nuclear radiologists) and the informed consent of all patients.

    The role of immune surveillance in controlling the spread of breast cancer to the regional nodes is poorly understood. In theory regional nodal irradiation (RNI) might compromise this host function. However the clinical evidence suggests that the risk of regional recurrence is lower in patients with early breast cancer whose axilla has been irradiated compared to no axillary treatment. The role of RNI after breast conserving surgery has not been well studied. A policy of level III clearance and only irradiating the axilla for residual disease and a selective policy of axillary irradiation in node positive patients after sentinel node biopsy or lower axillary node sample is recommended. Irradiation of the medial supraclavicular fossa after axillary dissection is suggested where there are four or more nodes involved on axillary dissection. There is little data to inform selection of patients for RNI after neoadjuvant systemic therapy. The role of postmastectomy radiotherapy (PMRT) was largely established on the basis of comprehensive RNI. It is unclear whether irradiating less than the chest wall and peripheral lymphatics confers the same level of benefit. The role of PMRT in women with 1-3 involved nodes remains controversial and investigational. Biological factors such as oestrogen and progesterone receptor status and HER-2 protein expression may play a role in determining benefits from PMRT. The role of internal mammary nodal irradiation is unclear. The individualisation of RNI based on molecular and genetic factors should be a priority for research. The benefits of RNI need to be carefully balanced against the risks of cardiotoxicity, pneumonitis, lymphoedema, brachial plexopathy and secondary malignancy.

    Background: Lymph node status is a major determinant of stage and survival in patients with lung cancer; however, little information is available about the expected yield of a mediastinal lymphadenectomy. Methods: The American College of Surgeons Oncology Group Z0030 prospective, randomized trial of mediastinal lymph node sampling vs complete mediastinal lymphadenectomy during pulmonary resection enrolled 1,111 patients from July 1999 to February 2004. Data from 524 patients who underwent complete mediastinal lymph node dissection were analyzed to determine the number of lymph nodes obtained. Results: The median number of additional lymph nodes harvested from a mediastinal lymphadenectomy following systematic sampling was 18 with a range of one to 72 for right-sided tumors, and 18 with a range of four to 69 for left-sided tumors. The median number of N2 nodes harvested was 11 on the right and 12 on the left. A median of at least six nodes was harvested from at least three stations in 99% of patients, and 90% of patients had at least 10 nodes harvested from three stations. Overall, 21 patients (4%) were found to have occult N2 disease. Conclusions: Although high variability exists in the actual number of lymph nodes obtained from various nodal stations, complete mediastinal lymphadenectomy removes one or more lymph nodes from all mediastinal stations. Adequate mediastinal lymphadenectomy should include stations 2R, 4R, 7, 8, and 9 for right-sided cancers and stations 4L, 5, 6, 7, 8, and 9 for left-sided cancers. Six or more nodes were resected in 99% of patients in this study. Trial registry: ClinicalTrials.gov; No.: NCT00003831; URL: clinicaltrials.gov PMID:20829340

    Background. Previous studies of CT enhancement of lymphomatous lymph nodes (LLN) of the neck showed that the LLN had lower enhancement values than normal lymph nodes. Purpose. To elucidate the contrast medium enhancement curves of LLN in the mediastinum by comparing the curves of LLN with those of normal lymph nodes, and to compare the present enhancement curves of LLN of the mediastinum with the curves of LLN of the neck from a previous similar investigation. Material and Methods. Twenty-four consecutive patients with LLN in the mediastinum (9 with Hodgkin's lymphoma [HL]) and 23 control patients with sarcomas and thus presumably normal mediastinal nodes underwent dynamic CT examinations. The previous, similar investigation of lymph nodes of the neck comprised 28 patients with LLN and 20 control patients. Results. The enhancement curves of the mediastinal LLN had significantly lower values than those of the mediastinal control nodes. The LLN of the mediastinum had lower mean peak contrast values than the corresponding nodes of the neck from a previous investigation. Conclusion. The comparison of enhancement curves of mediastinal LLN with mediastinal control nodes showed a marked similarity with and substantiates our previous findings in lymph nodes of the neck

    Previous studies of CT enhancement of lymphomatous lymph nodes (LLN) of the neck showed that the LLN had lower enhancement values than normal lymph nodes. To elucidate the contrast medium enhancement curves of LLN in the mediastinum by comparing the curves of LLN with those of normal lymph nodes, and to compare the present enhancement curves of LLN of the mediastinum with the curves of LLN of the neck from a previous similar investigation. Twenty-four consecutive patients with LLN in the mediastinum (9 with Hodgkin's lymphoma [HL]) and 23 control patients with sarcomas and thus presumably normal mediastinal nodes underwent dynamic CT examinations. The previous, similar investigation of lymph nodes of the neck comprised 28 patients with LLN and 20 control patients. The enhancement curves of the mediastinal LLN had significantly lower values than those of the mediastinal control nodes. The LLN of the mediastinum had lower mean peak contrast values than the corresponding nodes of the neck from a previous investigation. The comparison of enhancement curves of mediastinal LLN with mediastinal control nodes showed a marked similarity with and substantiates our previous findings in lymph nodes of the neck.

    Complete mesocolic excision (CME) is nowadays state of the art in the treatment of colon cancer. In cases of carcinoma of transverse colon and of both flexures an extramesocolic lymph node metastasis can be found in the infrapancreatic lymph node region (ILR) and across the gastroepiploic arcade (GLR). These direct metastatic routes were not previously systematically considered. In order to validate our hypothesis of these direct metastatic pathways and to obtain evidence of our approach of including dissection of these areas as part of CME, we initiated a prospective study evaluating these lymph node regions during surgery. Forty-five consecutive patients with primary tumour manifestation in transverse colon and both flexures between May 2010 and January 2013 were prospectively analyzed. Patients were followed up for at least 6 months. Mode of surgery, histopathology, morbidity and mortality were evaluated. Twenty-six patients had a carcinoma of transverse colon, 16 patients one of hepatic flexure and four patients one of splenic flexure. The median lymph node yield was 40. Occurrence of lymph node metastasis in ILR was registered in five patients and in GLR in four patients. The mean lymph node ratio was 0.085. Postoperative complications occurred in nine patients, and postoperative mortality was 2 %. We were able to demonstrate this novel metastatic route of carcinomas of the transverse colon and of both flexures in ILR and GLR. These could be considered as regional lymph node regions and have to be included into surgery for cancer of the transverse colon including both flexures.

    Purpose: In many centers, supraclavicular fossa radiotherapy (SCF RT) is not routinely offered to breast cancer patients with one to three positive lymph nodes. We aimed to identify a subgroup of these patients who are at high risk of supra or infraclavicular fossa relapse (SCFR) such that they can be offered SCFRT at the time of diagnosis to improve long term locoregional control. Methods and Materials: We performed a retrospective analysis of the pathological features of 1,065 cases of invasive breast cancer with one to three positive axillary lymph nodes. Patients underwent radical breast conserving surgery or mastectomy. A total of 45% of patients received adjuvant chest wall/breast RT. No patients received adjuvant SCFRT. The primary outcome was SCFR. Secondary outcomes were chest wall/breast recurrence, distant metastasis, all death, and breast-cancer specific death. Kaplan-Meier estimates were used to calculate actuarial event rates and survival functions compared using log-rank tests. Multivariate analyses (MVA) of factors associated with outcome were conducted using Cox proportional hazards models. Results: Median follow-up was 9.7 years. SCFR rate was 9.2%. Median time from primary diagnosis to SCFR was 3.4 years (range, 0.7-14.4 years). SCFR was associated with significantly lower 10-year survival (18% vs. 65%; p < 0.001). Higher grade and number of positive lymph nodes were the most significant predictors of SCFR on MVA (p < 0.001). 10 year SCFR rates were less than 1% in all patients with Grade 1 cancers compared with 30% in those having Grade 3 cancers with three positive lymph nodes. Additional factors associated with SCFR on univariate analysis but not on MVA included larger nodal deposits (p = 0.002) and proportion of positive nodes (p = 0.003). Conclusions: Breast cancer patients with one to three positive lymph nodes have a heterogenous risk of SCFR. Patients with two to three positive axillary nodes and/or high-grade disease may warrant

    BACKGROUND: Sentinel lymph node biopsy, step sectioning and immunohistochemistry have changed detection of tumour deposits. Isolated tumour cells (ITC) are detected more frequently than earlier because of a changed level of detection. METHODS: A total of 108 sentinel lymph nodes from 30 patients...... with T1/T2 cN0 oral cancer were re-classified histologically to find possible ITC and to describe technical pitfalls. RESULTS: Primarily we found metastatic spread in 12 of 108 sentinel lymph nodes: five macrometastasis and seven micrometastasis. After re-classification, we found seven lymph nodes...... with macrometastasis, five with micrometastasis and two with ITC. CONCLUSION: The ITC are probably precursors of micrometastasis waiting to grow and should be treated as such. Benign inclusions and dendritic cells did not cause problems, but can mimic ITC....

    Spiral CT was performed before treatment in 35 patients with suspected cervical lymph node enlargement. By coronary and sagittal reconstruction it is possible to utilise the M/Q quotient which has become accepted as the result of sonographic and MRI examinations. It is now possible to obtain high diagnostic accuracy (97%) for distinguishing between reactive change from metastatic infiltration of lymph nodes (>8 mm) by using CT. Using spiral CT with 5 mm table movement, three patients diagnosed as stage N1 by axial CT were shown to be N2b. This represents a highly sensitive and highly specific method of lymph node diagnosis. Further diagnostic improvement derives from the ability to relate the lymph nodes to surrounding tissues. Spiral CT is also suitable for defining other space occupying lesions, e.g., the exact extent of retropharyngeal abscesses, abnormalities of the salivary glands or laryngocoeles. (orig.)

    Sentinel lymph node biopsy (SLNB) has emerged as an accurate, less invasive alternative to axillary lymph node dissection, and it has rapidly become the standard of care for patients with clinically node-negative breast cancer. The sentinel lymph node (SLN) hypothesis states that the pathological status of the axilla can be accurately predicted by determining the status of the first (i.e., sentinel) lymph nodes that drain from the primary tumor. Physicians use radio-labeled sulfur colloid and/or methylene blue dye to identify the SLN, which is most likely to contain metastatic cancer cells. However, the surgical procedure causes morbidity and associated expenses. To overcome these limitations, we developed a dual-modality photoacoustic and ultrasound imaging system to noninvasively detect SLNs based on the accumulation of methylene blue dye. Ultimately, we aim to guide percutaneous needle biopsies and provide a minimally invasive method for axillary staging of breast cancer. The system consists of a tunable dye laser pumped by a Nd:YAG laser, a commercial ultrasound imaging system (Philips iU22), and a multichannel data acquisition system which displays co-registered photoacoustic and ultrasound images in real-time. Our clinical results demonstrate that real-time photoacoustic imaging can provide sensitive and specific detection of methylene blue dye in vivo. While preliminary studies have shown that in vivo detection of SLNs by using co-registered photoacoustic and ultrasound imaging is feasible, further investigation is needed to demonstrate robust SLN detection.

    To evaluate and present our initial results of a new marker (hemosiderin) for mammary sentinel lymph node identification in an experimental model. Skins mapped like a lymphatic duct draining to the axilla in patients submitted to breast biopsy, in our mastology service, stimulated us to try it in an animal model (female dogs). Our theory was that some blood derivate (hemosiderin) was captured by macrophages and accessed the lymphatic ducts in direction to the axilla. Six female dogs of no defined race were studied. We injected 0,2 ml of technetium on both superior mammary glands. After ten minutes, a 2,5 ml solution of hemolized blood (hemosiderin) from the own animal was injected in the subareolar lymphatic plexus on the left superior mammary gland and 2,5 ml of patent blue concomitantly and equally on the contralateral gland. Ten minutes after, incisions on both axillae were made to search, through the lymphatic mapping and a gamma probe, the sentinel lymph nodes. Seven brown sentinel lymph nodes were identified and also radiomarked on the left axilla. Six blue sentinel lymph nodes were identified and also radiomarked on the right axilla. Preliminary studies of a potential new dye for sentinel lymph node identification are presented. It may be the change of the current use of the blue dyes and their severe side-effects on patients submitted to sentinel lymph node biopsies.

  17. Contribution of radioisotopic techniques to identify sentinel lymph-nodes (SLN) in breast cancer

    The SLN (one or several) is the first to receive lymph from a tumor. When a cancer cell comes off the tumor and circulates along the outgoing lymph, it meets a barrier, the SLN that intercepts and destroys it. If not, the cancer cell can stay and reproduce in the SLN making a metastasis which can affect other nodes in the same way. It has been shown that if the original tumor is small there is little chance that the SLN could be invaded and therefore little chance of dissemination to other lymph-nodes. Nowadays due to early detection, breast tumors are smaller than one cm, therefore with such size there is little chance of axillary lymph-nodes being affected. If it is confirmed by histological study that the SLN is free of metastasis, it is not necessary to perform a axillary emptying. This identification of SLNs has been achieved because of the advances of Radioisotopic Techniques, which has been carried out in our Hospital since 1997. We have been adapting this technique to the national supply of equipment and radio compounds always under a reliable and secure way. The aim of this presentation is to highlight the radioisotopic identification of SLNs in clinical investigation in 'Angel H. Roffo Institute', and its daily practice compare with Positron Emission Tomography (PET). By combining Radioisotopic Lymphography, Lymphochromography and intra surgical detection of the SN with Gamma Probe, we have obtained a true negative value of 95% of the SN, with 5% false negative. Due to this method we have included SN study in daily practice breast tumor patients with tumor up to 5 cm of diameter. Comparing this methods result (5% false negative), with the PET results, using 18 F-FDG, that has 33% false negatives, we conclude that a negative result can not replace this method of SN detection.

  18. Unusual metachronous isolated inguinal lymph node metastasis from adenocarcinoma of the sigmoid colon

    2011-10-01

    Full Text Available Abstract This study aimed to describe an unusual case of metachronous isolated inguinal lymph nodes metastasis from sigmoid carcinoma. A 62-year-old man was referred to our department because of an obstructing sigmoid carcinoma. Colonoscopy showed the obstructing lesion at 30 cm from the anal verge and abdominal CT revealed a sigmoid lesion infiltrating the left lateral abdominal wall. The patient underwent a colonic resection extended to the abdominal wall. Histology showed an adenocarcinoma of the colon infiltrating the abdominal wall with iuxtacolic nodal involvement. Thirty three months after surgery abdominal CT and PET scan revealed a metastatic left inguinal lymph node involvement. The metastatic lymph node was found strictly adherent to the left iliac-femoral artery and encompassing the origin of the left inferior epigastric artery. Histology showed a metachronous nodal metastasis from colonic adenocarcinoma. Despite metastastic involvement of inguinal lymph node from rectal cancer is a rare but well known clinical entity, to the best of our knowledge, this is the first report of inguinal metastasis from a carcinoma of the left colon. Literature review shows only three other similar reported cases: two cases of inguinal metastasis secondary to adenocarcinoma of the cecum and one case of axillary metastasis from left colonic carcinoma. A metastatic pathway through superficial abdominal wall lymphatic vessels could be possible through the route along the left inferior epigastric artery. The solitary inguinal nodal involvement from rectal carcinoma could have a more favorable prognosis. In the case of nodal metastasis to the body surface lymph nodes from colonic carcinoma, following the small number of such cases reported in the literature, no definitive conclusions can be drawn.

  19. Whole genome sequence analysis suggests intratumoral heterogeneity in dissemination of breast cancer to lymph nodes.

    Directory of Open Access Journals (Sweden)

    Full Text Available Intratumoral heterogeneity may help drive resistance to targeted therapies in cancer. In breast cancer, the presence of nodal metastases is a key indicator of poorer overall survival. The aim of this study was to identify somatic genetic alterations in early dissemination of breast cancer by whole genome next generation sequencing (NGS of a primary breast tumor, a matched locally-involved axillary lymph node and healthy normal DNA from blood.Whole genome NGS was performed on 12 µg (range 11.1-13.3 µg of DNA isolated from fresh-frozen primary breast tumor, axillary lymph node and peripheral blood following the DNA nanoball sequencing protocol. Single nucleotide variants, insertions, deletions, and substitutions were identified through a bioinformatic pipeline and compared to CIN25, a key set of genes associated with tumor metastasis.Whole genome sequencing revealed overlapping variants between the tumor and node, but also variants that were unique to each. Novel mutations unique to the node included those found in two CIN25 targets, TGIF2 and CCNB2, which are related to transcription cyclin activity and chromosomal stability, respectively, and a unique frameshift in PDS5B, which is required for accurate sister chromatid segregation during cell division. We also identified dominant clonal variants that progressed from tumor to node, including SNVs in TP53 and ARAP3, which mediates rearrangements to the cytoskeleton and cell shape, and an insertion in TOP2A, the expression of which is significantly associated with tumor proliferation and can segregate breast cancers by outcome.This case study provides preliminary evidence that primary tumor and early nodal metastasis have largely overlapping somatic genetic alterations. There were very few mutations unique to the involved node. However, significant conclusions regarding early dissemination needs analysis of a larger number of patient samples.

    Pathological examinations of lymph nodes (LN) in prostate cancer patients are handled differently at various institutions. The objective of this study is to provide means to improve the guidelines by examining the impact of step sectioning on LN status in patients with intermediate and high......-risk prostate cancer. Two hundred ten patients who awaited curative indented therapy were included. We first performed a standard pathological examination of the LN, followed by an extended pathological examination of the patients who were LN negative in the standard examination. The extended pathological...... indicate that an extended pathological examination of LN will improve the staging of intermediate- and high-risk prostate cancer patients; however, we acknowledge that it is both costly and time consuming. We do not recommend the use of cytokeratin staining in routine staining because...

  1. Prediction of nonsentinel lymph node metastasis in malignant melanoma.

    Sentinel lymph node biopsy (SLNB) is the standard at many institutions caring for melanoma patients. Patients with positive SLNB results are currently offered completion lymph node dissection (CLND) of the affected lymph node basin. This procedure entails considerable morbidity and is often applied to patients with shortened life expectancies. Because 80% of CLNDs yield no additional positive nodes and there is no proof that CLND leads to survival improvement, criteria are needed to limit this procedure to those most likely to harbor nonsentinel lymph node (SLN) metastases. A retrospective review of 349 cases of melanoma from January 1999 to April 2007 that underwent sentinel lymph node biopsy at a single institution was done. Statistical analysis was used to compare two subgroups of patients: a positive CLND group and a negative CLND group. These two groups were compared with regards to multiple variables related to patient demographics, primary tumor characteristics, and SLN tumor burden. Age and total size of SLN tumor deposit were the factors with the strongest correlation with CLND positivity. By applying a risk score model that uses the cutoff values of age 55 y and SLN tumor deposit of 5 mm, it is possible to predict CLND positivity in SLN-positive melanoma patients. The likelihood of CLND positivity in SLN-positive melanoma patients can be predicted from two criteria readily available: size of SLN tumor deposit and patient age.

    To use noninvasive fluorescence imaging to investigate the influence of molecular weight (MW) of proteins on the rate of loss from a subcutaneous (SC) injection site and subsequent uptake by the draining lymph nodes in mice. Bevacizumab (149 kDa), bovine serum albumin (BSA, 66 kDa), ovalbumin (44.3 kDa) or VEGF-C156S (23 kDa), labeled with the near infrared dye IRDye 680, were injected SC into the front footpad of SKH-1 mice. Whole body non-invasive fluorescence imaging was performed to quantitate the fluorescence signal at the injection site and in axillary lymph nodes. The half-life values, describing the times for 50% loss of proteins from the injection site, were 6.81 h for bevacizumab, 2.85 h for BSA, 1.57 h for ovalbumin and 0.31 h for VEGF-C156S. The corresponding axillary lymph node exposure, represented as the area of the % dose versus time curve, was 6.27, 5.13, 4.06 and 1.54% dose ∙ h, respectively. Our results indicate that the rate of loss of proteins from a SC injection site is inversely related to MW of proteins, while lymph node exposure is proportionally related to the MW of proteins in a mouse model.

    The aim of this study was to evaluate lymph node tuberculosis (LNT) cases in two provinces in Turkey with different demographic and socioeconomic characteristics. A total of 109 LNT cases were reviewed retrospectively. The cases were analyzed and compared for symptoms, findings, age, vaccination status, and diagnostic procedures. Socioeconomic conditions were also assessed for the two provinces. A palpable cervical node was considered a significant predictor for all LNT. Mediastinal lymph node involvement was found to be common in cases of pulmonary manifestation of LNT. Female patients were predominantly from the Van Province, while older patients were found to be from Izmir Province. LNT should be suspected in lymphadenitis patients of all age-groups especially in young adolescents with cervical lymph node enlargements. In the presence of mediastinal lymphadenopathy, pulmonary tuberculosis should be investigated.

    The authors present a procedure guideline for scintigraphic detection of sentinel lymph nodes in malignant melanoma and other skin tumours, in breast cancer, in head and neck cancer, and in prostate and penile carcinoma. Important goals of sentinel lymph node scintigraphy comprise reduction of the extent of surgery, lower postoperative morbidity and optimization of histopathological examination focussing on relevant lymph nodes. Sentinel lymph node scintigraphy itself does not diagnose tumorous lymph node involvement and is not indicated when lymph node metastases have been definitely diagnosed before sentinel lymph node scintigraphy. Procedures are compiled with the aim to reliably localise sentinel lymph nodes with a high detection rate typically in early tumour stages. Radiation exposure is low so that pregnancy is not a contraindication for sentinel lymph node scintigraphy. Even with high volumes of scintigraphic sentinel lymph node procedures surgeons, theatre staff and pathologists receive a radiation exposure <1 mSv/year so that they do not require occupational radiation surveillance.

    T lymphocytes infiltrate the microenvironment of breast cancer tumors and play a pivotal role in tumor immune surveillance. Relationships between the T-cell receptors (TCR) borne by T cells within tumors, in the surrounding tissues, and in draining lymph nodes are largely unexplored in human breast cancer. Consequently, information about the relative extent of possible T-cell exchange between these tissues is also lacking. Here, we have analyzed the TCR repertoire of T cells using multiplex PCR and high-throughput sequencing of the TCRβ chain in the tissues of tumor, adjacent nontumor, and axillary lymph nodes of breast cancer patients. T-cell repertoire diversity in tumors was lower than in lymph nodes, but higher than in nontumor tissue, with a preferential use of variable and joining genes. These data are consistent with the hypothesis that most of the T cells in tumors derive from the lymph node, followed by their expansion in tumor tissue. Positive nodes appeared to enhance T-cell infiltration into tumors and T-cell clonal expansion in lymph nodes. Additionally, the similarity in TCR repertoire between tumor and nontumor tissue was significantly higher in luminal-like, rather than basal-like, breast cancer. Our study elucidated the high heterogeneity of the TCR repertoire and provides potential for future improvements in immune-related diagnosis, therapy, and prognosis for breast cancer patients.

    The aim of this study was to evaluate biochemical recurrence-free survival (RFS) and to identify useful predictors of such survival in localized prostate cancer patients (cN0) and pelvic lymph node metastasis (pN+) treated with radical prostatectomy and pelvic lymph node dissection. This multicenter and retrospective study, assessed overall survival (OS), cancer specific survival (CSS) and biochemical recurrence-free survival (RFS), between January 2005 until December 2010 with 5 years of distance. We evaluated factors predicting long-term RFS in node positive prostate cancer patients. Thus, 30 patients were included. Median follow-up was 89.9±27.4 months. After surgery, patients were treated with surveillance (n=4, 13.5%), adjuvant hormone therapy (n=22, 73%) or combination of radio and hormone therapy, (n=4, 13.5%). During the follow-up, 50% of patients had biochemical recurrence, with a mean time period of 38±30 months. Five and 10-year RFS were 57% and 41% respectively. Extra lymph nodes extension (P=0.00021) and pathological margin status (P=0.0065) were independent predictors of 5-year RFS. Biochemical RFS of patients treated with radical prostatectomy and subclinical lymph node metastatic disease is adequate and multifactorial. However, this study identifies pathological margin status and extra lymph node extension as independent factors of b RFS. 4. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Full Text Available Background. Most institutions require a patient undergoing sentinel lymph node biopsy to go through nuclear medicine prior to surgery to be injected with radioisotope. This study describes the long-term results using intraoperative injection of radioisotope. Methods. Since late 2002, all patients undergoing a sentinel lymph node biopsy at the Yale-New Haven Breast Center underwent intraoperative injection of technetium-99m sulfur colloid. Endpoints included number of sentinel and nonsentinel lymph nodes obtained and number of positive sentinel and nonsentinel lymph nodes. Results. At least one sentinel lymph node was obtained in 2,333 out of 2,338 cases of sentinel node biopsy for an identification rate of 99.8%. The median number of sentinel nodes found was 2 and the mean was 2.33 (range: 1–15. There were 512 cases (21.9% in which a sentinel node was positive for metastatic carcinoma. Of the patients with a positive sentinel lymph node who underwent axillary dissection, there were 242 cases (54.2% with no additional positive nonsentinel lymph nodes. Advantages of intraoperative injection included increased comfort for the patient and simplification of scheduling. There were no radiation related complications. Conclusion. Intraoperative injection of technetium-99m sulfur colloid is convenient, effective, safe, and comfortable for the patient.

    lymphoma is the most frequent lymphoid neoplasm in our country. Its diagnosis is based on histopathological findings. The lymph node imprint has been used for more than 40 years. The aim was to establish the sensitivity, specificity, positive predictive value and negative predictive value of lymph node imprint and estimate the inter-observer rate. we did an observational, retrospective, prolective study, based on the lymph node imprint obtained by excisional biopsies over a period of 6 years. the inclusion criteria was met on 199 samples, 27.1 % were considered as reactive (n = 54), 16.1 % Hodgkin lymphoma (n = 32), 40.2 % (n = 80) non-Hodgkin lymphoma and 16.6 % (n = 33) as metastatic carcinoma. Comparing with the final histopathology report, the sensitivity and specificity of lymph node imprint were 88 % (0.81-0.95) and 64 % (0.55-0.73) respectively, the positive predictive value was 67 % (0.59-0.76) and the negative predictive value was 86 % (0.79-0.94). The interobserver kappa index was 0.467. the lymph node imprint remains as a useful tool for the diagnosis of lymphoid neoplasm. The agreement between observers was acceptable.

  12. Sentinel Lymph Node Biopsy in Nonmelanoma Skin Cancer Patients

    Full Text Available The management of lymph nodes in nonmelanoma skin cancer patients is currently still debated. Merkel cell carcinoma (MCC, squamous cell carcinoma (SCC, pigmented epithelioid melanocytoma (PEM, and other rare skin neoplasms have a well-known risk to spread to regional lymph nodes. The use of sentinel lymph node biopsy (SLNB could be a promising procedure to assess this risk in clinically N0 patients. Metastatic SNs have been observed in 4.5–28% SCC (according to risk factors, in 9–42% MCC, and in 14–57% PEM. We observed overall 30.8% positive SNs in 13 consecutive patients operated for high-risk nonmelanoma skin cancer between 2002 and 2011 in our institution. These high rates support recommendation to implement SLNB for nonmelanoma skin cancer especially for SCC patients. Completion lymph node dissection following positive SNs is also a matter of discussion especially in PEM. It must be remembered that a definitive survival benefit of SLNB in melanoma patients has not been proven yet. However, because of its low morbidity when compared to empiric elective lymph node dissection or radiation therapy of lymphatic basins, SLNB has allowed sparing a lot of morbidity and could therefore be used in nonmelanoma skin cancer patients, even though a significant impact on survival has not been demonstrated.

    A 63-year-old female patient was admitted to the authors' hospital for further diagnostic work-up for suspected reactivation of a previously successfully treated lymph node tuberculosis, which had been diagnosed 1 year prior to the current admission. The clinical signs consisted of worsening of the patient's general condition, negacervical lymphadenopathy, night sweats, dyspnea, and superficial inflammation of the right mamma. A contrast-enhanced CT scan of the neck, thorax and abdomen revealed a generalized enlargement of the cervical, axillar, mediastinal and retroperitoneal lymph nodes, multiple intrapulmonary nodular lesions with a diameter of up to 6 mm, and a substantial right-sided pleural effusion. Under the assumption of reactivation of a lymph node tuberculosis, the patient was initially treated with an extended tuberculostatic therapy. Because of disease progression another lymph node biopsy was performed revealing Hodgkin's disease of mixed-cellularity type with a partly histiocytic necrotizing, partly tuberculoid reaction. The biopsy was negative for acid-fast bacilli. Thereupon initiated chemotherapy according to the ABVD protocol led to a rapid amelioration of the clinical symptoms. In the clinical setting of suspected or confirmed lymph node tuberculosis malignant lymphoma should always be considered. This consideration is particular important since Hodgkin's disease is typically associated with a cellular immunosuppression predisposing the subject to tuberculosis.

  14. Accuracy of abdominal lymph node scintigraphy in tumor diagnostics

    1978-01-01

    In view of the diagnostical correspondence between lymph node scintigraphy and X-ray lymphograpy, this dissertation, which is based on 110 systematic comparative evaluations, examines the diagnostical weight of the scintigraphic criteria for tumor growth, discusses diagnostical discrepancies and confirms the efficacy of lymph node scintigraphy in detecting malignomas. In discussing the diagnostical results in the light of previous experience, the shortcomings of the nuclear medical method in tumor diagnostics are shown to be attributable to the uncertainty of the individual scintigraphic criteria. Owing to the variability of the lymph node system as to topography, anatomy and retention rate and the fact that it cannot morphologically be well differentiated in the scintigram, X-ray lymphography to verify the scintigraphic result and preclude misinterpretation remains an indispensable measure.

    Full Text Available ABSTRACTIntroduction and objective:Radical prostatectomy is a first-line treatment for localized prostate cancer. However, in some cases, biochemical recurrence associated with imaging-detected nodal metastases may happen. Herein, we aim to present the surgical technique for salvage lymph node dissection after radical prostatectomy.Materials and Methods:A 70 year-old asymptomatic man presented with a prostate-specific antigen (PSA of 7.45ng/ mL. Digital rectal examination was normal and trans-rectal prostate biopsy revealed a prostate adenocarcinoma Gleason 7 (3+4. Pre-operative computed tomography scan and bone scintigraphy showed no metastatic disease. In other service, the patient underwent a robotic-assisted radical prostatectomy plus obturador lymphadenectomy. Pathologic examination showed a pT3aN0 tumor. After 6 months of follow-up, serum PSA was 1.45ng/mL. Further investigation with 11C–Choline PET/CT revealed only a 2-cm lymph node close to the left internal iliac artery. The patient was counseled for salvage lymph node dissection.Results:Salvage lymph node dissection was uneventfully performed. Operative time was 1.5 hour, blood loss was minimal, and there were no intra- or postoperative complications. The patient was discharged from hospital in the 1st postoperative day. After 12 months of follow-up, his PSA was undetectable with no other adjuvant therapy.Conclusion:Robotic salvage pelvic lymph node dissection is an effective option for treatment of patients with biochemical recurrence after radical prostatectomy and only pelvic lymph node metastasis detected by C11-Choline PET/CT.

    Metastatic basal cell carcinoma (MBCC) of the skin is rare in occurrence and may initially elude proper diagnosis and management. We describe a case of MBCC to cervical lymph nodes, originally evaluated and treated surgically as metastatic thyroid carcinoma. After definitive diagnosis of MBCC was made, chemotherapy and concomitant radiation treatment were initiated; however, despite these measures, the patient then developed MBCC to the lung. Risk factors and current therapeutic modalities for MBCC are also discussed. In addition to the more commonly metastasizing carcinomas, metastases from a cutaneous basal cell carcinoma primary tumor should be considered when evaluating cervical lymph node metastases of an uncertain head and neck primary.

    Aim. The purpose of the present study was to characterize the morphological features of thymoma metastases in lymph nodes and to evaluate the possibility of their subtyping according to the 2004 WHO classification of thymus tumors. Materials and Methods. We reviewed 210 thymoma cases in our series of thymic epithelial tumors (TET), including their recurrences and lymphogenous metastases. Three cases of lymph node metastases, one case occurring synchronously with the primary tumor and one synchronously with the first relapse (both in intrathoracic location) and one case of metastasis observed in a laterocervical lymph node subsequently to two thymoma relapses were found. Results. The metastatic nodes were variably but extensively involved in all cases. The histological features were similar in both primary tumors and metastases. Thymoma metastases were subtyped according to the WHO classification as B3 (one case) and B2 (two cases), and distinctive features in comparison to metastatic epithelial neoplasias from other sites were observed. Conclusion. Thymoma lymph node metastases, although rare, can be subtyped according to the WHO classification on the basis of their morphological and immunohistochemical features. Clinically, the presence of nodal metastases may herald subsequent relapses and further metastases even in extrathoracic sites. PMID:25105128

    Purpose: The purpose of this study was to review management strategies with respect to systemic therapy, radiation therapy treatment techniques, and patient outcome (local regional control, distant metastases, and overall survival) in patients undergoing conservative surgery and radiation therapy (CS + RT) who had four or more lymph nodes involved at the time of original diagnosis. Methods and Materials: Of 1040 patients undergoing CS + RT at our institution prior to December 1989, 579 patients underwent axillary lymph node dissection. Of those patients undergoing axillary lymph node dissection, 167 had positive nodes and 51 of these patients had four or more positive lymph nodes involved and serve as the patient population base for this study. All patients received radiation therapy to the intact breast using tangential fields with subsequent electron beam boost to the tumor bed to a total median dose of 64 Gy. The majority of patients received regional nodal irradiation as follows: 40 patients received RT to the supraclavicular region without axilla to a median dose of 46 Gy, 10 patients received radiation to the supraclavicular region and axilla to a median dose of 46 Gy. Thirty of the 51 patients received a separate internal mammary port with a mixed beam of photons and electrons. One patient received radiation to the tangents alone without regional nodal irradiation. Adjuvant systemic therapy was used in 49 of the 51 patients (96%) with 27 patients receiving chemotherapy alone, 14 patients receiving cytotoxic chemotherapy and tamoxifen, and 8 patients receiving tamoxifen alone. Results: As of December 1994, with a minimum evaluable follow-up of 5 years and a median follow-up of 9.29 years, there have been 18 distant relapses, 2 nodal relapses, and 5 breast relapses. Actuarial statistics reveal a 10-year distant metastases-free rate of 65%, 10-year nodal recurrence-free rate of 96%, and a 10-year breast recurrence-free rate of 82%. All five patients who

    Lymph node infection is the most frequent localization of extrapulmonary tuberculosis. However, there is still no consensus on the length of antimicrobial treatment. We conducted a retrospective study in the Department of infectious diseases and internal medicine in the Amiens Teaching Hospital, France. All patients diagnosed with lymph node tuberculosis between 1998 and 2007 were included; some patients presented with bi- or multifocal tuberculosis. The aim of the study was a practice analysis. We studied 48 medical records, 16 were excluded for lack of more than 40% of data or because lymph node tuberculosis was non-active. The mean age of the 32 patients included was 49 years. The mean duration of treatment was 10.9 months (standard deviation 2.6, median 11, range 6-18). There was no statistical age difference between subgroups (lymph node tuberculosis versus multifocal tuberculosis). There was no significant difference between the 6-month treatment group and the 9-month treatment group in term of clinical response. One relapse was diagnosed, eight patients (25%) were lost to follow-up at 1 year after treatment. DISCUSSION AND REVIEW: No reliable published data was found as to the optimal duration of treatment. A high quality clinical trial should be carried out to suggest a consensus. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

    Castleman's disease, or giant lymph node hyperplasia, is a rare disorder of the lymphoid tissue that causes lymph node enlargement. It is considered benign in its localized form, but aggressive in the multicentric type. The definitive diagnosis is based on postoperative pathological findings. The aim here was to describe a case of retroperitoneal unicentric Castleman's disease in the retroperitoneum. A 61-year old white male with weight loss and listlessness presented with moderate arterial hypertension and leukopenia. Abdominal tomography revealed a 5 x 4 x 5 cm oval mass of low attenuation, with inner calcification and intense enhancement on intravenous contrast, located in the retroperitoneal region, between the left kidney and the aorta, at the renal hilus. Exploratory laparotomy revealed a non-pulsatile solid oval mass situated in the retroperitoneum, adjacent to the left renal hilus. The retroperitoneal lesion was removed in its entirety. Examination of frozen samples revealed benign lymph node tissue and histopathological examination of the surgical sample revealed hyaline-vascular giant lymph node hyperplasia (Castleman's disease). The patient was discharged on the 12th day without significant events. Two months after the operation, the patient was readmitted with severe cardiac insufficiency, acute renal failure and bronchopneumonia, which progressed to acute respiratory insufficiency, sepsis and death.

    1976-01-01

    Tracheobronchial lymph nodes accumulate a portion of material deposited in the deep lung following inhalation of relatively insoluble particles. Experiments involving a variety of compounds, inhaled singly or repeatedly, indicate that the kinetics of lymph node uptake are fairly independent of particle characteristics and mammalian species. The buildup per unit weight of nodal tissue compared with that of lung tissue, with time, can be represented by a linear logarithmic function. However, since the scatter in experimental points may be large at any given time after inhalation exposure, a number of different kinetic descriptions of uptake can be derived. The logarithmic pattern of accumulation can be approximated over an extended time range (several years) by use of a combination of first-order kinetics of loss from the lung and of buildup in lymph nodes, but it is recognized that the processes are much more complicated than this treatment would indicate. Clearance (loss) from the lymph nodes is not well defined, but this aspect is discussed in light of the kinetic models presented

  12. LCP nanoparticle for tumor and lymph node metastasis imaging

    Science.gov (United States)

    Tseng, Yu-Cheng

    A lipid/calcium/phosphate (LCP) nanoparticle formulation (particle diameter ˜25 nm) has previously been developed to delivery siRNA with superior efficiency. In this work, 111In was formulated into LCP nanoparticles to form 111In-LCP for SPECT/CT imaging. With necessary modifications and improvements of the LCP core-washing and surface-coating methods, 111In-LCP grafted with polyethylene glycol exhibited reduced uptake by the mononuclear phagocytic system. SPECT/CT imaging supported performed biodistribution studies, showing clear tumor images with accumulation of 8% or higher injected dose per gram tissue (ID/g) in subcutaneous, human-H460, lung-cancer xenograft and mouse-4T1, breast cancer metastasis models. Both the liver and the spleen accumulated ˜20% ID/g. Accumulation in the tumor was limited by the enhanced permeation and retention effect and was independent of the presence of a targeting ligand. A surprisingly high accumulation in the lymph nodes (˜70% ID/g) was observed. In the 4T1 lymph node metastasis model, the capability of intravenously injected 111In-LCP to visualize the size-enlarged and tumor-loaded sentinel lymph node was demonstrated. By analyzing the SPECT/CT images taken at different time points, the PK profiles of 111In-LCP in the blood and major organs were determined. The results indicated that the decrement of 111In-LCP blood concentration was not due to excretion, but to tissue penetration, leading to lymphatic accumulation. Larger LCP (diameter ˜65 nm) nanoparticles were also prepared for the purpose of comparison. Results indicated that larger LCP achieved slightly lower accumulation in the tumor and lymph nodes, but much higher accumulation in the liver and spleen; thus, larger nanoparticles might not be favorable for imaging purposes. We also demonstrated that LCP with a diameter of ˜25 nm were better able to penetrate into tissues, travel in the lymphatic system and preferentially accumulate in the lymph nodes due to 1) small

    To investigate the prognostic significance of the number of lymph nodes removed in colorectal cancer (CRC) patients with no metastatic lymph node. The clinicopathological data of 461 CRC patients was analyzed. In order to compare the survival of patients who had fewer lymph nodes removed versus the survival of patients who had 1-3 metastatic lymph node(s), a separate group of 74 N1 disease patients were also included in the study. All patient data were collected prospectively. Kaplan-Meier method was used for calculation and plotting of the survival curves of the patient groups, and log-rank test was used for the comparison of the survival curves. Cancer-specific survival (CSS) rates of patients who had 1-7 lymph node(s) and 8-11 lymph nodes removed were significantly worse than those who had 12 or more lymph nodes removed (p = 0.006 and p = 0.037, respectively), while CSS was not significantly different between those who had 1-7 versus 8-11 lymph node(s) removed (p = 0.647); this grouping had independent prognostic significance in Cox analysis (p = 0.006). CSS of patients with N1 disease was not significantly different from those who had 1-7 and 8-11 lymph node(s) removed (p = 0.312 and p = 0.165, respectively), while it was significantly worse than CSS of patients who had 12 or more lymph nodes removed (p = 0.001). In colorectal cancer patients whose removed lymph nodes are non-metastatic, removal of at least 12 lymph nodes will determine the lymph node status reliably. Copyright © 2014 Surgical Associates Ltd.

    The relationship between the number of harvested lymph nodes (HLNs) and prognosis of gastric cancer patients without an involvement of lymph nodes has not been well-evaluated. The objective of this study is to further explore this issue. We collected data from 399 gastric cancer patients between November 2006 and October 2011. All of them were without metastatic lymph nodes. Survival analyses showed that statistically significant differences existed in the survival outcomes between the two groups allocated by the total number of HLNs ranging from 16 to 22. Therefore, we adopted 22 as the cut-off value of the total number of HLNs for grouping (group A: HLNs patients at the T4 stage was better in group B than in group A (76.9% vs. 58.5%; P=0.004). An analysis of multiple factors elucidated that the total number of HLNs, T stage, operation time and age were independently correlated factors of prognosis. Regarding gastric cancer patients without the involvement of lymph nodes, an HLN number ≥22 would be helpful in prolonging their overall survival, especially for those at T4 stage. The total number of HLNs was an independent prognostic factor for this population of patients.

    Full Text Available Angela M Gonella-Diaza, Luz Zoraya Duarte, Sergio Dominguez, Pedro A SalazarClínica de Grandes Animales, Facultad de Medicina Veterinaria y de Zootecnia, Universidad Cooperativa de Colombia, Bucaramanga, Santander, ColombiaAbstract: In this freemartin case report the authors present the clinical and morphological findings of a freemartin ewe with an abnormal position of two lymph nodes. Freemartins, infertile females from mixed-sex twin pregnancies, are chimeras, having two cell populations: one of their own (XX DNA and one from their male twin (XY DNA. Freemartins can have varying degrees of phenotypic masculinization, including, in some cases, having active male gonads and exhibiting male behaviors such as heat detection and aggressiveness. During the clinical examination of the freemartin ewe, a morphological abnormality of the vulva, the presence of scrotal sacs, and a lack of mammary tissue development were noted. On inspection of the vaginal channel, an extremely enlarged clitoris, resembling a penis, was found. The clinical evidence suggested freemartinism. After the karyotyping diagnosis confirmation, a necropsy was performed and samples were taken for histology and immunohistochemistry. There were two structures found in the scrotal sacs; however, these were found to be lymph nodes, not testicles, and this was confirmed by CD3 lymph protein coloration. On histological study, the phallic structure showed corpus cavernosum and tunica albuginea. The testicles were found retained inside the abdominal cavity, with the presence of atrophic seminiferous tubules. Although the position of the testicles in freemartins has been reported as highly variable, this is the first time, to the best of the authors' knowledge, that a case has been reported where lymph nodes have been found inside the scrotal sacs. It is possible that these were the inguinal lymph nodes, trapped inside the scrotum during fetal growth and development.Keywords: freemartinism

    2014-12-01

    Cervical node metastasis of malignant ameloblastoma is extremely rare. Because of its rarity, there is no standard treatment modality in a single lymph node metastasis in malignant ameloblastoma. Eleven patients of malignant ameloblastoma involving a single cervical lymph node metastasis and one new case were reviewed. Neck treatment was classified into neck dissection and simple excision. Local nodal recurrence, distant metastasis and follow-up periods were investigated. Eight patients were treated with neck dissection (group A) and four patients underwent a simple node excision (group B). Two patients in group A experienced multiple organ metastases such as liver and lung seven months and 13 years after neck dissection respectively. The other patients showed no recurrence and metastasis. In group B, there was no report of a regional neck recurrence and distant metastasis during follow-up of 1-7 years. Multiple nodes metastasis requires a radical neck dissection; however, simple excision with close follow-up may be used in a single node metastasis in malignant ameloblastoma.

    Vulvar melanoma is a rare malignant tumour. Its surgical excision is the mainstay of treatment whilst the surgical management of regional lymph nodes remains controversial; on the contrary elective inguinofemoral lymphadenectomy causes considerable morbidity. Lymphoscintigraphy (LS) and sentinel lymph node biopsy (SLNB) are accurate staging procedures of lymph node status in breast cancer and cutaneous melanoma patients. In this retrospective paper we report our experience of LS and SLNB in vulvar melanoma patients. Twenty-two consecutive patients with a diagnosis of vulvar melanoma were treated at our institute: patients with clinically positive groin nodes or with previous surgery on the primary tumour were excluded. Twelve were selected for our analysis. All patients underwent sentinel lymph node localization with LS the day before surgery and the surgical procedure of SLNB associated with radical surgery. Six patients had metastatic SLNB and in five of six (83.3%) it was the only positive node. In the other six patients SLNB was negative for metastatic disease. No skip metastases were observed. In SLNB negative patients the mean Breslow thickness was 2.06 mm (range: 0.60-7.10) and only one patient showed a high Breslow thickness (patient 8). In SLNB positive patients the mean Breslow thickness was 4.33 mm (1.8-6.0). Our data indicate that, even in vulvar melanoma, the sentinel lymph node pathological status predicts the pathological status of the remaining groin nodes and suggests that elective groin dissection can be spared in cases of a negative SLNB. Breslow thickness (<1 mm) was not predictive of negative nodes. (orig.)

    Recently, lymph node micrometastasis has been evaluated for its prognostic value in gastric cancer. Lymph node micrometastasis cannot be detected via a usual pathologic examination, but it can be detected by using some other techniques including immunohistochemistry and reverse transcription-polymerase chain reaction assay. With the development of such diagnostic techniques, the detection rate of lymph node micrometastasis is constantly increasing. Although the prognostic value of lymph node ...

    Objective: To evaluate the potential influence of transaxillary augmentation mammoplasty on future detection of sentinel lymph node. Materials and methods: Prospective controlled study where 22 patients were selected and divided into two groups (post-mammoplasty and control) corresponding to 43 breasts (22 in the post-mammoplasty group and 21 in the control group) evaluated by lymphoscintigraphy immediately after periareolar {sup 99m}Tc-phytate injections. In the statistical analysis, p values < 0.05 were considered as significant. Results: All the breasts in the post-mammoplasty group presented lymphatic drainage to the axillary chain, with no difference as compared with the control group (p 0.488). The average number of hot lymph nodes was 1.27 {+-} 0.46 in the post-mammoplasty group, and 1.33 {+-} 0.58 in the control group (p = 0.895). The mean time required to visualize the first lymph node was 3.14 {+-} 4.42 minutes in the post mammoplasty group, and 5.48 {+-} 5.06 minutes in the control group (p 0.136). Conclusion: Transaxillary augmentation mammoplasty did not affect the future detection of sentinel lymph node. (author)

  8. Results of surgery without axillary dissection for breast cancer

    We believe that routine axillary dissection for relatively early breast cancer should be reconsidered in view of the low incidence of lymph node metastasis and its effects on postoperative quality of life. We have performed bioptic lumpectomy to examine histological type, invasive tumor size, histological infiltration, and lymphatic invasion and have avoided axillary dissection in cases with a low risk of lymph node metastasis. In 126 cases of T0, T1a, or T2a breast cancers less than 3 cm in diameter in which axillary dissection was not performed, axillary recurrence was observed in 2 cases. Both patients underwent salvage procedures and are alive without disease. Furthermore, axillary recurrence was not observed in 23 cases treated with tangent irradiation and breast-preserving surgery. These findings suggest that axillary recurrence is possible in cases with previous indications for avoiding axillary dissection and that breast irradiation may prevent axillary recurrence. (author)

    The incidence of melanoma in children is uncommon, being particularly rare in children under 10 years-old. However, this disease is increasing by a mean of 2% per year. As in adults, the lymph node status is the most important prognostic factor, crucial to performing the selective sentinel lymph node biopsy (SLNB). We report 3 cases of paediatric patients of 3, 4 and 8 years-old, in which SLNB was performed for malignant melanoma. Paediatric age implies greater technical difficulty to the scintigraphy scan due to poor patient cooperation, with mild sedation required in some cases, and only being able to acquire planar images in other cases. SPECT/CT was only performed in the oldest patient. In our cases, SLNB was useful for selecting the least invasive surgery in order to reduce morbidity.

    Although various haematologic abnormalities are known to occur with tuberculosis, association of immune thrombocytopenia with tuberculosis is uncommon. We report a case of retroperitoneal lymph node tuberculosis who presented with ITP. A 76 year old female was admitted to our hospital with oral mucosal bleed and petechial lesions over extremities and abdomen. A diagnosis of immune thrombocytopenia (ITP) was established. Intravenous Anti-D immunoglobulin and Dexamethasone therapy was started, but failed to elicit any sustained platelet response. CT abdomen revealed multiple retroperitoneal lymph nodes with central necrosis. Histopathology (HPE) of these revealed caseating lymphadenitis suggestive of tuberculosis. After 2 months of anti-tuberculous therapy, the platelet counts returned to normal and patient was off all therapy for ITP thereby suggesting likely association between tuberculosis and immune thrombocytopenia.

    Full Text Available Papillary carcinoma is a prominent malignancy originating from follicular cells. This disease generally shows an indolent character, but patients demonstrating certain clinicopathological features have a dire prognosis. At present, Western countries adopted almost routine total thyroidectomy with radioactive iodine (RAI ablation, while limited thyroidectomy with extensive prophylactic lymph node dissection has traditionally been performed for most patients in Japan. Recently, accurate evaluation of carcinoma stage can be performed on preoperative imaging studies, especially on ultrasonography. It is therefore important to treat papillary carcinoma patients depending on clinicopathological features rather than in a stereotyped fashion. In this paper, appropriate extension of thyroidectomy and lymph node dissection is discussed based on Western and recently published Japanese guidelines and the experience in Kuma Hospital.

    Full Text Available Introduction: In Brazil, about 26,000 cases of colorectal cancer are diagnosed per year. Pa- tients considered at the early stage of disease (without lymph node evolve with tumor relapse or recurrence in up to a quarter of cases, probably due to understaging. Objective: Research on ex vivo sentinel lymph node in patients with colorectal adenocarcinoma. Materials and methods: We studied 37 patients who underwent curative surgical resection. The marker used to identify lymph nodes was patent blue dye injected into the peritu- moral submucosa of the open surgical specimen immediately after its removal from the abdominal cavity. Results: Ex vivo identification of sentinel lymph node with marker occurred in 13 (35.1% patients. The sensitivity was 40% and 60% false negative. The detailed histological examina- tion of sentinel lymph nodes with multilevel section and immunohistochemistry showed metastasis in one (4.3% individual, considered ultra-staging. Conclusion: The ex vivo identification of sentinel lymph node had questionable benefits, and worse results when include patients with rectal cancer. Restaging of one patient was possible after multilevel section and immunohistochemistry of the sentinel lymph node, but more research is needed to evaluate the role of micrometastases in patients with colorectal cancer. Resumo: Introdução: No Brasil, a cada ano são diagnosticados cerca de 26.000 casos de câncer colorre- tal. Pacientes com estadiamento considerado inicial, sem linfonodo metastático, evoluem com recorrência ou recidiva do tumor em até um quarto dos casos, por provável subesta- diamento. Objetivo: pesquisar sobre linfonodo-sentinela ex vivo em pacientes com adeno- carcinoma colorretal. Objetivo: Foram estudados 37 pacientes, submetidos à cirurgia oncológica com ressecção caráter curativo. O marcador de linfonodos utilizado foi o corante azul patente, injetado na submucosa peritumoral da peça cirúrgica aberta imediatamente

    Thirty-six patients with advanced carcinoma of the uterine cervix and with iliac or para-aortic nodes interpreted as un-equivocally positive on lymphangiography have received radiation therapy to the para-aortic area at the Department of Therapeutic Radiology at Tufts-New England Medical Center Hospital. Of 29 patients who received para-aortic area irradiation as part of their initial treatment, local control was achieved in 18 patients (62%). Overall, four patients developed major complications requiring surgical intervention. Detailed results and our current pre-treatment evaluation policy including lymphangiography, percutaneous needle biopsy and selective extra-peritoneal lymph node biopsy will be discussed

    2000-01-01

    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

    Full Text Available Introduction: Differentiated thyroid carcinoma (DTC account up to 90% of all thyroid malignacies, and represents the most common malignant tumors of endocrine system. The incidence of papillary thyroid carcinoma (PTC, especially small tumors is rapidly increasing during past three decades. At the time of diagnosis, the incidence of lymph node metastases (LNM ranges from 80 to 90%. During the last 15 years, LNM were recognized as bad prognostic factor for both local-regional relapse (LRR and cancer specific survival. There is general agreement that neck dissections are indicated in cases of clinically apparent LNM. The subject of the current controversy is the surgical treatment of occult LNM that remain unrecognized on preoperative diagnosis (cN0.

    To evaluate factors associated with non identification of the sentinel lymph node (SLN) in lymphoscintigraphy of breast cancer patients and analyze the relationship with SLN metastases. A single-center, cross-sectional and retrospective study was performed. Forty patients with lymphoscintigraphy without sentinel lymph node identification (negative lymphoscintigraphy - NL) were enrolled. The control group included 184 patients with SLN identification (positive lymphoscintigraphy - PL). Evaluated factors were age, body mass index (BMI), tumor size, histology, localization, preoperative breast lesion hookwire (harpoon) marking and SLN metastases. The statistical analysis was performed with uni- and multivariate logistic regression models and matched-pairs analysis. Age (p=0.036) or having BMI (p=0.047) were the only factors significantly associated with NL. Being ≥60 years with a BMI ≥30 increased the odds of having a NL 2 and 3.8 times, respectively. Marking with hookwire seems to increase the likelihood of NL, but demonstrated statistical significance is lacking (p=0.087). The other tested variables did not affect the examination result. When controlling for age, BMI and marking with the harpoon, a significant association between lymph node metastization and NL was not found (p=0.565). The most important factors related with non identification of SLN in the patients were age, BMI and marking with hook wire. However, only the first two had statistical importance. When these variables were controlled, no association was found between NL and axillary metastases. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM. All rights reserved.

    To examine correlations between the uptake of 2-deoxy-2-[18F]fluoro-D-glucose (FDG) by primary tumours and axillary lymph nodes, and clinical and biological tumour prognostic parameters, in patients with newly diagnosed breast cancer. Newly diagnosed breast cancer patients who had received a dual-phased FDG positron emission tomography/computed tomography scan for pretreatment staging were enrolled retrospectively. Maximal standardized uptake values at 1 h (SUV1), 2 h (SUV2), and retention indices (RI) of the tumours and ipsilateral axillary lymph nodes were measured. SUV and RI were compared with clinical and biological prognostic parameters. A total of 32 patients participated in the study. Tumour FDG uptake correlated with histological grade and tumour size. FDG uptake in axillary lymph nodes correlated positively with lymph node status, metastasis status and clinical stage. RI values for the tumour and lymph nodes were significantly positively correlated with human epidermal growth factor receptor-2 positivity. FDG uptake in tumours and lymph nodes showed correlations with some clinical and biological parameters, and may serve as a predictive marker of tumour biological behaviour in breast cancer. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    To investigate risk factors associated with right paraesophageal lymph node (RPELN) metastasis in patients with papillary thyroid carcinoma (PTC) and to determine the indications for right lymph node dissection. Clinicopathologic data from 829 patients (104 men and 725 women) with PTC, operated on by the same thyroid surgery team at the First Affiliated Hospital of Harbin Medical University from January 2013 to May 2017, were analyzed. Overall, 309 patients underwent total thyroidectomy with bilateral lymph node dissection, 488 underwent right thyroid lobe and isthmic resection with right central compartment lymph node dissection, and 32 underwent near-total thyroidectomy (ipsilateral thyroid lobectomy with contralateral near-total lobectomy) with bilateral lymph node dissection. The overall rate of central compartment lymph node metastasis was 43.5% (361/829), with right central compartment lymph node and RPELN metastasis rates of 35.5% (294/829) and 19.1% (158/829), respectively. Tumor size, number, invasion, and location, lymph node metastasis, right central compartment lymph node metastasis, and right lateral compartment lymph node metastasis were associated with RPELN in the univariate analysis, whereas age and sex were not. Multivariate analysis identified tumors with a diameter ≥ 1 cm, multiple tumors, tumors located in the right lobe, right central compartment lymph node metastasis, and right lateral compartment lymph node metastasis as independent risk factors for RPELN metastasis. Lymph node dissection, including RPELN dissection, should be performed for patients with PTC with a tumor diameter ≥ 1 cm, multiple tumors, right-lobe tumors, right central compartment lymph node metastasis, or suspected lateral compartment lymph node metastasis.

    Identification of lymph nodes and pathological analysis is crucial for the correct staging of colon cancer. Lymph nodes that drain directly from the tumor area are called "sentinel nodes" and are believed to be the first place for metastasis. The purpose of this study was to perform sentinel node mapping in vivo with indocyanine green and ex vivo with methylene blue in order to evaluate if the sentinel lymph nodes can be identified by both techniques. Patients with colon cancer UICC stage I-III were included from two institutions in Denmark from February 2015 to January 2016. In vivo sentinel node mapping with indocyanine green during laparoscopy and ex vivo sentinel node mapping with methylene blue were performed in all patients. Twenty-nine patients were included. The in vivo sentinel node mapping was successful in 19 cases, and ex vivo sentinel node mapping was successful in 13 cases. In seven cases, no sentinel nodes were identified. A total of 51 sentinel nodes were identified, only one of these where identified by both techniques (2.0%). In vivo sentinel node mapping identified 32 sentinel nodes, while 20 sentinel nodes were identified by ex vivo sentinel node mapping. Lymph node metastases were found in 10 patients, and only two had metastases in a sentinel node. Placing a deposit in relation to the tumor by indocyanine green in vivo or of methylene blue ex vivo could only identify sentinel lymph nodes in a small group of patients.

    Sentinel lymph node biopsy (SLNB) is the most useful tool for node staging in melanoma. SLNB facilitates selective dissection of lymph nodes, that is, the performance of lymphadenectomy only in patients with sentinel nodes positive for metastasis. Our aim was to assess the cost of SLNB, given that this procedure has become the standard of care for patients with melanoma and must be performed whenever patients are to be enrolled in clinical trials. Furthermore, the literature on the economic impact of SLNB in Spain is scarce. From 2007 to 2010, we prospectively collected data for 100 patients undergoing SLNB followed by transhilar bivalving and multiple-level sectioning of the node for histology. Our estimation of the cost of the technique was based on official pricing and fee schedules for the Spanish region of Murcia. The rate of node-positive cases in our series was 20%, and the mean number of nodes biopsied was 1.96; 44% of the patients in the series had thin melanomas. The total cost was estimated at between €9486.57 and €10471.29. Histopathology accounted for a considerable portion of the cost (€5769.36). The cost of SLNB is high, consistent with amounts described for a US setting. Optimal use of SLNB will come with the increasingly appropriate selection of patients who should undergo the procedure and the standardization of a protocol for histopathologic evaluation that is both sensitive and easy to perform.

    This study compares clinicopathological parameters with novel molecular markers for predicting cervical lymph node metastasis in salivary gland cancer. Three hundred sixteen salivary gland carcinomas were included in this study. Genomic epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2), phosphatase and tensin homolog (PTEN), and hepatocyte growth factor receptor (MET) was determined by fluorescence in situ hybridization (FISH). Chi-square tests, multivariate regression, and Kaplan-Meier survival analysis were used for statistics. Nodal staging determines long-term survival. Clinicopathological parameters associated with positive neck nodes are advanced age (p = .006), T3/T4 classification, histological high-grade malignancy, and diagnosis of salivary duct carcinoma (p < .001 each). Neck node metastases also correlate with copy number gain of EGFR (p = .004) and HER2, aberration of MET, and deletion of PTEN (p < .001 each). Multivariate analysis showed SDC (p = .002) to be the strongest predictor of lymph node metastasis, followed by MET aberration (p = .009), T3/T4 classification (p = .017), PTEN deletion (p = .042), and adenocarcinoma not otherwise specified (NOS; p = .047). The histological subtype is crucial for decisions regarding neck dissection. New molecular parameters may also indicate elective treatment of the neck. Copyright © 2013 Wiley Periodicals, Inc.

    Superparamagnetic iron oxide nanoparticles (SPIONs) are tested to identify sentinel lymph nodes (SLNs) to exploit the advantages of targeted pelvic SLN dissection (sPLND), while circumventing the disadvantages of established radioactive labeling. Here we review recent studies about sPLND in prostate cancer (PCa), including the first results of SLN detection using intraprostatic SPION-injection. A recent systematic literature review reveals that the diagnostic accuracy of sPLND is comparable with extended PLND (ePLND). sPLND combined with ePLND achieve better node removal by increasing the number of affected nodes. The first sentinel-based nomogram predicting lymph node invasion is established. A sentinel-nomogram update provides comparative predictions relative to ePLND models. sPLND using a magnetometer and SPIONs as a tracer is successful whenever applied to PCa, and SLN identification using MRI after intraprostatic injection of SPIONs is feasible. SLNs are present in an unexpectedly high number outside the ePLND template. SLN detection outside the ePLND template and the increased diagnostic value of sPLND compared with ePLND supports the individualized extension of PLND using sPLND in PCa. SPION-MRI, combined with a hand-held magnetometer, provides a nonradioactive technique for preoperative and intraoperative SLN localization. Further studies are required to evaluate the effects of sPLND on oncological outcomes.

    BACKGROUND: The value of level III axillary clearance is contentious, with great variance worldwide in the extent and levels of clearance performed. OBJECTIVE: To determine rates of level III positivity in patients undergoing level I-III axillary clearance, and identify which patients are at highest risk of involved level III nodes. METHODS: From a database of 2850 patients derived from symptomatic and population-based screening service, 1179 patients who underwent level I-III clearance between the years 1999-2007 were identified. The pathology, surgical details, and prior sentinel nodes biopsies of patients were recorded. RESULTS: Eleven hundred seventy nine patients had level I-III axillary clearance. Of the patients, 63% (n = 747) were node positive. Of patients with node positive disease, 23% (n = 168) were level II positive and 19% (n = 141) were level III positive. Two hundred fifty patients had positive sentinel node biopsies prior to axillary clearance. Of these, 12% (n = 30) and 9% (n = 22) were level II and level III positive, respectively. On multivariate analysis, factors predictive of level III involvement in patients with node positive disease were tumor size (P < 0.001, OR = 1.36; 95% CI: 1.2-1.5), invasive lobular disease (P < 0.001, OR = 3.6; 95% CI: 1.9-6.95), extranodal extension (P < 0.001, OR = 0.27; 95% CI: 0.18-0.4), and lymphovascular invasion (P = 0.04, OR = 0.58; 95% CI: 0.35-1). Lobular invasive disease (P = 0.049, OR = 4.1; 95% CI: 1-16.8), extranodal spread (P = 0.003, OR = 0.18; 95% CI: 0.06-0.57), and having more than one positive sentinel node (P = 0.009, OR = 4.9; 95% CI: 1.5-16.1) were predictive of level III involvement in patients with sentinel node positive disease. CONCLUSION: Level III clearance has a selective but definite role to play in patients who have node positive breast carcinoma. Pathological characteristics of the primary tumor are of particular use in identifying those who are at various risk of level III nodal

    Objective: To investigate the usefulness of gray-scale contrast-enhanced ultrasonography for detecting sentinel lymph nodes. Methods: Contrast-enhanced ultrasonography was performed in five normal dogs (four female and one male) after subcutaneous administration of a sonographic contrast agent (Sonovue, Bracco, Milan, Italy). Four distinct regions in each animal were examined. After contrast-enhanced ultrasonography, 0.8 ml of blue dye was injected into the same location as Sonovue and the sentinel lymph nodes were detected by surgical dissection. The findings of contrast-enhanced ultrasonography were compared with those of the blue dye. Results: Twenty-one sentinel lymph nodes were detected by contrast-enhanced ultrasonography while 23 were identified by blue dye with surgical dissection. Compared with the blue dye, the detection rate of enhanced ultrasonography for the sentinel lymph nodes is 91.3% (21/23). Two patterns of enhancement in the sentinel lymph nodes were observed: complete enhancement (5 sentinel lymph nodes) and partial enhancement (16 sentinel lymph nodes). The lymphatic channels were demonstrated as hyperechoic linear structures leading from the injection site and could be readily followed to their sentinel lymph nodes. Histopathologic examination showed proliferation of lymphatic follicles or lymphatic sinus in partial enhanced sentinel lymph nodes while normal lymphatic tissue was demonstrated in completely enhanced sentinel lymph nodes. Conclusions: Sonovue combined with gray-scale contrast-enhanced ultrasonography may provide a feasible method for detecting sentinel lymph nodes.

    This study aimed to determine the relationship between CK19 mRNA copy number in sentinel lymph nodes (SLN) assessed by one-step nucleic acid amplification (OSNA) technique, and non-sentinel lymph nodes (NSLN) metastization in invasive breast cancer. A model using total tumor load (TTL) obtained by OSNA technique was also constructed to evaluate its predictability. We conducted an observational retrospective study including 598 patients with clinically T1-T3 and node negative invasive breast cancer. Of the 88 patients with positive SLN, 58 patients fulfill the inclusion criteria. In the analyzed group 25.86% had at least one positive NSLN in axillary lymph node dissection. Univariate analysis showed that tumor size, TTL and number of SLN macrometastases were predictive factors for NSLN metastases. In multivariate analysis just the TTL was predictive for positive NSLN (OR 2.67; 95% CI 1.06-6.70; P = 0.036). The ROC curve for the model using TTL alone was obtained and an AUC of 0.805 (95% CI 0.69-0.92) was achieved. For TTL >1.9 × 10 5 copies/μL we got 73.3% sensitivity, 74.4% specificity and 88.9% negative predictive value to predict NSLN metastases. When using OSNA technique to evaluate SLN, NSLN metastases can be predicted intraoperatively. This prediction tool could help in decision for axillary lymph node dissection.

    Identification of a gene expression signature in primary breast tumors that could classify patients by lymph node status would allow patients to avoid the morbidities of surgical disruption of the lymph nodes. Attempts to identify such a signature have, to date, been unsuccessful. Because breast tumor subtypes have unique molecular characteristics and different sites of metastasis, molecular signatures for lymph node involvement may vary by subtype. Gene expression data was generated from HG U133A 2.0 arrays for 135 node positive and 210 node negative primary breast tumors. Intrinsic subtype was assigned using the BreastPRS. Differential gene expression analysis was performed using one-way ANOVA using lymph node status as the variable with a False-discovery rate basal-like (27%), HER2-enriched (14%) luminal B (7%) and normal-like (1%). Basal-like and luminal A tumors were less likely to have metastatic lymph nodes (35% and 37%, respectively) compared to luminal B or HER2-enriched (52% and 51%, respectively). No differentially expressed genes associated with lymph node status were detected when all tumors were considered together or within each subtype. Gene expression patterns from the primary tumor are not able to stratify patients by lymph node status. Although the primary breast tumor may influence tumor cell dissemination, once metastatic cells enter the lymphatics, it is likely that characteristics of the lymph node microenvironment, such as establishment of a pre-metastatic niche and release of pro-survival factors, determine which cells are able to colonize. The inability to utilize molecular profiles from the primary tumor to determine lymph node status suggest that other avenues of investigation, such as how systemic factors including diminished immune response or genetic susceptibility contribute to metastasis, may be critical in the development of tools for non-surgical assessment of lymph node status with a corresponding reduction in downstream sequelae

  11. Metachronous mediastinal lymph node metastasis from ascending colon cancer: A case report and literature review

    Directory of Open Access Journals (Sweden)

    Kosuke Toda

    Full Text Available Introduction: Metachronous mediastinal lymph node metastasis without pulmonary metastasis is extremely rare in colorectal cancer, which makes the clinical diagnosis difficult and treatment strategy unclear. Prsentation of case: A case was a 59-year-old man, who had undergone right hemicolectomy for ascending colon cancer 2 years and 8 months previously, presented with enlarged mediastinal lymph nodes. 18F-fluorodeoxyglucose (FDG positron emission tomography revealed FDG was accumulated only into the mediastinal lymph nodes. Serum carcinoembryonic antigen (CEA level was within the normal range. Six months later, the size and FDG uptake of the mediastinal lymph nodes had increased. We assumed a possibility that the mediastinal lymph nodes were metastasized from ascending colon cancer and so performed thoracoscopic-assisted resection of the mediastinal lymph nodes. Histopathological analysis revealed the resected lymph nodes were filled with moderately differentiated adenocarcinoma and a diagnosis of mediastinal lymph nodes metastasis from previously-resected ascending colon cancer was made. The patient was postoperatively followed for more than 1 year and 8 months without any sign of recurrence. Discussion: Only 7 cases of metachronous mediastinal lymph node metastasis from colorectal cancer, including our case, have been reported in the English literature. It is difficult to clinically diagnose mediastinal lymph node metastasis. Conclusion: We report a rare case of metachronous mediastinal lymph node metastasis from ascending colon cancer with literature review. If the mediastinal lymph nodes are enlarged after colorectal cancer resection, we need to make a treatment strategy as well as a diagnostic approach considering the possibility of mediastinal lymph node metastasis.

    Several clinical studies analyze axillary treatment in women with early-stage breast cancer because of changes in the indication for axillary lymph node dissection. The aim of the study is to analyze the impact of axillary radiotherapy in disease-free and overall survival in women with early breast cancer treated with lumpectomy. Retrospective study in women with initial stages of breast carcinoma treated by lumpectomy. A comparative analysis of high-risk women with axillary lymph node involvement who received axillary radiotherapy with the group of women with low risk without radiotherapy was performed. Logistic regression was used to determine factors influencing survival and lymphedema onset. A total of 541 women were included in the study: 384 patients (71%) without axillary lymph node involvement and 157 women (29%) with 1-3 axillary lymph node involvement. Patients with axillary radiotherapy had a higher number of metastatic lymph node compared to non-irradiated (1.6±0.7 vs. 1.4±0.6, P=.02). The group of women with axillary lymph node involvement and radiotherapy showed an overall and disease-free survival at 10 years similar to that obtained in patients without irradiation (89.7% and 77.2%, respectively). 3 lymph nodes involved multiplied by more than 7 times the risk of death (HR=7.20; 95% CI: 1.36 to 38.12). The multivariate analysis showed axillary lymph node dissection as the only variable associated with the development of lymphedema. The incidence of axillary relapse on stage I and II breast cancer is rare. In these patients axillary radiotherapy does not improve overall survival, but contributes to regional control in those patients with risk factors. Copyright © 2016 AEC.

    During drug treatment of tuberculous lymphadenitis, paradoxical response (PR) may occasionally occur. Continued treatment or lymph node aspiration improves PR without severe sequelae. However, we report a case of severe PR in a patient with cervical lymph node tuberculosis causing airway obstruction due to retropharyngeal lymph node swelling during antituberculous treatment. Tracheostomy and drainage of the node were performed to secure the airway. Possible airway obstruction due to PR must be suspected when cervical lymph node tuberculosis involves the retropharyngeal lymph node.

    Since 2007, one-step nucleic acid amplification (OSNA) has been used as a diagnostic system for sentinel lymph node (SLN) examination in patients with breast cancer. This study aimed to define a new clinical cut-off of CK19 mRNA copy number based on the calculation of the risk that an axillary lymph node dissection (ALND) will be positive. We analyzed 1529 SLNs from 1140 patients with the OSNA assay and 318 patients with positive SLNs for micrometastasis (250 copies) and macrometastasis (5000 copies) underwent ALND. Axillary non-SLNs were routinely examined. ROC curves and Youden's index were performed in order to identify a new cut-off value. Logistic regression models were performed in order to compare OSNA categorical variables created on the basis of our and traditional cut-off to better identify patients who really need an axillary dissection. 69% and 31% of OSNA positive patients had a negative and positive ALND, respectively. ROC analysis identified a cut-off of 2150 CK19 mRNA copies with 95% sensitivity and 51% specificity. Positive and negative predictive values of this new cut-off were 47% and 96%, respectively. Logistic regression models indicated that the cut-off of 2150 copies better discriminates patients with node negative or positive in comparison with the conventional OSNA cut-off (ppatients really need an ALND and which patients can avoid one. This is why we suggest that the negative cut-off should be raised from 250 to 2150. Furthermore, we propose that for patients with a copy number that ranges between 2150 and 5000, there should be a multidisciplinary discussion concerning the clinical and bio-morphological features of primary breast cancer before any decision is taken on whether to perform an ALND or not.

    Complete lymph node dissection (CLND) after a positive sentinel node (SN) biopsy provides important prognostic information in melanoma patients but has been questioned for therapeutic use recently. We explored whether quantification of the tumour spread to SNs may replace histopathology of non-sentinel nodes (NSNs) for staging purposes. We quantified melanoma spread in SNs and NSNs in 128 patients undergoing CLND for a positive SN. In addition to routine histopathology, one-half of each of all 1496 SNs and NSNs was disaggregated into a single cell suspension and stained immunocytochemically to determine the number of melanoma cells per 10 6 lymph node cells, i.e. the disseminated cancer cell density (DCCD). We uncovered melanoma spread to NSNs in the majority of patients; however, the tumour load and the proportion of positive nodes were significantly lower in NSNs than in SNs. The relation between SN and NSN spread could be described by a mathematical function with DCCD NSN  = DCCD SN c /10 1 - c (c = 0.69; 95% confidence interval [CI]: 0.62-0.76). At a median follow-up of 67 months, multivariable Cox regression analyses revealed that DCCD SN (p = 0.02; HR 1.34, 95% CI: 1.05-1.71) and the total number of pathologically positive nodes (p = 0.02; HR 1.53, 95% CI: 1.07-2.22) were significant risk factors after controlling for age, gender, thickness of melanoma and ulceration status. A prognostic model based on DCCD SN and melanoma thickness predicted outcome as accurately as a model including pathological information of both SNs and NSNs. The assessment of DCCD SN renders CLND for staging purposes unnecessary. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Background: We assessed the utility of enhanced magnetic resonance imaging (MRI) using ultrasmall superparamagnetic iron oxide (USPIO) in the evaluation of axillary lymph node metastases in patients with breast cancer. Study design: MR examination of the axilla was performed before and 24-36 h after USPIO administration for patients with stage II or III breast cancer. Diagnostic performance was compared using size criteria (metastasis was defined when short axis diameter >5 or >10 mm) or morphologic criteria on conventional MRI, the combined study of USPIO precontrast and postcontrast images, and USPIO postcontrast study alone. Results: A total of 622 nodes (503 metastatic and 119 nonmetastatic nodes) were dissected from 33 patients. The results of conventional MRI for nodes >5 mm were 59.1% sensitivity, 86.7% specificity, and 80.4% overall accuracy. Results for nodes >10 mm were 15.7% sensitivity, 99.2% specificity, and 80.2% overall accuracy. Results based on morphology were 36.5% sensitivity, 94.1% specificity, and 81.0% overall accuracy. The results of the combined study of USPIO precontrast and postcontrast images were 86.4% sensitivity, 97.5% specificity, 91.1% positive predictive value, 96.1% negative predictive value, and 95.0% overall accuracy. The results of USPIO postcontrast images alone were 84.7% sensitivity, 96.8% specificity, and 94.0% overall accuracy. Patient-based results of postcontrast USPIO study alone were 100.0% sensitivity, 80.0% specificity, and 93.9% overall accuracy. Conclusions: USPIO postcontrast study alone was useful in the assessment of axillary lymph node metastases in patients with breast cancer

    Full Text Available Kikuchi-Fujimoto disease, known as Kikuchi disease, is a rare benign and self-limiting disorder that typically affects the regional cervical lymph nodes. Generalized lymphadenopathy and extranodal involvement are rare. We report a rare case of a 19-yearold female with a history of persistent fever, nausea, and debilitating malaise. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT revealed multiple hypermetabolic generalized lymph nodes in the cervical, mediastinum, axillary, abdomen and pelvic regions with diffuse spleen, diffuse thyroid gland, and focal parotid involvement, bilaterally. In addition, subcutaneous lesions were noted in the left upper paraspinal and occipital regions. An excisional lymph node biopsy guided by 18F-FDG PET/CT revealed the patient’s diagnosis as Kikuchi syndrome.

    A common clinicopathological factor except for T stage that could significantly influence the clinical outcome of advanced node-negative gastric cancer patients following radical gastrectomy was unknown. This study was designed to investigate the clinicopathological characteristics of these patients, and to evaluate the outcome indicators and improve the risk stratification. A total of 195 patients harboring advanced gastric adenocarcinoma with no lymph node and distant metastases and following radical gastrectomy were retrospectively analyzed from the prospectively collected database of Zhongshan Hospital of Fudan University between 2006 and 2010. The 3-year and 5-year overall survival rates of this study population were 85.0 and 69.6%. Factors influencing the overall survival were the degree of tumor differentiation, the depth of invasion and the number of lymph nodes resected (LN, cutoff = 18). Lymph node was recognized as an independent prognostic factor for overall survival of advanced node-negative gastric cancer patients, and the prognosis of the patients with greater number of lymph nodes resected (LN ≥ 18) was significantly better than those with lymph node patients with T3/T4 stage could be significantly stratified by lymph node. Based on this condition, a new staging system named tumor-node-metastasis staging system for T3/T4 node-negative gastric cancer was constructed, which could have statistically different overall survival between subgroups. Lymph node was an independent prognostic factor of patients with advanced node-negative gastric cancer, and retrieval of more than 18 lymph nodes should be warranted. In addition, these patients with lesser number of lymph nodes resected might need aggressive postoperative treatment and closer follow-up. © The Author 2015. Published by Oxford University Press.

    Extracorporeal human lymphatic organs are expected to be excellent tools in the study of human molecular and cellular bases of the immunologic balance and tissue harmony. A rational approach and process to design a device and a procedure to recreate the human lymph node environment in vitro is described with emphasis on T-cell activation. Based on this approach, a bioreactor and a process supporting self-assembly of human lymphatic tissues due to proper emulation of human architecture and homeostasis could be developed.

    1997-11-01

    In a four-year-old male cat, a subcutaneous phyma about 3.5 cm in diameter was surgically removed from the left inframandibular region. Histopathologically, the phyma was found to be the swollen medial retropharyngeal lymph node containing an actinomycotic abscess. The filamentous organisms in the abscess stained positively by the Gram's, Grocott's and periodic acid-Schiff methods, and were negative by the Ziehl-Neelsen method. By the immunoperoxidase method, the organisms were specifically identified as Actinomyces viscosus serotype 2 by its antiserum absorbed with A. viscosus serotype 1 antigen.

    Full Text Available Background & objectives: Lymphadenopathy and haematological alterations are the earliest manifestations with other associated opportunistic infections and malignancies. Hence, there is a need for simple investigations like fine needle aspiration cytology (FNAC for evaluation of HIV lymphadenopathy and a haemogram to interpret the haematological alterations. This study was undertaken to analyze the cytological patterns of lymph node lesions in HIV/AIDS patients, to compare with available clinico-pathological and haematological parameters to segregate lymphadenopathy cases for further evaluation. Methods: In the present study, 129 HIV seropositive patients were included. Lymph node aspirates were stained routinely with hematoxylin and eosin and Ziehl-Neelsen (Z-N stains. Special stains and cultures were done in selected patients. Peripheral smears were taken from all the patients and CD4 counts were recorded. Tuberculous lymphadenitis was further categorized. Acid fast bacilli (AFB grading was done on Z-N positive smears. Each lesion was compared with CD4 counts, WHO clinical staging and haematological picture. Results: Cytological diagnosis in 129 patients included tuberculous (n=54, 41.9%, reactive lymphadenopathy (n=46, 35.6%, suppurative (n=16, 12.4% lymphadenitis, non-Hodgkin′s lymphoma (n=4, 3.1%, and Hodgkin′s lymphoma, secondary deposits, other granulomatous lesions, and cryptoccocal lymphadenitis in one patient each. The predominant cytomorphological pattern in tuberculous lymphadenitis was caseous necrosis + epithelioid granuloma formation (51.85%. Grade 2+ Z-N grading was noted in 62.96 per cent of AFB positive smears. CD4 counts showed a descending pattern with progression of WHO clinical staging. Cytopenia was more common in WHO clinical stage IV disease. Interpretation & conclusions: Lymph node cytology was found to be a useful tool for segregating lymphadenopathy cases for further evaluation and for identification of

    Purpose: To investigate if strain elastography could differentiate between metastatic and non-metastatic mesenteric lymph nodes ex-vivo. Materials and Methods: 90 mesenteric lymph nodes were examined shortly after resection from 25 patients including 17 patients with colorectal cancer and 8...... patients with Crohn's disease. Ultrasound-based strain elastography was performed with a linear probe. Tissue hardness in lymph nodes was assessed using visual scales and measuring the strain ratio. B-mode characteristics were also recorded. Pathological diagnosis with grading of fibrosis served...... non-metastatic nodes, but the difference was not significant (65.5 vs. 55.0, p = 0.055). There was no difference between lymph nodes in Crohn's and non-metastatic cancer specimens. The metastatic lymph nodes were significantly more fibrotic than the non-metastatic lymph nodes by the ordinal fibrosis...

    Accurate breast cancer staging is essential for optimal management of adjuvant therapies. While breast lymphatic drainage involves both axillary and internal mammary (IM) lymph node (LN) basins, IM LN sampling is not routinely advocated. The current study analyzes the incidence of IM LN metastases sampled during free flap breast reconstruction and subsequent changes in adjuvant treatment. A retrospective analysis of patients with positive IM LN biopsies during free flap breast reconstruction was performed. Pre-reconstruction surgical and adjuvant therapies as well as staging and prognostic data were recorded. Change in adjuvant therapies based solely on IM LN positivity was determined. IM LN metastases were found on 28 (1.3%) out of 2057 patients and comprised the study population. Mean age was 49 years with pre-reconstruction chemotherapy or radiation administered in 50 or 54% of cases, respectively. Five (18%) patients had previously undergone lumpectomy with axillary sampling. Mean tumor size was 3.1 cm with tumor location evenly distributed among all four quadrants. Ten (36%) patients had isolated IM LN metastases Patients with both axillary and IM disease had larger lesions, increased prevalence of pre-reconstruction chemotherapy and radiation. Based exclusively on positive IM LN disease, 17 (63%) patients had a change in adjuvant therapy. Despite the low incidence of IM LN metastases, IM LN biopsy during free flap breast reconstruction is recommended. In 36% of cases, nodal metastases were isolated to the IM nodes. Identification of IM metastases influenced adjuvant therapies in a majority of cases.

    Nodal staging is crucial in determining the use of adjuvant chemotherapy for colon cancer. The number of metastatic lymph nodes has been positively correlated with the number of lymph nodes examined. Current guidelines recommend that at minimum 12 to 14 lymph nodes be assessed. In some studies, mismatch repair deficiency has been associated with lymph node yield. The purpose of this work was to determine whether mismatch repair-deficient colorectal tumors are associated with increased lymph node yield. We queried an institutional database to analyze colectomy specimens with immunohistochemistry for mismatch repair genes in patients treated for colorectal cancer between 1999 and 2012. Before 2006, immunohistochemistry was performed at the request of an oncologist or surgeon. After 2006, it was routinely performed for patients mismatch repair deficiency. On univariate analysis, mismatch repair deficiency was associated with lower lymph node yield, older patient age, right-sided tumors, and poor differentiation. The linear regression model identified 5 variables with independent relationships to lymph node yield, including patient age, specimen length, lymph node ratio, perineural invasion, and tumor size. A positive correlation was observed with tumor size, specimen length, and perineural invasion. Tumor location had a more complex, nonlinear, quadratic relationship with lymph node yield; proximal tumors were associated with a higher yield than more distal lesions. Mismatch repair deficiency was not independently associated with lymph node yield. Mismatch repair immunohistochemistry based on patient age, family history, and pathologic features may reduce the generalizability of these results. Our sample size was too small to identify variables with small measures of effect. The retrospective nature of the study did not permit a true assessment of the extent of mesenteric resection. Patient age, length of bowel resected, lymph node ratio, perineural invasion, tumor

    Between January 1983 and December 1988, 218 female patients with known breast cancer and positive axillary nodes were treated with adjuvant radiotherapy and chemotherapy following radical mastectomy. Treatment results were retrospectively analysed at the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University of College of Medicine. The patients were classified into 3 groups; group 1 included 80 patients treated with adjuvant chemotherapy alone; in group 2, 52 patients treated with radiotherapy alone; and in group 3, 86 patients treated with combined chemo-radiotherapy. The mean age was 44 years and ranged from 27 to 70. The median follow-up time was 51 months. Seven-year relapse free and overall survival rates were 56% and 67%; in group 1, 50% and 56%; in group 2, 51% and 65%; and in group 3, 62% and 75% respectively. This difference was not statistically significant(p<0.05). The loco-regional failure rates were 13% and distant failure rates were 33%. There was less risk of loco-regional failure in group 2 and 3 which included radiotherapy (.0<0.05). But there was no significant y difference in the rates of distant failure(p>0.05). By univariate analysis, the only significant prognostic factor affecting relapse-free survival was the percentage of positive axillary nodes; and the overall survival significantly correlated with the primary tumor size, the number or percentage of positive axillary nodes, and stage. But in multivariate analysis, the only significant prognostic factor was treatment modality. By univariate analysis of prognostic factors affecting the rates of overall failure and distant failure, the significant prognostic factors was the percentage of positive axillary nodes; and the risk of the loco-regional failure significantly correlated with the treatment modality. In conclusion, these results suggest a potential for decreasing the risk of loco-regional failure with the addition of postoperative radiotherapy to chemotherapy in the

    Tolerance and efficiency of radiation therapy treatment of the pelvic lymph nodes were assessed in 122 patients with prostate cancer. With no severe observed late toxicity the incidence for lymph node metastases was between 3,0% (primarily irradiated patients without lymph node or distant metastases) and 100% (primarily irradiated patients with lymph node and distant metastases) after 3 years. As it seems, the following subgroups might possibly profit the most from a dose escalation in the pelvic lymph nodes: primarily irradiated patients with positive lymph nodes and postoperatively irradiated patients in adjuvant/additive situation, with a biochemical or a local/lymph node recurrence.

    Full Text Available Abstract Background Current practice is to perform a completion axillary lymph node dissection (ALND for breast cancer patients with tumor-involved sentinel lymph nodes (SLNs, although fewer than half will have non-sentinel node (NSLN metastasis. Our goal was to develop new models to quantify the risk of NSLN metastasis in SLN-positive patients and to compare predictive capabilities to another widely used model. Methods We constructed three models to predict NSLN status: recursive partitioning with receiver operating characteristic curves (RP-ROC, boosted Classification and Regression Trees (CART, and multivariate logistic regression (MLR informed by CART. Data were compiled from a multicenter Northern California and Oregon database of 784 patients who prospectively underwent SLN biopsy and completion ALND. We compared the predictive abilities of our best model and the Memorial Sloan-Kettering Breast Cancer Nomogram (Nomogram in our dataset and an independent dataset from Northwestern University. Results 285 patients had positive SLNs, of which 213 had known angiolymphatic invasion status and 171 had complete pathologic data including hormone receptor status. 264 (93% patients had limited SLN disease (micrometastasis, 70%, or isolated tumor cells, 23%. 101 (35% of all SLN-positive patients had tumor-involved NSLNs. Three variables (tumor size, angiolymphatic invasion, and SLN metastasis size predicted risk in all our models. RP-ROC and boosted CART stratified patients into four risk levels. MLR informed by CART was most accurate. Using two composite predictors calculated from three variables, MLR informed by CART was more accurate than the Nomogram computed using eight predictors. In our dataset, area under ROC curve (AUC was 0.83/0.85 for MLR (n = 213/n = 171 and 0.77 for Nomogram (n = 171. When applied to an independent dataset (n = 77, AUC was 0.74 for our model and 0.62 for Nomogram. The composite predictors in our model were the product of

    The morphology and location of lymph nodes from seven species of Odontocetes, of both sexes and different age groups, were described. All animals were derived from stranding events along the North and Northeastern coasts of Brazil. After the identification of lymph nodes in situ, tissue samples were analyzed for light and electron microscopy. Vascular volume density (VVD) and vascular length density (VLD) were evaluated in the mesenteric lymph nodes. Lymph nodes occurred as solitary nodules or in groups, varying in shape and size. In addition to using the nomenclature recommended by Nomina Anatomica Veterinaria, new nomenclatures were suggested based on the lymph nodes topography. Lymph nodes were covered by a highly vascularized and innervated capsule of dense connective tissue, below which muscle fibers were observed, inconsistently, in all studied species. There was no difference in VLD among different age groups. However, VVD was higher in adults. Lymph nodes parenchyma was divided into an outer cortex, containing lymph nodules and germinal centers; a paracortical region, transition zone with dense lymphoid tissue; and an inner medulla, composed of small irregular cords of lymphatic tissue, blood vessels, and diffuse lymphoid tissue. Abundant collagen fibers were observed around arteries and arterioles. Germinal centers were more evident and developed in calves and young animals, being more discrete and sparse in adults. The morphology of lymph nodes in Odontocetes was typical of that observed in other terrestrial mammals. However, new groups of lymph nodes were described for seven species occurring in the Brazilian coast. Copyright © 2014 Wiley Periodicals, Inc.

    Full Text Available "nBackground: Technetium-99m phytate (99mTc-ph is a readily available radiopharmaceutical and has been suggested as a suitable agent for sentinel lymph node (SLN detection. In this study, the diagnostic accuracy and false-negative rate of radionuclide SLN mapping using 99mTc-ph were investigated. "nMethods: Forty three women (mean age 52.3 years, range 31-74 years, who all had been diagnosed with breast cancer were enrolled in the study. All patients had no palpable axillary lymph nodes and had not undergone exploratory tumor resection or any drug treatment, previously. 99mTc-ph was injected peri-tumorally at four sites. Following SLN scintigraphic imaging, the patients were operated. Intraoperatively SLN were detected by a scintillation probe and a blue dye technique. Modified radical mastectomies with radical axillary dissection were performed with excision of the lymph nodes, to evaluate the accuracy of the SLN technique. "nResults: Intraoperative scinti-mapping identified SLN in 40 of the 43 patients (detection rate: 93%. Scintigraphically, none of the patients had internal mammary drainage or contralateral axillary involvement. The blue dye detection rate in 23 patients under study was 87% and all lymph nodes detected by the blue dye technique were also detected as "hot" spots in the lymphoscintigraphy. Using pathology as the gold standard, the sensitivity and negative predictive value of scintigraphic lymphatic mapping in detection of SLN by 99mTc-ph were 90% and 90.9%, respectively. The same values for blue dye lymphatic mapping were 84.6% and 77.7%, respectively. "nConclusion: 99mTc-ph used for SLN mapping is readily available, has low cost and gives better results than the blue dye technique. Long-term follow-up is required to assess accurately the incidence of failure in patients with negative SLN and the overall diagnostic accuracy and efficacy of the SLN mapping using 99mTc-ph as the radioactive tracer.

    Sentinel lymph nodes (SLN) in popliteal basins are rare, and there is controversy in literature regarding their origin, management, and outcomes. To correlate clinical and pathological features of popliteal basin drainage and analyze the impact of popliteal lymph node drainage on survival. Retrospective analysis of SLN biopsies performed at a single institution between 2000 and 2010. SLN biopsies were performed in 254 patients with melanoma in lower limbs, 247 of which were evaluated. In this group, there were 59 patients (24%) with a positive SLN. Twenty-seven cases (11%) presented with popliteal drainage, one of which lacked concurrent groin drainage. Among these 27 patients, three (11%) had popliteal metastasis, one of which had exclusive involvement of this basin. Popliteal drainage was associated with worse 5-year disease-free survival (DFS) (P = 0.028) but not 5-year overall survival (OS) (P = 0.219) in univariate analysis. In multivariate analysis, Breslow thickness, mitotic index, and positive SLN were prognostic factors for DFS. Only mitotic index correlated significantly with OS (P = 0.044). Popliteal drainage seems to be associated with worse prognostic features of the primary tumor. © 2015 Wiley Periodicals, Inc.

    RANK and its ligand RANKL play important roles in the development and regulation of the immune system. We show that mice transgenic for Rank in hair follicles display massive postnatal growth of skin-draining lymph nodes. The proportions of hematopoietic and nonhematopoietic stromal cells and their organization are maintained, with the exception of an increase in B cell follicles. The hematopoietic cells are not activated and respond to immunization by foreign Ag and adjuvant. We demonstrate that soluble RANKL is overproduced from the transgenic hair follicles and that its neutralization normalizes lymph node size, inclusive area, and numbers of B cell follicles. Reticular fibroblastic and vascular stromal cells, important for secondary lymphoid organ formation and organization, express RANK and undergo hyperproliferation, which is abrogated by RANKL neutralization. In addition, they express higher levels of CXCL13 and CCL19 chemokines, as well as MAdCAM-1 and VCAM-1 cell-adhesion molecules. These findings highlight the importance of tissue-derived cues for secondary lymphoid organ homeostasis and identify RANKL as a key molecule for controlling the plasticity of the immune system.

    Full Text Available Background. Tuberculosis lymphadenitis is one of the most common forms of all extrapulmonary tuberculosis. Objective. To evaluate the magnitude of M. tuberculosis from lymph node biopsy paraffin-embedded sections among suspected patients visiting the Jimma University Specialized Hospital. Method. A cross-sectional study design of histological examination among lymph node biopsy paraffin-embedded sections by Ziehl-Neelsen and hematoxylin/eosin staining technique was conducted from December, 2009, to October, 2010, at the Department of Medical Laboratory Science and Pathology. Result. Histopathological examination of the specimens by hematoxylin and eosin staining technique revealed the presence of granulomas. But for the caseation and necrosis they were present in 85% cases of nodal tissue biopsies. From those, 56.7% were from females. The presence of acid-fast bacilli was microscopically confirmed by ZN staining in 37 (61.7% of the nodal tissue biopsies. Conclusion and Recommendation. Tuberculosis lymphadenitis is significantly more common in females. Hence, attention should be given for control and prevention of extrapulmonary tuberculosis.

    We retrospectively evaluated 41 patients with metastatic cervical tumors from unknown primary sites at the Hyogo College of Medicine between 1997 and 2007. The N stage classification of cervical lymph nodes was: N1 in 3 cases, N2a in 10 cases, N2b in 10 cases, N2c in 4 cases, and N3 in 14 cases. The histopathological diagnoses of cervical lymph node were: squamous cell carcinoma in 33 cases, adenocarcinoma in 5 cases, undifferentiated carcinoma in 2 cases, and papillary carcinoma in 1 cases. Primary tumor sites were: tonsil in 5 cases, esophaguses in 2 cases, hypopharynxies in 2 cases, and thyroid, oral floor, submandibular gland, lung, gastric and colon in 1 case each. The useful tests were gastric endoscope, positron emission tomography-computed tomography (PET-CT), and blind biopsy of tonsil. We treated 24 of the 41 patients. Therapies were: neck dissection with postoperative radiation therapy in 11 cases, neck dissection alone in 1 case, only radiation or chemoradiation therapy alone in 8 cases, and chemotherapy alone in 4 cases. The 5-year survival rate was 40.1% in all cases and 81.5% in cases who underwent neck dissection. (author)

    Full Text Available Reducing the long-term morbidity in testicular cancer survivors represents a major area of interest. External beam radiation therapy and systemic chemotherapy are established treatments for seminoma; however, they are associated with late toxicities such as cardiovascular disease, insulin resistance, and secondary malignancy. Retroperitoneal lymph node dissection (RPLND is a standard treatment for nonseminomatous germ cell tumors (NSGCT that has minimal long-term morbidity. Given the efficacy of RPLND in management of NSGCT, interest has developed in this surgery as a front-line treatment for seminoma with isolated lymph node metastasis to the retroperitoneum. Four retrospective studies have shown promising results when surgery is performed for seminomas with low-volume retroperitoneal metastases. To better determine if RPLND can be recommended as a primary treatment option, two prospective clinical trials (SEMS and PRIMETEST are underway. This review will examine the literature, discuss the benefits/limitations of RPLND, and compare the methodologies of the two ongoing clinical trials.

    Malignant melanoma initially metastasises to regional lymph nodes and belongs to the ''leading candidates'' for sentinel lymph node (SLN) management. In newly diagnosed melanoma stage Ib to IIIa, today the SLN diagnostics is classified as the staging method of first choice. The technique of the SLN diagnostics is described thoroughly, including multimodal imaging if this is required for selective SLN biopsy. The evaluation of the diagnostic results, documentation and classification encompasses an important part. In approximately 2/3 of the melanoma patients there is no presence of metastases in SLN and non-SLN, one of five patients has metastases in SLN with negative non-SLN, every sixth to tenth patient has positive SLN and non SLN. Every thirtieth patient with tumour free SLN exhibits pathological findings in the non-SLN by using conventional examination methods only, every fifteenth if using molecular-genetic methods in addition. Among the prognostic parameters the SLN status has the most significant impact on disease-free and disease-specific survival. (orig.)

    Purpose: To develop an automated system for mediastinal lymph node detection and station mapping for chest CT. Methods: The contextual organs, trachea, lungs, and spine are first automatically identified to locate the region of interest (ROI) (mediastinum). The authors employ shape features derived from Hessian analysis, local object scale, and circular transformation that are computed per voxel in the ROI. Eight more anatomical structures are simultaneously segmented by multiatlas label fusion. Spatial priors are defined as the relative multidimensional distance vectors corresponding to each structure. Intensity, shape, and spatial prior features are integrated and parsed by a random forest classifier for lymph node detection. The detected candidates are then segmented by the following curve evolution process. Texture features are computed on the segmented lymph nodes and a support vector machine committee is used for final classification. For lymph node station labeling, based on the segmentation results of the above anatomical structures, the textual definitions of mediastinal lymph node map according to the International Association for the Study of Lung Cancer are converted into patient-specific color-coded CT image, where the lymph node station can be automatically assigned for each detected node. Results: The chest CT volumes from 70 patients with 316 enlarged mediastinal lymph nodes are used for validation. For lymph node detection, their system achieves 88% sensitivity at eight false positives per patient. For lymph node station labeling, 84.5% of lymph nodes are correctly assigned to their stations. Conclusions: Multiple-channel shape, intensity, and spatial prior features aggregated by a random forest classifier improve mediastinal lymph node detection on chest CT. Using the location information of segmented anatomic structures from the multiatlas formulation enables accurate identification of lymph node stations.

    To study normal mediastinal and hilar lymph nodes on multi-detector chest computed tomography (CT). A cohort of 120 children aged 1-17 years underwent emergency CT, including the chest, after high-energy trauma. Axial 5-mm reconstructions were evaluated for lymph nodes at hilar and various mediastinal levels and the short-axis diameters were measured. At least one lymph node was found in 115 (96%) children, with subcarinal (69%), lower paratracheal (64%) and hilar (60%) nodes being most common. Up to 10 years of age most lymph nodes were smaller than or equal to 7 mm. In older children lymph nodes measuring up to 10-mm-short-axis diameter were found. Lymph nodes were rare along the mammary vessels, at lower oesophageal and at prevascular and posterior mediastinal levels in children. Mediastinal and hilar lymph nodes are more common than previously thought, probably because of increased detection by modern multi-detector CT. Lymph node location and age have to be taken into account when evaluating lymph nodes in the paediatric chest. (orig.)

    The presence of nodal metastases in rectal cancer plays an important role in accurate staging and prognosis, which depends on adequate lymph node harvest. The aim of this prospective study is to investigate the feasibility and survival benefit of improving lymph node harvest by a modified method with methylene blue injection in rectal cancer specimens. One hundred and thirty-one patients with rectal cancer were randomly assigned to the control group in which lymph nodes were harvested by palpation and sight, or to the methylene blue group using a modified method of injection into the superior rectal artery with methylene blue. Analysis of clinicopathologic records, including a long-term follow-up, was performed. In the methylene blue group, 678 lymph nodes were harvested by simple palpation and sight. Methylene blue injection added 853 lymph nodes to the total harvest as well as 32 additional metastatic lymph nodes, causing a shift to node-positive stage in four patients. The average number of lymph nodes harvested was 11.7 ± 3.4 in the control group and 23.2 ± 4.7 in the methylene blue group, respectively. The harvest of small lymph nodes (rectal cancer, especially small node and metastatic node retrieval, which provided more accurate staging. However, it was not associated with overall survival. © 2014 Royal Australasian College of Surgeons.

    Full Text Available Metastatic involvement of central lymph nodes in patients with papillary thyroid cancer (PTC is very common. However, prophylactic central lymph nodes dissection additionally to thyroidectomy does not significantly affect disease-free and overall survival of PTC patients. Meanwhile its routine conduction is tangibly increase postsurgical complications. From efficacy/safety point of view prophylactic central lymph nodes dissection couldn't be recommended as substantiated in all PTC patients.

    Objective: To study the CT appearance of the hilar and mediastinal enlarged lymph nodes in coal worker's pneumoconiosis (CWP), its pathological basis and diagnostic value for CWR complicated with lung cancer. Methods: (1) Twelve isolated lungs with CWP obtained at autopsy were inflated and fixed. CT scan was performed. The pathologic findings of enlarged lymph nodes were identified. (2) CT findings of hilar and mediastinal enlarged lymph nodes of 71 cases with CWP and 22 cases of CWP complicated with lung cancer were analyzed. Results: (1) Most of the enlarged hilar and mediastinal lymph nodes in simple CWR was in third stage of fibrosis. The fourth stage of fibrosis was only seen in lymph nodes of a case with complicated CWP. In this case the necrotic materials of lymph nodes eroded adjacent bronchi and vessels, and coalesced with progressive massive fibrosis (PMF). (2) The average number of lymph nodes in cases of complicated CWP was more than that of simple CWP (P 2 cm was 7.4%. (3) The prevalence of lymph nodes calcification in CWP was 61.1%, but egg shell calcification was only 14.7%. (4) In the cases of CWP complicated with lung cancer, lymph node > 2 cm was 20.8%, that was more than CWP (P 3 cm was 7.6%. Conclusion: Lymph nodes up to 1 cm may have dust fibrosis and coal silicosis nodules. The lymph nodes >2 cm is more common in CWP complicated with lung cancer than in simple CWP. The lymph nodes > 3 cm indicates higher probability of CWP with lung cancer than PMF

    Full Text Available Lymph node status remains one of the most useful prognostic indicators in breast cancer; however, current methods to assess nodal status disrupt the lymphatic system and may lead to secondary complications. Identification of molecular signatures discriminating lymph node-positive from lymph node-negative primary tumors would allow for stratification of patients requiring surgical assesment of lymph nodes. Primary breast tumors from women with negative (=41 and positive (=35 lymph node status matched for possible confounding factors were subjected to laser microdissection and gene expression data generated. Although ANOVA analysis (1.5 revealed 13 differentially expressed genes, hierarchical clustering classified 90% of node-negative but only 66% of node-positive tumors correctly. The inability to derive molecular profiles of metastasis in primary tumors may reflect tumor heterogeneity, paucity of cells within the primary tumor with metastatic potential, influence of the microenvironment, or inherited host susceptibility to metastasis.

    The purpose of this study was to determine the optimal cut-off value of lymph node size for diagnosing metastasis in gastric cancer with multidetector-row computed tomography (MDCT) after categorizing perigastric lymph nodes into three regions. The study included 90 gastric cancer patients who underwent gastrectomy. The long-axis diameter (LAD) and short-axis diameter (SAD) of all visualized lymph nodes were measured with transverse MDCT images. The locations of lymph nodes were categorized into three regions: lesser curvature, greater curvature, and suprapancreatic. The diagnostic value of lymph node metastasis was assessed with receiver operating characteristic (ROC) analysis. The area under the curve was larger for SAD than LAD in all groups. The optimal cut-off values of SAD were determined as follows: overall, 9 mm; differentiated type, 9 mm; undifferentiated type, 8 mm; lesser curvature region, 7 mm; greater curvature region, 6 mm; and suprapancreatic region, 9 mm. The diagnostic accuracies for lymph node metastasis using individual cut-off values were 71.1 % based on histological type and 76.6 % based on region of lymph node location. The diagnostic accuracy of lymph node metastasis in gastric cancer was improved by using individual cut-off values for each lymph node region. (orig.)

    To diagnose diffuse large B-cell lymphosarcoma (DLBCLS) with primary involvement of the mediastinal lymph nodes (LN) and to evaluate the efficiency of aggressive polychemotherapy (PCT). The study included 15 patients (6 men and 9 women aged 18 to 70 years; median 38 years) followed up at the Hematology Research Center, Russian Academy of Medical Sciences, in 2004 to 2009. Three and 12 patients had Stages II and IE DLBCLS, respectively. B symptoms were found in 14 (93.4%) patients. Increased lactate dehydrogenase (LDH) concentrations were detectable in 14 (93.4%) patients; tumors of 10 cm or more (bulky disease) were seen in 11 (73.3%). Enlarged cervical, supraclavicular, and axillary lymph nodes were found in 9 (60%) patients; lung involvement via extension in 9 (60%), and invasion into the pericardium in 5 (33.3%) and soft tissues of the anterior thoracic wall in (13.3%). There were no signs of involvement of extranodal organs at the moment of diagnosis. All the 15 patients received PCT according to the modified NHL-BFM-90 program: 4 to 6 courses depending on the response to the therapy; 10 (66.6%) and 5 (33.3%) patients had 4 and 6 courses, respectively; for consolidating purpose, 11 (78.5%) patients were prescribed radiotherapy applied to the mediastinum in a cumulative dose of 36 Gy due to the fact that they had a residual mass. Thirteen (86.6%) patients achieved a complete remission (CR). Primary PCT resistance was confirmed in one case. Another patient was stated to have near-complete remission. No recurrences were notified during the follow-up. The mean CR duration was 24.5 (range 2-49) months. DLBCLS with primary LN involvement is an individual nosological entity to be differentiated from primary mediastinal large B-cell lymphosarcoma. In most cases, DLBCLS shows signs of a poor prognosis, which makes it necessary to perform aggressive PCT.

    The authors assessed the mycobacterial lesions in the lymph nodes discovered on tissue samples coming from the surgical stage in the Department of Pathology, Emergency County Hospital of Craiova, Romania, starting from 1990 until 2012. The studied material consisted of lymph node (LN) tissue samples obtained by biopsy or surgical excision from 362 patients histopathologically diagnosed with tuberculosis. For confirming the diagnosis, Ziehl-Neelsen staining was carried out and, in some cases, PCR technique was used. Patients were mainly women, with a mean age of 35 years. The suspicion of diagnosis at admission was reduced, the most usual diagnosis being a very general and uncertain one of "adenopathy/polyadenopathy". In only few cases, other tissues/organs have been affected in the same time with the LN determination. Also, multiple LN group involvement was present in only five cases. The most affected LN groups were: the lateral cervical, submandibular, axillary, inguinal, supraclavicular and mesenteric. In paired LN groups, there was no predilection for any of the body sides. Epithelioid cells (ECs) and giant Langhans cells (GLCs) were present together in most of the granulomatous reactions. However, the presence of neutrophils in 10% of the cases should be noticed. Necrosis was present in almost all cases, displaying the whole range of morphological features, but usually the acidophilic, microgranular one. Fibrosis was rarely encountered. As a whole, well-differentiated granulomas were the most frequent but the presence of hyporeactive granulomas in more than a quarter of the cases and that of non-reactive granulomas in more than 10% of the cases should be noticed. The extension of TB process was not a rare event. LNs seem to be the favorite location of TB besides the lung. The overall morphological picture revealed an active and destructive profile of the bacillary aggression in the LN parenchyma, which could mean either a higher sensitivity of the LN tissue or

    Full Text Available Lymph node metastasis indicates poor prognosis in esophageal cancer. To understand the underlying mechanisms, most studies so far focused on investigating the tumors themselves and/or invaded lymph nodes. However they neglected the potential events within the metastatic niche, which precede invasion. Here we report the first description of these regulations in patients on transcription level. We determined transcriptomic profiles of still metastasis-free regional lymph nodes for two patient groups: patients classified as pN1 (n = 9, metastatic nodes exist or pN0 (n = 5, no metastatic nodes exist. All investigated lymph nodes, also those from pN1 patients, were still metastasis-free. The results show that regional lymph nodes of pN1 patients differ decisively from those of pN0 patients--even before metastasis has taken place. In the pN0 group distinct immune response patterns were observed. In contrast, lymph nodes of the pN1 group exhibited a clear profile of reduced immune response and reduced proliferation, but increased apoptosis, enhanced hypoplasia and morphological conversion processes. DKK1 was the most significant gene associated with the molecular mechanisms taking place in lymph nodes of patients suffering from metastasis (pN1. We assume that the two molecular profiles observed constitute different stages of a progressive disease. Finally we suggest that DKK1 might play an important role within the mechanisms leading to lymph node metastasis.

    To determine the association between lymph node size and metastasis and to assess measurement of lymph node size as an accurate and reliable means of tumor staging in dogs with oral malignant melanoma. Retrospective study. 100 dogs with histologically confirmed oral malignant melanoma. Clinical records for dogs with oral malignant melanoma were reviewed. Data regarding size and results of cytologic or histologic examination of lymph nodes were evaluated. The association between lymph node size and metastasis was determined. Forty-seven (47%) dogs, of which 23 (49%) had enlarged mandibular lymph nodes, had no cytologic or histologic evidence of metastasis. Of 53 (53%) dogs with cytologic or histologic evidence of mandibular lymph node metastasis, 37 (70%) had enlarged mandibular lymph nodes, and 16 (30%) had mandibular lymph nodes of normal size. Overall, 16 of the 40 (40%) dogs with normal-sized lymph nodes had microscopic evidence of metastatic disease. Sensitivity and specificity of lymph node size as a predictor of metastasis were 70 and 51%, respectively, and the positive and negative predictive values were 62 and 60%, respectively. Although a significant relationship was identified between lymph node size and metastasis to the lymph node, this association did not appear strong enough to be clinically relevant. Results suggest that lymph node size alone is insufficient for accurate clinical staging of oral malignant melanoma in dogs; cytologic or histologic examination of regional lymph nodes should routinely be performed, regardless of size of those nodes.

    The lymphatic vascular system exerts major physiological functions in the transport of interstitial fluid from peripheral tissues back to the blood circulation and in the trafficking of immune cells to lymph nodes. Previous studies in global constitutive knockout mice for the lymphatic transmembrane molecule podoplanin reported perinatal lethality and a complex phenotype with lung abnormalities, cardiac defects, lymphedema, blood-filled lymphatic vessels, and lack of lymph node organization, reflecting the importance of podoplanin expression not only by the lymphatic endothelium but also by a variety of nonendothelial cell types. Therefore, we aimed to dissect the specific role of podoplanin expressed by adult lymphatic vessels. We generated an inducible, lymphatic-specific podoplanin knockout mouse model (Pdpn ΔLEC ) and induced gene deletion postnatally. Pdpn ΔLEC mice were viable, and their lymphatic vessels appeared morphologically normal with unaltered fluid drainage function. Intriguingly, Pdpn ΔLEC mice had blood-filled lymph nodes and vessels, most frequently in the neck and axillary region, and displayed a blood-filled thoracic duct, suggestive of retrograde filling of blood from the blood circulation into the lymphatic system. Histological and fluorescence-activated cell sorter analyses revealed normal lymph node organization with the presence of erythrocytes within lymph node lymphatic vessels but not surrounding high endothelial venules. Moreover, fluorescein isothiocyanate painting experiments revealed reduced dendritic cell migration to lymph nodes in Pdpn ΔLEC mice. These results reveal an important role of podoplanin expressed by lymphatic vessels in preventing postnatal blood filling of the lymphatic vascular system and in contributing to efficient dendritic cell migration to the lymph nodes. © 2016 American Heart Association, Inc.

    2015-01-01

    The initiation of adaptive immune responses depends upon the careful maneuvering of lymphocytes and antigen into and within strategically placed lymph nodes (LNs). Non-hematopoietic stromal cells form the cellular infrastructure that directs this process. Once regarded as merely structural features of lymphoid tissues, these cells are now appreciated as essential regulators of immune cell trafficking, fluid flow, and LN homeostasis. Recent advances in the identification and in vivo targeting of specific stromal populations have resulted in striking new insights to the function of stromal cells and reveal a level of complexity previously unrealized. We discuss here recent discoveries that highlight the pivotal role that stromal cells play in orchestrating immune cell homeostasis and adaptive immunity. Copyright © 2014 Elsevier Ltd.

    Purpose Exosomes are cell derived extracellular nanovesicles that relay molecular signals pertinent to both normal physiologic and disease processes. The ability to modify and track exosomes in vivo is essential to understanding exosome pathogenesis, and for utilizing exosomes as effective diagnostic and therapeutic nanocarriers to treat diseases. Methods We recently reported a new electroporation method that allow exosomes to be loaded with superparamagnetic iron oxide nanoparticles for magnetic resonance tracking. Results Building on this approach, we now demonstrate for the first time using a C57BL/6 mouse model that melanoma exosomes can be imaged in vitro, and within lymph nodes in vivo with the use of standard MRI approaches. Conclusion These findings demonstrate proof of principle that exosome biology can be followed in vivo and pave the way for the development of future diagnostic and therapeutic applications.

    Lymph node tuberculosis (LNTB) is the most frequent form of extra-pulmonary tuberculosis (TB). Randomised, controlled trials have convincingly demonstrated that 6 months of chemotherapy is sufficient for most drug-susceptible LNTB. We performed a retrospective, multicentric study from 1997 to 2010 to describe factors associated with prolonged anti-tuberculosis treatment in patients with LNTB. Of 126 patients diagnosed with LNTB, 22 (17.5%) were human immunodeficiency virus (HIV) infected. The median treatment duration was 9 months (interquartile range, 6-12). Treatment was significantly longer in patients with HIV (P < 0.01), additional sites of TB (P < 0.01) or weight loss (P = 0.04). Factors independently associated with excessively lengthy treatment were HIV co-infection and the presence of other TB foci.

    BACKGROUND: Extensive pathological workup of sentinel lymph nodes (SLNs) in melanoma detects more patients with metastasis-positive SLNs than do routine protocols, but at the cost of high laboratory workloads. We aimed to design a protocol that reduced this workload without compromising metastasis...... detection. METHODS: We analyzed 920 SLNs from 321 consecutive patients with melanoma by complete step sectioning and immunohistochemistry. We designed different models to theoretically reduce the number of histological sections examined and compared the results from these simulations with results obtained...... with our extended protocol, with the restricted national Danish protocol, and with the protocol recommended by the European Organization for Research and Treatment of Cancer (EORTC). RESULTS: The extended protocol increased the metastasis detection rate by 22% (95% confidence interval, 11-34; 30.8% vs. 25...

    2018-02-01

    Full Text Available Cancer patients with lymph node (LN metastases have a worse prognosis than those without nodal disease. However, why LN metastases correlate with reduced patient survival is poorly understood. Recent findings provide insight into mechanisms underlying tumor growth in LNs. Tumor cells and their secreted molecules engage stromal, myeloid, and lymphoid cells within primary tumors and in the lymphatic system, decreasing antitumor immunity and promoting tumor growth. Understanding the mechanisms of cancer survival and growth in LNs is key to designing effective therapy for the eradication of LN metastases. In addition, uncovering the implications of LN metastasis for systemic tumor burden will inform treatment decisions.

    Sentinel lymph node (SLN) mapping is being adapted to gynecologic cancer. Higher SLN mapping rates were reported with indocyanine green (ICG) compared to other dyes. The aim of this film is to share our experience of SLN mapping with ICG in vaginal cancer. A 40 year-old woman was diagnosed with squamous cell vaginal cancer. About 1.5 cm-sized tumor was located on the posterior vaginal fornix. Preoperatively she was assumed to be stage I vaginal cancer. Beginning of surgery, we performed SLN mapping by ICG injection into 3- and 9-o'clock positions of the vaginal tumor. Concentrated in 1.25 mg/mL, 1 mL of ICG solution was injected into deep stroma and another 1 mL submucosally in both sides. Bilateral SLN identification and lymphadenectomy were done. Afterward, laparoscopic Type C1 Querleu-Morrow radical hysterectomy with vaginectomy was done. A fluorescence endoscope produced by KARL STORZ (Tuttlingen, Germany) was used for ICG detection. To our knowledge, this is the first film report performing SLN mapping with ICG in vaginal cancer. The mapping was successful and we were able to recognize SLN of vaginal cancer. SLNs were located in the bilateral obturator fossa. According to the pathologic diagnosis, the mass size was 15 mm and invasion depth was 1 mm. Subvaginal tissue involvement and pelvic wall extension were absent. Resection margin of the vagina was free from carcinoma. No lymph node metastasis was reported including the bilateral SLNs. For vaginal cancer, SLN mapping can be applied by injecting ICG into the bilateral sides of the vaginal tumor. Copyright © 2017.

    Background and Purpose: The most commonly used approach for the assessment for differentiating malignant versus reactive lymph nodes is the measurement of the cross-section diameter of the lymph nodes in the transversal CT-planes. The intention of this article is to assess the impact of varying definitions of pathological lymph node size in CT-imaging in patients with Hodgkin lymphoma and to evaluate its effect on staging, chemotherapy regimes and radiation field size. Materials and methods: Pretherapeutic CT-scans of 10 consecutive patients with Hodgkin lymphoma have been evaluated based on two different definitions for malignant lymph node size; the classification of the German study group for Hodgkin lymphoma (1.0 cm) and the classification according to the results of the Cotswold consensus meeting 1989 (1.5 cm). Results: Applying the definitions of the DHSG and the Cotswold meeting we found more affected lymph node regions compared to the evaluation of the referring institutions in 9/10 and 6/10 patients, higher stages in 2/10 and 1/10 patients, more intense chemotherapy regimes in 3/10 and 1/10 and larger radiation fields in 10/10 and 6/10 patients, respectively. Conclusions: Varying definitions of pathologic lymph node size and inconsequent application of definitions reduce the comparability between different studies and within each study

    Although there is a lack of established survival benefit of sentinel lymph node biopsy (SLNB), this technique has been increasingly applied in the staging of patients with thin (≤1.00 mm) melanoma (T1Nx), without clear supportive evidence. We review the guidelines and available literature on the indications and rationale for performing SLNB in thin melanoma. As a consequence of the paucity of evidence of SLNB in thin melanoma, there is considerable variability in the guidelines. It is difficult to define clinicopathologic factors that reliably predict the presence of nodal metastasis. SLNB does not yet inform management in thin melanoma to improve survival outcome. Based on available evidence, high risk patients with melanomas between 0.75 and 1.00 mm may be appropriate candidates to be considered for SLN biopsy after discussing the likelihood of finding evidence of nodal progression, the risks of sentinel node biopsy, and the lack of proven survival benefit from any form of surgical nodal staging.

    Larger breast tumors tend to be associated with a greater number of axillary lymph nodes involved with metastatic tumor than are smaller tumors. This rule may not fully apply in BRCA1-related breast cancers. We hypothesized that the rule also might not apply in basal-like breast cancers (BLBC), and further, that disruption of this relationship would impact on prognosis. In 1,324 non-BLBC (87.1% of 1520 tumors), after adjustment for grade, a strongly positive correlation between increasing tumor size and increasing number of lymph nodes involved by tumor was observed (P for trend nodes" relationship in BLBC is distinct and is similar to that seen in BRCA1-related breast cancer, further suggesting biological similarities between these sub-types of breast cancer. Moreover, tumor size is not a strong indicator of prognosis in BLBC.

    Purpose: To assess the efficacy of MR imaging in the detection of lymph node metastasis in patients with no palpable lymph nodes ('N 0 neck') who have squamous cell carcinoma of the head and neck region. Material and Methods: MR neck imagings in 18 patients who underwent neck dissection (bilaterally in 2) for squamous cell carcinoma of the head and neck region were examined preoperatively for the purpose of detecting lymph node metastases. The imaging features taken into consideration were: size (cutoff point 10 mm), grouping, presence of central necrosis, and appearance of extracapsular spread. The MR examinations comprised spin-echo T1- and T2-weighted sequences. The MR findings were compared with those of surgery and histopathological examination. Results: MR suggested metastatic lymph node involvement in 5 necks. In 2 of these, central necrosis was seen in the enlarged lymph nodes. In a third, a grouping of the lymph nodes was noted. Extracapsular spread was not present. Histopathological examination revealed metastatic lymph nodes in 7 of 20 necks, the rate of clinically occult disease being 35%, and 4 of then had been accurately graded by MR. There was one false-positive MR examination. The MR sensitivity was 57.1% and specificity 92.3%. Conclusion: MR may reveal metastatic lymph nodes in patients with no clinical evidence of metastasis. However, conventional MR techniques are not always sufficient for decision-making on surgery in cases of 'N 0 neck'. (orig.)

    The varied behaviour of tuberculous lymph nodes during TB chemotherapy can cause clinical uncertainty, resulting in prolonged courses of treatment. To investigate whether results in routine practice in Blackburn, a high-incidence tuberculosis (TB) area in England and Wales, replicated the results of the 6-month chemotherapy trial for lymph node TB conducted by the British Thoracic Society. All TB cases managed at the Blackburn Chest Clinic are recorded prospectively. Patients with lymph node TB were identified over a 10-year period. A total of 100 patients with lymph node TB were listed in the database. Fine-needle aspiration was performed in 49 patients, while 66 underwent incisional lymph node biopsy. Culture confirmation was achieved in 60 cases. Sinus and new lymph node development was comparable between our study and the BTS trial. After cessation of treatment, 10 patients developed new/enlarged lymph nodes, but further investigations revealed that only three patients had relapsed TB. The varied behaviour of lymph node TB during and after treatment causes clinical uncertainty. Six months of chemotherapy is effective for fully susceptible TB in routine clinical practice in England. Investigation of new signs is important in differentiating patients with relapsed TB from normal varied behaviour.

    Regional lymph node metastases in colorectal cancer (CRC) decrease outcome. Whether nodal metastases function as a biomarker, i.e. as a sign of advanced disease, or are in fact involved in the metastatic process is unclear. We evaluated metastatic patterns of CRC according to the lymph node status of the primary tumor. A retrospective review of 1393 patients with metastatic CRC who underwent autopsy in the Netherlands was performed. Metastatic patterns of regional lymph node positive and negative CRC were compared and validated by population-based data from the Eindhoven Cancer Registry (ECR). Patients with regional lymph node positive CRC more often developed peritoneal metastases (28% vs. 21%, p=0.003) and distant lymph node metastases (25% vs. 15%, p <0.001). Incidences of liver and lung metastases were comparable. Data from the ECR confirmed our findings regarding peritoneal (22.4% vs. 17.0%, p=0.003) and distant lymph node metastases (15.8% vs. 9.7%, p <0.001). Regional lymph node positive CRC show a slightly different dissemination pattern, with higher rates of peritoneal and distant lymph nodes metastases. Comparable incidences of liver and lung metastases support the hypothesis that dissemination to distant organs occurs independently of lymphatic spread. PMID:27145371

    Full Text Available Introduction: Sentinel node biopsy is the gold standard for axillary assessment of patients with breast cancer without axillary metastases on clinical and radiological examination. Internationally accepted biopsy methods currently use a radioactive tracer (Te or different variations of vital stain, or the combination of the two. Due to the high cost of technical and organizational difficulty related to the radioactive material, as well as the disadvantages of using the vital stain method, great effort is being made to find alternative solutions. The aim of this study was to determine the effectiveness of the exclusive use of vital stain versus the radioactive isotope, and the need to use the combined method. A second goal was the comparative analysis of the radioactive method and intraoperative assessment of suspicious (non-sentinel lymph nodes.

    We evaluated the failure pattern of the celiac axis, gastric lymph node, and treatment outcome in the upper and mid-esophageal region of cancer patients treated by definitive radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, retrospectively. Materials and Methods: The study constituted the evaluation 108 patients with locally advanced esophageal cancer receiving radiotherapy or a combination of radiotherapy and chemotherapy at Chonbuk National University Hospital from January 1986 to December 2006. In total, 82 patients treated by planned radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, were analysed retrospectively. The study population consisted of 78 men and 2 women (mean age of 63.2 years). In addition, 51 patients received radiotherapy alone, whereas 31 patients received a combination of radiation therapy and chemotherapy. The primary cancer sites were located in the upper portion (17 patients), and mid portion (65 patients), respectively. Further, the patients were in various clinical stages including T1N0-1M0 (7 patients), T2N0-1M0 (18 patients), T3N0-1M0 (44 patients) and T4N0-1M0 (13 patients). The mean follow up period was 15 months. Results: The various treatment outcomes included complete response (48 patients), partial response (31 patients) and no response (3 patients). The failure patterns of the lymph node were comprised of the regional lymph node (23 patients) and the distance lymph node which included celiac axis and gastric lymph node (13 patients). However, metastasis was not observed in the regional and distant lymph node in 10 patients, whereas 36 patients were not evaluated. Furthermore, of the 13 patients who developed celiac axis and gastric lymph node metastases, 3 were in stage T1N0-1M0 and 10 were in stage T2-4N0-1M0. A complete response appeared in 12 patients, whereas a partial response appeared in 1 patient. The mean survival time of the

    Full Text Available Abstract Background Sentinel lymph node biopsy (SLNB is now considered a standard of care in early breast cancers with N0 axillae; however, its role in locally advanced breast cancer (LABC after neo-adjuvant chemotherapy (NACT is still being debated. The present study assessed the feasibility, efficacy and accuracy of sentinel lymph node biopsy (SLNB using "dye alone" (methylene blue method in patients with LABC following NACT. Materials and methods Thirty, biopsy proven cases of LABC that had received three cycles of neo-adjuvant chemotherapy (cyclophosphamide, adriamycin, 5-fluorouracil were subjected to SLNB (using methylene blue dye followed by complete axillary lymph node dissection (levels I-III. The sentinel node(s was/were and the axilla were individually assessed histologically. The SLN accuracy parameters were calculated employing standard definitions. The SLN identification rate in the present study was 100%. The sensitivity of SLNB was 86.6% while the accuracy was 93.3%, which were comparable with other studies done using dual lymphatic mapping method. The SLN was found at level I in all cases and no untoward reaction to methylene blue dye was observed. Conclusions This study confirms that SLNB using methylene blue dye as a sole mapping agent is reasonably safe and almost as accurate as dual agent mapping method. It is likely that in the near future, SLNB may become the standard of care and provide a less morbid alternative to routine axillary lymph node dissection even in patients with LABC that have received NACT.

    In early breast cancer axillary nodes are usually impalpable and over 50% of such patients may have an axillary clearance when no nodes are involved. This work identifies axillary node status by imaging with a Tc-99m radiolabelled anti-Polymorphic Epithelial Mucin, humanised monoclonal antibody (human milk fat globule 1), prior to surgery in 30 patients. Change detection analysis of image data with probability mapping is undertaken. A specificity of 93% and positive predictive value of 92% (both 100% if a second cancer in the axilla with negative nodes is considered) were found. A strategy for combining negative imaging with the sentinel node procedure is presented. Copyright 2002 Cancer Research UK

    Few imaging methods are available for depicting in vivo cancer cell migration within the lymphatic system. Detection of such early micrometastases requires extremely high target to background. In this study, we dual-labeled human breast cancer cells (MDA-MB468) with a small particle of iron oxide (SPIO) and a quantum dot (QD), and tracked these cells in the lymphatic system in mice using in vivo MRI and optical imaging. A generation-6 gadolinium-dendrimer-based MRI contrast agent (Gd-G6) was employed for visualizing regional lymphatic channels and nodes. Since Gd-G6 shortened T(1) leading to high signal, whereas SPIO-labeled cancer cells greatly lowered signal, a small number of cells were simultaneously visualized within the draining lymphatic basins. One million dual-labeled cancer cells were subcutaneously injected into the paws of mice 24 h prior to imaging. Then whole body images were acquired pre- and post-intracutaneous injection of Gd-G6 with 3D-T(1) w-FFE and balanced-FFE sequences for cancer cell tracking and MR lymphangiography. In vivo MRI clearly visualized labeled cancer cells migrating from the paw to the axillary lymph nodes using draining lymphatics. In vivo optical imaging using a fluorescence surgical microscope demonstrated tiny cancer cell clusters in the axillary lymph node with high spatial resolution. Thus, using a combination of MRI and optical imaging, it is possible to depict macro- and early micrometastases within the lymphatic system. This platform offers a versatile research tool for investigating and treating lymphatic metastases in animal models. Copyright © 2011 John Wiley & Sons, Ltd.

    A controversial aspect of breast cancer management is the use of sentinel lymph node biopsy (SLNB) in patients requiring neoadjuvant chemotherapy (NCT). This paper discusses the detection rate (DT) and false negatives (FN) of SLNB after NCT to investigate the influence of initial nodal disease and the protocols applied. Prospective observational multicenter study in women with breast cancer, treated with NCT and SLNB post-NCT with subsequent lymphadenectomy. DT and FN rates were calculated, both overall and depending on the initial nodal status or the use of diagnostic protocols pre-SLNB. No differences in DT between initial node-negative cases and positive cases were found (89.8 vs. 84.4%, P=.437). Significant differences were found (94.1 vs. 56.5%, P=0,002) in the negative predictive value, which was lower when there was initial lymph node positivity, and a higher rate of FN, not significant (18.2 vs. 43.5%, P=.252) in the same cases. The axillary study before SLNB and after the NCT, significantly decreased the rate of FN in patients with initial involvement (55.6 vs 12.5, P=0,009). NCT means less DT and a higher rate of FN in subsequent SLNB, especially if there is initial nodal involvement. The use of protocols in axillary evaluation after administering the NCT and before BSGC, decreases the FN rate in these patients. Copyright © 2013 AEC. Publicado por Elsevier España, S.L.U.

    Large field of view gamma cameras are widely used to perform lymphoscintigraphy in the sentinel lymph nodes (SLN) procedure in case of breast cancer. However, they are not specified for this application and their sizes do not enable their use in the operative room to control the excision of the all SLN. We present the results obtained with a prototype of a new mini gamma camera developed especially for the operative lymphoscintigraphy of the axillary area in case of breast cancer. This prototype is composed of 10 mm thick parallel lead collimator, a 2 mm thick GSO:Ce inorganic scintillating crystal from Hitachi and a Hamamatsu H8500 flat panel multianode (64 channels) photomultiplier tube (MAPMT) equipped with a dedicated electronics. Its actual field of view is 50 × 50mm2. The gamma interaction position in the GSO scintillating plate is obtained by calculating the center of gravity of the fired MAPMT channels. The measurements performed with this prototype demonstrate the usefulness of this mini gamma camer...

    The sentinel lymph node (SNL) detection in breast cancer has been recently validated. It allows the reduction of the number of axillary dissections and their corresponding side effects. We tested a simple method of image truncation in order to improve the sensitivity of lymphoscintigraphy. This approach is justified by the magnitude of uptake difference between the injection site and the SNL. We prospectively investigated SNL detection using a triple method (lymphoscintigraphy, blue dye and surgical radio detection) in 130 patients. SNL was identified in 104 of the 132 patients (80%) using the standard images and in 126 of them (96, 9%) using the truncated images. Blue dye detection and surgical radio detection had a sensitivity of 76,9% and 98,5% respectively. The false negative rate was 10,3%. 288 SNL were dissected, 31 were metastatic. Among the 19 patients with metastatic SNL and more than one SNL detected, the metastatic SNL was not the hottest in 9 of them. 28 metastatic SNL were detected Y on truncated images versus only 19 on standard images. Truncation which dramatically increases the sensitivity of lymphoscintigraphy allows to increase the number of dissected SNL and probably reduces the false negative rate. (author)

    Sentinel lymph node biopsy (SLNB) has been unevenly adopted into practice in Canada. In this qualitative study, the authors explored individual, institutional, and policy factors that may have influenced SLNB adoption. This information will guide interventions to improve SLNB implementation. Qualitative methodology was used to examine factors influencing SLNB adoption. Grounded theory guided data collection and analysis. Semistructured interviews were based on Roger's diffusion of innovation theory. Purposive and snowball sampling was used to identify participants. Semistructured telephone interviews were conducted with urban, rural, academic, and community health care providers and administrators to ensure all perspectives and motivations were explored. Two individuals independently analyzed data and achieved consensus on emerging themes and their relationship. A total of 43 interviews were completed with 21 surgeons, 5 pathologists, 7 nuclear medicine physicians, and 10 administrators. Generated themes included awareness of SLNB with the exception of some administrators, acknowledged advantage of SLNB, SLNB compatibility with beliefs regarding axillary staging, acknowledgment that SLNB was a complex innovation to adopt, extensive trialing of SLNB prior to adoption, observable benefits with SLNB, acknowledgment that hospital-level administrative support enabled adoption, desire for a provincial policy supporting SLNB to assist in hospital-level adoption, requirement of a local high-volume breast surgery champion who communicated extensively with team to facilitate local adoption, and need for credentialing of SLNB to ensure quality. SLNB is a complex innovation to adopt. Successful adoption was assisted by a high-volume breast cancer surgical champion, interprofessional communication, and administrative support.

    Lymph nodes tuberculosis represents 30 percent of extra pulmonary tuberculosis in Morocco. We report here the experience of the pulmonology unit of the Avicenne Military Hospital in Marrakech for a period of 4 years. Our study interested 30 patients (15 males and 15 females) with an average age of 29 years old (10 to 62 years old). Tuberculosis has interested a single site in 28 patients, the other two patients had multiple but unilateral involvement. For the single sites, locations were jugulo-carotidian (20 patients), supra-calvicular (2 patients), axillary (2 patients), sub-mandibular (2 patients), spinal (2 patients) and mediastinal (2 patients). For the multiple locations, the involvement was jugulo-carotidian, sub-mandibular, spinal and sub-clavicular for one patient; and jugulo-carotidian and sub-clavicular for the other. Diagnosis was made by surgical biopsy and histology for all the patients. A six-month anti-tuberculous treatment was given afterward, with relapses in two patients.

    Full Text Available The aim of this study was to assess the efficacy (response rate centered on 80% of a somatostatin analog with high affinity for 4 somatostatin receptors in reducing the postoperative incidence of symptomatic lymphocele formation following total mastectomy with axillary lymph node dissection.This prospective, double-blind, randomised, placebo-controlled, phase 2 trial was conducted in two secondary care centres.All female patients for whom mastectomy and axillary lymph node dissection were indicated were eligible for the study, including patients who had received neo-adjuvant chemotherapy. Main exclusion criteria were related to diabetes, cardiac insufficiency, disorder of cardiac conduction or hepatic failure.Patients were randomised to receive one injection of either prolonged-release pasireotide 60 mg or placebo (physiological serum, which were administered intramuscularly 7 to 10 days before the scheduled surgery. The study was conducted in a double-blind manner.The primary outcome measure was the percentage of patients who did not develop post-operative axillary symptomatic lymphoceles during the 2 postoperative months. Secondary endpoints were the total quantity of lymph drained, duration and daily volume of drainage and aspirated volumes of lymph.Ninety-one patients were randomised. Ninety patients were evaluable: 42 patients received pasireotide, and 48 patients received placebo. The mean estimated response rate were 62.4% (95% Credibility Interval [CrI]: 48.6%-75.3% in the treatment group and 50.2% (95% CrI: 37.6%-62.8% in the placebo group. Overall safety was comparable across groups, and one serious adverse event occurred. In the treatment group, one patient with known insulin-depe*ndent diabetes required hospitalization for hyperglycaemia.With this phase 2 preliminary study, even if our results indicate a trend towards a reduction in symptomatic lymphocele, pre-operative injection of pasireotide failed to achieve a response rate

It is highly desirable to have a method of identifying those patients who would benefit from further treatment of the neck when they are clinically node-negative. The purpose of the present study was to examine the use of sentinel lymph node biopsy in identifying occult neck disease in a cohort of patients with node-negative oral cavity and oropharyngeal squamous cell carcinoma. DESIGN: We evaluated a total of 13 patients with oral cavity and oropharyngeal cancer who were clinically and radiologically node-negative. RESULTS: A sentinel lymph node was found in all 13 patients, revealing metastatic disease in five patients, four of whom had one or more positive sentinel lymph nodes. There was one false negative result, in which the sentinel lymph node was negative for tumour whereas histological examination of the neck dissection specimen showed occult disease. CONCLUSION: In view of these findings, we would recommend the use of sentinel lymph node biopsy in cases of oral cavity and oropharyngeal squamous cell carcinoma, in order to aid the differentiation of those patients whose necks are harbouring occult disease and who require further treatment.

    To assess the influence of time on the reliability of sentinel lymph node biopsy (SLNB) in breast cancer patients with previous excisional biopsy (EB), analyzing both the sentinel lymph node detection and the lymph node recurrence rate. Thirty-six patients with cT1/T2 N0 breast cancer and previous EB of the lesion underwent a lymphoscintigraphy after subdermal periareolar administration of radiocolloid, the day before SLNB. Patients were classified into two groups, one including 12 patients with up to 29 days elapsed between EB and SLNB (group A), and another with the remaining 24 in which time between both procedures was of 30 days or more (group B). Scintigraphic and surgical detection of the sentinel lymph node, histological status of the sentinel lymph node and of the axillary lymph node dissection, if performed, and lymphatic recurrences during follow-up, were analyzed. Sentinel lymph node visualization at the lymphoscintigraphy and surgical detection were 100% in both groups. Histologically, three patients showed macrometastasis in the sentinel lymph node, one from group A and two from group B. None of the patients, not even those with malignancy of the sentinel lymph node, relapsed after a medium follow-up of 49.5 months (24-75). Time elapsed between EB and SLNB does not influence the reliability of this latter technique as long as a superficial injection of the radiopharmaceutical is performed, proving a very high detection rate of the sentinel lymph node without evidence of lymphatic relapse during follow-up.

    The emergence of sentinel lymph node (SLN) technology has provided the ability for an in depth pathologic evaluation for the detection of metastasis to lymph nodes through the use of ultra-staging. The SLN has been shown to be predictive of the metastatic status of its nodal basin. More recently, SLN dissections have been employed in the evaluation of the inguinal lymphatic basins in patients with vulvar malignancies. We hypothesize that the average size of metastasis detected in non-palpable inguinal lymph nodes is smaller when detected through the use of SLN dissection and ultra-staging versus complete inguinal node dissection (CND). This was an IRB approved retrospective study. The tumor registry database was searched to identify all patients diagnosed with a vulvar malignancy from 1990 to 2004. The records were reviewed to identify patients with inguinal lymph node metastasis. Only patients with non-palpable inguinal lymph nodes (metastasis 1 cm or less) were included in the analysis. All pathology slides were reviewed. The smallest metastatic foci of cells were measured from lymph nodes obtained through the traditional complete inguinal lymph node dissection (CND) and compared with the largest metastatic foci of cells detected in sentinel lymph node dissections. The mean size and standard deviation for each group was calculated and analyzed with a Mann-Whitney test. There were 336 inguinal node dissections performed in patients identified with a vulvar malignancy. SLN dissections were performed in 52 groins and CND in 284 groins. Fifty-eight patients were found to have metastatic disease to the inguinal lymph nodes. Thirty of these patients had no evidence of lymph node metastasis on clinical exam or at the time of their EUA. There were 7 groins with metastasis detected through an SLN and 23 groins through a CND. The mean size of the metastatic foci detected in the SLN group was 2.52 mm (SD 1.55) and in the CND group was 4.35 mm (SD 2.63). This was not

    Since the introduction of the sentinel node technique for breast cancer in the 1990s patient's morbidity was reduced. Tracer uptake is known to be dependent from lymph node integrity and activity of macrophages. The aim of this study was to assess whether radioactivity of the tracer can predict sentinel lymph node metastases. Furthermore, a potential association with Ki-67 index was examined. Non-invasive prediction of lymph node metastases could lead to a further decrease of morbidity. We retrospectively analyzed patients with primary breast cancer who underwent surgery at the Department of Obstetrics and Gynecology in the University Hospital of Cologne between 2012 and 2013. Injection of radioactive tracer was done a day before surgery in the department of Nuclear Medicine. Clinical data and radioactivity of the sentinel node measured the day before and intraoperatively were abstracted from patient's files. Of 246 patients, 64 patients had at least one, five patients had two and one patient had three positive sentinel lymph nodes. Occurrence of sentinel lymph node metastases was not associated with preoperative tracer activity (p = 0,319), intraoperative tracer activity of first sentinel node (p = 0,086) or with loss of tracer activity until operation (p = 0,909). There was no correlation between preoperative Ki-67 index and occurrence of lymph node metastases (p = 0,403). In our cohort, there was no correlation between radioactivity and sentinel node metastases. Tracer uptake might not only be influenced by lymph node metastases and does not predict metastatic lymph node involvement. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Introduction: Particle size of colloids employed for sentinel lymph node (LN) detection is not well studied. This investigation aimed to correlate particle size and distribution of different products with LN uptake. Methods: All agents (colloidal tin, dextran, phytate and colloidal rhenium sulfide) were labeled with {sup 99m}Tc according to manufacturer's instructions. Sizing of particles was carried out on electron micrographs using Image Tool for Windows (Version 2.0). Biodistribution studies in main excretion organs as well as in popliteal LN were performed in male Wistar rats [30 and 90 min post injection (p.i.)]. The injected dose was 0.1 ml (37 MBq) in the footpad of the left posterior limb. Dynamic images (0-15 min p.i.) as well as static ones (30 and 90 min) were acquired in gamma camera. Results: Popliteal LN was clearly reached by all products. Nevertheless, particle size remarkably influenced node uptake. Colloidal rhenium sulfide, with the smallest diameter (5.1x10{sup -3}{+-}3.9x10{sup -3} {mu}m), permitted the best result [2.72{+-}0.64 percent injected dose (%ID) at 90 min]. Phytate displayed small particles (<15 {mu}m) with favorable uptake (1.02{+-}0.14%ID). Dextran (21.4{+-}12.8 {mu}m) and colloidal tin (39.0{+-}8.3 {mu}m) were less effective (0.55{+-}0.14 and 0.06{+-}0.03%ID respectively). Particle distribution also tended to influence results. When asymmetric, it was associated with biphasic uptake which increased over time; conversely, symmetric distribution (colloidal tin) was consistent with a constant pattern. Conclusion: The results are suggesting that particle size and symmetry may interfere with LN radiopharmaceutical uptake.

    Block dissection of the inguinal lymph nodes is the routine management for palpable metastatic melanoma confined to this node basin. Involvement of the next tier external iliac and obturator lymph nodes in the pelvis is common, and untreated pelvic nodal disease can become advanced before becoming clinically apparent. We have routinely performed combined inguinal and pelvic (ilioinguinal) lymph node block dissection to avoid this morbid outcome. A retrospective analysis of all patients undergoing ilioinguinal lymph node dissection for melanoma between January 1998 and January 2006 was carried out. There were 72 patients with a median age of 52.7 years (19.7-75.2 years) who were followed up for a median of 28.9 months (1.0-115.0 months) after ilioinguinal lymph node dissection. There were 22 (30.6%) of 72 patients with histologically involved pelvic lymph nodes. Preoperative computed tomography (CT) scanning accuracy for pelvic lymph node involvement was as follows: sensitivity 60.0%, specificity 100.0%, positive predictive value 100.0% and negative predictive value 86.2%. Lymphoedema was reported in 32 (44.4%) of 72 patients. Median time to first recurrence was 8.7 months (0.8-69.7 months). Regional recurrence occurred in 6 (8.3%) of 72 patients at a median of 4.9 months (0.9-32.0 months). Extranodal spread was the only factor adversely associated with disease-free survival. In all patients, 5-year disease-free survival was 38% (95% confidence interval (CI) 26-50) and overall survival 47% (95% CI 33-60). Palpable metastatic melanoma in the groin is commonly associated with pelvic lymph node involvement, is not well predicted by CT scanning and is appropriately managed by ilioinguinal lymph node block dissection.

    Objective: To study the characteristics of spiral computed tomography (SCT) in the diagnosis of lymph nodes metastases in gastric cancer. Methods: The characteristics of spiral computed tomography (SCT) of metastatic lymph nodes in 35 gastric cancer patients were analyzed and compared with operation and pathology. Results: A total amount of 379 lymph nodes (positive 173, negative 206) were detected by SCT and confirmed by pathology in metastasis-positive or metastasis-negative patients. The positive rate with diameter of lymph nodes ≥ 10 mm is 62.7%. The positive rate with ir- regular shape and uneven enhancement lymph nodes were 96.3% and 89.4%. If the attenuation values, more than or equal to 25 HU in plain scan or 70 HU in arterial phase or 80 HU in venous phase, were used as the threshold to detect the metastasis-positive lymph nodes, the positive rate were 55.7%, 56.3%, 67.8% respectively. Conclusion: SCT is valuable in judging the metastasis in gastric cancer. The reference of diameter ≥ 10mm, combining with the shape and the attenuation values can dramatically improve the diagnosis of lymph node metastasis in gastric cancer. (authors)

    Full Text Available OBJECTIVE: Lymph node yield is recommended as a benchmark of quality care in colorectal cancer. The objective of this study was to evaluate the impact of various factors upon lymph node yield and to identify independent factors associated with lymph node harvest. MATERIALS AND METHODS: The records of 162 patients with Stage I to Stage III colorectal cancers seen in one institution were reviewed. These patients underwent radical surgery as definitive therapy; high-risk patients then received adjuvant treatment. Pathologic and demographic data were recorded and analyzed. The subgroup analysis of lymph node yields was determined using a t-test and analysis of variants. Linear regression model and multivariable analysis were used to perform potential confounding and predicting variables. RESULTS: Five variables had significant association with lymph node yield after adjustment for other factors in a multiple linear regression model. These variables were: tumor size, surgical method, specimen length, and individual surgeon and pathologist. The model with these five significant variables interpreted 44.4% of the variation. CONCLUSIONS: Patients, tumor characteristics and surgical variables all influence the number of lymph nodes retrieved. Physicians are the main gatekeepers. Adequate training and optimized guidelines could greatly improve the quality of lymph node yields.

    Despite the knowledge of alternate lymphatic draining patterns of the breast, routine evaluation of the internal mammary lymph node basin is still not considered standard of care. The advent of microsurgical breast reconstruction using the internal mammary vessels as recipients, however, has allowed sampling of internal mammary lymph nodes with technical ease, thus revisiting their role in breast cancer management. In the present study, the authors reviewed their experience with this practice. A retrospective analysis of patients who underwent internal mammary lymph node biopsy at the time of autologous breast reconstruction using the internal mammary vessels between 2004 and 2012 was performed. Parameters of interest included patient age, timing of reconstruction (immediate versus delayed), disease stage, and pathologic findings of internal mammary lymph nodes. A total of 264 autologous breast reconstructions using the internal mammary vessels were performed in 204 patients with a median age of 44.5 years. The majority of reconstructions were immediate [n = 211 (79.9 percent)]. Seventy-two percent of patients had either stage I [72 patients (35.3 percent)] or stage II disease [75 patients (36.8 percent)]. Six patients were found to have internal mammary lymph node metastasis. Stage migration and alteration in adjuvant therapy occurred in all patients. Internal mammary lymph node sampling at the time of autologous breast reconstruction using the internal mammary system should become routine practice, as the morbidity associated with internal mammary lymph node harvest is low and the impact in cases of nodal involvement is quite substantial.

    To analyze predictive factors for lymph node metastasis in early gastric cancer. We analyzed 1104 patients with early gastric cancer (EGC) who underwent a gastrectomy with lymph-node dissection from May 2003 through July 2011. The clinicopathologic factors and molecular markers were assessed as predictors for lymph node metastasis. Molecular markers such as microsatellite instability, human mutL homolog 1, p53, epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) were included. The χ(2) test and logistic regression analysis were used to determine clinicopathologic parameters. Lymph node metastasis was observed in 104 (9.4%) of 1104 patients. Among 104 cases of lymph node positive patients, 24 patients (3.8%) were mucosal cancers and 80 patients (16.7%) were submucosal. According to histologic evaluation, the number of lymph node metastasis found was 4 (1.7%) for well differentiated tubular adenocarcinoma, 45 (11.3%) for moderately differentiated tubular adenocarcinoma, 36 (14.8%) for poorly differentiated tubular adenocarcinoma, and 19 (8.4%) for signet ring cell carcinoma. Of 690 EGC cases, 77 cases (11.2%) showed EGFR overexpression. HER2 overexpression was present in 110 cases (27.1%) of 406 EGC patients. With multivariate analysis, female gender (OR = 2.281, P = 0.009), presence of lymphovascular invasion (OR = 10.950, P tumor size, lymphovascular invasion and EGFR overexpression were predictive risk factors for lymph node metastasis in EGC.

  17. A cut-off of 2150 cytokeratin 19 mRNA copy number in sentinel lymph node may be a powerful predictor of non-sentinel lymph node status in breast cancer patients.

    Full Text Available Since 2007, one-step nucleic acid amplification (OSNA has been used as a diagnostic system for sentinel lymph node (SLN examination in patients with breast cancer. This study aimed to define a new clinical cut-off of CK19 mRNA copy number based on the calculation of the risk that an axillary lymph node dissection (ALND will be positive. We analyzed 1529 SLNs from 1140 patients with the OSNA assay and 318 patients with positive SLNs for micrometastasis (250 copies and macrometastasis (5000 copies underwent ALND. Axillary non-SLNs were routinely examined. ROC curves and Youden's index were performed in order to identify a new cut-off value. Logistic regression models were performed in order to compare OSNA categorical variables created on the basis of our and traditional cut-off to better identify patients who really need an axillary dissection. 69% and 31% of OSNA positive patients had a negative and positive ALND, respectively. ROC analysis identified a cut-off of 2150 CK19 mRNA copies with 95% sensitivity and 51% specificity. Positive and negative predictive values of this new cut-off were 47% and 96%, respectively. Logistic regression models indicated that the cut-off of 2150 copies better discriminates patients with node negative or positive in comparison with the conventional OSNA cut-off (p<0.0001. This cut-off identifies false positive and false negative cases and true-positive and true negative cases very efficiently, and therefore better identifies which patients really need an ALND and which patients can avoid one. This is why we suggest that the negative cut-off should be raised from 250 to 2150. Furthermore, we propose that for patients with a copy number that ranges between 2150 and 5000, there should be a multidisciplinary discussion concerning the clinical and bio-morphological features of primary breast cancer before any decision is taken on whether to perform an ALND or not.

    Reactive cervical lymphadenopathy is common in children and may demonstrate increased 18 F-fluoro-deoxyglucose ( 18 F-FDG) uptake on positron emission tomography/computed tomography (PET/CT). We sought to evaluate the frequency and significance of 18 F-FDG uptake by neck lymph nodes in children with no history of head and neck cancer. The charts of 244 patients (114 female, mean age: 10.4 years) with a variety of tumors such as lymphoma and post-transplant lymphoproliferative diseases (PTLD), but no head and neck cancers, who had undergone 18 F-FDG PET/CT were reviewed retrospectively. Using the maximum standardized uptake value (SUVmax), increased 18 F-FDG uptake by neck lymph nodes was recorded and compared with the final diagnosis based on follow-up studies or biopsy results. Neck lymph node uptake was identified in 70/244 (28.6%) of the patients. In 38 patients, the lymph nodes were benign. In eight patients, the lymph nodes were malignant (seven PTLD and one lymphoma). In 24 patients, we were not able to confirm the final diagnosis. Seven out of the eight malignant lymph nodes were positive for PTLD. The mean SUVmax was significantly higher in malignant lesions (4.2) compared with benign lesions (2.1) (P = 0.00049). 18 F-FDG uptake in neck lymph nodes is common in children and is frequently due to reactive lymph nodes, especially when the SUVmax is cervical lymph nodes is higher in PTLD patients compared with other groups.

    Lona Jalini

    2016-01-01

    Full Text Available Background: Axillary lymph node status is the most important breast cancer prognostic factor. Preoperative axillary ultrasound examination (PAUS is used to triage patients for sentinel lymph node biopsy (SLNB or axillary lymph node dissection (ALND. We assessed the detection rate of lymph node metastases by PAUS in a screening unit and evaluated associations between clinicopathological factors and PAUS positivity. Patients and Methods: This was a single-centre retrospective analysis of data extracted from a hospital breast cancer database and clinical records. Clinical, radiological, and pathological and prognostic indices were compared between PAUS-positive and PAUS-negative patients subsequently found to have lymph node metastases on histopathological analysis. Results: Two hundred and two patients were eligible for analysis. 50.5% of lymph node-positive patients were correctly identified as PAUS positive. Patients with PAUS-positive lymph nodes had less favorable disease characteristics, namely clinically palpable lymph nodes, higher Nottingham prognostic (NPI index, high lymph node burden according to the European Society of Medical Oncology (ESMO group classification, and larger, grade 3 tumors with lymphovascular invasion and extranodal spread. Moreover, PAUS-positive patients had more macrometastases and lymph node involvement than PAUS-negative patients. Conclusion: PAUS-positive patients and PAUS-negative (SLNB-positive patients have different clinicopathological characteristics. The presence of LVI, extranodal spread, grade 3 histology, or large tumors with poor prognostic indices in PAUS-negative patients should be regarded with caution and perhaps prompt second-look ultrasound examination.

    To evaluate the ability of the log odds of positive lymph nodes to predict prognosis in patients with non-small cell lung cancer (NSCLC). Correlations between the log odds of positive lymph nodes, numbers of dissected lymph nodes, dissected lymph node stations, positive lymph nodes, positive lymph node ratio, and positive lymph node stations were retrospectively evaluated using Pearson correlation coefficients (r), survival analysis by Kaplan-Meier, Cox hazard ratio model, and log-rank tests. The numbers of dissected lymph nodes, positive lymph nodes, dissected lymph node stations and positive lymph node stations significantly correlated with the log odds of positive lymph nodes (P log odds of positive lymph nodes -1.412 were 63.9% and 32.5%, respectively (P log odds of positive lymph nodes are independent risk factors for overall survival (hazard ratio = 2.660, 95% confidence interval 2.114-3.346, P log odds of positive lymph nodes and a tumor node metastasis (TNM) staging system was established for predicting survival. The log odds of positive lymph nodes are superior to the positive lymph node ratio and p-N-stage for predicting prognosis of NSCLC. A new staging system that combines log odds of positive lymph nodes and the current TNM staging system predicts prognosis more accurately than the TNM system alone.

    Full Text Available Cystosarcoma phyllodes are uncommon breast tumors which rarely metastasize to axillary lymph nodes. The tumor is similar to fibroadenoma in structure, but it is different histologically. Although surgery (excision vs. mastectomy is the mainstay of treatment, the need for adjuvant therapies such as radiotherapy for a malignant variety is unclear. Its association with ipsilateral tubercular axillary lymph nodes has not been reported in literature so far. We report a 35-year-old female that presented with a giant borderline malignant phyllodes tumor of the right breast along with ipsilateral tubercular granulomatous axillary lymph nodes.

    Rhabdomyosarcoma (RMS) is an aggressive and fast-growing malignant tumor. RMS predominantly arises in the head and neck of infancy and children. Metastasis is usually via the blood vessel. We report a case of a recurred RMS of the tongue base w
