    Full Text Available Given the critical role of CYP19 in estrogen synthesis, we investigated the influence of CYP19 gene polymorphisms on the clinical outcome of lymph node- (LN- negative, hormone receptor- (HR- positive early breast cancers. Genotyping for the CYP19 polymorphisms rs4646 (A/C, rs1065779 (A/C, CYP19 (TTTAn (short allele/long (S/L allele using the 7 TTTA repeat polymorphism as the cut-off, and rs1870050 (A/C was performed on 296 patients with LN-negative, HR-positive breast cancers. All patients received adjuvant hormonal therapy. Associations were examined between these 4 genotypes and 6 common haplotypes of CYP19 and distant disease-free survival (DDFS, disease-free survival (DFS, and overall survival (OS. Patients were divided into the 6 subhaplotypes of CCLA (41.1%, AASA (17.1%, CASA (11.9%, CCLC (8.9%, CCSA (7.5%, AASC (8.9%, and others (4.6%. In premenopausal patients, haplotype AASA was significantly associated with a poor DDFS (adjusted hazard ratio (aHR, 3.3; P=0.001, DFS (aHR, 2.5; P=0.0008, and OS (aHR, 2.9; P=0.0004 after adjusting for age, tumor size, tumor grade, estrogen receptor status, progesterone receptor status, chemotherapy, pathology, adjuvant hormone therapy, menopausal status, and radiotherapy. Furthermore, haplotype AASA remained a negative prognostic factor for premenopausal patients receiving adjuvant chemotherapy in terms of DDFS (aHR, 4.5; P=0.0005, DFS (HR, 3.2; P=0.003, and OS (HR, 6.4; P=0.0009. However, in postmenopausal patients, haplotype AASA was not associated with a poor prognosis, whereas the AASC haplotype was significantly associated with a poor DFS (aHR, 3.1; P=0.03 and OS (aHR, 4.4; P=0.01. Our results indicate that, in patients with LN-negative, HR-positive breast cancers, genetic polymorphism haplotype AASA is associated with poor survival of premenopausal women but does not affect survival of postmenopausal women.

    Artificial neural networks (ANNs) can be used to develop a technique to classify lymph node negative breast cancer that is prone to distant metastases based on gene expression signatures. The neural network used is a multilayered feed forward network that employs back propagation algorithm. Once trained with DNA microarraybased gene expression profiles of genes that were predictive of distant metastasis recurrence of lymph node negative breast cancer, the ANNs became capable of correctly classifying all samples and recognizing the genes most appropriate to the classification. To test the ability of the trained ANN models in recognizing lymph node negative breast cancer, we analyzed additional idle samples that were not used beforehand for the training procedure and obtained the correctly classified result in the validation set. For more substantial result, bootstrapping of training and testing dataset was performed as external validation. This study illustrates the potential application of ANN for breast tumor diagnosis and the identification of candidate targets in patients for therapy.

    AIM: To investigate the long-term effect of the number of resected lymph nodes (LNs) on the prognosis of patients with node-negative gastric cancer. METHODS: Clinical data of 211 patients with gastric cancer, without nodal involvement, were analyzed retrospectively after D2 radical operation. We analyzed the relationship between the number of resected LNs with the 5-year survival, the recurrence rate and the post-operative complication rate.RESULTS: The 5-year survival of the entire cohort was 82.2%. The total number of dissected LNs was one of the independent prognostic factors. Among patients with comparable depth of invasion, the larger the number of resected LNs, the better the survival ( P 0.05).CONCLUSION: For node-negative gastric cancer,sufficient number of dissected LNs is recommended during D2 lymphadenectomy, to improve the long-term survival and reduce the recurrence. Suitable increments of the dissected LN count would not increase the postoperative complication rate.

    Full Text Available Abstract Background It is of great significance to find better markers to correctly distinguish between high-risk and low-risk breast cancer patients since the majority of breast cancer cases are at present being overtreated. Methods 46 tumours from node-negative breast cancer patients were studied with gene expression microarrays. A t-test was carried out in order to find a set of genes where the expression might predict clinical outcome. Two classifiers were used for evaluation of the gene lists, a correlation-based classifier and a Voting Features Interval (VFI classifier. We then evaluated the predictive accuracy of this expression signature on tumour sets from two similar studies on lymph-node negative patients. They had both developed gene expression signatures superior to current methods in classifying node-negative breast tumours. These two signatures were also tested on our material. Results A list of 51 genes whose expression profiles could predict clinical outcome with high accuracy in our material (96% or 89% accuracy in cross-validation, depending on type of classifier was developed. When tested on two independent data sets, the expression signature based on the 51 identified genes had good predictive qualities in one of the data sets (74% accuracy, whereas their predictive value on the other data set were poor, presumably due to the fact that only 23 of the 51 genes were found in that material. We also found that previously developed expression signatures could predict clinical outcome well to moderately well in our material (72% and 61%, respectively. Conclusion The list of 51 genes derived in this study might have potential for clinical utility as a prognostic gene set, and may include candidate genes of potential relevance for clinical outcome in breast cancer. According to the predictions by this expression signature, 30 of the 46 patients may have benefited from different adjuvant treatment than they recieved. Trial

    Full Text Available Objective. The study was designed to explore the prognostic value of examined lymph node (LN number on survival of gastric cancer patients without LN metastasis. Methods. Between August 1995 and January 2011, 300 patients who underwent gastrectomy with D2 lymphadenectomy for LN-negative gastric cancer were reviewed. Patients were assigned to various groups according to LN dissection number or tumor invasion depth. Some clinical outcomes, such as overall survival, operation time, length of stay, and postoperative complications, were compared among all groups. Results. The overall survival time of LN-negative GC patients was 50.2±30.5 months. Multivariate analysis indicated that LN dissection number (P30. Besides, it was not correlated with operation time, transfusion volume, length of postoperative stay, or postoperative complication incidence (P>0.05. Conclusions. The number of examined lymph nodes is an independent prognostic factor of survival for patients with lymph node-negative gastric cancer. Sufficient dissection of lymph nodes is recommended during surgery for such population.

    The aim of this study was to evaluate p53 expression, determined by immunohistochemistry, in 151 infiltrating ductal breast carcinomas with negative axillary lymph nodes, and to determine whether p53 can be considered as an independent prognostic value for overall and disease-free survival. A monoclonal antibody (DO-7) that reacts with an epitope on the N terminal portion of the human protein p53 was used to detect p53 in paraffin-embedded sections, utilising a standard avidin-biotin-peroxidase complex (ABC) technique with a microwave oven antigen retrieval. Overexpression of p53 (more than 50% of stained cells) was found in 45 cases (30%). Forty-five cases were negative and occasionally or moderately stained cells were present in 61 cases. p53 protein overexpression was significantly associated with high histological grade and tumour necrosis, high MIB-1 value (MIB-1 > 30%) and negative oestrogen receptor status. Univariate analysis (log-rank) showed a shorter overall survival (P = 0.003) in patients with high tumour p53 positivity. This statistical significance was also seen on multivariate analysis (Cox's logistic regression, P = 0.004). p53 protein overexpression is an independent prognostic marker in node-negative breast carcinoma for overall survival and should be used with other prognostic factors.

    Recently, there has been controversy about the relationship between the number of lymph nodes removed and survival of patients diagnosed with lymph node-negative breast cancer. To assess this relationship, 603 cases of lymph node-negative breast cancer with a median of 126 months of follow-up data were studied. Patients were stratified into two groups (Group A, 10 or fewer tumor-free lymph nodes removed; Group B, more than 10 tumor-free lymph nodes removed). The number of tumor-free lymph nodes in ipsilateral axilary resections as wel as 5 other disease parameters were analyzed for prognostic value. Our results revealed that the risk of death from breast cancer was significantly associated with patient age, marital status, histologic grade, tumor size, and adjuvant therapy. The 5- and 10-year survival rates for patients with 10 or fewer tumor-free lymph nodes removed was 88.0% and 66.4%, respectively, compared with 69.2% and 51.1%, respectively, for patients with more than 10 tumor-free lymph nodes removed. For patients with 10 or fewer tumor-free lymph nodes removed, the adjusted hazard ratio (HR) for risk of death from breast cancer was 0.579 (95% confidence interval, 0.492-0.687,P < 0.001), independent of patient age, marital status, histologic grade, tumor size, and adjuvant therapy. Our study suggests that the number of tumor-free lymph nodes removed is an independent predictor in cases of lymph node-negative breast cancer.

    OBJECTIVES: Considerable controversy exists regarding the merits of elective neck dissection in patients with early stage oral cavity and oropharyngeal squamous cell carcinoma. 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.

    The presence of lymph nodes metastasis is one of the most important prognostic indicators in gastric cancer. The micrometastases have been studied as prognostic factor in gastric cancer, which are related to decrease overall survival and increased risk of recurrence. However, their identification is limited by conventional methodology, since they can be overlooked after routine staining. To investigate the presence of occult tumor cells using cytokeratin (CK) AE1/AE3 immunostaining in gastric cancer patients histologically lymph node negative (pN0) by H&E. Forty patients (T1-T4N0) submitted to a potentially curative gastrectomy with D2 lymphadenectomy were evaluated. The results for metastases, micrometastases and isolated tumor cells were also associated to clinicopathological characteristics and their impact on stage grouping. Tumor deposits within lymph nodes were defined according to the tumor-node-metastases guidelines (7th TNM). A total of 1439 lymph nodes were obtained (~36 per patient). Tumor cells were detected by immunohistochemistry in 24 lymph nodes from 12 patients (30%). Neoplasic cells were detected as a single or cluster tumor cells. Tumor (p=0.002), venous (p=0.016), lymphatic (p=0.006) and perineural invasions (p=0.04), as well as peritumoral lymphocytic response (p=0.012) were correlated to CK-positive immunostaining tumor cells in originally negative lymph nodes by H&E. The histologic stage of two patients was upstaged from stage IB to stage IIA. Four of the 28 CK-negative patients (14.3%) and three among 12 CK-positive patients (25%) had disease recurrence (p=0.65). The CK-immunostaining is an effective method for detecting occult tumor cells in lymph nodes and may be recommended to precisely determine tumor stage. It may be useful as supplement to H&E routine to provide better pathological staging. A presença de metástase em linfonodos é um dos indicadores prognósticos mais importantes no câncer gástrico.

    To study micrometastases in lymph nodes from patients with node-negative gastric carcinoma by routine histologic examination and discuss their prognostic significance and the relationship between micrometastases and each of the clinicopathologic factors. Methods: A total of 1245 perigastric lymph nodes from 105 patients with node-negative gastric carcinoma was immunohistochemically detected using a monoclonal antibody against low molecular weight cytokeratin AE1. The characteristics of the micrometastases, their related factors and effect on patients' survival after surgery were analysed and tested with statistical methods. Results: Micrometastases were observed in 81 lymph nodes (6.5%) of 31 patients (29.5%). The incidence of lymph node micrometastases was significantly higher in the diffuse type (41.5%) than in the intestinal type gastric carcinoma (17.6%, P<0.01, x2 test). In addition, the presence of micrometastases was closely correlated with the size and invasion depth of the primary tumor, but had no relation to patient's age, sex and the location of primary tumor. The patients with micrometastases had significantly worse prognosis shown by Log-rank test. Their five-year survival rate after surgery was 61.29%; for those without micrometastases the rate was 82.43%, P=0.0116. When the number of patient's lymph nodes with micrometastases was three or more, the five-year survival rate of these patients was much lower (41.67%, P=0.0012). Conclusion: The detection of lymph node micrometastases is necessary to more accurately determine the prognosis and clinical staging of patients with node- negative gastric carcinoma by routine histologic examination. The presence of micrometastases may be regarded as one of the clues in adjuvant therapy of those patients.

    The majority of women diagnosed with lymph node-negative breast cancer are unnecessarily treated with damaging chemotherapeutics after surgical resection. This highlights the importance of understanding and more accurately predicting patient prognosis. In the present study, we define the transcriptional networks regulating well-established prognostic gene expression signatures. We find that the same set of transcriptional regulators consistently lie upstream of both 'prognosis' and 'proliferation' gene signatures, suggesting that a central transcriptional network underpins a shared phenotype within these signatures. Strikingly, the master transcriptional regulators within this network predict recurrence risk for lymph node-negative breast cancer better than currently used multigene prognostic assays, particularly in estrogen receptor-positive patients. Simultaneous examination of p16(INK4A) expression, which predicts tumours that have bypassed cellular senescence, revealed that intermediate levels of p16(INK4A) correlate with an intact pRB pathway and improved survival. A combination of these master transcriptional regulators and p16(INK4A), termed the OncoMasTR score, stratifies tumours based on their proliferative and senescence capacity, facilitating a clearer delineation of lymph node-negative breast cancer patients at high risk of recurrence, and thus requiring chemotherapy. Furthermore, OncoMasTR accurately classifies over 60% of patients as 'low risk', an improvement on existing prognostic assays, which has the potential to reduce overtreatment in early-stage patients. Taken together, the present study provides new insights into the transcriptional regulation of cellular proliferation in breast cancer and provides an opportunity to enhance and streamline methods of predicting breast cancer prognosis.

    Stage migration is an accepted explanation for the association between lymph node (LN) yield and outcome in colon cancer. To investigate whether the alternative thesis of immune response is more likely, we performed a retrospective study. We enrolled 239 cases of node negative cancers, which were categorized according to the number of LNs with diameters larger than 5 mm (LN5) into the groups LN5-very low (0 to 1 LN5), LN5-low (2 to 5 LN5), and LN5-high (≥6 LN5). Significant differences were found in pT3/4 cancers with median survival times of 40, 57, and 71 months (P = .022) in the LN5-very low, LN5-low, and LN5-high groups, respectively. Multivariable analysis revealed that LN5 number and infiltration type were independent prognostic factors. LN size is prognostic in node negative colon cancer. The correct explanation for outcome differences associated with LN harvest is probably the activation status of LNs. Copyright © 2015 Elsevier Inc. All rights reserved.

    To evaluate non-sentinel lymph node (LN) status after sentinel lymph node biopsy (SNB) in patients with breast cancer and to identify the predictive factors for disease failure. From January 2006 to December 2007, axillary lymph node (ALN) dissection after SNB was performed for patients with primary invasive breast cancer who had no clinical evidence of LN metastasis. A total of 320 patients were treated with breast-conserving surgery and radiotherapy. The median age of patients was 48 years, and the median follow-up time was 72.8 months. Close resection margin (RM) was observed in 13 patients. The median number of dissected SNB was two, and that of total retrieved ALNs was 11. Sentinel node accuracy was 94.7%, and the overall false negative rate (FNR) was 5.3%. Eleven patients experienced treatment failure. Local recurrence, regional LN recurrence, and distant metastasis were identified in 0.9%, 1.9%, and 2.8% of these patients, respectively. Sentinel LN status were not associated with locoregional recurrence (p > 0.05). Close RM was the only significant factor for disease-free survival (DFS) in univariate and multivariate analysis. The 5-year overall survival, DFS, and locoregional DFS were 100%, 96.8%, and 98.1%, respectively. In this study, SNB was performed with high accuracy and low FNR and high locoregional control was achieved.

    Full Text Available Objective. The aim of this study was to identify the risk factors associated with central lymph node metastasis (CLNM in patients with clinically node-negative conventional papillary thyroid carcinoma (cN0 CPTC. Methods. A total of 190 cN0 CPTC patients who underwent thyroidectomy with prophylactic central neck dissection (pCND in the Department of General Surgery at Guangdong General Hospital between March 2014 and December 2015 were assessed retrospectively. The relations of CLNM with clinicopathologic characteristics of cN0 CPTC were analyzed by univariate and multivariate logistic regression. Results. The incidence of CLNM in patients with cN0 CPTC was 63.2% (120 of 190 cases. Univariate analysis showed that age 2 cm (P=0.009, multifocality (P=0.001, and bilaterality (P=0.000 were significantly associated with the increased incidence of CLNM in cN0 CPTC. No significant correlations were found between CLNM and other variables such as gender (P=0.150, capsular invasion (P=0.973, extrathyroidal invasion (P=0.616, and lymphadenectomy (P=0.062. Multivariate logistic regression analysis revealed that age 2 cm (P=0.025, and bilaterality (P=0.000 were independent risk factors of CLNM in patients with cN0 CPTC. Conclusions. Metastatic disease to central compartment lymph nodes is prevalent in patients with cN0 CPTC. Age 2 cm, and bilaterality are independent risk factors of CLNM, which allow for selective CND in patients with cN0 CPTC.

    At the moment, positive sentinel lymph node dissection (SLND) of the axilla is followed by axillary lymph node dissection (ALND) as standard of care. Recent data proves that omitting ALND after positive SLND in clinically lymph node-negative early stage breast cancer patients is feasible with low recurrence rates. The well known effect of radiotherapy to destroy occult tumor cells highly contributes to these results as a large extent of level I and II lymph nodes are unavoidably included in standard tangential radiation treatment fields. Reviewing the up to date published data on axillary lymph node treatment with radiotherapy, we hypothesize that full dosage coverage of level I and II of the axilla in early stage breast cancer will improve outcome and should be further evaluated.

    Full Text Available INTRODUCTION: Although lymph node negative (LN- breast cancer patients have a good 10-years survival (∼85%, most of them still receive adjuvant therapy, while only some benefit from this. More accurate prognostication of LN- breast cancer patient may reduce over- and under-treatment. Until now proliferation is the strongest prognostic factor for LN- breast cancer patients. The small molecule microRNA (miRNA has opened a new window for prognostic markers, therapeutic targets and/or therapeutic components. Previously it has been shown that miR-18a/b, miR-25, miR-29c and miR-106b correlate to high proliferation. METHODS: The current study validates nine miRNAs (miR-18a/b miR-25, miR-29c, miR-106b, miR375, miR-424, miR-505 and let-7b significantly correlated with established prognostic breast cancer biomarkers. Total RNA was isolated from 204 formaldehyde-fixed paraffin embedded (FFPE LN- breast cancers and analyzed with quantitative real-time Polymerase Chain Reaction (qPCR. Independent T-test was used to detect significant correlation between miRNA expression level and the different clinicopathological features for breast cancer. RESULTS: Strong and significant associations were observed for high expression of miR-18a/b, miR-106b, miR-25 and miR-505 to high proliferation, oestrogen receptor negativity and cytokeratin 5/6 positivity. High expression of let-7b, miR-29c and miR-375 was detected in more differentiated tumours. Kaplan-Meier survival analysis showed that patients with high miR-106b expression had an 81% survival rate vs. 95% (P = 0.004 for patients with low expression. CONCLUSION: High expression of miR-18a/b are strongly associated with basal-like breast cancer features, while miR-106b can identify a group with higher risk for developing distant metastases in the subgroup of Her2 negatives. Furthermore miR-106b can identify a group of patients with 100% survival within the otherwise considered high risk group of patients with

    MALAT1 (metastasis associated lung adenocarcinoma transcript1) is a conserved long non-coding RNA, known to regulate gene expression by modulating transcription and post-transcriptional pre-mRNA processing of a large number of genes. MALAT1 expression is deregulated in various tumors, including breast cancer. However, the significance of such abnormal expression is yet to be fully understood. In this study, we demonstrate that regulation of aggressive breast cancer cell traits by MALAT1 is not predicted solely based on an elevated expression level but is context specific. By performing loss- and gain-of-function studies, both under in vitro and in vivo conditions, we demonstrate that MALAT1 facilitates cell proliferation, tumor progression and metastasis of triple-negative breast cancer (TNBC) cells despite having a comparatively lower expression level than ER or HER2-positive breast cancer cells. Furthermore, MALAT1 regulates the expression of several cancer metastasis-related genes, but displays molecular subtype specific correlations with such genes. Assessment of the prognostic significance of MALAT1 in human breast cancer (n=1992) revealed elevated MALAT1 expression was associated with decreased disease-specific survival in ER negative, lymph node negative patients of the HER2 and TNBC molecular subtypes. Multivariable analysis confirmed MALAT1 to have independent prognostic significance in the TNBC lymph node negative patient subset (HR=2.64, 95%CI 1.35- 5.16, p=0.005). We propose that the functional significance of MALAT1 as a metastasis driver and its potential use as a prognostic marker is most promising for those patients diagnosed with ER negative, lymph node negative breast cancer who might otherwise mistakenly be stratified to have low recurrence risk.

    This study investigated whether intraoperative assessment of SLN status in patients with clinically node-negative breast cancer was improved using touch imprint immunohistochemistry. Each SLN was cut into slices 2mm thick and evaluated intraoperatively by touch imprint cytology with Papanicolaou staining until the end of 2005, or by a combination of Papanicolaou staining and immunostaining with an anti-cytokeratin antibody from early 2006. When intraoperative cytology of SLN in 85 patients who were clinically node-negative was evaluated with Papanicolaou staining, 81 patients were diagnosed as negative and four were positive. Intraoperative cytology with Papanicolaou staining had a sensitivity of 30%, specificity of 99%, false-negative rate of 70%, false-positive rate of 1.3%, and accuracy of 90.6%. When intraoperative cytology was done with immunohistochemistry plus Papanicolaou staining for SLN evaluation, 92 patients were diagnosed as negative and 17 patients were positive. Intraoperative cytology with immunohistochemistry had a sensitivity of 79%, specificity of 98%, false-negative rate of 21%, false-positive rate of 2.2%, and accuracy of 94.5%. Compared with intraoperative cytology using Papanicolaou staining alone, the combination of immunohistochemistry and Papanicolaou staining achieved a significant increase in sensitivity and a significant decrease in the false-negative rate. Intraoperative SLN evaluation by imprint cytology with immunohistochemistry achieves a more accurate diagnosis of metastasis than imprint cytology alone. This combined method is considered useful for deciding whether to perform axillary lymph node dissection.

Our study suggest that lncRNA profiles provide additional prognostic information and may contribute to the identification of early breast...... below 20%, leading to considerable overtreatment, especially in lymph node-negative patients. Seventy percent would be cured by surgery and radiotherapy alone in this group. Thus, precise and early indicators of metastasis are highly desirable to reduce overtreatment. Previous prognostic RNA......-profiling studies have only focused on the protein-coding part of the genome, however the human genome contains thousands of long non-coding RNAs (lncRNAs) and this unexplored field possesses large potential for identification of novel prognostic markers.

    The International Breast Cancer Study Group Trial VIII compared long-term efficacy of endocrine therapy (goserelin), chemotherapy [cyclophosphamide, methotrexate and fluorouracil (CMF)], and chemoendocrine therapy (CMF followed by goserelin) for pre/perimenopausal women with lymph-node-negative breast cancer. From 1990 to 1999, 1063 patients were randomized to receive (i) goserelin for 24 months (n = 346), (ii) six courses of 'classical' CMF (cyclophosphamide, methotrexate, 5-fluorouracil) chemotherapy (n = 360), or (iii) six courses of CMF plus 18 months goserelin (CMF→ goserelin; n = 357). Tumors were classified as estrogen receptor (ER) negative (19%), ER positive (80%), or ER unknown (1%); 19% of patients were younger than 40. Median follow-up was 12.1 years. For the ER-positive cohort, sequential therapy provided a statistically significant benefit in disease-free survival (DFS) (12-year DFS = 77%) compared with CMF alone (69%) and goserelin alone (68%) (P = 0.04 for each comparison), due largely to the effect in younger patients. Patients with ER-negative tumors whose treatment included CMF had similar DFS (12-year DFS CMF = 67%; 12-year DFS CMF→ goserelin = 69%) compared with goserelin alone (12-year DFS = 61%, P= NS). For pre/perimenopausal women with lymph-node-negative ER-positive breast cancer, CMF followed by goserelin improved DFS in comparison with either modality alone. The improvement was the most pronounced in those aged below 40, suggesting an endocrine effect of prolonged CMF-induced amenorrhea.

    Triple negative breast cancer (TNBC) is the most aggressive breast cancer subtype with no targeted treatment available. Our previous study identified 38 TNBC-specific genes with altered expression comparing tumour to normal samples. This study aimed to establish whether DNA methylation contributed to these expression changes in the same cohort as well as disease progression from primary breast tumour to lymph node metastasis associated with changes in the epigenome. We obtained DNA from 23 primary TNBC samples, 12 matched lymph node metastases, and 11 matched normal adjacent tissues and assayed for differential methylation profiles using Illumina HumanMethylation450 BeadChips. The results were validated in an independent cohort of 70 primary TNBC samples. The expression of 16/38 TNBC-specific genes was associated with alteration in DNA methylation. Novel methylation changes between primary tumours and lymph node metastases, as well as those associated with survival were identified. Altered methylation of 18 genes associated with lymph node metastasis were identified and validated. This study reveals the important role DNA methylation plays in altered gene expression of TNBC-specific genes and lymph node metastases. The novel insights into progression of TNBC to secondary disease may provide potential prognostic indicators for this hard-to-treat breast cancer subtype.

    Full Text Available Abstract Background Whether a systemic adjuvant treatment is needed is an area of controversy in patients with node-negative early breast cancer with tumor size of ≤1 cm, including T1mic. Methods We performed a retrospective analysis of clinical and pathology data of all consecutive patients with node-negative T1mic, T1a, and T1b invasive ductal carcinoma who received surgery between Jan 2000 and Dec 2006. The recurrence free survival (RFS and risk factors for recurrence were identified. Results Out of 3889 patients diagnosed with breast cancer, 375 patients were enrolled (T1mic:120, T1a:93, T1b:162. Median age at diagnosis was 49. After a median follow up of 60.8 months, 12 patients developed recurrences (T1mic:4 (3.3%, T1a:2 (2.2%, T1b:6 (3.7%, with a five-year cumulative RFS rate of 97.2%. Distant recurrence was identified in three patients. Age younger than 35 years (HR 4.91; 95% CI 1.014-23.763, p = 0.048 and triple negative disease (HR 4.93; 95% CI 1.312-18.519, p = 0.018 were significantly associated with a higher rate of recurrence. HER2 overexpression, Ki-67, and p53 status did not affect RFS. Conclusions Prognosis of node-negative breast cancer with T1mic, T1a and T1b is excellent, but patients under 35 years of age or with triple negative disease have a relatively high risk of recurrence.

    OBJECTIVES We investigated the role of the 2011 International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society (IASLC/ATS/ERS) classification in predicting occult lymph node metastasis in clinically mediastinal node-negative lung adenocarcinoma. METHODS We reviewed lung adenocarcinoma patients who had clinically N2-negative status, were evaluated by preoperative positron emission tomography combined with computed tomography (PET/CT) and had undergone lobectomy or pneumonectomy at Memorial Sloan Kettering Cancer Center (n = 297). Tumours were classified according to the 2011 IASLC/ATS/ERS classification. The associations between occult lymph node metastasis and clinicopathological variables were analysed using Fisher's exact test and logistic regression analysis. RESULTS Thirty-two (11%) cN0-1 patients had occult mediastinal lymph node metastasis (pN2) whereas 25% of cN1 patients had pN2 disease. Increased micropapillary pattern was associated with increased risk of pN2 disease (P = 0.001). On univariate analysis, high maximum standard uptake value of the primary tumour on PET/CT (P = 0.019) and the presence of micropapillary (P = 0.014) and solid pattern (P = 0.014) were associated with occult pN2 disease. On multivariable analysis, micropapillary pattern was positively associated with risk of pN2 disease (odds ratio = 3.41; 95% confidence intervals = 1.42–8.19; P = 0.006). CONCLUSIONS The presence of micropapillary pattern is an independent predictor of occult mediastinal lymph node metastasis. Our observations have potential therapeutic implications for management of early-stage lung adenocarcinoma. PMID:26377636

    The European Association of Urology (EAU) guidelines advise an elective bilateral lymphadenectomy in clinically node-negative (cN0) patients with high-risk penile carcinoma (≥pT2, G3, or lymphovascular invasion [LVI]). Our aim was to assess prognostic factors for occult metastasis and to determine whether current EAU guidelines accurately stratify patients at high risk. Data of 342 cN0 patients with histologically proven invasive penile squamous cell carcinoma who had undergone the current dynamic sentinel node biopsy (DSNB) protocol were analysed. A complete ipsilateral inguinal lymphadenectomy was only done if the sentinel node was tumour positive. The presence of occult metastasis was established by preoperative ultrasound and tumour-positive fine-needle aspiration cytology, tumour-positive sentinel nodes, and groin metastases during follow-up after a negative DSNB procedure. Median follow-up was 31 mo. Sixty-eight of 342 patients (20%) and 87 of 684 groins (13%) had occult nodal involvement including 6 patients (2%) with a groin metastasis after negative DSNB. Corpus spongiosum invasion, corpus cavernosum invasion, histologic grade, and LVI were each significant prognosticators for occult metastasis on univariate analysis. On multivariate analysis, grade (odds ratio [OR]: 3.3 for intermediate and 4.9 for poor, respectively) and LVI (OR: 2.2) remained predictive factors. In total, 245 patients (72%) were classified high risk according to EAU guidelines. Among them, the incidence of occult metastasis was 23% (57 of 245). A potential limitation of this study is the lack of external review. Histologic grade and LVI are independent prognostic factors for occult metastasis in penile carcinoma. Although both predictors are incorporated into the current EAU guidelines, the stratification of patients needing a lymph node dissection is inaccurate. Approximately 77% of high-risk patients (188 of 245) would have had a negative bilateral inguinal lymphadenectomy. For the

    AIM: To identify the clinicopathological characteristics of lymph node-negative gastric carcinoma, and also to evaluate outcome indicators in the lymph node-negative patients.METHODS: Of 2848 gastric carcinoma patients, 1524(53.5%) were lymph node-negative. A statistical analysis was performed using the Cox model to estimate outcome indicators.RESULTS: There was a significant difference in the recurrence rate between lymph node-negative and lymph node-positive patients (14.4% vs 41.0%, P<0.001).The 5-year survival rate was significantly lower in lymph node-positive than in lymph node-negative patients (31.1% vs 77.4%, P<0.001). Univariate analysis revealed that the following factors influenced the 5-year survival rate: patient age, tumor size, depth of invasion,tumor location, operative type, and tumor stage at initial diagnosis. The Cox proportional hazard regression model revealed that tumor size, serosal invasion, and curability were independent, statistically significant, prognostic indicators of lymph node-negative gastric carcinoma.CONCLUSION: Lymph node-negative patients have a favorable outcome attributable to high curability, but the patients with relatively large tumors and serosal invasion have a poor prognosis. Curability is one of the most reliable predictors of long-term survival for lymph nodenegative gastric carcinoma patients.

    Objective: To investigate the effect of 21-gene recurrence score on adjuvant chemotherapy decisions for patients with estrogen receptor (ER)-positive, epidermal growth factor receptor 2 (HER-2)-negative and lymph node (LN)-negative early stage-breast cancer. Methods: One hundred and forty-eight patients with ER+ , HER-2- and LN- early stage breast cancer were recruited in the Ruijin hospital, Shanghai Jiao Tong University School of Medicine. The 21-gene recurrence score (RS)assay was performed and systemic therapeutic decisions were made before and after knowing the RS results under multidisciplinary discussion. The effects of RS assay and the other influential factors on adjuvant chemotherapy decision were further analyzed. Results: After knowing the RS results, treatment decisions were changed in 26 out of 148 patients(17.6%). Among them, 9 out of 26 patients were not recommended for chemotherapy; 16 of 26 had treatment recommendation changed to chemotherapy, and chemotherapy regimen was changed in the last one patient. Multivariate analysis showed that RS, age and histological grade were independent factors of decision-making for adjuvant chemotherapy. Conclusion: Our results suggest that 21-gene recurrence score significantly influences decision making for adjuvant chemotherapy in patients with ER+ , HER-2- and LN- early stage breast cancer.

    Objective To evaluate the feasibility and accuracy of sentinel lymph node biopsy(SLNB) in previous axillary node positive breast cancer patients whose axillary nodes turned negative after neoadjuvant chemotherapy(NAC).Methods 147 consecutive breast cancer patients with clinically node-negative after NAC were retrospectively analyzed.These patients underwent SLNB followed by complete axillary lymph node dissection.All patients were proved to be axillary node-positive by fine needle aspiration cytology before NAC.Results The identification rate,false negative rate and accuracy for SLNB was 87.07% (128/147),14.43% (14/97)and 89.06% (114/128)respectively.SLNs were the only positive nodes in 14.84% patients(19/128).The rate of pathologically negative axillary lymph node was 24.50% (36/147),significantly higher in patients who received NAC more than 80% of the total cycles than in those who received NAC less than 80% of the total cycles (40.54% vs 19.09%,P =0.009),and was accompanied with improved identification rate and accuracy of SLNB.The difference of false negative rate (6.82% vs 24.44%,P =0.016) and accuracy (95.31% vs 82.81%,P =0.023) had statistical significance between patients initially in axillary cN1 and in cN2 ~ 3,while no connection was found with the initial size and down-stage of the primary tumor.The identification rate,false negative rate and accuracy were improved in patients with combined Methylene blue and99m Tc-SC than in patients with Methylene blue alone.Conclusions It is technically feasible to perform SLNB in clinically negative-node barest cancer patients after NAC,and the SLNB accuracy remains reasonable.It is possible to maximize the benefits of NAC by using SLNB to stage the axillary lymph nodes in patients who are node-negative after NAC.%目的 探讨新辅助化疗后腋窝降期为临床阴性乳腺癌患者前哨淋巴结活检(sentinel lymph node biopsy,SLNB)的可行性和准确性.方法 对新辅助化

    To identify factors associated with the use of axillary lymph node dissection (ALND) as the initial axillary staging in node-negative breast cancer patients undergoing total mastectomy. California Cancer Registry study. Academic research. Women treated with total mastectomy for Tis, T1, or T2 node-negative breast carcinoma treated between January 1, 2004, and December 31, 2008. Proportions of patients who underwent ALND without prior sentinel lymph node dissection were compared by demographic characteristics. Of 18,238 women treated with total mastectomy for Tis, T1, or T2 node-negative breast carcinoma, 35.1% underwent initial axillary staging by ALND without prior sentinel lymph node dissection. On multivariable analyses, patients were significantly more likely to undergo ALND if they had T2 disease or were 65 years or older, were hormone receptor negative, of Hispanic or Asian/Pacific Islander race/ethnicity, of lower socioeconomic quintile, operated on during earlier years of the study period, and not treated by a hospital cancer program approved by the American College of Surgeons. More than one-third of patients in California who underwent total mastectomy for treatment of early-stage node-negative breast carcinoma received ALND without prior sentinel lymph node dissection; furthermore, certain subsets of patients have higher odds of undergoing ALND alone. To avoid the unnecessary morbidity of ALND in early-stage breast carcinoma, further research is required to elucidate how tumor, patient, and system factors can be modified to improve delivery of optimal breast cancer care.

    Full Text Available Osteoporosis has traditionally been considered a disorder of postmenopausal women, but low bone mass and accelerated bone loss can also occur early in life causing premenopausal osteoporosis. There are a few risk factors that increase a woman′s risk of premenopausal osteoporosis, including drugs, hormonal and nutritional factors, and physical in-activity, which need to be identified and managed accordingly. Lifestyle modification is of importance in preventing progressive bone loss in premenopausal women and should be actively encouraged.

    To evaluate the radial displacement of clinical target volume in the patients with node negative head and neck (H and N) cancer and to quantify the relative positional changes compared to that of normal healthy volunteers. Three node-negative H and N cancer patients and fi ve healthy volunteers were enrolled in this study. For setup accuracy, neck thermoplastic masks and laser alignment were used in each of the acquired computed tomography (CT) images. Both groups had total three sequential CT images in every two weeks. The lymph node (LN) level of the neck was delineated based on the Radiation Therapy Oncology Group (RTOG) consensus guideline by one physician. We use the second cervical vertebra body as a reference point to match each CT image set. Each of the sequential CT images and delineated neck LN levels were fused with the primary image, then maximal radial displacement was measured at 1.5 cm intervals from skull base (SB) to caudal margin of LN level V, and the volume differences at each node level were quantified. The mean radial displacements were 2.26 ({+-}1.03) mm in the control group and 3.05 ({+-}1.97) in the H and N cancer patients. There was a statistically significant difference between the groups in terms of the mean radial displacement (p = 0.03). In addition, the mean radial displacement increased with the distance from SB. As for the mean volume differences, there was no statistical significance between the two groups. This study suggests that a more generous radial margin should be applied to the lower part of the neck LN for better clinical target coverage and dose delivery.

    Oncotype DX, a gene-expression profiling assay, provides stratification of patients with estrogen-receptor positive, lymph-node-negative early breast cancer into risk groups based on recurrence score, which are associated with distant recurrence and response to chemotherapy. This study aims to determine whether Oncotype DX influences clinicians' treatment decisions, and whether assay results correlate with histologic assessment. Fifty patients with estrogen-receptor positive, node-negative early breast cancer analyzed by Oncotype DX and operated on by two breast surgeons were included. To assess effect on treatment decisions, clinical vignettes were created by retrospective chart review. Physicians were then presented with the clinical vignettes and instructed to make a treatment decisions (i.e., hormone therapy alone versus hormone therapy combined with chemotherapy) both before and after knowledge of the recurrence score. To assess correlation with histologic assessment, a prospective, blinded review of tumor slides was performed by two pathologists. Based on this review, tumors were placed into low, intermediate and high risk groups for comparison with Oncotype DX assay results. Treatment decisions were changed based on Oncotype DX results in 36 and 18% of cases by breast surgeons and medical oncologists, respectively. All tumors categorized as high risk by Oncotype DX were categorized as high risk based on histologic assessment, and 96% of cases categorized as low risk by recurrence score were categorized as low or intermediate risk by histologic assessment. Oncotype DX significantly influences management of estrogen-receptor positive, lymph-node-negative early breast cancer. Further studies are needed to assess association of histologic categorization to assay results. © 2013 Wiley Periodicals, Inc.

    Full Text Available Background: Adjuvant systemic chemotherapy (ASCT in lymph node-negative breast (LN− cancers improves survival. The majority of (LN− patients receive ASCT when the St. Gallen criteria or its modifications are used, as accurate identifiers which patients benefit from ASCT are lacking. This may imply over-treatment in many patients. Aim: To evaluate which patients or primary tumor factors predict ASCT success. Material and method: Retrospective analysis by single and multivariate survival analysis of clinical and tumor characteristics in (LN− breast cancers <55 years, related to ASCT (n = 125 or-not (n = 516. Results: The two patient groups did not differ in age, tumor diameter, grade, type, number of mitoses and other factors. Fourteen-year survival for the ASCT and non-ASCT patients was 83% and 74% (Hazard Ratio = HR = 0.33; p < 0.0001, 9% absolute = 12% relative difference. Subgroup analysis showed that the recurrence-free survival = RFS of ASCT treated vs. non-treated patients differed in patients with grade 1 cancers (p = 0.008, grade 2 cancers (p = 0.004, grades 3 (p = 0.02, tumors under and ≧2 cm (p = 0.001 and 0.0002, oestrogen receptor-positive or -negative tumors (p = 0.003, 0.04, MAI < 10 and ≧10 (p = 0.005, 0.003 and fibrotic focus absent (p = 0.002. With multivariate analysis the most important predictor of ASCT effect was the MAI. In patients with slowly proliferating tumors (MAI < 3 no advantage was found between patients treated-or-not with adjuvant chemotherapy (RFS = 92% and 91%, p = 0.13, p = 0.63 for overall survival, contrasting those with MAI ≧ 3 (p = 0.0001; HR = 0.32, 95% CI 0.18–0.58. Conclusion: MAI is the strongest predictor of adjuvant systemic chemotherapy success. In patients with MAI < 3 (31% of all patients, ASCT does not improve survival.

    Full Text Available Abstract Background The status of the regional nodes is the most important prognostic factor in gastric cancer. There are subgroups of patients with different prognosis even in node-negative patients of gastric cancer. The aim of this study is to analyze the factors influencing the prognosis in Indian patients with node-negative gastric cancer. Methods This was a retrospective analysis of patients who underwent radical gastrectomy in a tertiary cancer centre in India between1991 and 2007. The study group included only patients with histologically node-negative disease. Various clinical, pathological and treatment related factors in this group of patients were analyzed to determine their prognostic ability by univariate and multivariate analyses. Results Among the 417 patients who underwent gastrectomy during this period, 122 patients had node-negative disease. A major proportion of the patients had advanced gastric cancer. The 5-year overall survival and disease-free survival in all node-negative gastric cancer patients was 68.2% and 67.5% respectively. The overall recurrence rate in this group was 27.3%. On univariate analysis, the factors found to significantly influence the disease-free survival were the size, location and presence or absence of serosal invasion of the primary tumor. However, on multivariate analysis, only tumor size more than 3 cm and serosal invasion were found to be independently associated with an inferior survival. Conclusion Serosal invasion and primary tumor size more than 3 cm independently predict a poor outcome in patients with node-negative gastric cancer.

    precocious diagnoses were worldwide reported. Among endocrine and neck surgeons, there is agreement about indications to prophylactic treatment of node-negative "high-risk" patients. A recent trend toward RCLD avoiding radioactive treatment is still debated, but nevertheless, prophylactic dissections in low-risk cases should be avoided. Prospective randomized trials are needed to evaluate the benefits of different approaches and allow to drawn definitive conclusions.

    Objective: The aim of this study was to investigate Cathepsin-D (Cath-D) expression in different location and its relationship with prognosis in the axillary lymph nodes negative (ANN) breast cancer patients. Methods: Cath-D expression in 192 cases of breast carcinoma were examined by immunohistochemistry. Depending on different parts of expression, three evaluating methods were used, compared and analysed. Results: The positive rate of Cath-D expression in ANN breast cancer with poor prognosis group and axillary nodes positive (ANP) group were significantly higher than that in ANN breast cancer with good prognosis group (x2=23.20, P0.05). Cath-D expression in stromal cells had no statistical difference among the three groups (x2=1.56, P>0.05). When the Cath-D expression in cancer and stromal cells were counted into the positive rate, it was near the same (u1=0.47, u2=1.41, P>0.05). Conclusion: These results suggest that Cath-D expression is one of the powerful prognostic markers in ANN breast cancer. It's a reliable, practical, and convenient method to observe and evaluate Cath-D expression in cancer cells.

    The timing of the sentinel lymph node biopsy (SNB) is controversial in clinically node negative patients receiving neoadjuvant chemotherapy (NAC). We studied variation in the timing of axillary staging in breast cancer patients who received NAC and the subsequent axillary treatment in The Netherlands. Patients diagnosed with clinically node negative primary breast cancer between 1st January 2010 and 30th June 2013 who received NAC and SNB were selected from the Netherlands Cancer Registry. Data on patient and tumour characteristics, axillary staging and treatment were analysed. Two groups were defined: (1) patients with SNB before NAC (N=980) and (2) patients with SNB after NAC (N=203). Eighty-three percent of patients underwent SNB before NAC, with large regional variation (35-99%). The SN identification rate differed for SNBs conducted before and after NAC (98% versus 95%; p=0.032). A lower proportion of patients had a negative SNB when assessed before NAC compared to after (54% versus 67%; p=0.001). The proportion of patients receiving any axillary treatment was higher for those with SNB before NAC than after (45% versus 33%; p=0.006). In conclusion, variation exists in the timing of SNB in clinical practice in The Netherlands for clinically node negative breast cancer patients receiving NAC. The post-NAC SN procedure is, despite some lower SN identification rate, associated with a significantly less frequent axillary treatment and thus with less expected morbidity. The effect on recurrence rate is not yet clear. Patients in this registry will be followed prospectively for long-term outcome. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Five hundred six consecutive cases of ductal infiltrating carcinoma of the breast (T1-T2,N0,M0) were evaluated to define the frequency of peritumoral lymphatic invasion (PLI) and verify its possible prognostic significance. Histologically, PLI was characterized by the presence of neoplastic emboli within vascular lumina lined by recognizable endothelial cells, adjacent to but outside the margins of the carcinoma. In routine histopathologic assessment the frequency of PLI was 68% whereas in a randomly selected group of 234 reviewed cases the frequency rose to 20%. Patients with routinely evaluated PLI had a worse prognosis than those without PLI with reference both to disease-free survival (P = 0.0001) and total survival rates (P = 0.0001). The difference for local recurrences was prognostically highly significant (P = 0.0001) and also significant for the development of metastases (P = 0.0576). In the reviewed material the difference in prognosis between PLI-positive and PLI-negative cases was not confirmed for total survival whereas the significance for the disease-free interval persisted. The assessment of PLI, carried out following strict histopathologic criteria, appears to select a group of node-negative breast cancer patients who have an increased risk of recurrences and might benefit from a treatment different from that reserved for node-negative and PLI-negative patients.

    Chemoradiation (CRT) is the standard of care in patients with node-positive (cN+) and node-negative (cN0) anal cancer. Depending on the tumor size (T-stage), total doses of 50-60 Gray (Gy) in daily fractions of 1.8-2.0 Gy are usually applied to the tumor site. Inguinal and iliac lymph nodes usually receive a dose of ≥ 45 Gy. Since 2010, our policy has been to apply a reduced total dose of 39.6 Gy to uninvolved nodal regions. This paper provides preliminary results of the efficacy and safety of this protocol. Overall, 30 patients with histologically confirmed and node-negative anal cancer were treated in our department from 2009-2014 with definitive CRT. Histology all cases showed squamous cell carcinoma. A total dose of 39.6 Gy [single dose (SD) 1.8 Gy] was delivered to the iliac/inguinal lymph nodes. The area of the primary tumor received 50-59.4 Gy, depending on the T-stage. In parallel with the irradiation, 5-fluorouracil (5-FU) at a dose of 1000 mg/m{sup 2} was administered by continuous intravenous infusion over 24 h on days 1-4 and 29-32, and mitomycin C (MMC) at a dose of 10 mg/m{sup 2} (maximum absolute dose 14 mg) was administered on days 1 and 29. The distribution of the tumor stages was as follows: T1, n = 8; T2, n = 17; T3 n = 3. Overall survival (OS), local control (LC) of the lymph nodes, colostomy-free survival (CFS), and acute and chronic toxicities were assessed. The median follow-up was 27.3 months (range 2.7-57.4 months). Three patients (10.0 %) died, 2 of cardiopulmonary diseases and one of liver failure, yielding a 3-year OS of 90.0 %. Two patients (6.7 %) relapsed early and received salvage colostomies, yielding a 3-year CFS of 93.3 %. No lymph node relapses were observed, giving a lymph node LC of 100 %. According to the Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE V. 4.0), there were no grade IV gastrointestinal or genitourinary acute toxicities. Seven patients showed acute grade III perineal skin toxicity. Acute grade

    There are divergent opinions regarding the use of ovarian function suppression or ablation (hereafter, OFS) in hormone receptor positive early breast cancer patients. In order to clarify the survival benefit of OFS, a meta-analysis was performed. The result is that use of OFS was more effective than no OFS on DFS (the pooled relative risk (pRR) = 0.86; 95% CI: 0.75-0.96) and on OS (pRR = 0.79; 95% CI: 0.70-0.89). In subgroup analysis, we found that increased DFS was positively associated with patients who had received chemotherapy (pRR = 0.85; 95% CI: 0.74-0.96), who were lymph node negative (pRR = 0.74; 95% CI: 0.61-0.91) and were less than 40 years old (pRR = 0.71; 95% CI: 0.59-0.83). There was a significant difference in OS between the groups receiving chemotherapy (pRR = 0.73; 95% CI: 0.58-0.89) or for patients less than 40 years old (pRR = 0.52; 95% CI: 0.18-0.87). The use of OFS also produces statistical differences in the occurrence of the side-effects; severe hot flashes (pRR = 2.32; 95% CI: 1.36-3.97), and hypertension (pRR = 1.54; 95% CI: 1.12-2.12). In general, OFS should be considered as one treatment for hormone receptor positive premenopausal early breast cancer patients who have received chemotherapy and are less than 40 years old. We also should pay attention to the side-effects and weigh the advantages and disadvantages before deciding on using OFS.

    Full Text Available Abstract Background Given the large number of genes purported to be prognostic for breast cancer, it would be optimal if the genes identified are not confounded by the continuously changing systemic therapies. The aim of this study was to discover and validate a breast cancer prognostic expression signature for distant metastasis in untreated, early stage, lymph node-negative (N- estrogen receptor-positive (ER+ patients with extensive follow-up times. Methods 197 genes previously associated with metastasis and ER status were profiled from 142 untreated breast cancer subjects. A "metastasis score" (MS representing fourteen differentially expressed genes was developed and evaluated for its association with distant-metastasis-free survival (DMFS. Categorical risk classification was established from the continuous MS and further evaluated on an independent set of 279 untreated subjects. A third set of 45 subjects was tested to determine the prognostic performance of the MS in tamoxifen-treated women. Results A 14-gene signature was found to be significantly associated (p Conclusion The 14-gene signature is significantly associated with risk of distant metastasis. The signature has a predominance of proliferation genes which have prognostic significance above that of Ki-67 LI and may aid in prioritizing future mechanistic studies and therapeutic interventions.

    Objective:To investigate the expressions of plasminogen activator inhibitor type 1(PAI-1),C-erbB-2,VEGF and Ki-67 by immunohistostaining and then to evaluate the prognostic value of PAJ-1 in node-negative breast cancer,Methods:The study included a retrospective series of 62 female patients with axillary lymph node-negative breast cencer.Expressions of PAI-1,C-erbB-2,VEGF and Ki-67 were determined by immunohistostaining on formalin-fixed paraffin-embedded tissue sections from these patients after a median follow-up of 69 months(range 22-117 months).Correlations with well known clinicopathologic factors were assessed and multivariate survival analyses were performed.Results:High PAI-1 level was positively associated with high histologic grade of the tumors.Disease-free survival(DFS)was significantly shorter for the patients with moderate to intensive expression of PAI-1 lban for those with negative(X2=25.46,P<0.001:X2=23.07,P<0.001)to mild expression(X2=19.75,P<0.001:X2=17.40.P<0.001).Although on univariate analysis of the prognostic factors,tumor size,location of primary tumor and age as well as expressions of PAI-1,VEGF and Ki-67 were all significantly prognostic factors for DFS(P<0.05),PAI-1 was the only independent prognostic factor on multivariate analysis(P<0.0001;hazard ratio[HR].4.041:95% confidence intewal[CI],1.928-8.468).Conclusion:These results of the current study indicate that intermediate or high expression of PAI-1 represents a strong and independent unfavorable prognostic factor for the development of recurrence or metastases in axillary node-negative breast cancer.

    Full Text Available Abstract Background Elevated levels of matrix metalloproteinases have been found to associate with poor prognosis in various carcinomas. This study aimed at evaluating plasma levels of MMP1, MMP8 and MMP13 as diagnostic and prognostic markers of breast cancer. Methods A total of 208 breast cancer patients, of which 21 with inflammatory breast cancer, and 42 healthy controls were included. Plasma MMP1, MMP8 and MMP13 levels were measured using ELISA and correlated with clinicopathological characteristics. Results Median plasma MMP1 levels were higher in controls than in breast cancer patients (3.45 vs. 2.01 ng/ml, while no difference was found for MMP8 (10.74 vs. 10.49 ng/ml. ROC analysis for MMP1 revealed an AUC of 0.67, sensitivity of 80% and specificity of 24% at a cut-off value of 4.24 ng/ml. Plasma MMP13 expression could not be detected. No correlation was found between MMP1 and MMP8 levels. We found a trend of lower MMP1 levels with increasing tumour size (p = 0.07; and higher MMP8 levels with premenopausal status (p = 0.06 and NPI (p = 0.04. The median plasma MMP1 (p = 0.02 and MMP8 (p = 0.007 levels in the non-inflammatory breast cancer patients were almost twice as high as those found in the inflammatory breast cancer patients. Intriguingly, plasma MMP8 levels were positively associated with lymph node involvement but showed a negative correlation with the risk of distant metastasis. Both controls and lymph node negative patients (pN0 had lower MMP8 levels than patients with moderate lymph node involvement (pN1, pN2 (p = 0.001; and showed a trend for higher MMP8 levels compared to patients with extensive lymph node involvement (pN3 and a strong predisposition to distant metastasis (p = 0.11. Based on the hypothesis that blood and tissue protein levels are in reverse association, these results suggest that MMP8 in the tumour may have a protective effect against lymph node metastasis. Conclusion In summary, we observed differences in MMP1

    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 (n = 41) and positive (n = 35) lymph node status matched for possible confounding factors were subjected to laser microdissection and gene expression data generated. Although ANOVA analysis (P .001, fold-change >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 correlate sonographic and mammographic findings with prognostic factors in patients with node-negative invasive breast cancer. Sonographic and mammographic findings in 710 consecutive patients (age range 21-81 years; mean age 49 years) with 715 node-negative invasive breast cancers were retrospectively evaluated. Pathology reports relating to tumour size, histological grade, lymphovascular invasion (LVI), extensive intraductal component (EIC), oestrogen receptor (ER) status and HER-2/neu status were reviewed and correlated with the imaging findings. Statistical analysis was performed using logistic regression analysis and intraclass correlation coefficient (ICC). On mammography, non-spiculated masses with calcifications were associated with all poor prognostic factors: high histological grade, positive LVI, EIC, HER-2/neu status and negative ER. Other lesions were associated with none of these poor prognostic factors. Hyperdense masses on mammography, the presence of mixed echogenicity, posterior enhancement, calcifications in-or-out of masses and diffusely increased vascularity on sonography were associated with high histological grade and negative ER. Associated calcifications on both mammograms and sonograms were correlated with EIC and HER-2/neu overexpression. The ICC value for the disease extent was 0.60 on mammography and 0.70 on sonography. Several sonographic and mammographic features can have a prognostic value in the subsequent treatment of patients with node-negative invasive breast cancer. Radiologists should pay more attention to masses that are associated with calcifications because on both mammography and sonography associated calcifications were predictors of positive EIC and HER-2/neu overexpression.

    Ki67 labeling index (Ki67 LI) is a measure of tumor proliferation. In breast cancer, evidence supporting its prognostic value is clear and its predictive value for response to treatment finds some benefits. However studies of Ki67 LI as a predictive marker in early breast cancer are still limited worldwide and there is no data in Thailand. To assess the predictive value of Ki67 expression for adjuvant chemotherapy in patients with node-negative, hormone receptor-positive breast cancer The authors retrospectively evaluated 127 diagnosed early breast cancer with node-negative, hormone receptor-positive patients and receiving adjuvant systemic treatment at Siriraj hospital. Disease free survival (DFS) was compared with the log-rank test according to Ki67 LI and adjuvant systemic treatment (chemoendocrine therapy and endocrine therapy alone). At a median follow-up of 3.3 years. The 5-year DFS rate was 79% for patients with low Ki67 expression and 75% for patients with high Ki67 expression. Of the 127 patients, 56 (44.1%) received chemoendocrine therapy and 71 (55.9%) were treated with endocrine therapy alone. There was no different effect of DFS among those receiving adjuvant endocrine therapy alone and those receiving adjuvant chemoendocrine therapy depending on Ki67 expression. Among patients with node-negative, hormone receptor-positive breast cancer, a high Ki67 LI had worse DFS trend than a low Ki67 LI but the Ki67 LI did not predict the efficacy of adjuvant chemotherapy.

    Risk assessment and treatment choice remain a challenge in early non-small-cell lung cancer (NSCLC). Alternative splicing is an emerging source for diagnostic, prognostic and therapeutic tools. Here, we investigated the prognostic value of the actin cytoskeleton regulator hMENA and its isoforms, hMENA11a and hMENAΔv6, in early NSCLC. The epithelial hMENA11a isoform was expressed in NSCLC lines expressing E-CADHERIN and was alternatively expressed with hMENAΔv6. Enforced expression of hMENAΔv6 or hMENA11a increased or decreased the invasive ability of A549 cells, respectively. hMENA isoform expression was evaluated in 248 node-negative NSCLC. High pan-hMENA and low hMENA11a were the only independent predictors of shorter disease-free and cancer-specific survival, and low hMENA11a was an independent predictor of shorter overall survival, at multivariate analysis. Patients with low pan-hMENA/high hMENA11a expression fared significantly better (P≤0.0015) than any other subgroup. Such hybrid variable was incorporated with T-size and number of resected lymph nodes into a 3-class-risk stratification model, which strikingly discriminated between different risks of relapse, cancer-related death, and death. The model was externally validated in an independent dataset of 133 patients. Relative expression of hMENA splice isoforms is a powerful prognostic factor in early NSCLC, complementing clinical parameters to accurately predict individual patient risk. PMID:25373410

    Since its introduction, the sentinel lymph node biopsy (SLNB) has become the standard staging procedure in clinical node-negative melanoma patients. A negative SLNB, however, does not guarantee a recurrence-free survival. Insight into metastatic patterns and risk factors for recurrence in SLNB negative melanoma patients can provide patient tailored guidelines. Data concerning melanoma patients who underwent SLNB between 1996 and 2015 in a single center were prospectively collected. Cox regression analyses were used to determine variables associated with overall recurrence and distant first site of recurrence in SLNB-negative patients. In 668 patients, SLNBs were performed between 1996 and 2015. Of these patients, 50.4 % were male and 49.6 % female with a median age of 55.2 (range 5.7-88.8) years. Median Breslow thickness was 2.2 (range 0.3-20) mm. The SLNB was positive in 27.8 % of patients. Recurrence rates were 53.2 % in SLNB-positive and 17.9 % in SLNB-negative patients (p < 0.001). For SLNB-negative patients, the site of first recurrence was distant in 58.5 %. Melanoma located in the head and neck region (hazard ratio 4.88, p = 0.003) and increasing Breslow thickness (hazard ratio 1.15, p = 0.013) were predictive for distant first site of recurrence in SLNB-negative patients. SLNB-negative patients with a nodular melanoma and ulceration had a recurrence rate of 43.1 %; the site of recurrence was distant in 64 % of these patients. The recurrence rates of SLNB-negative nodular ulcerative melanoma patients approach those of SLNB-positive patients. Stringent follow-up is recommended in this subset of patients.

    The association between surgical extent and prognosis in papillary thyroid carcinoma originating in the isthmus is unclear. We included 233 patients with early-stage, node-negative papillary thyroid cancer originating in the isthmus; 126 were treated by lobectomy plus isthmusectomy with ipsilateral central neck dissection and 97 were treated by total thyroidectomy with bilateral central neck dissection. Subgroup analysis was performed according to tumor size (≤ 1 vs. >1 cm) to evaluate whether tumor size had a significant impact on determining the optimal extent of surgery in our cohort. Total thyroidectomy patients had longer recurrence-free survival (RFS) than those treated by lobectomy plus isthmusectomy. Subgroup analysis showed that this was true only for tumors >1 cm. In multivariate analysis, total thyroidectomy was an independent risk factor for RFS only for tumors >1 cm. Lobectomy plus isthmusectomy may be optimal for early-stage, node-negative papillary thyroid carcinoma originating in the isthmus for tumors ≤ 1 cm; total thyroidectomy might be better for tumors >1 cm.

    Retrospective studies suggest that primary breast cancers lacking estrogen receptor (ER) and progesterone receptor (PR) and not overexpressing human epidermal growth factor receptor 2 (HER2; triple-negative tumors) are particularly sensitive to DNA-damaging chemotherapy with alkylating agents. Patients enrolled in International Breast Cancer Study Group Trials VIII and IX with node-negative, operable breast cancer and centrally assessed ER, PR, and HER2 were included (n = 2,257). The trials compared three or six courses of adjuvant classical cyclophosphamide, methotrexate, and fluorouracil (CMF) with or without endocrine therapy versus endocrine therapy alone. We explored patterns of recurrence by treatment according to three immunohistochemically defined tumor subtypes: triple negative, HER2 positive and endocrine receptor absent, and endocrine receptor present. Patients with triple-negative tumors (303 patients; 13%) were significantly more likely to have tumors > 2 cm and grade 3 compared with those in the HER2-positive, endocrine receptor-absent, and endocrine receptor-present subtypes. No clear chemotherapy benefit was observed in endocrine receptor-present disease (hazard ratio [HR], 0.90; 95% CI, 0.74 to 1.11). A statistically significantly greater benefit for chemotherapy versus no chemotherapy was observed in triple-negative breast cancer (HR, 0.46; 95% CI, 0.29 to 0.73; interaction P = .009 v endocrine receptor-present disease). The magnitude of the chemotherapy effect was lower in HER2-positive endocrine receptor-absent disease (HR, 0.58; 95% CI, 0.29 to 1.17; interaction P = .24 v endocrine receptor-present disease). The magnitude of benefit of CMF chemotherapy is largest in patients with triple-negative, node-negative breast cancer.

    The prognosis of patients with stage II-III Human Epidermal growth factor Receptor 2 (HER2)-positive breast cancer has significantly improved since the addition of trastuzumab to (neo-)adjuvant chemotherapy. Several reports have shown that small (≤2 cm), node-negative, HER2-positive tumors have a relatively poor prognosis and these patients increasingly receive trastuzumab-based chemotherapy. We aimed to provide evidence for this approach in a population-based cohort. All T1N0M0 HER2-positive breast cancer patients diagnosed between 2006 and 2012 were identified from the Netherlands Cancer Registry. Patient, tumor, and treatment characteristics were recorded. Kaplan-Meier statistics were used for overall survival (OS) and breast cancer-specific survival (BCSS) estimations overall and in T1a, T1b, and T1c tumors separately. Cox regression analyses were performed to account for imbalances in baseline characteristics between treated and untreated patients. A total of 3512 patients were identified: 385 with T1a, 800 with T1b, and 2327 with T1c tumors. Forty-five percent of patients received chemotherapy and/or trastuzumab: 92 % received both. Chemotherapy and/or trastuzumab significantly improved 8-year OS (95 vs. 84 %; hazard ratio [HR] 0.29; 95 % confidence interval [CI] 0.21-0.41, P effect remained significant in multivariable analyses (HR 0.35; 95 % CI 0.23-0.52, P effect on OS and BCSS was similar in T1a, T1b, and T1c tumors. Chemotherapy and/or trastuzumab improves OS and BCSS and can be considered in all patients with small node-negative HER2-positive breast cancer.

    Immunological markers improve specificity and accuracy of cell detection, therefore it is important to evaluate their usefulness in improving standard histological procedures. This study investigates whether immunocytochemical techniques increase the accuracy of detection, in axillary lymph nodes, of metastatic cells from infiltrating breast lobular carcinoma (ILC). Fifty cases of ILC reported to be node-negative were selected. New serial sections were cut from a total of 767 lymph nodes, sta...

    Recurrence develops in nearly one-third of patients who undergo complete resection for non-small cell lung cancer (NSCLC). We sought to identify predictors of early recurrence (lung cancer database. Exclusion criteria included carcinoid, adenocarcinoma in situ, and minimally invasive adenocarcinoma histologies, and any induction therapy. Patient demographics, clinical, and pathologic variables were analyzed. Recurrence was confirmed histologically in 86 patients (85%) or radiographically in 16 (15%). Univariable and multivariable logistic regression (C statistic = 0.7) and Cox proportional hazards analyses were performed (p Recurrence was present in 102 patients (19%) and was locoregional in 33 (32%), distant in 40 (39%), and multisite in 29 (29%). T size, tumor histology, tumor grade, smoking status, maximum standardized uptake value, and albumin were not associated with recurrence. Multivariable predictors of recurrence were lymphovascular invasion (odds ratio, 2.48), sublobar resection (odds ratio, 2.37), and age (odds ratio, 0.96). Recurrence was independently associated with lung cancer-specific death (relative risk, 11.78; 95% confidence interval, 5.46 to 25.36; p recurrence rate in R0 resected node-negative T1 to T2b NSCLC. The identification of unique predictors of recurrence is an important step toward defining a patient population that may benefit from adjuvant therapy.

    To evaluate whether visual assessment of T2-weighted imaging (T2WI) or an apparent diffusion coefficient (ADC) could predict lymphovascular invasion (LVI) status in cases with clinically node-negative invasive breast cancer. One hundred and thirty-six patients with 136 lesions underwent MRI. Visual assessment of T2WI, tumour-ADC, peritumoral maximum-ADC and the peritumour-tumour ADC ratio (the ratio between them) were compared with LVI status of surgical specimens. No significant relationship was found between LVI and T2WI. Tumour-ADC was significantly lower in the LVI-positive (n = 77, 896 ± 148 x 10{sup -6} mm{sup 2}/s) than the LVI-negative group (n = 59, 1002 ± 163 x 10{sup -6} mm{sup 2}/s; p < 0.0001). Peritumoral maximum-ADC was significantly higher in the LVI-positive (1805 ± 355 x 10{sup -6} mm{sup 2}/s) than the LVI-negative group (1625 ± 346 x 10{sup -6} mm{sup 2}/s; p = 0.0003). Peritumour-tumour ADC ratio was significantly higher in the LVI-positive (2.05 ± 0.46) than the LVI-negative group (1.65 ± 0.40; p < 0.0001). Receiver operating characteristic curve analysis revealed that the area under the curve (AUC) of the peritumour-tumour ADC ratio was the highest (0.81). The most effective threshold for the peritumour-tumour ADC ratio was 1.84, and the sensitivity, specificity, positive predictive value and negative predictive value were 77 % (59/77), 76 % (45/59), 81 % (59/73) and 71 % (45/63), respectively. We suggest that the peritumour-tumour ADC ratio can assist in predicting LVI status on preoperative imaging. (orig.)

    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

    BACKGROUND: Resection of the primary tumor followed by sentinel node biopsy (SNB) for the clinically N0 patient has been implemented in our Head and Neck University Center. The purpose of this study was to report on the outcome for patients with negative SNB. METHODS: From April 2007 to October...... 2009, 53 consecutive SNB-negative patients with oral cavity squamous cell carcinoma (SCC) T1 to T2 were accrued. Follow-up was done continuously with the most recent examination in October 2011. The location of the sentinel lymph nodes was determined using dynamic and planar lymphoscintigraphy...... and single photon emission CT (SPECT)-CT. Intraoperatively, a hand-held gamma probe was applied. The harvested sentinel lymph nodes underwent histopathologic examination using step-serial sectioning at 150-μm intervals and immunohistochemistry. In the follow-up period, we observed and examined the SNB...

    This study aimed to investigate the prognostic impact of the log odds of positive lymph nodes (LODDS) in colon cancer. Four hundred and forty patients with colon cancer were divided into three each groups according to their lymph node ratio (LNR) and LODDS. Survival analysis was performed. The 5-year overall survival (OS) rate was 70.2%. In univariate analysis age, pT and pN stage, tumour grade, lymphatic, venous and perineural invasion, surgical margin clearance, LNR and LODDS were significantly associated with OS. In multivariate analysis age, surgical margins, perineural invasion and LODDS were found to be independent prognostic factors. In subgroup analysis of patients with an inadequate number of examined lymph nodes (NELN) (n = 76) and node-negative patients (n = 210), LODDS retained its prognostic value, whereas the impact of LNR was not statistically significant (P = 0.063). The overall survival rates of node-negative patients in the LODDS groups 0, 1 and 2 were 81%, 74.2% and 50%, respectively (P = 0.020). LNR and LODDS classifications were both significantly associated with survival in Stage III colon cancer, but only LODDS was an independent prognostic factor. Conventional TNM staging for nodes (pN) and LNR status cannot reliably classify node-negative patients into homogeneous groups. LODDS provides more valuable information than LNR independently of the NELN. Colorectal Disease © 2014 The Association of Coloproctology of Great Britain and Ireland.

    Benign metastasising leiomyoma (BML) is a rare benign disease associated with uterine leiomyoma and history of uterine surgery. It most frequently occurs in premenopausal woman, with a pulmonary localisation, and consisting of multiple nodules. We present an uncommon case of a 69-year-old woman with a single BML of an inguinal lymph node. CT scans of thorax and abdomen excluded other metastasis localisation. The patient was cured with surgical excision of the mass. Lymph node involvement has been reported incidentally in BML literature. Lymphangitic spread can be considered a possible mechanism of BML metastasis.

    In the recent years several studies have shown that about 30% of cases with axillary node-nagative breast cancer suffer relapse of the disease. Our attempt was made to evaluate the most significant prognostic factors to predict this high risk group which may be benefited from adjuvant treatment. For this purpose, we selected 9 patients out of 80 cases of node-negative breast cancer who had been followed up at least for 5 years and had the recurrence of the disease. For comparison, 16 patients from the same group who did not have relapse were selected on a random basis. Histology, receptor status, AgNOR, DNA flow cytometry and various immunohistochemical parameters were compared between the groups with recurrence and that without recurrence. On univariate analysis, tumor size, immunohistochemical expressions of PCNA, MIB-1, c-erbB-2 and S-phase fraction were significantly different between the above two groups. By multivariate analysis, immunohistochemical c-erbB-2 expression (more than 50% of cancer cells) was an independent parameter. As a summary from our studies, c-erbB-2 immunohistochemical staining on paraffin sections might be the best independent prognostic factor in axillary node-negative breast cancers.

    Neoadjuvant chemotherapy (NAC) is the standard treatment for locally advanced breast cancer. It is now being used to treat operable breast cancer to facilitate breast-conserving surgery, but the accuracy of sentinel lymph node biopsy (SLNB) in breast cancer patients receiving NAC remains open to considerable debate. We enrolled 96 patients with stage II-III breast cancer who received NAC from January 2001 to July 2010. All patients underwent breast surgery and SLNB, followed immediately by complete axillary lymph node dissection (ALND). Sentinel lymph nodes were detected with blue dye and radiocolloid injected intradermally just above the tumor and then evaluated with hematoxylin and eosin and immunohistochemical staining. The overall identification rate for SLNB was 87.5% (84/96); the false negative rate (FNR) was 24.5% (12/49); and the accuracy rate was 85.7% (72/84). The FNR was significantly lower in clinically node-negative patients than in node-positive patients before NAC (5.5% vs. 35.5%; p=0.001). Accuracy was also significantly higher in clinically node-negative patients than in node-positive patients before NAC (97.2% vs. 77.1%; p=0.009). The FNR was 27.3% among 46 clinically node-positive patients before NAC who were clinically node-negative after NAC. Among 12 patients with a complete tumor response (CR), the FNR was 0%, compared with 26.1% for 83 patients with a partial response and stable disease (p=0.404). Although associated with a high FNR after NAC, SLNB would have successfully replaced ALND in clinically node-negative patients before NAC and in patients with a CR after NAC.

    2014-05-01

    The Royal College of Pathologists (RCPath) and College of American Pathologists recommend that at least 12 lymph nodes should be harvested for adequate staging of colorectal carcinoma. Just one nodal tumour deposit upstages the malignancy from pN0 to pN1. This is critically important as node-positive patients (pN1) are considered for adjuvant chemotherapy whereas node-negative patients (pN0) may not be. It is not always easy to harvest the required number, especially in patients with rectal carcinoma who may have received neoadjuvant therapy-an increasingly common treatment. The use of neoadjuvant therapy is known to further decrease the number and size of identifiable lymph nodes within specimens, meaning that the lymph node harvest often fails to reach RCPath guidelines. Lymph node revealing solutions consisting of either single chemicals such as alcohol or acetone or compounds have been investigated to help improve the lymph node harvest in difficult specimens, for example, those received following neoadjuvant therapy. Published research evidence reviewed here suggests that lymph node revealing solutions significantly improve lymph node harvesting, and that glacial acetic acid, ethanol, water and formalin is advantageous in comparison with other revealing solutions in that it is safe, cheap, easy to use and relatively quick. However, the quantity of good evidence is limited and the clinical implications of improving lymph node harvesting require further research.

    Purpose: A retrospectivechart review was conducted to determine whether the time interval from breast-conserving surgery to breast irradiation (surgery-radiation therapy interval) in early stage node-negative breast cancer had any detrimental effects on recurrence rates. Methods and Materials: There were 566 patients with T1 to T3, N0 breast cancer treated with breast-conserving surgery and breast irradiation and without adjuvant systemic treatment between 1985 and 1992. The surgery-to-radiation therapy intervals used for analysis were 0 to 8 weeks (201 patients), >8 to 12 weeks (233 patients), >12 to 16 weeks (91 patients), and >16 weeks (41 patients). Kaplan-Meier estimates of time to local recurrence, disease-free survival, distant disease-free survival, cause-specific survival, and overall survival rates were calculated. Results: Median follow-up was 17.4 years. Patients in all 4 time intervals were similar in terms of characteristics and pathologic features. There were no statistically significant differences among the 4 time groups in local recurrence (P=.67) or disease-free survival (P=.82). The local recurrence rates at 5, 10, and 15 years were 4.9%, 11.5%, and 15.0%, respectively. The distant disease relapse rates at 5, 10, and 15 years were 10.6%, 15.4%, and 18.5%, respectively. The disease-free failure rates at 5, 10, and 15 years were 20%, 32.3%, and 39.8%, respectively. Cause-specific survival rates at 5, 10, and 15 years were 92%, 84.6%, and 79.8%, respectively. The overall survival rates at 5, 10, and 15 years were 89.3%, 79.2%, and 66.9%, respectively. Conclusions: Surgery-radiation therapy intervals up to 16 weeks from breast-conserving surgery are not associated with any increased risk of recurrence in early stage node-negative breast cancer. There is a steady local recurrence rate of 1% per year with adjuvant radiation alone.

    AIM: The prognosis of early gastric carcinoma (EGC) is generally excellent after surgery. The presence or absence of lymph node metastasis in EGC is an important prognostic factor. The survival and recurrence rates of node-negative EGC are much better than those of node-positive EGC. This study examined the factors related to lymph node metastasis in EGC to determine the appropriate treatment for EGC.METHODS: We investigated 748 patients with EGC who underwent surgery between January 1985 and December 1999 at the Division of Gastroenterologic Surgery, Department of Surgery, Chonnam National University Hospital. Several clinicopathologic factors were investigated to analyze their relationship to lymph node metastasis: age, sex, tumor location, tumor size, gross type, histologic type, depth of invasion, extent of lymph node dissection, type of operation,and DNA ploidy.RESULTS: Lymph node metastases were found in 75 patients (10.0%). Univariate analysis showed that male sex, tumor size larger than 2.0 cm, submucosal invasion of tumor, histologic differentiation, and DNA ploidy pattern were risk factors for regional lymph node metastasis in EGC patients. However, a multivariate analysis showed that three risk factors were associated with lymph node metastasis:large tumor size, undifferentiated histologic type and submucosal invasion. No statistical relationship was found for age, sex, tumor location, gross type, or DNA ploidy in multivariate analysis. The 5-year survival rate was 94.2% for those without lymph node metastasis and 87.3% for those with lymph node metastasis, and the difference was significant (P<0.05).CONCLUSION: In patients with EGC, the survival rate of patients with positive lymph nodes is significantly worse than that of patients with no lymph node metastasis. Therefore,a standard D2 lymphadenectomy should be performed in patients at high risk of lymph node metastasis: large tumor size, undifferentiated histologic type and submucosal invasion.

    Full Text Available Background. The incidence of premenopausal breast cancer is rising throughout South Asia. Our objective was to determine the role of risk factors associated with Westernization for premenopausal breast cancer in Bangladesh. Methods. We conducted a matched case-control study between January 1, 2007, and December 31, 2010, at four hospitals in Bangladesh. Cases were premenopausal women diagnosed with invasive breast cancer. Controls were premenopausal women with no personal history of breast cancer. Logistic regression was used to calculate the odds ratios (OR for breast cancer. Results. We identified 129 age-matched pairs. The mean age of breast cancer diagnosis was 37.5 years. Each year decrease in the age of menarche significantly increased the risk of breast cancer (OR = 1.67, 95% CI 1.09–2.56, P=0.02. The risk was also increased with a current body mass index of ≥25 kg/m2 (OR = 5.24, 95% CI 1.10–24.9, P=0.04. Age at first childbirth, parity, and breastfeeding were not significantly associated with premenopausal breast cancer risk (P>0.05. Conclusions. Age at menarche and adult weight gain were associated with premenopausal breast cancer risk. Other factors associated with Westernization may not be relevant to premenopausal breast cancer risk in Bangladesh.

    To evaluate the prognostic value of volume-based metabolic parameters measured with {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography (PET) in patients with clinically node-negative (cN0) oral tongue squamous cell carcinoma (OTSCC) as compared with other prognostic factors. In this study, we included a total of 57 patients who had been diagnosed with cN0 tongue cancer by radiologic, ({sup 18}F-FDG PET/CT, and physical examinations. The maximum standardized uptake value (SUVmax), average SUV (SUVavg), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) for primary tumors were measured with ({sup 18}F-FDG PET. The prognostic significances of these parameters and other clinical variables were assessed by Cox proportional hazards regression analysis. In the univariate analysis, pathological node (pN) stage, American Joint Committee on Cancer (AJCC) stage, SUVmax, SUVavg, MTV, and TLG were significant predictors for survival. On a multivariate analysis, pN stage (hazard ratio = 10.555, p = 0.049), AJCC stage (hazard ratio = 13.220, p = 0.045), and MTV (hazard ratio = 2.698, p 0.033) were significant prognostic factors in cN0 OTSCC patients. The patients with MTV {>=} 7.78 cm{sup 3} showed a worse prognosis than those with MTV < 7.78 cm{sup 3} (p = 0.037). The MTV of primary tumor as a volumetric parameter of ({sup 18}F-FDG PET, in addition to pN stage and AJCC stage, is an independent prognostic factor for survival in cN0 OTSCC.

    Full Text Available Abstract Background To examine the role of brachytherapy for aged patients 80 or more in the trend of rapidly increasing number. Methods We examined the outcomes for elderly patients with node negative oral tongue cancer (T1-3N0M0 treated with brachytherapy. The 21 patients (2 T1, 14 T2, and 5 T3 cases ranged in age from 80 to 89 years (median 81, and their cancer was pathologically confirmed. All patients underwent definitive radiation therapy, with low dose rate (LDR Ra-226 brachytherapy (n = 4; median 70Gy, with Ir-192 (n = 12; 70Gy, with Au-198 (n = 1 or with high dose rate (HDR Ir-192 brachytherapy (n = 4; 60 Gy. Eight patients also underwent external radiotherapy (median 30 Gy. The period of observation ranged from 13 months to 14 years (median 2.5 years. We selected 226 population matched younger counterpart from our medical chart. Results Definitive radiation therapy was completed for all 21 patients (100%, and acute grade 2-3 mucositis related to the therapy was tolerable. Local control (initial complete response was attained in 19 of 21 patients (90%. The 2-year and 5-year local control rates were 91%, (100% for T1, 83% for T2 and 80% for T3 tumors after 2 years. These figures was not inferior to that of younger counterpart (82% at 5-year, n.s.. The cause-specific survival rate was 83% and the regional control rate 84% at the 2-years follow-up. However, 12 patients died because of intercurrent diseases or senility, resulting in overall survival rates of 55% at 2 years and 34% at 5 years. Conclusion Age is not a limiting factor for brachytherapy for appropriately selected elderly patients, and brachytherapy achieved good local control with acceptable morbidity.

    The 7th TNM staging system for non-small cell lung cancer (NSCLC) developed by the International Association for the study of Lung Cancer (IASLC) has been applied in Sweden since the beginning of the year 2010. The aim of this retrospective study was to evaluate the prognostic role of the 7th TNM staging system in a surgical Swedish patient cohort with node-negative NSCLC. We collected data from stage I patients (pT1-2 pN0, 6th TNM system) who underwent surgery for NSCLC at Karolinska University Hospital from 1987 to 2002. Tumors were restaged according to the 7th TNM version. Cox multivariate survival analysis was implemented in order to determine the prognostic impact of pathological stage when classified according to either the 6th or the 7th TNM systems. The patient population consisted of 452 subjects. Tumor size was ≤ 3 cm in 51% of cases. The predominant histology was adenocarcinoma (53%) and lobectomy was the most common surgical procedure (82% of patients). The five-year survival rate in patients with stage IA vs. IB (6th TNM) was 62% vs. 51%, respectively (log-rank p = 0.036). Corresponding figures for the 7th TNM system were 70% in stage IA-T1a, 51% in stage IA-T1b, 54% in stage IB, 51% in stage IIA and 35% in stage IIB (log-rank p = 0.002). On multivariate analysis, adjusted by age, gender, histology, kind of surgery, grade of differentiation and smoking status, pathological stage was an independent prognostic factor if classified according to the 7th TNM version (p = 0.001), but not if scored according to the 6th TNM edition (p = 0.090). The 7th TNM classification system is a more accurate predictor of prognosis in stage I operated patients than the old classification. The new system should be implemented even on retrospective cohorts especially when investigating the prognostic implication of the expression of molecular biomarkers.

    We evaluated whether proliferating cell nuclear antigen (PCNA) immunohistochemistry with antigen retrieval could be used as a measure of cell proliferation in archival, formalin-fixed, paraffin-embedded tissues and whether the staining results have long-term prognostic significance in axillary node-negative breast cancer. Primary tumor samples obtained from 109 axillary-node-negative breast cancer cases were used for the study. The best staining results were obtained with the 19A2 antibody after microwave heating in a solution of saturated lead thiocyanate. Using this method, there was a significant correlation (linear regression, r = 0.580, P treatment may offer a useful alternative to DNA flow cytometry for the analysis of cell proliferation activity from formalin-fixed, paraffin-embedded breast carcinomas.

    Purpose: To inform radiation treatment planning for clinically staged, node-negative bladder cancer patients by identifying clinical factors associated with the presence and location of occult pathologic pelvic lymph nodes. Methods and Materials: The records of patients with clinically staged T1-T4N0 urothelial carcinoma of the bladder undergoing radical cystectomy and pelvic lymphadenectomy at a single institution were reviewed. Logistic regression was used to evaluate associations between preoperative clinical variables and occult pathologic pelvic or common iliac lymph nodes. Percentages of patient with involved lymph node regions entirely encompassed within whole bladder (perivesicular nodal region), small pelvic (perivesicular, obturator, internal iliac, and external iliac nodal regions), and extended pelvic clinical target volume (CTV) (small pelvic CTV plus common iliac regions) were calculated. Results: Among 315 eligible patients, 81 (26%) were found to have involved pelvic lymph nodes at the time of surgery, with 38 (12%) having involved common iliac lymph nodes. Risk of occult pathologically involved lymph nodes did not vary with clinical T stage. On multivariate analysis, the presence of lymphovascular invasion (LVI) on preoperative biopsy was significantly associated with occult pelvic nodal involvement (odds ratio 3.740, 95% confidence interval 1.865-7.499, P<.001) and marginally associated with occult common iliac nodal involvement (odds ratio 2.307, 95% confidence interval 0.978-5.441, P=.056). The percentages of patients with involved lymph node regions entirely encompassed by whole bladder, small pelvic, and extended pelvic CTVs varied with clinical risk factors, ranging from 85.4%, 95.1%, and 100% in non-muscle-invasive patients to 44.7%, 71.1%, and 94.8% in patients with muscle-invasive disease and biopsy LVI. Conclusions: Occult pelvic lymph node rates are substantial for all clinical subgroups, especially patients with LVI on biopsy. Extended

    Sentinel lymph node biopsy (SLNB) has become an accepted standard of care to stage the axilla for clinically node-negative early stage breast cancer. In experienced hands, studies have shown an acceptable rate of identification of the sentinel lymph node (SLN) with blue dye only. Lymphazurin is occasionally associated with severe allergic reaction, including anaphylaxis and death. The use of methylene blue alone as a method of identifying the SLN in breast cancer has been reported once previously in the literature. Methylene blue may be an acceptable alternative with fewer deleterious side effects. Medical records of patients, who underwent sentinel node mapping between September 2003 and March 2005 by two surgeons at an academic medical center were reviewed. SLN mapping was performed by periareolar injection of 5 cc of 1% methylene blue. All patients with positive SLNs underwent completion axillary node dissection. During the study period, 141 consecutive patients with clinically node-negative axillas and without evidence of inflammatory breast cancer underwent SLNB with injection of methylene blue only. A SLN was identified in 136 of 141 patients (96.5%). Thirty-three of 136 SLNs (24%) harbored metastatic disease. No cases of anaphylaxis were noted. In experienced hands, methylene blue alone is a highly sensitive method of detecting SLNs. Avoiding the greater frequency of allergic reactions seen with lymphazurin is an important advantage of methylene blue.

  12. Intramammary lymph nodes.

    1983-05-15

    Radiographic, gross, and histopathologic studies on 158 whole breasts with primary operable carcinoma revealed intramammary lymph nodes in 28%, and of these breasts, 10% contained a metastatic deposit of carcinoma. Cancerous and noncancerous nodes were found in all quadrants of the breast with the positive ones being in the same quadrant as the carcinoma only 50% of the time. There was no demonstrable connection with the usual lymphatic drainage of the breast. With Stage II carcinoma, positive intramammary lymph nodes had no direct effect on prognosis, merely representing advanced disease and indicating a greater likelihood of axillary metastatic disease. There was a trend toward poorer prognosis in Stage I lesions with positive intramammary lymph nodes. This may indicate the Stage I carcinomas that have a similar prognosis as Stage II tumors. Conceivably, a Stage Ia, positive intramammary lymph node(s) but normal axillary lymph nodes, could be defined and used.

    Background: In the treatment of breast cancer, the indication for adjuvant systemic treatment was extended also to nodal negative tumor stages in the last years. For that reason, the indicator status of axillary dissection lost some of its importance. Therefore, in node negative patients, the necessity of axillary dissection and the use of definitive axillary radiotherapy, which causes less morbidity, may be reconsidered. Methods: In a review of the related literature, we present international treatment experiences related to axillary dissection, axillary radiotherapy and `sentinel node dissection` (SLND). In addition, our long-term experiences in 19 patients with clinically negative axillary nodes treated by conservative surgery without axillary dissection but axillary radiotherapy, are reported. Results: The median rate of axillary recurrences with axillary radiotherapy is 2.0%, the regional (supraclavicular and retrosternal) recurrence rate 2.7%. With axillary dissection, axillary recurrences occur in 1 to 2%, in nodal negative stages in 0 to 1%, the median regional recurrence rate is 2.2%. A meta-analysis presented in 1995 by the Early Breast Cancer Study Group showed no significant difference in the regional recurrence rate or the overall survival between axillary dissection and axillary radiotherapy. With SLND, usually only one axillary node is excised. With the help of molecular and immunhistochemical methods, SLNA may predict axillary involvement with high precision. Conclusions: Definitive radiotherapy of the axilla is a valid treatment option for patients without palpable axillary nodes with the potential advantage of being less cost intensive and better tolerated. If the indication for systemic therapy is no more dependent on the axillary status, axillary dissection may be replaced by axillary radiotherapy. In small tumors without risk factors and without indication for systemic therapy, SLND seems to be the best treatment option. (orig.) [Deutsch

  14. Diagnosis of osteoporosis in men, premenopausal women, and children.

    Science.gov (United States)

    2004-01-01

    The World Health Organization (WHO) classification of bone mineral density is based on population studies in postmenopausal women. However, the increased use of bone densitometry has raised questions regarding the applicability of this classification to men, premenopausal women, and children. These questions were addressed at the International Society for Clinical Densitometry 2003 Position Development Conference. T-scores can be used and a diagnosis of osteoporosis made for T-scores of -2.5 or less (male reference database) in men age 65 yr and older and in men from 50 to 64 yr of age if other risk factors for fracture are present. The WHO classification should not be applied to premenopausal women. Men and premenopausal women with secondary causes of low bone density or bone loss may be clinically diagnosed with osteoporosis, taking bone density into consideration. In children and adolescents (males and females less than 20 yr of age), there are no densitometric criteria for diagnosing osteoporosis. If Z-scores are -2.0 or less (using pediatric databases of age-matched controls), then a characterization such as "low bone density for chronologic age" is appropriate. In men under 50 yr of age, premenopausal women, and children, Z-scores, not T-scores, should be used when reporting bone density results.

    Full Text Available Abstract Background Tumor length is an important prognostic factor for many carcinomas, but its role in esophageal cancer remained undetermined. The aim of this study was to investigate the effect of tumor length on survival for patients with confined tumors (grade pT1-2 without lymph-node metastases in esophageal squamous cell carcinoma. Methods We enrolled 201 patients with esophageal squamous cell carcinoma (SCC who had undergone surgical resection and been confirmed as pT1-2N0M0. The relationship of tumor length with overall survival was assessed and compared with other factors detailed in the American Joint Committee on Cancer (AJCC tumor, node, metastasis (TNM staging system published in 2009. Results The overall survival (OS rates at 1, 3, and 5 years were 93.0%, 83.7%, and 69.2%, respectively. The tumor length adversely affected OS, with the 5-year rate being 93.5%, 82.0%, 68.6%, 67.9%, 55.3% and 41.1%, respectively for tumor lengths of less than 10 mm, 10 to 20 mm, 20 to 30 mm, 30 to 40 mm, 40 to 50 mm, and greater than 50 mm (PP = 0.04, as did the other current TNM factors. Conclusion Tumor length appears to affect the OS of patients with early-stage esophageal squamous cell carcinoma. It may provide additional prognostic information for the current TNM staging system.

    We recently reported, in a prospective randomized trial, that ultra-staging of patients with colon cancer is associated with significantly improved disease-free survival (DFS) compared with conventional staging. That trial did not control for lymph node (LN) number or adjuvant chemotherapy use. The current international prospective multicenter cooperative group trial (ClinicalTrials.gov identifier NCT00949312; "Ultra-staging in Early Colon Cancer") evaluates the 12-LN quality measure and nodal ultra-staging impact on DFS in patients not receiving adjuvant chemotherapy. Eligibility criteria included biopsy-proven colon adenocarcinoma; absence of metastatic disease; >12 LNs staged pathologically; pan-cytokeratin immunohistochemistry (IHC) of hematoxylin and eosin (H&E)-negative LNs; and no adjuvant chemotherapy. Of 445 patients screened, 203 patients were eligible. The majority of patients had intermediate grade (57.7%) and T3 tumors (64.9%). At a mean follow-up of 36.8 ± 22.1 months (range 0 to 97 months), 94.3% remain disease free. Recurrence was least likely in patients with ≥12 LNs, H&E-negative LNs, and IHC-negative LNs (pN0i-): 2.6% vs 16.7% in the pN0i+ group (p negative colon cancer (≥12 LNs, pN0i-) are unlikely to benefit from adjuvant chemotherapy; 97% remain disease free after primary tumor resection. Both surgical and pathologic quality measures are imperative in planning clinical trials in nonmetastatic colon cancer. Copyright © 2015 American College of Surgeons. All rights reserved.

    Poor prognosis is associated with estrogen- and/or progesterone receptor-positive (ER(+), PGR(+)) premenopausal breast cancer (PM-BC) with high Ki-67 labeling index and extensive axillary lymph node involvement. The role of adjuvant chemotherapy (CT) and hormonal therapy have not yet been established in these patients. Twenty-five PM-BC patients received, in sequence, leuprorelin, taxane-anthracycline induction chemotherapy, radiation therapy, a platinum-based intensification high-dose CT, followed by leuprorelin and anastrazole for five years. Vascular endothelial growth factor (VEGF) levels were measured as the primary end-point; secondary end-points were 10-year relapse-free survival (RFS) and overall survival (OS) rates. The median patient age was 44 years, and the mean number of positive axillary nodes was 14. All patients were ER(+) and/or PGR(+), with a median Ki-67 index of 33%. Five patients were Cerb-B2 positive. Grade 4 hematologic toxicity was observed in all patients, no patient showed a decrease of cardiac ejection fraction and hot flashes and arthralgias were of moderate intensity. After a median follow-up of 70 months, VEGF levels significantly decreased (p<0.001); 10-year RFS and OS were 76% and 78%, respectively. Total estrogen blockade and high-dose CT in PM-BC patients is feasible, has moderate toxicity, significantly reduces VEGF levels, and seems to improve the expected RFS and OS.

    Oncological treatment is currently directed toward a tailored therapy concept.Squamous cell carcinoma of the anal canal could be considered a suitable platform to test new therapeutic strategies to minimize treatment morbidity.Standard of care for patients with anal canal cancer consists of a combination of radiotherapy and chemotherapy.This treatment has led to a high rate of local control and a 60% cure rate with preservation of the anal sphincter,thus replacing surgical abdominoperineal resection.Lymph node metastases represent a critical independent prognostic factor for local recurrence and survival.Mesorectal and iliac lymph nodes are usually included in the radiation field,whereas the inclusion of inguinal regions still remains controversial because of the subsequent adverse side effects.Sentinel lymph node biopsies could clearly identify inguinal node-positive patients eligible for therapeutic groin irradiation.A sentinel lymph node navigation procedure is reported here to be a feasible and effective method for establishing the true inguinal node status in patients suffering from anal canal cancer.Based on the results of sentinel node biopsies,a selective approach could be proposed where node-positive patients could be selected for inguinal node irradiation while node-negative patients could take advantage of inguinal sparing irradiation,thus avoiding toxic side effects.

  2. Disorders of lymph flow.

    Witte, C L; Witte, M H

    1995-04-01

    Disturbances in blood capillary exchange of fluid, macromolecules, and cells across intact and abnormal microvessels and deranged lymphatic transport are integral, interacting components in disorders of tissue swelling. Lymphedema or low-output failure of the lymph circulation is often indolent for many years before lymphatic insufficiency (failure) and tissue swelling emerge and persist. Superimposed occult or overt infection (lymphangitis) are probably major contributors to progressive limb deformity (elephantiasis). Long-standing lymphedema is characterized by trapping in the skin and subcutaneous tissue of fluid, extravasated plasma proteins, and other macromolecules: impaired immune cell trafficking; abnormal processing of autologous and foreign antigens; heightened susceptibility to superimposed infection; local immunodysregulation; defective lymphatic (lymphangion) propulsion from an imbalance of mediators regulating vasomotion; soft-tissue overgrowth; scarring and hypertrophy; and exuberant angiogenesis occasionally culminating in vascular tumors (Fig. 8). In contrast to the blood circulation, where flow depends primarily on the propulsive force of the myocardium, lymph propulsion depends predominately on intrinsic truncal contraction, a phylogenetic vestige of amphibian lymph hearts. Whereas venous "plasma" flows rapidly (2-3 l/min) against low vascular resistance, lymph flows slowly (1-2 ml/min) against high vascular resistance. On occasion, impaired transport of intestinal lymph may be associated with reflux and accumulation and leakage of intestinal chyle in a swollen leg. Although the term "lymphedema" is usually reserved for extremity swelling, the pathogenesis of a wide variety of visceral disorders also may be traceable to defective tissue fluid and macromolecular circulation and impaired cell trafficking of lymphocytes and macrophages. Thus, lymph stasis, with impaired tissue fluid flow, underlies or complicates an indolent subclinical course with

    Objective To describe the endometrial pathologic lesions in premenopausal breast cancer patients with a history of tamoxifen (TMX) use. Methods We retrospectively reviewed the medical records of 120 premenopausal breast cancer patients with a history of TMX use that had undergone a gynecological examination. Results Among 120 patients, 44.2% (n=53) were asymptomatic with an endometrial thickness ≥5 mm, as assessed by transvaginal ultrasonography. Of the patients that reported abnormal uterine bleeding, 5% (n=6) had an endometrial thickness <5 mm and 20% (n=24) had an endometrial thickness ≥5 mm by transvaginal ultrasonography. The final group of patients were asymptomatic, but showed an abnormal endometrial lesion, such as an endometrial polyp, by transvaginal ultrasonography (30.8%, n=37). Of the 56 benign lesions that were histologically reviewed, 50 (41.7%) were endometrial polyps, 3 (2.5%) were submucosal myomas, 2 (1.7%) were endometrial hyperplasias, and 1 (0.8%) was chronic endometritis. There were 64 (53.3%) other non-pathologic conditions, including secreting, proliferative, and atrophic endometrium, or in some cases, there was insufficient material for diagnosis. In our data, only one case was reported as a complex hyperplasia without atypia arising from an endometrial polyp, and one patient was diagnosed with endometrioid adenocarcinoma. Conclusion For premenopausal breast cancer patients with a history of TMX use, the majority of the patients were asymptomatic, and endometrial polyps were the most common endometrial pathology observed. Therefore, we believe that endometrial assessment before starting TMX treatment, and regular endometrial screening throughout TMX treatment, are reasonable suggestions for premenopausal breast cancer patients.

    Acrylamide, a probable human carcinogen, is formed during high-temperature cooking of many commonly consumed foods. It is widespread; approximately 30% of calories consumed in the United States are from foods containing acrylamide. In animal studies, acrylamide causes mammary tumors, but it is unknown whether the level of acrylamide in foods affects human breast cancer risk. The authors studied the association between acrylamide intake and breast cancer risk among 90,628 premenopausal women in the Nurses' Health Study II. They calculated acrylamide intake from food frequency questionnaires in 1991, 1995, 1999, and 2003. From 1991 through 2005, they documented 1,179 cases of invasive breast cancer. They used Cox proportional hazards models to assess the association between acrylamide and breast cancer risk. The multivariable-adjusted relative risk of premenopausal breast cancer was 0.92 (95% confidence interval: 0.76, 1.11) for the highest versus the lowest quintile of acrylamide intake (Ptrend = 0.61). Results were similar regardless of smoking status or estrogen and progesterone receptor status of the tumors. The authors found no associations between intakes of foods high in acrylamide, including French fries, coffee, cereal, potato chips, potatoes, and baked goods, and breast cancer risk. They found no evidence that acrylamide intake, within the range of US diets, is associated with increased risk of premenopausal breast cancer. PMID:19224978

    We performed a meta-analysis to clarify whether the molecular detection of tumor cells or micrometastases in the lymph node (LN) indicates a high risk of disease recurrence and poor survival in negative pathologic lymph node status non-small cell lung cancer (NSCLC). A literature search was performed using relevant keywords. We searched relevant studies from PubMed, Embase, and the Cochrane Library. Direct and indirect meta-estimates were generated using Review Manager software with fixed effects for the study. Study-to-study heterogeneity was summarized using I (2) statistics and predictive intervals (PIs). Our analysis of eight eligible studies revealed that patients with lymph node micrometastases (LNMM) were associated with poor overall survival (OS) (HR, 1.98; 95 % CI, 1.50 to 2.62; p recurrence and poor survival in patients with negative pathologic node negative NSCLC. Thus, these patients need to be carefully followed up after the initial pulmonary resection.

    We performed a meta-analysis in order to determine whether the molecular tumour cell detection of either micrometastasis or isolated tumour cells in the bone marrow micrometastasis is indicative of a high risk of both disease recurrence and poor survival in the setting of node-negative non-small-cell lung cancer (NSCLC). Before beginning this study, a rigorous protocol was established in accordance with the recommendations of the Cochrane Collaboration. A systematic literature search of Medline, EMbase, the Cochrane Library and the Web of Science was conducted in order to identify studies regarding the prognostic value of molecular tumour cell detection in the bone marrow of node-negative NSCLC. Any study describing the use of both immunochemistry and flow cytometry to detect bone marrow metastasis was selected. We extracted the associated 95% confidence intervals (CIs) and hazard ratios (HRs) from the included studies and performed meta-analyses on overall survival and either disease-free survival (DFS) or disease-free recurrence. Meanwhile, we compared the occurrence of bone marrow micrometastasis among different pathological types and different stages of disease. Eleven studies with a cumulative sample size of 2159 patients were included in our analysis. Our meta-analyses revealed that the occurrence of bone marrow micrometastasis was not related to patient pathological types and stages in cancers ranging from adenocarcinoma and squamous cell carcinoma [relative risk (RR): 0.92; 95% CI: 0.78-1.08; P = 0.29], stages I and II (RR: 0.88; 95% CI: 0.67-1.17; P = 0. 39), stages II and III (RR: 0.98; 95% CI: 0.73-1.31; P = 0.89) and stages I and III (RR: 0.84; 95% CI: 0.68-1.05; P = 0.13). However, molecular tumour cell detection within the bone marrow was associated with both poor OS (HR: 1.84; 95% CI: 1.41-2.40; P recurrence in patients with node-negative NSCLC; this approach may result in the development of a new metastatic cascade concept and the development of

    AIM: To retrospectively evaluate the prevalence of lymph nodes of the hepato-duodenal ligament in a group of patients with chronic liver disease of various aetiologies and to investigate what clinical, aetiological and laboratory data may lead to their appearance. MATERIALS AND METHODS: One thousand and three patients (554 men, 449 women) were studied, including 557 with chronic hepatitis and 446 with liver cirrhosis. The presence of lymph nodes near the trunk of the portal vein, hepatic artery, celiac axis, superior mesenteric vein and pancreas head was investigated using ultrasound. RESULTS: Lymph nodes were detected in 394 out of the 1003 study patients (39.3%); their number ranged from one to four, with a diameter ranging between 0.8 and 4 cm. The highest prevalence was in the subgroup of patients with primary biliary cirrhosis (87.5%), followed by patients with hepatitis C virus (HCV; 42%), patients with HCV and hepatitis B virus (HBV; 41.3%), autoimmune hepatitis (40%), and HBV alone (21.2%). In the alcoholic and idiopathic subgroups prevalence was 9.5%, while in the non-alcoholic steatohepatitis and haemochromatosis subgroups it was 0%. HCV RNA was present in 97 out of 103 lymph node-positive patients and in 141 out of 168 lymph node-negative HCV-negative patients (p<0.003). Lymphadenopathy frequency increased as the liver disease worsened ({chi}{sup 2} MH=74.3; p<0.0001). CONCLUSION: Despite the limitations of a retrospective study, our data indicate a high prevalence of lymphadenopathy in liver disease patients; ultrasound evidence of lymph nodes of the hepato-duodenal ligament in a given liver disease may most likely suggest a HCV or an autoimmune aetiology and a more severe histological picture.

    BACKGROUND: In recent years, the technique of sentinel lymph node (SLN) mapping has been applied to colorectal cancer. One aim was to ultrastage patients who were deemed node negative by routine pathologic processing but who went on to develop systemic disease. Such a group may benefit from adjuvant chemotherapy. METHODS: With fully informed consent and ethical approval, 37 patients with primary colorectal cancer and 3 patients with large adenomas were prospectively mapped. Isosulfan blue dye (1 to 2 mL) was injected around tumors within 5 to 10 minutes of resection. After gentle massage to recreate in vivo lymph flow, specimens were placed directly into formalin. During routine pathologic analysis, all nodes were bivalved, and blue-staining nodes were noted. These later underwent multilevel step sectioning with hematoxylin and eosin and cytokeratin staining. RESULTS: SLNs were found in 39 of 40 patients (98% sensitivity), with an average of 4.1 SLNs per patient (range, 1-8). In 14 of 16 (88% specificity) patients with nodal metastases on routine reporting, SLN status was in accordance. Focused examination of SLNs identified occult tumor deposits in 6 (29%) of 21 node-negative patients. No metastatic cells were found in SLNs draining the three adenomas. CONCLUSIONS: The ability to identify SLNs after formalin fixation increases the ease and applicability of SLN mapping in colorectal cancer. Furthermore, the sensitivity and specificity of this simple ex vivo method for establishing regional lymph node status were directly comparable to those in previously published reports.

    Full Text Available Breast cancer is a significant health problem worldwide and is one of the leading causes of cancer-related mortality in women. Preoperative chemotherapy has become the standard of care for patients with locally advanced disease and is being used more frequently in patients with early-stage breast cancer. Sentinel lymph node biopsy has shown great promise in the surgical management of breast cancer patients, but its use following preoperative chemotherapy is yet to be determined. Eleven studies have been published with respect to the accuracy of sentinel lymph node biopsy following neoadjuvant chemotherapy. Ten studies showed favourable results, with the ability to identify a sentinel lymph node in 84% to 98% of cases, and reported false negative rates ranging from 0% to 20%. The accuracy of sentinel lymph node biopsy following preoperative chemotherapy for breast cancer ranges from 88% to 100%, with higher rates when specific techniques and inclusion criteria are applied. The published literature supports the use of sentinel lymph node biopsy for assessment of the axilla in patients with clinically node-negative disease following preoperative chemotherapy.

    We evaluated urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) prognostic value in postmenopausal, node-negative breast cancer patients bearing tumors with estrogen receptor (ER)/progesterone receptor (PR) expression, treated with locoregional therapy alone, within an early follow-up. We focused our analysis on tumors of histological grade II in order to improve its prognostic value and, consequently, to improve a decision-making process. The cytosol extracts of 73 tumor samples were used for assessing several biomarkers. ER and PR levels were measured by classical biochemical method. Cathepsin D was assayed by a radiometric immunoassay while both uPA and PAI-1 level determinations were performed by enzyme-linked immunosorbent assays. HER-2 gene amplification was determined by chromogenic in situ hybridization (CISH) in primary tumor tissue. Patients bearing tumors smaller than or equal to 2 cm (pT1) or those with low PAI-1 levels (PAI-1 PAI-1 levels, respectively. Analyses of 4 phenotypes, defined by tumor size and PAI-1 status, revealed that patients bearing either pT1 tumors, irrespective of PAI-1 levels, or pT2,3 tumors with low PAI-1 levels, had similar disease-free interval probabilities and showed favorable outcome compared to those bearing pT2,3 tumors with high PAI-1 levels. Our findings suggest that tumor size and PAI-1, used in combination as phenotypes are not only prognostic but might also be predictive in node-negative, postmenopausal breast cancer patients bearing histological grade II tumors with ER/PR expression, during an early follow-up period.

    The Cell Cycle Profiling - Risk Score (C2P-RS) based on CDK1 and CDK2 specific activities was significantly associated with relapse in breast cancers. We evaluated the prognostic value of the C2P-RS classification using a Japanese cohort including node-negative, hormone receptor-positive breast cancers treated with adjuvant endocrine therapy alone as systemic therapy. Of 266 patients, 22 (8.3%) relapsed within 5 years after surgery. The distribution of each C2P-RS group was 71.8% in the low group, 12.0% in the intermediate group, and 16.2% in the high group. The 5-year relapse-free survival rate in the low C2P-RS group (97.3%) was significantly higher than that in the intermediate C2P-RS group (84.3%) or the high C2P-RS group (74.4%) (P < 0.001). The univariate analysis demonstrated that age, tumor size, histologic grade, and HER2 had no significant correlations with relapse but the C2P-RS classification (P < 0.001) and Ki-67 (P = 0.009) were significantly associated with relapse. Multivariate analysis showed only that the C2P-RS classification was a significant independent prognostic indicator. The C2P-RS classification might be a significant predictor of earlier recurrence in node-negative, hormone receptor-positive breast cancers treated with endocrine therapy.

    Post-exercise heart rate recovery (HRR) has been proposed as a measure of cardiac autonomic dysfunction in apparently healthy adults. We aimed to determine the effects of a lifestyle intervention on HRR among clinically obese premenopausal women. A randomized controlled trial was conducted to investigate the effects of a 3-month non-dieting lifestyle intervention program on cardiorespiratory fitness (CRF) and HRR among healthy clinically obese premenopausal women. Thirty-one were randomly assigned to 3-month intensive lifestyle intervention and 31 served as controls. Sixty-one participants performed a maximal treadmill walking test with metabolic gas exchange. Baseline anthropometric measures were closely related to HRR at 1 min, which may indicate reduced parasympathetic reactivation. Post-exercise HRR at 60 s (HRR60) increased from 21.3 ± 6.2 to 27.8 ± 10.2 bpm in the intervention group compared with a smaller reduction (26.8 ± 12.3 to 24.5 ± 9.9 bpm) in controls (test for interaction P = 0.0001). HRR120 showed a significant effect of time (P = 0.0002) with no significant interaction with lifestyle intervention. A significant increase in VO2 peak was evident in the lifestyle group (21.6 to 23.6 mL/kg/min) compared with a modest reduction in the controls (22.6 to 21.6 mL/kg/min; test for interaction, P = 0.001). Clinically obese healthy premenopausal women achieved significant improvements in HRR60 and VO peak following a 3-month intensive lifestyle intervention. © 2012 John Wiley & Sons A/S.

  13. Lymphangiogenesis and lymph node metastasis in breast cancer

    2008-03-01

    Full Text Available Abstract Introduction There have been few studies on lymphangiogenesis in the past due to the lack of specific lymphatic endothelial markers, and lymphatic-specific growth factors. Recently, these limitations have been relieved by the discovery of a small number of potential lymphatic-specific markers. The relationship between lymphangiogenesis and regional or distant metastasis has not previously been investigated in humans. Using these lymphatic markers, it is possible to explore the relationship between lymphangiogenesis and tumour metastasis. This study indirectly quantified lymphangiogenesis by measuring mRNA expression of all seven lymphatic markers described above in breast cancers and correlated these markers with lymphatic involvement and survival. The cDNA from 153 frozen archived breast samples were analysed with Q-PCR for all seven lymphangiogenic markers. This was correlated with various prognostic factors as well as patient survival. Results There was significantly greater expression of all 7 markers in malignant compared to benign breast tissue. In addition, there was greater expression in lymph node positive/grade 3 tumours when compared to lymph node negative/grade 1 tumours. In 5 of the markers, there was a greater expression in poor NPI prognostic tumours when compared to favourable prognostic tumours which was not statistically significant. There was no association between recurrence risk and lymphangiogenic marker expression. Conclusion In summary, the findings from this study show that lymphangiogenesis, measured by specific lymphatic marker expression, is higher in breast cancers than in normal breast tissue. Secondly, breast cancers which have metastasised to the regional lymphatics show higher expression compared to those which have not, although the individual differences for all five markers were not statistically significant.

    Sentinel lymph node biopsy (SLNB), a less invasive alternative to axillary lymph node dissection (ALND), has become the standard of care for patients with clinically node-negative breast cancer. In SLNB, lymphatic mapping with radio-labeled sulfur colloid and/or blue dye helps identify the sentinel lymph node (SLN), which is most likely to contain metastatic breast cancer. Even though SLNB, using both methylene blue and radioactive tracers, has a high identification rate, it still relies on an invasive surgical procedure, with associated morbidity. In this study, we have demonstrated a non-invasive single-walled carbon nanotube (SWNT)-enhanced photoacoustic (PA) identification of SLN in a rat model. We have successfully imaged the SLN in vivo by PA imaging (793 nm laser source, 5 MHz ultrasonic detector) with high contrast-to-noise ratio (=89) and good resolution (~500 µm). The SWNTs also show a wideband optical absorption, generating PA signals over an excitation wavelength range of 740-820 nm. Thus, by varying the incident light wavelength to the near infrared region, where biological tissues (hemoglobin, tissue pigments, lipids and water) show low light absorption, the imaging depth is maximized. In the future, functionalization of the SWNTs with targeting groups should allow the molecular imaging of breast cancer.

    Two cases of group A streptococcus (GAS) causing vulvovaginitis in premenopausal adults are described. A review of the literature of genital GAS is made, as this is an uncommon cause of vulvovaginitis in premenopausal adults. Contrasts are made between anogenital carriage of GAS and group B streptococcus (GBS) to highlight the differences in anogenital carriage between these two organisms.

    The staging of node-negative non-small-cell lung cancer is modified in the 7th edition TNM classification. Here, we pool data from the National Cancer Institute of Canada Clinical Trials Group JBR.10 trial and the Cancer and Leukemia Group B-9633 trial to explore the prognostic and predictive effects of the new T-size descriptors and KRAS mutation status. Node-negative patients were reclassified as T2a (>3-≤5 cm), T2b (>5-≤7 cm), T3 (>7 cm) or T ≤ 3 cm (≤3 cm, but other T2 characteristics). Of 538 eligible patients, 288 (53.5%) were T2a, 111 (21%) T2b, 62 (11.5%) T3, whereas 77 (14%) T≤3 cm were excluded to avoid confounding. KRAS mutations were detected in 104 of 390 patients (27%). T-size was prognostic for disease-free survival (p = 0.03), but borderline for overall survival (OS; p = 0.10), on multivariable analysis. Significant interaction between the prognostic value of KRAS and tumor size was observed for OS (p = 0.01), but not disease-free survival (p = 0.10). There was a nonsignificant trend (p = 0.24) for increased chemotherapy effect on OS with advancing T-size (hazard ratio [HR] T2a 0.90, [0.63-1.30]; T2b 0.69, [0.38-1.24]; and T3 0.57, [0.28-1.17]). The HR for chemotherapy effect on OS in T2a patients with KRAS wild-type tumors was 0.81 (p = 0.36), whereas a trend for detrimental effect was observed in those with mutant tumors (HR 2.11; p = 0.09; interaction p = 0.05). Similar trends were observed in T2b to T3 patients with wild-type (HR 0.86; p = 0.62), and KRAS mutant tumors (HR 1.16; p = 0.74; interaction p = 0.58). Chemotherapy effect seems to increase with tumor size. However, this small study could not identify subgroups of patients who did or did not derive significant benefit from adjuvant chemotherapy based on T-size or KRAS status.

    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.

    No evidence exists to recommend a specific chemotherapy regimen in young breast cancer patients. We performed a pooled analysis of two randomised clinical trials to evaluate the efficacy of adjuvant dose-dense chemotherapy in premenopausal breast cancer patients and its impact on the risk of treatment-induced amenorrhoea. In the MIG1 study, node-positive or high-risk node-negative patients were randomised to 6 cycles of fluorouracil/epirubicin/cyclophosphamide every 2 (dose-dense) or 3 (standard-interval) weeks. In the GIM2 study, node-positive patients were randomised to 4 cycles of dose-dense or standard-interval EC or FEC followed by 4 cycles of dose-dense or standard-interval paclitaxel. Using individual patient data, the hazard ratio (HR) for overall survival by means of a Cox proportional hazards model and the odds ratio for treatment-induced amenorrhoea through a logistic regression model were calculated for each study. A meta-analysis of the two studies was performed using the random effect model to compute the parameter estimates. A total of 1,549 patients were included. Dose-dense chemotherapy was associated with a significant improved overall survival as compared to standard-interval chemotherapy (HR, 0.71; 95% confidence intervals [CI], 0.54-0.95; p = 0.021). The pooled HRs were 0.78 (95% CI, 0.54-1.12) and 0.65 (95% CI, 0.40-1.06) for patients with hormone receptor-positive and -negative tumours, respectively (interaction p = 0.330). No increased risk of treatment-induced amenorrhoea was observed with dose-dense chemotherapy (odds ratio, 1.00; 95% CI, 0.80-1.25; p = 0.989). Dose-dense adjuvant chemotherapy may be considered the preferred treatment option in high-risk premenopausal breast cancer patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The clinical characteristics was studied on 431 women with uterine bleedings during the premenopaussal phase of the climacterium. The author established that menarche, duration of menstrual interval and the menstruation itself before the bleeding did not differ from those of female population in the country. The same was referred to the reproductive characteristics. Premenopausal bleeding reached its peak between 46 and 48 years of age as its duration was relatively great. It was connected with frequent neuro-endocrine and metabolic pathology. The most frequent manifestations were obesity and hypertension. The number of the former hepatitis patients was comparatively large. Diseases of the uterine body were frequent in the structure of genital pathology. The frequency of benign, precancerous and malignant neoplastic processes (without myoma) was high-12.7%.

    Single-hormone prophylaxis with gestagen (Primolut nor) was carried out on 62 women with uterine bleedings during the premenopause of climacteric at mean age of 46.8 years. A ten-day scheme with application of 5 mg of gestagen daily from 16 to 25 day of the cycle for a period of 6 months was used. The treatment provided stable clinical characteristic of the successive pseudomenstrual cycles could continue for a considerable time practically till disappearance of pseudo-menstruation and transition of the woman in postmenopause. Primolut nor was a convenient drug also in women under continuous anticoagulant treatment. However it was effective and could not be used for treatment of accompanied climacteric symptoms.

    Mammographic density (MD), a strong marker of breast cancer risk, is influenced by genetic, environmental, and hormonal factors. Cadmium, a persistent and widespread environmental pollutant, has been associated with risk of breast cancer, and laboratory evidence suggests cadmium is a carcinogen in the breast. We investigated the hypothesis that cadmium exposure is associated with higher MD. In a cross-sectional study of MD and urinary cadmium concentration, percentage MD (MD%) and Breast Imaging-Reporting and Data Systems (BI-RADS®) density category were determined from screening mammograms of 190 premenopausal women ages 40-45 years. Women completed a health questionnaire, and the cadmium content of spot urine samples was measured with inductively coupled plasma mass spectrometry and corrected for urine creatinine. Urinary cadmium concentrations are thought to reflect exposure to cadmium during a period of 20-30 years. Multivariable linear regression and logistic regression were used to estimate the strength of association between urinary cadmium and mammographic breast density. Adjusted mean MD% among women in the upper tertile of creatinine-corrected urinary cadmium was 4.6% higher (95% CI: -2.3 to 11.6%) than in women in the lowest cadmium tertile. Each twofold increase in urinary cadmium was associated with higher odds of MD% in the upper tertile (OR: 1.29, 95% CI: 0.82-2.02) or a BI-RADS category rating of "extremely dense" (OR: 1.75, 95% CI: 1.14-2.70). Stronger associations were observed among nulliparous women, and current or former smokers. Exposure to cadmium may be associated with increased breast density in premenopausal women.

  4. Role of Ovarian Function Suppression in Premenopausal Women with Early Breast Cancer

    Science.gov (United States)

    2016-01-01

    Historically, endocrine therapy for breast cancer began with ovarian ablation (OA) for the treatment of premenopausal patients. After the identification of estrogen receptors and the development of many antiestrogens, tamoxifen has been approved and used as the standard endocrine therapy for hormonal receptor (HR)-positive premenopausal patients to date. With the development of luteinizing hormone-releasing hormone agonists, the paradigm of endocrine therapy for premenopausal women with HR-positive breast cancer began to change from OA to ovarian function suppression (OFS). To date, the indication for OFS was limited to those premenopausal patients with HR-positive breast cancer who were unable to use tamoxifen as the primary adjuvant endocrine therapy. However, following the definitive demonstration of the therapeutic role of OFS added to tamoxifen or aromatase inhibitor after chemotherapy in large randomized trials, such as Tamoxifen and Exemestane Trial or Suppression of Ovarian Function Trial, the American Society of Clinical Oncology guidelines for the use of endocrine therapy in premenopausal HR-positive breast cancer were recently updated to recommend OFS in high-risk patients who required adjuvant chemotherapy. In contrast, the role of OFS to protect ovarian function during chemotherapy in premenopausal women has remained controversial, and some evidence showing the protective effect of OFS on the ovaries during chemotherapy as well as its therapeutic effect for breast cancer in premenopausal women with HR-negative breast cancer was recently published. Further evaluation is necessary to determine its exact role. In conclusion, the role of OA or OFS has been evolving, not only to improve the efficacy of breast cancer treatment, but also to preserve ovary function. OFS remains a main strategy for premenopausal women with HR-positive early breast cancer, though its exact role should be determined in further studies. PMID:28053622

    Background: Cadmium, a persistent and widespread environmental pollutant, has been associated with kidney function impairment and several diseases. Cigarettes are the dominant source of cadmium exposure among smokers; the primary source of cadmium in non-smokers is food. We investigated sources of cadmium exposure in a sample of healthy women. Methods: In a cross-sectional study, 191 premenopausal women completed a health questionnaire and a food frequency questionnaire. The cadmium content of spot urine samples was measured with inductively-coupled plasma mass spectrometry and normalized to urine creatinine content. Multivariable linear regression was used to estimate the strength of association between smoking habits and, among non-smokers, usual foods consumed and urinary cadmium, adjusted for age, race, multivitamin and supplement use, education, estimated total energy intake, and parity. Results: Geometric mean urine creatinine-normalized cadmium concentration (uCd) of women with any history of cigarette smoking was 0.43 {mu}g/g (95% confidence interval (CI): 0.38-0.48 {mu}g/g) and 0.30 {mu}g/g (0.27-0.33 {mu}g/g) among never-smokers, and increased with pack-years of smoking. Analysis of dietary data among women with no reported history of smoking suggested that regular consumption of eggs, hot cereals, organ meats, tofu, vegetable soups, leafy greens, green salad, and yams was associated with uCd. Consumption of tofu products showed the most robust association with uCd; each weekly serving of tofu was associated with a 22% (95% CI: 11-33%) increase in uCd. Thus, uCd was estimated to be 0.11 {mu}g/g (95% CI: 0.06-0.15 {mu}g/g) higher among women who consumed any tofu than among those who consumed none. Conclusions: Cigarette smoking is likely the most important source of cadmium exposure among smokers. Among non-smokers, consumption of specific foods, notably tofu, is associated with increased urine cadmium concentration. - Research highlights: {yields

  8. Management of the Hepatic Lymph Nodes during Resection of Liver Metastases from Colorectal Cancer: A Systematic Review

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Background. Hepatic lymph node involvement is generally considered a contraindication for liver resection performed for colorectal liver metastases. However, some advocate hepatic lymphadenectomy in the presence of macroscopic involvement and others routine lymphadenectomy. The aim of this review is to assess the role of lymphadenectomy in resection of liver metastases from colorectal cancer. Methods. Medline, Embase and Central databases were searched using a formal search strategy. Trials with survival data with a minimum follow-up of 1 year were considered for inclusion. Meta-analysis was performed using Revman. Results. A total of 4230 references were identified. Ten reports of nine studies including 926 patients qualified for the review. The prevalence of nodal metastases after routine lymphadenectomy was 16.3%. The overall 3-year and 5-year survival rates in node-positive patients were 9/151 (11.3% and 2/137 (1.5%, respectively, compared to 3-year and 5-year survival rates of 424/787 (53.9% and 246/767 (32.1% in node-negative patients. The odds ratios for 3-year and 5-year survivals in node positive disease compared to node-negative disease were 0.12 (95% CI 0.06 to 0.24 and 0.08 (95% CI 0.03 to 0.22. There was no randomized controlled trial which assessed the survival benefit of routine or “selective” lymphadenectomy. Conclusion. Currently, there is no evidence of survival benefit for routine or selective lymphadenectomy. Survival rates are low in patients with positive lymph nodes draining the liver irrespective of whether they are detected by routine lymphadenectomy or by macroscopic involvement. Further trials in this patient group are required.

    The fibromyalgia syndrome (FMS) is a chronic, widespread pain disorder of unknown etiology. It has been suggest that familial component, environmental factors, endocrine and neurotransmitter alterations, and psychological factors may contribute to the development of FMS. The role of melatonin in FMS is unclear. Some studies describe a lower nocturnal peak and a decreased secretion of melatonin in women with FMS when compared with healthy matched controls. The aim of the present study was to determine the possible role of melatonin in FMS patients. We examined the characteristics and levels of melatonin in 25 consecutive premenopausal women with FMS. Serum blood samples were collected from 25 patients and 20 the age and gender matched healthy controls. Melatonin levels were measured by enzyme-linked immunosorbent assay. Then, the results were compared with those from healthy subjects. Serum melatonin levels of FMS patients were not statistically different from those of controls (P > 0.05). No association was observed between melatonin levels of patients with FMS and disease duration, sleep disturbances, fatigue, and pain scores. Our results demonstrate that melatonin levels were similar in patients with FMS and healthy controls. Further studies are needed to determine the possible role of melatonin.

    Full Text Available Background This article presents the results of studying the specific features (rat, pig, sheep, cow of spontaneous rhythmic contractile activity of the lymph nodes of internal organs and body, the role of intranode pressure in the genesis of a node reduction of the lymph nodes activity regulation under the influence of biologically active substances, and the drug immunal and feed additives – polfamix on spontaneous contractile activity of a lymphatic node. Aims So far, well researched are the thin structural-topographic formation and innervation of the lymph circulation machine, the main functions (drainage, immunological, protein transport, etc. of the lymphatic system are set, which ensure the preservation of endoecological homeostasis of the organism environments. Methods We used the technique of recording contractions of isolated solitary lymph nodes of the body and internal organs, placed in an oxygenized chamber with Krebs medium. Results We found a direct link between the spontaneous rhythmic contractile activity of a lymph node and its internal pressure. A direct relationship is established: the higher within certain limits micronodular pressure is, the more intense is the reduction node (r+0,879. Conclusion As well as giving data from the manuscript there will be presentation of the main points of lymph node’s values in the organism.

    To identify factors that influence the total and negative lymph node counts in colorectal cancer resection specimens independent of pathologists and surgeons. We used multivariate negative binomial regression. Covariates included age, sex, body mass index, family history of colorectal carcinoma, year of diagnosis, hospital setting, tumor location, resected colorectal length (specimen length), tumor size, circumferential growth, TNM stage, lymphocytic reactions and other pathological features, and tumor molecular features (microsatellite instability, CpG island methylator phenotype, long interspersed nucleotide element 1 [LINE-1] methylation, and BRAF, KRAS, and PIK3CA mutations). Two US nationwide prospective cohort studies. Patients with rectal and colon cancer (N=918). The negative and total node counts (continuous). Specimen length, tumor size, ascending colon location, T3N0M0 stage, and year of diagnosis were positively associated with the negative node count (all P.002). Mutation of KRAS might also be positively associated with the negative node count (P=.03; borderline significance considering multiple hypothesis testing). Among node-negative (stages I and II) cases, specimen length, tumor size, and ascending colon location remained significantly associated with the node count (all P.002), and PIK3CA and KRAS mutations might also be positively associated (P=.03 and P=.049, respectively, with borderline significance). This molecular pathological epidemiology study shows that specimen length, tumor size, tumor location, TNM stage, and year of diagnosis are operator-independent predictors of the lymph node count. These crucial variables should be examined in any future evaluation of the adequacy of lymph node harvest and nodal staging when devising individualized treatment plans for patients with colorectal cancer.

    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.

    Physical activity has been associated with decreased breast cancer risk, potentially through changes in estrogen metabolism. Two-hydroxyestrone (2-OHE1) and 16alpha-hydroxyestrone (16alpha-OHE1) have different biological properties, and the ratio of these metabolites (2/16) has been proposed to predict breast cancer risk. Diet and exercise have been found to influence estrogen metabolism, particularly when a state of negative energy balance is achieved. We sought to determine whether 4 months of moderate-intensity exercise coupled with calorie restriction would result in changes in urinary 2-OHE1, 16alpha-OHE1, or 2/16 in sedentary, premenopausal, eumenorrheic women. Average age was 31.5 yr, average body fat was 31.6%, and average BMI was 23.7. Urinary estrogen metabolites were measured in 24 women during the baseline and for four intervention months in the midfollicular and midluteal phases. The intervention produced a significant drop in body fat (4.5%) and body weight (3.7 kg). Aerobic fitness increased significantly (26%; P effects of the diet and exercise intervention on 2-OHE1, 16alpha-OHE1, or 2/16. However, when divided into tertiles according to baseline 2/16, the intervention resulted in significant increases in 2/16 in women in the lowest tertile. Women in the lowest tertile (average 2/16 = 0.91) did not differ from the other tertiles in baseline estradiol concentrations, body fat, weight, fitness, or changes in these variables with the intervention. The data suggest that women at higher risk for developing breast cancer because of low 2/16 may reduce their risk by participating in lifestyle interventions such as exercise/calorie restriction.

    Osteoporosis and sarcopenia are common health problems in postmenopausal women. However, studies of these issues in premenopausal women are limited. Our present study aimed to investigate relationship the between underweight, bone mineral density (BMD) and skeletal muscle index (SMI) in a representative sample of premenopausal Korean women. We used data from the Korea National Health and Nutrition Examination Surveys (2009-2010). Participants included 1767 healthy, ≥ 20-year-old, non-obese premenopausal women. Underweight was defined as BMIrelationship between underweight, BMD and SMI after adjusting for confounding factors. The prevalence of low BMD and low SMI in underweight women was 23.9% and 18.4%, respectively, compared with 9.4% and 1.7% in normal weight women. Low BMD and/or low SMI were present in 36.7% of underweight women compared with 10.7% of normal weight women. After adjustments, underweight women exhibited a higher odds ratio for low BMD (OR, 3.41; 95% CI, 2.31-5.05), low SMI (OR, 11.61; 95% CI, 6.17-21.88) and combined low BMD and low SMI (OR, 23.82; 95% CI, 8.92-63.58) when compared with normal weight women. Underweight premenopausal women are at a higher risk of low bone mass and low skeletal muscle. Educational efforts that promote a normal weight in premenopausal women should be reinforced. © 2016 John Wiley & Sons Ltd.

    Bone loss prior to menopause may contribute to later risk of fracture due to osteoporosis. Women may be able to optimize premenopausal bone mass and/or prevent losses. Heredity, and possibly age at menarche (retrospectively determined), are unmodifiable risk factors and attention should therefore be directed to more amenable factors. Amenorrhea, low body weight, disordered eating, and smoking are modifiable risk factors. Vitamin D is not a factor for premenopausal women who receive incidental sun exposure and consume fortified foods, but supplementation should be considered for others, especially during the winter months. Protective factors include a higher body weight (especially due to increased muscularity), calcium supplementation, and purposeful load-bearing exercise. Positive effects of oral contraceptives are most apparent in women with menstrual irregularities. Reproductive history (parity), lactation, moderate intakes of alcohol and caffeine, and the appropriate treatment of endometriosis have no apparent effect on premenopausal bone.

    A growing number of premenopausal women are currently using antithrombotic and/or (dual) antiplatelet therapy for various cardiovascular indications. These may induce or exacerbate abnormal uterine bleeding and more awareness and knowledge among prescribers is required. Heavy and irregular menstrual bleeding is common in women in their forties and may have a variety of underlying causes that require different treatment options. Thus using anticoagulants in premenopausal women demands specific expertise and close collaboration between cardiovascular physicians and gynecologists. In this article we summarize the scope of the problem and provide practical recommendations for the care for young women taking anticoagulants and/or (dual) antiplatelet therapy. We also recommend that more safety data on uterine bleeding with novel anticoagulants in premenopausal women should be obtained.

    @@ Pre-menopausal women are at risk for iron deficiency due to menstrual blood losses. The prevalence rates (PR) of iron depletion, iron deficiency anemia (IDA), and iron deficiency were 34.4%, 15.1% and 49.5% in pre-menopausal non-pregnant women respectively in China.1 Traditionally, the diagnosis of iron deficiency relies on the hematological markers (hemoglobin (HGB),mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), red cell distribution width (RDW))and biochemical markers (serum ferritin (SF), serum iron (SI), transferrin saturation (TS), total iron-binding capacity (TIBC)). Recently, the reticulocyte hemoglobin content (CHr) is considered to be used as a marker of iron deficiency.2 The aim of this study was to compare the diagnostic efficiency of CHr with the old markers in diagnosis of iron deficiency in Chinese pre-menopausal women.

    Full Text Available Beverly G Reed, Laurice Bou Nemer, Bruce R Carr Department of Obstetrics and Gynecology, Division of Reproductive Endocrinology & Infertility, University of Texas Southwestern Medical Center, Dallas, TX, USA Background: There are limited evaluation and treatment options for low libido in premenopausal women. This review sought to evaluate the available evidence supporting the evaluation of testosterone serum levels and testosterone treatment of premenopausal women with low libido. Methods: MEDLINE, PubMed, and ClinicalTrials.gov were searched for articles that referenced the evaluation of testosterone serum level and/or testosterone treatment on premenopausal women with low libido from 1995 to 2015. Additional references were obtained from the reference sections of other papers and from peer review. Studies that included only postmenopausal women were excluded. A total of 13 studies were reviewed in detail. Nine studies examined the relationship between testosterone serum levels and sexuality, an additional three studies examined the effect of testosterone treatment on premenopausal women with low libido, and one study examined both the topics. Results: Six of the ten testosterone serum evaluation studies failed to show a significant association between testosterone serum level and libido. Only one out of four studies examining testosterone treatment in premenopausal women was able to show any clear improvement in libido; however, the effect was limited to only the intermediate dose of testosterone, with the low and high doses of testosterone not producing any effect. Conclusion: The currently available evidence does not support testosterone serum evaluation or treatment in premenopausal women with low libido. Hence, further studies are warranted.

    The aim of the study is to compare levels of depression-anxiety and disability in premenopausal and postmenopausal women. The study was carried out with women between 45-55 years of age, living in the service area of a Mother-Child Health and Family Planning Center. Women who did not have a menstruation at least for one year were accepted as postmenopausal. The premenopausal group was consisted of women having menstruation. Hospital Anxiety and Depression Scale (HAD) and Brief Disability Questionnaire (BDQ) were applied to the women. Four hundred and ninety four women were recruited to the study. There were 214 women in the premenopausal period and 280 women in the postmenopausal period. In premenopausal women the level of education was higher and smoking was more prevalent; whereas in postmenopausal women the prevalence rates of being housewife and having continuous drug therapy due to chronic physical diseases were higher. In postmenopausal women, levels of depression and disability were significantly higher. In this group, the predictive factors for having a high HAD score were disability, education having a previous psychiatric disorder having drug therapy due to chronic physical diseases, diabetes mellitus, low level, menopause before the age of 40, not having any counselling for menopause, and not having routine laboratory tests. Having a previous psychiatric disorder and not having any counselling were also predicting disability. None of the variables predicted a high HAD score psychiatric disorder and not having any counselling were also predicting disability and disability in the premenopausal women. The postmenopausal period seems to predispose women to depressive symptoms and disability compared to the premenopausal period.

    Suppressing sex hormones in women for 1 wk reduces resting energy expenditure (REE). The effects of more chronic suppression on REE and other components of total energy expenditure (TEE), and whether the reduction in REE is specifically due to loss of estradiol (E2), are not known. We compared the effects of 5 mo of sex hormone suppression (gonadotropin releasing hormone agonist therapy, GnRHAG) with placebo (PL) or E2 add-back therapy on REE and the components of TEE. Premenopausal women received GnRHAG (leuprolide acetate 3.75 mg/mo) and were randomized to receive transdermal therapy that was either E2 (0.075 mg/d; n = 24; means ± SD, aged = 37 ± 8 yr, BMI = 27.3 ± 6.2 kg/m(2)) or placebo (n = 21; aged = 34 ± 9 yr, BMI = 26.8 ± 6.2 kg/m(2)). REE was measured by using a metabolic cart, and TEE, sleep EE (SEE), exercise EE (ExEE, 2 × 30 min bench stepping), non-Ex EE (NExEE), and the thermic effect of feeding (TEF) were measured by using whole room indirect calorimetry. REE decreased in GnRHAG+PL [mean (95% CI), -54 (-98, -15) kcal/d], but not GnRHAG+E2 [+6 (-33, +45) kcal/d] (difference in between-group changes, P < 0.05). TEE decreased in GnRHAG+PL [-128 (-214, -41) kcal/d] and GnRHAG+E2 [-96 (-159, -32) kcal/d], with no significant difference in between-group changes (P = 0.55). SEE decreased similarly in both GnRHAG+PL [-0.07 (-0.12, -0.03) kcal/min] and GnRHAG+E2 [-0.07 (-0.12, -0.02) kcal/min]. ExEE decreased in GnRHAG+PL [-0.46 (-0.79, -0.13) kcal/min], but not GnRHAG+E2 [-0.30 (-0.65, +0.06) kcal/min]. There were no changes in TEF or NExEE in either group. In summary, chronic pharmacologic suppression of sex hormones reduced REE and this was prevented by E2 therapy.

    The aim of this study was to evaluate the prognostic potential of quantitative reverse-transcription, polymerase chain reaction (qRT-PCR) in melanoma patients with pathologically negative sentinel lymph nodes (SLN). Our study included 195 node-negative melanoma patients with a Breslow thickness greater than 0.76 mm (n = 158), or less than 0.76 mm but who had Clark level IV-V, microscopic ulceration, or pathological signs of regression (n = 32), and five patients with melanoma of unknown thickness. SLNs were examined by serial-section histopathology. A portion of each SLN was frozen for qRT-PCR analysis using markers Tyrosinase, MART1, SSX2, MAGEA3, PAX3, and GalNAc-T. In addition, two other markers (PLAB and L1CAM) were evaluated for melanoma specificity but not for SLN analysis. Median follow-up was 64 months, during which time there were 15 (7.7%) recurrences. A total of 370 lymph nodes were analyzed by qRT-PCR. No association was found between quantitative expression level of any marker and disease recurrence. Previously published primer designs were tested for PAX3 and GalNAc-T and revealed that alternative PAX3 transcripts are differentially expressed in melanoma and benign lymph nodes. No associations with recurrence were found regardless of the transcripts amplified by different primer sets. PLAB and L1CAM did not appear to differentiate between malignant melanoma and benign melanocytes or lymph nodes in our analysis. We conclude that, in this large cohort of patients, multimarker qRT-PCR analysis of SLNs did not correlate with disease recurrence. Our data support specific PAX3 splice variants but not GalNAc-T, PLAB or L1CAM as possible markers for melanoma metastasis to SLNs.

    Full Text Available BACKGROUND: We previously reported the utility of preoperative nuclear morphometry for evaluating risk for cervical lymph node metastases in tongue squamous cell carcinoma. The risk for lymph node metastasis in oral squamous cell carcinoma, however, is known to differ depending on the anatomical site of the primary tumor, such as the tongue, gingiva, mouth floor, and buccal mucosa. In this study, we evaluated the applicability of this morphometric technique to evaluating the risk for cervical lymph node metastasis in oral squamous cell carcinoma. METHODS: A digital image system was used to measure the mean nuclear area, mean nuclear perimeter, nuclear circular rate, ratio of nuclear length to width (aspect ratio, and nuclear area coefficient of variation (NACV. Relationships between these parameters and nodal status were evaluated by t-test and logistic regression analysis. RESULTS: Eighty-eight cases of squamous cell carcinoma (52 of the tongue, 25 of the gingiva, 4 of the buccal mucosa, and 7 of the mouth floor were included: 46 with positive node classification and 42 with negative node classification. Nuclear area and perimeter were significantly larger in node-positive cases than in node-negative cases; however, there were no significant differences in circular rate, aspect ratio, or NACV. We derived two risk models based on the results of multivariate analysis: Model 1, which identified age and mean nuclear area and Model 2, which identified age and mean nuclear perimeter. It should be noted that primary tumor site was not associated the pN-positive status. There were no significant differences in pathological nodal status by aspect ratio, NACV, or primary tumor site. CONCLUSION: Our method of preoperative nuclear morphometry may contribute valuable information to evaluations of the risk for lymph node metastasis in oral squamous cell carcinoma.

    Abstract Background: The lymphatic system is commonly injured during cancer treatment. However, despite the morbidity of these injuries, there are currently no options for replacing damaged lymphatics. The purpose of this study was to optimize methods for decellularization of murine lymph nodes (LN) and to determine if these scaffolds can be used to tissue engineer lymph node-like structures. Methods and Results: LNs were harvested from adult mice and subjected to various decellularization protocols. The degree of decellularization and removal of nuclear material was analyzed histologically and quantitatively using DNA isolation. In addition, we analyzed histological architecture by staining for matrix proteins. After the optimal method of decellularization was identified, decellularized constructs were implanted in the renal capsule of syngeneic or allogeneic recipient mice and analyzed for antigenicity. Finally, to determine if decellularized constructs could deliver lymphocytes to recipient animals, the matrices were repopulated with splenocytes, implanted in submuscular pockets, and harvested 14 days later. Decellularization was best accomplished with the detergent sodium dodecyl sulfate (SDS), resulting in negligible residual cellular material but maintenance of LN architecture. Implantation of decellularized LNs into syngeneic or allogeneic mice did not elicit a significant antigenic response. In addition, repopulation of decellularized LNs with splenocytes resulted in successful in vivo cellular delivery. Conclusions: We show, for the first time, that LNs can be successfully decellularized and that these matrices have preserved extracellular matrix architecture and the potential to deliver leukocytes in vivo. Future studies are needed to determine if tissue engineered lymph nodes maintain immunologic function. PMID:25144673

    Nodal staging is important in prostate cancer treatment. While surgical lymph node dissection is the classic method of determining whether lymph nodes harbor malignancy, this is a very invasive technique. Current noninvasive approaches to identifying malignant lymph nodes are limited. Conventional imaging methods rely on size and morphology of lymph nodes and have notoriously low sensitivity for detecting malignant nodes. New imaging techniques such as targeted positron emission tomography (PET) imaging and magnetic resonance lymphography (MRL) with iron oxide particles are promising for nodal staging of prostate cancer. In this review, the strengths and limitations of imaging techniques for lymph node staging of prostate cancer are discussed.

    BACKGROUND: Intraoperative analysis of sentinel lymph nodes would enhance the care of early-stage oral squamous cell carcinoma (OSCC). We determined the frequency and extent of cytokeratin 19 (CK19) expression in OSCC primary tumours and surrounding tissues to explore the feasibility of a "clinic...... mg). CK19 assays included qRT-PCR, RNA in situ hybridisation (ISH), and immunohistochemistry (IHC), as well as OSNA. RESULTS: CK19 mRNA expression was detected with variable sensitivity, depending on method, in 60-80% of primary OSCC tumours, while protein expression was observed in only 50......% of tumours. Discordance between different techniques indicated that OSNA was more sensitive than qRT-PCR or RNA-ISH, which in turn were more sensitive than IHC. 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...

  10. THE LYMPH SELF ANTIGEN REPERTOIRE

    2013-12-01

    Full Text Available The lymphatic fluid originates from the interstitial fluid which bathes every parenchymal organ and reflects the omic composition of the tissue from which it originates in its physiological or pathological signature. Several recent proteomic analyses have mapped the proteome-degradome and peptidome of this immunologically relevant fluid pointing to the lymph as an important source of tissue-derived self-antigens. A vast array of lymph-circulating peptides have been mapped deriving from a variety of processing pathways including caspases, cathepsins, MMPs, ADAMs, kallikreins, calpains and granzymes, among others. These self peptides can be directly loaded on circulatory dendritic cells and expand the self-antigenic repertoire available for central and peripheral tolerance.

  11. Hormonal Modulation of Breast Cancer Gene Expression: Implications for Intrinsic Subtyping in Premenopausal Women

    Clinics are increasingly adopting gene-expression profiling to diagnose breast cancer subtype, providing an intrinsic, molecular portrait of the tumor. For example, the PAM50-based Prosigna test quantifies expression of 50 key genes to classify breast cancer subtype, and this method of classification has been demonstrated to be superior over traditional immunohistochemical methods that detect proteins, to predict risk of disease recurrence. However, these tests were largely developed and validated using breast cancer samples from postmenopausal women. Thus, the accuracy of such tests has not been explored in the context of the hormonal fluctuations in estrogen and progesterone that occur during the menstrual cycle in premenopausal women. Concordance between traditional methods of subtyping and the new tests in premenopausal women is likely to depend on the stage of the menstrual cycle at which the tissue sample is taken and the relative effect of hormones on expression of genes versus proteins. The lack of knowledge around the effect of fluctuating estrogen and progesterone on gene expression in breast cancer patients raises serious concerns for intrinsic subtyping in premenopausal women, which comprise about 25% of breast cancer diagnoses. Further research on the impact of the menstrual cycle on intrinsic breast cancer profiling is required if premenopausal women are to benefit from the new technology of intrinsic subtyping.

    The effects of hyperprolactinemia on metabolic parameters are not clear and a few data evaluating adiponectin levels in prolactinoma and idiopathic hyperprolactinemia exist. The aim of this study was to evaluate the effects of hyperprolactinemia on body weight, insulin resistance, beta cell function, and leptin and adiponectin levels in premenopausal women with hyperprolactinemia. Forty premenopausal women with prolactinoma or idiopathic hyperprolactinemia were compared to 41 age-matched healthy premenopausal women with regard to body weight, body mass index, waist and hip circumferences, waist to hip ratio, fasting plasma glucose, insulin levels, insulin resistance measured by homeostasis model assessment (HOMA)-insulin resistance index, beta cell function measured by HOMA-β index, leptin and adiponectin levels. Plasma insulin levels and HOMA indexes (both insulin resistance and beta indexes) were significantly higher in hyperprolactinemic women. The other parameters were similar between both groups. There was a positive correlation between prolactin levels and fasting plasma glucose in hyperprolactinemic women. The results of this study showed that high prolactin levels may be associated with hyperinsulinemia and insulin resistance in premenopausal women. This effect seems to be independent of body weight, leptin and adiponectin levels. High prolactin levels may directly stimulate insulin secretion from pancreas and directly cause hepatic and whole-body insulin resistance.

    The increasing incidence of obesity throughout the world will result in expansion of the number of women at risk for developing breast cancer. Obesity is associated with adverse outcomes in postmenopausal women with breast cancer. In premenopausal women, the association is less clear. We investigated the impact of obesity on tumor features, hormonal status, recurrence and mortality in premenopausal breast cancer patients, classified according to molecular subtypes. 818 premenopausal women with nonmetastatic breast cancer were analysed. Patients were classified into 3 groups according to body mass index (BMI): i) normal body weight (BMI: 18.5-24.9 kg/m(2)); ii) overweight (BMI: 25-29.9 kg/ m(2)); and iii) obese (BMI:>30 kg/ m(2)). Clinocopathologic characteristics and survival rates were analyzed for triple negative, HER-2 overexpressing and luminal subtypes. Obese patients compared with normal-weight women were older at diagnosis (pobese patients with triple negative breast cancer (TNBC) (p=0.001 and p=0.006, respectively). Obesity (HR 1.4; 95% CI 1.0-2.1; p=0.04) and lymphovascular invasion (HR 2.1; 95% CI 1.3- 3.3; p=0.02) were found to be independent prognostic factors for TNBC mortality. Obesity is associated with estrogen (ER) and progesterone receptor (PR) negative tumors and poor OS in premenopausal women with breast cancer.

    Evaluation of the nutritional status, fat tissue distribution, and tumor characteristics was carried out in patients with primary breast cancer. The patients were classified into two groups according to their menopause: premenopausal and postmenopausal. Breast cancer prevalence was considerably higher in postmenopausal patients (61%). The patients' nutritional status was shown through the body mass index. Based on this indicator, the patients were characterized as nonobese and obese. In the premenopausal group, there was no significant difference between these categories, whereas the number of obese patients was significantly higher (80%) in the postmenopausal group. The analysis of tumor parameters as related to menopause and body size did not yield any significant differences. However, the estrogen receptor content was significantly higher in postmenopausal patients (p < 0.0001). Distribution of fat tissue of the android type was higher in obese postmenopausal women than in premenopausal ones (77%). The investigation showed that the breast cancer incidence odds are 3.5 times higher in obese postmenopausal than in premenopausal patients.

    Full Text Available Abstract Background Maximisation of the potential of sentinel lymph node biopsy as a minimally invasive method of axillary staging requires sensitive intraoperative pathological analysis so that rates of re-operation for lymphatic metastases are minimised. The aim of this study was to describe the test parameters of the frozen section evaluation of sentinel node biopsy for breast cancer compared to the gold standard of standard permanent pathological evaluation at our institution. Methods The accuracy of intraoperative frozen section (FS of sentinel nodes was determined in 94 consecutive women undergoing surgery for clinically node negative, invasive breast cancer (37:T1 disease; 43:T2; 14:T3. Definitive evidence of lymphatic spread on FS indicated immediate level II axillary clearance while sentinel node "negativity" on intraoperative testing led to the operation being curtailed to allow formal H&E analysis of the remaining sentinel nodal tissue. Results Intraoperative FS correctly predicted axillary involvement in 23/30 patients with lymphatic metastases (76% sensitivity rate permitting definitive surgery to be completed at the index operation in 87 women (93% overall. All SN found involved on FS were confirmed as harbouring tumour cells on subsequent formal specimen examination (100% specificity and positive predictive value with 16 patients having additional non-sentinel nodes found also to contain tumour. Negative Predictive Values were highest in women with T1 tumours (97% and lessened with more local advancement of disease (T2 rates: 86%; T3: 75%. Of those with falsely negative FS, three had only micrometastatic disease. Conclusion Intraoperative FS reliably evaluates the status of the sentinel node allowing most women complete their surgery in a single stage. Thus SN can be offered with increased confidence to those less likely to have negative axillae hence expanding the population of potential beneficiaries.

    The objective of this study is to determine if radiotherapy (RT) alone to the cervical lymphatics is a suitable alternative to elective neck dissection (END) in patients who undergo parotidectomy and postoperative RT for squamous cell carcinoma metastatic to the parotid area lymph nodes (PALN). We retrospectively reviewed the medical records of 107 patients consecutively treated from November 1969 to March 2012 for cutaneous squamous cell carcinoma metastatic to the PALN with a clinically node-negative neck. Primary therapy consisted of parotidectomy in all cases. We compared regional (cervical) control in two subgroups: 42 patients treated with END and RT and 65 patients treated with elective neck irradiation (ENI) alone. The median time of follow-up was 5.5 years (range 0.3-30 years) for all patients and 11 years for living patients (range 1.8-26 years). There was 1 neck recurrence in each subgroup: END and RT, 1/42 (2 %); and ENI alone, 1/65 (1.5 %). No patient experienced a complication related to neck RT. ENI to a dose of approximately 50-60 Gy is a suitable alternative to END and postoperative RT in patients with squamous cell carcinoma metastatic to the PALN.

    As women go through menopause, serum estrogen decreases and ferritin increases. Decreased serum estrogen is well known to cause detrimental effects on bone health; however, data on the associations of serum ferritin with BMD before and after menopause are still lacking. Therefore, this study aimed to investigate the association between serum ferritin levels and BMD in premenopausal and postmenopausal Korean women. This study was performed using data from the 2008-2010 Korean National Health and Nutrition Examination Survey, including 7300 women (4229 premenopausal and 3071 postmenopausal). BMD was measured using dual X-ray absorptiometry at the femur and the lumbar spine, and serum ferritin levels were measured by chemiluminescent immunoassay. Median serum ferritin levels in postmenopausal women were higher than those in premenopausal women despite the same age ranges. Serum ferritin levels were only significantly correlated with BMD on the lumbar spine (β = -0.189, p-value = 0.005) in premenopausal women after adjusting confounding factors. Additionally, BMD on the lumbar spine had tended to decrease as serum ferritin quartiles increase (P for trend = 0.035) in premenopausal women after adjusting confounding factors. On the other hand, there were no significant associations between serum ferritin levels and BMD on the total femur and, femur neck in premenopausal women, and BMD on the total femur, femur neck, and lumbar spine in postmenopausal women. Increased serum ferritin levels were significantly associated with BMD in premenopausal women, particularly on the lumbar spine, but not in postmenopausal women.

    Full Text Available Background: Dry mouth is one of the most common complications during menopause that affects quality of life as well as oral tissue dysfunction. Objective: The aim of this study was to compare the unstimulated salivary flow rate and oral symptoms between premenopausal and postmenopausal women. Methods: This case-control study was conducted in 80 healthy women including 40 postmenopausal women as case group and 40 over 30-year-old premenopausal women as control group. Data were collected through a questionnaire including demographics, oral symptoms and examination. The subjects were asked to avoid eating and drinking 90 minutes before examination. The unstimulated salivary flow rate was measured by spitting method in milliliters per minute. Data were analyzed using Chi-square test, Mann Whitney U test, T-test, and Spearman correlation coefficient. Findings: The mean unstimulated saliva was 0.182±0.149 ml/min and 0.304±0.129 ml/min in postmenopausal and premenopausal women, respectively and the difference was statistically significant. The prevalence of dry mouth was 45% in postmenopausal women and was 12.5% in premenopausal women. Burning sensation in mouth and change in taste sensation were 27.5% and 5% in postmenopausal women and were 2.5% and 0% in premenopausal women. There was negative significant correlation between the unstimulated salivary flow rate and age. Conclusion: The unstimulated salivary flow rate decreases after menopause. Oral symptoms are more prevalent in this period compared to before menopause. These differences may be due to hormonal changes (decreased estrogen and progesterone during menopause.

    AIM: To clarify the relationship between age, menopause, and nonalcoholic fatty liver disease (NAFLD) in women.METHODS: We conducted a follow-up study on nonalcoholic fatty liver disease by using abdominal ultrasonography, and investigated the relationship of age and menopause with the development of NAFLD in women. We followed 1829 women and 2572 men (response rate, 86%) selected in 2001 to represent the non-institutionalized adult population of Gifu, Japan. Data collected included self-reported medical history, lifestyle factors, and menopausal status. The postmenopausal state was defined as beginning 1 year after the cessation of menses. We diagnosed NAFLD with the aid of abdominal ultrasonography by using diagnostic criteria described previously.RESULTS: The prevalence of NAFLD in women increases with age, but does not alter with age in men. Furthermore, the prevalence of NAFLD in premenopausal women (6%) was lower than that in men (24%) and in postmenopausal women (15%). The associations of the postmenopausal state and hormone replacement therapy with NAFLD were statistically significant in a univariate logistic regression model. At the follow-up examination, 67 women (5%) were newly diagnosed with NAFLD. The incidence of NAFLD was 3.5% (28/802) in premenopausal women, 7.5% (4/53) in menopausal women, 6.1% (24/392) in postmenopausal women, and 5.3% (11/206) in women receiving hormone replacement therapy. The weight gain in premenopausal women was equal to that in postmenopausal women. Metabolic syndrome and weight gain were independent risk factors for NAFLD in pre- and postmenopausal women, but age was an independent risk factor in premenopausal women only.CONCLUSION: Aging is a risk factor for NAFLD in premenopausal women, independent of weight gain or influence of metabolic syndrome.

In other countries, particularly Japan, surgical therapy is also recommended for mucinous tumors, tumors with >1000 μm of submucosal invasion, and those with high tumor budding. These histological features have not been well evaluated in a western cohort of pT1 carcinomas. In a cohort of 116 surgically resected pT1 colorectal carcinomas, high tumor budding (P1000 μm (P=0.04), and high-grade morphology (P=0.04) were significantly associated with lymph node metastasis on univariate analysis. Mucinous differentiation, tumor location, tumor growth pattern, and size of invasive component were not significant. On multivariate analysis, only high tumor budding was associated with lymph node metastasis with an odds ratio of 4.3 (P=0.004). A subset of 48 tumors (22 node-positive and 26 node-negative) was analyzed for mutations in 50 oncogenes and tumor suppressors. No statistically significant molecular alterations in these 50 genes were associated with lymph node status. However, lymphatic invasion was associated with BRAF mutations (P=0.01). Furthermore, high tumor budding was associated with mutations in TP53 (P=0.03) and inversely associated with mutations in the mTOR pathway (PIK3CA and AKT, P=0.02). In conclusion, this study demonstrates the importance of identifying high tumor budding in pT1 carcinomas when considering additional surgical resection. Molecular alterations associated with adverse histological features are identified.

    Full Text Available This study aims to evaluate the efficacy and safety of goserelin combined with chemotherapy for premenopausal women with breast cancer. Literatures were extracted from databases including Excerpta Medica Database, Springer, Pubmed, China National Knowledge Infrastructure and Chinese Biological Medicine from their inception up to May 2014. The main efficacy measures were 5 years overall survival (OS, 10 years OS, 5 years disease free survival and 5 years progress free survival. Ten randomized comparison clinical trials were eligible in this study. The result showed that goserelin combined with chemotherapy group can improve the survival rate and decrease the incidence of arthralgia in postmenopausal breast cancer patients, respectively, compared to the control group. However, they can increase the occurrence of vomiting during the chemotherapy process. Compared with the simple chemotherapy, goserelin combined with chemotherapy can provide benefits for premenopausal women with breast cancer on improving the survival rate and reducing arthralgia.

    Full Text Available In the present study, the contribution of various biological and lifestyle factors toward progression to hypertension are examined among menopausal and postmenopausal women. A cross-sectional study among 245 women of 20 to 65 years was conducted. Besides blood pressure, fat percentage using bio-electric impedance analyzer and adiposity indices such as body mass index (BMI, waist–hip ratio (WHR, and waist–height ratio (WHtR were taken. Mean, standard deviation, ANOVA, and multinomial logistic were used to analyze the data. Statistically significant differences (p< .001 for blood pressure among postmenopausal and premenopausal women were found. Among both premenopausal and postmenopausal women, the prehypertensive and hypertensive group showed significant differences with the normotensive women for body weight (p< .005, regional obesity, and general obesity. Low educational level, working status of women, socioeconomic status, nuclear family setup, postmenopausal status, and obesity were found to be the likely risk factors for prehypertension or hypertension among women.

    Breast cancer is a leading cancer diagnosis among premenopausal women around the world. Unlike rates in postmenopausal women, incidence rates of advanced breast cancer have increased in recent decades for premenopausal women. Progress in identifying contributors to breast cancer risk among premenopausal women has been constrained by the limited numbers of premenopausal breast cancer cases in individual studies and resulting low statistical power to subcategorize exposures or to study specific subtypes. The Premenopausal Breast Cancer Collaborative Group was established to facilitate cohort-based analyses of risk factors for premenopausal breast cancer by pooling individual-level data from studies participating in the United States National Cancer Institute Cohort Consortium. This article describes the Group, including the rationale for its initial aims related to pregnancy, obesity, and physical activity. We also describe the 20 cohort studies with data submitted to the Group by June 2016. The infrastructure developed for this work can be leveraged to support additional investigations.

    Pre-menopause in women presents with diverse symptoms, encompassing the tri-dimensional spheres of physical, social and psychological domains, which requires development of appropriate coping strategies to overcome these problems. To assess level of knowledge about tri-dimensional problems in pre-menopausal women and evaluate effectiveness of self instruction module on coping strategies of these problems by pre-test and post-test analysis. In a cross-sectional, community based study, in pre-menopausal women aged 40-49years baseline knowledge of tridimensional problems was assessed in 300 pre-menopausal women, selected by convenient sampling after satisfying selection criteria, by a pre-formed questionnaire. This was followed by administration of a pre-tested, Self-Instructional Module (SIM). The SIM dealt with imparting knowledge about coping strategies regarding pre-menopausal problems and the participants were required to read and retain the SIM. Post-test was conducted using same questionnaire after seven days. Chi-square test/ Paired t-test was used for comparing ratios. A 'p-value' tri-dimensional problems. Such self-instructional module can be used as an effective educational tool in increasing the knowledge of tri-dimensional problems in premenopausal women.

    Osteoporosis, a slowly evolving public health epidemic, often with an insidious presentation is largely preventable but the optimal dimensions of exercise that may be prescribed for enhancing bone-health among premenopausal adults are yet to be elucidated. Hence, the escalating incidence and burden of prevalence of osteoporosis is yet unabated. Considering that exogenous hormones in the form of hormonal contraception are known to modulate bone mass, investigations of their possible influence on the translation of exercise-induced osteogenic stimuli on the mature bone is pertinent. The aim of this study was to examine the effect of specified lifestyle exercise on bone-health of premenopausal women. Premenopausal women (n = 96, mean age: 22.25 ± 3.5 years; mean BMI: 23.43 ± 3.5 kg/m(2)) participated in a 6-month randomised controlled trial involving home-based rest-interspersed bouts of high-impact exercise for the intervention group and sham exercise for the control group. Approximately half (47) of the participants (24-exercise, 23-control) were on hormonal-based contraception while the other half (49: 24-exercise, 25-control) were not on hormonal contraception. The regime led to a significant 3.7 % increase in broadband ultrasound attenuation of exercisers compared to controls; hormonal contraceptive use did not appear to potentiate the osteogenic effects of the lifestyle exercise regime. The research highlights that short, discrete bouts of high-impact exercise may be a potential public health prescription for enhancing premenopausal bone-health regardless of hormonal contraceptive use.

    Mannose-binding lectin (MBL) comprises an oligomeric serum protein that is a member of the collectin class of the C-type lectin superfamily. Its deficiency is genetically determined and confers predisposition to recurrent infections as well as increased infection severity. This correlation has been demonstrated in recurrent furunculosis caused by Staphylococcus aureus, and in pneumococcal and Candida infections. The present study aimed to determine whether there is a correlation between MBL serum levels and recurrent urinary tact infections (UTI) in pre-menopausal women. The present aged-matched double-blind controlled study was conducted in 100 pre-menopausal adult women: 50 who suffered from recurrent UTI and 50 without UTI. The MBL concentration was measured in a single serum sample from each patient using an enzyme-linked immunosorbent assay. MBL serum levels [median (range)] were 2500 (4-12,000) ng/mL and 2105 (4-22,800) ng/mL for the research and control groups, respectively. The results from the two groups were compared and were not statistically different (p 0.4). According to these results, MBL serum levels are not associated with an increased risk for recurrent UTI in pre-menopausal women.

    Full Text Available In order to analyze detailed anthropometric characterisation for risk of breast cancer (BC in premenopausal Uruguayan women, a case-control study was carried out at the Pereira Rossell Women’s Hospital, Montevideo, where 253 incident BC cases and 497 frequency-matched healthy controls were interviewed on menstrual and reproductive story, and a series of body measurements were performed to calculate body composition and somatotype. Odds ratio (OR’s coefficients were taken as estimates of relative risk derived from unconditional logistic regression. Results show a positive association for the fat fraction (OR for highest quartile =4.19, 95% CI (95% Confidence Interval 2.70-6.50 as well as for the fat-to-muscle ratio (OR=4.68, 95% CI 2.98-7.36. Muscle fraction was inversely associated with risk (OR=0.53 95% CI 0.36-0.78. High endomorphism was the only somatotype variable associated to the disease risk (OR=1.69, 95% CI 1.13-2.54, however, losing its association when fat amount was included in the regression model. Stratified analyses by body mass index (BMI levels, bone weight, age groups and number of live births also showed risk increases for the highest fat fractions, displaying significant linear trends. Albeit most of the literature reports a putative slight protective effect for a high BMI in premenopausal women, our results suggest that fat fraction, amount and distribution might play a role as predisposing factors for premenopausal BC.

    Fibroblast growth factor 23 (FGF23) circulates as active protein and inactive fragments. Low iron status increases FGF23 gene expression, and iron deficiency is common. We hypothesized that in healthy premenopausal women, serum iron influences C-terminal and intact FGF23 concentrations, and that iron and FGF23 associate with bone mineral density (BMD). Serum iron, iron binding capacity, percent iron saturation, phosphorus, and other biochemistries were measured in stored fasting samples from healthy premenopausal white (n=1898) and black women (n=994), age 20-55years. Serum C-terminal and intact FGF23 were measured in a subset (1631 white and 296 black women). BMD was measured at the lumbar spine and femur neck. Serum phosphorus, calcium, alkaline phosphatase and creatinine were lower in white women than black women (piron (piron. C-terminal FGF23 correlated inversely with iron (white women r=-0.134, piron iron predicted changes in C-terminal FGF23. Spine BMD correlated with iron negatively (r=-0.076, piron negatively (r=-0.119, piron did not relate to intact FGF23, but was inversely related to C-terminal FGF23. Intact FGF23 correlated with serum phosphorus. In weight-adjusted models, BMD was not related to intact FGF23, C-terminal FGF23 or iron. The influence of iron on FGF23 gene expression is not important in determining bone density in healthy premenopausal women.

    Full Text Available Abstract Context Hyperthyroidism can lead to reduced bone mineral density (BMD and increased fracture risk particularly in postmenopausal women, but the mechanism behind is still unclear. Objective Prospective examination of the influence of thyroid hormones and/or thyroid autoantibodies on BMD in premenopause. Design We have examined 32 premenopausal women with untreated active Graves' disease from time of diagnosis, during 18 months of antithyroid drug therapy (ATD and additionally 18 months after discontinuing ATD. Variables of thyroid metabolism, calcium homeostasis and body composition were measured every 3 months. BMD of lumbar spine and femoral neck were measured at baseline, 18 ± 3 and 36 ± 3 months. Data were compared to base line, a sex- and age matched control group and a group of patients with Hashimoto's thyroiditis treated with non-suppressive doses of levothyroxine. Results The study showed significantly (p Conclusion The results indicated a clinically relevant impact of thyroid function on bone modulation also in premenopausal women with Graves' disease, and further indicated the possibility for a direct action of TRAb on bones.

    Full Text Available Abstract Background There have been few studies examining the associations between menstrual irregularity, androgens and bone mass in population-based samples of premenopausal women. This study aimed to describe the associations between menstrual pattern, testosterone, sex hormone binding globulin (SHBG and bone mass in a population-based sample of premenopausal women. Methods Cross-sectional study (N = 382, mean age 31.5 years. Menstrual pattern was assessed by questionnaire, bone mass measured by quantitative ultrasound (QUS and androgen status was assessed by levels of serum testosterone, SHBG and the free androgen index (FAI. Results Women with irregular cycles (n = 41, 11% had higher free androgen index (FAI, P = 0.01 and higher QUS measurements including speed of sound (SOS, 1%, P Conclusion Irregular menstrual cycles were associated with higher bone mass in this population-based sample of premenopausal women suggesting menstrual disturbance should continue to be evaluated but may be less harmful for bone mass. The association between menstrual irregularity and bone mass was partially mediated by markers of androgen status especially free testosterone.

    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.

    Lymph node status is an important determinant for the management of patients with newly diagnosed prostate cancer. Given the significant limitations of cross-sectional and functional preoperative imaging in the detection of small metastases, pelvic lymph node dissection remains the only reliable staging method in clinically localized prostate cancer. Although lymph node dissection is a well-established form of staging in prostate cancer, controversy remains about indications and the surgical extent of the procedure. Reported practices vary from omitting pelvic lymph node dissection in low-risk disease to routine pelvic lymph node dissection in all radical prostatectomy patients. This review highlights the recent literature concerning pelvic lymphadenectomy in prostate cancer with respect to anatomical extent and oncologic outcome.

    Inguinal lymphadenectomy, unilateral or bilateral, is widely used in cases of vulvar squamous cell carcinoma and melanoma but has a high morbidity. Sentinel lymph node (SLN) biopsy may be used in the management of these patients. The aims of this study were firstly to determine the reliability of SLN biopsy in predicting regional lymph node status and secondly to apply this technique in the routine clinical setting. We prospectively studied 70 women with vulvar malignancies. The first 50 cases were of squamous vulvar cancer and were used to validate the SLN technique in this clinical setting (validation group). Once a satisfactory success rate had been achieved in the validation group, the SLN technique was applied to a further 20 patients with vulvar malignancies, i.e. squamous cell carcinoma (n=12) and melanomas (n=8) (application group). Dynamic and static images were acquired after the injection of 74-148 MBq of a colloidal albumin, and continued until SLN identification. Fifteen minutes before surgery, blue dye injection was administered in a similar manner to the radiocolloid. After incision, a hand-held gamma probe was used to find the SLN. In the validation group, dissection of the SLN was always followed by lymphadenectomy. In the application group, this procedure was only performed if the SLN was positive for metastases. For pathological staging, samples were evaluated using haematoxylin and eosin and immunohistochemistry. In the validation group, lymphoscintigraphy allowed SLN detection in 49/50 patients (98%). Blue dye detected the SLN in 40/50 patients (80%). In 16 patients (33%), the SLN showed metastases in the pathology study. All 33 patients with negative SLN had regional lymph nodes negative for metastases (negative predictive value 100%). In the application group, lymphoscintigraphy showed drainage to an SLN in 19 out of 20 patients (95%) and blue dye demonstrated a stained SLN in 17/20 patients (85%). Seven of the 19 SLN-identified nodes (37

    Purpose Lymph node status is an important predictor of survival in pancreatic cancer. We performed a secondary analysis of RTOG 9704, an adjuvant chemotherapy and chemoradiation trial, to determine the influence of lymph node factors-number of positive nodes (NPN), total nodes examined (TNE), and lymph node ratio (LNR-ratio of NPN to TNE)-on OS and disease-free survival (DFS). Patient and Methods Eligible patients from RTOG 9704 form the basis of this secondary analysis of lymph node parameters. Actuarial estimates for OS and DFS were calculated using Kaplan-Meier methods. Cox proportional hazards models were performed to evaluate associations of NPN, TNE, and LNR with OS and DFS. Multivariate Cox proportional hazards models were also performed. Results There were 538 patients enrolled in the RTOG 9704 trial. Of these, 445 patients were eligible with lymph nodes removed. Overall median NPN was 1 (min-max, 0-18). Increased NPN was associated with worse OS (HR=1.06, p=0.001) and DFS (HR=1.05, p=0.01). In multivariate analyses, both NPN and TNE were associated with OS and DFS. TNE > 12, and >15, were associated with increased OS for all patients, but not for node-negative patients (n =142). Increased LNR was associated with worse OS (HR=1.01, p<0.0001) and DFS (HR=1.006, p=0.002). Conclusion In patients who undergo surgical resection followed by adjuvant chemoradiation, TNE, NPN, and LNR are associated with OS and DFS. This secondary analysis of a prospective, cooperative group trial supports the influence of these lymph node parameters on outcomes after surgery and adjuvant therapy using contemporary techniques.

    Full Text Available As women go through menopause, serum estrogen decreases and ferritin increases. Decreased serum estrogen is well known to cause detrimental effects on bone health; however, data on the associations of serum ferritin with BMD before and after menopause are still lacking. Therefore, this study aimed to investigate the association between serum ferritin levels and BMD in premenopausal and postmenopausal Korean women.This study was performed using data from the 2008-2010 Korean National Health and Nutrition Examination Survey, including 7300 women (4229 premenopausal and 3071 postmenopausal. BMD was measured using dual X-ray absorptiometry at the femur and the lumbar spine, and serum ferritin levels were measured by chemiluminescent immunoassay.Median serum ferritin levels in postmenopausal women were higher than those in premenopausal women despite the same age ranges. Serum ferritin levels were only significantly correlated with BMD on the lumbar spine (β = -0.189, p-value = 0.005 in premenopausal women after adjusting confounding factors. Additionally, BMD on the lumbar spine had tended to decrease as serum ferritin quartiles increase (P for trend = 0.035 in premenopausal women after adjusting confounding factors. On the other hand, there were no significant associations between serum ferritin levels and BMD on the total femur and, femur neck in premenopausal women, and BMD on the total femur, femur neck, and lumbar spine in postmenopausal women.Increased serum ferritin levels were significantly associated with BMD in premenopausal women, particularly on the lumbar spine, but not in postmenopausal women.

    Multicystic peritoneal mesothelioma is an uncommon lesion most frequently encountered in women of reproductive age. Although the pathologic characteristics have been documented, the lymph node status associated with this pathology, the etiopathogenesis and prognosis of which remain unclear, is unknown. We report here the case of a 35-year-old woman with a 5.5 cm multicystic mesothelioma affecting the pelvic peritoneum of the rectum. Involvement by multicystic mesothelioma was observed within two lymph nodes simultaneously resected with the tumor. To the best of our knowledge, lymph node involvement has not been described in previous studies.

    Background It is well accepted that exercise can decrease breast cancer risk. Limited clinical evidence suggests that this risk could be mediated through changes in estrogen metabolism in premenopausal women. Our objective was to investigate the effects of exercise on premenopausal estrogen metabolism pertinent to breast cancer risk. Methods Sedentary, healthy, young eumenorrheic women were randomized into an intervention of 30 minutes of moderate-to-vigorous aerobic exercise 5 times a week for approximately 16 weeks (n = 212), or into a usual-lifestyle sedentary control group (n = 179). Urinary levels of estrogens (estrone [E1], estradiol, and estriol) and nine estrogen metabolites were measured at baseline and at study end by liquid chromatography/tandem mass spectrometry. The ratios of 2-hydroxyestrone to 16α-hydroxyestrone (2-OHE1/16α-OHE1) and 2-OHE1 to 4-hydroxyestrone (2- OHE1/4-OHE1) were also calculated. Results The exercise intervention resulted in significant increases in aerobic fitness and lean body mass, and a significant decrease in percent body fat. For exercisers who completed the study (n = 165), 2-OHE1/16α-OHE1 increased significantly (P = 0.043), while E1 decreased significantly (P = 0.030) in control participants (n = 153). The change from baseline in 2-OHE1/16α-OHE1 was significantly different between groups (P = 0.045), even after adjustment for baseline values. Conclusions The exercise intervention resulted in a significant increase in the 2-OHE1/16α-OHE1 ratio, but no differences in other estrogen metabolites or ratios. Impact Our results suggest that changes in premenopausal estrogen metabolism may be a mechanism by which increased physical activity lowers breast cancer risk. PMID:23652373

    One goal of osteoporosis research is to identify the genes and environmental factors that contribute to low bone mineral density (BMD) and fracture. Linkage analyses have identified quantitative trait loci (QTLs), however, the genes contributing to low BMD are largely unknown. We examined the potential association of an intronic polymorphism in CD38 with BMD and postmenopausal bone loss. CD38 resides in 4p15, where a QTL for BMD has been described. CD38-\\/- mice display an osteoporotic phenotype at 3 months, with normalization of BMD by 5 months. The CD38 polymorphism was identified by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 457 postmenopausal and 173 premenopausal Caucasian women whose spine and hip BMD was measured by dual energy X-ray absorptiometry (DXA). Influence of the CD38 polymorphism on bone loss was analyzed in 273 postmenopausal women over a follow-up of 2.94 +\\/- 1.50 years. The CD38-PvuII polymorphism was significantly associated with premenopausal and postmenopausal (P = 0.001) lumbar spine BMD. Women homozygous for the G allele had >14% lower spinal BMD than women with GC\\/CC genotypes. An allele dose effect was observed at the spine in premenopausal (P = 0.002) and postmenopausal (P < 0.001) cohorts. The CD38-PvuII polymorphism was significantly associated with femoral neck BMD in pre- and postmenopausal women (P = 0.002 and P = 0.011, respectively). However, significance was lost following adjustment of hip BMD for covariates in the postmenopausal cohort (P = 0.081). The CD38-PvuII polymorphism was weakly associated with bone loss at the spine (P = 0.024), in postmenopausal women not taking hormone replacement therapy. We suggest that the CD38-PvuII polymorphism may influence the attainment and maintenance of peak BMD and postmenopausal bone loss.

    Full Text Available This study was carried out in 130 women, between 44-55 ages, admitted to outpatient clinic of Physical Medicine and Rehabilitation Department of Trakya University Medical Faculty in order to make. comparison of hormone profile and DEXA values of premenopausal, perimenopausal, and postmenopausal women . Three groups were allocated according to climacteric symptoms and menopause condition. Premenopausal group consisted of women who had regular menstruation and did not have any climacteric symptoms , perimenopausal group consisted of women who had menstruation disorder and climacteric symptoms within one year and postmenopausal group consisted of women who had last menstruation within more than one year and less than 5 years. Women who had prior osteoporosis diognosis and treatment, hormone replacement therapy, surgical menopause and menopause duration more than 5 years were excluded from the study. Age, body weight ,height, hormone profile including estradiol (E2, progesterone (P, follicule stimulating hormone (FSH, luteinizing hormone (LH, parathyroid hormone (PTH, thyroid hormones (T3, T4, thyroid stimulating hormone (TSH and DEXA values representing bone mineral density (BMD of both groups were evaluated. In peri and postmenopausal groups, E2, P, FSH and LH values were significantly lower, while there was no significant difference for PTH and thyroid hormone levels comparing to premenopausal group. For DEXA values, T scores of L2-L4, L2, L3, L4, femur neck, trochanter, Wards and Z scores of femur neck, Wards area were significantly lower in peri and postmenopausal groups. It was demonstrated paralel to literature that BMD decreased in peri and early postmenopausal women associated with hormone profile changes, mainly lower E2.

    Estradiol (E2) plays a key role in human reproduction through the induction of vascular endothelial growth factor (VEGF) and T-regulatory cells (T-Regs), which are also important in breast cancer (BC) growth. The primary endpoint of the present study was the investigation of whether E2 suppression, chemotherapy and radiation therapy decreased the levels of VEGF and T-Regs of premenopausal patients with high-risk early BC. The secondary endpoints were toxicity, progression-free survival (PFS) and overall survival (OS). Between April 2003 and July 2008, 100 premenopausal women with early, high-risk BC were entered into the study. The characteristics of the patients were as follows: median age, 43 years (range, 26-45); median number of positive axillary nodes, 3.3; median Ki-67, 33%. Plasma E2, VEGF and T-Reg were measured at baseline and every year. Treatment comprised luteneizing hormone-releasing hormone (LH-RH) analogue, tailored chemotherapy, radiation therapy and hormonal therapy in oestrogen receptor-positive (ER(+)) tumours. At 4 years, a statistically significant decrease in E2, VEGF and T-Reg levels was observed; the PFS and OS rates were 94 and 98%, respectively. Hot flushes and G1 osteopenia occurred following LH-RH analogue administration, while no unexpected toxicity was observed following chemotherapy. E2 deprivation with an LH-RH analogue, tailored chemotherapy, radiation therapy and hormonal therapy in ER(+) tumours decreased plasma VEGF levels and T-Regs numbers in premenopausal high-risk ER(+) and ER- BC patients. In addition, a favorable impact on PFS and OS was observed.

    Full Text Available Estrogen has multiple effects on lipid and lipoprotein metabolism. We investigated the association between the four common single nucleotide polymorphisms in the estrogen receptor 1 (ESR1 gene locus, -1989T>G, +261G>C, IVS1-397T>C and IVS1-351A>G, and lipid and lipoprotein levels in southern Brazilians. The sample consisted in 150 men and 187 premenopausal women. The women were considered premenopausal if they had regular menstrual bleeding within the previous 3 months and were 18-50 years of age. Exclusion criteria were pregnancy, secondary hyperlipidemia due to renal, hepatic or thyroid disease, and diabetes. Smoking status was self-reported; subjects were classified as never smoked and current smokers. DNA was amplified by PCR and was subsequently digested with the appropriate restriction enzymes. Statistical analysis was carried out for men and women separately. In the study population, major allele frequencies were _1989*T (0.83, +261*G (0.96, IVS1-397*T (0.58, and IVS1-351*A (0.65. Multiple linear regression analyses indicated that an interaction between +261G>C polymorphism and smoking was a significant factor affecting high-density lipoprotein cholesterol (HDL-C levels (P = 0.028 in women. Nonsmoking women with genotype G/C of +261G>C polymorphism had mean HDL-C levels higher than those with G/G genotype (1.40 ± 0.33 vs 1.22 ± 0.26 mmol/L; P = 0.033. No significant associations with lipid and lipoprotein levels in women and men were detected for other polymorphisms. In conclusion, the +261G>C polymorphism might influence lipoprotein and lipid levels in premenopausal women, but these effects seem to be modulated by smoking, whereas in men ESR1 polymorphisms were not associated with high lipoprotein levels.

    Current U.S. recommendations for breast cancer screening of women with at least a 20%-25% lifetime risk of developing breast cancer include contrast material-enhanced magnetic resonance (MR) imaging of the breasts. The cancer detection rate in high-risk women undergoing screening MR imaging is approximately 10 times higher than that in normal-risk women undergoing screening mammography. Many of these high-risk women commence MR imaging screening while they are premenopausal, when the breasts are most influenced by cyclical hormonal changes. Healthy premenopausal breast tissue enhances in a cyclical and variable manner. This enhancement is described as background enhancement. Typically, enhancement of normal breast tissue occurs in a symmetric and diffuse pattern, and there is little diagnostic difficulty in classifying it as normal background parenchymal enhancement. However, sometimes the pattern is more focal, asymmetric, or regional. It may then be described as nonmasslike enhancement, an observation associated with both benign and malignant breast pathologic conditions. A review of the morphologic features and internal enhancement patterns in normal but nondiffuse background enhancement and abnormal nonmasslike enhancement in high-risk premenopausal women can help improve interpretive specificity and decrease false-positive interpretations. MR imaging pitfalls and interpretation strategies for localized background enhancement and pathologic nonmasslike enhancement in this high-risk population are highlighted. In evaluating nonmasslike enhancement, the use of the Breast Imaging Reporting and Data System (BI-RADS) lexicon to perform careful analysis of morphologic features, along with an understanding of the role and limitations of kinetic information, will help balance early breast cancer detection against false-positive interpretation.

    Background Prior studies have found weak inverse associations between breast cancer and caffeine and coffee intake, possibly mediated through their effects on sex hormones. Methods High-performance liquid chromatography/tandem mass spectrometry was used to quantify levels of 15 individual estrogens and estrogen metabolites (EM) among 587 premenopausal women in the Nurses’ Health Study II with mid-luteal phase urine samples and caffeine, coffee and/or tea intakes from self-reported food frequency questionnaires. Multivariate linear mixed models were used to estimate geometric means of individual EM, pathways and ratios by intake categories, and P-values for tests of linear trend. Results Compared to women in the lowest quartile of caffeine consumption, those in the top quartile had higher urinary concentrations of 16α-hydroxyestrone (28% difference; P-trend=0.01) and 16-epiestriol (13% difference; P-trend=0.04), and a decreased parent estrogens/2-, 4-, 16-pathway ratio (P-trend=0.03). Coffee intake was associated with higher 2-catechols, including 2-hydroxyestradiol (57% difference, ≥4 cups/day vs. ≤6 cups/week; P-trend=0.001) and 2-hydroxyestrone (52% difference; P-trend=0.001), and several ratio measures. Decaffeinated coffee was not associated with 2-pathway metabolism, but women in the highest (vs. lowest) category of intake (≥2 cups/day vs. ≤1–3 cups/month) had significantly lower levels of two 16-pathway metabolites, estriol (25% difference; P-trend=0.01) and 17-epiestriol (48% difference; Ptrend=0.0004). Tea intake was positively associated with 17-epiestriol (52% difference; Ptrend=0.01). Conclusion Caffeine and coffee intake were both associated with profiles of estrogen metabolism in premenopausal women. Impact Consumption of caffeine and coffee may alter patterns of premenopausal estrogen metabolism. PMID:26063478

    Objective:This study aims to investigate the correlation between the number of resected lymph nodes (LNs) and the prognosis of patients with node-negative non-small cell lung cancer (NSCLC). Methods:A retrospective review of 305 patients with NSCLC, who received curative resection between January 2004 and December 2009, was conducted. All patients were proved without lymph node involvement histopathologically. The prognostic impact of the number of negative LNs and the clinicopathologic factors were analyzed. Results:The overall median survival time and the 1-, 3-, and 5-year overall survival rates were 60.0 months, 76.1%, 59.3%, and 47.1%, respectively. Survival analysis confirmed that the number of negative LNs, T staging and the stations of the mediasti-nal lymph nodes dissected were showed to be independent prognostic factors. Patients with a high number of negative LNs had better overall survival than patients with a low number of negative LNs (P0.05). Conclusion:The number of negative lymph nodes is an independent prognostic predicting factor for node-negative NSCLC. Sufficient dissection of LNs is recommended to improve the survival of the patients with node-negative NSCLC.%目的:探讨淋巴结清扫数目对无淋巴结转移非小细胞肺癌患者预后的影响。方法:回顾性分析305例无淋巴结转移非小细胞肺癌患者临床病理资料。结果:全组患者中位生存期和5年生存率分别为60.0个月和47.1%。T分期、淋巴结清扫数目和清扫站数是影响本组患者预后的独立预后因素。相同T分期患者生存率随淋巴结清扫数目增加而增高(P0.05)。结论:淋巴结清扫数目是无淋巴结转移非小细胞肺癌患者预后的独立预后因素。术中应清扫足够数目的淋巴结,进而提高患者生存率。

    Sentinel lymph node (SLN) biopsy is the preferred surgical technique for staging the axilla in clinically node-negative breast cancer. Accurate intraoperative staging allows for the immediate performance of an axillary clearance in node-positive patients. We assessed the Metasin assay for the intraoperative analysis of SLNs in a prospective evaluation of 250 consecutive patients undergoing intraoperative SLN analysis at the Breast Unit, University Hospital, Southampton, UK. Metasin uses a quantitative reverse transcription PCR to detect two markers of metastasis: cytokeratin 19 (CK19) an epithelial marker and mammaglobin (MGB) a breast specific marker. Metasin results were compared with the results from routine paraffin block histopathology. Metasin was robust, with a failure rate of <1%, and demonstrated excellent accuracy and reproducibility. The average turnaround time for the Metasin assay was 42 min, the largest variable being the number of nodes assayed. A total of 533 SLNs were evaluated with 75 patients testing positive for MGB and/or CK19. Based on the analysis of individual SLNs, the overall concordance between Metasin and histology was 92.3% (sensitivity 88.7%, specificity 92.9%). When adjusted for tissue allocation bias, the concordance was 93.8% (sensitivity 89.8%, specificity 94.6%). In this evaluation, 57/250 patients (23%) proceeded to axillary clearance based on Metasin results and were considered spared a second operative procedure. Metasin has proven to be an accurate, reproducible and reliable laboratory test. The analysis time is acceptable for intraoperative use, and in comparison to routine histology demonstrates acceptable concordance, sensitivity and specificity.

Recent studies have shown that poverty is a risk factor for osteoporosis. Objective: To determine the prevalence of osteoporosis and its risk factors in a group of premenopausal women of poor economic background in Colombia. Materials and methods: The study comprised 1483 women between 35 and 53 years of age with at least one risk factor for osteoporosis. Demographic characteristics, reproductive factors, comorbidities, and risk factors for osteoporosis were evaluated. Lumbar vertebrae (L2–L4 and the femur neck were assessed using dual-energy X-ray absorptiometry. Results: Of the 1483 patients, 1443 (97.3% had at least one risk factor for osteoporosis and 40 (2.7% had no risk factors. Patients with one risk factor were referred to have a dual-energy X-ray absorptiometry scan, which 795 women completed. Osteopenia was found in 30.5% and osteoporosis in 4.8% of these women. The majority of these women were homemakers, and 18.5% of the patients with osteoporosis were also illiterate (P < 0.001. The risk factors identified in this population were: hypothyroidism (odds ratio [OR] = 5.19, 95% confidence interval [CI]:1.6–16, age over 45 years old (OR = 1.13, 95% CI: 1.0–1.2, a history of malnutrition or low birth weight (OR = 2.35, 95% CI: 1.0–5.2, or early-onset menopause (OR = 3.4, 95% CI: 1.6–7.2.

    The supporting role of urokinase-type plasminogen activator (uPA) and its inhibitor plasminogen activator inhibitor 1 (PAI-1) in migration and invasion is well known. In addition, both factors are key components in cancer cell-related signaling. However, little information is available for uPA and PAI-1-associated signaling pathways in primary cancers and corresponding lymph node metastases. The aim of this study was to compare the expression of uPA and PAI-1-associated signaling proteins in 52 primary breast cancers and corresponding metastases. Proteins were extracted from formalin-fixed paraffin-embedded tissue samples of the primary tumors and metastases. Protein lysates were subsequently analyzed by reverse phase protein array for the expression of members of the PI3K/AKT (FAK, GSK3-β, ILK, pGSK3-β, PI3K, and ROCK) and the MAPK pathways (pp38, pSTAT3, and p38). A solid correlation of uPA expression existed between primary tumors and metastases, whereas PAI-1 expression did not significantly correlate between them. The correlations of uPA and PAI-1 with signaling pathways found in primary tumors did not persist in metastases. Analysis of single molecules revealed that some correlated well between tumors and metastases (FAK, pGSK3-β, ILK, Met, PI3K, ROCK, uPA, p38, and pp38), whereas others did not (PAI-1 and GSK3-β). Whether the expression of a protein correlated between tumor and metastasis or not was independent of the pathway the protein is related to. These findings hint at a complete deregulation of uPA and PAI-1-related signaling in metastases, which might be the reason why uPA and PAI-1 reached clinical relevance only for lymph node-negative breast cancer tissues.

    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.

    DNA methylation is the best characterised epigenetic change so far. However, its role in breast cancer metastasis has not as yet been elucidated. The aim of this study was to investigate the differences between the methylation profiles characterising primary tumours and their corresponding positive or negative for metastasis lymph nodes (LN) and correlate these with tumour metastatic potential. Methylation signatures of Caveolin-1, CXCR4, RAR-β, Cyclin D2 and Twist gene promoters were studied in 30 breast cancer primary lesions and their corresponding metastasis-free and tumour-infiltrated LN with Methylation-Specific PCR. CXCR4 and Caveolin-1 expression was further studied by immunohistochemistry. Tumours were typified by methylation of RAR-β and hypermethylation of Cyclin-D2 and Twist gene promoters. Tumour patterns were highly conserved in tumour-infiltrated LN. CXCR4 and Caveolin-1 promoter methylation patterns differentiated between node-negative and metastatic tumours. Nodal metastasis was associated with tumour and lymph node profiles of extended methylation of Caveolin-1 and lack of CXCR4 hypermethylation. Immunodetection studies verified CXCR4 and Caveolin-1 hypermethylation as gene silencing mechanism. Absence of Caveolin-1 expression in stromal cells associated with tumour aggressiveness while strong Caveolin-1 expression in tumour cells correlated with decreased 7-year disease-free survival. Methylation-mediated activation of CXCR4 and inactivation of Caveolin-1 was linked with nodal metastasis while intratumoral Caveolin-1 expression heterogeneity correlated with disease progression. This evidence contributes to the better understanding and, thereby, therapeutic management of breast cancer metastasis process.

    Compared to white women, premenopausal Chinese-American women have more plate-like trabecular (Tb) bone. It is unclear whether these findings are relevant to postmenopausal women and if there are racial differences in the deterioration of bone microarchitecture with aging. We applied individual trabecula segmentation and finite element analysis to high-resolution peripheral quantitative computed tomography images in premenopausal and postmenopausal Chinese-American and white women to quantify within-race age-related differences in Tb plate-versus-rod microarchitecture and bone stiffness. Race-menopause status interactions were assessed. Comparisons between races within menopause status were adjusted for age, height and weight. Comparisons between premenopausal and postmenopausal women were adjusted for height and weight. Adjusted analyses at the radius indicated that premenopausal Chinese-Americans had a higher plate bone volume fraction (pBV/TV), Tb plate-to-rod ratio (P-R ratio), and greater plate-plate junction densities (P-P Junc.D) versus white women (all p led to 19% greater whole bone stiffness (p white women. Postmenopausal Chinese-American versus white women had greater Ct.Th, Dcort, and relatively intact Tb plates, resulting in similar Tb stiffness but 12% greater whole bone stiffness (p white women. There are advantages in cortical and Tb bone in premenopausal Chinese-American women. Within-race cross-sectional differences between premenopausal and postmenopausal women suggest greater loss of plate-like Tb bone with aging in Chinese-Americans, though thicker cortices and more plate-like Tb bone persists.

    Full Text Available Weight-bearing and resistance physical activities are recommended for osteoporosis prevention, but it is unclear whether an intensity level above current recommendations has a positive effect on adult premenopausal women. Body composition and bone mineral density (BMD by DXA were compared in three groups of women as follows: Sedentary, Maintenance exercise, and federated Sport Team (n=16 for each group. Physical activity was estimated from the International Physical Activity Questionnaire (IPAQ. The groups did not differ in age, height, weight, or body mass index. Bone mineral content and non-fat soft tissue mass were higher and fat mass was lower in the Sport Team group than in the other groups. The same was true for BMD of total skeleton, lumbar spine, femoral neck, and total hip. A test for linear trend of body composition and BMD showed significant results when including all three groups. Simple and multiple regression analyses showed significant associations between physical activity level (or alternatively, years of participation in programmed physical activity and bone mass measures at all sites except for the middle third of radius. It is concluded that a level of physical activity higher than that usually recommended benefits bone health in adult premenopausal women.

    With a prevalence of 15-21%, dyspareunia is one of the most commonly reported sexual dysfunctions in pre-menopausal women under the age of 40. Studies to date have focused primarily on clinical samples, showing that women with dyspareunia report overall sexual impairment, anxiety, and feelings of sexual inadequacy. However, little is known about their body image and genital self-image and few studies have sampled women exclusively from the general population. The aim of the present, controlled study was to investigate body image and genital self-image in a community sample of pre-menopausal women with self-reported dyspareunia. In total, 330 women completed an online survey, of which 192 (58%) had dyspareunia and 138 (42%) were pain-free control women. In comparison to pain-free control women, women with dyspareunia reported significantly more distress about their body image and a more negative genital self-image. Moreover, findings from a logistic regression, in which trait anxiety was controlled for, showed that a more negative genital self-image was strongly and independently associated with an increased likelihood of reporting dyspareunia. These results suggest that, in women with dyspareunia, body image and genital self-image are significantly poorer and would benefit from more attention from both clinicians and researchers.

    Studies conducted on children and adults have pointed to the correlation of BMI (kg/m2) with risk factors for certain diseases. Other studies have stressed a more intense correlation between the risk factors and indicators of subcutaneous fat obtained in other ways. The aim Of the study was to compare the intensity of correlation between the risk factors and triceps and subscapular skinfold thickness in relation to BMI. The study included 53 postmenopausal and 107 premenopausal women, the risk factors were assessed upon systolic and diastolic blood pressure, glucose concentration, triglyceride and cholesterol levels. Statistically significant differences were established in almost all variables referring to premenopausal and postmenopausal women, except in body height, subscapular skinfold thickness and tryglyceride concentration. Significant correlation with the risk factors was detected in BMI and both skinfold thicknesses, while the subscapular thickness correlates more intensively with the risk factors than it is the case with the triceps thickness. The results indicate that BMI equally correlates with risk factors as well as skinfold thickness.

    Young patients with dense breasts have a relatively low-positive biopsy rate for breast cancer (˜1 in 7). South Korean women have higher breast density than Westerners. We investigated the benefit of using a functional and metabolic imaging technique, diffuse optical spectroscopic imaging (DOSI), to help the standard of care imaging tools to distinguish benign from malignant lesions in premenopausal Korean women. DOSI uses near-infrared light to measure breast tissue composition by quantifying tissue concentrations of water (ctH2O), bulk lipid (ctLipid), deoxygenated (ctHHb), and oxygenated (ctHbO2) hemoglobin. DOSI spectral signatures specific to abnormal tissue and absent in healthy tissue were also used to form a malignancy index. This study included 19 premenopausal subjects (average age 41±9), corresponding to 11 benign and 10 malignant lesions. Elevated lesion to normal ratio of ctH2O, ctHHb, ctHbO2, total hemoglobin (THb=ctHHb+ctHbO2), and tissue optical index (ctHHb×ctH2O/ctLipid) were observed in the malignant lesions compared to the benign lesions (p90% sensitivity and specificity. Malignant lesions showed significantly higher metabolism and perfusion than benign lesions. DOSI spectral features showed high discriminatory power for distinguishing malignant and benign lesions in dense breasts of the Korean population.

    There has been limited research about disordered eating in middle-aged women, and to date, few data exist about restrained eating behavior in postmenopausal women. Therefore, the aim of this study was to examine eating behavior with a specific focus on menopause as an associated factor in restrained eating. Beyond this, we were interested in how postmenopausal status and self-esteem would interact to determine eating patterns in women in middle age. We conducted an online survey in women aged between 40 and 66. Eating behavior was assessed with the Eating Disorder Examination-Questionnaire (EDE-Q) in premenopausal (N = 318) and postmenopausal women (N = 250). All participants rated their self-esteem using the Rosenberg Self-Esteem Scale (RSE) and reported their weight, height, waist circumference, and hip circumference. 15.7% of all participants showed clinically meaningful scores on restrained eating. Postmenopausal women showed significantly higher scores on the EDE-Q subscale of restrained eating as compared to premenopausal women, but when controlling for body mass index, however, this finding was no longer significant. Further exploratory analyses suggest that particularly low or high self-esteem levels are associated with restrained eating. Self-esteem might serve as a mediator between menopausal status and restrained eating, however results of these additional analyses were inconsistent. Restrained eating may appear in middle-aged women. Particularly in postmenopausal women, restrained eating might be associated with lower and higher self-esteem.

    Mediterranean diet (MD) has long been suspected to impact on health promotion. Epidemiologic studies reveal the protective role of adherence to this dietary pattern on cancer incidence. However, its association with breast cancer risk remains unclear. Therefore, we aimed to investigate whether adherence to Mediterranean dietary pattern influence on breast cancer risk in postmenopausal and premenopausal women. We performed an electronic search of published studies earlier than Apr 2015 using Pubmed, Google scholar, Cochrane and Scopus databases. The search terms included: breast neoplasm, breast tumors, mammary carcinoma, mammary neoplasm, breast cancer, and Mediterranean diet. Study inclusion criteria were: 1) written in English; 2) with a study arm of MD intervention or MD style assessment; 3) reported the BC risk in premenopausal and postmenopausal women. We summarized the findings of 8 studies in this review, including five cohorts and three case-control studies. Although, cohort studies reported controversial results in this field, case-control studies resulted inverse relation between this Mediterranean dietary pattern and breast cancer risk in pre or/and postmenopausal women. It seems that there is no sufficient data to reach a conclusion about the effect of MD on breast cancer risk in pre and postmenopausal, but there are some evidences suggesting the protective association. More cohort studies in different parts of the world are needed to confirm these results.

    For vulvar Lichen sclerosus (LS) immunological factors, genetic predisposition, and decreased 5 alpha-reductase activity have been discussed as aetiological factors. During the last decade an increase of LS in young women has been suspected. Aim of this study was to evaluate data of premenopausal women with early onset LS to find potential risk factors focussing on the use of oral contraceptives. We retrospectively analyzed the data of 40 premenopausal patients with early onset LS regarding use of oral contraceptives (OCPs), and first occurrence of LS. To compare these data in a case-control study we analyzed a matched control group of 110 healthy women. All our LS patients were using OCPs compared to 73 women (66.4%) in the control group. OCPs with anti-androgenic activity (chlormadinone acetate, cyproterone acetate, dienogest, and drospirenone) were used by 28 (70%) of the LS patients and by 35 (47.9%) of the 73 women using OCPs in the control group. Thus, the odds ratio for early onset LS for women using anti-androgenic OCPs was 2.53 (95% CI: 1.12-5.75). Our data suggest that disturbance of the androgen dependent growth of the vulvar skin by OCPs and especially by OCPs with anti-androgenic properties might trigger the early onset of LS in a subgroup of susceptible young women.

    Full Text Available Background and Objectives: The best way to prevent osteoporosis, at old age is to prevent bone loss and at young age is trying to keep bones healthy, therefore the aim of this study was to determine the effect of combined exercise on bone mineral density of premenopausal females. Materials and Methods: This semi-experimental study was conducted among 20 premenopausal females between 40 and 45 years old, which were randomly assigned to two groups (experimental and control groups in Hamadan city, during year 2016. The experimental group completed a 12-week combined exercise-training program (6 weeks in water and 6 weeks on land, three times a week and 70 minutes per session. Before and after the 12 weeks, femoral bone mineral density in all samples was measured by DEXA bone mineral densitometry. Data were analyzed with the SPSS 21 software using descriptive and inferential statistics, such as independent and paired t-test, and Analysis of Covariance (ANCOVA. Results: Bone mineral density of femoral neck and total hip of the experimental group, had significant differences with corresponding areas of the control group (P <0.05. In other words, the results revealed that 12 weeks of combined exercise increases femoral bone mineral density in the experimental group with a significant decrease in the control group. Conclusions: According to the results, to prevent a decrease in bone mineral density during the menopausal period, combined exercises are recommended for females at this age.

    A systematic review is done to determine the efficacy and safety of levonorgestrel-releasing intrauterine systems as a treatment using in premenopausal women with symptomatic uterine leiomyoma. We searched the Medline, Central and ICTRP databases for all articles published from inception through July 2013 that examined the following outcomes: uterine volume, uterine leiomyoma volume, endometrial thickness, then menstrual blood loss, blood haemoglobin, ferritin and hematocrit levels, treatment failure rate, device expulsion rate, hysterectomy rate and side effects. From 645 studies, a total of 11 studies met our inclusion criteria with sample sizes ranging from 10 to 104. Evidence suggested that levonorgestrel-releasing intrauterine systems could decrease uterine volume and endometrial thickness, significantly reduce menstrual blood loss, and increase blood haemoglobin, ferritin and hematocrit levels. There was no evidence for decreasing uterine leiomyoma volume. There were no adverse effects on the ovarian function except for ovarian cysts. Device expulsion rates were low, which associated with leiomyoma size (larger than 3cm) but not with leiomyoma location. Irregular bleeding/spotting was observed at the beginning of the follow-up period and then decreased progressively. Results of this systematic review indicate that levonorgestrel-releasing intrauterine systems may be effective and safe treatment for symptomatic uterine leiomyoma in premenopausal women.

    Full Text Available Triple-negative breast cancers (TNBC are a specific subtype of breast cancers with a particularly poor prognosis. However, it is a very heterogeneous subgroup in terms of clinical behavior and sensitivity to systemic treatments. Thus, the identification of risk factors specifically associated with those tumors still represents a major challenge. A therapeutic strategy increasingly used for TNBC patients is neoadjuvant chemotherapy (NAC. Only a subset of patients achieves a pathologic complete response (pCR after NAC and have a better outcome than patients with residual disease.The aim of this study is to identify clinical factors associated with the metastatic-free survival in TNBC patients who received NAC.We analyzed 326 cT1-3N1-3M0 patients with ductal infiltrating TNBC treated by NAC. The survival analysis was performed using a Cox proportional hazard model to determine clinical features associated with prognosis on the whole TNBC dataset. In addition, we built a recursive partitioning tree in order to identify additional clinical features associated with prognosis in specific subgroups of TNBC patients.We identified the lymph node involvement after NAC as the only clinical feature significantly associated with a poor prognosis using a Cox multivariate model (HR = 3.89 [2.42-6.25], p<0.0001. Using our recursive partitioning tree, we were able to distinguish 5 subgroups of TNBC patients with different prognosis. For patients without lymph node involvement after NAC, obesity was significantly associated with a poor prognosis (HR = 2.64 [1.28-5.55]. As for patients with lymph node involvement after NAC, the pre-menopausal status in grade III tumors was associated with poor prognosis (HR = 9.68 [5.71-18.31].This study demonstrates that axillary lymph node status after NAC is the major prognostic factor for triple-negative breast cancers. Moreover, we identified body mass index and menopausal status as two other promising prognostic factors in

    The aim of this study was to investigate predictability of occult lymph node metastasis (OLM) using metabolic parameters on pretreatment {sup 18}F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET)/CT in squamous cell non-small cell lung carcinoma (SC-NSCLC) patients who were clinically node negative (cN0) before surgery. A total of 63 cN0 SC-NSCLC patients (M/F = 61/2, mean age 64.1 ± 8.0) who underwent curative surgery with lymph node dissection were enrolled in this study. Metabolic tumor volume (MTV) of the primary tumor was obtained with a standardized uptake value (SUV) threshold of 2.5. Total lesion glycolysis (TLG) was calculated by multiplication of the MTV and its SUV{sub mean}. Metabolic parameters (SUV{sub max}, MTV, and TLG) and clinicopathological factors were analyzed for OLM. Of 63 patients, 12 (19.0 %) had OLM. Significantly higher SUV{sub max}, MTV, TLG, and pathological tumor size were observed in patients with OLM. The optimal cutoff values for prediction of OLM determined using a receiver-operating characteristic (ROC) curve were 8.8 for SUV{sub max}, 18.9 cm{sup 3} for MTV, 88.4 for TLG, and 2.8 cm for pathological tumor size. Univariate analysis showed correlation of SUV{sub max}, MTV, and TLG with the rate of OLM. In multivariate analyses, high SUV{sub max} and MTV showed an association with an increased risk of OLM, after adjusting for age, sex, pathological tumor size, T stage, and location. Metabolic parameters on pretreatment {sup 18}F-FDG PET/CT were significant predictors for OLM in cN0 SC-NSCLC patients. Surgical planning can be tailored based on the parameters in order to reduce the risk of hidden residual lymph node metastases in patients. (orig.)

    Lymph node metastases are important determinants in the prognosis of primary colorectal cancer. Although it has been established that enlarged, palpable lymph nodes contain metastases in less than half of the cases, no definitive data concerning the incidence of metastases in lymph nodes measuring 5 mm or less are available. We treated the surgical specimens of 52 consecutive patients who had colon cancer with a lymph node clearance technique at the Roswell Park Memorial Institute, Buffalo. We found 2699 lymph nodes in the 52 specimens, with a mean of 52 lymph nodes per specimen (range, five to 151). Sixty-four lymph nodes were found with metastases in 21 (40%) of the 52 patients. Fifty-nine of 64 of the lymph nodes were reexamined and remeasured. Thirty-nine lymph node metastases measured less than 5 mm, 13 were between 5 and 10 mm, and eight were larger than 10 mm. We concluded that lymph node metastases in colon cancer occur most frequently in lymph nodes measuring less than 5 mm (small lymph nodes). The use of lymph node clearing techniques in surgical specimens improves detection of small lymph node metastases and thereby diminishes understaging.

    Menopause is associated with an accelerated decline in vascular function; however, whether this is an effect of age and/or menopause and how exercise training may affect this decline remains unclear. We examined a range of molecular measures related to vascular function in matched premenopausal and postmenopausal women before and after 12 wk of exercise training. Thirteen premenopausal and 10 recently postmenopausal [1.6 ± 0.3 (means ± SE) years after final menstrual period] women only separated by 3 yr (48 ± 1 vs. 51 ± 1 yr) were included. Before training, diastolic blood pressure, soluble intercellular adhesion molecule-1 (sICAM-1), and skeletal muscle expression of thromboxane A synthase were higher in the postmenopausal women compared with the premenopausal women, all indicative of impaired vascular function. In both groups, exercise training lowered diastolic blood pressure, the levels of sICAM-1, soluble vascular adhesion molecule-1 (sVCAM-1), as well as plasma and skeletal muscle endothelin-1. The vasodilator prostacyclin tended (P = 0.061) to be higher in plasma with training in the postmenopausal women only. These findings demonstrate that already within the first years after menopause, several biomarkers of vascular function are adversely altered, indicating that these biomarker changes are more related to hormonal changes than aging. Exercise training appears to have a positive impact on vascular function, as indicated by a marked improvement in the biomarker profile, in both premenopausal and postmenopausal women.

    Full Text Available During the life cycle of a woman's body figure is changed gradually, but on reaching middle age, as a result of follicular loss of ovarian function among others, are emphasized the physiological changes and increase health risk and welfare. Androgyny in association with obesity increases the risk for diabetes, hypertension, dyslipidemia, atherosclerosis, cardiovascular disease, gallstones, osteoarthritis, arthritis, cancers and other disorders of female middle age. Physical activity has gained importance increasing in therapy in the climacteric. It has demonstrated the positive effects of exercise on cardiovascular disease and weight maintenance. This study investigates the influence of a physical activity program for five months on cardiovascular risk factors like high blood pressure and body composition in premenopausal women. The study included 20 premenopausal women, separated into two groups: younger than 35 years (n = 10, and over 35 years (n = 10. The experimental subjects underwent an assessment of blood pressure and body composition before and after an aerobic training. Results indicate greater extent in reducing diastolic blood pressure and body fat in over 35 years premenopausal women. Therefore, performing aerobics, step and toning improves factors cardiovascular risk as high blood pressure and body composition in over 35 premenopausal women.

    The main aim of this study was to investigate possible associations between measures of offspring size at birth in the most recent pregnancy before premenopausal breast cancer diagnosis and the risks of maternal breast cancer mortality, taking tumor characteristics into account. We also aimed to investigate if these associations are modified by age at childbirth, time since childbirth, parity, and age at diagnosis. We followed 6,019 women from their date of premenopausal breast cancer (diagnosed from 1992 to 2008) until emigration, death or December 31st, 2009, whichever occurred first. We used Cox proportional hazard regression models, adjusted for parity, age at diagnosis, and education level, to estimate associations between women pregnancy, cancer characteristics and offspring birth characteristics, and mothers' mortality risk. In stratified analyses, mortality risks were estimated by tumor stage, ER or PR status. There was no association between offspring birth weight (HR = 1.00, 95 % CI 0.99-1.01, when used as a continuous variable), birth weight for gestational age or ponderal index, and premenopausal breast cancer mortality. Similarly, in analyses stratified by tumor stage, receptor status, and time difference between last pregnancy and date of diagnosis, we found no associations between birth size and breast cancer mortality. Our findings suggest that the hypothesis that "premenopausal breast cancer mortality is associated with offspring birth characteristics in the most recent pregnancy before the diagnosis" may not be valid. In addition, these associations are not modified by tumor characteristics.

    In addition to inhibiting coronary atherosclerosis, estrogen is expected to have protective effects on cardiac myocytes. We investigated the difference in myocardial functional parameters evaluated by gated myocardial SPECT after adenosine-stress between post-menopausal and pre-menopausal healthy women. This study included 22 healthy post-menopausal women (mean age: 53.0 yr) and 20 pre-menopausal women (mean age: 43.0 yr) who performed Tc-99m tetrofosmin gated myocardial SPECT after adenosine-stress. Measured hemodynamic parameters, EDV, ESV, stroke volume, EF, cardiac output and cardiac index were compared between the two groups. For comparison, similar-aged two male groups with matched numbers were also studied. There was no significant difference in hemodynamic parameters. EDV, ESV, stroke volume, EF, or cardiac output between the post-menopausal and pre-menopausal women. However, post-menopausal women have a smaller cardiac index (mean: 1.95 L/min/m2 vs 2.20 L/min/m2; p=0.045) and adenosine-induced HR increase (mean : 80.5/min vs 89.7/min ; p=0.03), compared to the pre-menopausal women. On the contrary, the two male groups of the same age range and numbers with the women groups showed no significant difference in any myocardial parameters. These results suggest that menopause may be correlated with reduced increase in cardiac index and HR increase after adenosine-stress.

    Summary: Anthracosis is defined as black, dense pigments in tissues, usually carbon deposits. We, as surgeons, have to make decisions during surgery to the best of our knowledge and based on what the literature provides us. We present the case of a 30-year-old female patient who underwent abdominoplasty. During surgery, bilateral inguinal pigmented and enlarged lymph nodes were seen. Biopsy of the nodes was done to rule out any malignancy. The results showed tattoo pigments on all lymph nodes. We present this case as tattoo pigment migration, which has been rarely described.

    Full Text Available Abstract Background Whereas it is established that organic pain may induce depression, it is unclear whether pain is more common in healthy subjects with depression. We assessed the prevalence of pain in premenopausal women with major depression (MDD. Subjects were 21- to 45-year-old premenopausal women with MDD (N = 70; age: 35.4 +/- 6.6; mean +/- SD and healthy matched controls (N = 36; age 35.4 +/- 6.4 participating in a study of bone turnover, the P.O.W.E.R. (Premenopausal, Osteopenia/Osteoporosis, Women, Alendronate, Depression Study. Methods Patients received a clinical assessment by a pain specialist, which included the administration of two standardized forms for pain, the Brief Pain Inventory – Short Form, and the Initial Pain Assessment Tool, and two scales of everyday stressors, the Hassles and Uplifts Scales. In addition, a quality-of-life instrument, the SF-36, was used. The diagnosis of MDD was established by a semi-structured interview, according to the DSM-IV criteria. Substance P (SP and calcitonin-gene-related-peptide (CGRP, neuropeptides which are known mediators of pain, were measured every hour for 24 h in a subgroup of patients (N = 17 and controls (N = 14. Results Approximately one-half of the women with depression reported pain of mild intensity. Pain intensity was significantly correlated with the severity of depression (r2 = 0.076; P = 0.04 and tended to be correlated with the severity of anxiety, (r2 = 0.065; P = 0.07, and the number of depressive episodes (r2 = 0.072; P = 0.09. Women with MDD complained of fatigue, insomnia, and memory problems and experienced everyday negative stressors more frequently than controls. Quality of life was decreased in women with depression, as indicated by lower scores in the emotional and social well-being domains of the SF-36. SP (P Conclusion Women with depression experienced pain more frequently than controls, had a lower quality of life, and complained more of daily stressors

    Endogenous estrogens and estrogen metabolism are hypothesized to be associated with premenopausal breast cancer risk but evidence is limited. We examined 15 urinary estrogens/estrogen metabolites and breast cancer risk among premenopausal women in a case-control study nested within the Nurses' Health Study II (NHSII). From 1996 to 1999, urine was collected from 18,521 women during the mid-luteal menstrual phase. Breast cancer cases (N = 247) diagnosed between collection and June 2005 were matched to two controls each (N = 485). Urinary estrogen metabolites were measured by liquid chromatography-tandem mass spectrometry and adjusted for creatinine level. Relative risks (RR) and 95% confidence intervals (CI) were estimated by multivariate conditional logistic regression. Higher urinary estrone and estradiol levels were strongly significantly associated with lower risk (top vs. bottom quartile RR: estrone = 0.52; 95% CI, 0.30-0.88; estradiol = 0.51; 95% CI, 0.30-0.86). Generally inverse, although nonsignificant, patterns also were observed with 2- and 4-hydroxylation pathway estrogen metabolites. Inverse associations generally were not observed with 16-pathway estrogen metabolites and a significant positive association was observed with 17-epiestriol (top vs. bottom quartile RR = 1.74; 95% CI, 1.08-2.81; P(trend) = 0.01). In addition, there was a significant increased risk with higher 16-pathway/parent estrogen metabolite ratio (comparable RR = 1.61; 95% CI, 0.99-2.62; P(trend) = 0.04). Other pathway ratios were not significantly associated with risk except parent estrogen metabolites/non-parent estrogen metabolites (comparable RR = 0.58; 95% CI, 0.35-0.96; P(trend) = 0.03). These data suggest that most mid-luteal urinary estrogen metabolite concentrations are not positively associated with breast cancer risk among premenopausal women. The inverse associations with parent estrogen metabolites and the parent estrogen metabolite/non-parent estrogen metabolite ratio

    clinicopathology and prognosis of node-negative esophageal carcinoma patients. The purpose of this study was to investigate the effect of the tumor length on clinicopathology and prognosis of node-negative esophageal carcinoma patients.Methods:The clinicopathological characteristics and survival time of 686 node-negative esophageal carcinoma patients, conifrmed by surgical pathology specimens in the First Afifliated Hospital of Nanjing Medical University from Jan. 2008 to Dec. 2010, were retrospectively analyzed. The optimal cut-off value was determined by decision tree model. Univariate and multivariate methods were used to analyze the prognostic factors of node-negative esophageal carcinoma patients.Results:In decision tree analysis, esophageal tumor length was correlated with an increasing hazard ratio for death with a cut-off value at 3 cm. No signiifcant differences were found in gender, onset age, lesion site and pathological type between 2 groups which were patients with tumor length≤3 cm and tumor length >3 cm (P>0.05). The only 1 difference between 2 groups was T stage (P3 cm were 95.7%, 84.4%, 76.1% and 88.3%, 57.8%, 46.5% respectively, and the difference was statistically signiifcant (P3 cm as T3. Tumor length is an important prognostic factor for esophageal carcinoma patients without lymphatic metastasis.

    Full Text Available We aimed at the evaluation of the relationship between adipocyte fatty acid binding protein (A-FABP and cardiometabolic risk factors in premenopausal and postmenopausal women. Additionally, we compared A-FABP with adipokines related to metabolic syndrome (MetS such as leptin and adiponectin. 94 premenopausal and 90 early postmenopausal middle-aged Caucasian women were subject to examinations. Postmenopausal women had higher A-FABP than premenopausal; this difference became insignificant after controlling for age. We found significantly higher correlation coefficients between A-FABP and TC/HDL-C ratio and number of MetS components in premenopausal women, compared to postmenopausal. Each 1 ng/dL increase in A-FABP concentration significantly increased the probability of occurrence of atherogenic lipid profile in premenopausal women, even after multivariate adjustment. All odds ratios became insignificant after controlling for BMI in postmenopausal women. A-FABP was more strongly associated with MetS than leptin and adiponectin in premenopausal women. Adiponectin concentration was a better biomarker for MetS after menopause. Our results suggest that the A-FABP is more strongly associated with some cardiometabolic risk factors in premenopausal than in postmenopausal women. Higher values of A-FABP after menopause are mainly explained by the fact that postmenopausal women are older. Because of the limitation of study, these results should be interpreted with caution.

    The histopathological lymph node staging is of crucial importance for the prognosis estimation and therapy stratification in gastrointestinal cancer. However, the recommended numbers of lymph nodes that should be evaluated are often not reached in routine practice. Methylene blue assisted lymph node dissection was introduced as a new, simple and efficient technique to improve lymph node harvest in gastrointestinal cancer. This method is inexpensive, causes no delay and needs no toxic substances. All studies performed revealed a highly significantly improved lymph node harvest in comparison to the conventional technique. Moreover, this technique can be combined with a new ex vivo sentinel lymph node mapping that for the first time is based on histological sentinel lymph node detection. The success rate of this method is similar to conventional techniques and it enables an efficient application of extended investigation methods, such as immunohistochemistry or the polymerase chain reaction.

    This study is to find out the histopathological characteristics of lymph node sinus containing blood. Routine autopsy was carried out in the randomly selected 102 patients(among them,100 patients died of various diseases, and 2 of non-diseased causes),their superficial lymph nodes locating in the bilateral neck, axilla, inguina, thorax and abdomen were sampled. Haematoxylin-eosin staining was performed on 10% formalin-fixed and paraffin-embedded lymph node tissue sections(5μm).The histological characteristics of the lymph node sinuses containing blood were observed under light microscope. Among the 1362 lymph nodes sampled from the 100 autopsies, lymph sinuses containing blood were found in 809 lymph nodes sampled from 91 cases, but couldn't be seen in the lymph nodes sampled from the non-diseased cases. According to histology, five kinds of lymph sinuses containing blood were found:vascular-opening sinus, blood-deficient sinus, erythrophago-sinus, blood-abundant sinus, and vascular-formative sinus. It is concluded that in the state of disease, the phenomenon of blood in the lymph sinus is not uncommon. Blood could possibly enter into lymph sinus through lymphatic-venous communications between the veins and sinuses in the node. Lymph circulation and blood circulation could communicate with each other in the lymph sinus.

    Ovarian failure may be a long-term consequence of cancer treatment for premenopausal women. Caused by several treatments, including radiation therapy and the alkylating agents, it produces signs and symptoms associated with menopause: hot flashes, amenorrhea, dyspareunia, loss of libido, and irritability. Critical factors that determine ovarian functioning after treatment for cancer are the patient's age at the time of therapy, the amount of radiation that the ovaries received, and the dose of the antineoplastic agent(s). Medical interventions, such as hormonal therapy and surgical repositioning of the ovaries, may maintain ovarian function for some women. Nursing intervention includes assessment, education, and counseling. Counseling focuses on how the prematurely menopausal patient feels about herself as indicated by self-esteem, body image, and sexuality.

  10. Ultrasonography of adnexal causes of acute pelvic pain in pre-menopausal non-pregnant women

    Full Text Available Acute-onset pelvic pain is an extremely common symptom in premenopausal women presenting to the emergency department. After excluding pregnancy in reproductive-age women, ultrasonography plays a major role in the prompt and accurate diagnosis of adnexal causes of acute pelvic pain, such as hemorrhagic ovarian cysts, endometriosis, ovarian torsion, and tubo-ovarian abscess. Its availability, relatively low cost, and lack of ionizing radiation make ultrasonography an ideal imaging modality in women of reproductive age. The primary goal of imaging in these patients is to distinguish between adnexal causes of acute pelvic pain that may be managed conservatively or medically, and those requiring emergency/urgent surgical or percutaneous intervention.

    Sarcopenia, the decline of muscle mass with age, causes impaired gait, disability and falls. It may therefore increase the risk of fracture for osteoporotic women. The aims of this study were to determine the prevalence of sarcopenia in osteopenic and osteoporotic women, and to determine if hormone replacement therapy (HRT), diet, or physical activity (PA) has a role in the prevention of sarcopenia. One hundred and thirty-one premenopausal and 82 postmenopausal (54 taking HRT) healthy women (17-77 years) volunteered for the study. Body composition was measured by dual X-ray absorptiometry (DXA). Sarcopenia was defined as a relative skeletal muscle index (RSMI) (appendicular skeletal muscle mass divided by height) below 5.45 kg/m2. Osteopenia was defined by a densitometric t-score for bone mineral density (BMD) (g/cm2) below -1.0 and osteoporosis by a t-score below -2.5. Nutrient intake was assessed using 3-day food records and physical activity (PA) was measured using the Baecke Physical Activity Questionnaire. Pearson chi-squared, independent t-tests, simple correlation and multiple regression were used to analyze the data. In premenopausal osteopenic women the prevalence of sarcopenia was 12.5%. In postmenopausal women it was 25% for those with osteopenia, and 50% for those with osteoporosis. PA was independently related to RSMI (beta=0.222, p=0.0001), but diet and HRT were not. After adjusting for PA, RSMI was not significantly related to BMD. These data suggest that the relationship between RSMI, BMD and risk of osteoporosis may largely be mediated through participation in PA. Sarcopenia screening simultaneous to BMD examinations by DXA, may be of value in identifying osteoporotic women with sarcopenia, a group that may be most in need of exercise interventions to increase muscle and BMD.

    Full Text Available The aim of this study was to investigate the association between cardiorespiratory fitness and gut microbiota composition in premenopausal women. The participants consisted of 71 premenopausal Finnish women (aged 19–49 years. Gut microbiota were analyzed using flow cytometry, 16S rRNA gene hybridization and DNA-staining. Maximum oxygen uptake (VO2max was assessed by respiratory gas analyzer and body composition by Bioimpdance. We found that participants with low VO2max had lower Bacteroides, but higher Eubacterium rectale-Clostridium coccoides than the high VO2max group (p < 0.05 for all. VO2max was inversely associated with EreC (r = −0.309, p = 0.01 but not with other bacteria. VO2max also negatively correlated with fat% (r = −0.755, p < 0.001, triglycerides (r = −0.274, p = 0.021 and leptin (r = −0.574, p < 0.001. By contrast, EreC was positively associated with fat% (r = 0.382, p = 0.002, dietary fat intake (r = 0.258, p = 0.034, triglycerides (r = 0.390, p = 0.002 and leptin (r = 0.424, p = 0.001, but negatively with carbohydrate intake (r = −0.252, p = 0.034 and HDL (r = −0.26, p = 0.028. After adjusting for age and dietary intake, all the significant associations remained. However, after adjusting for fat%, the associations between VO2max and EreC disappeared. Our results suggest that cardiorespiratory fitness is associated with gut microbiota composition, independent of age and carbohydrate or fat intake. The association between VO2max and EreC, however, appears to be mediated by body fatness.

    Analyzing the large patient cohort of the multicenter AGO-CaRE-1 study, we compared isolated sentinel lymph node dissection (SLND) with radical lymph node dissection (LND) of the groin in relation to recurrence rates and survival. The AGO-CaRE-1 study retrospectively collected data on treatment patterns and follow-up of vulvar cancer patients [International Federation of Gynecology and Obstetrics (FIGO) stage ≥1B] treated at 29 gynecologic cancer centers between 1998 and 2008. This subgroup analysis evaluated the influence of SLND alone on progression-free survival (PFS) and overall survival (OS). In 487 (63.1%) of 772 included patients with tumors smaller than 4 cm, an LND was performed and no metastatic lymph nodes were detected (LN0). Another 69/772 (8.9%) women underwent SLND alone, showing a negative SLN (SLN0). Tumors in the LN0 group were larger and showed a deeper invasion (LN0 vs. SLN0 tumor diameter: 20.0 vs. 13.0 mm, p < 0.001; depth of invasion: 4.0 vs. 3.0 mm, p = 0.002). After a median follow-up of 33 months (0-156), no significant differences in relation to isolated groin recurrence rates (SLN0 3.0% vs. LN0 3.4%, p = 0.845) were detected. Similarly, univariate 3-year PFS analysis showed no significant differences between both groups (SLN0 82.7% vs. LN0 77.6%, p = 0.230). A multivariate Cox regression analysis, including tumor diameter, depth of invasion, age, grading, and lymphovascular space invasion was performed: PFS [hazard ratio (HR) 0.970, 95% confidence interval (CI) 0.517-1.821] and OS (HR 0.695, 95% CI 0.261-1.849) did not differ significantly between both cohorts. This subgroup analysis of the large AGO-CaRE-1 study showed similar results for groin LND and SLND alone with regard to recurrence rates and survival in node-negative patients with tumors <4 cm.

    Clinical stage II/III esophageal cancer (EC), as defined by the Japanese Classification, relapses at a moderately high rate even after curative resection. The number of lymph node metastases is known to be associated with tumor relapse. Recently, the prognostic significance of occult metastatic lymph nodes (MLNs), as well as that of overt MLNs, has been reported. The aim of this study was to investigate the impact of the total number of MLNs including occult MLNs on postoperative relapse in clinical stage II/III EC. One hundred and five patients with clinical stage II/III EC who underwent esophagectomy accompanied by radical lymphadenectomy at the Department of Surgical Oncology in Osaka City University Hospital between January 2000 and October 2008 were included in this study. Occult MLNs, metastases not detected by hematoxylin-eosin staining, were identified by immunohistochemistry (IHC) using antipancytokeratin antibody AE1/AE3. The clinicopathological features of occult MLNs were compared between the relapse and no relapse groups. A total of 6558 lymph nodes (1357 from two-field dissection and 5201 from three-field dissection) were examined by IHC staining; 362 overt MLNs and 143 occult MLNs were detected. The number of occult MLNs increased in proportion to the International Union Against Cancer pathological (p)N-status and pStage. When the number of occult MLNs was added to the number of pNs, the number of total MLNs was associated with postoperative relapse. With respect to tumor, node, metastasis stage, 6 of 22 patients (27%) who were pathological node-negative converted to node-positive by considering total MLNs. The number of N3 patients with relapse increased markedly with restaging by total MLNs. The number of total MLNs, but not overt MLNs, was an independent prognostic factor on multivariate analysis. These results suggest that occult MLNs were often found, and they were associated with postoperative relapse of resectable esophageal cancer. The total

    Malignant melanoma has become a major growing interdisciplinary problem in public health worldwide. Sentinel lymph node excision (SLNE) in conjunction with preoperative SPECT/CT is considered the most sensitive and specific staging test for the detection of micrometastatic melanoma in regional lymph nodes. Among patients with clinically lymph node-negative melanoma, the use of SPECT/CT-aided SLNE compared with SLNE alone has been found to be associated with a higher frequency of metastatic involvement and a higher rate of disease-free survival. The aim of this study was to analyse the cost-effectiveness of SLNE with preoperative SPECT/CT for detecting sentinel lymph nodes versus that of standard SLNE with preoperative lymphoscintigraphy from a single-institution database. Cost-effectiveness analysis of two surgical approaches for SLNE for malignant melanoma at the University Hospital Essen, Skin Cancer Center in Essen, Germany. Between March 2003 and April 2011 464 patients eligible for SLNE were identified. Of these patients, 403 with clinically negative lymph nodes who underwent SLNE with or without preoperative SPECT/CT qualified for subsequent analysis. Between March 2003 and October 2008, 254 patients were operated upon with the standard technique. From November 2008, 149 patients underwent the SPECT/CT technique. Cost analysis showed a mean cost saving of EUR 710.50 when SPECT/CT was added to preoperative imaging. This was achieved by a reduction in operative time (median, Q1;Q3, 40 min, 40;50 min, vs. 45 min, 35;60 min; p = 0.002), hospital stay duration (5 days, 3;8 days, vs. 8 days, 4.5;14.5 days; p < 0.001) and more frequent use of local anaesthesia (90.6 % vs. 70.5 %; p < 0.001). The median cost of SLNE using SPECT/CT was EUR 1,619.7 (Q1;Q3 EUR 1,317.0;2,603.4) and of SLNE without SPECT/CT was EUR 2,330.2 (EUR 1,468.3;4,058.1; p < 0.001), a cost saving of 30.5 %. In patients with cutaneous melanoma, the use of preoperative SPECT/CT-aided SLNE compared

    The case of a 46-year-old woman with lymphangioleiomyomatosis (LAM) involving the supraclavicular, mediastinal, and pelvic lymph nodes in addition to the lungs is reported. Computed tomography incidentally revealed multiple thin-walled pulmonary cysts and low-attenuating masses in the supraclavicular, mediastinal, and retroperitoneal lymph nodes. A biopsy of the supraclavicular mass was performed and diagnosed as LAM histopathologically. The common sites of extrapulmonary LAM include retroperitoneal and mediastinal lymph nodes; however, supraclavicular lymph node involvement is extremely rare.

    The prognostic role of the number of resected lymph nodes (nLNs) in pathologic N0 (lymph node negative) and Nx (no lymph node examined) non-small cell lung cancer (NSCLC) patients remains uncertain. Guidelines for optimal nLNs have not been established. In the current study, we evaluated whether a higher number of resected lymph nodes (LNs) results in better survival in different tumor size categories among NSCLC patients without metastatic LNs. A retrospective study was conducted. Based on nLNs (LN = 0, 1-7, >7) and tumor size (Ta: ≤ 3.5 cm, Tb: >3.5 cm) during surgery, patients were categorized into 6 groups (LN0Ta, LN0Tb, LN1-7Ta, LN1-7Tb, LN7-Ta and LN7-Tb). Survival and multivariate analyses were carried out to determine whether nLNs combined with tumor size was significant for overall survival (OS) or disease free survival (DFS) after adjusting for potential confounders. A total of 428 patients were enrolled in the study. Multivariate analysis demonstrated that nLNs, tumor size and pathological stage were the independent prognosticators for OS and DFS. Data from our study suggested that lung cancer lymphadenectomy with more than 7 LNs removed should be considered a benchmark for surgery or pathology at an early stage. Survival was significantly better in the LN7-Ta group, compared with other 5 groups (pNx NSCLC. The validation of our finding is warranted in further investigation.

    Microvascular transfer of lymph node flaps has recently gained popularity as a treatment for secondary lymphedema often occurring after axillary, groin, or pelvic lymph node dissections. This study aimed to delineate the lymph node contents and pedicle characteristics of the supraclavicular (SC) and thoracodorsal (TD)-based axillary flaps as well as to compare lymph node quantification of surgeon vs pathologist. SC and TD flaps were dissected from fresh female cadavers. The surgeon assessed pedicle characteristics, lymph node content, and anatomy. A pathologist assessed all flaps for gross and microscopic lymph node contents. The κ statistic was used to compare surgeon and pathologist. Ten SC flaps and 10 TD flaps were harvested and quantified. In comparing the SC and TD flaps, there were no statistical differences between artery diameter (3.1 vs 3.2 mm; P = .75) and vein diameter (2.8 vs 3.5 mm; P = .24). The TD flap did have a significantly longer pedicle than the SC flap (4.2 vs 3.2 cm; P = .03). The TD flap was found to be significantly heavier than the SC flap (17.0 ± 4.8 vs 12.9 ± 3.3 g; P = .04). Gross lymph node quantity was similar in the SC and TD flaps (2.5 ± 1.7 vs 1.8 ± 1.2; P = .33). There was good agreement between the surgeon and pathologist in detecting gross lymph nodes in the flaps (SC κ = 0.87, TD κ = 0.61). The SC and TD flaps have similar lymph node quantity, but the SC flap has higher lymphatic density. A surgeon's estimation of lymph node quantity is reliable and has been verified in this study by comparison to a pathologist's examination. Copyright © 2016 Society for Vascular Surgery.

    In order to optimize the technique of lymph dissection, a method of intraoperative mapping of lymph outflow tracts was used with a lymphotropic dye Blue patente V. It allowed better orientation during lymphodissection in operations for gastric cancer. The detection and investigation of the "signal" lymph node as the most probable object of lymphogenic metastazing can improve the accuracy of postoperative staging of gastric cancer. Visualization of the lymph nodes in the preparation made it possible to increase the number of lymph nodes sent for histological investigation.

    Bovine paratuberculosis is a highly prevalent chronic infection of the small intestine in cattle, caused by Mycobacterium avium subspecies paratuberculosis (MAP). In earlier studies we showed the protective effect of Hsp70/DDA subunit vaccination against paratuberculosis. In the current study we set out to measure primary immune responses generated at the site of Hsp70 vaccination. Lymph vessel cannulation was performed to obtain efferent lymph from the prescapular lymph node draining the neck area where the vaccine was applied. Hsp70 vaccination induced a significant increase of CD21(+) B cells in efferent lymph, accounting for up to 40% of efferent cells post-vaccination. Proliferation (Ki67(+)) within the CD21(+) B cell and CD4(+) T cell populations peaked between day 3 and day 5 post-vaccination. From day 7, Hsp70-specific antibody secreting cells (ASCs) could be detected in efferent lymph. Hsp70-specific antibodies, mainly of the IgG1 isotype, were also detected from this time point onwards. However, post-vaccination IFN-γ production in efferent lymph was non-sustained. In conclusion, Hsp70-vaccination induces only limited Th1 type immune responsiveness as reflected in efferent lymph draining the vaccination site. This is in line with our previous observations in peripheral blood. The main primary immunological outcome of the Hsp70/DDA subunit vaccination is B cell activation and abundant Hsp70-specific IgG1 production. This warrants the question whether Hsp70-specific antibodies contribute to the observed protective effect of Hsp70 vaccination in calves.

    Full Text Available Nearly four decades, Rouviere classification, which is a clinically based system, was the only system for cervical adenopathy classification. The best possible classification of cervical nodal disease may be accomplished by using both clinical palpation and also informations provided by imaging, because imaging can reveal clinically silent lymph nodes. most head and neck tumors spread to the neck nodes as a part of their natural history ,depending on the primary site. Up to 80% of patients with upper aerodigestive mucosal malignancies will have cervical nodal metastasis"nat presentation.The occurrence of nodal metastasis has a profound effect on the management and prognosis of the patients .nodal metastasis is the most important prognostic factor in squamous cell carcinoma of the head and neck. In general it decreases the overall survival by half, and extracapsular spread worsens the prognosis by another half. Our purpose in this presentation is to review imaging classification of cervical lymph nodes.

    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.

    Osteoporosis is a complex disease with both genetic and environmental risk factors. A major determinant of osteoporotic fractures is peak BMD obtained during young adulthood. We previously reported linkage of chromosome 1q (LOD = 4.3) with variation in spinal areal BMD in healthy premenopausal white women. In this study, we used a two-stage genotyping approach to identify genes in the linked region that contributed to the variation of femoral neck and lumbar spine areal BMD. In the first stag...

    Background. Serotonin and brain-derived neurotrophic factor (BDNF) are known to be modulators of nociception. However, pain-related connection between yoga and those neuromodulators has not been investigated. Therefore, we aimed to evaluate the effect of yoga on pain, BDNF, and serotonin. Methods. Premenopausal women with chronic low back pain practiced yoga three times a week for 12 weeks. At baseline and after 12 weeks, back pain intensity was measured using visual analogue scale (VAS), and...

    There are a number of studies that have evaluated the relationship between fibromyalgia (FM) and vitamin D deficiency with conflicting results. The aim of this study was to assess vitamin D deficiency in patients with FM and to evaluate the relationship with the common symptoms of FM and levels of serum vitamin D. Forty premenopausal female fibromyalgia patients and 40 age- and sex-matched control subjects were included in the study. The demographic characteristics of all subjects, including age, sex, and body mass index, were recorded. The number of tender points was recorded, and the intensity of the widespread pain of the subjects was measured by the visual analog scale. The activities of daily living component of the Fibromyalgia Impact Questionnaire (FIQ-ADL), was used to assess physical functional capacity. Serum vitamin D was measured in both groups, and vitamin D levels vitamin D deficiency. The vitamin D levels and clinical and laboratory characteristics of the patient and control groups were comparatively analyzed. The relationship between vitamin D levels and clinical findings of the FM patients were also determined. The mean age was 41.23 ± 4.8 and 39.48 ± 4.08 years for the patient and control groups, respectively. The pain intensity, number of tender points, and FIQ-ADL scores were higher in FM patients than in control subjects. The mean levels of vitamin D in the patient and control groups were determined to be 31.97 ± 15.50 and 28.97 ± 13.31 nmol/L, respectively (p > .05). The incidence of vitamin D deficiency was similar between the patient and control groups (67.5% vs. 70%). Vitamin D levels significantly correlated with pain intensity (r = -0.653; p = .001) and FIQ-ADL scores in the FM group (r = -0.344; p = .030). In conclusion, the results of this study indicate that deficiency of vitamin D is not more common in premenopausal female patients with FM than in control subjects without FM. However, the association between pain and vitamin D

    Ovarian steroids, particularly oestrogen, are important factors for fibroid growth. This has provided a rationale for the investigation of hormonal therapies for women with fibroids. This chapter will assess the role of hormonal therapies for pre-menopausal women with fibroids. A comprehensive search of MEDLINE and EMBASE was undertaken in December 2006. Twenty-nine relevant randomized controlled trials and two systematic reviews were found. The included studies assessed gonadotrophin-releasing hormone analogues (GnRHa) alone, GnRHa plus add-back (with either progestagen, tibolone, combined oestrogen and progestagen, or raloxifene) and GnRHa given for at least 3 months prior to surgery for fibroids. Two trials assessed the effects of raloxifene alone. One trial assessed the effects of low-dose mifepristone, and a pilot study assessed the role of the selective progesterone receptor modulator, asoprisinil. GnRHa reduce fibroid and uterine volume and heavy bleeding but are associated with menopausal symptoms and bone loss, which limit long-term use. There is some evidence that add-back therapy, either progestagen, tibolone, combined oestrogen and progestagen, or raloxifene, can reduce the menopausal symptoms associated with GnRHa and/or loss of bone density, but there is insufficient good-quality research to make definitive conclusions. GnRHa given for at least 3 months before fibroid surgery improve pre-operative haemoglobin concentration and haematocrit, reduce uterine and pelvic symptoms, and reduce the rate of vertical incisions during laparotomy. Women undergoing hysterectomy are more likely to have a vaginal than an abdominal procedure. Limited evidence suggests that raloxifene may be useful in older premenopausal women with lower concentrations of background oestradiol. Limited short-term evidence of two progestogenic therapies indicates that low-dose mifepristone may improve quality of life and bleeding in the short term, and asoprisinil may improve bleeding

  18. The negative bone effects of the disease and of chronic corticosteroid treatment in premenopausal women affected by rheumatoid arthritis

    Full Text Available Osteoporosis is a well-known extra-articular complication in rheumatoid arthritis (RA. The chronic corticosteroid treatment, the functional impairment associated with RA and the disease itself appear to be the most relevant determinants. Most of the previous studies involved postmenopausal women, in whom the estrogenic deficiency might amplify the negative effect towards bone of both RA and corticosteroid therapy. We decided to evaluate bone health in a cohort of premenopausal RA patients. The study population includes 47 premenopausal women attending our outpatient clinic for RA and twice as many healthy age-matched control women selected from the hospital personnel. The bone density at the spine and femoral neck were significantly lower in patients with RA as compared with controls. When spine bone mineral density (BMD values were adjusted for the cumulative glucocorticoid (GC dose alone and for the cumulative GC dose plus body mass index (BMI the mean differences between two groups decreased but they remained statistically significant. We found no difference when the spine BMD was adjusted for cumulative GC dose, BMI and health assessment questionnaire. The difference in femoral neck BMD remained statistically significant also after all the same adjustments. In conclusion, our study shows that a BMD deficiency is frequent also in premenopausal women affected by RA, especially at femoral site and that the main determinants of this bone loss are not only the disease-related weight loss, corticosteroid therapy and functional impairment, but also the systemic effects of the disease itself.

    Intake of sugar-sweetened beverages has increased in North America and seems to have several adverse health effects possibly through decreased circulating 25-hydroxyvitamin D (25(OH)D) concentrations. The aim of this cross-sectional study was to evaluate the association between sugar-sweetened beverages intake and 25(OH)D concentrations among premenopausal women. Intake of sugar-sweetened beverages including colas, other carbonated beverages and sweet fruit drinks was assessed using a validated food frequency questionnaire among 741 premenopausal women. Plasma concentrations of 25(OH)D were quantified by radioimmunoassay. The association between sugar-sweetened beverages intake and 25(OH)D concentrations was evaluated using multivariate generalized linear models and Spearman correlations. A higher intake of colas was associated with lower mean 25(OH)D levels (67.0, 63.7, 64.7 and 58.5 nmol/L for never, 3 servings/week, respectively; r = -0.11 (p = 0.004)). A correlation was observed between intake of other carbonated beverages and 25(OH)D concentrations but was not statistically significant (r = -0.06 (p = 0.10)). No association was observed between intake of sweet fruit drinks and 25(OH)D concentrations. This study suggests that high intake of colas may decrease 25(OH)D levels in premenopausal women. Considering the high consumption of these drinks in the general population and the possible consequences of vitamin D deficiency on health, this finding needs further investigation.

    Osteoporosis is a complex disease with both genetic and environmental risk factors. A major determinant of osteoporotic fractures is peak BMD obtained during young adulthood. We previously reported linkage of chromosome 1q (LOD = 4.3) with variation in spinal areal BMD in healthy premenopausal white women. In this study, we used a two-stage genotyping approach to identify genes in the linked region that contributed to the variation of femoral neck and lumbar spine areal BMD. In the first stage, 654 SNPs across the linked region were genotyped in a sample of 1309 premenopausal white women. The most significant evidence of association for lumbar spine (p = 1.3 x 10(-6)) was found with rs1127091 in the GATAD2B gene. In the second stage, 52 SNPs around this candidate gene were genotyped in an expanded sample of 1692 white women. Significant evidence of association with spinal BMD (p 2.5% of the variation in spinal BMD in these women. The 230-kb LD block contains 11 genes, but because of the extensive LD, the specific gene(s) contributing to the variation in BMD could not be determined. In conclusion, the significant association between spinal BMD and SNPs in the 230-kb LD block in chromosome 1q indicates that genetic factor(s) in this block plays an important role in peak spinal BMD in healthy premenopausal white women.

    Estrogen metabolism profiles may play an important role in the relationship between body size and breast carcinogenesis. Previously, we observed inverse associations between current body mass index (BMI) and plasma levels of parent estrogens (estrone and estradiol) among premenopausal women during both follicular and luteal phases. Using data from the Nurses' Health Study II, we assessed whether height, current BMI, and BMI at age 18 were associated with the urinary concentrations of 15 estrogens and estrogen metabolites (jointly referred to as EM) measured during the luteal phase among 603 premenopausal women. We observed inverse associations with total EM for height (P (trend) = 0.01) and current BMI (P (trend) = 0.01), but not BMI at age 18 (P (trend) = 0.26). Six EMs were 18-27% lower in women with a height 68+ versus ≤62 in., primarily in the methylated catechol pathway (P (trend) = 0.04). Eight EMs were 18-50% lower in women with a BMI of 30+ versus estrogen metabolism profiles in premenopausal women. Further studies with timed urine and blood collections are required to confirm and extend our findings.

    Objectives This study aimed to investigate the status of 25-hydroxyvitamin D (25(OH)D) and its association with metabolic syndrome (MS) and different MS components among premenopausal women with systemic lupus erythematosus (SLE) in China. Patients and methods Altogether 113 premenopausal women with SLE and the age-matched healthy cohorts were recruited in this cross-sectional study. Clinical manifestations and laboratory data including serum 25(OH)D concentration were collected. A multivariable analysis was performed to analyze the association of 25(OH)D with MS and its components. Results The prevalence of 25(OH)D deficiency (25(OH)D D, MS and its components demonstrated that the lower level of 25(OH)D was associated with increased MS prevalence (OR = 0.920, p = 0.012), a decreased level of high-density lipoprotein (OR = 1.059, p = 0.033) and a higher level of fasting glucose (OR = 0.810, p = 0.004). These associations were still detectible after adjustment for age, body mass index and SLE-related variables. Conclusion The level of 25(OH)D is associated with MS and its components in premenopausal women with SLE.

    Duodenal neuroendocrine tumors are rare but increasing in incidence and optimal management is hindered by lack of duodenum-specific staging. Duodenal carcinoids were identified in the Surveillance, Epidemiology and End Results tumor registry. Depth of invasion was defined as limited to lamina propria (LP), invading muscularis propria (MP), through muscularis propria (TMP), and through serosa (S). Nine hundred forty-nine patients were identified with majorities being male (57%), white (70%), and node-negative (87%). Tumor size (cm) was less than 1, 47 per cent; 1 to 2, 35 per cent; and greater than 2, 8 per cent with 76 per cent LP. Lymph node (LN) involvement was associated with age, depth of invasion (LP 4%, MP 28%, TMP 54%, and S 57%) and size (less than 1 cm, 3%; 1 to 2 cm, 13%; and greater than 2 cm, 40%). Using the current T staging, LN involvement was: T1 (LP) 2 per cent, T2 (MP or greater than 1 cm) 13 per cent, T3 (TMP) 54 per cent, and T4 (S) 57 per cent. We reclassified current T1 to T1a and current T2 stage to T1b (1 to 2 cm and LP) and T2 (MP or greater than 2 cm). LN metastasis for T1b tumors was 4.7 per cent compared with 20.8 per cent for T2. The resulting TNM classification better defines 5-year disease-specific survival. Our modified staging schema identifies a low-risk group (T1a and T1b) that may be considered for local therapy.

    OBJECTIVE: The aim of this study was to review the outcome of sentinel lymph node biopsy (SLNB) in patients with melanoma and to delineate whether patients with nodular melanoma are more likely to develop nodal recurrence despite negative SLNB. METHODS: Consecutive patients with cutaneous melanoma undergoing SLNB were identified from a departmental database between 1997 and 2005. Factors including demographic data, site, histological subtype, depth and outcome were examined. RESULTS: Of 131 patients, 103 were node negative and eligible for study. The median age was 53 (16-82) years with 46 patients being male (45%) and 57 female (55%). Primary melanoma sites included lower limb (49; 48%), upper limb (29; 28%), head (12; 11%), trunk (7; 7%) and back (6; 6%). The median Breslow thickness was 2mm. Superficial spreading accounted for 43% of melanoma with nodular accounting for 42%. Median follow-up was 40 (3-90) months. Of 20 relapses, seven recurred in the same nodal basin, three were satellite recurrences, one recurred with both satellite and nodal lesions simultaneously, and nine experienced haematogenous spread. Of the eight patients who developed recurrence in the same nodal basin, four were of nodular histological subtype (p=NS). All of the three patients with satellite lesions had nodular melanoma histologically (p=0.02). When nodal and satellite recurrences were combined, eight of 11 were histologically nodular (p=0.01). CONCLUSIONS: This study indicates that lymphatic recurrence occurs more often in SLNB negative patients with nodular melanoma. Further evaluation of the inclusion criteria for sentinel node biopsy is warranted.

    The UICC requires investigation of a minimum of 12 lymph nodes for adequate lymph node staging in colorectal cancer. Despite that, many authors recommend investigation of a larger number, and different techniques, such as fat clearance, have therefore been developed. In this study we introduce a novel technique involving ex vivo lymph node staining with intraarterial methylene blue injection in colon cancer. We compared 14 cases in which methylene injection was used with 14 cases from our records in which conventional investigation techniques were applied. The lymph node harvest differed highly significantly (pmethylene blue group and the unstained group, respectively. The largest difference occurred in the size group 2-4 mm (191 vs 70 lymph nodes). In 6 cases in the unstained group additional embedding of fatty tissue was necessary to reach an adequate number of investigated lymph nodes. Methylene blue injection is a novel and highly effective method that will improve lymph node preparation in colorectal cancer.

    Full Text Available Sentinel lymph node biopsy (SLNB has replaced conventional axillary lymph node dissection (ALND in axillary node-negative breast cancer patients. However, the use of SLNB remains controversial in patients after neoadjuvant chemotherapy (NAC. The aim of this review is to evaluate the feasibility and accuracy of SLNB after NAC in clinically node-positive patients. Systematic searches were performed in the PubMed, Embase, and Cochrane Library databases from 1993 to December 2013 for studies on node-positive breast cancer patients who underwent SLNB after NAC followed by ALND. Of 436 identified studies, 15 were included in this review, with a total of 2,471 patients. The pooled identification rate (IR of SLNB was 89% [95% confidence interval (CI 85-93%], and the false negative rate (FNR of SLNB was 14% (95% CI 10-17%. The heterogeneity of FNR was analyzed by meta-regression, and the results revealed that immunohistochemistry (IHC staining may represent an independent factor (P = 0.04. FNR was lower in the IHC combined with hematoxylin and eosin (H&E staining subgroup than in the H&E staining alone subgroup, with values of 8.7% versus 16.0%, respectively (P = 0.001. Thus, SLNB was feasible after NAC in node-positive breast cancer patients. In addition, the IR of SLNB was respectable, although the FNR of SLNB was poor and requires further improvement. These findings indicate that IHC may improve the accuracy of SLNB.

    To determine the lymphatic drainage pattern using SPECT/CT in clinically node-negative (cN0) patients with vulvar cancer, and to evaluate the possible implications for the extent of inguinal lymph node dissection. A total of 83 patients with vulvar cancer scheduled for sentinel node (SN) biopsy were injected peritumorally with radioactive nanocolloid particles followed by lymphoscintigraphy and SPECT/CT for anatomical localization. The SN and higher-echelon nodes on SPECT/CT were located in different zones in the groin and pelvic region. The groin was divided into five zones according to Daseler et al.: four zones obtained by drawing two perpendicular lines over the saphenofemoral junction and one zone directly overlying this junction. The nodes in the pelvic region were classified into three zones: external iliac/obturator, the common iliac and the paraaortic zones. A total of 217 SNs and 202 higher-echelon nodes were localized on SPECT/CT. All SNs were located in the five zones according to Daseler et al.: 149 (69 %) in the medial superior region, 31 (14 %) in the medial inferior region, 22 (10 %) in the central region, 14 (6.5 %) in the lateral superior region and only 1 (0.5 %) in the lateral inferior region. The higher-echelon nodes were located both in the groin (15 %) and in the pelvic region (85 %). In patients with cN0 vulvar cancer, lymphatic drainage occurs predominantly to the medial regions of the groin. Drainage to the lateral inferior region of the groin is only incidental and in SN-positive patients this zone might be spared in subsequent extended lymph node dissection. This may lead to a decrease in the morbidity associated with this procedure. SPECT/CT is able to personalize lymphatic mapping, providing detailed information about the number and anatomical location of SNs for adequate surgical planning in the groin. (orig.)

    The aim of this study was to determine the relationship between the body mass index (BMI) at a breast cancer diagnosis and various factors including the hormone-receptor, menopause, and lymph-node status, and identify if there is a specific patient subgroup for which the BMI has an effect on the breast cancer prognosis. We retrospectively analyzed the data of 8,742 patients with non-metastatic invasive breast cancer from the research database of Asan Medical Center. The overall survival (OS) and breast-cancer-specific survival (BCSS) outcomes were compared among BMI groups using the Kaplan-Meier method and Cox proportional-hazards regression models with an interaction term. There was a significant interaction between BMI and hormone-receptor status for the OS (P = 0.029), and BCSS (P = 0.013) in lymph-node-positive breast cancers. Obesity in hormone-receptor-positive breast cancer showed a poorer OS (adjusted hazard ratio [HR] = 1.51, 95% confidence interval [CI] = 0.92 to 2.48) and significantly poorer BCSS (HR = 1.80, 95% CI = 1.08 to 2.99). In contrast, a high BMI in hormone-receptor-negative breast cancer revealed a better OS (HR = 0.44, 95% CI = 0.16 to 1.19) and BCSS (HR = 0.53, 95% CI = 0.19 to 1.44). Being underweight (BMI < 18.50 kg/m2) with hormone-receptor-negative breast cancer was associated with a significantly worse OS (HR = 1.98, 95% CI = 1.00–3.95) and BCSS (HR = 2.24, 95% CI = 1.12–4.47). There was no significant interaction found between the BMI and hormone-receptor status in the lymph-node-negative setting, and BMI did not interact with the menopause status in any subgroup. In conclusion, BMI interacts with the hormone-receptor status in a lymph-node-positive setting, thereby playing a role in the prognosis of breast cancer. PMID:28248981

    The effect of a 3-tier intervention including dietary modifications (ie, moderate energy restriction, decreased carbohydrate, increased protein), increased physical activity, and the use of carnitine as a dietary supplement was evaluated on plasma lipids and the atherogenicity of low-density lipoprotein (LDL) particles in a population of overweight and obese premenopausal (aged 20-45 years) women. Carnitine or a placebo (cellulose) was randomly assigned to the participants using a double-blind design. Carnitine supplementation was postulated to enhance fat oxidation resulting in lower concentrations of plasma triglycerides. Seventy women completed the 10-week protocol, which followed a reduction in their energy intake by 15% and a macronutrient energy distribution of 30% protein, 30% fat, and 40% carbohydrate. In addition, subjects increased the number of steps taken per day by 4500. As no differences were observed between the carnitine and placebo groups in all the measured parameters, all subjects were pooled together for statistical analysis. Participants decreased (Pweight, plasma total cholesterol, LDL cholesterol, and triglyceride were decreased by 4.5%, 8.0%, 12.3%, and 19.2% (Pweight loss (weight) associated with reduced caloric intake, lower dietary carbohydrate, and increased physical activity impacts the atherogenicity of LDL.

    Quality of life (QoL) of premenopausal women (PW) was assessed using primary data collected between September and December 2011. A 26-item questionnaire (WHO-QoL BREF) was administered to 285 apparently healthy women selected from two local government areas in Ibadan. The scores were categorized into poor (≤ 79.53) and good (>79.53) QoL. Multiple logistic regressions were used to study factors associated with QoL. The mean score for the overall QoL (OQoL) was 65.18 ± 11.35 (range = 81.25). The Cronbach's alpha for all domains as well as the OQoL were within an acceptable range. The proportion of women with good OQoL was significantly higher in the urban areas (18.2 percent) than in the rural areas (9.2 percent) (p WHO-QoL BREF is a reliable instrument for measuring QoL among PW in Nigeria. Younger PW and women in the urban areas were more likely to have good QoL.

    Alcohol consumption alters carbohydrate and lipid metabolism which are in part regulated by pancreatic and adrenal hormones. The menstrual cycle per se produces changes in several peptide and steroid hormones besides the sex hormones. The authors investigated the effect of moderate alcohol consumption on plasma hormone levels in 40 premenopausal women. The subjects were fed controlled diets containing 35% of calories from fat. In a random crossover design women were given either alcohol or a soft-drink of equal caloric value for 3 menstrual cycles. Fasting blood samples were collected in the third cycle during follicular, ovulatory and luteal phases. Plasma dehydroepiandrosterone-sulphate (DHEA-S), insulin, glucagon and cortisol levels were measured by radioimmunoassay. Moderate alcohol consumption had no effect on plasma insulin and DHEA-S levels but significantly increased glucagon and cortisol levels. Menstrual cycle per se affected plasma glucagon level in that the levels were higher during follicular phase than luteal phase. Thus, changes in carbohydrate and lipid metabolism following alcohol consumption are mediated in part by alterations in hormones involved in their metabolism.

    The purpose of this study is to provide basic data of comparing BMD (bone mineral density) value of preoperative breast cancer patient and postoperative breast cancer patient due to bone loss with radiation/chemical therapy. The participants consisted of 254 breast cancer patients with BMD after having surgery and treatment from March 2007 to September 2013. Except for 84 patients with menopause or hysterectomy and we have analysed 171 patients. The BMD value (lumbar spine and femur) of before and after treatment from PACS by dure-energy X-ray absorptiometry was analyzed. First, we found variation of entire BMD and BMD according to treatment type, and analyzed detailed correlation by using marital status, number of children, presence of feeding, age of menarche, breast cancer therapy types as variable. Data was analyzed by using SPSS for Windows Program (version 18.0). BMD was decreased 7.1% in lumbar spine, 3.1% in femur respectively (p<.01). Also there is relatively high decrement (0.067 g/cm{sup 2}) in group who had just chemotherapy in femur (p<.05). There is decrement depend on marital status, number of children, presence of feeding, age of menarche, breast cancer therapy types but there was no statistical significance. The results show that BMD was decreased after treatment in premenopausal breast cancer patient, patient who had relatively high decrement need to be included high-risk group. As a result, aggressive prevention policy would be necessary.

    Obese premenopausal women with breast cancer have poorer prognosis for long term survival, in part because their tumors are larger at the time of diagnosis than are found in normal weight women. Whether larger tumor mass is due to obesity-related barriers to detection or to effects on tumor biology is not known. This study used polygenic models for obesity and breast cancer to deconstruct this question with the objective of determining whether cell autonomous mechanisms contribute to the link between obesity and breast cancer burden. Assessment of the growth rates of 259 chemically induced mammary carcinomas from rats sensitive to dietary induced obesity (DS) and of 143 carcinomas from rats resistant (DR) to dietary induced obesity revealed that tumors in DS rats grew 1.8 times faster than in DR rats. This difference may be attributed to alterations in cell cycle machinery that permit more rapid tumor cell accumulation. DS tumors displayed protein expression patterns consistent with reduced G1/S checkpoint inhibition and a higher threshold of factors required for execution of the apoptotic cell death pathway. These mechanistic insights identify regulatory targets for life style modifications or pharmacological interventions designed to disrupt the linkage between obesity and tumor burden.

    Purpose We determined the magnetic resonance imaging (MRI) characteristics of normal clitoral anatomy. Materials and Methods A series of MRI studies of 10 healthy, nulliparous volunteers with no prior surgery and normal pelvic examination was studied and the key characteristics of clitoral anatomy were determined. A range of different magnetic resonance sequences was used without any contrast agent. Results The axial plane best revealed the clitoral body and its proximal continuation as the paired crura. The glans was seen more caudal than the body of the clitoris. The bulbs of the clitoris had the same signal as the rest of the clitoris in the axial plane and they related consistently to the other erectile structures. The bulbs, body and crura formed an erectile tissue cluster, namely the clitoris. In turn, the clitoris partially surrounded the urethra and vagina, forming a consistently observed tissue complex. Midline sagittal section revealed the shape of the body, although in this plane the rest of the clitoris was poorly displayed. The coronal plane revealed the relationship between the clitoral body and labia. The axial section cephalad to the clitoral body best revealed the vascular component of the neurovascular bundle to the clitoris. The fat saturation sequence particularly highlighted clitoral anatomy in healthy, premenopausal, nulliparous women. Conclusions Normal clitoral anatomy has been clearly demonstrated using noncontrast pelvic MRI. PMID:15879834

    Background We undertook this study to investigate the association of a genetic polymorphism of the insulin-like growth factor, IGF-I189, on body composition, exercise performance and exercise economy, after controlling for the independent effect of race as assessed by African genetic admixture (AFADM). Methods A total of 114 premenopausal sedentary women were genotyped for IGF-I189, obtaining measures of fat mass, lean body mass, VO2 during cycling and stairclimbing, time on treadmill and leg strength. A quantitative value for AFADM was derived from genotypic information of approximately 40 ancestry informative markers and used as covariate in statistical models. Results After adjusting for AFADM, IGF-I189 was negatively associated with lean body mass (p = 0.029) and lean leg mass (p = 0.050). Leg strength was not associated with the presence/absence of IGF-I189 (p = 0.380), but carriers of the allele demonstrated a longer time on the treadmill (p = 0.015) after adjusting for AFADM. There was also a negative relationship between oxygen uptake during cycling and presence of the IGF-I189 independent of AFADM (p = 0.010). Conclusion Independent of AFADM, individuals with IGF-I189 are more likely to have low leg lean mass and to perform better in activities requiring exercise economy and endurance performance.

    Factors that are associated with pain perception remain incompletely understood, especially in the visceral pain field. Therefore, the current study aimed to investigate possible psychological and biological predictors of visceral pain sensitivity in healthy subjects. In a sample of 59 healthy premenopausal female subjects on hormonal contraceptives, measures of gastrointestinal (GI) symptoms in daily life, trait and state anxiety, depression, serum cortisol concentrations and serum levels of interleukin-6 (IL-6) were obtained, followed by assessment of rectal distension pain sensitivity measures (i.e., rectal distension sensory threshold, pain threshold and pain ratings for discrete rectal distension stimuli). Regression analyses showed that more GI symptoms in daily life predicted a lower pain threshold. Higher levels of state anxiety predicted a lower pain threshold. Higher cortisol concentrations predicted lower pain ratings. IL-6 was positively related to GI symptoms but was a non-significant predictor of pain threshold in the multiple regression analysis. Similar to findings in patients with functional GI symptoms, we showed that subclinical GI symptoms predict visceral pain sensitivity. In line with somatic pain findings, state but not trait anxiety was found to predict visceral pain sensitivity. Our finding on serum cortisol as positive predictor of pain sensitivity might be interpreted in light of immunosuppressive effects of cortisol. Our finding on the role of IL-6 in GI symptoms is promising for understanding GI complaints in patients and needs further investigation. © 2013 European Pain Federation - EFIC®

    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.

    We compare long-term outcomes in patients with node negative early stage breast cancer treated with breast radiotherapy (RT) without the axillary RT field after sentinel lymph node dissection (SLND) or axillary lymph node dissection (ALND). We hypothesize that though tangential RT was delivered to the breast tissue, it at least partially sterilized occult axillary nodal metastases thus providing low nodal failure rates. Between 1995 and 2001, 265 patients with AJCC stages I-II breast cancer were treated with lumpectomy and either SLND (cohort SLND) or SLND and ALND (cohort ALND). Median follow-up was 9.9 years (range 8.3-15.3 years). RT was administered to the whole breast to the median dose of 48.2 Gy (range 46.0-50.4 Gy) plus boost without axillary RT. Chi-square tests were employed in comparing outcomes of two groups for axillary and supraclavicular failure rates, ipsilateral in-breast tumor recurrence (IBTR), distant metastases (DM), and chronic complications. Progression-free survival (PFS) was compared using log-rank test. There were 136/265 (51%) and 129/265 (49%) patients in the SLND and ALND cohorts, respectively. The median number of axillary lymph nodes assessed was 2 (range 1-5) in cohort SLND and 18 (range 7-36) in cohort ALND (P breast RT and SLND alone, experience low AFR or SFR. Our findings, while awaiting mature long-term data from NSABP B-32, support that in patients with negative axillary nodal status such treatment provides excellent long-term cure rates while avoiding morbidities associated with ALND or addition of axillary RT field.

    Observations that dendritic cells (DCs) constitutively enter afferent lymphatic vessels in many organs and that DCs in some tissues, such as the lung, turnover rapidly in the steady state have led to the concept that a major fraction of lymph node DCs are derived from migratory DCs that enter the lymph node through upstream afferent lymphatic vessels. We used the lysozyme M–Cre reporter mouse strain to assess the relationship of lymph node and nonlymphoid organ DCs. Our findings challenge the...

    The benefits of exercise are widely recognized, however physically active women can develop exercise associated menstrual cycle disturbances such as amenorrhea (i.e., estrogen deficiency) secondary to a chronic energy deficiency. To assess the effects of exercise status and estrogen deficiency on osteoprotegerin (OPG) and its relationship to bone resorption in premenopausal exercising women. Cross-sectional study of serum OPG, urinary c-telopeptides (uCTX), urinary estrone 3-glucuronide (E1G), urinary pregnanediol 3-glucuronide (PdG) and bone mineral density (BMD) measured on multiple occasions in 67 women. Volunteers were retrospectively grouped: 1) sedentary menstruating group (SedMen n=8), 2) exercising menstruating group (ExMen, n=36), and 3) exercising amenorrheic group (ExAmen, n=23). One-way ANOVAs were performed, and LSD post-hoc tests were performed when differences were detected. Subjects were similar with respect to age (24.2+/-1.0 years), weight (57.8+/-1.7 kg), and height (164.3+/-1.3 cm) (p>0.05). ExMen and ExAmen groups were more aerobically fit (p=0.003) and had less body fat (p=0.002) than the SedMen group. Resting energy expenditure/fat free mass was lowest (p=0.001) in the ExAmen groups. Mean E1G across the measurement period (peffect of exercise, and that suppressed OPG may play a role in the etiology of increased bone resorption observed in exercising women with chronic estrogen deficiency secondary to hypothalamic amenorrhea.

  8. Randomized trial of bilateral oophorectomy versus tamoxifen in premenopausal women with metastatic breast cancer.

    1986-02-01

    A randomized clinical trial was performed to compare the efficacy of bilateral oophorectomy with that of tamoxifen at a dose of 10 mg twice daily in premenopausal women with metastatic breast cancer, and to examine the efficacy of each as a crossover treatment. Initial treatment responses were seen in ten of 27 patients (37%) treated with oophorectomy and seven of 26 patients (27%) treated with tamoxifen. The difference was not statistically significant. Crossover responses were seen in five of 15 patients (33%) treated with oophorectomy, including three responses in ten prior tamoxifen nonresponders; and two of 18 patients (11%) treated with tamoxifen. Time to progression distributions were not significantly different during initial treatment, and no significant differences in survival were noted. Thus, there was no overall disadvantage to the use of tamoxifen as opposed to oophorectomy as initial hormonal therapy, and a failure to respond to tamoxifen did not preclude a response to subsequent oophorectomy. Exploratory data analysis within subsets indicated consistent differential treatment effects in the visceral dominant patients. Of the 16 such patients treated with oophorectomy, eight (50%) experienced objective responses but there were no responses in the 14 patients treated with tamoxifen. In the nine visceral dominant crossover patients who had not responded to initial tamoxifen, three (33%) subsequently responded to oophorectomy. Time to progression distributions within the visceral dominant subset appeared to be better for the patients treated initially with oophorectomy. However, one must be very cautious in drawing conclusions from exploratory subset analyses, especially with the small sample size. Further studies would be required to test any hypothesis of differential organ site responsiveness.

    The purpose of this 48-week exercise intervention was designed to examine the effects of power and resistance training on bone mineral density (BMD). Premenopausal women were recruited and randomly assigned to either a power (N.=8) or resistance (N.=11) training group. The power exercises included jumping rope, skipping, hopping, and other power-type exercises. The resistance training group performed 8-10 whole-body strengthening exercises at 70% one-repetition maximum (1RM). Before and after the exercise intervention, BMD was measured via dual energy x-ray absorptiometry (DXA) for the total-body, lumbar spine, left femoral neck, and left greater trochanter. Muscular strength was measured by hand grip dynamometer and 1RM of chest press and leg press. Muscular power was assessed by the Margaria-Kalamen stair climb test. Data were analyzed using repeated measures ANOVA. There were no statistical differences between the two training groups for any of the BMD measurements. Chest press strength was different between the two groups, increasing 6.41 and 1.1kg for the resistance and power groups, respectively over the course of the training period (F[1.15]=9.44, P<0.01). There was a significant time effect for leg press 1RM (F[1.15]=6.04, P=0.03). The participants increased by 12.37kg after the 48-week intervention. Hand grip strength also increased after the study intervention (F[1.16]=46.32, P<0.01). The results of this study suggest that power and resistance training are comparable techniques for maintaining bone density.

    Characterization of the normal degree of physiological variation in the metabolomic profiles of healthy humans is a necessary step in the development of metabolomics as both a clinical research and diagnostic tool. This study investigated the effects of the menstrual cycle on (1)H nuclear magnetic resonance (NMR) derived metabolomic profiles of urine and plasma from healthy women. In this study, 34 healthy women were recruited and a first void urine and fasting blood sample were collected from each woman at four different time points during one menstrual cycle. Serum hormone levels were used in combination with the menstrual calendar to classify the urine and plasma samples into five different phases i.e. menstrual, follicular, periovulatory, luteal and premenstrual. The urine and plasma samples were analysed using (1)H NMR spectroscopy and subsequent data were analysed using principal component analysis (PCA) and partial least squares discriminant analysis. PCA of the urine spectra showed no separation of samples based on the phases of the menstrual cycle. Multivariate analysis of the plasma spectra showed a separation of the menstrual phase and the luteal phase samples (R(2) = 0.61, Q(2) = 0.41). Subsequent analysis revealed a significant decrease in levels of glutamine, glycine, alanine, lysine, serine and creatinine and a significant increase in levels of acetoacetate and very low density lipoprotein (VLDL CH(2)) during the luteal phase. These results establish a need to control for metabolic changes that occur in plasma due to the menstrual cycle in the design of future metabolomic studies involving premenopausal women.

    This is the first study to investigate the efficacy of intravenous iron in treating fatigue in nonanemic patients with low serum ferritin concentration. In a randomized, double-blinded, placebo-controlled study, 90 premenopausal women presenting with fatigue, serum ferritin ≤ 50 ng/mL, and hemoglobin ≥ 120 g/L were randomized to receive either 800 mg of intravenous iron (III)-hydroxide sucrose or intravenous placebo. Fatigue and serum iron status were assessed at baseline and after 6 and 12 weeks. Median fatigue at baseline was 4.5 (on a 0-10 scale). Fatigue decreased during the initial 6 weeks by 1.1 in the iron group compared with 0.7 in the placebo group (P = .07). Efficacy of iron was bound to depleted iron stores: In patients with baseline serum ferritin ≤ 15 ng/mL, fatigue decreased by 1.8 in the iron group compared with 0.4 in the placebo group (P = .005), and 82% of iron-treated compared with 47% of placebo-treated patients reported improved fatigue (P = .03). Drug-associated adverse events were observed in 21% of iron-treated patients and in 7% of placebo-treated patients (P = .05); none of these events was serious. Intravenous administration of iron improved fatigue in iron-deficient, nonanemic women with a good safety and tolerability profile. The efficacy of intravenous iron was bound to a serum ferritin concentration ≤ 15 ng/mL. This study was registered at the International Standard Randomized Controlled Trial Number Register (www.isrctn.org) as ISRCTN78430425.

    For cancer prevention, the World Cancer Research Fund and American Institute for Cancer Research (WCRF/AICR) emphasise recommendations to improve individual behaviour, including avoidance of tobacco products, maintaining a lean body mass, participating in physical activity, consuming a plant-based diet, and minimising the consumption of energy-dense foods, such as sodas, red and processed meats and alcohol. In the present study of 275 healthy premenopausal women, we explored the association of adherence scores with levels of three biomarkers of antioxidant and inflammation status: serum C-reactive protein (CRP), serum γ-tocopherol and urinary F2-isoprostane. The statistical analysis applied linear regression across categories of adherence to WCRF/AICR recommendations. Overall, seventy-two women were classified as low ( ≤ 4), 150 as moderate (5-6), and fifty-three as high adherers ( ≥ 7). The unadjusted means for CRP were 2.7, 2.0 and 1.7 mg/l for low, moderate and high adherers (P trend= 0.03); this association was strengthened after adjustment for confounders (P trend= 0.006). The respective values for serum γ-tocopherol were 1.97, 1.63 and 1.45 μg/ml (P trend= 0.02 before and P trend= 0.03 after adjustment). Only for urinary F2-isoprostane, the lower values in high adherers (16.0, 14.5, and 13.3 ng/ml) did not reach statistical significance (P trend= 0.18). In an analysis by BMI, overweight and obese women had higher biomarker levels than normal weight women; the trend was significant for CRP (P trendadherence to the WCRF/AICR guidelines and normal BMI status are associated with lower levels of biomarkers that indicate oxidative stress and inflammation.

    @@ The presence or absence of metastases in the axillary lymph nodes has remained the most powerful prognostic factor in breast carcinoma. Axillary lymph node dissection (ALND) is the standard procedure for obtaining this information. However, postoperative complications are common. Sentinel lymph node (SLN) biopsy has been proposed as a potential alternative to ALND for staging breast carcinoma. This technique has been shown to be sensitive and specific for predicting the status of the axillary lymph nodes.1 Furthermore, it has the potential advantage of decreasing the morbidity associated with ALND.

    Full Text Available Background. Papillary thyroid carcinoma (PTC is the commonest thyroid malignancy originating from the follicle cells in the thyroid. Despite a good overall prognosis, certain high-risk cases as in those with lymph node metastasis (LNM have progressive disease and poorer prognosis. MicroRNAs are a class of non-protein-coding, 19–24 nucleotides single-stranded RNAs which regulate gene expression and these molecules have been shown to play a role in LNM. The integrated analysis of miRNAs and gene expression profiles together with transcription factors (TFs has been shown to improve the identification of functional miRNA-target gene-TF relationships, providing a more complete view of molecular events underlying metastasis process. Objectives. We reanalyzed The Cancer Genome Atlas (TCGA datasets on PTC to identify differentially expressed miRNAs/genes in PTC patients with LNM-positive (LNM-P versus lymph node negative (LNN PTC patients and to investigate the miRNA-gene-TF regulatory circuit that regulate LNM in PTC. Results. PTC patients with LNM (PTC LNM-P have a significantly shorter disease-free survival rate compared to PTC patients without LNM (PTC LNN (Log-rank Mantel Cox test, p = 0.0049. We identified 181 significantly differentially expressed miRNAs in PTC LNM-P versus PTC LNN; 110 were upregulated and 71 were downregulated. The five topmost deregulated miRNAs were hsa-miR-146b, hsa-miR-375, hsa-miR-31, hsa-miR-7-2 and hsa-miR-204. In addition, 395 miRNAs were differentially expressed between PTC LNM-P and normal thyroid while 400 miRNAs were differentially expressed between PTC LNN and normal thyroid. We found four significant enrichment pathways potentially involved in metastasis to the lymph nodes, namely oxidative phosphorylation (OxPhos, cell adhesion molecules (CAMs, leukocyte transendothelial migration and cytokine–cytokine receptor interaction. OxPhos was the most significantly perturbed pathway (p = 4.70E−06 involving

    In 1977 we reported our results of an ongoing randomized clinical trial evaluating early or delayed adjuvant chemotherapy utilizing 5-flourouracil, cytoxan and prednisone in premenopausal patients with recurrent or advanced breast cancer. At that time the group receiving early systemic chemotherapy was shown to have an improved progression-free interval and appeared to have a trend toward improved survival. The results of subsequent analysis after over 4 more years of follow-up indicate however, that while early employment of systemic chemotherapy does indeed prolong the progression-free interval, and while this advantage has been maintained, there is no survival advantage shown for either group of patients.

    Full Text Available Peng-Fei Qiu, Yan-Bing Liu, Yong-Sheng Wang Breast Cancer Center, Shandong Cancer Hospital and Institute, Jinan, Shandong, People’s Republic of China Abstract: Although the 2009 American Joint Committee on Cancer incorporated the internal mammary sentinel lymph node biopsy (IM-SLNB concept, there has been little change in surgical practice patterns due to the low visualization rate of internal mammary sentinel lymph nodes with the traditional injection technique. Meanwhile, as internal mammary lymph nodes (IMLN metastases are mostly found concomitantly with axillary lymph nodes (ALN metastases, previous IM-SLNB clinical trials fail to evaluate the status of IMLN in patients who are really in need (only in clinically ALN negative patients. Our modified injection technique (periareolar intraparenchymal, high volume, and ultrasonographic guidance significantly improved the visualization rate of internal mammary sentinel lymph nodes, making the routine IM-SLNB possible in daily practice. IM-SLNB could provide individual minimally invasive staging, prognosis, and decision-making for breast cancer patients, especially for patients with clinically positive ALN. Moreover, IMLN radiotherapy should be tailored and balanced between the potential benefit and toxicity, and IM-SLNB-guided IMLN radiotherapy could achieve this goal. In the era of effective adjuvant therapy, within the changing treatment approach – more systemic therapy, less loco-regional therapy – clinicians should deliberate the application of regional IMLN therapy.

    Conclusion: The area between these four landmarks is the most frequent location of the sentinel lymph node identified using the radioisotope method. We suggest that this area should be carefully evaluated preoperatively by ultrasound for appropriate surgical planning. A skin incision in this area is also recommended when sentinel lymph node dissection is guided by blue dye.

    The study aimed to examine the applicability of carbon nanoparticles as a tracer for lymph node mapping and the related factors of lymph node and No.8p subgroup metastasis in patients with gastric cancer. Clinical data of 50 patients with gastric cancer, who had not received treatment preoperatively and underwent gastrectomy in Department of Gastrointestinal Surgery, Wuhan Union Hospital, between October 2014 and August 2015, were retrospectively analyzed. These patients were found to have no distant metastasis preoperatively. Thirty-five out of 50 patients were subjected to lymphatic mapping technique using carbon nanoparticles as the tracer, and the rest 15 cases did not experience the lymphatic mapping and served as controls. The sensitivity, specificity, false positive rate and false negative rate were calculated according to the number of lymph nodes, and the staining and metastasis condition of lymph nodes. The diagnostic value of carbon nanoparticles on metastatic lymph nodes was evaluated. The relationship between the metastasis of lymph nodes or subgroup No.8p lymph nodes and clinicopathologic features was analyzed by χ(2)-test or Fisher's exact test. All patients underwent D2 surgery (lymph node dissection including all the group 1 and group 2 nodes) plus the dissection of the subgroup No.8p lymph nodes. It was found that the average number of harvested lymph nodes in lymphatic mapping technique group (45.7±14.5) was greater than that in control group (39.2±11.7), but the difference was not significantly different (P=0.138>0.05). The success rate, the accuracy, sensitivity, specificity and false negative rate was 97%, 57%, 28%, 62% and 72% respectively. The metastasis of lymph nodes was correlated to the depth of cancer invasion (T stage) (P=0.004nanoparticles failed to show good selectivity for metastatic lymph nodes; the result of lymphatic mapping does not achieve a satisfactory performance; the incidence of lymph node metastasis may increase

    A 22-year-old woman presented with a superficial spreading melanoma on her right thigh (tumor thickness 1.0 mm, Clark-Level III). She also had decorative tattoos on her right ankle, right groin and coccyx. The staging results gave no indication for metastases. Intra-operatively, we observed a black pigmented lymph node highly suspicious for metastatic disease, but histological examination excluded metastatic spread and detected the accumulation of black pigment within the lymph node. Clinical differentiation between tattoo pigments and metastatic disease within lymph nodes is not possible. Histological confirmation of an enlarged pigmented lymph node is therefore essential before radical surgery is performed. Hence, accumulation of tattoo pigment within enlarged and pigmented lymph nodes needs to be included into the differential diagnosis and the documentation of decorative tattoos is important during skin cancer screening as well as during the follow-up of melanoma patients.

    The ultimate treatment for end-stage renal disease (ESRD) is orthotopic transplantation. However, the demand for kidney transplantation far exceeds the number of available donor organs. While more than 100,000 Americans need a kidney, only 17,000 people receive a kidney transplant each year (National Kidney Foundation's estimations). In recent years, several regenerative medicine/tissue engineering approaches have been exploited to alleviate the kidney shortage crisis. Although these approaches have yielded promising results in experimental animal models, the kidney is a complex organ and translation into the clinical realm has been challenging to date. In this review, we will discuss cell therapy-based approaches for kidney regeneration and whole-kidney tissue engineering strategies, including our innovative approach to regenerate a functional kidney using the lymph node as an in vivo bioreactor.

    The association of overweight and obesity with premenopausal breast cancer remained unclear, ethnicity could play a role. A MEDLINE and PUBMED search of all studies on obesity and premenopausal breast cancer published from 2000 to 2010 was conducted. Dose-response meta-analysis was used to determine the risk of premenopausal breast cancer associated with different anthropometric measurements in different ethnic groups. For body mass index (BMI), each 5 kg m(-2) increase was inversely associated with the risk of premenopausal breast cancer (RR = 0.95, 95% confidence interval [CI]: 0.94, 0.97). After stratification by ethnicity, the inverse association remained significant only among Africans (RR = 0.95, 95% CI: 0.91, 0.98) and Caucasians (RR = 0.93, 95% CI: 0.91, 0.95). In contrast, among Asian women, a significant positive association was observed. For waist-to-hip ratio (WHR), each 0.1 unit increase was positively associated with premenopausal breast cancer (RR = 1.08, 95% CI: 1.01, 1.16); the largest effect was detected in Asian women (RR = 1.19, 95% CI: 1.15, 1.24), while small effects of 5% and 6% were observed in African and Caucasian women, respectively. Our results suggest the importance of considering both fat distribution and ethnicity when studying premenopausal breast cancer. © 2013 The Authors. obesity reviews © 2013 International Association for the Study of Obesity.

    Observations that dendritic cells (DCs) constitutively enter afferent lymphatic vessels in many organs and that DCs in some tissues, such as the lung, turnover rapidly in the steady state have led to the concept that a major fraction of lymph node DCs are derived from migratory DCs that enter the lymph node through upstream afferent lymphatic vessels. We used the lysozyme M–Cre reporter mouse strain to assess the relationship of lymph node and nonlymphoid organ DCs. Our findings challenge the idea that a substantial proportion of lymph node DCs derive from the upstream tissue during homeostasis. Instead, our analysis suggests that nonlymphoid organ DCs comprise a major population of DCs within lymph nodes only after introduction of an inflammatory stimulus. PMID:18981237

    Full Text Available The moderate consumption of fish is recommended for a healthy diet and is also a feature of the Mediterranean diet. Fish is a major food group in diets throughout the world, and studies show that fish consumption is associated with a lower risk of a number of conditions. Spain has one of the highest annual per capita consumptions of fish worldwide. As fish is a source of high quality protein; n-3 polyunsaturated fatty acids; vitamins, such as A and D; and minerals, such as selenium, calcium, iodine, magnesium, copper and zinc, nutrients that have positive effects on bone characteristics, it has been proposed that its consumption could improve bone health. In this cross-sectional study, we have investigated the relationship between dietary habits and nutrient intake of 151 Spanish premenopausal women and analyzed the association of fish consumption on bone mass measured by quantitative ultrasound of the phalanges. A higher (P < 0.05 bone mass and vitamin D intake (P < 0.05 was observed in the group with a fish intake of 5–7 servings/week. We conclude that increased fish consumption is helpful in maintaining an adequate bone mass in Spanish premenopausal women.

    The purpose of this study was to examine the relationship between fasting serum leptin and adiponectin levels with bone mineral density (BMD) and body composition in pre-menopausal, middle-aged Hispanic and Caucasian women. Participants' (68 Hispanic and 36 Caucasian) BMD and bone mineral content were measured by dual-energy X-ray absorptiometry, and body density was measured by hydrodensitometry. Serum leptin was determined by enzyme immunoassay and adiponectin by ELISA. Hispanic women had significantly higher leptin, BMD, and fat mass (FM), and lower adiponectin than Caucasian women. There was no significant correlation between leptin and BMD for Hispanic or Caucasian women; adiponectin was inversely correlated with BMD in Caucasian women only (p = 0.01). In both Hispanic and Caucasian women, lean body mass and adiponectin best explained the variance in BMD (r(2) = 0.25, p < 0.001). These data demonstrate no significant relationship between leptin and BMD of pre-menopausal, middle-aged Hispanic and Caucasian women, and a significant inverse relationship between adiponectin and BMD in Caucasian women. The role of adipocytokines in the regulation of BMD remains inconclusive and may vary across ethnic groups.

    Full Text Available OBJECTIVES To evaluate whether saline contrast sonohysterography (SCSH improved the diagnostic accuracy of transvaginal sonography (TVS for predicting endometrial abnormality in premenopausal patients with abnormal uterine bleeding. PATIENTS AND METHODS The uterine cavity was evaluated with TVS and SCSH in 60 premenopausal patients with abnormal uterine bleeding. All 58 patients underwent operative hysteroscopy or hysterectomy within 4 months which provided a detailed description of the uterine cavity and was used as the true value for exclusion of polyps and submucous myomas. RESULT Out of 60 patients, 45 had uterine abnormalities on TVS and SCSH and rest of the patients who appeared normal but had other abnormalities such as ovarian haemorrhagic cyst. Out of the 45 patients, 9 patients had submucous myomas and 9 were diagnosed as endometrial polyp. The findings were confirmed using hysterectomy/hysteroscopy/endometrial sampling. CONCLUSION The use of TVS without saline contrast left nine submucosal fibroids and five in nine of the polyps undiagnosed in referred patients with complaints of abnormal bleeding. It also helps in reducing the rate of more invasive procedures such as hysteroscopy. However, studies carried out for longer duration and large study population are required to validate our findings

We collected reproductive and lifestyle factor information and measured anthropometrics and serum sex steroid concentrations among 314 premenopausal women living in Ulaanbaatar, Mongolia. Mean differences in hormone concentrations by these factors were calculated using age-adjusted quadratic regression splines. Estrone and estradiol in college-educated women were, respectively, 18.2% (p = 0.03 and 23.6% (p = 0.03 lower than in high-school-educated women. Progesterone concentrations appeared 55.8% lower (p = 0.10 in women residing in modern housing compared with women living in traditional housing (gers, although this finding was not statistically significant. Testosterone concentrations were positively associated with adiposity and central fat distribution; 17.1% difference (p = 0.001 for highest vs. lowest quarter for body mass index and 15.1% difference (p = 0.005 for waist-to-height ratio. Estrogens were higher in the follicular phase of women who breastfed each child for shorter durations. A distinct hormonal profile was associated with an urban lifestyle in premenopausal, Mongol women. In particular, heavier, more-educated women living in urban dwellings had higher testosterone and lower estrogen and progesterone levels. Higher breast cancer incidence in urban compared with rural women suggest that the hormonal profile associated with a more traditional lifestyle may be protective among Mongol women.

    We report a case of bilateral atypical femoral fractures that occurred in a patient who had been taking bisphosphonate long-term. A 36-year-old premenopausal female diagnosed with systemic lupus erythematosus and dermatomyositis had been treated with glucocorticoid and alendronate (5 mg/day) to prevent glucocorticoid-induced osteoporosis. She was taken to our hospital because she could not walk immediately after falling down from the standing position. A plain radiograph showed a subtrochanteric fracture of the left femur. Four months later, she fell again and sustained a contralateral subtrochanteric fracture. For each fracture, a femoral intramedullary nail was inserted. Delayed union was detected in both sides, and revision surgery with an iliac bone graft was required for implant breakage in the right side. Histomorphometric findings for the ilium revealed remarkably decreased osteoid volume with no osteoclasts and a minimally eroded surface, suggesting that bone turnover was severely suppressed. However, histology of the delayed union site revealed callus formation and some osteoclast appearance, suggesting that fracture healing was occurring. In total, it took 29 months (left) and 24 months (right) until fracture healing was achieved, showing delayed union. This case is extremely rare in that patient who presented with atypical femoral fractures in spite of her premenopausal status. The bone histomorphometric findings from this case suggest that severely suppressed bone turnover is associated with atypical femoral subtrochanteric fracture and can cause delayed union in patients treated with alendronate long-term.

Nineteen Mexican-American and 18 Korean premenopausal overweight/obese women were randomized into one of the following groups: control, low-intensity training group (LI), and high-intensity training group (HI). Subjects completed 12 weeks of training at 50-56% maximal oxygen consumption (LI) or 65-70% maximal oxygen consumption (HI). Body composition components were measured at baseline and after training using dual-energy X-ray absorptiometry for Mexican-Americans, while whole-body composition was measured by the direct segmental multifrequency bioelectrical impedance analysis and abdominal fat was measured by single-slice computed tomography for Koreans. Data were analyzed using mixed-model repeated measures independent of age, ethnicity, and body mass index (BMI). Exercise training showed a significant effect on BMI, fat percentage, fat mass, lean mass, and visceral adipose tissue area. HI significantly decreased fat mass and fat percentage but increased lean mass (all P fat mass, fat percentage, and visceral adipose tissue area but increased lean mass (all P fat percentage, fat mass, and visceral adipose tissue area but had no effect on increasing lean mass for Mexican-American and Korean premenopausal overweight/obese women.

    The sternal lymph nodes receive drainage from a wide variety of structures in the thoraco-abdominal region. Evaluation of these lymph nodes is essential, especially in cancer patients. Computed tomography (CT) can detect sternal lymph nodes more accurately than radiography or ultrasonography, and the criteria of the sternal lymphadenopathy are unknown. The purpose of this retrospective study was to describe the CT characteristics of the sternal lymph nodes in dogs considered unlikely to have lymphadenopathy. The ratio of the short axis dimension of the sternal lymph nodes to the thickness of the second sternebra was also investigated. At least one sternal lymph node was identified in each of the 152 dogs included in the study. The mean long axis and short axis dimensions were 0.700 cm and 0.368 cm, respectively. The mean ratio of the sternal lymph nodes to the second sternebrae was 0.457, and the 95% prediction interval ranged from 0.317 to 0.596 (almost a fixed value independent of body weight). These findings will be useful when evaluating sternal lymphadenopathy using CT.

    Full Text Available Introduction: The role and extent of extended pelvic lymph node dissection (ePLND during radical prostatectomy (RP for prostate cancer patients remains unclear. Materials and Methods: A PubMed literature search was performed for studies reporting on treatment regimens and outcomes in patients with prostate cancer treated by RP and extended lymph node dissection between 1999 and 2013. Results: Studies have shown that RP can improve progression-free and overall survival in patients with lymph node-positive prostate cancer. While this finding requires further validation, it does allow urologists to question the former treatment paradigm of aborting surgery when lymph node invasion from prostate cancer occurred, especially in patients with limited lymph node tumor infiltration. Studies show that intermediate- and high-risk patients should undergo ePLND up to the common iliac arteries in order to improve nodal staging. Conclusions: Evidence from the literature suggests that RP with ePLND improves survival in lymph node-positive prostate cancer. While studies have shown promising results, further improvements and understanding of the surgical technique and post-operative treatment are required to improve treatment for prostate cancer patients with lymph node involvement.

    Full Text Available Lymphonodular metastases remain an important predictive and prognostic factor in gastric cancer development. The precise determination of the lymphonodular invasion stage can be made only by extended intraoperative lymphadenectomy and histopathological examination. But the main controversy is the usefulness of extended lymph dissection in early gastric cancer. This increases the duration of the surgery and the complications rate, and it is unnecessary without lymphonodular invasion. The identification of the sentinel lymph nodes has been successfully applied for some time in the precise detection of lymph nodes status in breast cancer, malignant melanoma and the use for gastric cancer patients has been a controversial issue. The good prognosis in early gastric cancer had been a surgery challenge, which led to the establishment of minimally invasive individualized treatment and acceptance of sentinel lymph node mapping. The dual-tracer method, submucosally administered endoscopically is also recommended in sentinel lymph node biopsy by laparoscopic approach. There are new sophisticated technologies for detecting sentinel lymph node such as: infrared ray endoscopy, florescence imaging and near-infrared technology, carbon nanoparticles, which will open new perspectives in sentinel lymph nodes mapping.

    OBJECTIVE To evaluate the feasibility of intra-operative detection of sentinel lymph nodes (SLN) in the patient with endometrial cancer (EC).METHODS Thirty-one patients with Stage Ⅰ and Ⅱ endometrial cancer, who underwent a hysterectomy and a lymphadenectomy,were enrolled in the study. At laparotomy, methylene blue dye tracer was injected into the subserosal myometrium of corpus uteri at multiple sites, and dye uptake into the lymphatic channels was observed. The blue nodes which were identified as SLNs were traced and excised. The other nodes were then removed. All of the excised nodes were submitted for pathological hematoxylin and eosin (H&E) staining examination.RESULTS Failure of dye uptake occurred in 4 of the 31 cases (12.9%) because of spillage, and no lymphatic coloration was observed there. Lymphatic staining was clearly observable as blue dye diffused to the lymphatic channels of the uterine surface and the infundibulopelvic ligaments in 27 (87.1%) cases. Concurrent coloration in the pelvic lymphatic vessels was also observed in 22of the 27 patients. The SLNs were identified in 23 of the 27 (85.2%)cases with a lymphatic staining, with a total number of 90 SLNs,and a mean of 3.9 in each case (range, 1-10). Besides one SLN (1.1%)in the para-aortic area, the other 89 (98.9%) were in the nodes of the pelvis. The most dense locations of SLNs included obturator in 38 (42.2%) and interiliac in 19 (21.1%) cases. In our group, pelvic lymphadenectomy was conducted in 27 (87.1%) patients and pelvic nodal sampling in 4 (12.9%). Of the 31 cases, a concurrent abdominal para-aortic lymph node sampling was conducted in 7. A total of 926 nodes were harvested, with an average of 39.8 in each case (range, 14-55). Nodal metastases occurred in 3 patients (9.7%), 2 of them with SLN involvement and the other without SLN involvement. Adverse reactions or injury related to the study was not found.CONCLUSION Application of methylene blue dye is feasible in an intra

    Lymph node metastasis to the iliac or inguinal region of colon cancer is extremely rare. We experienced a case of ascending colon cancer with synchronous isolated right external iliac and inguinal lymph node metastases but without any regional lymph node metastasis. An 83-year-old woman was admitted to our hospital due to anemia. Colonoscopy and computed tomography revealed an ascending colon cancer and also right external iliac and inguinal lymph node swelling. Further examination by F-deoxyglucose positron emission tomography strongly suggested that these lymph nodes were metastatic. Right hemicolectomy with lymph node dissection along the superior mesenteric artery, and right external iliac and inguinal lymph node dissection were performed. Histological examination revealed that both lymph nodes were metastasized from colon cancer, and there was no evidence of regional lymph node metastasis. The patient has shown no sign of recurrence at 27 months after surgery.

    To judge the functional activity of lymphocytes of an implanted lymph node (LN), the proliferative response of lymphocytes of the implanted organ in the blast-transformation reaction in vitro and their ability to induce a local graft versus host reaction (GVHR) were determined. The lymphocyte suspension for labeling with /sup 51/Cr was obtained from peripheral LN in different situations from syngeneic mice. The resulting lymphocyte suspension was labeled with a solution of sodium chromate-/sup 51/Cr in a concentration of 20-40 microCi/100.10/sup 6/ cells in 1 ml for 40 min at 37/sup 0/C. The proliferative activity of a suspension of lymphocytes was estimated as incorporation of /sup 3/H-thymidine into DNA during incubation of the cell suspension for 3 days. Data on migration of /sup 51/Cr-labeled cells and the results of the morphological observations revealed marked ability of lymphocytes of the peripheral pool to colonize the regenerating stroma.

    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.

    Black women experience higher rates of hysterectomy than other women in the United States. Although research indicates that premenopausal hysterectomy with bilateral oophorectomy decreases the risk of breast cancer in black women, it remains unclear how hysterectomy without ovary removal affects risk, whether menopausal hormone therapy use attenuates inverse associations, and whether associations vary by cancer subtype. In the population-based, case-control Carolina Breast Cancer Study of invasive breast cancer in 1,391 black (725 cases, 666 controls) and 1,727 white (939 cases, 788 controls) women in North Carolina (1993-2001), we investigated the associations of premenopausal hysterectomy and oophorectomy with breast cancer risk. Compared with no history of premenopausal surgery, bilateral oophorectomy and hysterectomy without oophorectomy were associated with lower odds of breast cancer (for bilateral oophorectomy, multivariable-adjusted odds ratios = 0.60, 95% confidence interval: 0.47, 0.77; for hysterectomy without oophorectomy, multivariable-adjusted odds ratios = 0.68, 95% confidence interval: 0.55, 0.84). Estimates did not vary by race and were similar for hormone receptor-positive and hormone receptor-negative cancers. Use of estrogen-only menopausal hormone therapy did not attenuate the associations. Premenopausal hysterectomy, even without ovary removal, may reduce the long-term risk of hormone receptor-positive and hormone receptor-negative breast cancers. Varying rates of hysterectomy are a potentially important contributor to differences in breast cancer incidence among racial/ethnic groups.

    Full Text Available This study investigated whether Korean red ginseng (KRG extracts could improve sexual function in premenopausal women. Forty-one premenopausal women participated in this placebo-controlled, double-blind, and crossover clinical study with administration of either three ginseng capsules (1 g per capsule or placebo daily. After 8 weeks of medication of KRG or placebo, medication was changed for the subjects to placebo or KRG after 2 weeks of washout period. The efficacy of KRG extracts was measured by using Female Sexual Function Index (FSFI. Results. Twenty-three women completed the study. Total FSFI scores increased after KRG treatment (from 20.13±2.87 to 23.98±4.10, p=0.015 and placebo treatment (from 20.06±2.64 to 23.78±3.28, p=0.003. However, this change was not significantly different between the two groups (p=0.702. KRG treatment significantly improved sexual desire, arousal, orgasm, and satisfaction domains; however, there was no treatment effect compared with placebo. There was a case of gastric discomfort after taking KRG extracts. Oral administration of KRG extracts improved sexual function in premenopausal women; however, there were no statistical significant changes compared to placebo. It implies that KRG extracts have a substantial placebo effect in premenopausal women with sexual dysfunction.

    AIM: To study the localization of the solitary metastases in relation to the primary gastric cancers and the feasibility of sentinel lymph node (SLN) concept in gastric cancer.METHODS: Eighty-six patients with gastric cancer, who had only one lymph node involved, were regarded retrospectively as patients with a possible sentinel node metastasis, and the distribution of these nodes were assessed. Thirteen cases with jumping metastases were further studied and followed up.RESULTS: The single nodal metastasis was found in the nearest perigastric nodal area in 65.1% (56/86) of the cases and in 19.8% (17/86) of the cases in a fairly remote perigastric area. Out of 19 middle-third gastric cancers,3 tumors at the lesser or greater curvatures had transverse metastases. There were also 15.1% (13/86) of patients with a jumping metastasis to N2-N3 nodes without N1 involved. Among them, the depth of invasion was mucosal (M) in 1 patient, submucosal (SM) in 2, proper-muscular (MP) in 4, subserosal (SS) in 5, and serosa-exposed (SE)in 1. Five of these patients died of gastric cancer recurrence at the time of this report within 3 years after surgery.CONCLUSION: These results suggest that nodal metastases occur in a random and multidirectional process in gastric cancer and that not every first metastatic node is located in the perigastric region near the primary tumor.The rate of "jumping metastasis" in gastric cancer is much higher than expected, which suggests that the blind examination of the nodal area close to the primary tumor can not be a reliable method to detect the SLN and that a extended lymph node dissection (ELND) should be performed if the preoperative examination indicates submucosal invasion.

    Purpose To determine the impact of lymph node density (LND) on survival after inguinal lymph node dissection (ILND) for penile cancer. Materials and Methods Our institutional penile cancer database was queried for patients who underwent ILND. Clinicopathologic characteristics including LND and total number of positive lymph nodes (LNs) were analyzed to determine impact on recurrence-free survival (RFS) and overall survival (OS). LND, or the percent of positive LN out of total LN, was calculated as a categorical variable at varying thresholds. Results Twenty-eight patients with complete follow-up were identified. Indications for ILND were stage >T2 in 20 patients (71.4%), palpable adenopathy in 7 (25%), high grade T1 in 1 (3.6%). Median node yield was 17.5 (interquartile range, 12−22), and positive LNs were found in 14 patients (50%). RFS and OS were significantly lower for patients with >15% LN density (median RFS: 62 months vs. 6.3 months, p=0.0120; median OS: 73.6 months vs. 6.3 months, p15% was independently associated with worse RFS (hazard ratio [HR], 3.6; p=0.04) and OS (HR, 73.6; p=0.002). The c-index for LND was higher than total positive LNs for RFS (0.64 vs. 0.54) and OS (0.79 vs. 0.61). Conclusions In this small, retrospective penile cancer cohort, the presence of nodal involvement >15% was associated with decreased RFS and OS, and outperformed total number of positive LN as a prognostic indicator.

  4. Ultrasound elastography for evaluation of cervical lymph nodes

    2015-07-01

    Full Text Available Ultrasound (US elastography has been introduced as a noninvasive imaging technique for evaluating cervical lymph nodes. US elastography techniques include strain elastography and shear wave-based elastography. The application of this technique is based on the fact that stiff tissues tend to deform less and show less strain than compliant tissues when the same force is applied. In general, metastatic lymph nodes demonstrate higher stiffness than benign lymph nodes. Overall, preliminary studies suggest that US elastography may be useful in differentiating benign and malignant cervical lymph nodes, thereby informing decisions to perform a biopsy and facilitating follow-up. For US elastography to be accepted into clinical practice, however, its techniques, associated diagnostic criteria, and reliability need to be further refined.

    Full Text Available Background: Fine needle aspiration cytology as a first line of investigation has assumed importance in diagnosing a variety of disease process. The aim of this study was to assess the diagnostic value of fine needle aspiration cytology in the evaluation of palpable supraclavicular lymph nodes. Materials and methods: This was a retrospective study of fine needle aspiration cytology of palpable supraclavicular lymph node done between January 1, 2007 and December 31, 2009. Fine needle aspiration cytology was performed on 149 patients (49 cases at Om Hospital & Research Centre and 100 cases at Tribhuvan University Teaching Hospital. Results: The right supraclavicular lymph node was enlarged in 55% cases, while the left supraclavicular lymph node alone was palpable in 40.3% cases and in 7 of 149 (4.7% cases, bilateral supraclavicular lymph nodes were palpable. Cytological diagnoses were categorized as reactive (8.7%, tuberculosis (41.6%, lymphoma (4.8% and metastasis (44.9%. Of a total of 74 cases of malignancy, 90.5% were non-lymphoid and 9.5% were lymphoid (5 Non-Hodgkin lymphoma and 2 Hodgkin lymphoma. Of the 67 cases of metastatic disease, three major types of malignancy found in supraclavicular lymph nodes were Squamous cell carcinoma (28 cases, adenocarcinoma (21 cases and others (small cell carcinoma, papillary thyroid carcinoma etc. Adenocarcinoma tended to metastasize to the left supraclavicular lymph node. Lung was the most common primary site (43.3%, followed by stomach, ovary, breast and larynx. However, in 28.4% cases, no primary site was found. Conclusion: The fine needle aspiration cytology can be used as a first line investigation in the evaluation of supraclavicular lymphadenopathy due to its low cost, simplicity and minimal invasiveness.

    The optimal management of patients with pathologically node-negative triple-negative breast cancer (pN0 TNBC) remains unclear. We hypothesized that lymph node irradiation (LNI; internal mammary chain/periclavicular irradiation) had an impact on outcomes of pN0 TNBC. A cohort of 126 consecutive patients with pN0 TNBC treated between 2007 and 2010 at a single institute were included. All radiotherapy (breast/chest wall, ±LNI) was delivered adjuvantly, following completion of surgery ± chemotherapy. Tumors were reviewed and histologic features were described. Tissue microarrays were constructed and tumors were assessed by immunohistochemistry using antibodies against ER, PR, HER2, Ki-67, cytokeratins 5/6, 14, epidermal growth factor receptor and androgen receptor. Patients were divided into two groups for statistical analysis: LNI (LNI+) or no LNI (LNI-). We focused on disease-free survival (DFS), metastasis-free survival (MFS), and overall survival (OS). Fifty-seven and 69 patients received or not LNI, respectively. Median age was 52 (range [25-76]) and 55 (range [29-79]) in LNI+ and LNI- group (p = 0.23). LNI was associated with larger tumors (p = 0.033), central/internal tumors (33 versus 4, p 10 mm versus ≤10 mm), histologic size (pT >10 mm versus ≤10 mm) and grade 3 (versus grade 2) were found to be significantly associated with shorter DFS. Omission of LNI in patients with pN0 TNBC does not seem to result in poorer outcome. Further studies are needed to specifically evaluate LNI in pN0 TNBC with histologic grade 3 and/or (p)T >10 mm.

    Sentinel lymph node biopsy for melanoma was introduced in the early 1990s as a minimally invasive method of identifying and pathologically staging regional lymph node basins in patients with clinical stage I/II melanoma. Numerous large trials have demonstrated that sentinel lymph node evaluation has utility in improving accuracy of prognostication and for risk stratifying patients into appropriate groups for clinical trials. However, there remains a great deal of controversy regarding the therapeutic role of removal of the remainder of locoregional lymph nodes should metastatic cells be identified in the sentinel node. This CME article will outline a brief history of the sentinel node concept before reviewing updates in surgical technique, histopathologic evaluation of nodal tissue, and cost effectiveness of sentinel node biopsy. After completing this learning activity, participants should be able to describe the concept of sentinel lymph node biopsy, to discuss the risks and benefits associated with this procedure, and to summarize the role of sentinel lymph node biopsy in management of patients with melanoma.

    Sentinel lymph node biopsy (SLNB) has become the standard of care for early breast cancer. Its use in breast cancer has been evaluated in several randomized controlled trials and validated in multiple prospective studies. Additionally, it has been verified that SLNB has decreased morbidity when compared to axillary lymph node dissection (ALND). The technique used to perform sentinel lymph node mapping was also evaluated in multiple studies and the accuracy rate increases when radiocolloid and blue dye are used in combination. As SLNB became more accepted, contraindications were delineated and are still debated. Patients who have clinically positive lymph nodes or core biopsy-proven positive lymph nodes should not have SLNB, but should have an ALND as their staging procedure. The safety of SLNB in pregnant patients is not fully established. However, patients with multifocal or multicentric breast cancer and patients having neoadjuvant chemotherapy are considered candidates for SLNB. However, the details of which specific neoadjuvant patients should have SLNB are currently being evaluated in a randomized controlled trial. Patients with ductal carcinoma in situ (DCIS) benefit from SLNB when mastectomy is planned and when there is a high clinical suspicion of invasion. With the advent of SLNB, pathologic review of breast cancer lymph nodes has evolved. The significance of occult metastasis in SLNB patients is currently being debated. Additionally, the most controversial subject with regards to SLNB is determining which patients with positive SLNs benefit from further axillary dissection.

    Morbidity and complexity involved in lymph node staging via surgical resection and biopsy calls for staging techniques that are less invasive. While visible blue dyes are commonly used in locating sentinel lymph nodes, since they follow tumor-draining lymphatic vessels, they do not provide a metric to evaluate presence of cancer. An area of active research is to use fluorescent dyes to assess tumor burden of sentinel and secondary lymph nodes. The goal of this work was to successfully deploy and test an intra-nodal cancer-cell injection model to enable planar fluorescence imaging of a clinically relevant blue dye, specifically methylene blue along with a cancer targeting tracer, Affibody labeled with IRDYE800CW and subsequently segregate tumor-bearing from normal lymph nodes. This direct-injection based tumor model was employed in athymic rats (6 normal, 4 controls, 6 cancer-bearing), where luciferase-expressing breast cancer cells were injected into axillary lymph nodes. Tumor presence in nodes was confirmed by bioluminescence imaging before and after fluorescence imaging. Lymphatic uptake from the injection site (intradermal on forepaw) to lymph node was imaged at approximately 2 frames/minute. Large variability was observed within each cohort.

    The majority of ovarian cancer recurrences are in the abdomen. However, some cases relapse as isolated lymph node metastases, mostly in pelvic or para-aortic nodes. Peripheral isolated lymph node metastasis is rare. A 69-year-old Japanese woman had recurrent ovarian cancer presenting with isolated right supraclavicular lymph node metastasis. After surgical resection and combination chemotherapy with carboplatin and paclitaxel, her right supraclavicular lymph node completely regressed. Peripheral isolated lymph nodes, including right supraclavicular lymph node, can recur without a macroscopic abdominal lesion. Clinicians should carefully examine peripheral lymph nodes for recurrence.

    Myofibroblastoma of the breast (MFB) is a rare benign tumor of mesenchymal origin with only 80 cases reported in the literature so far. It most commonly occurs in elderly males and postmenopausal females and grows slowly over a period of months to years. In this study we describe a very rare case of a MFB in a premenopausal woman who presented with a rapidly growing breast mass. Diagnostic evaluation and management of the patient are discussed along with a review of the literature. We conclude that despite its rarity, myofibroblastoma should always be considered in the differential diagnosis of mesenchymal breast tumors. No specific imaging features have been described. Thorough immunohistochemical analysis is crucial to obtain a definitive diagnosis. Local excision is the treatment of choice.

    We treated randomly 75 premenopausal patients with advanced breast cancer with combination chemotherapy (5-fluorouracil, cyclophosphamide and prednisone), either as an early adjunct to oophorectomy or as a delayed treatment upon appearance of progressive metastatic disease after operation. The group receiving early systemic chemotherapy enjoyed an improved response rate, an improved survival rate and, most importantly, an improved progression-free interval (median of 53 versus 17 weeks). With the exclusion of the group with early (within three weeks after oophorectomy) progression, the progression-free intervals had a median duration of 77 weeks in the early-treatment group versus 33 weeks in the control group. The early-progression group did exceedingly poorly, although systemic chemotherapy was employed at that juncture, having a median survival of 22 weeks as compared to 144 weeks in the immediate-treatment group and 105 weeks in the control group.

    The purpose was to evaluate the relationships between fasting serum leptin, resting metabolic rate (RMR), and body composition in premenopausal Hispanic and non-Hispanic White (White) women. Participants were 67 Hispanic and 43 White women who arrived at the laboratory in a fasted state for measurement of RMR by indirect calorimetry, bone mineral content measured by dual-energy X-ray absorptiometry, and body density measured by hydrodensitometry. Serum leptin levels were determined by EIA. Multiple regression analysis revealed that body mass and lean body mass were the best predictors of RMR. Leptin was not a significant predictor of RMR. Further research needs to be done to examine the role of leptin on metabolism, especially in ethnic groups predisposed to development of obesity and related disorders.

    Background. Serotonin and brain-derived neurotrophic factor (BDNF) are known to be modulators of nociception. However, pain-related connection between yoga and those neuromodulators has not been investigated. Therefore, we aimed to evaluate the effect of yoga on pain, BDNF, and serotonin. Methods. Premenopausal women with chronic low back pain practiced yoga three times a week for 12 weeks. At baseline and after 12 weeks, back pain intensity was measured using visual analogue scale (VAS), and serum BDNF and serotonin levels were evaluated. Additionally, back flexibility and level of depression were assessed. Results. After 12-week yoga, VAS decreased in the yoga group (P yoga group (P yoga group (P yoga group, while it reduced (P yoga group, whereas it tended to increase in the control group (P = 0.07). Conclusions. We propose that BDNF may be one of the key factors mediating beneficial effects of yoga on chronic low back pain.

    Few studies have established the lifestyle predictors of peak bone mineral density (BMD) in Mexican-American (MA) and Asian-American (AA) women. Pre-menopausal MA (n = 48) and AA (n = 58) women aged 30-45 years old were tested for BMD, body composition, aerobic fitness, and muscle function. Socio-demographic characteristics, health status, prevalence of osteoporosis risk factors, physical activity, and diet were determined via questionnaire. Pearson's correlations and multiple linear regressions were used to test the associations between various osteoporosis risk factors and BMD. Body composition, anthropometric, and BMD differences were noted between groups. Hip, but not spine BMD, remained significantly higher for the MA compared to the AA group after adjustment for age, BMI, income, and physical activity index. Lean body mass was a significant predictor of hip BMD for both groups and this relationship was stronger for the AA group. Lean body mass may explain ethnic differences in BMD.

    Twenty-four-hour energy expenditure and substrate use were measured by indirect calorimetry in respiration chambers on a fixed physical program and related to body composition and plasma concentrations of various substrates and thermogenic hormones. Fifty premenopausal women with a wide range...... of body weight were examined in the follicular menstrual phase under weight stable conditions. Most of the variance in the sleeping energy expenditure (82%) was accounted for by two covariates, lean body mass (75%, P less than 0.0001), and fat mass (7%, P less than 0.0001). An additional 6...... circumference, plasma nonesterified fatty acids, and estradiol concentrations explained 49% of the variance in 24-h lipid oxidation. An obese subgroup of women (n = 27) had significantly higher 24-h energy expenditure, lipid, and carbohydrate oxidation rates than an age-matched normal weight group (n = 16...

    BACKGROUND: Hormonal fluctuations during the menstrual cycle influence energy intake and expenditure as well as eating preferences and behavior. OBJECTIVE: We examined the impact of a diet and exercise weight-loss program that was designed to target and moderate the effects of the menstrual cycle...... compared with the effect of simple energy restriction. DESIGN: A total of 60 healthy, overweight, premenopausal women were included in a 6-mo weight-loss program in which each subject consumed a diet of 1600 kcal/d. Subjects were randomly assigned to either a combined diet and exercise program....... CONCLUSION: A differentiated diet and exercise program that is tailored to counteract food cravings and metabolic changes throughout the menstrual cycle may increase weight loss above that achieved with a traditional diet and exercise program in women who can comply with the program.

    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.

    Chemotherapy-induced amenorrhea (CIA) is a side effect that occurs in patients with breast cancer (BC) as a result of chemotherapy. These patients require special treatments to avoid infertility and menopause. However, the factors controlling CIA, resumption of menstruation (RM), and persistence of menstruation after chemotherapy are unknown. The long-term prognosis for premenopausal patients with BC and the prognostic factors associated with CIA and RM are subject to debate. We performed a retrospective study by reviewing the medical records of 249 patients with BC (stage I to stage III) who were treated with cytotoxic chemotherapy. The median patient age was 43 (range, 26-55 years) and the median duration of follow-up was 64 months (range, 28-100 months). The medical records indicated that 219 patients (88.0%) scored as positive for the hormone receptor (HR); the majority of these patients completed chemotherapy and then received additional therapy of tamoxifen. Our analyses revealed that 88.0% (n = 219) of patients experienced CIA, and the percentage of RM during follow-up was 48.6% (n = 121). A total of 30 patients (12.0%) did not experience CIA. Disease-free survival (DFS) was affected by several factors, including tumour size ≥2 cm, node positivity, HR negative status, and body mass index ≥23 kg/m. Multivariate analysis indicated that tumour size ≥2 cm remained as a significant factor for DFS (hazard ratio = 3.3, P = 0.034). In summary, this study finds that the majority of premenopausal patients with BC (stage I to stage III) who receive chemotherapy experience CIA and subsequent RM. Although tumour size ≥2 cm is negatively associated with DFS, RM after CIA is not associated with poor prognosis.

    This study aimed to investigate whether pre-chemotherapy anti-mullerian hormone (AMH) is a biomarker for chemotherapy-related amenorrhea (CRA) in breast cancer patients. A multicenter randomized controlled trial, ECOG5103, assigned patients with early stage breast cancer to standard doxorubicin-cyclophosphamide followed by paclitaxel with either placebo or one of two durations of bevacizumab therapy. Five hundred ninety-one patients were part of the decision-making/quality of life substudy, in which there were surveys from baseline through 18-month follow-up. One hundred twenty-four women were included in this analysis of menses data because they were premenopausal at enrollment, responded to the 12-month survey, had not undergone bilateral oophorectomy or ovarian function suppression before that survey, and had serum banked for research before chemotherapy. One hundred of the 124 also responded to the 18-month survey. Median age was 45 years (range 25-55), and median serum AMH level was 0.11 ng/mL (range 0.01-8.63) prior to treatment. Eighty-two percent had CRA at 12 months, and 81 % at 18 months. In multivariate analyses, older age (p = 0.0003) was the only statistically significant predictor of 12-month CRA, but at 18-months, lower pre-chemotherapy AMH (p = 0.04) and older age (p = 0.008) were both statistically significant predictors of CRA. Race, bevacizumab therapy, and tamoxifen use were not statistically significantly associated with CRA after adjustment for AMH and age. Pre-chemotherapy AMH level is a potential novel biomarker for CRA in premenopausal women with early stage breast cancer. Further research to evaluate the clinical utility of AMH testing is warranted.

    Higher circulating prolactin levels have been associated with higher percent mammographic density among postmenopausal women in some, but not all studies. However, few studies have examined associations with dense area and non-dense breast area breast or considered associations with prolactin Nb2 lymphoma cell bioassay levels. We conducted a cross-sectional study among 1,124 premenopausal and 890 postmenopausal women who were controls in breast cancer case-control studies nested in the Nurses' Health Study (NHS) and NHSII. Participants provided blood samples in 1989-1990 (NHS) or 1996-1999 (NHSII) and mammograms were obtained from around the time of blood draw. Multivariable linear models were used to assess the associations between prolactin levels (measured by immunoassay or bioassay) with percent density, dense area, and non-dense area. Among 1,124 premenopausal women, percent density, dense area, and non-dense area were not associated with prolactin immunoassay levels in multivariable models (p trends = 0.10, 0.18, and 0.69, respectively). Among 890 postmenopausal women, those with prolactin immunoassay levels in the highest versus lowest quartile had modestly, though significantly, higher percent density (difference = 3.01 percentage points, 95 % CI 0.22, 5.80) as well as lower non-dense area (p trend = 0.02). Among women with both immunoassay and bioassay levels, there were no consistent differences in the associations with percent density between bioassay and immunoassay levels. Postmenopausal women with prolactin immunoassay levels in the highest quartile had significantly higher percent density as well as lower non-dense area compared to those in the lowest quartile. Future studies should examine the underlying biologic mechanisms, particularly for non-dense area.

    Full Text Available Abstract Background Both obesity and type 2 diabetes are among the risk factors for breast cancer development. Combined effect of these metabolic abnormalities on breast cancer risk however, has not been examined in premenopausal women. We tested this association in type 2 diabetic women, categorized as obese, overweight and normal body weight groups based on BMI. Design and methods A total of 101 subjects were included in this study. Serum levels of IL-6, TNF-α, C reactive protein, leptin, TGF-α, adiponectin and insulin were measured by ELISA. Data were logarithmically transformed for variables not normally distributed. Analysis of variance with post-hoc Bonferroni was applied to compare the data between the groups. Simple and partial correlation coefficients between the variables were determined and a stepwise multiple linear regression analysis was performed to determine the relationships between the variables of interest. Results Significantly increased levels of IL-6, C reactive protein, leptin and significantly decreased levels of adiponectin were found in obese group, while the levels of TNF-α and TGF-α were unaltered. A positive correlation between waist circumference and IL-6 was found in obese group. Similarly, C reactive protein, waist and hip circumferences were linearly correlated with BMI in obese group. Stepwise multiple linear regression analysis revealed several significant predictors for breast cancer risk. Conclusion Obesity and type 2 diabetes, owing to their effects on adipocytokines and inflammatory mediators, contribute to increased breast cancer risk in premenopausal women. This study emphasizes healthy life style and better management of these metabolic disorders to avoid the pathogenesis of breast cancer and of other chronic diseases.

    A 28-week resistance training with linear periodization was compared with an undulating model in 27 premenopausal women. In both groups, bone mineral density (BMD) was not changed but muscle strength increased, and there were changes in anthropometrical and muscle damage parameters, indicating that in this population, these models are similar concerning these variables. This study seeks to compare the effects of resistance training with undulating versus linear periodization on BMD, muscle strength, anthropometrical variables, and muscle damage parameters in premenopausal women. Twenty-seven females (39.6 +/- 0.41 years, mean +/- standard error), without osteopenia or osteoporosis and without calcium supplementation, were randomly assigned either to a linear periodization group (LPG, n = 14) or to an undulating periodization group (UPG, n = 13). The subjects were trained three times a week for 28 weeks. Lumbar spine and femoral neck BMDs were measured through dual-energy X-ray absorptiometry. Maximal and submaximal dynamic muscle strengths were measured through the 1-RM and 20-RM tests, respectively. Anthropometrical (body mass, skinfolds, and perimeters) and muscle damage parameters were assessed through serum creatine kinase (CK) and delayed-onset muscle soreness (DOMS). BMD remained unchanged in both groups, despite significant increases in maximal (LPG, 37-73%; UPG, 40-70%) and submaximal (LPG, 82-114%; UPG, 70-102%) muscle strength. The perimeter of the distal thigh was increased (about 1.7 cm) in both groups. CK and DOMS were greater in the first mesocycle than in the subsequent ones. After the 1st training session in each mesocycle, 24 and 48 h CK was increased as compared to pretraining values. The resistance training of 28 weeks increased muscle strength in both training groups with no difference in BMD or in the occurrence of muscle damage.

    Soya foods may protect against the development of breast cancer. Insulin-like growth factor (IGF)-1 is under investigation as a possible link between nutrition and cancer. We examined the effect of soya foods on circulating IGF-1 and IGF binding protein (BP)-3 levels among 196 healthy premenopausal women in a 2-year randomised nutritional trial. The intervention group consumed two daily servings of soya foods including tofu, soya milk, soya nuts and soya protein powder (equivalent to 50 mg isoflavones and 5-22 g soya protein per serving); the controls maintained their regular diet. Five serum samples at baseline, 3, 6, 12, and 24 months were collected in the morning during the luteal phase and analysed for IGF-1 and IGFBP-3 by double-antibody ELISA. We applied mixed models to investigate the intervention effect and predictors of serum levels while considering the repeated measurement design. Adherence with the study regimen was high and dropout rates were acceptable. Randomisation resulted in similar mean IGF-1 and IGFBP-3 levels by group. We did not observe a significant intervention effect on IGF-1, IGFBP-3, and their molar ratio during the entire study period. However, urinary isoflavone excretion during the study period was positively associated with IGF-1 (P=0.04) and the IGF-1:IGFBP-3 ratio (P=0.06). The effect was consistent over time. Adding soya foods to the diet of premenopausal women does not appear to lower serum levels of IGF-1 and IGFBP-3; if anything, the greater protein intake from soya may lead to a small increase in IGF-1 serum levels.

    Tamoxifen and fenretinide have been extensively studied and exhibit breast cancer-preventing activity. We aimed to assess their effect on sex hormones, sex hormone binding globulin (SHBG) and retinol, and their association with mammographic density (MD) and breast cancer events. In a double-blind, placebo-controlled trial, premenopausal women at risk for breast cancer were randomized to tamoxifen 5 mg/day, fenretinide, both agents, or placebo for 2 years. We measured MD and circulating concentrations of follicle-stimulating hormone, luteinizing hormone (LH), estradiol, progesterone, testosterone, androstenedione, dehydro-epiandrosteronesulfate, prolactin, SHBG, and retinol at baseline and on yearly intervals. The associations with breast cancer events were evaluated through competing risk and Cox regression survival models. Low-dose tamoxifen markedly and enduringly increased SHBG, whereas the increases in testosterone, estradiol, and prolactin and reduction in LH weakened after 1 year. Fenretinide increased testosterone and androstenedione and decreased retinol. MD correlated directly with SHBG and inversely with retinol. After a median follow-up of 12 years, the 10-year cumulative incidence of breast cancer events was 37 % in women with SHBG ≤ 59.3 nmol/L, 22 % in women with SHBG between 59.3 and 101 nmol/L, and 19 % in women with SHBG > 101 nmol/L (P = 0.018). The difference among SHBG tertiles remained statistically significant at multivariable analysis: HR = 2.26 (95 % CI 1.04, 4.89) for the lowest versus the highest tertile. We conclude that low-dose tamoxifen or fenretinide exhibits favorable hormonal profiles as single agents, further supporting their administration for prevention of breast cancer in premenopause. Notably, SHBG levels were inversely associated with breast neoplastic events.

    Mammographic density is strongly associated with breast cancer risk, and endogenous hormones, which are risk factors for breast cancer, may be involved in the mechanism. This cross-sectional study of 494 premenopausal women is the first to account for cyclic variations in estrogen levels, by measuring urinary estrone glucuronide (E1G) in the periovulatory and luteal phases of the menstrual cycle, and to assess the role of androgens. Computer-assisted density readings were obtained from digitized mammograms. Mean ovulatory E1G level and daily E1G load were both positively associated with percent density before adjustment for body mass index (BMI), with women in the top fourth having 10.2% (95% CI: 2.9%, 18.1%) and 8.9% (1.7%, 16.7%), respectively, higher density than those in the bottom fourth (Ptrend before/after BMI adjustment=0.006/0.11 and 0.01/0.13, respectively). Neither the peak nor luteal E1G levels were predictive of density after adjustment for E1G levels at other points in the cycle. The plasma androgens testosterone, androstenedione, and dehydroepiandrosterone sulfate were negatively associated with density. In mutually adjusted analyses, density was positively associated with insulin-like growth factor (IGF)-I and negatively with IGF-II (Ptrend=0.006 for both) but not with IGF binding protein-3. There was also weak evidence of a positive association of prolactin with density. The study supports the hypothesis that endogenous hormones affect density in premenopausal women; in particular, it shows a positive association between estrogen levels and density and suggests that the mean level throughout the cycle is the most biologically relevant measure. Most of these hormone-density associations were attenuated with further adjustment for BMI.

    The frequency and proliferative activity of tissue-specific stem and progenitor cells are suggested to correlate with cancer risk. In this study, we investigated the association between breast cancer risk and the frequency of mammary epithelial cells expressing p27, estrogen receptor (ER), and Ki67 in normal breast tissue. We performed a nested case-control study of 302 women (69 breast cancer cases, 233 controls) who had been initially diagnosed with benign breast disease according to the Nurses' Health Studies. Immunofluorescence for p27, ER, and Ki67 was performed on tissue microarrays constructed from benign biopsies containing normal mammary epithelium and scored by computational image analysis. We found that the frequency of Ki67(+) cells was positively associated with breast cancer risk among premenopausal women [OR = 10.1, 95% confidence interval (CI) = 2.12-48.0]. Conversely, the frequency of ER(+) or p27(+) cells was inversely, but not significantly, associated with subsequent breast cancer risk (ER(+): OR = 0.70, 95% CI, 0.33-1.50; p27(+): OR = 0.89, 95% CI, 0.45-1.75). Notably, high Ki67(+)/low p27(+) and high Ki67(+)/low ER(+) cell frequencies were significantly associated with a 5-fold higher risk of breast cancer compared with low Ki67(+)/low p27(+) and low Ki67(+)/low ER(+) cell frequencies, respectively, among premenopausal women (Ki67(hi)/p27(lo): OR = 5.08, 95% CI, 1.43-18.1; Ki67(hi)/ER(lo): OR = 4.68, 95% CI, 1.63-13.5). Taken together, our data suggest that the fraction of actively cycling cells in normal breast tissue may represent a marker for breast cancer risk assessment, which may therefore impact the frequency of screening procedures in at-risk women.

    Full Text Available Iron and zinc are essential minerals often present in similar food sources. In addition to the adverse effects of frank iron and zinc-deficient states, iron insufficiency has been associated with impairments in mood and cognition. This paper reviews current literature on iron or zinc supplementation and its impact on mood or cognition in pre-menopausal women. Searches included MEDLINE complete, Excerpta Medica Database (EMBASE, psychINFO, psychARTICLES, pubMED, ProQuest Health and Medical Complete Academic Search complete, Scopus and ScienceDirect. Ten randomized controlled trials and one non-randomized controlled trial were found to meet the inclusion criteria. Seven studies found improvements in aspects of mood and cognition after iron supplementation. Iron supplementation appeared to improve memory and intellectual ability in participants aged between 12 and 55 years in seven studies, regardless of whether the participant was initially iron insufficient or iron-deficient with anaemia. The review also found three controlled studies providing evidence to suggest a role for zinc supplementation as a treatment for depressive symptoms, as both an adjunct to traditional antidepressant therapy for individuals with a diagnosis of major depressive disorder and as a therapy in its own right in pre-menopausal women with zinc deficiency. Overall, the current literature indicates a positive effect of improving zinc status on enhanced cognitive and emotional functioning. However, further study involving well-designed randomized controlled trials is needed to identify the impact of improving iron and zinc status on mood and cognition.

    Objective To explore the relationship between D2-40 and CCR7 expression and lymph node metastasis in Non-small cell lung cancer. Methods D2-40 and CCR7 expression in 104 non-small cell lung cancer patients, 10 cases of with tissues adjacent to non-small cell lung cancer, and 5 normal lung tissues is identified by MAX Vision, an immunohistochemical staining technique. The lymphatic endothelial cells are meanwhile marked by D2-40 for MLVD calculation. Results The MLVD counts are strongly increased in the non-small cell lung cancers compared with those in normal lung tissues ( 7. 81 ± 2. 22 vs. 4. 20 ± 1.07, P<0. 001 ). The MLVD counts of the 47 cases with lymph node positive also are higher than those of the 57 cases with lymph node negative (8. 39 ± 2. 35>7. 33 ± 2. 00, P<0. 001). CCR7 positive rate is 82. 7% (86/104) in the 104 cases of non-small cell lung cancers, 30% (3/10) in the 10 cases of pericancerous tissues, and 20% (1/5) in the 5 cases of normal lung tissues. The ratio of CCR7 in lymph nodes positive is more increased than that lymph nodes negative (87. 2% vs 61.4%, x2 = 87. 4, P <0. 05 ). The MLVD count of CCR7 of the positive group is(8. 51 ± 2. 03), higher than that of the CCR7 of the negative group(6. 01 ± 1.59)(P<0. 05). The expression of the MLVD marked by D)2-40 is positively correlated to the CCR7 in the non-small cell lung cancers (coefficient of correlation, r= 0. 597,P<0. 000). Conclusion In non-small cell lung cancers, the increased expression of CCR7 in the lymph node metastasis positive group is positively related to the MLVD marked by D2-40. D2-40 staining is observed only in the lymphatic endothelial cells, while the increased expression of CCR7 in cancer cells is an early event of lymph node metastases. The combination of CCR7 and D2-40 measurement is likely to predict lymphatic metastases.%目的 探讨CCR7及D2-40在非小细胞肺癌中的表达与淋巴结转移的关系.方法 采

    We report a case with lymph node metastasis of osteosarcoma, which is a rare entity in comparison to hematogeneous lung or bone metastasis. Twenty-seven years old male patient referred to our clinic complaining of ongoing left knee pain and swelling since one month without a history of prior trauma. Magnetic resonance imaging (MRI) revealed a mass of malignant nature which causes more prominent expansion and destruction of the bone distally with periosteal reaction. A lymphadenomegaly 16mm×13mm in diameter was also present in the popliteal fossa having the same signal pattern with the primary lesion. Thirteen weeks following the first referral of the patient, wide resection and reconstruction with modular tumor prosthesis was performed. Popliteal lymph node was excised through the same incision. Pathologic examination of the resected speciman reported osteoblastic osteosarcoma. The lymph node extirpated from the popliteal fossa was reported to be a metastasis of the primary tumor. Osteosarcoma of the long bones is the most common primary malignant bone neoplasm of both childhood and adulthood. Osteosarcomas commonly metastasize hematogeneously to the lungs and bones. Lymph node metastasis is a rare entity. Similar studies report rates between 2.3% and 4%. It is not clearly explained, how lymph node metastasis in osteosarcoma occurs despite lack of lymphatic drainage in normal cortical and spongious bone. Lymph node metastasis of osteosarcoma is a rare entity and metastatic patterns could not be clearly explained. On the other hand, the effects of lymph node metastasis on prognosis are also not clearly defined and further studies are needed. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    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

    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.

    Full Text Available Abstract Background Various biomarkers for prediction of distant metastasis in lymph-node negative breast cancer have been described; however, predictive biomarkers for patients with lymph-node positive (LNP disease in the context of distinct systemic therapies are still very much needed. DNA methylation is aberrant in breast cancer and is likely to play a major role in disease progression. In this study, the DNA methylation status of 202 candidate loci was screened to identify those loci that may predict outcome in LNP/estrogen receptor-positive (ER+ breast cancer patients with adjuvant anthracycline-based chemotherapy. Methods Quantitative bisulfite sequencing was used to analyze DNA methylation biomarker candidates in a retrospective cohort of 162 LNP/ER+ breast cancer patients, who received adjuvant anthracycline-based chemotherapy. First, twelve breast cancer specimens were analyzed for all 202 candidate loci to exclude genes that showed no differential methylation. To identify genes that predict distant metastasis, the remaining loci were analyzed in 84 selected cases, including the 12 initial ones. Significant loci were analyzed in the remaining 78 independent cases. Metastasis-free survival analysis was conducted by using Cox regression, time-dependent ROC analysis, and the Kaplan-Meier method. Pairwise multivariate regression analysis was performed by linear Cox Proportional Hazard models, testing the association between methylation scores and clinical parameters with respect to metastasis-free survival. Results Of the 202 loci analysed, 37 showed some indication of differential DNA methylation among the initial 12 patient samples tested. Of those, 6 loci were associated with outcome in the initial cohort (n = 84, log rank test, p Promoter DNA methylation of cysteine dioxygenase 1 (CDO1 was confirmed in univariate and in pairwise multivariate analysis adjusting for age at surgery, pathological T stage, progesterone receptor status

    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...

    To investigate the coverage of axillary lymph node with tangential breast irradiation fields by using virtual lymph node (LN) analysis. Forty-eight women who were treated with whole breast irradiation after breast-conserving surgery were analyzed. The axillary and breast volumes were delineated according to the Radiation Therapy Oncology Group (RTOG) contouring atlas. To generate virtual LN contours, preoperative fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) scans with identifiable LN were fused with the CT scans, and the virtual LN contour were delineated on the CT. The median level I and II axillary volume coverage percentages at the VD95% line were 33.5% (range, 5.3% to 90.4%) and 0.6% (range, 0.0% to 14.6%), respectively. Thirty-one LNs in 18 patients were delineated (26 in level I and 5 in level II). In the level I axilla, 84.6% of virtual LNs were encompassed by the 95% isodose line. In the level II axilla, by contrast, none of the virtual LNs were encompassed by the 95% isodose volumes. There was a substantial discrepancy between the RTOG contouring atlas-based axillary volume analysis and the virtual LN analysis, especially for the level I axillary coverage. The axillary volume coverage was associated with the body mass index (BMI) and breast volume. The tangential breast irradiation did not deliver adequate therapeutic doses to the axillary region, particularly those in the level II axilla. Patients with small breast volumes or lower BMI showed reduced axillary coverage from the tangential breast fields. For axillary LN irradiation, individualized anatomy-based radiation fields for patients would be necessary.

    Lymph nodes are assessed routinely in clinical practice and their size is followed throughout radiation or chemotherapy to monitor the effectiveness of cancer treatment. This paper presents a robust learning-based method for automatic detection and segmentation of solid lymph nodes from CT data, with the following contributions. First, it presents a learning based approach to solid lymph node detection that relies on marginal space learning to achieve great speedup with virtually no loss in accuracy. Second, it presents a computationally efficient segmentation method for solid lymph nodes (LN). Third, it introduces two new sets of features that are effective for LN detection, one that self-aligns to high gradients and another set obtained from the segmentation result. The method is evaluated for axillary LN detection on 131 volumes containing 371 LN, yielding a 83.0% detection rate with 1.0 false positive per volume. It is further evaluated for pelvic and abdominal LN detection on 54 volumes containing 569 LN, yielding a 80.0% detection rate with 3.2 false positives per volume. The running time is 5-20 s per volume for axillary areas and 15-40 s for pelvic. An added benefit of the method is the capability to detect and segment conglomerated lymph nodes.

    Toxic factors released from the intestine have been implicated in the pathophysiology of severe acute illness, including acute pancreatitis, trauma and hemorrhagic shock, and burns. Toxic factors in mesenteric lymph may induce an inflammatory systemic response while bypassing the portal circulation and liver. This paper reviews current knowledge of the anatomy, physiology and pathophysiology of mesenteric lymph and focuses on factors influencing its composition and flow, and potential therapeutic interventions. A search of the Ovid MEDLINE database up until the end of January 2006 yielded 1,761 relevant publications, the references of which were then searched manually to identify further related publications. A wide range of factors potentially affecting mesenteric lymph flow and composition were identified. Targeted interventions have been similarly broad, including medical therapy, nutritional support and surgery. Of the available surgical interventions, thoracic duct external drainage has been the most widely studied. This systematic review highlights significant gaps in our present understanding of the role of mesenteric lymph in health and disease. Further research is needed to identify factors responsible for the generation of biologically active mesenteric lymph, the role of agents modulating its flow and composition, the importance of intrinsic pump activity, the potential therapeutic role of lipophilic antioxidant agents, the comparative effects of low-fat enteral nutrition and standard enteral nutrition, and the therapeutic outcomes of thoracic duct ligation versus thoracic duct external drainage.

    Full Text Available Abstract Background The efficiency of lymph nodes depends on tissue structure and organization, which allow the coordination of lymphocyte traffic. Despite their essential role, our understanding of lymph node specific mechanisms is still incomplete and currently a topic of intense research. Results In this paper, we present a hybrid discrete/continuous model of the lymph node, accounting for differences in cell velocity and chemotactic response, influenced by the spatial compartmentalization of the lymph node and the regulation of cells migration, encounter, and antigen presentation during the inflammation process. Conclusion Our model reproduces the correct timing of an immune response, including the observed time delay between duplication of T helper cells and duplication of B cells in response to antigen exposure. Furthermore, we investigate the consequences of the absence of dendritic cells at different times during infection, and the dependence of system dynamics on the regulation of lymphocyte exit from lymph nodes. In both cases, the model predicts the emergence of an impaired immune response, i.e., the response is significantly reduced in magnitude. Dendritic cell removal is also shown to delay the response time with respect to normal conditions.

    Full Text Available Hemangioma is a benign tumor of blood and lymphatic vessels. It is common in skin, mucosa and soft tissues, and its occurrence in lymph nodes is extremely rare. A 10 year-old she-camel was slaughtered at Nyala slaughterhouse, South Darfur State, Sudan. Grossly, the carcass was emaciated. The left ventral superficial cervical lymph node was enlarged, hard on palpation and protruded outside the body. Its cut surface was dark red in color and measured (18 cm in diameter. Histopathologically, the sections revealed vascular masses were composed of non-encapsulated clusters of small and medium sized with thick and thin-walled, filled with blood, separated by courageous stroma and surrounded by closely packed proliferating capillaries. To the best of our knowledge, this is the first record of the left ventral superficial cervical lymph node hemangioma in a camel in the Sudan.

    2015-01-01

    Objective:Lymphadenectomy has been increasingly regarded as standard surgical procedure for advanced gastric cancer (GC), while necessity No.14v lymph node dissection for lower GC is still controversial.Methods: A total of 311 GC patients receiving D1+ (D1+7, 8a, 9) or D2 plus No.14v lymph node dissection in our center were enrolled. Patients were categorized into two groups based on No.14v lymph node status: positive group (PG) and negative group (NG).Results:Fifty patients (16.1%) had No.14v lymph node metastasis. Metastasis to No.4d, No.6 lymph node and distant metastasis were independent variables affecting No.14v lymph node metastasis. Patients with positive No.14v lymph node had a significant lower overall survival (OS) rate than those without (3-year OS, 34.0% vs. 67.0%,P<0.001).Conclusion:GC patients with positive No.4d and No.6 lymph node often metastasis to No.14v lymph node. Status of No.14v lymph node was an independent prognostic factor for GC staged TNM III. Patients with positive No.14v lymph node usually have a poor prognosis, while such patients without distant metastasis may beneift from a curative surgery.

    Various exercise interventions have been shown to benefit weight control and general health in different populations. However, very few studies have been conducted on martial arts exercise (MAE). The objective of this pilot study is to evaluate the efficacy of 12 weeks of MAE intervention on body composition, serum biomarkers and quality of life (QOL) in overweight/obese premenopausal women. We found that subjects in the MAE group did not lose body weight, while they significantly decreased fat-free mass and muscle mass as compared to those in the control group, who demonstrated an increase in these parameters. The MAE group demonstrated an increase in serum IGF-I concentration, but no change in others. MAE may be a feasible and effective approach to improve body composition and QOL in overweight/obese premenopausal women. Our study underscores the need for further studies using larger samples to establish possible benefits of MAE in various populations. PMID:24665215

    Objective To determine what ultrasonographic features can identify metastatic cervical lymph nodes, both preoperatively and in recurrences after complete thyroidectomy. Study Design Prospective. Setting Outpatient clinic, Department of Head and Neck Surgery, School of Medicine, University of São Paulo, Brazil. Subjects and Methods A total of 1976 lymph nodes were evaluated in 118 patients submitted to total thyroidectomy with or without cervical lymph node dissection. All the patients were examined by cervical ultrasonography, preoperatively and/or postoperatively. The following factors were assessed: number, size, shape, margins, presence of fatty hilum, cortex, echotexture, echogenicity, presence of microcalcification, presence of necrosis, and type of vascularity. The specificity, sensitivity, positive predictive value, and negative predictive value of each variable were calculated. Univariate and multivariate logistic regression analyses were conducted. A receiver operator characteristic (ROC) curve was plotted to determine the best cutoff value for the number of variables to discriminate malignant lymph nodes. Results Significant differences were found between metastatic and benign lymph nodes with regard to all of the variables evaluated ( P < .05). Logistic regression analysis revealed that size and echogenicity were the best combination of altered variables (odds ratio, 40.080 and 7.288, respectively) in discriminating malignancy. The ROC curve analysis showed that 4 was the best cutoff value for the number of altered variables to discriminate malignant lymph nodes, with a combined specificity of 85.7%, sensitivity of 96.4%, and efficiency of 91.0%. Conclusion Greater diagnostic accuracy was achieved by associating the ultrasonographic variables assessed rather than by considering them individually.

The filter function of lymph nodes, which led to the idea of including lymphatic treatment in surgical management of metastases. OBJECTIVES: To evaluate morphological alterations in neck nodes in the presence of differentiated thyroid carcinoma (DTC: hyperplasia, histiocytosis, desmoplasia, capsular rupture, necrosis and their relation to the biological behavior of these neoplasias. DESIGN: Retrospective study. SETTING: University referral unit. PARTICIPANTS: 98 DTC patients, from 1977 to 1992, 18 cases were selected for histological analyses, of which 14 were female and 4 males, with an average age of 50.2 years. From these cases, 290 lymph nodes were analyzed (81 with metastasis, with an average of 16 lymph nodes/patient. MAIN MEASUREMENTS: Morphological evaluation of paraffin cuts stained by HE was done using an optical microscope, looking for presence of the abovementioned neoplasias and their UICC-TNM (1997 staging. RESULTS: Sinus histiocytosis was 2.4 times more frequent in the absence of lymph node metastasis (pNo. Disease recurrence occurred in 5 patients, all of whom were more than 40 years old (p= 0.24 and 4 of whom had necrosis (p= 0.02. Six patients with predominance of paracortical hyperplasia (p= 0.02 did not show as much relapse into disease as those with less than 6 metastasis lymph nodes (p= 0.009. CONCLUSIONS: The presence of paracortical hyperplasia is associated with a better prognosis. The existence of necrosis or metastasis in more than 6 lymph nodes in patients over 40 years of age is related to higher risk of relapse of disease in DTC.

    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. A 70 year-old asymptomatic man presented with a prostate-specific antigen (PSA) of 7.45 ng/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 1.45 ng/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. 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. 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.

    Lymph node staging is of paramount importance for prognosis estimation and therapy stratification in colorectal cancer. A high number of harvested lymph nodes is associated with an improved outcome. Methylene blue-assisted lymph node dissection effectively improves the lymph node harvest and ensures sufficient staging. Now, the effect on node positivity rate and stage-related outcome was investigated. The study cohort with advanced lymph node dissection consisted of 669 colorectal cancer cases of all stages, which were collected between 2007 and 2012. A historical collection of 663 cases investigated with conventional techniques between 2002 and 2004 served as control. Lymph node harvest was dramatically improved in the study group with mean lymph node numbers of 34 ± 17 vs 13 ± 5 (Pcancer and is therefore extremely helpful. The hypothesis that it also provides a higher sensitivity in detecting metastases, however, could be not proved.

    Full Text Available Celiac disease is a gluten sensitive enteropathy that involves an abnormal immunological response to glutens in wheat, rye etc. It predominantly involves the small intestinal mucosa, though, extra luminal manifestations can also occur. One rare extraluminal manifestation is cavitatory mesenteric lymph node syndrome. It occurs in refractory celiac disease and is associated with poor prognosis due to various complications. The diagnosis is often made on imaging when cystic mesenteric lymph nodes with fat-fluid levels are seen and this can then be confirmed by histopathological examination. We recently had a typical case where we were able to make this diagnosis.

    We report a case of malakoplakia involving the pancreas in a 74-year-old man with associated regional lymphoadenopathy. Histological examination of both pancreas and lymph nodes revealed a diffuse histiocytic infiltrate containing numerous Michaelis-Gutmann bodies. Electron microscopy supported the diagnosis of malakoplakia and showed bacterial-like structures. Differential diagnosis includes myofibroblastic inflammatory tumor and histiocytic neoplasms. Lymph-node involvement during malakoplakia is extremely rare and it has never been documented microscopically. Lymphohematogenous spread of bacteria may be the cause of the nodal involvement, which, however, does not appear to influence the clinical course of the disease.

    Background Ovarian function suppression (OFS) significantly downregulates the concentration of plasma estrogens. However, it is unclear whether it offers any survival benefits if combined with adjuvant tamoxifen treatment in premenopausal women. This meta-analysis was designed to assess data from previous studies involving adjuvant tamoxifen treatment plus OFS in premenopausal breast cancer. Methods Electronic literature databases (PubMed, Embase, the Web of Science, and the Cochrane Library) were searched for relevant randomized controlled trials published prior to February 1, 2015. Only randomized controlled trials that compared tamoxifen alone with tamoxifen plus OFS for premenopausal women with breast cancer were selected. The evaluated endpoints were disease-free survival and overall survival. Results Four randomized controlled trials comprising 6,279 patients (OFS combination, n=3,133; tamoxifen alone, n=3,146) were included in the meta-analysis. There was no significant improvement in disease-free survival or overall survival with addition of OFS in either the whole population or the hormone receptor-positive subgroup. The risk of distant recurrence was not reduced with the addition of OFS in the whole population. A subgroup analysis showed that addition of OFS significantly improved overall survival in patients who were administered chemotherapy. Conclusion Based on the available studies, concurrent administration of OFS and adjuvant tamoxifen treatment for premenopausal women with breast cancer has no effect on prolonging disease-free survival and overall survival, excluding patients who were administered chemotherapy. It should not be widely recommended, except perhaps for women who were hormone-receptor positive and who were also administered adjuvant chemotherapy. PMID:26109867

    Although there is ample evidence supporting the effectiveness of physical activity in the prevention and treatment of osteoporosis, there are no previous studies to examine the effect of office-based brief high-impact exercise (HIE) on bone mineral density (BMD) in healthy premenopausal women. This study evaluated the effects of office-based HIE on BMD in healthy premenopausal Japanese women. Ninety-one healthy premenopausal women were randomized to receive stretching exercise (SE) or HIE (stretching, along with up to 5 × 10 vertical and versatile jumps) for 12 months. The BMD of the lumbar spine and proximal femur was measured using dual-energy X-ray absorptiometry. Several cardiovascular risk factors and leg strength also were assessed. An accelerometer-based recorder was used to measure daily impact loading in four 1-week samples. The progression of the HIE program was ensured by the accelerometer. Thirty-three women (71.7%) in the SE group and 34 (75.6%) in the HIE group completed the study. There was a significant difference in the change in the femoral neck BMD between the groups in favor of the HIE group [0.6% (95% CI: -0.4, 1.7) vs. -1.0% (95% CI: -2.2, 0.2)]. Adiponectin, LDL, HDL, and the leg strength of participants in both the groups improved during the intervention. These finding suggested that office-based brief HIE can be recommended for premenopausal women for preventing bone mineral loss.

    The female sexual response is complex and influenced by several biological, psychological, and social factors. Testosterone is believed to modulate a woman's sexual response and desire, because low levels are considered a risk factor for impaired sexual function, but previous studies have been inconclusive. To investigate how androgen levels and psychosocial factors are associated with female sexual dysfunction (FSD), including hypoactive sexual desire disorder (HSDD). The cross-sectional study included 428 premenopausal women 19 to 58 years old who completed a questionnaire on psychosocial factors and had blood sampled at days 6 to 10 in their menstrual cycle. Logistic regression models were built to test the association among hormone levels, psychosocial factors, and sexual end points. Five different sexual end points were measured using the Female Sexual Function Index and the Female Sexual Distress Scale: impaired sexual function, sexual distress, FSD, low sexual desire, and HSDD. Serum levels of total and free testosterone, androstenedione, dehydroepiandrosterone sulfate, and androsterone glucuronide were analyzed using mass spectrometry. After adjusting for psychosocial factors, women with low sexual desire had significantly lower mean levels of free testosterone and androstenedione compared with women without low sexual desire. None of the androgens were associated with FSD in general or with HSDD in particular. Relationship duration longer than 2 years and mild depressive symptoms increased the risk of having all the sexual end points, including FSD in general and HSDD in particular in multivariate analyses. In this large cross-sectional study, low sexual desire was significantly associated with levels of free testosterone and androstenedione, but FSD in general and HSDD in particular were not associated with androgen levels. Length of relationship and depression were associated with FSD including HSDD. Wåhlin-Jacobsen S, Kristensen E, Tønnes Pedersen A

    Full Text Available OBJECTIVE: There is no universal consensus on the relationship between body mass index (BMI and breast cancer. This meta-analysis was conducted to estimate the overall effect of overweight and obesity on breast cancer risk during pre- and post-menopausal period. DATA SOURCES: All major electronic databases were searched until April 2012 including Web of Knowledge, Medline, Scopus, and ScienceDirect. Furthermore, the reference lists and related scientific conference databases were searched. REVIEW METHODS: All prospective cohort and case-control studies investigating the association between BMI and breast cancer were retrieved irrespective of publication date and language. Women were assessed irrespective of age, race and marital status. The exposure of interest was BMI. The primary outcome of interest was all kinds of breast cancers confirmed pathologically. Study quality was assessed using the checklist of STROBE. Study selection and data extraction were performed by two authors separately. The effect measure of choice was risk ratio (RR(i and rate ratio (RR(a for cohort studies and odds ratio (OR in case-control studies. RESULTS: Of 9163 retrieved studies, 50 studies were included in meta-analysis including 15 cohort studies involving 2,104,203 subjects and 3,414,806 person-years and 35 case-control studies involving 71,216 subjects. There was an inverse but non-significant correlation between BMI and breast cancer risk during premenopausal period: OR = 0.93 (95% CI 0.86, 1.02; RR(i = 0.97 (95% CI 0.82, 1.16; and RR(a = 0.99 (95% CI 0.94, 1.05, but a direct and significant correlation during postmenopausal period: OR = 1.15 (95% CI 1.07, 1.24; RR(i = 1.16 (95% CI 1.08, 1.25; and RR(a = 0.98 (95% CI 0.88, 1.09. CONCLUSION: The results of this meta-analysis showed that body mass index has no significant effect on the incidence of breast cancer during premenopausal period. On the other hand, overweight and obesity may have a minimal effect on

    The almost constant local regional development of the cancers of upper aero digestive organs requires the same special attention to cervical lymph node metastases, as well as to the primary neoplastic burning point. The surgical therapy alone or associated has a mutilating, damaging character, resulting in loss of an organ and function, most of the times with social implications, involving physical distortions with aesthetic consequences, which make the reintegration of the individual into society questionable. The problem of cervical lymph node metastases is vast and complex, reason why we approached several anatomical and physiological aspects of lymph vessels of the aero digestive organs. Among the available elements during treatment, the headquarters of the tumour, its histologic degree, and its infiltrative nature, each of them significantly influences the possibility of developing metastases.

    Vascularized lymph node transfer is an effective surgical method in reducing lymphedema. This study provides the first detailed description of the surgical anatomy of the supraclavicular lymph node flap in regard to pedicle length, pedicle diameter, and the number of lymph nodes and their exact location inside the flap. Bilateral supraclavicular dissections of nine fresh cadavers (five female) were performed. Before the dissection, the exact number of lymph nodes was determined sonographically by an experienced radiologist, and their distance from the jugular notch was measured. After anatomic dissection, the vascular pedicle's diameter and length were measured. The mean number of lymph nodes was 1.5 ± 1.85 on the right side and 3 ± 2.26 on the left. Their mean distance from the jugular notch was 8.29 ± 2.15 cm on the right and 6.10 ± 1.21 cm on the left. The pedicle's length was 4.72 ± 1.03 cm on the right and 4.86 ± 0.99 cm on the left, and its diameter 2.03 ± 0.83 on the right and 1.80 ± 0.77 on the left. The pedicle length and diameter of the supraclavicular lymph node flap are suitable for a microvascular tissue transfer. J. Surg.

    Full Text Available Background : Diagnostic and therapeutic importance of pelvic lymph node (LN dissection (PLND in radical cystectomy (RC has gained recent attention. A method of pathological analysis of LN affects total number of LN removed, number of LN involved, and LN density. Objective : To compare extended lymphadenectomy to standard lymphadenectomy in terms of LN yield, density, and effect on survival. Materials and Methods : From Jan 2004 - July 2009, 78 patients underwent RC whose complete histopathological report was available for analysis. All were transitional cell carcinoma. From July 2007 onward extended LN dissection was started and LNs were sent in six packets. Twenty-eight patients of standard PLND kept in group I. Group II had 23 patients of standard PLND (LN sent in four packets, and group III had 23 patients of extended PLND (LN sent in six packets. SPSS 15 software used for statistical calculation. Results : Distribution of T-stage among three groups is not statistically significant. Median number of LN harvested were 5 (range, 1-25 in group I, 9 (range, 3-28 in group II, and 16 (range, 1-25 in group III. Although this is significant, we did not find significant difference in number of positive LN harvested. We did not find any patient with skip metastasis to common iliac LN in group 3. Conclusions : Separate package LN evaluation significantly increased the total number of LN harvested without increasing the number of positive LN and survival.

    Uncoupling protein-2 (UCP2) is a mitochondrial protein expressed in a wide range of human tissues. By uncoupling respiration from ATP synthesis, UCP2 might be involved in the control of energy expenditure. We have investigated UCP2 gene expression in human adipose tissue. In eight subjects, we found a positive correlation (r = 0.91, P < 0.002) between subcutaneous and visceral fat depots UCP2 messenger RNA (mRNA) levels, suggesting that UCP2 mRNA level in subcutaneous adipose tissue is a good index of UCP2 gene expression in whole body adipose tissues. The effect of a 25-day very-low-calorie diet un UCP2 mRNA level and resting metabolic rate was investigated in eight obese premenopausal women. There was no difference in UCP2 mRNA levels before and during the diet. After 25 days of hypocaloric diet, a positive correlation was found between adipose tissue UCP2 mRNA level and resting metabolic rate adjusted for lean body mass (r = 0.82, P < 0.01). These results show that very-low-calorie diet, unlike short-term fasting, is not associated with an induction in UCP2 mRNA expression, and that adipose tissue UCP2 mRNA levels may be related to variations in resting energy expenditure in humans.

    Full Text Available Abstract Background Increased health care costs have made it incumbent on health-care facilities and physicians to demonstrate both clinical and cost efficacy when recommending treatments. Though studies have examined the cost-effectiveness of adjuvant goserelin with radiotherapy for locally advanced prostate cancer, few have compared the cost-effectiveness of adjuvant goserelin to adjuvant chemotherapy alone in premenopausal breast cancer. Methods In this retrospective study at one hospital, the records of 152 patients with stage Ia to IIIa ER + breast cancer who received goserelin or chemotherapy were reviewed. Survival analysis was assessed by the Kaplan-Meier method. Patients were interviewed to evaluate their quality of life using the European Organization for Research and Treatment Quality of Life questionnaire (EORTC-QLQ-C30, version 4.0, and to obtain the utility value by the standard gamble (SG and visual scale (VS methods. Total medical cost was assessed from the (National Health Insurance NHI payer's perspective. Results Survival at 11 years was significantly better in the groserelin group (P Conclusions Goserelin therapy results in better survival and higher utility-weighted life-years, and is more cost-effective than TC or TEC chemotherapy.

    Full Text Available Background. Serotonin and brain-derived neurotrophic factor (BDNF are known to be modulators of nociception. However, pain-related connection between yoga and those neuromodulators has not been investigated. Therefore, we aimed to evaluate the effect of yoga on pain, BDNF, and serotonin. Methods. Premenopausal women with chronic low back pain practiced yoga three times a week for 12 weeks. At baseline and after 12 weeks, back pain intensity was measured using visual analogue scale (VAS, and serum BDNF and serotonin levels were evaluated. Additionally, back flexibility and level of depression were assessed. Results. After 12-week yoga, VAS decreased in the yoga group (P<0.001, whereas it increased (P<0.05 in the control group. Back flexibility was improved in the yoga group (P<0.01. Serum BDNF increased in the yoga group (P<0.01, whereas it tended to decrease in the control group (P=0.05. Serum serotonin maintained in the yoga group, while it reduced (P<0.01 in the control group. The depression level maintained in the yoga group, whereas it tended to increase in the control group (P=0.07. Conclusions. We propose that BDNF may be one of the key factors mediating beneficial effects of yoga on chronic low back pain.

    It is well known that plasma lipids, waist circumference (WC) and blood pressure (BP) increase following menopause. In addition, there is a perceived notion that plasma high-density lipoprotein-cholesterol (HDL-C) concentrations also decrease in postmenopausal women. In this cross-sectional study, we evaluated plasma lipids, fasting glucose, anthropometrics and BP in 88 post and 100 pre-menopausal women diagnosed with metabolic syndrome. No differences were observed in plasma low-density lipoprotein-cholesterol cholesterol, triglycerides, fasting glucose or systolic and diastolic BP between groups. However, plasma HDL-C was higher (p HDL (HDL-C (r = -0.148, p HDL-C (r = -0.258, p HDL-C. Interestingly, there was a positive correlation between age and plasma HDL-C (r = 0.237 p HDL is decreased by visceral fat and overall weight, low HDL is not a main characteristic of metabolic syndrome in postmenopausal women. Further, HDL appears to increase, not decrease, with age.

    A number of studies have called attention to the problematic interplay between depression and anxiety symptoms and sexual difficulties. However, despite the bidirectional conceptualization of the association between affective and sexual problems, few studies have adequately examined temporal precedence or state-level fluctuations between these two constructs. Using Clark and Watson's (1991) tripartite model of anxiety and depression, the current study employed a repeated measures design to examine how weekly changes in affective symptoms were related to weekly changes in sexual functioning in a non-clinical sample of premenopausal women. First, we examined how general distress, anxious arousal, and anhedonia were concurrently related to various indices of sexual functioning. Next, we examined lagged effects of mood and anxiety symptoms predicting later levels of sexual functioning. Finally, we tested sexual functioning's influence on later reports of affective symptoms. Hierarchical linear modeling analyses revealed that, of the three symptom types tested, anhedonic depression was the most consistently related to sexual problems, and that these relations were more proximal than distal. The preponderance of data suggested temporal precedence of mood on sexual symptoms. These findings emphasize the importance of prospective studies in the investigation of mental and sexual health.

    Full Text Available Background: The pathogenesis and etiology of endometrial polyps has not been elucidated. In this study, we aimed to examine the pathogenic mechanisms of endometrial polyp development using immunohistochemistry. We evaluated the expression of galectin-3 and cyclooxgenase-2 (COX-2 during the menstrual cycle in premenopausal women with endometrial polyps or normal endometrium. Methods Thirty-one patients with endometrial polyps and 50 healthy control patients were included in this study. The levels of expression of COX-2 and galectin-3 were studied by immunohistochemistry. Results: The percentage of COX-2–positive cells and the intensity of COX-2 staining in the endometrium did not vary during the menstrual cycle either in the control group or in patients with endometrial polyps. However, expression of galectin-3 was significantly lower in endometrial polyps and during the proliferative phase of the endometrium compared with the secretory phase. Conclusions: Our data suggests that the pathogenesis of endometrial polyps does not involve expression of COX-2 or galectin-3.

    Full Text Available PURPOSE: The aim of this study was to evaluate ERK phosphorylation as a stromal biomarker for breast cancer prognosis and tamoxifen treatment prediction within a randomized tamoxifen trial. PATIENTS AND METHODS: Tissue microarrays of two breast cancer cohorts including in total 743 invasive breast cancer samples were analyzed for ERK phosphorylation (pERK and smooth muscle actin-alpha expression (SMAα in cancer-associated fibroblasts (CAFs and links to clinico-pathological data and treatment-predictive values were delineated. RESULTS: By analyzing a unique randomized tamoxifen trial including breast cancer patients receiving no adjuvant treatment we show for the first time that patients low in ERK phosphorylation in CAFs did not respond to tamoxifen treatment despite having estrogen-receptor alpha (ERα-positive tumors compared to patients with high pERK levels in CAFs (P = 0.015, multivariate Cox regression interaction analysis. In both clinical materials we further show a significant association between pERK and SMAα, a characteristic marker for activated fibroblasts. SMAα expression however was not linked to treatment-predictive information but instead had prognostic qualities. CONCLUSION: The data suggests that the presence of a subpopulation of CAFs, defined by minimal activated ERK signaling, is linked to an impaired tamoxifen response. Thus, this report illustrates the importance of the stroma for monitoring treatment effects in pre-menopausal breast cancer.

    Coconut oil is a common edible oil in many countries, and there is mixed evidence for its effects on lipid profiles and cardiovascular disease risk. Here we examine the association between coconut oil consumption and lipid profiles in a cohort of 1,839 Filipino women (age 35-69 years) participating in the Cebu Longitudinal Health and Nutrition Survey, a community based study in Metropolitan Cebu. Coconut oil intake was estimated using the mean of two 24-hour dietary recalls (9.5±8.9 grams). Lipid profiles were measured in morning plasma samples collected after an overnight fast. Linear regression models were used to estimate the association between coconut oil intake and each plasma lipid outcome after adjusting for total energy intake, age, body mass index (BMI), number of pregnancies, education, menopausal status, household assets and urban residency. Dietary coconut oil intake was positively associated with high density lipoprotein cholesterol especially among pre-menopausal women, suggesting that coconut oil intake is associated with beneficial lipid profiles. Coconut oil consumption was not significantly associated with low density lipoprotein cholesterol or triglyceride values. The relationship of coconut oil to cholesterol profiles needs further study in populations in which coconut oil consumption is common.

    Recent studies have demonstrated a strong correlation between obesity, insulin resistance, increased insulin and insulin-like growth factor levels and the risk of breast cancer. Our study was aimed at exploring correlations between glucose, insulin, insulin resistance, obesity and quantitatively estimated breast elasticity in healthy women. The pilot study included 37 premenopausal women aged 22-45 years who underwent B-mode sonography and real-time shear wave elastography. Blood was collected for fasting insulin and glucose, and HOMA insulin resistance index was calculated. The mean elasticity of glandular and fatty tissue measured in both breasts was 12.5 ±3.5 kPa and 10.9 ±3.7 kPa respectively. Insulin levels did not correlate with glandular tissue elasticity (Rs=-0.23, p=0.15), but nearly correlated with fat tissue elasticity (Rs=-0.30, p=0.06), in outer quadrants significantly (Rs=-0.38, p=0.02). Interestingly, a strong correlation of insulin and insulin resistance with elasticity heterogeneity was found in fatty tissue (Rs=-0.59, p<0.001 and Rs=-0.60, p<0.001 respectively). The heterogeneity of fatty tissue but not glandular elasticity also correlated with body mass index. Insulin levels and insulin resistance correlate with breast fat tissue heterogeneity, but their role in breast pathology remains unclear.

    In premenopausal women, elevated C-reactive protein (CRP) concentrations have been associated with an increased risk of negative reproductive outcomes. Whole grain consumption has been associated with lower CRP concentrations in older women; however, less is known about this relationship in younger women. We investigated whether whole grain intake was associated with serum high sensitivity CRP (hs-CRP) concentrations in young women. BioCycle was a prospective cohort study conducted at the University of Buffalo from 2005 to 2007, which followed 259 healthy women aged 18-44 y for Whole grain intake was estimated by 24-h recalls whole grain food. Whole grain intake was inversely associated with hs-CRP concentrations after adjusting for age, race, BMI, illness, and antiinflammatory drug use. Consumers of between 0 and 1 serving/d of whole grains had, on average, 11.5% lower hs-CRP concentrations (P = 0.02) and consumers of >or= 1 serving/d had 12.3% lower hs-CRP concentrations (P = 0.02) compared with nonconsumers. Women who consumed >or= 1 serving/d of whole grain had a lower probability of having moderate (P = 0.008) or elevated (P = 0.001) hs-CRP according to the AHA criteria compared with nonconsumers. Given that elevated concentrations of hs-CRP have been linked to adverse reproductive outcomes and pregnancy complications, interventions targeting whole grain consumption may have the potential to improve health status among young women.

  2. Retroperitoneal unicentric Castleman's disease (giant lymph node hyperplasia: case report

    Directory of Open Access Journals (Sweden)

    Jaques Waisberg

    Full Text Available CONTEXT AND OBJECTIVE: 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. CASE REPORT: 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.

    The aim of this study was to evaluate the usefulness and accuracy of supraclavicular lymph node excision biopsy in the diagnosis of suspected supraclavicular lymph node metastasis of lung cancer. A retrospective review was performed to evaluate patients with suspected supraclavicular lymph node metastasis of lung cancer who underwent supraclavicular lymph node excision biopsy from January 2011 to July 2014. Forty-six patients with suspected supraclavicular lymph node metastasis of lung cancer underwent supraclavicular lymph node excision biopsy, which diagnosed benign diseases in 6 patients and malignant diseases in 40 patients. Supraclavicular lymph node excision biopsy was usually performed on patients during their first clinical visit under local anesthesia. For diagnosing suspected lung cancer, supraclavicular lymph node excision biopsy had a diagnostic sensitivity of 100%, specificity of 97.6%, positive-predictive value of 83.3%, negative-predictive value of 100%, and accuracy of 97.8%. No major complication resulted from surgical intervention. Supraclavicular lymph node excision biopsy is a useful and accurate adjunct for the evaluation of suspected supraclavicular lymph node metastasis of lung cancer in a tertiary hospital. PMID:28184341

    Regional lymph node metastases are an important predictor of survival for patients with resectable adenocarcinoma of the stomach. Currently, the number of lymph nodes examined is frequently less than requirements for accurate staging. Clinical factors associated with lymph node recovery are understood poorly. We performed a retrospective chart review of 99 consecutive patients who underwent gastrectomy for gastric adenocarcinoma distal to the gastroesophageal junction to determine clinical variables associated lymph node recovery. Ninety-nine patients underwent gastrectomy for gastric adenocarcinoma at our two hospitals. More than 15 lymph nodes were examined in 64% of specimens. Univariate analysis showed an association between the number of lymph nodes recovered and the number of positive nodes, lymphadenectomy extent, hospital, surgeon, and pathology technician (p analysis identified the pathology technician as the most important healthcare-related variable contributing to the variation of lymph node recovery, using fixed- (p technical aspects of specimen processing may be of benefit in maximizing the number of lymph nodes recovered.

  13. Abnormal position of lymph nodes in a freemartin sheep

    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

Non-small cell lung cancer (NSCLC accounts for nearly 80% of all lung malignancies. Surgical resection is still the current major treatment method for early stage NSCLC. Lymph node stages together with the extent of lymph node dissection directly affect the prognosis. Anatomical lobectomy with systematic mediastinal lymph node dissection have been the standard surgical treatment for NSCLC. However, it is controversial in the extent of lymph node dissection for early stage NSCLC. Accurate nodes stage and the extent of mediatinal nodes dissection affect the peri-operative complications and the prognosis of NSCLC greatly. In the past decade, more and more surgeons demostrated that lobe-specific or selective mediastinal lymph node dissection is suitable for clinical stage I NSCLC, especially the stage Ia lesions, and may become the standard lymph node dissection mode in the future.

    We evaluated the diagnostic value of {sup 18}F-FDG PET/CT (PET/CT) in lymph node staging of non-small cell lung cancer (NSCLC) considering calcification and histologic types as well as FDG uptake. Fifty-three patients (38 men, 15 women; mean age, 62 years) with NSCLC underwent surgical resection (tumor resection and lymph node dissection) after PET/CT. After surgery, we compared PET/CT results with the biopsy results, and analyzed lymph node metastases, based on histologic types. PET diagnosis of lymph node metastasis was determined by maximum SUV (maxSUV) > 3.0, and PET/CT diagnosis was determined by maxSUV > 3.0 without lymph node calcification. By PET diagnosis, the sensitivity, specificity, and accuracy of overall lymph node staging were 45% (13 of 29), 91% (228 of 252), and 86% (241 of 281). Specificity was 91% in both squamous cell carcinoma and adenocarcinoma, while sensitivity was 71% in squamous cell carcinoma and 36% in adenocarcinoma. When we excluded calcified lymph node with maxSUV > 3.0 from metastasis by PET/CT diagnosis, specificity improved to 98% in squamous cell carcinoma and 97% in adenocarcinoma. The degree of improvement was not dependent on histologic types. PET/CT improved specificity of lymph node staging by reducing false positive lymph node regardless of histologic types of NSCLC.

    Abstract Introduction We previously reported an association between tumor-specific 3-hydroxy-3-methylglutharyl-coenzyme A reductase (HMG-CoAR) expression and a good prognosis in breast cancer. Here, the predictive value of HMG-CoAR expression in relation to tamoxifen response was examined. Methods HMG-CoAR protein and RNA expression was analyzed in a cell line model of tamoxifen resistance using western blotting and PCR. HMG-CoAR mRNA expression was examined in 155 tamoxifen-treated breast tumors obtained from a previously published gene expression study (Cohort I). HMG-CoAR protein expression was examined in 422 stage II premenopausal breast cancer patients, who had previously participated in a randomized control trial comparing 2 years of tamoxifen with no systemic adjuvant treatment (Cohort II). Kaplan-Meier analysis and Cox proportional hazards modeling were used to estimate the risk of recurrence-free survival (RFS) and the effect of HMG-CoAR expression on tamoxifen response. Results HMG-CoAR protein and RNA expression were decreased in tamoxifen-resistant MCF7-LCC9 cells compared with their tamoxifen-sensitive parental cell line. HMG-CoAR mRNA expression was decreased in tumors that recurred following tamoxifen treatment (P < 0.001) and was an independent predictor of RFS in Cohort I (hazard ratio = 0.63, P = 0.009). In Cohort II, adjuvant tamoxifen increased RFS in HMG-CoAR-positive tumors (P = 0.008). Multivariate Cox regression analysis demonstrated that HMG-CoAR was an independent predictor of improved RFS in Cohort II (hazard ratio = 0.67, P = 0.010), and subset analysis revealed that this was maintained in estrogen receptor (ER)-positive patients (hazard ratio = 0.65, P = 0.029). Multivariate interaction analysis demonstrated a difference in tamoxifen efficacy relative to HMG-CoAR expression (P = 0.05). Analysis of tamoxifen response revealed that patients with ER-positive\\/HMG-CoAR tumors had a significant response to tamoxifen (P = 0.010) as well as

    The purpose of this study was to investigate potential risk factors for failed sentinel lymph node identification in breast cancer surgery. Patient characteristics, tumour characteristics, surgeon experience and detection success/failure were registered at 748 sentinel lymph node biopsy procedures...... at our inpatient clinic. Data were analysed with backward stepwise multiple logistic regression with a cut-off point of psentinel lymph node detection rate....... Tumour size, palpability and biopsy method were not significantly associated with the sentinel lymph node detection rate. In conclusion, it is possible to identify patients with a higher risk of sentinel lymph node identification failure and we recommend that these patients are operated by experienced...

    What is the impact of intentional weight loss and regain on serum androgens in women? We conducted an ancillary analysis of prospectively collected samples from a randomized controlled trial. The trial involved supervised 10% weight loss (8.5 kg on average) with diet and exercise over 4-6 months followed by supervised intentional regain of 50% of the lost weight (4.6 kg on average) over 4-6 months. Participants were randomized prior to the partial weight regain component to either continuation or cessation of endurance exercise. Analytic sample included 30 obese premenopausal women (mean age of 40 ± 5.9 years, mean baseline body mass index (BMI) of 32.9 ± 4.2 kg/m(2)) with metabolic syndrome. We evaluated sex hormone binding globulin (SHBG), total testosterone (T), free androgen index (FAI), and high molecular weight adiponectin (HMWAdp). Insulin, homeostasis model assessment (HOMA), and quantitative insulin sensitivity check index (QUICKI), and visceral adipose tissue (VAT) measured in the original trial were reanalyzed for the current analytic sample. Insulin, HOMA, and QUICKI improved with weight loss and were maintained despite weight regain. Log-transformed SHBG significantly increased from baseline to weight loss, and then significantly decreased with weight regain. LogFAI and logVAT decreased similarly and increased with weight loss followed by weight regain. No changes were found in logT and LogHMWAdp. There was no significant difference in any tested parameters by exercise between the groups. SHBG showed prominent sensitivity to body mass fluctuations, as reduction with controlled intentional weight regain showed an inverse relationship to VAT and occurred despite stable HMWAdp and sustained improvements with insulin resistance. FAI showed opposite changes to SHBG, while T did not change significantly with weight. Continued exercise during weight regain did not appear to impact these findings.

    The possibility of inflammation and neutrophil activation in response to indoor air pollution (IAP) from biomass fuel use has been investigated. For this, 142 premenopausal, never-smoking women (median age, 34 years) who cook exclusively with biomass (wood, dung, crop wastes) and 126 age-matched control women who cook with cleaner fuel liquefied petroleum gas (LPG) were enrolled. The neutrophil count in blood and sputum was significantly higher (p enzyme-linked immunosorbent assay showed that they had 72%, 67%, and 54% higher plasma levels of the proinflammatory cytokines tumor necrosis factor-alpha, interleukin-6, and interleukin-12, respectively, and doubled neutrophil chemoattractant interleukin-8. Immunocytochemical study revealed significantly higher percentage of airway neutrophils expressing inducible nitric oxide synthase, while the serum level of nitric oxide was doubled in women who cooked with biomass. Spectrophotometric analysis documented higher myeloperoxidase activity in circulating neutrophils of biomass users, suggesting neutrophil activation. Flow cytometry showed excess generation of reactive oxygen species (ROS) by leukocytes of biomass-using women, whereas their erythrocytes contained a depleted level of antioxidant enzyme superoxide dismutase (SOD). Indoor air of biomass-using households had two to four times more particulate matter with diameters of <10 μm (PM(10)) and <2.5 μm (PM(2.5)) as measured by real-time laser photometer. After controlling potential confounders, rise in proinflammatory mediators among biomass users were positively associated with PM(10) and PM(2.5) in indoor air, suggesting a close relationship between IAP and neutrophil activation. Besides, the levels of neutrophil activation and inflammation markers were positively associated with generation of ROS and negatively with SOD, indicating a role of oxidative stress in mediating neutrophilic inflammatory response following chronic inhalation of biomass smoke.

    Objective: In this study, we evaluated the effect of supraclavicular lymph node dissection in breast cancer patients who presented with ipsilateral supraclavicular lymph node metastasis (ISLM) without distant metastasis. Methods: A total of 90 patients with synchronous ISLM without distant metastasis between 2000 and 2009 were retrospectively analyzed. Patients were retrospectively divided into two groups, namely supraclavicular lymph node dissection group(34 patients) and non-dissection group(56 patients), according to whether they underwentsupraclavicular lymph node dissection or not.The Kaplan-Meier method was applied to analyze the locoregional relapse free survival (LRFS) and overall survival(OS). Results: Median follow-upwas 85 months(range, 6 to 11 months). Local recurrence in 32 cases, 47 cases of distant metastasis, of which 25 patients were accompanied by both locoregional relapse and distant metastasis. Of the 32 patients with locoregional relapse, 11 patients were in the lymph node dissection group and 21 patients in the control group. Of the 47 patients with distant metastases, 17 were treated with lymph node dissection, 30 in the control group. Thirty-two patients died in the whole group and 16 patients underwentlymph node dissection and 16 patients didn't. There was no significant difference between the rate of 5-year LRFS and 5-year OS (P=0.359, P=0.246). For patients of ER negative, the 5-year loco-regional relapse free survival rates were 63.7% and 43.3% in supraclavicular lymph node dissection group and control group, respectively. The 5-year overall survival rates were 52.1% and 52.3%, respectively, and there were no statistically significant differences (P=0.118, P=0.951). For patients of PR negative, the 5-yearloco-regional relapse free rates were 59.8% and 46.2%, respectively, and the 5-year overall survival rates were 50.6% and 43.2%, respectively, and there was no significant difference between the two groups (P=0.317, P=0.973).

    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.

    The lymphatic circulation is still a somewhat forgotten part of the circulatory system. Despite this, novel insights in lymph angiogenesis in health and disease, application of immune markers for lymphatic growth and differentiation and also the introduction of new imaging techniques to visualize the lymphatic circulation have improved our understanding of lymphatic function in both health and disease, especially in the last decade. These achievements yield better understanding of the various manifestations of lymph oedemas and malformations, and also the patterns of lymphovascular spread of cancers. Immune markers that recognize lymphatic endothelium antigens, such as podoplanin, LYVE-1 and Prox-1, can be successfully applied in diagnostic pathology and have revealed (at least partial) lymphatic differentiation in many types of vascular lesions.

    Distinguishing between malignant mesothelioma and reactive mesothelial hyperplasia is often inestimable, but may be a challenging gauntlet for pathologists. A 62-year-old man underwent appendectomy after the identification of a peritoneal mass and the histological examination showed mesothelial proliferation along the appendix surface with no clear images of infiltration. After a few months the patient developed mediastinal and supraclavicular lymphadenopathies, and a nodal biopsy showed mesothelial cell proliferation invading lymphatic sinuses, consistent with the cells seen in the abdominal cavity. Since overt morphologic criteria for malignancy were lacking and reactive mesothelial cell deposits have been documented in lymph nodes, a molecular investigation of the CDKN2A (henceforth simply p16) gene status via fluorescence in situ hybridization was performed, which showed homozygous deletion in 100% tumor cells. These data ruled out the hypothesis of reactive mesothelial cells inclusion in lymph nodes, thus confirming the diagnosis of epithelioid malignant mesothelioma. © The Author(s) 2014.

    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.

    Sentinel lymph nodes (SLNs) are the first lymph nodes which cancer cells reach after traveling through lymphatic vessels from the primary tumor. Evaluating the nodal status is crucial in accurate staging of human cancers and accordingly determines prognosis and the most appropriate treatment. The commonly used methods for SLN identification in clinics are based on employment of a colloid of radionuclide or injection of a small dye. Although these methods have certainly contributed to improve surgical practice, new imaging materials are still required to overcome drawbacks of the techniques such as inconvenience of handling radioactive materials and short retention time of small dyes in SLNs. Here, we prepare a fluorescence-labeled DNA tetrahedron and perform SLN imaging by using the DNA nanoconstruct. With a successful identification of SLNs by the DNA nanoconstruct, we suggest that DNA tetrahedron hold great promises for clinical applications.

  4. High definition infrared spectroscopic imaging for lymph node histopathology.

    Directory of Open Access Journals (Sweden)

    L Suzanne Leslie

    Full Text Available Chemical imaging is a rapidly emerging field in which molecular information within samples can be used to predict biological function and recognize disease without the use of stains or manual identification. In Fourier transform infrared (FT-IR spectroscopic imaging, molecular absorption contrast provides a large signal relative to noise. Due to the long mid-IR wavelengths and sub-optimal instrument design, however, pixel sizes have historically been much larger than cells. This limits both the accuracy of the technique in identifying small regions, as well as the ability to visualize single cells. Here we obtain data with micron-sized sampling using a tabletop FT-IR instrument, and demonstrate that the high-definition (HD data lead to accurate identification of multiple cells in lymph nodes that was not previously possible. Highly accurate recognition of eight distinct classes - naïve and memory B cells, T cells, erythrocytes, connective tissue, fibrovascular network, smooth muscle, and light and dark zone activated B cells was achieved in healthy, reactive, and malignant lymph node biopsies using a random forest classifier. The results demonstrate that cells currently identifiable only through immunohistochemical stains and cumbersome manual recognition of optical microscopy images can now be distinguished to a similar level through a single IR spectroscopic image from a lymph node biopsy.

    Cardiac involvement in systemic sarcoidosis sometimes provokes life-threatening ventricular tachyarrhythmia. Steroid administration is one of the fundamental anti-arrhythmia therapies. For an indication of steroid therapy, a definitive diagnosis of sarcoidosis is required.(1)) However, cases that are clearly suspected of cardiac sarcoidosis based on their clinical courses sometimes do not meet the current diagnostic criteria and result in the loss of an appropriate opportunity to perform steroid therapy.Here we report a case that was diagnosed as sarcoidosis by incidental biopsy of an inguinal lymph node during cardiac resuscitation for cardiac tamponade.(2)) While the inguinal lymph node was not swollen on computed tomography, a specimen obtained from an incidental biopsy during the exposure of a femoral vessel for the establishment of extracorporeal cardio-pulmonary resuscitation showed a non-caseating granuloma.This findings suggest a non-swelling lymph node biopsy might be an alternative strategy for the diagnosis for sarcoidosis if other standard strategies do not result in a diagnosis of sarcoidosis.

    Full Text Available PURPOSE: Pre-menopausal women with cancer are at risk of therapy-associated infertility, premature menopause, and sexual dysfunction. However, it is unknown whether oncologists adequately address these risks during treatment planning. We conducted a study to evaluate physician-patient discussions addressing the impact of cancer treatment and actual treatment effects on fertility, menopause status, and general sexual health.METHODS: A questionnaire was administered in four oncology clinics specializing in breast, gynecologic, general hematology-oncology, and blood and marrow transplantation (BMT cancer care at a single institution. Eligible participants were pre-menopausal at the time of diagnosis and either actively receiving or within 24 months from completion of treatment. Participants completed the questionnaire at enrollment and at 1-year follow-up.RESULTS: Of the 104 eligible women, a majority were satisfied with the quality (68% and length (66% of reproductive health discussions, with the highest satisfaction levels in the gynecologic cancer clinic (85% and the lowest levels in the BMT clinic (53%. Fertility preservation was desired by 20% of women, including some >40 years old. Women were more interested in discussing treatment impact on menopause status and sexual health than fertility. Rates of discussions on treatment impact on sexual health were low despite 77% of women reporting severe sexual dysfunction at 1-year follow-up.CONCLUSIONS: One-third of women are dissatisfied with the quality and length of discussions regarding the impact of cancer treatment on reproductive health. There is notably inadequate counseling on the effect of treatment on fertility in women > 40 and on sexual function in all women. Oncologists must offer better resources and improve communication on the effect of treatment on reproductive health to pre-menopausal women with cancer.

    The aim is to compare hysteroscopy, two-dimensional transvaginal ultrasound (2D TVUS), and three-dimensional (3D) Virtual Organ Computer-aided AnaLysis™ (VOCAL) to detect endometrial polyps (EPs) in premenopausal women with abnormal uterine bleeding (AUB). This prospective study was done at Ain Shams Maternity Hospital, Egypt, from March 5, 2015, to December 30, 2015, enrolling 118 premenopausal women with AUB. 2D TVUS, 3D VOCAL, and hysteroscopy were done. 109 patients reached final analysis. 36 women (33%) were diagnosed with EP by 2D TVUS. 50 (45.9%) had EP by hysteroscopy. Endometrial thickness was 10.1 mm by 2D TVUS and endometrial volume was 4.92 mL by VOCAL in women with EP by hysteroscopy compared to 9.9 mm and 3.50 mL in women with no EP, respectively (P = 0.223; P = 0.06). 2D TVUS has sensitivity, specificity, and positive and negative predictive values of 54%, 84.7%, 75%, and 68.5%, respectively. Endometrial thickness of >7.5 mm has sensitivity, specificity, positive and negative predictive values, and overall accuracy of 82%, 37.3%, 52.6%, 71%, and 57.8%, respectively. Endometrial volume of >1.2 mL has sensitivity, specificity, positive and negative predictive values, and overall accuracy of 90%, 42.4%, 57%, 83.3%, and 64.2%, respectively. 3D VOCAL may be used as a noninvasive method for the diagnosis of EP in premenopausal women with AUB.

    Introduction Uterine leiomyomas are the most common benign gynecologic tumors. To date laparoscopy myomectomy is the gold standard for treatment of symptomatic fibroids in reproductive-aged women. Detailed counseling about the effects of this procedure on postoperative sexuality and quality of life is important in these patients. However, available data on these subjects are limited and contradictory. The aim of this study was to assess sexual function and quality of life in premenopausal women undergoing laparoscopic myomectomy for symptomatic uterine fibroids. Material and Methods All premenopausal women who underwent laparoscopic myomectomy for symptomatic fibroids between April 2012 and August 2014 at a tertiary university center were enrolled in this prospective observational cohort study. Sexual function and quality of life were assessed for the pre- and postoperative (six months post-operatively) state using two validated questionnaires, the Female Sexual Function Index (FSFI) and the European Quality of Life Five-Dimension Scale (EQ-5D). Results Ninety-five of the 115 (83%) eligible patients completed the study. Overall a significant improvement in quality of life and sexual function was observed in the study cohort: Median FSFI (28 (18.7–35.2)) and EQ-5D scores (1 (0.61–1) after laparoscopic myomectomy were significantly higher than preoperative scores (21.2 (5.2–33.5); 0.9 (0.2–1); p ≤ 0.01). The number, position and localization of the largest fibroids were not correlated with pre- or postoperative sexual function or quality of life. Conclusion Laparoscopic myomectomy might have positive short-term effects on postoperative quality of life and sexual function in premenopausal women suffering from symptomatic fibroids.

    Low-fat and low-carbohydrate weight-loss diets can have a beneficial effect on longitudinal measures of blood pressure and blood lipids. We aimed to assess longitudinal changes in blood pressure and blood lipids in a population of premenopausal women. We hypothesized that results may differ by level of adherence to the respective diet protocol and baseline presence of hypertension or hyperlipidemia. Overweight or obese premenopausal women were randomized to a low-fat (n=41) or low-carbohydrate (n=38) diet. As part of the 52-week Lifestyle Eating and Fitness (LEAF) intervention trial, we fit linear mixed models to determine whether a change in outcome differed by treatment arm. Within-group trends in blood pressure and blood lipids did not differ (p>0.30). Across study arms, there was a significant decrease in systolic blood pressure (SBP, 3 mm Hg, p=0.01) over time, but diastolic blood pressure (DBP) did not change significantly over the course of the study. Blood lipids (total cholesterol [TC], low-density lipoproteins [LDL], and high-density lipoproteins [HDL]) all exhibited nonlinear trends over time (p0.20). We observed a decline in SBP among women who were hypertensive at baseline (p0.40). Our results support that dietary interventions may be efficacious for lowering blood pressure and blood lipids among overweight or obese premenopausal women. However, a decrease in SBP was the only favorable change that was sustained in this study population. These changes can be maintained over the course of a 1-year intervention, yet changes in blood lipids may be less sustainable.

    Corneal transplantation (keratoplasty) is the most frequently performed form of transplantation worldwide. A rejection reaction against the transplant is the main complication occurring after transplantation in an already vascularized, so-called "high-risk" recipient eye. Our group has shown that clinically invisible lymphatic vessels play a crucial role in the induction of a rejection reaction against the corneal graft, and that anti-(lymph)angiogenic therapies in the mouse model of keratoplasty can significantly improve transplant survival. The underlying mechanisms, which improve transplant survival through anti-lymphangiogenic therapies have not been well understood. We assume that the blockade of lymph vessel sprouting leads to a tolerance (and not to a simple ignorance) of the transplant, in which the antigen-presenting cells are held longer in the cornea and, thus, an immunomodulation of these cells occurs. Therefore, an important goal of our project is to find out whether and when transplant tolerance comes from a corneal anti-lymphangiogenic therapy. We assume that the antigen-presenting cells will have a different maturity level and that more tolerogenic effector cells (regulatory T cells, Tregs) develop in the absence of lymphatic vessels. Current anti(lymph)angiogenic therapies have the disadvantage that they are primarily effective on actively growing vessels. Most patients who receive high-risk keratoplasty often present in the clinic with already established, mature corneal blood and lymphatic vessels. At present, there are no lymph vessel regressing strategies, and the mechanisms regulating the maturation of the lymphatics are largely unknown. Therefore, our second goal is to develop new strategies for the regression of existing, pathological lymphatic vessels in the cornea. We are testing both destructive strategies, such as photodynamic therapy and diathermy as well as strategies for the molecular destabilization of the lymph vessel endothelium

    Background The purpose of this study was to investigate the feasibility of avoiding axillary lymph node dissection (ALND) for patients with only one sentinel lymph node (SLN) metastasis.The characteristics and predictive factors for non-sentinel lymph node (NSLN) metastasis of patients with single positive SLN were also analyzed.Methods Patients with no and only one SLN metastasis (0/n and 1/n group,n ≥2) were selected from 1228 cases of invasive breast carcinoma,who underwent axillary dissection in Shandong Cancer Hospital between November 1999 and December 2011,to compare the characteristics of NSLN metastasis between them.For the 1/n group,the factors that influenced the NSLN metastasis were analyzed by univariate and multivariate analysis.Results Differences of the NSLN metastasis between the 0/n and the 1/n groups were significant (P <0.001).There was no significant difference between the axillary lymph node metastasis on level Ⅲ in 1/n group and 0/n group (P=0.570).When the total SLN number was ≥4 and with one positive case,the NSLN metastasis was not significantly different from that in the 0/n group (P=0.118).In the 1/n group,clinical tumor size (P =0.012),over-expression of Her-2 (P=0.003),tumor grade (P=-0.018) and the total number of SLN (P=-0.047) significantly correlated with non-SLN metastasis.Clinical tumor size (P=-0.015) and the expression of Her-2 (P=0.01) were independent predictive factors for non-SLN metastasis by the Logistic regression model.Conclusion Under certain conditions,breast cancer patients with single SLN metastasis could avoid ALND.

    Positron emission tomography/computed tomography (PET/CT) imaging with fluorodeoxyglucose (FDG) have been used as a powerful fusion modality in nuclear medicine not only for detecting cancer but also for staging and therapy monitoring. Nevertheless, there are various causes of FDG uptake in normal and/or benign tissues. The purpose of present study was to investigate whether additional delayed imaging can improve the diagnosis to differentiate the rates of FDG uptake at axillary lymph nodes (ALN) between malignant and benign in breast cancer patients. 180 PET/CT images were obtained for 27 patients with ALN uptake. The patients who had radiotherapy and chemotherapy were excluded from the study. {sup 18}F-FDG PET/CT scan at 50 min (early phase) and 90 min (delayed phase) after {sup 18}F-FDG injection were included in this retrospective study. The staging of cancers was confirmed by final clinical according to radiologic follow-up and pathologic findings. The standardized uptake value (SUV) of ALN was measured at the Syngo Acquisition Workplace by Siemens. The 27 patients included 18 malignant and 9 ALN benign groups and the 18 malignant groups were classified into the 3 groups according to number of metastatic ALN in each patient. ALNs were categorized less than or equal 3 as N1, between 4 to 9 as N2 and more than 10 as N3 group. Results are expressed as the mean ± standard deviation (S.D.) and statistically analyzed by SPSS. As a result, Retention index (RI-SUV max) in metastasis was significantly higher than that in non-metastasis about 5 fold increased. On the other hand, RI-SUV max in N group tended to decrease gradually from N1 to N3. However, we could not prove significance statistically in malignant group with ANOVA. As a consequence, RI-SUV max was good indicator for differentiating ALN positive group from node negative group in breast cancer patients. These results show that dual-time-point scan appears to be useful in distinguishing malignant from benign.

    There is some controversy about the value of sentinel lymph node excision (SLNE) in patients with head and neck malignancies. The gold standard for detection and targeted extirpation of the SLN is lymphoscintigraphy with {sup 99m}Tc-nanocolloid. The purpose of this prospective randomized study was to analyse the feasibility and clinical benefit of a hybrid tracer comprising the near-infrared (NIR) fluorescent indocyanine green (ICG) and {sup 99m}Tc-nanocolloid (ICG-{sup 99m}Tc-nanocolloid) in direct comparison with standard {sup 99m}Tc-nanocolloid for guiding SLNE in patients with head and neck cutaneous malignancies. We analysed the data from 40 clinically lymph node-negative patients with melanoma, high-risk cutaneous squamous cell carcinoma, Merkel cell carcinoma or sweat gland carcinoma who underwent SLNE with ICG-{sup 99m}Tc-nanocolloid (cohort A) or with the standard {sup 99m}Tc-nanocolloid (cohort B). Overall SLNs were identified preoperatively in all 20 patients (100 %) in cohort A and in 18 of 20 patients (90 %) in cohort B. The SLN basin was detected preoperatively in 18 patients (90 %) in cohort A and also in 18 patients (90 %) in cohort B. SLNs were identified intraoperatively in all 20 patients (100 %) in cohort A and in 19 patients (95 %) in cohort B (p = 0.487). Metastatic SLNs were detected in 9 patients (22.5 %), 3 (15.0 %) in cohort A and 6 (30.0 %) in cohort B (p = 0.228). The hybrid tracer ICG-{sup 99m}Tc-nanocolloid is an innovative imaging tracer, reliably and readily providing additional information for the detection and excision of SLN in the head and neck region. Therefore, SLNE with combined radioactive and NIR fluorescence guidance is an attractive option for improving the SLN detection rate in patients with cutaneous head and neck malignancies. (orig.)

    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.

    Lymph node metastasis in patients with prostate cancer indicates a poorer prognosis compared with patients without lymph node metastasis; however, some patients with node-positive disease have long-term survival. Many studies have attempted to discern what characteristics of lymph node metastasis are prognostically significant. These characteristics include nodal tumor volume, number of positive lymph nodes, lymph node density, extranodal extension, lymphovascular invasion and tumor dedifferentiation. Favorable characteristics of regional lymph node involvement included a smaller tumor size and smaller tumor volume. However, the current staging system for prostate cancer does not provide different subclassifications for patients with node-positive prostate cancer. In recent years numerous advanced technologies for the detection of lymph node metastasis have been developed, including molecular imaging techniques and the CellSearch Circulating Tumor Cell System. With the increased detection of patients with prostate cancer, emergence of new technology to identify lymph node metastasis and the number of radical prostatectomies being performed on the rise, subclassifying patients with lymph node-positive disease is imperative. Subclassification would provide a better picture of patient prognosis and allow for a better understanding of targeted therapies to treat patients with lymph node metastasis.

    AIM: To elucidate the relationship between lymph nodesinuses with blood and lymphatic metastasis of gastric cancer.METHODS: Routine autopsy was carried out in the randomlyselected 102 patients (among them 100 patients died ofvarious diseases, and 2 patients died of non-diseasedreasons), their superficial lymph nodes locating in bilateralnecks (include supraclavicle), axilla, inguina, thorax, andabdomen were sampled. Haematoxylin-Eosin staining wasperformed on 10 % formalin-fixed and paraffin-embeddedlymph node tissue sections (Sum). The histological pattemsof the lymph sinuses containing blood were observed underlight microscope. The expression of CD31, a marker forendothelial cell, was detected both in blood and non-bloodcontaining lymph node sinuses with the method ofimmunohistochemistry.RESULTS: Among the 1322 lymph nodes sampled fromthe autopsies of 100 diseased cases, lymph node sinusescontaining blood were found in 809 lymph nodes sampledfrom 91 cases, but couldn't be seen in the lymph nodessampled from the non-diseased cases. According to histology,we divided the blood containing lymph node sinuses intofive categories: vascular-opening sinus, blood-deficient sinus,erythrophago-sinus, blood-abundant sinus, vascular-formative sinus. Immunohistochemical findings showed thatthe expression of CD31 was strongly positive in vascular-formative sinuses and some vascular-opening sinuses whileit was faint in blood-deficient sinuses, erythrophago-sinusesand some vascular-opening sinuses. It was almost negativein blood-abundant sinus and non-blood containing sinus.CONCLUSION: In the state of disease, the phenomenonof blood present in the lymph sinus is not uncommon. Bloodcould possibly enter into the lymph sinuses through thelymphaticovenous communications between the veins andthe sinuses in the node. Lymph circulation and the bloodcirculation could communicate with each other in the lymphnode sinuses. The skipping and distal lymphatic metastasisof gastric cancer may

    Enlarged lymph nodes in the mediastinum reflect neoplastic, infectious or other diseases. The classification of these nodes is crucial in the management of the patient. Currently, only invasive measures obtaining tissue samples reach satisfying specificity. Contrast-enhanced endoscopic ultrasound (EUS) may offer a non-invasive alternative. A total of 122 patients (age: 63 +/- 15 years, 92 males, 30 females) with enlarged mediastinal and/or paraaortic lymph nodes diagnosed by CT scan were included in the study. EUS-guided fine needle aspiration was performed and cytologic specimens were diagnosed as representing a malignant or benign process in case of Papanicolau IV and V, or Papanicolau I and II, respectively. Based on cytology results, the investigated lymph nodes were classified as neoplastic (n = 48) or non-neoplastic lymph nodes. Using the B-mode criteria the preliminary diagnosis was confirmed in 64 out of 74 benign lymph nodes (specificity 86%). Regarding malignant lymph nodes 33 of 48 were confirmed (sensitivity 68%). Using the advanced contrast-enhanced EUS criteria the diagnosis was confirmed in 68 of 74 benign lymph nodes (specificity 91%). However, in case of malignant lymph nodes the number of correct diagnoses dropped to 29 of 48 lymph nodes (sensitivity 60%). The contrast-enhanced EUS criteria to identify benign lymph nodes and node enlargement in malignant lymphoma do not differ. If those ten patients with malignant lymphoma are excluded, the sensitivity of the contrast enhanced EUS for malignant lymph nodes rises to 73%. Contrast-enhanced EUS improves the specificity in diagnosing benign lymph nodes as compared to B-mode EUS. It does not improve the correct identification of malignant lymph nodes and cannot replace EUS-guided fine-needle aspiration.

    Background and purpose: lymph node metastases and the number of positive lymph nodes are important prognostic factors for patients with cervical cancer. The most important route is the lateral drainage via the obturator to the internal and external iliac and common iliac area. The risk for common iliac lymph node metastases is increased in patients with positive pelvic or paraaortic lymph nodes. Positive common iliac lymph nodes are associated with a poorer prognosis than positive pelvic lymph nodes excluding common iliac group. For radiation planning in patients with cervical cancer, lymph node regions at high risk for metastases have to be encompassed. Usually, standard fields are used with the upper field border on the fourth/fifth lumbar vertebra. The authors evaluated whether standard fields are sufficient for encompassing the common iliac lymph nodes. Patients and methods: pretreatment computed tomographic (CT) images of 42 patients with cervical cancer were evaluated to locate the aortic bifurcation and the subsequent common iliac lymph drainage. Anatomy of the lymph drain was correlated with standard radiation portals. Results: in 17/42 patients (40%) the aortic bifurcation lay superior to the upper field border. In an additional nine patients (21%) the bifurcation was located on the level of the upper field border. In 26/42 patients (62%) standard radiation fields encompassed the common iliac lymph nodes insufficiently. Conclusion: common iliac lymph node metastases are found in up to 50% of patients with node-positive cervical cancer. The results of this study demonstrate an unsatisfactory coverage of the common iliac lymph drain by standard fields in most patients. Thus it is necessary to individualize the planning target volume and to include the whole common iliac vessels according to the patient's anatomy on radiation treatment planning CT in order to improve local control.

    Full Text Available Vitamin D deficiency is a major health problem in the Saudi population. A negative association between blood pressure and vitamin D level has been suggested in several clinical and epidemiological studies and evidence for an effect of vitamin D in lowering blood pressure was reported. These findings indicate that 1,25(OH2D3 deficiency may play a role in the pathogenesis of hypertension through its effect on the renin-angiotensin system. We are the first to investigate the correlation between blood pressure or renin concentration and vitamin D status in the Saudi population METHODS: we included 201 healthy Saudi premenopausal females (20-45 years old. Blood pressure was measured by a standardized method using an automated blood pressure monitor (BPTru. Fasting blood samples were collected from each participant after 20 minutes of rest in the seated position. Serum cholicalciferol, PTH and renin concentration were measured by sandwich chemiluminescence immunoassaymethod (DiaSorin, Italy. RESULTS: The analysis included 192 subjects who were normotensive (blood pressure <140/90 mmHg.  A total of  34% of women had a severe deficiency (vitamin D ≤ 12.5 nmol/L; 41% had moderate deficiency (vitamin D levels between 12.5 - 25 nmol/L;  23% had mild deficiency (vitamin D level ≥ 25 - < 50 nmol/L; and 2% had insufficiency (vitamin D level  ≥ 50 - ≤ 75 nmol/L. None had a sufficient level of ≥75 nmol/L.  The systolic blood pressure ranged from 79-130.5mmHg and the diastolic from 48.5-85.5 mmHg.  Both systolic and diastolic blood pressures were significantly higher in women that were in the lower 2 quartiles of vitamin D.  However, linear regression analysis adjusting for potential confounders showed that 25(OHD level was not a predictor of either systolic or diastolic blood pressures.  A negative correlation (although not significant was found between vitamin D level and plasma renin concentration in this study group. CONCLUSION: Vitamin D

    Full Text Available Low vitamin D levels have been described in obese individuals and in some autoimmune diseases, such as Systemic Lupus Erythematosus (SLE and primary antiphospholipid syndrome (pAPS. In particular, more than 50% of premenopausal women with pAPS have hypovitaminosis D. In this issue we report a case of an obese, premenopausal, and hypertensive woman with pseudo-Cushing syndrome, affected by deep venous thrombosis associated with pulmonary embolism after rib fracture who presented hypovitaminosis D. 7 years before, diagnosis of pAPS had been made after the detection of thrombocytopenia (present at a young age and arterial ischemia of a lower limb. For seven years she was treated with acetylsalicylic acid without complications. We found positive anti-dsDNA antibodies, a triple antiphospholipid antibodies (aPL positivity and levels of vitamin D < 4 µg/l. The case report arises some questions: is vitamin D deficiency due to obesity or APS? Is the positivity of anti-dsDNA indicative of progression to SLE? Is preventive therapy with hydroxychloroquine indicated? Does the high-risk aPL profile justify a high-intensity and life-long anticoagulation regimen?http://dx.doi.org/10.7175/cmi.v8i2.912

    Many observational studies linked vitamin D to cardiometabolic risks besides its pivotal role in musculoskeletal diseases, but evidence from trials is lacking and inconsistent. To determine whether Vitamin D supplementation in urban premenopausal women with vitamin D deficiency can improve cardiometabolic risks and health-related quality of life (HRQOL). A double-blind randomized controlled trial was conducted in Kuala Lumpur, Malaysia. A total of 192 vitamin D deficient (supplementation on HOMA-IR, serum lipid profiles and blood pressure (all p>0.05) between two groups. There was a small but significant improvement in HRQOL in the components of vitality (mean difference: 5.041; 95% CI: 0.709 to 9.374) and mental component score (mean difference: 2.951; 95% CI: 0.573 to 5.329) in the intervention group compared to placebo group. Large and less frequent dosage vitamin D supplementation was safe and effective in the achievement of vitamin D sufficiency. However, there was no improvement in measured cardiometabolic risk factors in premenopausal women. Conversely vitamin D supplementation improves some components of HRQOL.

    Ferritin levels have been associated with metabolic syndrome and insulin resistance. The aim of the present study was to evaluate the prediction of ferritin levels by variables related to cardiometabolic disease risk in a multivariate analysis. For this aim, 123 healthy women (72 premenopausal and 51 posmenopausal) were recruited. Data were collected through procedures of anthropometric measurements, questionnaires for personal/familial antecedents, and dietary intake (24-h recall), and biochemical determinations (ferritin, C reactive protein (CRP), glucose, insulin, and lipid profile) in blood serum samples obtained. Multiple linear regression analysis was used and variables with no normal distribution were log-transformed for this analysis. In premenopausal women, a model to explain log-ferritin levels was found with log-CRP levels, heart attack familial history, and waist circumference as independent predictors. Ferritin behaves as other cardiovascular markers in terms of prediction of its levels by documented predictors of cardiometabolic disease and related disorders. This is the first report of a relationship between heart attack familial history and ferr
