Objective
The aim of this study was to elucidate the clinicopathological significance and prognostic role of loss of claudin-1 in colorectal cancer (CRC).Methods
The correlations between claudin-1 expression and clinicopathological characteristics, including survival rates, were assessed using immunohistochemistry on 260 archival, paraffin-embedded CRC tissues. In addition, the correlations between cludin-1 and nuclear factor-kappa B (NF-κB), epithelial-mesenchymal transition markers and tumor-infiltrating lymphocytes were investigated.Results
Claudin-1 expression was markedly lost in 42.7% of the 260 CRCs analyzed. Loss of claudin-1 expression significantly correlated with larger tumor size, vascular invasion, higher pT stage, and high metastatic lymph node ratio. In addition, loss of claudin-1 expression significantly correlated with NF-κB activation (P?<?0.001), high SNAI (P?<?0.001), and low E-cadherin (P?<?0.001) expressions. Patients with high immunoscores showed significantly lower rates of claudin-1 expression loss (P?=?0.020). In detail, loss of claudin-1 expression were frequently found in CRCs low CD3- and CD8-positive lymphocytes. There were significant correlations between claudin-1 expression loss and poor overall and recurrence-free survivals (P?<?0.001 and P?<?0.001, respectively).Conclusion
Taken together, our results suggest that the loss of claudin-1 expression significantly correlates with aggressive tumor behaviors, high SNAI expression, lower immunoscore, and poor prognoses. 相似文献2.

Background
LincRNA-p21 is involved in the initiation and progression of many human diseases. We aimed to investigate the expression of LincRNA-p21 in different types of liver diseases.Methods
Serum from patients with primary liver diseases (chronic HBV or HCV infection, hepatitis B virus-related cirrhosis, hepatitis B virus-related HCC, non-HBV/HCV-related HCC, alcoholic liver disease) and HBV negative liver metastatic cancer and control healthy individuals was collected and serum lincRNA-p21 levels were determined by RT-qPCR. Clinicopathological characteristics of the patients were also recorded.Results
Serum lincRNA-p21 levels in patients with chronic HBV infection, hepatitis B cirrhosis, hepatitis B virus-related HCC, chronic hepatitis B virus infection, non-HBV/HCV-related HCC, and alcoholic liver disease were higher than those in the control individuals (P?<?0.001, P?<?0.001, P?<?0.001, P?<?0.001, P?<?0.001 and P?=?0.002, respectively). The serum lincRNA-p21 level was not significantly different between patients with HBV negative liver metastatic cancer and the normal control (P?=?0.80). LincRNA-p21 level was negatively correlated with HBV DNA (P?=?0.02), ALT (P?=?0.01) and AST (P?=?0.01) in patients with liver disease, but not correlated with gender (P?=?0.24), age (P?=?0.11) and AFP level (P?=?0.84). Serum lincRNA-p21 in hepatocellular carcinoma patients was higher than that in liver metastatic cancer patients (P?<?0.001).Conclusion
Serum lincRNA-p21 may serve as a potential biomarker for liver cell damage in patients with hepatitis virus infection, hepatitis B cirrhosis, HBV-related HCC and alcoholic liver disease. 相似文献3.

Introduction
Syndecan-1 is heparan sulfate proteoglycans (HSPGs) that is used as coreceptors for signaling of growth factors. The comprehensive effect of syndecan-1 is to augment receptor stimulation at little ligand concentrations.The goal of this research
is to study syndecan-1 expression in breast carcinoma and its value in predicting the prognosis in comparison to other clinicopathological parameters.Material &methods
immunohistochemistry study for syndecan-1 is done on 103 cases of invasive breast carcinoma. Its expression is assessed and correlated to other clinicopathological parameters and prognosis.Results
overexpression was significantly related to high histologic grade (p?=?0.001), large tumor size (p?=?0.043), HER2-positive status (p?=?0.001), and ER&PR-negative status (p?=?0.001). It was also have a negative impact on the overall survival (p=0.012) and disease free survival (p?=?0.009). Syndecan-1 expression showed weak positive correlation with Her 2 expression (Correlation Coefficient (co): 0.332, p?=?0.001).Conclusion
syndecan-1 is a good predictor of poor overall survival and recurrence/ metastasis free survival. It is associated with aggressive phenotype as HER2 enriched and Triple negative rather than luminal subtypes of breast carcinoma. So it can be added to the hormonal receptors and HER 2 assay in the routine management of invasive breast cancer after confirmation on a more larger study. 相似文献4.
Background
GPR110 is a member of the adhesion G protein-coupled receptor family, which has been identified as an oncogene in various cancers, including hepatocellular carcinoma, lung cancer, prostatic cancer and glioma. Whereas the expression and the clinical relevance of GPR110 in gastric cancer has not been investigated. The research purpose of this study was to explore the expression pattern of GPR110 and evaluate its clinical-pathological and prognostic value in gastric cancer.Methods
In this study, the expression of GPR110 was detected in 117 paired gastric cancer tissues and adjacent non-tumorous tissues by using qRT-PCR and immunohistochemical assays. Univariate Kaplan-Meier and multivariate Cox analysis were used to determine the prognostic value of GPR110 in GC.Results
We demonstrated that the mRNA and protein levels of GPR110 in GC tissues were overexpressed than the adjacent non-tumorous tissues. Furthermore, elevated GPR110 protein expression was correlated with decreased overall and recurrence-free survival (P?=?0.001 and P?=?0.000, respectively). Univariate and multivariate analysis indicated that GPR110 protein level may serve as an independent prognostic indicator for determining prognosis of GC patients.Conclusions
Our study revealed that high expression of GPR110 predicts the poor prognosis of GC patients, and GPTR110 may function as a potential biomarker for the diagnosis of GC. 相似文献5.

Objectives
The study’s goals were to characterize decisional conflict and preparedness for making the decision about having CPM among breast cancer patients considering CPM who do not carry cancer-predisposing mutation and to evaluate correlates of decisional conflict and preparedness.Methods
93 women considering CPM completed a survey of decisional conflict and preparedness for the CPM decision, knowledge, perceived risk, self-efficacy, reasons for CPM, input from others and discussion with the doctor about CPM, and cancer worry.Results
Between 8% and 27% of women endorsed elevated decisional conflict. Most women were satisfied with preparatory information that they were provided. Knowledge was low. Top reasons for choosing CPM were the desire for peace of mind, lowering the chance of another breast cancer, and improving survival.Conclusions
Decisional conflict is elevated in a subset of patients considering CPM. A more well-informed decision may be fostered by a comprehensive discussion about CPM with the patient’s clinician, fostering self-efficacy in managing cancer worry, and helping patients understand their motivations for CPM.Practice implications
Clinicians working with breast cancer patients considering CPM should discuss the CPM decision, foster self-efficacy in managing cancer worry, and help patients understand their motivations for the surgery. 相似文献6.

Objective
To develop a patient-centered informed consent and assessment tool written at a 6th grade-level that is multimodal, affordable, transportable, and readily modifiable for protocol updates.Methods
This quality improvement initiative was performed in two phases on an actively-recruiting study at a pediatric diabetes clinic. In phase I, 38 volunteers underwent the standard-paper consent process, a comprehension assessment and provided feedback. Using feedback and the structure of the Plan-Do-Study-Act cycle a multimodal consent and assessment were developed. In phase II, volunteers were randomized to the standard (n?=?25) or the multimodal consent (n?=?25) and all completed the same comprehension assessment via touch-screen tablet. Primary outcomes were comparison of the individual and total comprehension assessment scores.Results
Total comprehension scores were higher in the multimodal versus the standard consent group (p?<? 0.001) and on the elements of benefits (p?<? 0.001), risks (p?<? 0.001), volunteerism (p?<? 0.012), results (p?<? 0.001), confidentiality (p?<? 0.004) and privacy (p < 0.001).Conclusion
A multimodal consent and assessment presented sequentially on a touch-screen tablet were patient-centered enhancements to standard consent.Practice implications
Multimodal standardization of delivery with improved readability may strengthen the informed consent process. 相似文献7.

Objective
To assess women’s attitudes and preferences related to recent changes in cervical cancer screening guidelines.Methods
We distributed 380 surveys in three University based and Community clinics. Study participants anonymously completed surveys, which included questions related to demographics, cervical cancer, screening practices, risk perception and attitudes towards changing practices.Results
315 women agreed to participate (83%). 60% (185/310) of participants had some college education or higher and 12% (36/305) worked in the medical field. On average, participants answered 4.1 (SD?=?1.3) of the 8 knowledge questions correctly. Knowledge scores significantly increased with education level (Kruskal-Wallis test p-value?<?0.001). The majority (72%, n?=?228) reported that they should be screened annually, and that screening should be initiated with the onset of sexual activity (63%, n?=?197). Participants that were more knowledgeable of current screening practices were more comfortable extending screening intervals (Kruskal-Wallis test p?<?0.001).Conclusion
Even among a relatively highly educated population of women, participants had limited knowledge of cervical cancer and current screening guidelines. Many participants reported discomfort with less frequent screening intervals.Practice implications
This study supports the need for improvement in cervical cancer prevention education especially with regards to the new screening guidelines. 相似文献8.

Objective
Recently, a low frequency of de novo T790M mutations existing in tumor tissues before TKIs therapy has been reported. However, the origin of T790M and its impact on clinical outcomes is still being debated. This study aimed to use highly sensitive methods to detect T790M before and after TKIs therapy and investigated the correlation of T790M with clinical prognosis.Patients and methods
Matched tumor samples before and after treatment were collected from 61 lung adenocarcinoma (LAC) patients in Beijing Chest Hospital between June 2014 to October 2017. Presence of the T790M mutation was simultaneously detected using amplification refractory mutation system-PCR (ARMS-PCR) assay and droplet digital PCR (ddPCR) assay.Results
Of the 61 enrolled patients, 46 were candidates for and received TKIs treatment based on their EGFR mutation status. When these samples were assayed, ddPCR identified significantly more T790M mutations than ARMS-PCR (before TKIs treatment: 19.6% (9/46) vs. 2.2% (1/46), P?=?0.040; after TKIs treatment: 78.3% (36/46) vs. 50% (23/46), P?<?0.001, respectively). Patients with first-line TKIs treatment harboring de novo T790M mutations showed a shorter PFS compared to those without de novo T790M mutations (median, 7.0 months vs. 11.7 months, p?=?0.013). In multivariate analyses, de novo T790M mutation was an independent predictor of PFS in EGFR-mutant patients who received TKIs treatment (p?=?0.031, HR 0.310, 95% CI: 0.107-0.900).Conclusion
The ddPCR assay is an ultra-sensitive method to detect a minor amount of de novo T790M mutations in tumor samples. The de novo T790M mutation is a relatively unfavorable prognosis factor for patients receiving first-line TKIs treatment. 相似文献9.

Background
Studies have shown that 30–50% of non-small cell lung cancer (NSCLC) patients develop brain metastasis (BM). Since BM shortens overall survival and decreases the quality of life, early detection and treatment of BM are vital. While data are available for clinical risk factors of NSCLC with BM, histopathological factors are not well understood. Therefore, we evaluated the histopathological related factors which will help early detection and selection of effective treatment options.Materials and methods
A total of 117 surgical lung specimens diagnosed as NSCLC with BM were included as a study group. We included 237 cases without BM as a control group. One pathologist reviewed H&E slides and analyzed the histopathologic factors of all cases.Results
In pulmonary adenocarcinoma, vascular invasion, N stage, micropapillary pattern and necrosis were significantly associated with BM in multivariate analysis (vascular invasion, p?=?0.009; micropapillary pattern, p?=?0.024; others, p?<?0.001). Tumor with extensive necrosis had higher hazard ratio and shorter time to BM (p?<?0.001).Conclusion
Our findings suggest that necrosis is a new predictive factor of BM in pulmonary adenocarcinoma. Short term follow-up is needed especially when extensive necrosis is present. 相似文献10.

Purpose
To screen novel candidate biomarkers in primary colorectal cancer (CRC), and indentify their clinical valuation in progress of colorectal cancer.Methods
By using antibody microarray, 274 target proteins in tissue samples from primary colorectal cancer patients were detected. Among differently expressed proteins in CRC tissues, As promising candidate biomarker, RANTES/CCL5 was validated by enzyme-linked immunosorbentassay and immunohistochemistry (IHC), and the clinical significance of CCL5 was analyzed.Results
Totally, 25 differentially expressed proteins were indentified between colorectal cancers and matched normal mucosa. CCL5 expression was significantly associated with adverse pathological progress, apt to lymph node metastasis and higher T stage.Conclusions
CCL5 may contribute to promoting tumor growth, and CCL5 is a promising target that may help in understanding the pathogenesis of CRC. 相似文献12.

Objective
Information overload can negatively impact positive health behaviors such as cancer screening. The 8-item Cancer Information Overload (CIO) scale appears to be the only validated measure of health-related information overload. The present study assesses the validity of the CIO scale when modified for use in patients with atrial fibrillation (AF) residing in Australia.Methods
We conducted a secondary analysis of data from a study of adult Australian patients with AF (N?=?386) in which a modified version of the CIO scale was used. In the present study, we examined the construct (convergent and divergent) validity and performed an exploratory factor analysis for the modified scale.Results
All items on the modified-CIO scale appear to load onto a single factor. As predicted, higher education levels (rs=-.24, p?<?.001) and higher oral anticoagulant knowledge (rs=-.17, p?=?.001) were significantly associated with lower modified-CIO scores; no other demographic characteristics were significantly associated with CIO scores.Conclusion
When adapted to the AF context, the modified-CIO scale appears to be a valid measure of information overload.Practice Implications
A valid scale is required to measure information overload accurately. Knowledge of the interplay between information overload and various health behaviors help focus future efforts to support patient empowerment. 相似文献14.

Background
The miR-129-5p has been reported to be aberrant expression and exert vital roles in tumor progression of various malignancies. However, the effects on EMT in gastric cancer and its precise molecular mechanism in gastric cancer remain unclear.Methods and materials
RT-qPCR was performed to evaluate the expression level of miR-129-5p and HMGB1 in cell lines. Cell proliferation was detected via CCK-8. The epithelial mesenchymal transition (EMT) related proteins and the expression of HMGB1 were detected by western blot analysis. Luciferase assays were used to validate binding seeds between miR-129-5p and HMGB1.Results
miR-129-5p was downregulated in gastric cancer cells compared with GES-1. At the same time EMT was promoted in gastric cancer cells compared to GES-1. Overexpression of miR-129-5p inhibited EMT and proliferation. MiR-129-5p negatively and directly targeted HMGB1. HMGB1 was upregulated in gastric cancer cells and HMGB1 knocked-down inhibited EMT and cell proliferation.Conclusion
Taken together, upregulation of miR-129-5p associated with gastric cancer proliferation and EMT, and serves as a potential diagnostic and therapeutic target via miR-129-5p/HMGB1 pathway in gastric cancer. 相似文献15.

Objective
To examine breast cancer patients’ reasons to seek a second opinion (SO) and the underlying variables. To find out more about the outcome of the SO, the perceived helpfulness and the effect on the physician-patient relationship.Methods
In 2017, 4626 newly diagnosed breast cancer patients from 86 hospitals in Germany completed a postoperative mail survey (response rate?=?89.04%). Data from 419 SO-seeking patients was obtained and analyzed by conducting logistic regression and non-parametric group comparisons.Results
Reasons to seek an SO were mostly unrelated to the physician-patient relationship. Reasons related to the physician-patient-relationship were associated with a lower education level. The SO mostly (72.2%) equaled the first opinion. A different treatment plan recommendation (25%) reportedly affected the patients’ relationship with their primary physician. Patients who received a different diagnosis reported more fear of progression. Most patients found the SO helpful.Conclusion
The reasons to seek an SO are primarily unrelated to the physician-patient relationship. However, less educated patients seem to have different reasons to seek an SO. These reasons were reportedly associated with the physician-patient relationship.Practice implications
Physicians may need to explicitly ascertain the patient’s needs within the physician-patient communication to avoid inequalities based on patient education. 相似文献16.

Objectives
The aim of this study was to investigate the link between perceived dimensions of patient centred care and the satisfaction of adolescents and young adults within the UK, USA, Australian, Italian, and Chinese healthcare systems.Methods
One thousand and thirty-four participants (212 from China,206 from Australia,208 from UK, 202 from USA, and 206 from Italy) answered a self-report questionnaire assessing the perceived dimensions of patient centred care. Factor analysis (PFA) was conducted on the data to identify relevant dimensions. One-way ANOVAs were run to identify differences between country samples related to perceived dimensions of patient centredness, and a multi-level multiple regression model was computed to assess the link between satisfaction and dimensions of patient centred care.Results
Countries’ mean scores on ‘Satisfaction with Care’ (PF1) and on ‘Psychosocial Context’ (PF2) were statistically significant by inspecting the ANOVAs (p?<?.05). Satisfaction with care was predicted by PF2 and clinical utilization.Conclusion
An online survey collected meaningful data on perceptions of healthcare received by respondents from five countries. This initial international study highlights important associations worthy of closer investigation.Practice implications
Healthcare providers should assess comprehensively the psychosocial context of young patients during consultations. 相似文献18.

Background
The identification of the M-type phospholipase A2 receptor (PLA2R) is a breakthrough recognized as a major target for adults with idiopathic membranous nephropathy (IMN). However, the role PLA2R played in pediatric patients with IMN, particularly in Chinese, has yet to be determined.Methods
This retrospective study included 187 adult patients and 38 pediatric patients aged 17 years or younger with biopsy proved IMN. The pediatric cohort consisted of 27 children aged from 1 to 12 years and 11 children aged from 13 to 17. Glomerular expression of PLA2R was analyzed in stored, formalin-fixed, paraffin-embedded kidney biopsy sections.Results
PLA2R staining in glomerular deposits was observed in 82.7% and 42.1% of adult and pediatric patients with IMN, respectively. The PLA2R-positive staining patients with IMN presented with more severe clinical features than PLA2R-negative staining patients in both adult and pediatric cohorts. When compared to the young children patients with IMN, the adolescents exhibited a higher positive rate of PLA2R staining (81.8% versus 25.9%), similar to the adult patients.Conclusion
The clinical features and prevalence of PLA2R positive staining in adolescent patients with IMN were similar to adult patients, suggesting that they probably have a close etiology and pathogenesis. However, most of the young children patients with IMN were PLA2R negative staining, suggesting a different underlying etiology. 相似文献19.

Background
This work was designed to determine the relationship between hypoxia-inducible protein carbonic anhydrase IX (CA IX) and pro-inflammatory enzyme cyclooxygenase-2 (COX-2) in patients with colorectal cancer (CRC).Methods
We examined CA IX and COX-2 expression in CRC tissues by immunohistochemical staining of 111 samples. We evaluated the correlation between the expression of these proteins and their correlation with the clinico-morphological parameters of CRC.Results
CA IX was detected in 89 of 111 cases (80.2%). We predominantly observed membrane staining (70.3%) and a strong immunoreaction intensity (58.6%). The percentage of labeled cells in malignant lesions was less than 25% in 12.6% of cases, less than 50% in 15.3% of cases and more than 50% in 52.3% of CRC cases. The COX-2 protein was expressed in 94 of 111 cases (84.7%). We noticed only cytoplasmic localization, while immunoreaction intensity was predominantly strong (47.8%). The percentage of COX-2 positive cells was less than 25% only in 2.7% of the cases, less than 50% in 21.6% of the cases and more than 50% in 60.4% of the cases. No statistically significant correlations were observed between CA IX expression and clinico-morphological parameters. COX-2 expression was only significantly correlated with the tumor stage. Statistical analysis confirmed a significant correlation between the parameters of expression of the CA IX and COX-2 proteins.Conclusion
CA IX/COX-2 interplay can promote hypoxia survival and the invasion of tumor cells. These proteins may represent independent prognostic factors of CRC. 相似文献20.
