GLI1 and PTTG1 expression in colorectal carcinoma patients undergoing radical surgery and their correlation with lymph node metastasis

BACKGROUND Few studies have investigated the expression of GLI1 and PTTG1 in patients undergoing radical surgery for colorectal carcinoma(CRC)and their association with lymph node metastasis(LNM).Therefore,more relevant studies and analyses need to be conducted.AIM To explore GLI1 and PTTG1 expression in patients undergoing radical surgery for CRC and their correlation with LNM.METHODS This study selected 103 patients with CRC admitted to our hospital between April 2020 and April 2023.Sample specimens of CRC and adjacent tissues were collected to determine the positive rates and expression levels of GLI1 and PTTG1.The correlation of the two genes with patients’clinicopathological data(e.g.,LNM)was explored,and differences in GLI1 and PTTG1 expression between patients with LNM and those without were analyzed.Receiver operating characteristic(ROC)curves were plotted to evaluate the predictive potential of the two genes for LNM in patients with CRC.RESULTS Significantly higher positive rates and expression levels of GLI1 and PTTG1 wereobserved in CRC tissue samples compared with adjacent tissues.GLI1 and PTTG1 were strongly linked to LNM in patients undergoing radical surgery for CRC,with higher GLI1 and PTTG1 levels found in patients with LNM than in those without.The areas under the ROC curve of GLI1 and PTTG1 in assessing LNM in patients with CRC were 0.824 and 0.811,respectively.CONCLUSION GLI1 and PTTG1 expression was upregulated in patients undergoing radical surgery for CRC and are significantly related to LNM in these patients.Moreover,high GLI1 and PTTG1 expression can indicate LNM in patients with CRC undergoing radical surgery.The expression of both genes has certain diagnostic and therapeutic significance.

STAT-3 correlates with lymph node metastasis and cell survival in gastric cancer

AIM:To investigate the correlation between gastric cancer growth and signal transducer and activator of transcription-3(STAT3) expression.METHODS:We assessed the expressions of STAT3,phosphor-STAT3(pSTAT3),suppressor of cytokine signaling-1(SOCS-1),survivin and Bcl-2 in gastric cancer patients after gastrectomy by immunohistochemical method.In addition,in situ hybridization was used to further demonstrate the mRNA expression of STAT3 in gastric cancer.RESULTS:With the univariate analysis,expressions of STAT3,pSTAT3,SOCS-1,survivin and Bcl-2,the size of primary tumor and the lymph node metastasis were found to be associated with the overall survival(OS) of gastric cancer patients.However,only pSTAT3 expression and the lymph node metastasis were identified as the independent factors of OS of gastric cancer with multivariate analysis.STAT3 expression was correlated with the lymph node metastasis.There were positive correlations between expressions of STAT3,survivin,Bcl-2 and pSTAT3 in gastric cancer,whereas there was negative correlation between STAT3 expression and SOCS-1 expression in gastric cancer.CONCLUSION:STAT3 can transform into pSTAT3 to promote the survival and inhibit the apoptosis of gastric cancer cells.SOCS-1 might be the valid molecular antagonist to inhibit the STAT3 expression in gastric cancer.

CXCR4/SDF-1 axis is involved in lymph node metastasis of gastric carcinoma

AIM:To investigate the role of CXC chemokine receptor-4 (CXCR4) and stromal cell-derived factor-1 (SDF-1) in lymph node metastasis of gastric carcinoma.METHODS:In 40 cases of gastric cancer,expression of CXCR4 mRNA in cancer and normal mucous membrane and SDF-1 mRNA in lymph nodes around the stomach was detected using quantitative polymerase chain reaction (PCR) (TaqMan) and immunohistochemistric assay.SGC-7901 and MGC80-3 cancer cells were used to investigate the effect of SDF-1 on cell proliferation and migration.RESULTS:Quantitative reverse transcription PCR and immunohistochemistry revealed that the expression level of CXCR4 in gastric cancer was significantly higher than that in normal mucous membrane (1.6244 ± 1.3801 vs 1.0715 ± 0.5243,P < 0.05).The expression level of CXCR4 mRNA in gastric cancer with lymph node metastasis was also significantly higher than that without lymph node metastasis (0.823 ± 0.551 vs 0.392 ± 0.338,P < 0.05).CXCR4 expression was significantly related to poorly differentiated,high tumor stage and lymph node metastasis.Significant differences in the expression level of SDF-1 mRNA were found between lymph nodes in metastatic gastric cancer and normal nodes (0.5432 ± 0.4907 vs 0.2640 ± 0.2601,P < 0.05).The positive expression of SDF-1 mRNA in lymph nodes of metastatic gastric cancer was consistent with the positive expression of CXCR4 mRNA in gastric cancer (r=0.776,P < 0.01).Additionally,human gastric cancer cell lines expressed CXCR4 and showed vigorous proliferation and migratory responses to SDF-1.AMD3100 (a specific CXCR4 antagonist) was also found to effectively reduce the migration of gastric cancer cells.CONCLUSION:The CXCR4/SDF-1 axis is involved in the lymph node metastasis of gastric cancer.CXCR4 is considered as a potential therapeutic target in the treatment of gastric cancer.

Prognostic value of lymph node metastasis in patients with T1-stage colorectal cancer from multiple centers in China

AIM To explore the features and prognostic value of lymph node metastasis in patients with T1-stage colorectal cancer(CRC).METHODS In all,321 cases of T1-stage CRC were selected from 10132 patients with CRC who received surgical therapy in six large-scale hospitals in China and were retrospectively analyzed. Univariate and multivariate analyses were performed to analyze the risk factors for lymphatic metastasis. A survival analysis was then performed to analyze the prognostic value of lymph node metastasis.RESULTS The occurrence rate of T1 stage was 3.17%(321/10132);of these patients,the lymph node metastasis rate was 8.41%(27/321),and the non-lymph node metastasis rate was 91.59%(294/321). Univariate analysis showed that preoperative serum CEA,preoperative serum CA199,preoperative serum CA724,vascular invasion,and degree of differentiation were associated with lymph node metastasis in T1-stage CRC(P < 0.05 for all). Multivariate analysis indicated that preoperative serum CA724,vascular invasion,and degree of differentiation were closely related to lymph node metastasis(P < 0.05 for all). Log-rank survival analysis showed that age,preoperative serum CEA,preoperative serum CA199,vascular invasion,degree of differentiation,and lymph node metastasis(χ2 = 24.180,P < 0.001) were predictors of 5-year overall survival(OS)(P < 0.05 for all). COX regression analysis demonstrated that preoperative serum CA199 and lymph node metastasis(HR = 5.117;P < 0.05;95%CI: 0.058-0.815) were independent prognostic indicators of 5-year OS in patients with T1-stage CRC(P < 0.05 for both). CONCLUSION The morbidity of T1-stage CRC was 3.17% for all CRC cases. Preoperative serum CA724,vascular invasion,and degree of differentiation are independent risk factors for lymph node metastasis. Lymph node metastasis is an independent prognostic factor for OS in patients with T1-stage CRC.

CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric carcinoma

AIM To investigate the role of CXC chemokine receptor (CXCR)-7 and CXCL12 in lymph node and liver metastasis of gastric carcinoma. METHODS In 160 cases of gastric cancer, the expression of CXCR7 and CXCL12 in tumor and matched tumoradjacent non-cancer tissues, in the lymph nodes around the stomach and in the liver was detected using immunohistochemistry to analyze the relationship between CXCR7/CXCL12 expression and clinicopathological features and to determine whether CXCR7 and CXCL12 constitute a biological axis to promote lymph node and liver metastasis of gastric cancer. Furthermore, the CXCR7 gene was silenced and overexpressed in human gastric cancer SGC-7901 cells, and cell proliferation, migration and invasiveness were measured by the MTT, wound healing and Transwell assays, respectively. RESULTS CXCR7 expression was up-regulated in gastric cancer tissues (P = 0.011). CXCR7/CXCL12 expression was significantly related to high tumor stage and lymph node (r = 0.338, P = 0.000) and liver metastasis (r = 0.629, P = 0.000). The expression of CXCL12 in lymph node and liver metastasis was higher than that in primary gastric cancer tissues (chi(2) = 6.669, P = 0.010; chi(2) = 25379, P = 0.000), and the expression of CXCL12 in lymph node and liver metastasis of gastric cancer was consistent with the positive expression of CXCR7 in primary gastric cancer (r = 0.338, P = 0.000; r = 0.629, P = 0.000). Overexpression of the CXCR7 gene promoted cell proliferation, migration and invasion. Silencing of the CXCR7 gene suppressed SGC-7901 cell proliferation, migration and invasion. Human gastric cancer cell lines expressed CXCR7 and showed vigorous proliferation and migratory responses to CXCL12. CONCLUSION The CXCR7/CXCL12 axis is involved in lymph node and liver metastasis of gastric cancer. CXCR7 is considered a potential therapeutic target for the treatment of gastric cancer.

Correlation between mitochondrial TRAP-1 expression and lymph node metastasis in colorectal cancer

AIM： To evaluate the effect of mitochondrial tumor ne- crosis factor receptor-associated protein-1 （TRAP-l） on the lymph node metastasis （LNM） in Chinese colorectal cancer （CRC） patients, and develop potential LNM- associated biomarkers for CRC using quantitative real- time polymerase chain reaction （RT-PCR） analysis. METHODS： Differences in mitochondrial TRAP-1 gene expression between primary CRC with LNM （LNM CRC） and without LNM （non-LNM CRC） were assessed in 96 Chinese colorectal carcinoma samples using quantita- tive RT-PCR analysis, Western blotting, and confirmed with immunohistochemical assay. The relationship between clinicopathological parameters and potential diaclnostic biomarkers was also examined.RESULTS： TRAP-1 was significantly upregulated in LNM CRC compared with non-LNM CRC, which was confirmed by RT-PCR, Western blotting and immuno- histochemical assay. The expression of TRAP-1 in two different metastatic potential human colorectal cancer cell lines, LoVo and HT29, was analyzed with Western blotting. The expression level of TRAP-1 was dramati- cally higher in LoVo than in HT29. Overexpression of TRAP-1 was significantly associated with LNM （90.2% in LNM group vs 22% in non-LNM group, P 〈 0.001）, the advanced tumor node metastasis stage （89.1% in LNM group vs 26.9% in non-LNM group, P 〈 0.001）, the increased 5-year recurrence rate （82.7% in LNM group vs 22.6% in non-LNM group, P 〈 0.001） and the decreased 5-year overall survival rate （48.4% in LNM vs 83.2% in non-LNM group, P 〈 0.001）. Univariate and multivariate analyses indicated that TRAP-1 expression was an independent prognostic factor for recurrence and survival of CRC patients （Hazard ratio of 2.445 in recurrence, P = 0.017; 2.867 in survival, P = 0.028）. CONCLUSION： Mitochondria TRAP-1 affects the lymph node metastasis in CRC, and may be a potential bio- marker for LNM and a prognostic factor in CRC. Over- expression of TRAP-1 is a predictive factor for the poor outcome of colorectal cancer patients. 2012 Baishideng. All rights reserved

Risk factors for lymph node metastasis in T1 esophageal squamous cell carcinoma:A systematic review and meta-analysis

BACKGROUND Lymph node metastasis(LNM)affects the application and outcomes of endoscopic resection in T1 esophageal squamous cell carcinoma(ESCC).However,reports of the risk factors for LNM have been controversial.AIM To evaluate risk factors for LNM in T1 ESCC.METHODS We searched Embase,PubMed and Cochrane Library to select studies related to LNM in patients with T1 ESCC.Included studies were divided into LNM and non-LNM groups.We performed a meta-analysis to examine the relationship between LNM and clinicopathologic features.Odds ratio(OR),mean differences and 95%confidence interval(CI)were assessed using a fixed-effects or randomeffects model.RESULTS Seventeen studies involving a total of 3775 patients with T1 ESCC met the inclusion criteria.After excluding studies with heterogeneity based on influence analysis,tumor size(OR=1.93,95%CI=1.49-2.50,P<0.001),tumor location(OR=1.46,95%CI=1.17-1.82,P<0.001),macroscopic type(OR=3.17,95%CI=2.33-4.31,P<0.001),T1 substage(OR=6.28,95%CI=4.93-8.00,P<0.001),differentiation(OR=2.11,95%CI=1.64-2.72,P<0.001)and lymphovascular invasion(OR=5.86,95%CI=4.60-7.48,P<0.001)were found to be significantly associated with LNM.Conversely,sex,age and infiltrative growth pattern were not identified as risk factors for LNM.CONCLUSION A tumor size>2 cm,lower location,nonflat macroscopic type,T1b stage,poor differentiation and lymphovascular invasion were associated with LNM in patients with T1 ESCC.

T1 rectal mucinous adenocarcinoma with bilateral enlarged lateral lymph nodes and unilateral metastasis:A case report

BACKGROUND There are a few cases of lateral lymph node(LLN)metastasis(LLNM)of T1 rectal cancer.Moreover,LLNM is easily missed,especially in patients with early-stage rectal cancer.To our knowledge,the possibility of bilateral LLNM before surgery has not been reported in previous studies.CASE SUMMARY A 36-year-old woman underwent endoscopic submucosal dissection at a local hospital owing to a clinical diagnosis of a rectal polyp.The pathology report showed a diagnosis of T1 rectal mucinous adenocarcinoma.She was considered to have bilateral LLNM after the examination at our hospital.Laparoscopic total mesorectal excision plus bilateral LLN dissection was performed and the pathological outcomes indicated unilateral LLNM.The patient received longcourse adjuvant chemoradiotherapy with no recurrence or metastasis observed during the 1-year follow-up period.CONCLUSION T1 rectal cancer could lead to LLNM and possibly,bilateral LLNM.Therefore,adequate clinical evaluation is essential for these patients.

THE MIB-1 PROLIFERATION INDEX AND MICROVESSEL COUNT IN EARLY GASTRIC CANCER:ASSOCIATION WITH LYMPH NODE METASTASIS

Objective Tumors with accelerated growth or high malignancy are thought to undergo active angio- genesis. Whereas by far, there is few study concerning the combination of MIB-1 proliferation index (MIB-1 PI) and tumor angiogenesis in carcinomas to show their significance in relate to clinicopathological parameters. In the present study, we evaluated the significance or MIB-1 PI and angiogenesis in early stage of gastric cancer. Our focus was es- pecially on the combination of MIB-1 PI and angiogenesis in relate to lymph node metastasis. Method Specimens from 95 patients with early gastric cancer were studied by means or immunohistochemistry using monoclonal MIB-1 and factor Ⅷ related antigen antibodies. Results The mean MIB-1 PI and microvessel count were 22.9% and 34.7, respectively. The MIB-1 PI did not correlate with microvessel count. Both correlated with depth of tumor invasion, lymphatic vessel invasion and lymph node metastasis. Multivarlate analysis showed that combined high MIB-1 PI/hy- pervascularity, as well as lymphatic vessel invasion and tumor size were independent factors that impact on lymph node metastasis. Conclusion A combination of the high MIB-1 PI/hypervascularity is a factor that related to lymph node metastasis in early gastric cancer.

Assessment of programmed death-ligand 1 expression in primary tumors and paired lymph node metastases of gastric adenocarcinoma

BACKGROUND Anti-programmed death-1/programmed death-ligand 1(PD-1/PD-L1)immuno-therapy has demonstrated promising results on gastric cancer(GC).However,PD-L1 can express differently between metastatic sites and primary tumors(PT).AIM To compare PD-L1 status in PT and matched lymph node metastases(LNM)of GC patients and to determine the correlation between the PD-L1 status and clinicopathological characteristics.METHODS We retrospectively reviewed 284 GC patients who underwent D2-gastrectomy.PD-L1 was evaluated by immunohistochemistry(clone SP142)using the com-bined positive score.All PD-L1+PT staged as pN+were also tested for PD-L1 expression in their LNM.PD-L1(-)GC with pN+served as the comparison group.RESULTS Among 284 GC patients included,45 had PD-L1+PT and 24 of them had pN+.For comparison,44 PD-L1(-)cases with pN+were included(sample loss of 4 cases).Of the PD-L1+PT,54.2%(13/24 cases)were also PD-L1+in the LNM.Regarding PD-L1(-)PT,9.1%(4/44)had PD-L1+in the LNM.The agreement between PT and LNM had a kappa value of 0.483.Larger tumor size and moderate/severe peritumoral inflammatory response were associated with PD-L1 positivity in both sites.There was no statistical difference in overall survival for PT and LNM according to the PD-L1 status(P=0.166 and P=0.837,respectively).CONCLUSION Intra-patient heterogeneity in PD-L1 expression was observed between the PT and matched LNM.This disagreement in PD-L1 status may emphasize the importance of considering different tumor sites for analyses to select patients for immunotherapy.

Nomogram based on multimodal magnetic resonance combined with B7-H3mRNA for preoperative lymph node prediction in esophagus cancer

Accurate preoperative prediction of lymph node metastasis(LNM)in esophageal cancer(EC)patients is of crucial clinical significance for treatment planning and prognosis.AIM To develop a clinical radiomics nomogram that can predict the preoperative lymph node(LN)status in EC patients.METHODS A total of 32 EC patients confirmed by clinical pathology(who underwent surgical treatment)were included.Real-time fluorescent quantitative reverse transcription-polymerase chain reaction was used to detect the expression of B7-H3 mRNA in EC tissue obtained during preoperative gastroscopy,and its correlation with LNM was analyzed.Radiomics features were extracted from multi-modal magnetic resonance imaging of EC using Pyradiomics in Python.Feature extraction,data dimensionality reduction,and feature selection were performed using XGBoost model and leave-one-out cross-validation.Multivariable logistic regression analysis was used to establish the prediction model,which included radiomics features,LN status from computed tomography(CT)reports,and B7-H3 mRNA expression,represented by a radiomics nomogram.Receiver operating characteristic area under the curve(AUC)and decision curve analysis(DCA)were used to evaluate the predictive performance and clinical application value of the model.RESULTS The relative expression of B7-H3 mRNA in EC patients with LNM was higher than in those without metastasis,and the difference was statistically significant(P<0.05).The AUC value in the receiver operating characteristic(ROC)curve was 0.718(95%CI:0.528-0.907),with a sensitivity of 0.733 and specificity of 0.706,indicating good diagnostic performance.The individualized clinical prediction nomogram included radiomics features,LN status from CT reports,and B7-H3 mRNA expression.The ROC curve demonstrated good diagnostic value,with an AUC value of 0.765(95%CI:0.598-0.931),sensitivity of 0.800,and specificity of 0.706.DCA indicated the practical value of the radiomics nomogram in clinical practice.CONCLUSION This study developed a radiomics nomogram that includes radiomics features,LN status from CT reports,and B7-H3 mRNA expression,enabling convenient preoperative individualized prediction of LNM in EC patients.

Anlotinib suppresses lymphangiogenesis and lymphatic metastasis in lung adenocarcinoma through a process potentially involving VEGFR-3 signaling

Objective:Lymphatic metastasis is one of the leading causes of malignancy dispersion in various types of cancer.However,few anti-lymphangiogenic drugs have been approved for clinical use to date.Therefore,new therapies to block lymphangiogenesis are urgently required.Methods:Immunohistochemistry,immunofluorescence,Western blot,migration assays,and lymphangiogenesis and lymphatic metastasis assays were used.Results:Anlotinib,a receptor tyrosine kinase inhibitor,suppressed the rate of new metastatic lesions(31.82%in the placebo arm and 18.18%in the anlotinib arm)in patients with advanced lung adenocarcinoma who were enrolled in our ALTER-0303 study.D2-40+-lymphatic vessel density was strongly correlated with disease stage,metastasis,and poor prognosis in 144 Chinese patients with lung adenocarcinoma.In mice bearing A549EGFP tumors,tumor lymphatic vessel density,tumor cell migration to lymph nodes,and the number of distant metastatic lesions were lower in the anlotinib group than in the controls.Anlotinib inhibited the growth and migration of human lymphatic endothelial cells(hLECs)and lymphangiogenesisin vitro andin vivo.Treatment of hLECs with anlotinib downregulated phosphorylated vascular endothelial growth factor receptor 3(VEGFR-3).Conclusions:Anlotinib inhibits lymphangiogenesis and lymphatic metastasis,probably through inactivating VEGFR-3 phosphorylation.The results indicate that anlotinib may be beneficial for treatment in avoiding lymphangiogenesis and distant lymphatic metastasis in lung adenocarcinoma.(Trial registration:ALTER0303;NCT02388919;March 17,2015.)

Risk of lymph node metastases in patients with T1b oesophageal adenocarcinoma: A retrospective single centre experience

AIM To assess clinical outcomes for submucosal (T1b) oesophageal adenocarcinoma (OAC) patients managed with either surgery or endoscopic eradication therapy.METHODS Patients found to have T1b OAC following endoscopic resection between January 2008 to February 2016 at University College London Hospital were retrospectively analysed. Patients were split into low-risk and high-risk groups according to established histopathological criteria and were then further categorised according to whether they underwent surgical resection or conservative management. Study outcomes include the presence of lymphnode metastases, disease-specific mortality and overall survival. RESULTS A total of 60 patients were included; 22 patients were surgically managed (1 low-risk and 21 high-risk patients) whilst 38 patients were treated conservatively (12 low-risk and 26 high-risk). Overall, lymph node metastases (LNM) were detected in 10 patients (17%); six of these patients had undergone conservative management and LNM were detected at a median of 4 mo after endoscopic mucosal resection (EMR). All LNM occurred in patients with highrisk lesions and this represented 21% of the total high-risk lesions. Importantly, there was no statistically significant difference in tumor-related deaths between those treated surgically or conservatively (P = 0.636) and disease-specific survival time was also comparable between the two treatment strategies (P = 0.376).CONCLUSION T1b tumours without histopathological high-risk markers of LNM can be treated endoscopically with good outcomes. In selected patients, endoscopic therapy may be appropriate for high-risk lesions.

宫颈癌患者淋巴结转移的危险因素分析及血清TFF3、AIF-1、S100-A11、DKK1预测价值分析

目的 探讨宫颈癌患者淋巴结转移的危险因素分析及血清三叶因子3(trefoil factor 3,TFF3)、同种异体移植物炎性因子-1(allograft inflammatory factor-1,AIF-1)、S100钙结合蛋白-A11(S100 calcium-binding protein-A11,S100-A11)、Wnt通路抑制因子Dickkopf-1(Wnt pathway inhibitor Dickkopf-1,DKK1)的预测价值。方法 选择2021年1月—2023年1月本院收治的71例宫颈癌患者作为研究对象,根据患者有无盆腔淋巴结转移分为淋巴结转移阳性组(28例)和淋巴结转移阴性组(43例)两组。收集两组患者临床病理特征,并检测血清TFF3、AIF-1、S100-A11、DKK1水平。结果 单因素分析显示,FIGO分期、宫旁浸润、肌层浸润、血清TFF3、S100-A11、DKK1是患者发生宫颈癌淋巴结转移的影响因素(P<0.05)。与年龄、分化程度、肿瘤大小、组织学类型、脉管浸润及血清AIF-1无关(P>0.05);Logistic多元回归分析显示,FIGO分期、宫旁浸润、肌层浸润及血清TFF3是影响宫颈癌淋巴结转移的独立因素(P<0.05);ROC曲线分析显示,TFF3对淋巴结转移有中等预测价值(AUC=0.649),明显大于机会参考线下面积(P<0.05)。而AIF-1、S100-A11、DKK1对淋巴结转移无预测价值(AUC分别为0.477、0.517、0.524),与机会参考线下面积比较无统计学意义(P>0.05)。结论 FIGO分期高、宫旁浸润、肌层浸润、血清TFF3异常升高是宫颈癌淋巴结转移的危险因素,血清TFF3有望成为预测宫颈癌淋巴结转移的新标志物;血清AIF-1、S100-A11、DKK1对宫颈癌淋巴结转移的预测效能不理想。

目的:研究甲状腺癌细针穿刺组织中BRMS1和Cx43的表达量及其与肿瘤恶性程度的相关性。方法:选择在我院接受甲状腺细针穿刺活检的患者进行研究,经病理学诊断后筛选甲状腺癌患者60例和甲状腺良性肿瘤患者60例,收集穿刺组织并测定BRMS1和Cx43的表达量,收集血清标本并测定Gal-3、CEACAM1、MMP2、MMP9的含量。结果:甲状腺癌组织中BRMS1和Cx43的mRNA含量及阳性表达率均显著低于甲状腺良性肿瘤组织;不同病理分型、肿瘤直径甲状腺癌组织中BRMS1、Cx43的mRNA含量无差异,TNM III-IV期甲状腺癌组织中Cx43的mRNA含量显著低于TNM I-II期甲状腺癌组织,不同TNM分期甲状腺癌组织中BRMS1的mRNA含量无差异,存在淋巴结转移的甲状腺癌组织中BRMS1、Cx43的mRNA含量显著低于无淋巴结转移的甲状腺癌组织;甲状腺癌组织中BRMS1、Cx43阳性表达患者的血清Gal-3、CEACAM1、MMP2、MMP9含量显著低于甲状腺癌组织中BRMS1、Cx43阴性表达患者。结论:甲状腺癌细针穿刺组织中BRMS1和Cx43的低表达与肿瘤的远处转移及恶性程度相关,Cx43的低表达还与肿瘤的生长以及癌细胞的增殖相关。

Kiss-1及nm23表达与乳腺癌淋巴结转移的关系

背景与目的:Kiss-1和nm23是肿瘤转移抑制基因,其蛋白表达与乳腺癌的转移密切相关。本研究探讨Kiss-1及nm23蛋白在乳腺癌中的表达与腋窝淋巴结转移的关系。方法:用免疫组化技术检测70例乳腺癌中Kiss-1及nm23蛋白表达。结果:乳腺癌中Kiss-1与nm23蛋白的阳性表达率分别为62.86%和68.57%,其中有淋巴结转移者的阳性表达率分别为38.46%和50.00%,明显低于无淋巴结转移者的阳性表达率77.27%和79.55%(P<0.05)。Kiss-1与nm23蛋白表达均阳性患者的淋巴结转移率(14.29%)明显低于其他患者(P<0.05)。结论:Kiss-1与nm23具有抑制乳腺癌淋巴结转移的作用,可能成为预测乳腺癌淋巴结有无转移的生物学标志。

STAT-3与Enolase-1在乳腺癌组织中的表达及意义

目的探讨乳腺癌组织中信号转导及转录活化因子3(STAT-3)和糖酵解酶烯醇化酶(Enolase-1)的表达与雌孕激素受体、淋巴结转移、临床分期、病理分级等的关系。方法免疫组织化学SP法检测126例乳腺癌和26例乳腺良性病变组织中STAT-3与Enolase-1的表达情况,并分析他们与临床病理参数之间的关系。结果乳腺癌组织中STAT-3和Enolase-1的阳性表达率分别为82.5%和77.8%,明显高于乳腺良性病变组织(11.5%和7.7%),差异均有统计学意义(χ2=42.416,P<0.05;χ2=57.211,P<0.05);在有淋巴结转移的乳腺癌组织中阳性表达率分别为85.7%和90.5%,高于无淋巴结转移组,差异均有统计学意义(χ2=9.184,P<0.05;χ2=11.014,P<0.05)。相关分析表明STAT-3和Enolase-1的表达呈正相关。在雌激素受体阳性(ER+)和/或孕激素受体阳性(PR+)或表皮生长因子受体2阳性(HER-2+)乳腺癌组织中,有淋巴结转移组中STAT-3和Enolase-1的表达水平均明显高于无淋巴结转移组,差异均有统计学意义(P<0.05)。结论 STAT-3与Enolase-1的表达与乳腺癌的发生发展及侵袭转移相关,且二者有协同作用(r=0.379,P<0.05)。在ER+和(或)PR+或HER-2+乳腺癌组织中,STAT-3和Enolase-1的高表达与淋巴结转移相关。在高表达STAT-3的乳腺癌组织中Enolase-1表达也较高,其联合检测可作为判断乳腺癌恶性程度、评价预后及指导治疗的一项评估指标。
