Recently E-selectin (ELAM-1, endothelial leukocyte adhesion molecule-1) was shown to recognize not only sialyl Lewis X but also sialyl Lewis A, and these carbohydrate antigens may be involved in the process of the adhesion between cancer cells and endothelial cells in cancer metastasis. To investigate the contribution of sialylated carbohydrate antigen, SPan-1, and sialic acid to the adhesion of human colon cancer cells to endothelial cells, adhesion assay using HUVECs (human umbilical vein endothelial cells) was performed. The adhesion was significantly inhibited by pretreatment with anti-E-selectin antibody, indicating that this adhesion was thought to be mediated by E-selectin. When these cancer cells were pretreated with SPan-1 antibody, the adhesion was significantly inhibited in a concentration-dependent manner. The adhesion was also inhibited by pretreatment with neuraminidase. These findings suggest that the SPan-1 antigen plays a significant role in the adhesion of human colon cancer cells to endothelial cells, and sialylation of the terminal structure of carbohydrate antigens is important in this adhesion.Part of this study was presented at the Second Osaka International Symposium on Gastroenterology held in Osaka, Japan on November 22–23, 1993. 相似文献

Background Purpose
Although carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are the most studied serum tumor markers that have been evaluated for diagnosis and prognosis in patients with pancreatic cancer, little is known of the value of these markers for the prediction of curability and resectability.Methods
We retrospectively reviewed preoperative serum levels of CEA and CA 19-9 in 244 consecutive patients with pancreatic operations.Results
Although 159 pancreatic operations seemed “resectable”, 93 of them were judged curative (R0) and the other 66 turned out to be noncurative (R1/2). The remaining 85 failed resection because of unexpected metastasis or locally advanced disease (LD), which was unresectable compared with levels in those patients without liver metastasis or LD. CEA levels were significantly higher in patients with liver metastasis and LD, while CA 19-9 levels were correlated with liver and peritoneal metastases. When both markers were negative, curative (R0) and respectable (R0 + R1/2) operation were performed in 70% and 85% of patients, respectively. Logistic regression analysis indicated that under conditions where both CEA and CA 19-9 were negative, the odds ratios for curative and respectable operations were 4.43 and 3.58, respectively.Conclusions
Our data suggest that combined preoperative CEA and CA 19-9 levels are suitable for assessing expected curability and resectability in patients with pancreatic cancer.13.

OBJECTIVE: The aim of the present study was to examine the impact of sputum carcinoembryonic antigen (CEA), neuron-specific enolase (NSE) and cytokeratin fragment 19 (CYFRA 21-1) levels in lung cancer diagnosis and to compare the diagnostic usefulness of sputum assays with that of serum assays. METHODOLOGY: Forty-seven patients with lung cancer and 62 with benign lung disease were studied. Tumour marker levels in sputum (sp.) and serum (ser) were measured by immunoradiometric assays. RESULTS: Sputum and serum tumour marker levels were significantly higher in lung cancer than in benign disease. When the specificity was 95%, the sensitivity was 57%, 43%, 36%, 30%, 28% and 19%, for spCEA, serCYFRA 21-1, spCYFRA 21-1, serCEA, serNSE, and spNSE, respectively. Bayesian analysis showed that the best predictive values correspond to spCEA and serCYFRA 21-1. The maximum overall gain was obtained in pretest probability of 0.35 for both spCEA and serCYFRA 21-1, with predictive values of 84% and 80% for spCEA and serCYFRA 21-1, respectively. CONCLUSION: Sputum tumour marker levels were no more useful than the serum levels in lung cancer diagnosis. SpCEA offered the best predictive values but these were still not sufficiently satisfactory for spCEA to be proposed for routine use. 相似文献

Distant metastasis explains the high mortality rate of colon cancer, in which lung metastasis without liver metastasis (LuM) is a rare subtype. This study is aimed to identify risk factors of LuM and LLM (lung metastasis with liver metastasis) from colon cancer, and to analyze the prognosis of patients with LuM by creating a nomogram. Patients’ information were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Multivariable logistic regression analysis was used to determine the risk factors for LuM and LLM. Prognostic factors for cancer-specific survival (CSS) and overall survival (OS) were identified by multivariate Cox proportional hazards regression and nomogram models were established to predict CSS and OS. Multivariate logistic regression analysis showed that blacks, splenic flexure of colon tumor, tumor size >5 cm, T4, N3, and higher lymph node positive rate were associated with the occurrence of LuM. Meanwhile, age >65 years old, female, splenic flexure of colon, higher lymph node positive rate, and brain metastasis were independent risk factors for CSS. The C-index of the prediction model for CSS was 0.719 (95% CI: 0.691–0.747). In addition, age, primary site, tumor size, differentiation grade, N stage, and bone metastasis were significantly different between LuM and LLM. The nomograms we created were effective in predicting the survival of individuals. Furthermore, patients with LuM and LLM from colon cancer might require different follow-up intervals and examinations. 相似文献

目的探讨糖类抗原15-3(CA15-3)在评价乳腺癌骨转移的价值。方法纳入在我院接受手术经病理学确诊的86例乳腺癌患者。采用99mTc-MDP核素骨显像检查并进一步病理学确认患者是否发生骨转移,记录发生骨转移的部位和数目。根据是否发生骨转移将患者分为2组。采用化学发光法检测所有患者血清CA15-3水平,比较2组患者CA15-3水平,分析CA15-3水平与骨转移累及部位数目的相关性;采用ROC曲线分析CA15-3水平对乳腺癌骨转移的诊断价值。结果乳腺癌骨转移组血清CA15-3水平高于无骨转移组(P<0.01)。骨转移累及部位数目与CA15-3水平的Spearman相关性分析结果显示两者并无相关性(r=-0.056,P=0.768)。ROC曲线分析结果显示CA15-3血清水平用于判断乳腺癌骨转移有显著意义(P=0.000)。当选CA15-3 24.675 U/mL为诊断界点,灵敏度为91.7%,特异度为93.8%。结论 CA15-3水平可以作为乳腺癌骨转移诊断的初步筛选指标。 相似文献
