Serum levels of intercellular adhesion molecule ICAM-1 and E-selectin in advanced stage non-small cell lung cancer

Cell adhesion is a basic count in inter- and intra-cellular communication and plays an important role in tumor progression. This study was conducted to investigate the serum levels of intercellular adhesion molecule (ICAM-1) and E-selectin in patients with advanced stage non-small cell lung cancer (NSCLC) and the relationships with known prognostic parameters and therapy. These serum factors were measured of 57 NSCLC patients pathologically verified before and after chemotherapy in comparison with 24 healthy controls by using ELISA method. Serum levels of ICAM-1 were increased significantly in NSCLC patients compared with the healthy controls (P = 0.006). However, serum E-selectin levels were not significantly different from healthy control groups (0.643). No statistically significant relationships were found between investigated all serum parameters and various characteristics of patients, and the diseases such as stage and tumor burden. Likewise, we also found no correlation between serum ICAM-1 and E-selectin (P = 0.78). We found that serum ICAM-1 levels were decreased owing to the chemotherapy effect, independently from chemotherapy response. However, serum E-selectin levels were not changed by the chemotherapy effect. The median survival of all patients was 11.9 months and 1-year survival rate was 47.6%. We found that patients performance status (P = 0.013), age (P = 0.015), and weight loss (P = 0.007) were prognostic factors for survival. Serum E-selectin levels showed a trend (P = 0.08) related to worse prognosis, however serum ICAM-1 levels were determined as ineffective on survival (P = 0.11). Multivariate analysis revealed that only weight loss (P = 0.005) and E-selectin levels (P = 0.002) remained as an independent prognostic factor for survival in patients with advanced NSCLC. In conclusion, our data suggest that higher serum ICAM-1 can be useful for diagnosis while E-selectin levels have prognostic significance and could be a potential prognostic factor in NSCLC patients.     

Circulating intercellular adhesion molecule 1 (ICAM-1), E-selectin and vascular cell adhesion molecule 1 (VCAM-1) in head and neck cancer

The sera from patients with nasopharyngeal carcinoma (n = 30), oral carcinoma (n = 22) and laryngeal carcinoma (n = 22) was extracted before treatment. The concentration of circulating intercellular adhesion molecule 1 (ICAM-1), E-selectin and vascular cell adhesion molecule 1 (VCAM-1) was measured by enzyme-linked immunoassay and compared with those from normal subjects (n = 20). The concentration of circulating ICAM-1, E-selectin and VCAM-1 was significantly increased in nasopharyngeal carcinoma. Correspondingly, VCAM-1 and E-selectin were significantly increased in laryngeal carcinoma, whereas only E-selectin was elevated in oral carcinoma. The concentrations of these adhesion molecules did not significantly differ with respect to the early and late stages of these carcinomas. Elevated levels of soluble adhesion molecules in the sera of cancer patients at three different head and neck regions, although appearing to be implicated in these tumour formations, may be unrelated to tumour progression. © 1999 Cancer Research Campaign

Serum levels of IL-6 and TNF-alpha correlate with clinicopathological features and patient survival in patients with prostate cancer

Interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) are important multifunctional cytokines involved in tumour growth and metastasis. In this study, we have measured serial levels of serum IL-6 and TNF-alpha in prostate cancer patients. A total of 80 patients with carcinoma of the prostate and 38 controls were studied. Three patient groups, with small bulk localised, large volume localised and metastatic prostate cancer, were assessed. Serum IL-6 and TNF-alpha levels were measured and correlated with clinicopathological variables and patient survival. Serial changes in these cytokines were also assessed and related to disease progression in 40 patients with recurrent prostate cancer. Serum IL-6 levels in patients with metastatic disease (9.3+/-7.8 pg x ml(-1)) were higher than those in patients with localised disease (1.3+/-0.8 pg x ml(-1), P<0.001). Significantly elevated levels of TNF-alpha were found in metastatic disease (6.3+/-3.6 pg x ml(-1)) compared with localised disease (1.1+/-0.5 pg x ml(-1), P<0.001). The levels of both cytokines were directly correlated with the extent of the disease. Serial analysis in 40 patients with recurrent tumours showed that both cytokines became elevated at the point of prostate-specific antigen progression. In conclusion, these results suggest that IL-6 and TNF-alpha correlate with the extent of disease in patients with prostate cancer and may be monitored in conjunction with other disease markers.

Serum ICAM-1 in renal cell cancer patients: Possible significance for presence of metastatic disease

Background Intercellular adhesion molecule-1 (ICAM-1) facilitates cell-to-cell adhesion through lymphocyte function associated antigen-1 (LFA-1). ICAM-1 also exists as a soluble form (sICAM-1) and the level of sICAM-1 is known to increase in the presence of malignant tumors. Previously, we reported frequent ICAM-1 expression in renal cell cancer (RCC). sICAM-1 may suppress antitumor immune reactions by blocking LFA-1 on lymphocytes. Methods Serum sICAM-1 and IL-6, possible RCC autocrine growth factors, were examined in 35 RCC patients before and after surgery. In situ expression of sICAM-1 in RCC tissue and the degree of macrophage and lymphocyte infiltration were evaluated semiquantitatively using immunohistochemistry techniques. Results Nine pre- and 12 postoperative patients had elevated sICAM-1 levels. RCC patients with elevated sICAM-1 levels revealed a high ICAM-1 expression and/or high degree of lymphocyte/macrophage infiltration. Elevation or persistence of high sICAM-1 levels after nephrectomy correlated with the presence of metastatic disease (P=0.02); sICAM-1 was elevated in 5 of the 7 (71%) patients with metastasis compared with 7 of the 28 (25%) without evidence of metastatic disease. In some patients, however, the sICAM-1 level fluctuated without regard to the presence or absence of tumor after operation. Elevated sICAM-1 levels were also associated with high IL-6 levels. Conclusion Elevated sICAM-1 levels in RCC patients are not necessarily produced by RCC cells. However, in some cases, elevated sICAM-1 levels may be useful in detecting metastatic disease and aid in the development of treatment strategies and/or postnephrectomy follow-up therapies.     

结直肠癌患者血清可溶性E-选择素和细胞内黏附分子-1浓度的临床意义

目的:探讨结直肠癌患者可溶性E选择素(sEselectin)和细胞内黏附分子1(ICAM1)的血清浓度与结直肠癌转移的关系。方法:采用酶联免疫吸附实验方法(ELISA法)测定了64例结直肠癌患者可溶性E选择素和细胞内黏附分子1的血清浓度。同时测定癌胚抗原(CEA)的血清浓度。结果:可溶性E选择素的浓度和可溶性sICAM1的血清浓度显著增高,P=0001和P=0032,伴有远处转移者增高显著,P=0004和P=0015。可溶性E选择素的浓度和可溶性sICAM1的血清浓度与血清癌胚抗原的水平有相关性,P=0025和P=0038。结论:可溶性E选择素的浓度和sICAM1的血清浓度的升高可能与结直肠癌的发展和广泛转移有关。     

血清MMP-9和ICAM-1水平对非小细胞肺癌骨转移诊断和预后的意义

目的 探讨基质金属蛋白酶-9 (MMP-9）和细胞间粘附分子-1 (ICAM-l）在非小细胞肺癌（NSCLC）伴骨转移患者血清中的表达及其对预后的意义。方法 用ELISA 方法检测10 例健康对照者和70 例初治NSCLC 患者空腹血MMP-9 和ICAM-1 的表达,其中40 例NSCLC 患者伴骨转移Ⅳ期,30 例I ～Ⅱ期。结果 伴骨转移Ⅳ期NSCLC 患者血清MMP-9、ICAM-1 水平高于I～Ⅱ期NSCLC 患者,且两者均高于健康对照者。血清MMP-9、ICAM-1 水平与Ⅳ期伴骨转移患者的中位生存期显著相关,且血清MMP-9 水平可作为Ⅳ期伴骨转移NSCLC 的独立预后因素。结论 MMP-9和ICAM -1 均伴随NSCLC的发生发展以及疾病的进展而升高,对MMP-9 和ICAM-1表达的分析有助于评估Ⅳ期伴骨转移NSCLC 患者的预后,同时积极针对患者转移灶的治疗可以明显延长Ⅳ期伴骨转移NSCLC 患者生存期。

Thrombospondin-1 expression in oral squamous cell carcinomas: correlations with tumor vascularity, clinicopathological features and survival

Thrombospondin-1 (TSP-1) is a 450 kd glycoprotein synthesized and incorporated into the extracellular matrix by numerous cell types and reported to suppress tumor growth and progression by its inhibition of angiogenesis. In order to clarify the biological role of TSP-1 and determine its clinicopathological significance in oral squamous cell carcinomas (SCCs), we identified TSP-1 protein expression in 54 oral SCCs by immunohistochemistry and correlated it with microvessel density (MVD), clinicopathological features and patient's survival. Thirty-two out of 54 carcinomas (59%) were identified as having a low level of TSP-1 expression (TSP-1-L), and 22/54 (41%) carcinomas identified as having a high level of TSP-1 expression (TSP-1-H). The MVD counts (mean±S.D.=9.0±4.9) in TSP-1-H tumors was significantly lower than that (mean±S.D.=12.7±4.4) in TSP-1-H tumors (P=0.0065). The level of TSP-1 expression was not correlated with T category and histologic grade, but inversely correlated with the pattern of tumor invasion (P=0.0136) and with lymph nodal status (P=0.0119). Furthermore, Kaplan–Meier analysis showed that the 5-year survival rate of TSP-1-H group was significantly higher than that of TSP-l-L group. Our results suggested that TSP-1 expression exerts an inhibitory effect on tumor vascularity, and that it has value in assessment of aggressiveness and prognosis of oral SCCs.     

Levels of soluble intercellular adhesion molecule-1 and total sialic acid in serum of patients with colorectal cancer

BACKGROUND AND OBJECTIVES: Serum soluble intercellular adhesion molecule-1 (sICAM-1) and total sialic acid (TSA) are related to the metastatic potential of cancer cells. The purpose of the present investigation was to determine sICAM-1 and TSA levels in colorectal carcinoma and correlate their levels with the cancer stage. METHODS: The sera from 65 patients with colorectal cancer (18 at Dukes' B, 24 at Dukes' C, 23 at Dukes' D) were extracted before treatment. The concentrations of sICAM-1 and TSA were measured by enzyme-linked immunoassay and the thiobarbituric acid method, respectively, and compared with those from a healthy control group (n = 42). RESULTS: Mean serum sICAM-1 and TSA levels were found to be higher in the total patient group than in the control group (P < 0.0001). The concentrations of sICAM-1 and TSA were significantly higher in patients with Dukes' C and Dukes' D. The correlations between sICAM-1 and TSA became more significant as the stage of the disease increased (r = 0.58, P < 0.05 in Dukes' B, r = 0.88, P < 0.01 in Dukes' C and r = 0.81, P < 0.01 in Dukes' D). CONCLUSIONS: The results of this investigation indicate that sICAM-1 and TSA are the best of the tested markers. These markers should prove useful for monitoring malignant disease stage and for evaluating the effectiveness of various therapeutic approaches for colorectal carcinomas.

An overview of colorectal cancer survival rates and prognosis in Asia

Colorectal cancer is a rapidly rising trend in Asia.The incidence in many Asian countries is on par with the West.Several studies have provided data regarding the survival of patients with colorectal cancer.In Asia,the overall cure rate of colorectal cancer has not improved dramatically in the last decade,5-year survival remaining at approximately 60%.Colorectal cancer survival time has increased in recent years,but mortality rate remains high.Although studies have determined a number of factors that can predict survival of patients after diagnosis,life expectancy has not been increased dramatically.It seems that among the prognostic factors explored so far,the most important are those that relate to early diagnosis of cancer.Primary detection is feasible since efficient screening modalities are available.Colonoscopic surveillance is needed,especially in subjects at higher risk.     

胃癌组织中Ets-1的表达及其与血管生成临床病理特征和预后的关系

Objective To investigate the expression of Ets-I in gastric carcinoma,pars-cancerous tissue and metastatic lymph nodes,and to determine the relationship between Ets-1 expression and clinicopathological features,angiogenesis and survival of patients with gastric carcinoma.Methods Gastric carcinoma tissue microarray was used to determine Ets-I protein expression by SP immunohistochemical staining in 189 advanced gastric cancer,54 papacancerous tissues,41 metastatic lymph nodes and 32 control tissues.Results The positive rates for Ets-1 expression of the carcinoma,paracancerous and control tissues were 71.4 %,29.6% and 18.8%,respectively,with a significant difference among the three groups(P ＜0.01).In the cancer tissues,the positive rate of Ets-1 protein expression was significantly associated with depth of invasion and lymph node metastasis(P ＜0.01),but not associated with degree of differentiation,Lauren's histological type,sex,age,and size of tumor(P ＞0.05).The positive rates for Ets-1 expression of the 41 gastric cancer and 41 metastatic lymph nodes were significantly different(P ＜0.05).In metastatic lymph nodes,the positive rate for Ets-1 expression was higher.The MVD in Ets-1 positive tumors was higher than that in the Ets-1 negative tumors,with a significant difference(P ＜ 0.05).Kaplan-Meier survival analysis showed that the survival time of Ets-1-negative patients was longer than that of Ets-1-positive patients (P ＜0.05).Cox regression analysis showed that Ets-1 expression was not an independent prognostic factor of gastric carcinoma.Conclusion A higher expression of Ets-1 is involved in carcinogenesis,development,invasion,and metastasis of gastric cancer.Ets-1 plays an important role in angiogenesis in gastric cancer.Ets-1 is a useful marker for predicting the outcome for patients with gastric carcinoma,though it is not an independent prognostic indicator.
