The systemic inflammatory response, as evidenced by elevated circulating concentrations of C-reactive protein, is a stage-independent prognostic factor in patients undergoing curative nephrectomy for localised renal cancer. However, it is not clear whether the systemic inflammatory response arises from the tumour per se or as a result of an impaired immune cytokine response. The aim of the present study was to examine C-reactive protein, interleukin-6 and interleukin-10 concentrations before and following curative resection of renal cancer. Sixty-four patients with malignant renal disease and 12 with benign disease, undergoing resection were studied. Preoperatively, a blood sample was collected for routine laboratory analysis with a further sample stored before analysis of interleukin-6 and interleukin-10 using an enzyme-linked immunosorbent assay (ELISA) technique. The blood sampling procedure and analyses were repeated at approximately 3 months following resection. Circulating concentrations of both interleukin-6 and interleukin (P< or =0.01) were higher and a greater proportion were elevated (P<0.05) in malignant compared with benign disease. The renal cancer patients were grouped according to whether they had evidence of a systemic inflammatory response. In the inflammatory group T stage was higher (P<0.01), both interleukin-6 and interleukin-10 concentrations were higher (P<0.001) and elevated (P<0.10) compared with the non-inflammatory group. Tumour volume was weakly correlated with C-reactive protein (r(2)=0.20, P=0.002), interleukin-6 (r(2)=0.20, P=0.002) and interleukin-10 (r(2)=0.24, P=0.001). Following nephrectomy the proportion of patients with elevated C-reactive protein, interleukin-6 and interleukin-10 concentrations did not alter significantly. An elevated preoperative C-reactive protein was associated with increased tumour stage, interleukin-6 and interleukin-10 concentrations. However, resection of the primary tumour did not appear to be associated with significant normalisation of circulating concentrations of C-reactive protein, interleukin-6 or interleukin-10. Therefore, the presence of systemic inflammatory response is unlikely to be solely be determined by the tumour itself, but may be as a result of an impaired immune cytokine response in patients with renal cancer. 相似文献

Pro-inflammatory cytokines, such as interleukin-lβ (IL-lβ), interleukin-6 (IL-6) and tumor necrosis factor- (TNF-α) play an
essential role in the regulation of immune response to, and may have prognostic significance in, cancer. The aim of this study
was to examine the relationship between the serum levels of IL-lβ, IL-6 and TNF-α as well as the concentrations of soluble
TNF receptor I (sTNF-RI) and C-reactive protein (CRP) in patients with squamous cell carcinoma of oral cavity. Results obtained
were confronted with squamous cell carcinoma antigen (SCO concentrations. IL-lβ IL-6 and TNF-α serum levels as well as sTNF-RI
and CRP concentrations were higher in patients than in controls. The increased serum levels appeared to be related to the
clinical stage of disease. There was a correlation between IL-lβ and sTNF-RI. IL-6 and IL-lβ correlated with CRP levels. The
mean concentrations of SCC were also elevated. IL-6 and sTNF-RI seemed to be the most sensitive parameters in early stages
and may be used as additional markers in oral cancer 相似文献

Serum levels of interleukin-6 (IL-6), interleukin-8 (IL-8) and tumor necrosis factor (TNF)-alpha were frequently measured during the first 30 days after allogeneic bone marrow transplantation (BMT) in 84 consecutive adult patients. Major transplant-related complications (MTCs) occurred in 33% of cases and included veno-occlusive liver disease, idiopathic pneumonia syndrome, severe endothelial leakage syndrome and >grade II acute graft-versus-host disease. Compared with patients having minor complications, those with MTCs developed higher levels at times of maximal clinical signs (all cytokines, P<0.001), between days 0-5 post-BMT (IL-6 and IL-8, P<0.05) and days 6-10 (L-6, P<0.001; IL-8 and TNF, P<0.01) post-BMT. We could not discriminate patterns of cytokine release that were specific for any subtype of MTC. Higher levels of IL-8 during days 0-5 were associated (P=0.044) with early (<40 days) death. Multivariate analysis including patient and transplant characteristics as well as post-BMT levels of C-reactive protein showed that high average levels of one or more of the cytokines within the first 10 days post-BMT were independently associated with MTC (Odd's ratio: 2.3 [1.2-4.5], P=0.011). This study shows that systemic release of proinflammatory cytokines contributes to the development of MTC and provides a rationale for pre-emptive anti-inflammatory treatment in selected patients. 相似文献

Induction of gp130 and LIF by differentiation inducers in human myeloid leukemia K562 cells 总被引:1,自引:0,他引:1
It has been previously shown that phorbol 12-myristate 13-acetate (PMA), a potent differentiation inducer, induced the expression of both interleukin-6 (IL-6) and IL-6 receptor alpha component (IL-6Ralpha) in K562 leukemia cells. In the present study, we examined the ability of several differentiation inducers to regulate the expression of the signal-transducing receptor component for IL-6, gp130, and cytokine leukemia inhibitory factor (LIF) in K562 cells. We found that the expression of gp130 was dramatically induced at both the mRNA and protein levels by the two megakaryocytic inducers sodium butyrate (NaBut) and PMA. In contrast, the mRNA expression of LIF was induced by the two erythroid inducers 1-beta-D-arabinofuranosyl cytosine (Ara-C) and hemin. Furthermore, activation of the PMA-induced gp130 receptor by exogenous IL-6 potentiated the differentiating effects of PMA. Our findings suggest that IL-6/gp130 signaling may be involved in the regulation of the megakaryocytic differentiation of K562 cells. 相似文献

BACKGROUND AND OBJECTIVES: We analyzed the correlations between pretreatment serum levels of 11 cytokines and soluble cytokine receptors (interleukin 6 (IL-6); interleukin 8 (IL-8); interleukin 10 (IL-10); vascular endothelial growth factor (VEGF); basic fibroblast growth factor (bFGF); macrophage colony-stimulating factor (M-CSF); granulocyte colony-stimulating factor (G-CSF); interleukin 1 receptor antagonist (IL-1ra); sIL-2Ralpha; tumor necrosis factor receptor I (TNF RI), and TNF RII) with clinico-pathological features and survival of patients with bone sarcomas. METHODS: Altogether, 72 patients with bone sarcomas without distant metastases before treatment (26 osteosarcomas-36%, 23 chondrosarcomas-32%, 13 Ewing's sarcomas/PNET-18%, 10 giant-cell tumors-14%), 22 patients with benign non-inflammatory bone tumors and 50 age-matched healthy controls were included into this prospective study. RESULTS: Median serum levels of 9/11 cytokines, with the exception of sIL-2Ralpha and G-CSF, were significantly higher in sarcoma patients than in controls. Median serum levels of IL-6, IL-8, IL-1ra, TNF RI, and M-CSF were significantly higher in patients with bone sarcoma as compared to patients with benign bone tumors. In 45.9% of sarcoma patients, six or more cytokines and cytokine receptors, including those that are involved in bone destruction (e.g., IL-6 and IL-8) and bone formation (e.g., IL-1ra and TNFRI and TNFRII), were elevated in parallel. Serum levels of IL-6, IL-8, TNF RI, TNF RII, and VEGF correlated significantly with tumor size (<10 cm vs. >or=10 cm in diameter) and serum levels of IL-6, IL-8, TNF RI, and IL-1ra correlated significantly with local tumor extent (E2/4 vs. E5/6 according to the classification proposed by Spanier et al. 46). Moreover, serum levels of IL-1ra and IL-6 were significantly higher in patients with small tumors (<5 cm in diameter) infiltrating structures adjacent to the periosteum (E5/6) than in large tumors (>10 cm in diameter) but confined to the bone and periosteum (E < 4). The lowest median serum levels of 8/11 cytokines/cytokine receptors were found in patients with giant-cell tumors. In an univariate analysis, increased serum levels of IL-1ra, IL-6, IL-8, IL-10, sIL-2Ralpha, M-CSF, TNF RI, and TNF RII, the number of cytokines elevated, higher tumor grade, larger tumor size, greater local extent (E) and patients' age >35 years correlated with poor overall survival (OS) (P < 0.05). Similarly, high serum levels of IL-1ra, IL-6, TNF RI and TNF RII, tumor grade, tumor size, and tumor local extent (E) (P < 0.05) affected disease free survival (DFS) in univariate analysis. Multivariate analysis using Cox's proportional hazards model showed that high serum levels of IL-1ra (P = 0.039) and TNF RI (P = 0.048), the number of serum cytokines above normal cut-off values (0-1 vs. 2-5 vs. >or=6; P = 0.029), greater tumor local extent E (E2/4 vs. E5/6; P = 0.02) correlated significantly with shorter OS. Only E was found as an independent prognostic factor for DFS (P = 0.04). CONCLUSIONS: These findings indicate that cytokines and soluble cytokine receptors, both physiologically involved in bone destruction and bone formation, have an essential role in the progression of malignant bone tumors. 相似文献

In our RT-PCR screen for cytokine expression in human brain tumors we discovered increased levels of oncostatin M (OSM), ciliary neurotrophic factor (CNTF) and leukemia inhibitory factor (LIF), all belonging to the interleukin-6 (IL-6) cytokine family, in most of the tumors. The expression of these cytokines in normal adult brain tissue was found to be very low or below detection limit. OSM expression was elevated in most of the tumors and immunohistochemistry analysis showed that the tumor cells contained OSM in their cytoplasm, suggesting they produce this factor. Overexpression of OSM has not previously been reported in primary human brain tumors. The IL-6 cytokine family acts through a common gp130 receptor subunit that activates the JAK/STAT signaling pathway and therefore they have been suggested to have overlapping effects. Tissue inhibitor of metalloproteinase-1 (TIMP-1), matrix metalloproteinase 1 (MMP-1) and MMP-3 and IL-6 have been reported to be regulated by OSM. IL-6 was low or absent in the tumors. TIMP-1, MMP-1 and MMP-3 was expressed in most tumors but with no strict correlation to OSM levels. 相似文献

OBJECTIVES: Cytokines are potential new serum markers, especially desirable for malignancies with poor prognosis like non-small cell lung cancer (NSCLC). METHODS: Cytokines, tumor necrosis factor alpha (TNFalpha), interleukin (IL)-6 and IL-8, soluble TNF (sTNF) RI, sTNF RII, soluble IL-2 receptor-alpha, IL-1 receptor antagonist (IL-1ra), IL-10, vascular endothelial growth factor, basic fibroblast growth factor, and macrophage (M-CSF) and granulocyte colony-stimulating factor, as well as tumor markers - carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC) and CYFRA 21.1 - were assessed in the sera of 103 untreated NSCLC patients, and these cytokines and tumor markers were referred to clinical parameters of the disease and to the overall survival of patients evaluated during a 6-year follow-up. RESULTS: Most of the factors analyzed were found to be elevated in the sera of NSCLC patients, and increases in IL-6, IL-8 and sTNF RI were noted in the greatest proportion of stage I patients. Most cytokine/cytokine receptor levels revealed higher sensitivity than the standard tumor markers; IL-6 and IL-1ra levels were significantly different in patients with squamous cell versus adenocarcinoma; IL-6 and IL-10 were related to the tumor size, while IL-6 and M-CSF levels significantly increased with disease progression. A significant prognostic value of pretreatment serum M-CSF and CEA levels in NSCLC patients has been shown, but only M-CSF proved to be an independent prognostic factor. CONCLUSIONS: Increased pretreatment serum M-CSF level is a significant independent predictor of poor survival in patients with NSCLC. 相似文献

The relationship between interleukin-6 and C-reactive protein was evaluated in patients with benign (n=59) and malignant (n=86) prostate disease. The correlation coefficients for patients with benign prostatic disease and prostate cancer were rs=0.632, P<0.001 and rs=0.663, P<0.001, respectively. These results indicate that the relationship between interleukin-6 and C-reactive protein is similar in patients with benign and malignant prostate disease. 相似文献

Interleukin-6 (IL-6) is produced at high levels by renal cell carcinoma cell lines. The molecular mechanisms involved in its possible role as an autocrine growth factor were investigated. IL-6 and IL-6 receptor expression was investigated in 8 renal cell carcinoma (RCC) cell lines. The modulation of RCC cell line proliferation by an anti-IL-6 Ab, an IL-6 antisense oligonucleotide (ASON) directed against the second exon of IL-6 and cytokines inhibiting IL-6 production (IL-4 and IL-13) was investigated. All 8 RCC cell lines expressed IL-6 mRNA, produced IL-6 and expressed the soluble and membrane-bound gp130 chain of IL-6 receptor. The gp80 chain of IL-6 receptor was undetectable at the surface of the 8 RCC cell lines tested, while the soluble form of gp80 was detectable in the supernatant of one of these cell lines. The addition of a blocking IL-6 Ab did not inhibit the proliferation of any of the 8 RCC cell lines. In contrast, IL-6 ASON inhibited specifically IL-6 production and the proliferation of all RCC cell lines. Exogenous IL-6 failed to restore RCC cell line proliferation blocked by ASON, indicating that IL-6 acts through an intracrine loop in RCC cell lines. IL-13 and IL-4 inhibited the proliferation of 7 of the 8 cell lines without interfering with IL-6 or IL-6 receptor expression. IL-6 ASON inhibited the proliferation of the 8 RCC cell lines tested additively with IL-4 or IL-13. IL-6 is an intracrine growth factor in renal cell carcinoma cell lines. 相似文献

The aim of this study was to exploit the potential clinical use of circulating cytokine measurements in colorectal cancer (CRC) patients. The levels of cytokines and cytokine receptors were assessed by ELISA in the sera of 50 healthy volunteers and 157 patients with previously untreated CRC and then related to clinicopathological features and prognosis. All tumors were verified histologically as colorectal adenocarcinomas and staged according to TNM classification. The levels of circulating interleukin (IL)-6, IL-8, macrophage colony-stimulating factor (M-CSF) and interleukin 1 receptor antagonist (IL-1ra) significantly increased with the clinical stage of CRC, and the levels of IL-6, soluble tumor necrosis factor (sTNF) receptor type I (RI), soluble interleukin 2 receptor alpha and TNFalpha with tumor grade, while IL-6, IL-8, M-CSF, IL-1ra and sTNF RI levels significantly rose with bowel wall invasion. None of the cytokine or soluble cytokine receptor levels were influenced by age, gender and colon versus rectum localization. sTNF RI, IL-8, IL-6 and vascular endothelial growth factor measurements demonstrated the highest diagnostic sensitivity. sTNF RI was found elevated in the greatest percentage of all CRC patients, in the greatest proportion of stage I patients and presented the best diagnostic sensitivity. In addition, the sTNF RI level strongly correlated with tumor grade and invasion and proved to be an independent prognostic factor. 相似文献

The relationship between the systemic inflammatory response (as evidenced by elevated C-reactive protein and lowered albumin concentrations), clinico-pathologic status and relapse-free, cancer-specific and overall survival was examined in patients with invasive primary operable breast cancer (n=300). The median follow-up of the survivors was 46 months. During this period, 37 patients relapsed and 25 died of their cancer. On multivariate analysis, only tumour size (P<0.05), albumin (P<0.01) and systemic treatment (P<0.0001) were significant independent predictors of relapse-free, cancer-specific and overall survival.

ObjectivesTo investigate changes in inflammatory biomarkers during induction therapy for older adults with acute myeloid leukemia (AML) and their associations with geriatric assessment (GA) measures and outcomes.MethodsThis was a single institution ancillary study to a prospective observational study (N = 20 consecutive adults aged ≥60 with newly diagnosed AML who received induction chemotherapy). Biomarkers (Interleukin-6 [IL-6], IL-6 soluble receptor [IL-6 sR], tumor necrosis factor alpha [TNFα], TNFα soluble receptor 1 [TNFα sR1], interleukin-3 [IL-3], C-reactive protein [CRP]) were collected at start of induction, weekly for three weeks, and post-induction and were compared over time using paired t-tests. GA was administered at baseline and post-induction, and correlated with biomarker levels using Spearman correlations. Survival was estimated using Kaplan-Meier and compared by categorized biomarker level using Wilcoxon tests.ResultsBiomarker levels were stable during induction, except for CRP and IL-6 sR. Declines in objectively measured physical function [Short Physical Performance Battery (SPPB); r = 0.71, p < 0.01] and increases in self-reported limitation in instrumental activities of daily living (r = 0.81, p < 0.01) were correlated with increased TNFα sR1. Declines in SPPB were correlated with increased CRP (r = −0.73, p < 0.01). Improvement in depression was correlated with increased IL-6 sR (r = −0.59 p = 0.02). Survival was shorter in those with baseline TNFα or CRP levels above the median (6.1 vs. 40.2 months and 5.5 vs. 27.6 months respectively, p = 0.04 for both).ConclusionAmong older adults with AML, the relationships between TNFα sR1, CRP, and IL-6 sR with change in physical and emotional health during treatment warrants further investigation. 相似文献

Assay of cytokines and C reactive protein (CRP) in different periods of febrile neutropenia may be helpful for early defining
the risk in severe infections. We determined serum interleukin-6 (IL-6), interleukin-8 (IL-8), soluble interleukin-2 receptor
(sIL-2R), tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), and CRP in 22 previously untreated patients with
various malignancies. Samples were obtained in four different clinical periods of febrile neutropenia; prior to chemotherapy,
afebrile neutropenic period after chemotherapy, febrile neutropenic period, and recovery period. When compared to sex-and
age-matched group of healthy subjects, IL-6, IL-8, sIL-2R, and CRP levels were found to be elevated in all periods. The highest
levels were encountered in the febrile neutropenic period. For predictivity purposes, the afebrile neutropenic period was
the most important period. Serum sIL-2R, IL-6, IL-8 and CRP levels were elevated in this period. IL-8 levels showed the most
stable elevation through different stages of febrile neutropenia. Serum IL-8 levels were found to have the most reliable and
stable elevation in different clinical stages of febrile neutropenia. Nevertheless, IL-8 is not able to discriminate among
risk groups and cannot be used as a predictive factor. 相似文献

Retinoic acid inhibits IL-6-dependent but not constitutive STAT3 activation in Epstein-Barr virus-immortalized B lymphocytes 总被引:2,自引:0,他引:2

IL-6-mediated B-cell growth promotion is involved in the pathogenesis of EBV+ lymphoproliferative disorders of immunosuppressed patients. Since retinoic acid (RA) inhibits the proliferation of EBV-immortalized lymphoblastoid B-cell lines (LCLs), we have investigated the effects of RA on IL-6 signaling in these cells. RA down-regulated IL-6-receptor components with IL-6 agonist activity (membrane and soluble gp80) and increased the levels of soluble gp130, an IL-6 antagonist. These changes, however, were not related to the enhanced production of endogenous IL-6 induced by RA in LCLs. RA-induced modulation of IL-6 receptor components did not abolish IL-6-mediated phosphorylation of gp130, whereas JAK1 and STAT3 phosphorylation and activation induced by IL-6 were markedly inhibited. Overall, the effects of RA resulted in the induction of a complete resistance of LCLs to IL-6-mediated growth promotion. Conversely, RA did not inhibit the constitutive activation of JAK1, TYK2, STAT3 and ERK1/2, ruling out that the JAK/STAT and MAPK pathways may mediate the antiproliferative activity of RA. The finding that RA severely impairs IL-6-dependent signalings in LCLs and inhibits their growth despite the presence of constitutively active JAK/STAT and MAPK cascades provide additional support for a role of RA in the prevention and treatment of EBV-related lymphoproliferative disorders of immunosuppressed patients. 相似文献

Enhanced concentrations of soluble forms of the receptor for tumour necrosis factor (TNF)-α have been detected in the serum of cancer patients. We determined serum concentrations of soluble TNF receptor p55 (sTNF-R55) in patients with haematological neoplasias, 50 patients suffering from non-Hodgkin's lymphoma (n = 35), Hodgkin's disease (n = 10) and multiple myeloma (n = 5). Compared with healthy controls and with patients with potential thyroid disease, significantly elevated concentrations of sTNF-R55 were found (mean ± standard error: 2.68 ± 0.22 vs. 1.23 ± 0.21 ng/ml, P < 0.0001 and 2.18 ± 0.32 ng/ml, P = 0.03). Likewise, neopterin concentrations were raised (19.6 ± 3.66 vs. 5.3 ± 0.25 nmol/l in controls, P < 0.0001). We found a significant correlation between sTNF-R55 and neopterin concentrations (Rs = 0.544, P < 0.001). Patients with weight loss showed higher sTNF-R55 concentrations than patients with stable weight. Our results confirm the relevance of sTNF-R55 concentrations in serum of patients with cancer. 相似文献

Patients with pancreatic cancer frequently demonstrate symptoms such as weight-loss and muscle wasting and have clinical evidence of a systemic inflammatory response. Such effects may be mediated by pro-inflammatory cytokines derived from tumor cells. The production of interleukin-6 and -8 by pancreatic cancer cell lines and the influence of other cytokines on this production was studied. IL-8 was produced by all cell lines and production was increased following exposure to IL-1 and TNF. Cytokine-stimulated, but not basal IL-8 production was reduced by co-incubation with IL-4 in the MIA PaCa-2 and PANC-1 cell lines. The CFPAC cell line produced IL-6, but this production was not altered by IL-1, TNF or IL-4. In the PANC-1 cell line IL-8 and IL-8 receptors were only detected by PCR in cells which had been stimulated with TNF or IL-1. Serum concentrations of IL-6 and IL-8 were elevated in patients with pancreatic cancer compared with controls. In conclusion, human pancreatic cancer cell lines elaborate pro-inflammatory cytokines which have the potential to mediate elements of the systemic inflammatory response. 相似文献

AIMS: Acute phase reactants (APRs) are believed to play an important biological role in trauma, sepsis and malignant disease. We have investigated the induction of the APR, C-reactive protein (CRP), by the biological response modifier, polyadenylic-polyuridylic acid (PAPU) during the peri-operative period. METHODS: Twenty post-menopausal women with breast cancer undergoing mastectomy were randomized into a double blind, placebo-controlled, parallel group pilot study. PAPU (150 mg) or placebo was given intravenously the day prior to surgery (D -1), the day of surgery (D 0) and post-operatively on days (D 1, 3, 5, 7 and 14). Blood samples were collected on eight different days (D -2, -1, 0, 1, 2, 4, 6 and 18). CRP was significantly elevated in the PAPU group (P<0.05) on days 2 and 4, when compared with patients receiving placebo. The serum levels of cytokines believed to induce hepatic APRs, were also measured. RESULTS: The serum concentration of IL-6 was elevated on days 1, 2, 4 and 6 (P<0.05), TNF- alpha and IL-1 beta levels were increased on days 1 and 2 (P<0.05), respectively, while the serum level of soluble interleukin-2 receptor (sIL-2R) was elevated above the baseline on days 0, 2, 4, 6 and 18 in the PAPU group, when compared with the baseline. CONCLUSIONS: This modulation of acute phase response may have important implications for patients with cancer undergoing surgery. 相似文献
