Abstract
Basic fibroblast growth factor (bFGF) stimulates angiogenesis, influencing the proliferation, migration, and survival of tumour cells, which have pivotal roles in tumour progression. This study investigated the prognostic significance of bFGF expression in lung adenocarcinoma treated with bevacizumab. The expression levels of bFGF were assessed in bevacizumab-treated patients with lung adenocarcinoma using immunohistochemistry. Propensity score matching (PSM) analysis was performed to evaluate prognostic potential. bFGF expression was also investigated in another independent cohort of patients with lung adenocarcinoma treated with routinechemotherapy. We also compared the PSM value of bFGF expression levels independently and in combination with epidermal growth factor receptor and vascularendothelial growth factor expression levels. A high bFGF expression level was found to be an independent prognostic factor for disease-free survival in patients receiving bevacizumab-based chemotherapy. Similar results were not observed in patients who underwent routinechemotherapy. In conclusion, the bFGF expression level may be a clinically feasible prognostic marker and bFGF is a potential therapeutic target for patients with lung adenocarcinoma receiving routinechemotherapy.

Abstract
Introduction: Lung cancer was considered to be rare at the beginning of the 20th century, but it has now reached almost epidemic proportions. It is the leading cause of cancer deaths in developed countries and is also rising at alarming rates in developing countries. Introduction: Coronavirus disease 2019 (COVID-19) is an emerging viral infection without any approved treatment. Investigational therapies for COVID-19 may cause clinically important drug-drug interactions (DDIs). We aimed to study drug-drug interactions (DDIs) and their risk factors in hospitalised COVID-19 patients. Aim: The aim of our study is to establish an effect on serum levels of vascular endothelial growth factor (VEGF) after surgery in lung cancer patients. Methods:This was a prospective study. For the estimation of VEGF, 50 lung cancer patients were studied. Both preoperative and postoperative levels of VEGF were estimated for all subjects. Blood samples were obtained from all cases both preoperatively and postoperatively (four weeks after surgery). Blood samples of 100 age and sex matched healthy controls were collected from the Outpatient Departments of SKIMS to establish normal serum VEGF levels. Conclusion: Our findings show that serum VEGF levels are higher as the tumor stage progresses and tumor size increases, which explains the lower serum VEGF levels observed by us in the operable patient group.

Abstract
BACKGROUND Acute pancreatitis (AP) is a symptom of sudden pancreas inflammation, which causes patients severe suffering. In general, fibroblast growth factor (FGF) levels are increased and amylase and lipase activities are elevated during AP pathogenesis, but protein concentration are low. However, the mechanism through which FGF signaling regulates AP pathogenesis remains elusive. MATERIAL AND METHODS The concentrations of PGE2, TNF-alpha, sCRP, FGF1, and FGF2 in the serum samples of the AP group and healthy control group were detected by enzyme-linked immunosorbent assay. In addition, IkappaBalpha and p-IkappaBalpha levels were analyzed in the serum samples. Subsequently, the AP rat model was established, and FGF1, FGF2, anti-FGF1, and anti-FGF2 antibodies and Bay11-7082 were injected into AP rats. TNF-alpha, PAI-1 JNK, p-JNK, IkappaBalpha, and p-IkappaBalpha levels were also examined. RESULTS Results showed that levels of PGE2, TNF-alpha, sCRP, p-IkappaBalpha, FGF1, and FGF2, as well as amylase and lipase activity were increased in patients with AP compared with those in healthy people. In addition, protein concentrations were lower in patients with AP than in the healthy group. Activation of FGF signaling by injecting FGF1 or FGF2 also inhibited AP-induced inflammation response in the pancreas and increased amylase and lipase activities, as well as protein concentration. However, the injection of FGF1 and FGF2 antibodies accelerated AP-mediated inflammation responses in the serum. In addition, Bay11-7082 injection inhibited AP activation of inflammation response and amylase and lipase activities. Protein concentration were also increased in AP rats. CONCLUSIONS FGF signaling protects against AP-mediated damage by inhibition of AP-activating inflammatory responses.

Abstract
Aim This study was designed to investigate the predictive and prognostic values of serum vascular endothelial growth factor (VEGF) level in non-small cell lung cancer (NSCLC) patients treated with platinum-based chemotherapy. Methods Patients’ peripheral blood samples were collected prior to chemotherapy and after 1 week of the third cycle of combination chemotherapy. Serum VEGF levels were evaluated through Luminex multiplex technique. Between September 2011 and August 2015, a total of 135 consecutive advanced or recurrent histologically verified NSCLC patients were enrolled in the study. Moreover, all the patients received platinum-based combination chemotherapy as a first-line treatment. Results No significant associations were found between pretreatment serum VEGF levels and clinical characteristics, such as sex (P=0.0975), age (P=0.2522), stage (P=0.1407), lymph node metastasis (P=0.6409), tumor location (P=0.3520), differentiated degree (P=0.5608), pathological (histological) type (P=0.4885), and response to treatment (P=0.9859). The VEGF load per platelet (VEGFPLT) levels were not correlated with sex, age, primary tumor site, and pathological type in NSCLC patients (all P>0.05). The median survival time of progression-free survival (PFS) was 6.407 and 5.29 months in the low and high groups, respectively, when using 280 pg/mL VEGF level as the cutoff point (P=0.024). Conclusion In conclusion, the serum VEGF levels were found to be a poor prognostic biomarker for the efficacy of platinum-based chemotherapy in terms of PFS, but it was not shown to be a suitable predictive marker for clinical response to platinum-based chemotherapy.

Abstract
The modern process of discovering candidate molecules in early drug discovery phase includes a wide range of approaches to extract vital information from the intersection of biology and chemistry. A typical strategy in compound selection involves compound clustering based on chemical similarity to obtain representative chemically diverse compounds (not incorporating potency information). In this paper, we propose an integrative clustering approach that makes use of both biological (compound efficacy) and chemical (structural features) data sources for the purpose of discovering a subset of compounds with aligned structural and biological properties. The datasets are integrated at the similarity level by assigning complementary weights to produce a weighted similarity matrix, serving as a generic input in any clustering algorithm. This new analysis work flow is semi-supervised method since, after the determination of clusters, a secondary analysis is performed wherein it finds differentially expressed genes associated to the derived integrated cluster(s) to further explain the compound-induced biological effects inside the cell. In this paper, datasets from two drug development oncology projects are used to illustrate the usefulness of the weighted similarity-based clustering approach to integrate multi-source high-dimensional information to aid drug discovery. Compounds that are structurally and biologically similar to the reference compounds are discovered using this proposed integrative approach.

Abstract
Background Basic fibroblast growth factor (bFGF) is known to stimulate angiogenesis and thus to influence the proliferation, migration and survival of tumor cells. Many studies examined the relationship between human bFGF overexpression and survival in lung cancer patients, but the results have been mixed. To systematically summarize the clinical prognostic function of bFGF in lung cancer, we performed this systematic review with meta-analysis. Method Studies were identified by an electronic search of PubMed, EMBASE, China National Knowledge Infrastructure and Wanfang databases, including publications prior toAugust 2014. Pooled hazard ratios (HR) for overall survival (OS) were aggregated and quantitatively analyzed by meta-analysis. Results Twenty-two studies (n = 2154) were evaluated in the meta-analysis. Combined HR suggested that bFGF overexpression had an adverse impact on survival of patients with lung cancer(HR = 1.202,95%CI, 1.022–1.382). Our subgroup analysis revealed that the combined HR evaluating bFGF expression on OS in operable non-small cell lung cancer (NSCLC) was 1.553 (95%CI, 1.120–1.986); the combined HR in small cell lung cancer (SCLC) was 1.667 (95%CI, 1.035–2.299). There was no significant impact of bFGF expression on survival in advanced NSCLC. Conclusion This meta-analysis showed that bFGF overexpression is a potential indicator of worse prognosis for patients with operable NSCLC and SCLC, but is not associated with outcome in advanced NSCLC. The data suggests that high bFGF expression is highly related to poor prognosis. Nevertheless,more high-quality studies should be performed in order to provide additional evidence for the prognostic value of bFGF in lung cancer.

Circulating Thrombospondin-2 and FGF-2 in Patients with Advanced Non-small Cell Lung Cancer: Correlation with Survival. ADVANCES IN EXPERIMENTAL MEDICINE AND BIOLOGY 2015; 833:9-14.

Abstract
Thrombospondin-2 (TSP-2) is an endogenous negative regulator of vascularization in human cancer. TSP-2 regulates angiogenesis through binding and sequestration of the proangiogenic fibroblast growth factor-2 (FGF-2). However, it is unclear whether TSP-2 and FGF-2 are related to prognosis in non-small cell lung cancer (NSCLC). To study this issue, we measured serum (Elisa) levels of TSP-2 and FGF-2 in 40 NSCLC patients (before chemotherapy) and 22 healthy subjects. Both TSP-2 and FGF-2 concentrations were elevated in the NSCLC group compared with control (TSP-2: 26.72±8.00 vs. 18.64±5.50 ng/ml, p=0.002; FGF-2: 11.90±5.80 vs. 7.26±3.90 pg/ml, p=0.01). Receiver-operating characteristic (ROC) curves were applied to find the cut-off serum levels of TSP-2 and FGF-2 (NSCLC vs. healthy: TSP-2=15.09 ng/ml, FGF-2=2.23 pg/ml). Patients before treatment with the TSP-2 level<24.15 ng/ml had a median survival of 23.7 months, but those with TSP-2>24.15 ng/ml had only 9 months' median survival (p=0.007). Patients with FGF-2 level>11.21 pg/ml had significantly shorter survival than patients with FGF-2<11.21 pg/ml (7.5 months vs. 16 months, p=0.034). We conclude that NSCLC patients have higher serum concentrations of TSP-2 and FGF-2 than healthy people. High levels of TSP-2 and FGF-2 may predict worse survival.

Abstract
Ascites can be caused by many kinds of diseases. Patients with undetermined ascites represent a diagnostic challenge. The aims of this study were to determine the diagnostic value of vascular endothelial growth factor (VEGF) in differentiation of malignant ascites from benign ascites and to investigate the clinical value of ascitic VEGF as an independent prognostic parameter. The study included 462 consecutive patients with malignant ascites and 550 patients with benign ascites, VEGF level in ascites were determined by a sandwich enzyme-linked immunosorbent assay. The survival rate was calculated by the Kaplan-Meier method and the log-rank test. Multivariate survival analysis was performed using the Cox hazards model. In our study, we found VEGF levels in malignant ascites (676.59 ± 303.86 pg/ml) were significantly higher than those in benign ascites (218.37 ± 98.15 pg/ml) (P < 0.001). Meanwhile, we also found that VEGF levels in malignant ascites from patients with ovarian cancer were higher than those with other cancers. Areas under the receiver operating characteristic (ROC) curves of ascitic VEGF was 0.940. At a cutoff value of 319.5 pg/ml, VEGF yielded a sensitivity of 89.2 % and a specificity of 88.4 %. Patients associated with the high-level VEGF value (≥613.38 pg/ml) in malignant ascites exhibited poor mean survival rates (8.3 ± 0.52 vs 15.11 ± 0.66 months, P < 0.001). In a multivariate Cox regression model, higher ascitic VEGF was an independent prognostic factor for overall survival. Planned subgroup analysis was performed for patients with tumor node metastasis (TNM) stage I. In the univariate analysis, only ascitic VEGF was associated with overall survival. VEGF was found to have a highly accurate sensitivity and specificity, suggesting that it could be considered as a new biomarker to differentiate malignant ascites from the benign one. The high level of VEGF value in malignant ascites may be used as an independent prognostic factor in patients with all stages of cancer.

Abstract
Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, and can be further classified as nonsquamous carcinoma (including adenocarcinoma, which accounts for 40 % of NSCLCs) and squamous NSCLC, which makes up 30 % of NSCLC cases. The emergence of inhibitors of epidermal growth factor receptors, anaplastic lymphoma kinase, and vascular endothelial growth factors (VEGF) in the last decade has resulted in steady improvement in clinical outcomes for patients with advanced lung adenocarcinoma. However, improvements in the survival of patients with squamous NSCLC have remained elusive, presenting an urgent need for understanding and investigating therapeutically relevant molecular targets, specifically in squamous NSCLC. Although anti-VEGF therapy has been studied in squamous NSCLC, progress has been slow, in part due to issues related to pulmonary hemorrhage. In addition to these safety concerns, several phase III trials that initially included patients with squamous NSCLC failed to demonstrate improved overall survival (primary endpoint) with the addition of antiangiogenic therapy to chemotherapy compared with chemotherapy alone. Angiogenesis is an established hallmark of tumor progression and metastasis, and the role of VEGF signaling in angiogenesis is well established. However, some studies suggest that, while inhibiting VEGF signaling may be beneficial, prolonged exposure to VEGF/VEGF receptor (VEGFR) inhibitors may allow tumor cells to utilize alternative angiogenic mechanisms and become resistant. As a result, agents that target multiple angiogenic pathways simultaneously are also under evaluation. This review focuses on current and investigational antiangiogenic targets in squamous NSCLC, including VEGF/VEGFRs, fibroblast growth factor receptors, platelet-derived growth factor receptors, and angiopoietin. Additionally, clinical trials investigating VEGF- and multi-targeted antiangiogenic therapies are discussed.

Abstract
To date therapeutic options for squamous cell lung cancer patients remain scarce because no druggable targets have been identified so far. Aberrant signaling by FGFs (fibroblast growth factors) and FGFRs (fibroblast growth factors receptors) has been implicated in several human cancers and, particularly, in squamous non-small cell lung cancer (NSCLC). FGFR gene amplifications, somatic missense mutations, chromosomal translocations are the most frequent mechanisms able to induce aberrant activation of this pathway. Data from literature have established that the presence of an aberrant FGFR signaling has to be considered a possible negative prognostic factor but predictive of potential sensitivity to FGFR inhibitors. In the last years, clinical research efforts allowed to identify and evaluate promising FGFR inhibitors, such as monoclonal antibodies, ligand traps, non-selective or selective tyrosine kinase inhibitors. This review summarizes the current knowledge about FGFR alterations in NSCLC and the relative inhibitors in development, in particular in squamous NSCLC.

Abstract
With the introduction of targeted agents primarily applicable to non-small cell lung cancer (NSCLC) of adenocarcinoma histology, there is a heightened unmet need in the squamous cell carcinoma population. Targeting the angiogenic fibroblast growth factor (FGF)/FGF receptor (FGFR) signaling pathway is among the strategies being explored in squamous NSCLC; these efforts are supported by growth-promoting effects of FGF signaling in preclinical studies (including interactions with other pathways) and observations suggesting that FGF/FGFR-related aberrations may be more common in squamous versus adenocarcinoma and other histologies. A number of different anti-FGF/FGFR approaches have shown promise in preclinical studies. Clinical trials of two multitargeted tyrosine kinase inhibitors are restricting enrollment to patients with squamous NSCLC: a phase I/II trial of nintedanib added to first-line gemcitabine/cisplatin and a phase II trial of ponatinib for previously treated advanced disease, with the latter requiring not only squamous disease but also a confirmed FGFR kinase amplification or mutation. There are several ongoing clinical trials of multitargeted agents in general NSCLC populations, including but not limited to patients with squamous disease. Other FGF/FGFR-targeted agents are in earlier clinical development. While results are awaited from these clinical investigations in squamous NSCLC and other disease settings, additional research is needed to elucidate the role of FGF/FGFR signaling in the biology of NSCLC of different histologies.

Abstract
Currently, there is no serum marker that is routinely recommended for lung cancer. Therefore, the aim of the present study was to demonstrate that plasma vascular endothelial growth factor 165 (VEGF 165) may be a potential marker for advanced lung cancer. Lung cancer is the leading cause of cancer-related mortality worldwide, therefore, it is important to develop novel diagnostic techniques. The present prospective case control study included two groups of patients; a control group of healthy volunteers and a second group of patients with advanced non-small cell lung cancer (NSCLC). The plasma VEGF 165 levels were measured at baseline by ELISA prior to the first-line gemcitabine-cisplatin regimen. The high VEGF 165 expression level cut-off was >703 pg/ml, and the primary endpoint was used to compare the plasma VEGF 165 levels between the NSCLC patients and the control group subjects. The secondary endpoint was used to identify the correlations between high VEGF 165 levels and; clinical response (CR), progression-free survival (PFS) and overall survival (OS) in the advanced NSCLC patients. In total, patients with advanced NSCLC (n=35) were compared with a control group of age- and gender-matched healthy subjects (n=34). The follow-up period was between Oct 2009 and Oct 2012, with a median follow-up time of 10.5 months. The median plasma VEGF 165 level was 707 pg/ml in the NSCLC patients versus 48 pg/ml in the healthy control subjects (P<0.001). However, no significant correlation was found between the plasma VEGF 165 levels and CR (P<0.5), median PFS (P=1.00) or OS (P=0.70). Therefore, it was concluded that plasma VEGF 165 may serve as a potential diagnostic marker for advanced NSCLC.

Abstract
Purpose Vascular endothelial growth factor (VEGF)-A, VEGF165b, interleukin (IL)-1β, and transforming growth factor (TGF)-β1 are known to influence tumor angiogenesis. Clinical implications of these cytokines need to be elucidated. Materials and Methods Using clinical data and baseline serum samples of 140 consecutive patients with advanced non-small cell lung cancer who received platinum-based combination chemotherapy, we investigated the association among serum cytokine levels, treatment outcomes, as well as leukocyte and platelet counts. Results The median age of patients was 64 years (range, 26 to 86 years). The male to female ratio was 104:36. High TGF-β1 and IL-1β levels were associated with shorter progression-free survival, and high VEGF-A and IL-1β levels were associated with shorter overall survival in the univariate analysis. VEGF165b was not related to the treatment outcomes. Leukocytosis and thrombocytosis were associated with shorter overall survival. The multivariate analysis demonstrated that VEGF-A, IL-1β, and leukocytosis were significant prognostic factors (p=0.0497, p=0.047, and p<0.001, respectively). Leukocytosis was not associated with recent pneumonia (p=0.937) and correlated with VEGF-A (p<0.001) and TGF-β1 (p=0.020) levels. Conclusion Serum VEGF-A, TGF-1β, and IL-1β levels, in addition to leukocyte and platelet counts, are shown to be associated with clinical outcomes. Leukocyte and platelet counts are correlated with serum VEGF-A and TGF-β1 levels.

Abstract
BACKGROUND Some patients diagnosed with early-stage lung cancer and treated according to standard care survive for only a short period of time, while others survive for years for reasons that are not well understood. Associations between markers of inflammation and survival from lung cancer have been observed. MATERIALS AND METHODS Here, we investigate whether circulating levels of 77 inflammatory markers are associated with long versus short survival in stage I and II lung cancer. Patients who had survived either <79 weeks (~1.5 years) (short survivors, SS) or >156 weeks (3 years) (long survivors, LS) were selected from a retrospective population-based study. Logistic regression was used to calculate adjusted odds ratios (ORs) and corresponding 95% confidence intervals (CIs). The false discovery rate was calculated to adjust for multiple testing. RESULTS A total of 157 LS and 84 SS were included in this analysis. Thirteen markers had adjusted OR on the order of 2- to 5-fold when comparing the upper and lower quartiles with regard to the odds of short survival versus long. Chemokine CCL15 [chemokine (C-C motif) ligand 15] was the most significant marker associated with increased odds of short survival (ORs = 4.93; 95% CI 1.90-12.8; q-value: 0.042). Smoking and chronic obstructive pulmonary disease were not associated with marker levels. CONCLUSIONS Our results provide some evidence that deregulation of inflammatory responses may play a role in the survival of early-stage lung cancer. These findings will require confirmation in future studies.

Abstract
PURPOSE Vascular endothelial growth factor (VEGF) is considered as the best-validated key regulator of angiogenesis, while the prognostic role of circulating VEGF in lung cancer remains controversial. We conducted a meta-analysis to evaluate the prognostic role of circulating VEGF. METHODS Nineteen studies with a total number of 2,890 patients were analyzed in our meta-analysis. Hazard ratios (HRs) and their 95 % confidence intervals (CIs) were used to quantify the predictive ability of circulating VEGF on survival. RESULTS The pooled HR of all 17 studies evaluating overall survival (OS) was 1.29 (95 % CI 1.19-1.40, p < 0.001), indicating high circulating VEGF predicted poor OS. When grouped by disease stages, the pooled HRs were 0.97 (95 % CI 0.47-1.47, p < 0.001) for operable stage and 1.34 (95 % CI 1.18-1.49, p < 0.001) for inoperable stage. The pooled HRs were 1.28 (95 % CI 1.15-1.42, p < 0.001) for serum and 1.31 (95 % CI 1.13-1.49, p < 0.001) for plasma, when categorized by blood sample. Meta-analysis of circulating VEGF related to progression-free survival (PFS) was performed in 7 studies, and the pooled HR was 1.03 (95 % CI 0.96-1.09). CONCLUSIONS Our results indicate that high level of circulating VEGF predicts poor OS in lung cancer, yet it does not predict poor PFS.

Abstract
Despite major advances in cancer therapeutics, the prognosis for lung cancer patients is still poor and the median survival for patients presenting with advanced non-small cell lung cancer (NSCLC) is only 8-10 months. Angiogenesis is an important biological process and a relatively early event during lung cancer pathogenesis. Anti-angiogenic agents are used in treating patients with NSCLC, and their molecular biomarkers are also being assessed to predict response. A better understanding of the biology of angiogenesis in NSCLC may reveal new targets for treating this malignancy. In this article, we review the expression and prognostic impact of the angiogenic growth factors, vascular endothelial growth factor and basic fibroblast growth factor, in NSCLC.

Abstract
INTRODUCTION Eicosanoids, including PGE-2 and 5-HETE, can increase levels of plasma vascular endothelial growth factor (VEGF). Overexpression of COX-2 or 5-LOX increases levels of PGE-2 and 5-HETE, respectively. Elevated levels of VEGF are common in patients with non-small cell lung cancer (NSCLC). We prospectively measured VEGF in serum collected from patients enrolled in Cancer and Leukemia Group B 30203, a randomized phase II study of eicosanoid modulation in addition to chemotherapy in patients with advanced NSCLC, to determine whether these levels had prognostic significance and whether they correlated with COX-2 expression and/or responded to inhibition of COX-2 or 5-LOX. METHODS Pre- and post-treatment serum was collected from patients enrolled in CALGB 30203. Serum VEGF levels were determined using enzyme-linked immunosorbent assay methodology. Statistical analyses were performed to determine the correlation between pretreatment serum VEGF levels and time of overall survival. Pretreatment formalin fixed tissue was stained for 5-LOX and COX-2 by immunohistochemistry. RESULTS The median baseline VEGF level was 502 pg/ml (range, 55-3453 pg/ml). Dichotomized serum VEGF levels at median inversely correlated with survival time (p = 0.008), as did VEGF levels as a continuous variable in multivariate analysis (p = 0.035). VEGF levels were significantly correlated neither with baseline COX-2 expression (Pearson r = 0.1524, p = 0.271) nor with 5-LOX expression. Treatment with COX-2 or 5-LOX inhibitors did not alter the levels. CONCLUSION These data indicate that elevated serum VEGF is a negative prognostic variable in NSCLC. VEGF levels are neither correlated with baseline tumor COX-2 expression nor do they respond to COX-2 and/or 5-LOX inhibition plus chemotherapy.

Abstract
Despite recent progress in the treatment on non-small cell lung cancer (NSCLC), outcomes remain suboptimal. Treatment advances that target the epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) signaling pathways highlight the need to understand the multiple convergent growth factor signaling pathways involved in the pathogenesis of NSCLC. Signaling through fibroblast growth factors (FGF), long recognized for its pro-angiogenic activity, has recently emerged as a contributing factor in the pathogenesis and progression of NSCLC through an autocrine signaling loop. In addition, this pathway may function as a mechanism of resistance to anti-EGFR and anti-VEGF treatment. Clinical experience with FGF receptor (FGFR) inhibitors is mounting, and more specific inhibitors of this signaling pathway are in development. This review describes the structure of the FGF signaling pathway, delineates its dual roles in angiogenesis and proliferation in NSCLC, evaluates FGF ligand and receptor expression as prognostic biomarkers in NSCLC, and discusses the development of FGF pathway inhibitors for the treatment of lung malignancies.

Abstract
BACKGROUND Circulating angiogenic factors (CAF) have been shown as therapeutic targets and prognostic biomarkers in metastatic colorectal cancer. However, their correlation with circulating tumor cells (CTC) is unknown, as is their role as prognostic biomarkers in patients amenable for curative resection. METHODS Preoperative blood samples were collected in patients undergoing potentially curative resection of colorectal liver metastases. Serum levels of eight CAF and CTC were analyzed by using ELISA and CK20 RT-PCR, respectively. Prognostic factors were identified by a Cox proportional hazards model. RESULTS A total of 107 patients were eligible for final analyses. Circulating levels of PlGF, EGF, and bFGF were increased, whereas PDGF-A and Ang-1 levels were decreased in patients compared with healthy control subjects. CTC were detected in 36 of 63 patients (57%) and were associated with significantly lower levels of EGF and bFGF. On univariate analyses, multiple metastases (p = 0.04), a MSKCC risk score >2 (p = 0.004), and detection of CTC (p = 0.05) were associated with disease recurrence. Multivariate analysis, including the panel of eight CAF, revealed a MSKCC score >2 [hazard ratio (HR), 2.01; 95% confidence interval (CI), 1.11-3.82; p = 0.02] and low levels of circulating PlGF (HR, 0.26; 95% CI, 0.08-0.81; p = 0.02) as independent predictors of poor recurrence-free survival. CONCLUSIONS CAF may indicate patients who are at high risk for disease recurrence. The notion that CAF may identify patients who benefit from adjuvant therapy or antiangiogenic agents warrants further investigation.

Abstract
Functionally, the pancreas consists of two types of tissues: exocrine and endocrine. Exocrine pancreatic disorders mainly involve acute and chronic pancreatitis. Acute pancreatitis typically is benign, while chronic pancreatitis is considered a risk factor for developing pancreatic cancer. Pancreatic carcinoma is the fourth leading cause of cancer related deaths worldwide. Most pancreatic cancers develop in the exocrine tissues. Endocrine pancreatic tumors are more uncommon, and typically are less aggressive than exocrine tumors. However, the endocrine pancreatic disorder, diabetes, is a dominant cause of morbidity and mortality. Importantly, different growth factors and their receptors play critical roles in pancreatic pathogenesis. Hence, an improved understanding of how various growth factors affect pancreatitis and pancreatic carcinoma is necessary to determine appropriate treatment. This chapter describes the role of different growth factors such as vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF), platelet derived growth factor (PDGF), fibroblast growth factor (FGF), epidermal growth factor (EGF), and transforming growth factor (TGF) in various pancreatic pathophysiologies. Finally, the crosstalk between different growth factor axes and their respective signaling mechanisms, which are involved in pancreatitis and pancreatic carcinoma, are also discussed.

Abstract
PURPOSE The low-dose metronomic chemotherapy was reported to inhibit directly tumor angiogenesis or VEGF secretion. The study aimed to seek for this effect of system chemotherapy by observing the changes in serum levels of angiogenic cytokines during treatment and assessing their value in monitoring the advanced breast cancer. METHODS In sixty-one patients with advanced breast cancer, serum levels of vascular endothelial growth factor (VEGF) and endostatin (ES) were compared at baseline (B0), after one cycle (B1), after 3 cycles (B3), and after 5-6 cycles (B5-6) of system chemotherapy using a quantitative ELISA. Data were correlated with treatment response and total survival. RESULTS The response to chemotherapy did not correlate with serum VEGF level before therapy or after one cycle, but the changes in VEGF levels after 3 cycles and 5-6 cycles showed good association with clinical responses, i.e., the patients with disease control had a decreased VEGF value, whereas the progressive patients had an increased value. The Cox proportional hazard model revealed that a normalized VEGF level after therapy and an increase in VEGF level after 5-6 cycles were independent predictors for survival. CONCLUSIONS System chemotherapy for advanced breast cancer lead to a significant decrease in serum VEGF level in patients with disease control, and this anti-VEGF efficacy may be mainly due to the reduction in tumor burden. Sequential measurement of serum VEGF could be useful for evaluating treatment efficacy and prognosis.

Abstract
PURPOSE Fibroblast growth factor 2 (FGF2; basic fibroblast growth factor, b-FGF) and its main receptor FGFR-1 are important in both hemangiogenesis and lymphangiogenesis. Murine studies have indicated a close interplay between both FGF2 and platelet-derived growth factor-B (PDGF-B) as well as FGF2 and vascular endothelial growth factor-3 (VEGFR-3). This study investigates the prognostic impact of FGF2 and FGFR-1 in tumor cells and tumor stroma of resected non-small cell lung carcinomas (NSCLC) and explores the importance of their coexpression with VEGFR-3 or PDGF-B. METHODS Tumor tissue samples from 335 resected patients with stage I to IIIA NSCLC were obtained and tissue microarrays were constructed from duplicate cores of tumor cells and tumor-related stroma from each specimen. Immunohistochemistry was used to evaluate the expression of the molecular markers FGF2, FGFR-1, VEGFR-3, and PDGF-B. RESULTS In univariate analyses, high tumor cell FGF2 expression (p = 0.015) was a negative prognostic indicator for disease-specific survival. In tumor stroma, high FGF2 (p = 0.024) expression correlated with good prognosis. In multivariate analyses, high expression of FGF2 in tumor cells (p = 0.038) was an independent negative prognostic factor whereas increased FGF2 in stroma (p = 0.015) was a positive prognosticator. Tumor cell coexpressions of FGF2/VEGFR-3 (p < 0.001) and FGFR-1/PDGF-B (p = 0.002) were significant indicators of poor prognosis. CONCLUSIONS Expression of FGF2 in tumor cells is an independent negative prognostic factor, and the coexpressions of FGF2/VEGFR-3 and FGFR-1/PDGF-B are strongly associated with poor survival in NSCLC patients.

Abstract
The characteristic changes in cancer process are assumed to be genetic alterations about the imbalance of cell proliferation and apoptotic cell death. This study was conducted to determine the value of the circulating vascular endothelial growth factor (VEGF) and Bcl-2 in patients with advanced stage non-small cell lung cancer (NSCLC). These serum factors were measured of 52 NSCLC patients pathologically verified on before and after chemotherapy in comparison with 16 healthy controls by using ELISA method. Both of the serum levels of VEGF (p = 0.015) and Bcl-2 (p < 0.001) were increased significantly in NSCLC patients compared with the healthy controls. No statistically significant relationships between investigated elevated serum parameters and various characteristics of patients and disease such as stage and tumor burden were determined. Likewise, we also found no correlation between serum VEGF and Bcl-2. Cytotoxic therapy of patients was accompanied by unchanged serum levels of serum factors. The median survival of all patients was 27 weeks and one-year survival rate was 22.4 percent. With the median serum levels as the cut-off value, patients were divided into high- and low-serum parameter groups. While we found that patients' performance status (p < 0.0001), serum LDH level (p = 0.0002), response to chemotherapy (p = 0.0023), and stage of the disease (p = 0.0085) were prognostic factors for survival, serum VEGF (p = 0.48) and Bcl-2 (p = 0.91) levels were determined as ineffective on survival in patients with advanced NSCLC. In conclusion, our data suggest that these serum factors, VEGF and Bcl-2, are useful diagnostic factors, not predictive and prognostic markers for overall survival in advanced NSCLC patients.

Drug Resist Updat 2009; 12:95-102. [PMID: 19501013 DOI: 10.1016/j.drup.2009.05.001] [Citation(s) in RCA: 48] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2009] [Revised: 05/09/2009] [Accepted: 05/11/2009] [Indexed: 01/25/2023]
Abstract
The EGFR has been targeted through the development of selective tyrosine kinase inhibitors (TKIs) that have proven effective in a subset of non-small cell lung cancer (NSCLC) patients, many bearing gain-of-function EGFR mutations or egfr gene amplification. However, the majority ( approximately 80-90%) of NSCLC patients do not respond to EGFR-specific TKIs and a high rate of acquired resistance to these therapeutics is observed in those that do respond. Thus, EGFR-specific TKIs will not, as single agents, make a high impact on overall lung cancer survival. A number of studies support the activities of other receptor tyrosine kinase pathways including cMet, IGF-1R and FGFRs as mechanisms for both intrinsic and acquired resistance to EGFR TKIs. While the role of cMet and IGF-1R signaling systems as mechanisms of resistance to EGFR TKIs has been widely reviewed in recent years, the potential role of FGFR-dependent signaling as a mechanism for EGFR TKI resistance has more recently emerged and will be highlighted herein. Due to the high degree of homology of FGFRs with VEGFRs and PDGFRs, FGFR-active TKIs already exist via development of VEGFR-targeted TKIs as angiogenesis inhibitors. Thus, these agents could be rapidly advanced into clinical investigations as FGFR inhibitors, either alone or in combination with TKIs selective for EGFR, cMet or IGF-1R as a means to expand the spectrum of NSCLC patients that can be effectively targeted with TKI-directed therapies.

The positive correlation between gene expression of the two angiogenic factors: VEGF and BMP-2 in lung cancer patients. Lung Cancer 2009; 66:319-26. [PMID: 19324447 DOI: 10.1016/j.lungcan.2009.02.020] [Citation(s) in RCA: 54] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2008] [Revised: 02/17/2009] [Accepted: 02/22/2009] [Indexed: 11/24/2022]
Abstract
Lung cancer is a particular challenge in oncology. More than 1 million new cases occur worldwide every year and despite many clinical trials and modern diagnostic techniques, long-term survival rate has only marginally improved. The aim of the current research is to explore new molecular prognostic factors and identify new targets for anticancer therapy. Current evidence shows that angiogenesis is controlled by several angiogenic factors including VEGF and BMP-2. It has been also demonstrated that VEGF plays a key role in this process that is essential in carcinogenesis. Our study has shown that the expressions of the VEGF, BMP-2 and BMP-4 mRNAs were significantly higher (7.1-fold, 25.6-fold and 2.3-fold, respectively) in lung cancer samples than in adjacent normal lung tissues (real-time RT-PCR). Analysis based on the Pearson's correlation coefficient indicated the positive correlation between VEGF and BMP-2 gene expression, whereas no significant correlation between VEGF and BMP-4 gene expression was found. The mean+/-standard deviation serum level of VEGF was 423+/-136 pg/ml. Significant differences in the serum levels of VEGF between patients with T1 tumors and patients with T2, T3 or T4 tumors were observed. Patients with T2, T3 and T4 tumors, respectively, had 1.6-fold, 1.8-fold and 2.3-fold greater serum levels of VEGF than their peers with T1 tumors. In current study patients homozygous for the 936T allele of the +936C/T VEGF gene polymorphism had 12-fold lower VEGF gene expression and 1.3-fold lower VEGF serum level than patients homozygous for the 936C allele. In conclusion, our findings underline the importance of the two angiogenic factors namely VEGF and BMP-2 as well as +936C/T VEGF gene polymorphism in the evaluation of lung cancer patients.

Abstract
The aim of the present study was to evaluate the levels of VEGF, 8-isoprostane and TNF-alpha in EBC and serum of patients with primary lung cancer prior to the initiation of any treatment, in order to evaluate their possible diagnostic role. Furthermore, associations between VEGF, 8-isoprostane and TNF-alpha levels in EBC and serum with clinicopathologic factors were investigated. We enrolled 30 patients with lung cancer (mean age 65.2+/-10.5 years) and 15 age and gender-matched healthy smokers as controls. Serum and EBC were collected before any treatment. TNF-alpha, VEGF and 8-isoprostane levels in EBC and serum were analyzed by an immunoenzymatic method (ELISA). A statistically significant difference was observed between lung cancer patients and the control group regarding the values of TNF-alpha, both in EBC (52.9+/-5.0 pg/ml vs. 19.4+/-3.9 pg/ml, p<0.0001) and serum (44.5+/-6.3 pg/ml vs. 22.2+/-4.3 pg/ml, p=0.035). Moreover, EBC VEGF levels were higher in patients with T3-T4 tumor stage compared to T1-T2 (9.3+/-2.8 pg/ml vs. 2.3+/-0.7pg/ml, p=0.047). A statistically significant correlation was also observed between serum and EBC values of VEGF (r=0.52, p=0.019). In addition, serum levels of VEGF were higher in lung cancer patients than in controls (369.3+/-55.1 pg/ml vs. 180.5+/-14.7 pg/ml, p=0.046). VEGF serum levels were also found higher in patients with advanced stage of disease (IIIB-IV) and distant nodal metastasis (N2-N3). No differences were observed in 8-isoprostane in EBC between lung cancer patients and controls. In contrast, serum 8-isoprostane levels were higher in lung cancer patients compared to controls (24.9+/-3.6 pg/ml vs. 12.9+/-1.6 pg/ml, p=0.027) and were higher in patients with advanced disease. All three biomarkers presented acceptable reproducibility in the EBC on two consecutive days. In conclusion, we have shown that TNF-alpha, VEGF and 8-isoprostane are elevated in the serum of lung cancer patients and increased serum VEGF and 8-isoprostane levels are related to advanced disease. In EBC, increased TNF-alpha levels were observed in lung cancer patients, whereas increased VEGF levels were observed in advanced T-stage. Further longitudinal studies are warranted for the evaluation of the prognostic role of these biomarkers in lung cancer.

Abstract
Tumor growth and metastasis depend on angiogenesis, and the vascular endothelial growth factor (VEGF) is known to be one of the most important angiogenic factors although the knowledge about its receptors is limited. We, therefore, investigated the treatment-related changes both in the level of the soluble vascular endothelial growth factor receptor-1 (sVEGFR-1) in the serum by ELISA and the expression of VEGFR-1 in cancer tissues by immunohistochemistry. The serum levels were studied in 38 lung cancer patients, and 55 control subjects (21 benign disease and 34 healthy subjects) before the chemotherapy. The treatment-related changes in serum sVEGFR-1 were evaluated in 15 patients 24 and 48 hours after treatment. In addition to serum analysis, the tissue expressions were evaluated in 32 patients before treatment. The treatment-related changes in tissue VEGFR-1 expressions were evaluated in only 12 patients 24 hours after treatment. We observed no significant difference in terms of serum sVEGFR-1 levels between malignant and nonmalignant groups (p > 0.05). There were no significant differences in the levels of sVEGFR-1 before and after treatment (p > 0.05). However, there was a significant difference between sVEGFR-1 levels in the groups (regressive, stable, progressive) classified according to the response to therapy (p = 0.043). A significant difference also was present between the expression levels of tissue VEGFR-1 in the same groups (p = 0.037). As a conclusion, we suggest that prechemotherapy sVEGFR-1 can be helpful for prediction of long-term response to therapy, but it should be studied in larger groups to elucidate its benefit in clinics.

Abstract
Lung cancer is the leading cause of cancer-related death among men and women in the United States. Approximately 80-85% of lung cancer cases are non-small-cell lung cancer (NSCLC), and approximately 65% of these patients have advanced-stage (IIIB/IV) disease at diagnosis. The median survival for patients with advanced-stage NSCLC treated with platinum-based chemotherapy is a disappointing 8-10 months. This article reviews the current status of chemotherapy in patients with a good functional status and evaluates the treatments in terms of efficacy, toxicity, survival, and impact on quality of life in the first-line treatment. Biologic agents such as bevacizumab and erlotinib have been investigated in phase III trials in the first- and second-line setting. These agents could play a role in select patient populations. This article also highlights some of the more promising new strategies, such as advances in pharmacogenomics and immune-based therapy. There is a clear need for improvement in the current standard of care. Well-designed clinical trials with appropriate patient selection, as well as continued efforts in translational research and pharmacogenomics, are crucial for progress in this disease.

Abstract
BACKGROUND Since growth and de novo generation of cerebrovascular malformations were demonstrated, a strictly congenital model cannot be further supported as unique factor in the pathogenesis of cerebral arteriovenous malformations (AVMs). Vascular endothelial growth factor (VEGF) has previously been demonstrated to be highly expressed in AVMs by immunohistochemical methods. However, systemic VEGF levels have not been analysed previously. This study aimed to investigate VEGF plasma concentrations as a possible plasma marker for neovascularization in patients with cerebral AVMs compared to healthy controls. METHODS The study included 17 patients with cerebral AVMs and 40 healthy controls. VEGF plasma concentrations were measured by a specific enzyme immuno-assay. RESULTS VEGF plasma concentrations were significantly higher in patients with cerebral AVMs (mean 140.9 pg/ml, SD 148.5 pg/ml and median 63.0 pg/ml) compared to a healthy control group (mean 44.7 pg/ml, SD 36.4 pg/ml and median 35.0 pg/ml), p = 0.0003. CONCLUSIONS Our findings suggest that VEGF plasma concentrations might play a role in the pathogenesis of cerebral AVMs. Further studies are necessary and would contribute to an improved understanding of the pathogenesis of cerebral AVMs.

Abstract
The activity of growth factors is crucial for tumor progression. We previously characterized a secreted fibroblast growth factor-binding protein (FGF-BP1) as a chaperone molecule, which enhances the biological functions of FGFs by releasing FGFs from the extracellular matrix. Here, we characterize the frequency and pattern of FGF-BP1 expression during the malignant progression of pancreas and colorectal carcinoma. For this, we generated monoclonal antibodies that detect FGF-BP1 protein in formalin-fixed, paraffin-embedded tissues and applied in situ hybridization to detect FGF-BP1 mRNA in adjacent tissue sections. FGF-BP1 protein and mRNA were found up-regulated (>70% positive) in parallel (r = 0.70, P < 0.0001) in colon adenoma (n = 9) as well as primary (n = 46) and metastatic (n = 71) colorectal cancers relative to normal colon epithelia (all P < 0.0001, versus normal). Similarly, pancreatitis (n = 17), pancreatic intraepithelial neoplasia (n = 80), and pancreatic adenocarcinoma (n = 67) showed a significant up-regulation of FGF-BP1 compared with normal pancreas (n = 42; all P < 0.0001, relative to normal). Furthermore, the biological activity of FGF-BP1 is neutralized by one of the antibodies, suggesting the potential for antibody-based therapeutic targeting. We propose that the up-regulation of the secreted FGF-BP1 protein during initiation of pancreas and colon neoplasia could make this protein a possible serum marker indicating the presence of high-risk premalignant lesions.

Abstract
BACKGROUND Due to a dismal prognosis of advanced lung cancer, novel screening tools and more effective treatments are clearly needed. Lately, an increasing number of tumour-released angiogenic cytokines which affect vessel formation, tumour growth, invasion, and metastasis have been identified. Vascular endothelial growth factors (VEGFs) and basic fibroblast growth factor (bFGF) are among the most important angiogenic factors. Based on available literature, we have explored the mechanisms of angiogenesis and its prognostic significance in non-small cell lung cancer, estimated by microvessel density (MVD) and the presence of VEGF and bFGF in the tumour and blood from NSCLC patients. METHODS Several comprehensive Pubmed searches for the period January 1993 to May 2005 were performed using strategic combinations of the terms non-small cell lung cancer, angiogenesis, vascular endothelial growth factor, basic fibroblast growth factor, tumour expression, microvessel density, circulating, and serum. RESULTS NSCLC neoangiogenesis, as measured by MVD, and tumour expression of VEGF are poor prognostic factors for survival (MVD, HR 1.8-2.0; VEGF, HR 1.5). bFGF tumour expression is also associated with poor survival and more aggressive disease. When evaluating the prognostic impact of elevated VEGF levels in blood, 10 of 16 studies (63%) indicated a negative prognostic impact. Of five studies on the prognostic value of circulating bFGF, three studies reported a negative prognostic impact, while one indicated bFGF as a good prognostic factor and one was inconclusive. CONCLUSION Angiogenic factors are poor prognostic indicators for tumour aggressiveness and survival in NSCLC. Assessments of circulating levels of VEGF and possibly bFGF may be valuable future tools for treatment planning and monitoring of treatment effect and relapse. First, however, these blood tests need to be standardised and validated in large-scale prospective clinical trials.

Abstract
High serum levels of vascular endothelial growth factor (VEGF) are a poor prognostic factor for patients with advanced non-small-cell lung cancer (NSCLC). We have previously shown that low-dose interleukin (IL)-2 and 13-cis retinoic acid (RA) decreased VEGF and improved the immune function of patients with advanced tumors treated with chemotherapy. The primary end point of this study was to verify whether IL-2 and RA decreased serum VEGF in NSCLC patients showing a clinical benefit from chemotherapy. The secondary end point was the evaluation of clinical outcome. We treated 38 patients with advanced NSCLC who had a complete or partial response or disease stability to chemotherapy and had a median serum VEGF level of 508 ng/mL; as maintenance therapy, they received subcutaneous IL-2 (1.8 x 10(6) IU) and oral RA. Matched controls (n = 87) were selected from a large cohort of patients with a similar disease status, including clinical benefit from chemotherapy. The most common adverse events were mild cutaneous skin rash and fever. Serum VEGF decreased to a mean level of 152 ng/mL (P = 0.0002). A statistically significant improvement in immune function was observed (lymphocyte and natural killer cell numbers and CD4+/CD8+ ratio) with respect to baseline values and controls. An improvement in the clinical outcome was also observed compared with controls. These data show that the administration of low-dose subcutaneous IL-2 and oral RA to patients with advanced NSCLC showing a clinical benefit from chemotherapy is feasible with a low-toxicity profile, decreases VEGF, and seems to improve progression-free and overall survival.

Abstract
PURPOSE In the present study, we investigated the prognostic value of vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP)-9 serum levels in patients with metastatic non-small cell lung cancer (NSCLC). PATIENTS AND METHODS From September 1999 to June 2001, pretreatment serum levels of VEGF and MMP-9 were analysed in 194 patients of a randomized phase III trial with enzyme-linked immunoassays. RESULTS Patients with a VEGF serum level higher than the median serum level (10,995 pg/ml) had a significantly shorter overall survival than those with a lower serum level (P=0.04). The MMP-9 serum level did not correlate with survival. In a multivariate Cox regression analysis, only the pretreatment serum level of VEGF, the Karnofsky performance status, and the presence of bone metastases were identified as independent prognostic factors. CONCLUSIONS The pretreatment VEGF serum level was identified as independent prognostic factor in this study and may help to assess individual risk and treatment profiles in patients with metastatic NSCLC.

Abstract
Angiogenesis is the formation of new blood vessels out of the existing vascular bed. Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) are potent circulating angiogenic factors, whereas cystatin C is one of the most important extracellular inhibitors of several cysteine proteinases. Because proteases degrade interstitial connective tissue and basement membranes during tumor growth and metastasis, an association between cystatin C and the angiogenic factors seems plausible. The primary aim of the present study was to investigate if such a correlation exists between these serum markers. The secondary aim was to determine the prognostic value of these circulating cytokines and cystatin C, collected prior to therapy, in patients with esophageal carcinoma.A total of 42 patients with esophageal carcinoma donated serum samples prior to therapy. VEGF and bFGF were correlated to platelet and leukocyte counts and VEGF was correlated to tumor volume (p = 0.04), whereas bFGF was not (p = 0.08). VEGF was significantly correlated with cystatin C (p = 0.027). Survival analysis showed that VEGF regarded as a continuous variable was associated with a significantly poorer survival in the univariate analysis (p = 0.023); however, this was not found for bFGF (p = 0.46). Neither of the angiogenic factors were associated with survival in the multivariate analysis. In the univariate analysis, cystatin c was correlated with survival (p = 0.01), but this was not found in the multivariate analysis (p = 0.28). In conclusion, VEGF was correlated with cystatin C, possible explanations being discussed in the present article. Results of the present study indicate that use of the angiogenic factors as prognostic factors, prior to therapy in patients with esophageal carcinoma, appears limited.

Abstract
OBJECTIVE To clarify the clinical significance of vascular endothelial growth factor (VEGF) in Japanese patients with small cell lung cancer (SCLC). MATERIALS AND METHODS We measured serum VEGF levels using an enzyme-linked immunosorbent assay in 45 patients with SCLC before treatment and in 38 patients with benign pulmonary disease and in 32 healthy subjects (71 non-malignant subjects). VEGF immunostaining was performed in tissue biopsies obtained from 23 SCLC patients during bronchoscopic examination. RESULTS Median serum VEGF level was 332 pg/ml in patients with SCLC and 160 pg/ml in non-malignant subjects, respectively. The 95% cut-off level to exclude non-malignant subjects was 500 pg/ml. An elevated VEGF level (>500 pg/ml) was found more frequently in patients with extensive disease of SCLC than in those with the limited disease (p<0.01). A significant positive correlation was found between the serum VEGF level and platelet count in SCLC patients (r=0.389; p=0.0083). Serum VEGF level also correlated with serum lactate dehydrogenase in SCLC patients (r=0.381; p=0.0098). However, it did not correlate with serum neuron-specific enolase and pro-gastrin-releasing peptide level. Patients with the elevated VEGF levels had significantly shorter progression-free time than those with the normal VEGF levels (p<0.05). Patients with the elevated VEGF levels had a significantly shorter overall survival time than those with the normal VEGF levels in univariate survival analysis (p<0.05). Further, the elevated VEGF level remained as a significant determinant of poor survival in multivariate analysis (p<0.01). Serum VEGF level was significantly higher in patients with positive VEGF protein immunoreactivity in tumor tissue in SCLC. CONCLUSION Elevated serum VEGF levels were associated with poor outcome in SCLC.

Abstract
Histological classification and staging are cornerstones of diagnosis in lung cancer. Treatment options have been enriched in the last few years by the development of a number of new drugs, and therapy is now increasingly being carried out within multimodal concepts and at earlier stages. Still, outcome of the disease is far from satisfactory and progress in clinical and preclinical research is time-consuming. With the whole variety of potent new therapeutic compounds including classical cytostatics and biological factors at hand, many now believe that a clear improvement of treatment results will be derived from a better understanding of the biology of these tumours and a resulting improvement of diagnosis. Biological factors reflecting the underlying tumour biology and aspects of clinically important pathomechanisms may not only better predict outcome of the disease but also of its treatment, serving as surrogate markers for a more appropriate general intensification of therapy and ideally for specific "targeted" interventions. This article describes the different insights in the biology of these tumours in relation with the representing surrogate markers, and opens routes to possible diagnostic and therapeutic consequences.

Abstract
Angiogenesis is believed to play a critical role in cancer; however, antiangiogenic therapy has not been demonstrated to improve the survival of patients who have lung cancer. In this article, the evidence that supports a role for angiogenesis in the pathogenesis of lung cancer, trials of antiangiogenic agents in lung cancer performed to date, and the lessons learned from these studies are discussed.

Abstract
BACKGROUND Angiogenesis, the formation of new blood vessels from the existing vascular bed, is essential step for the growth and invasion of the primary tumor. Vascular endothelial growth factor (VEGF) is known to play crucial role in tumor angiogenesis. Increased serum VEGF levels may be associated with poor prognosis in patients with non-small cell lung cancer (NSCLC). METHODOLOGY In the present study, we measured plasma VEGF levels in 20 normal subjects and 75 patients with untreated NSCLC; 23 operable (stages I, II, IIIA) and 52 inoperable (stages IIIB, IV) (Histology: squamous cell carcinoma, 40; adenocarcinoma, 27; undetermined, 8). VEGF was measured by enzyme-linked immunosorbent assay. RESULTS The median VEGF level in patient group was 119 pg/ml (29-1235), which was significantly higher than the control group (P = 0.044). Median survival of patients was 210 days (30-220). The patients were divided into high VEGF (> 119 pg/ml) and low VEGF (< 119 pg/ml) groups using the median value as a cut-off. It was investigated if there were significant associations between serum VEGF level and clinico-pathological parameters like age, sex, histopathological diagnosis and TNM staging. Also high VEGF and low VEGF patient groups were compared according to the median survival. CONCLUSIONS Serum VEGF level is significantly associated with the clinical staging of the patients (operable and inoperable) (P = 0.031) and it also correlates with the prognosis of the patients (P = 0.0006).

Abstract
Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) have both been implicated to have roles in tumour angiogenesis. In the present retrospective study, serum VEGF and bFGF from patients with locally advanced non-small cell lung cancer (NSCLC) were analysed before, during and after treatment. Seventy-three patients and a total of 460 serum samples were analysed for VEGF and 443 serum samples were analysed for bFGF. Pre-treatment bFGF levels in patients with normal platelet counts, were correlated to poorer survival, P-value = 0.047. During chemotherapy, each rise of one unit bFGF corresponded to a hazard ratio of 4.06 (P=0.022). In patients with normal platelet counts, VEGF levels after radiotherapy significantly correlated to good prognosis (P=0.023), during radiotherapy VEGF levels indicated the same correlation (P=0.085). We conclude that serum VEGF and especially bFGF are of clinical interest as prognostic factors, especially in patients presenting with normal platelet counts.
