Loeffler E, Ancel J, Dalstein V, Deslée G, Polette M, Nawrocki-Raby B. HER2 Alterations in Non-Small Cell Lung Cancer: Biologico-Clinical Consequences and Interest in Therapeutic Strategies. Life (Basel) 2023; 14:64. [PMID: 38255679 PMCID: PMC10820545 DOI: 10.3390/life14010064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 12/20/2023] [Accepted: 12/21/2023] [Indexed: 01/24/2024] Open
Abstract
Lung cancer stands as the first cause of death by cancer in the world. Despite the improvement in patients' outcomes in the past decades through the development of personalized medicine approaches, a substantial portion of patients remains ineligible for targeted therapies due to the lack of a "druggable" molecular target. HER2, a receptor tyrosine kinase member of the EGFR/ErbB family, is known to show oncogenic properties. In this review, we focus on the different HER2 dysregulation mechanisms that have been observed in non-small cell lung cancer (NSCLC): gene mutation, gene amplification, protein overexpression and protein hyper-phosphorylation, the latter suggesting that HER2 dysregulation can occur independently of any molecular aberration. These HER2 alterations inevitably have consequences on tumor biology. Here, we discuss how they are not only involved in abnormal proliferation and survival of cancer cells but also potentially in increased angiogenic properties, mesenchymal features and tumor immune escape. Finally, we review the impact of these HER2 alterations in various therapeutic approaches. While standard chemotherapy and groundbreaking immunotherapy seem rather ineffective for HER2-altered NSCLCs, the development of HER2-targeted therapies such as tyrosine kinase inhibitors, anti-HER2 antibodies and especially antibody-drug conjugates could provide new hopes for patients.

Abstract
In humans, even where millions of spermatozoa are deposited upon ejaculation in the vagina, only a few thousand enter the uterine tube (UT). Sperm transiently adhere to the epithelial cells lining the isthmus reservoir, and this interaction is essential in coordinating the availability of functional spermatozoa for fertilization. The binding of spermatozoa to the UT epithelium (mucosa) occurs due to interactions between cell-adhesion molecules on the cell surfaces of both the sperm and the epithelial cell. However, in humans, there is little information about the molecules involved. The aim of this study was to perform a histological characterization of the UT focused on determining the tissue distribution and deposition of some molecules associated with cell adhesion (F-spondin, galectin-9, osteopontin, integrin αV/β3) and UT's contractile activity (TNFα-R1, TNFα-R2) in the follicular and luteal phases. Our results showed the presence of galectin-9, F-spondin, osteopontin, integrin αV/β3, TNFα-R1, and TNFα-R2 in the epithelial cells in ampullar and isthmic segments during the menstrual cycle. Our results suggest that these molecules could form part of the sperm-UT interactions. Future studies will shed light on the specific role of each of the identified molecules.

Abstract
Bronchiolitis obliterans syndrome (BOS) is the most common form of CLAD and is characterized by airflow limitation and an obstructive spirometric pattern without high-resolution computed tomography (HRCT) evidence of parenchymal opacities. Computed tomography and microCT analysis show abundant small airway obstruction, starting from the fifth generation of airway branching and affecting up to 40-70% of airways. The pathogenesis of BOS remains unclear. It is a multifactorial syndrome that leads to pathological tissue changes and clinical manifestations. Because BOS is associated with the worst long-term survival in LTx patients, many studies are focused on the early identification of BOS. Markers may be useful for diagnosis and for understanding the molecular and immunological mechanisms involved in the onset of BOS. Diagnostic and predictive markers of BOS have also been investigated in various biological materials, such as blood, BAL, lung tissue and extracellular vesicles. The aim of this review was to evaluate the scientific literature on markers of BOS after lung transplant. We performed a systematic review to find all available data on potential prognostic and diagnostic markers of BOS.

Abstract
PURPOSE OF REVIEW In the current review, we will explore the molecular bases that have determined the design of clinical trials exploring the efficacy of antivascular agents in combination with chemotherapy, immune check point inhibitors and epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in patients with advanced nonsmall cell lung cancer. RECENT FINDINGS Recent clinical trials have demonstrated the synergistic effect of antivascular agents with immune checkpoint inhibitors and EGFR-TKIs, despite no molecular marker has been identified yet to select patients. SUMMARY Lung cancer remains one of the first causes of cancer-related death. However, thanks to the development of stratified molecular medicine and the introduction of immune checkpoint inhibitors, patients' survival has significantly improved. Due to the critical role of pro-angiogenic factors in cancer progression, antivascular agents targeting the vascular endothelial growth factor (VEGF) and its receptor (VEGFR) have been developed. Their efficacy has been explored in combination with chemotherapy, and immune checkpoint inhibitors, with promising but not definitive conclusions about their impact on prolonging patients' survival.

Abstract
Lung cancer is the leading cause of cancer-related deaths worldwide, in which angiogenesis is highly required for lung cancer cell growth and metastasis. Genetic regulation of this multistep process is being studied extensively, however, relatively less is known about the epigenetic regulation of angiogenesis in lung cancer. Several epigenetic alterations contribute to regulating angiogenesis, such as epimodifications of DNA, posttranslational modification of histones, and expression of noncoding RNAs. Here, we review the current knowledge of the epigenetic regulation of angiogenesis and discuss the potential clinical applications of epigenetic-based anticancer therapy in lung cancer. Overall, epigenetic-based therapy will likely emerge as a prominent approach to treat lung cancer in the future.

Abstract
The vascular endothelial growth factor (VEGF) family and its receptors play fundamental roles not only in physiological but also in pathological angiogenesis, characteristic of cancer progression. Aiming at finding putative treatments for several malignancies, various small molecules, antibodies, or protein-based drugs have been evaluated in vitro and in vivo as VEGF inhibitors, providing efficient agents approved for clinical use. Due to the high clinical importance of VEGF, also a great number of anti-VEGF nucleic acid-based aptamers-that is, oligonucleotides able to bind with high affinity and specificity a selected biological target-have been developed as promising agents in anticancer strategies. Notable research efforts have been made in optimization processes of the identified aptamers, searching for increased target affinity and/or bioactivity by exploring structural analogues of the lead compounds. This review is focused on recent studies devoted to the development of DNA-based aptamers designed to target VEGF. Their therapeutic potential as well as their significance in the construction of highly selective biosensors is here discussed.

Nucleic Acids Res 2019; 47:8318-8331.

Abstract
The G-quadruplex-forming VEGF-binding aptamer V7t1 was previously found to be highly polymorphic in a K+-containing solution and, to restrict its conformational preferences to a unique, well-defined form, modified nucleotides (LNA and/or UNA) were inserted in its sequence. We here report an in-depth biophysical characterization of V7t1 in a Na+-rich medium, mimicking the extracellular environment in which VEGF targeting should occur, carried out combining several techniques to analyse the conformational behaviour of the aptamer and its binding to the protein. Our results demonstrate that, in the presence of high Na+ concentrations, V7t1 behaves in a very different way if subjected or not to annealing procedures, as evidenced by native gel electrophoresis, size exclusion chromatography and dynamic light scattering analysis. Indeed, not-annealed V7t1 forms both monomeric and dimeric G-quadruplexes, while the annealed oligonucleotide is a monomeric species. Remarkably, only the dimeric aptamer efficiently binds VEGF, showing higher affinity for the protein compared to the monomeric species. These findings provide new precious information for the development of improved V7t1 analogues, allowing more efficient binding to the cancer-related protein and the design of effective biosensors or theranostic devices based on VEGF targeting.

Abstract
MicroRNAs (miRNAs) have been implicated in a wide range of biological processes including angiogenesis. MiR-204 was identified as a tumor suppressor in multiple cancer types, including lung adenocarcinoma. However, the function of miR-204 in lung tumor angiogenesis remains unknown. In this study, we found that the miR-204 expression was decreased in lung adenocarcinoma based on the cancer genome atlas (TCGA) analysis and gain-of-function experiment showed that miR-204 promoted cancer cell apoptosis and suppressed cell proliferation, migration in vitro and tumor growth in vivo. Functionally, both the tube formation and migration abilities of human umbilical vein endothelial cells (HUVECs) were suppressed by conditioned media from lung cancer A549 cells with miR-204 overexpression. Meanwhile, these conditioned media inhibited proliferation and promoted apoptosis in HUVECs. The key angiogenesis inducer hypoxia inducible factor-1α (HIF1α) and the pro-angiogenic mediators vascular endothelial growth factor and platelet-derived growth factor were decreased in A549 cells transfected with miR-204 mimics. Mechanistically, miR-204 could target Janus kinase 2 (JAK2) and further impaired signal transducer and activator of transcription 3 both in vitro and in vivo. Inhibition of JAK2 or signal transducer and activator of transcription 3 (STAT3) activity with small chemical inhibitors in A549 cells impaired lung adenocarcinoma angiogenesis in vitro. Meanwhile, conditional media from interleukin 6-treated lung normal epithelial cells significantly promoted tube formation of HUVEC, which was disturbed by miR-204 overexpression. Taken together, our findings demonstrate that miR-204 attenuates angiogenesis in lung adenocarcinoma potentially via JAK2-STAT3 pathway. Clinically, the miR-204/JAK2/STAT3 signaling pathway is a putative therapeutic target in lung adenocarcinoma. © 2017 IUBMB Life, 70(1):81-91, 2018.

Abstract
Prolonged low-grade inflammation or smoldering inflammation is a hallmark of cancer. Mast cells form a heterogeneous population of immune cells with differences in their ultra-structure, morphology, mediator content, and surface receptors. Mast cells are widely distributed throughout all tissues and are stromal components of the inflammatory microenvironment that modulates tumor initiation and development. Although canonically associated with allergic disorders, mast cells are a major source of pro-tumorigenic (e.g., angiogenic and lymphangiogenic factors) and antitumorigenic molecules (e.g., TNF-α and IL-9), depending on the milieu. In certain neoplasias (e.g., gastric, thyroid and Hodgkin's lymphoma) mast cells play a pro-tumorigenic role, in others (e.g., breast cancer) a protective role, whereas in yet others they are apparently innocent bystanders. These seemingly conflicting results suggest that the role of mast cells and their mediators could be cancer specific. The microlocalization (e.g., peritumoral vs intratumoral) of mast cells is another important aspect in the initiation/progression of solid and hematologic tumors. Increasing evidence in certain experimental models indicates that targeting mast cells and/or their mediators represent a potential therapeutic target in cancer. Thus, mast cells deserve focused consideration also as therapeutic targets in different types of tumors. There are many unanswered questions that should be addressed before we understand whether mast cells are an ally, adversary, or innocent bystanders in human cancers.

Abstract
Background Angiogenesis is a hallmark of cancer and plays a critical role in lung cancer progression, which involves interactions between cancer cells, endothelial cells and the surrounding microenvironment. However, the gene expression profiles and the changes in the biological phenotype of vascular endothelial cells after interactions with lung cancer cells remain unclear. Methods An indirect transwell co-culture system was used to survey the interaction between human umbilical vein endothelial cells (HUVECs) and human lung adenocarcinoma CL1-5 cells, as well as to investigate the morphological and molecular changes of HUVECs. The differentially expressed genes (DEGs) in HUVECs after co-culture with cancer cells were identified by microarray. Moreover, a publicly available microarray dataset of 293 non-small-cell lung cancer (NSCLC) patients was employed to evaluate the prognostic power of the gene signatures derived from HUVECs. Results The interaction between HUVECs and lung cancer cells changes the morphology of HUVECs, causing them to have a mesenchymal-like morphology and alter their cytoskeleton organization. Furthermore, after co-culture with lung cancer cells, HUVECs showed increased cell motility and microvessel tube formation ability and a decreased apoptotic percentage. Transcriptomic profiling of HUVECs revealed that many survival-, apoptosis- and angiogenesis-related genes were differentially expressed after interactions with lung cancer cells. Further investigations showed that the PI3K/Akt signalling pathway and COX-2 are involved in endothelial tube formation under the stimulation of lung cancer cells. Moreover, Rac-1 activation might promote endothelial cell motility through the increased formation of lamellipodia and filopodia. The inhibitors of PI3K and COX-2 could reverse the increased tube formation and induce the apoptosis of HUVECs. In addition, the gene signatures derived from the DEGs in HUVECs could predict overall survival and disease-free survival in NSCLC patients and serve as an independent prognostic factor. Conclusions In this study, we found that cancer cells can promote endothelial cell tube formation and survival, at least in part, through the PI3K/Akt signalling pathway and thus change the microenvironment to benefit tumour growth. The gene signatures from HUVECs are associated with the clinical outcome of NSCLC patients.

Xuan ZX, Zhang S, Yuan SJ, Wang W, Yu J. Prognostic value of angiopoietin-2 in non-small cell lung cancer patients: a meta-analysis. World J Surg Oncol 2016; 14:237. [PMID: 27589869 PMCID: PMC5010677 DOI: 10.1186/s12957-016-0992-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2016] [Accepted: 08/18/2016] [Indexed: 02/05/2023] Open
Abstract
Background Non-small cell lung cancer (NSCLC) is the most frequent cause of cancer deaths worldwide. The targeted therapy had made important progress in recent years, but few potential predictive biomarkers for prognosis of NSCLC patients were identified. Angiopoietin-2 (Ang-2), a cytokine upregulated in tumor endothelial cells and some tumor cells including NSCLC, is a partial agonist and antagonist of angiopoietin-1 (Ang-1). Ang-1 is another ligand for the tyrosine kinase receptor Tie2; it promotes recruitment of pericytes and smooth muscle cells, stabilizing vascular networks by binding to Tie2. Although many studies mainly considered that Ang-2 correlated with progression and prognosis of NSCLC significantly, there are much conflicting and controversial data. Therefore, we conducted a meta-analysis to assess the relationship between Ang-2 and prognosis, a clinical outcome of NSCLC. Methods The search was based on major databases from PubMed, Cochrane Library, EMBASE, and CNKI, and 20 eligible publications (range from 2002 to 2015) are included in our meta-analysis with 2011 NSCLC patients in total. These studies illuminated the correlation between the expression of Ang-2 and NSCLC, based on either prognostic factors or clinicopathological features. Pooled calculations were carried out on the odds ratio (OR) and the corresponding 95 % confidence interval (CI) to perform this meta-analysis, and all statistical analyses were carried out by STATA 12.0 and Review Manager 5.3. Results According to our results, the expression of Ang-2 in NSCLC tissues was significantly higher than that in normal lung tissues, indicating that Ang-2 over-expression may be a predictive marker (pooled OR = 5.09, corresponding 95 % confidence interval (95 % CI) 3.10–8.36, p = 0.000). In addition, our pooled data showed that Ang-2 expression was positively correlated with tumor stages (pooled OR = 3.58, 95 % CI 2.40–5.35, p = 0.000), differentiation (pooled OR = 0.65, 95 % CI 0.45–0.94, p = 0.02), lymphatic invasion (pooled OR = 3.15, 95 % CI 1.97–5.03, p = 0.000), and poor survival (pooled OR = 1.93, 95 % CI 1.47–2.52, p = 0.000) of NSCLC, but seems to have no significant impact on tumor size (pooled OR = 1.09, 95 % CI 0.59–2.00, p = 0.78). Conclusions These results demonstrate that Ang-2 expression significantly correlated with poor prognosis for patients with NSCLC.

Abstract
Osteopontin (OPN) plays an important role in the progression and metastasis of cancer. However, the role of OPN as a prognostic factor in non-small-cell lung cancer (NSCLC) remains controversial. The aim of this study was to investigate the association between OPN expression and prognosis in patients with NSCLC using a meta-analysis. Based on PubMed, Ovid Medline, Embase, ISI, ScienceDirect and SpringerLink databases, related articles published prior to January, 2013 were collected. A meta-analysis was conducted to investigate the association of OPN expression with overall survival (OS) and progression-free survival (PFS) in patients with NSCLC. Hazard ratio (HR) with 95% confidence interval (CI) was used to assess the strength of this association. A total of 6 studies, including 776 patients, were found to be eligible for the meta-analysis. No heterogeneity was observed in OS or PFS, whereas low OPN expression was found to be correlated with better OS (HR=0.57, 95% CI: 0.46-0.70) and PFS (HR=0.62, 95% CI: 0.49-0.77). This meta-analysis demonstrated an association of OPN with poor prognosis in NSCLC patients. However, prospective studies are required to confirm these findings.

Abstract
Decorin, a member of the small leucine-rich proteoglycans family, exists and plays multifunctional roles in stromal and epithelial cells. Emerging evidences showed that decorin is dysregulated expression in a wide variety of human tumors and affects a broad biology process of cancer cells, including growth, metastasis, and angiogenesis. Recent studies demonstrated that decorin could affect A549 proliferation though decreasing TGF-β1, cycling D1 expression and increasing P53 and P21 expression. However, limited data are available on the effect of decorin on metastasis of non-small-cell lung cancer (NSCLC) cell lines and how decorin impacts metastasis is still unknown. In this study, we identified decorin mRNA expression through Oncomine database and verified the expression of decorin mRNA and protein in 50 patients who underwent primary surgical resection of a NSCLC in the Department of Thoracic Surgery, Jinling Hospital, Nanjing University School of Medicine, China, between September 2013 and March 2014 by quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) and Western blot. Also, the correlationship between decorin and the NSCLC patients' clinical characteristics or survival ( www.kmplot.com ) was analyzed. Via ectopic expression analyses and Western blot, the roles of decorin in proliferation, metastasis, and the underline mechanism for decorin expression were further explored. We found that decorin was downregulated in NSCLC tissues compared with the adjacent normal lung tissues or normal tissues. Additionally, the expression of decorin was correlated with tumor size, lymph node metastasis, tumor stage, and prognosis. We also showed that overexpression of decorin could inhibit NSCLC cell lines proliferation and metastasis. Through Western blot analysis, we identified that E-cadherin and vascular endothelial growth factor (VEGF) are two key factors responsible for the growth arrest and metastasis inhibition induced by decorin in NSCLC. Our results indicated that decorin plays crucial roles in NSCLC against carcinogenesis and progression. Decorin might be a predictive factor and an attractive therapeutic target for NSCLC patients.

Abstract
Background Pathological angiogenesis plays an essential role in tumor aggressiveness and leads to unfavorable prognosis. The aim of this study is to detect the potential role of Retinoblastoma binding protein 2 (RBP2) in the tumor angiogenesis of non-small cell lung cancer (NSCLC). Methods Immunohistochemical staining was used to detect the expression of RBP2, hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF) and CD34. Two pairs of siRNA sequences and pcDNA3-HA-RBP2 were used to down-regulate and up-regulate RBP2 expression in H1975 and SK-MES-1 cells. An endothelial cell tube formation assay, VEGF enzyme-linked immunosorbent assay, real-time PCR and western blotting were performed to detect the potential mechanisms mediated by RBP2 in tumor angiogenesis. Results Of the 102 stage I NSCLC specimens analyzed, high RBP2 protein expression is closely associated with tumor size (P = 0.030), high HIF-1α expression (P = 0.028), high VEGF expression (P = 0.048), increased tumor angiogenesis (P = 0.033) and poor prognosis (P = 0.037); high MVD was associated with high HIF-1α expression (P = 0.034), high VEGF expression (P = 0.001) and poor prognosis (P = 0.040). Multivariate analysis indicated that RBP2 had an independent influence on the survival of patients with stage I NSCLC (P = 0.044). By modulating the expression of RBP2, our findings suggested that RBP2 protein depletion decreased HUVECs tube formation by down-regulating VEGF in a conditioned medium. RBP2 stimulated the up-regulation of VEGF, which was dependent on HIF-1α, and activated the HIF-1α via phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway. Moreover, VEGF increased the activation of Akt regulated by RBP2. Conclusions The RBP2 protein may stimulate HIF-1α expression via the activation of the PI3K/Akt signaling pathway under normoxia and then stimulate VEGF expression. These findings indicate that RBP2 may play a critical role in tumor angiogenesis and serve as an attractive therapeutic target against tumor aggressiveness for early-stage NSCLC patients.

Abstract
Osteopontin (OPN) is a glycoprotein involved in invasion, progression and metastasis of many carcinomas. It contains several functional domains including binding sites for αv integrins, cell surface molecules playing a major role in mediating cell migration and adhesion. The aim of the study was to evaluate the expression of osteopontin in human non-small cell lung cancer (NSCLC) and to determine its possible prognostic significance as well as relation to apoptosis and αv integrin expression. We analyzed 111 surgically resected NSCLC for immunohistochemical expression of OPN and αv integrin. OPN expression was compared to apoptotic rate and clinicopathological parameters such as tumor size, histological grade, lymph node status, pT, and TNM stage. Apoptotic rate was measured by TUNEL staining method. OPN expression in NSCLC was significantly higher in lung adenocarcinomas (AC) then in squamous cell carcinomas (p<0.001). There was no correlation between OPN expression and clinicopathological parameters. The level of OPN expression in AC was associated with decreased apoptotic activity of tumor cells (p=0.006), and correlated with αv integrin expression (p=0.048), particularly in low stage tumors (p=0.013). Prolonged tumor cell survival in lung AC due to OPN and αv integrin overexpression may have an impact on tumor progression and resistance to therapy.

Abstract
BACKGROUND The vascular endothelial growth factor (VEGF) mediates vasculogenesis and angiogenesis through promoting endothelial cell growth, migration and mitosis, and has involvement in cancer pathogenesis, progression and metastasis. However, the prognostic value of VEGF in patients with prostate cancer remains controversial. OBJECTIVES The aim of our study was to evaluate the prognostic value of VEGF in prostate cancer, and summarise the results of related research on VEGF. METHODS In accordance with an established search strategy, 11 studies with 1,529 patients were included in our meta-analysis. The correlation of VEGF-expression with overall survival and progression-free survival was evaluated by hazard ratio, either given or calculated. RESULTS The studies were categorized by introduction of the author, demographic data in each study, prostate cancer-relatived information, VEGF cut-off value, VEGF subtype, methods of hazard ratio (HR) estimation and its 95% confidence interval (CI). High VEGF-expression in prostate cancer is a poor prognostic factor with statistical significance for OS (HR=2.32, 95%CI: 1.40-3.24). However, high VEGF-expression showed no effect on poor PFS (HR=1.30, 95%CI: 0.88-1.72). Using Begg's, Egger's test and funnel plots, we confirmed lack of publication bias in our analysis. CONCLUSION VEGF might be regarded as a prognostic maker for prostate cancer, as supported by our meta-analysis. To achieve a more definitive conclusion enabling the clinical use of VEGF in prostate cancer, we need more high-quality interventional original studies following agreed research approaches or standards.

Abstract
Metastasis-associated protein 1 (MTA1) high expression has been detected in a wide variety of human aggressive tumors and plays important roles in the malignant biological behaviors such as invasion, metastasis, and angiogenesis. However, the specific roles and mechanisms of MTA1 protein in regulating the malignant behaviors of non-small-cell lung cancer (NSCLC) cells still remain unclear. To elucidate the detailed functions of MTA1 protein, we down-regulated the MTA1 protein expression in NSCLC cell line by RNA interference (RNAi) in vitro, and found that down-regulation of MTA1 protein significantly inhibited the migration and invasion potentials of 95D cells. Further research revealed that down-regulation of MTA1 protein significantly decreased the activity of matrix metalloproteinase-9, which could be the mechanism responsible for the inhibition of 95D cells migration and invasion. In addition, the tube formation assay demonstrated that the number of complete tubes induced by the conditioned medium of MTA1-siRNA 95D cells was significantly smaller than that of 95D cells. These findings demonstrate that MTA1 protein plays important roles in regulating the migration, invasion, and angiogenesis potentials of 95D cells, suggesting that MTA1 protein down-regulation by RNAi might be a novel therapeutic approach to inhibit the progression of NSCLC.

Abstract
Human papillomavirus (HPV) infection is associated with non-smoking female lung cancer. Our previous report demonstrated that HPV 16 promotes lung tumor cell progression by up-regulating interleukin-17 (IL-17). IL-17 and its downstream signaling mediator, interleukin-8 (IL-8), have been implicated to modulate a variety of pro-angiogenic factors and play important roles in tumor angiogenesis and metastasis. Accordingly, we hypothesized that HPV infection may potentiate tumorigenic and metastatic characteristics of the infected cells through IL-8. The goal of the present study was to determine whether HPV infection in lung adenocarcinoma cells can promote the expression of IL-8 and metalloproteinases (MMPs) to make the transformed cells equipped with angiogenic and metastatic characteristics. The expression of IL-8 and MMPs in HPV 16 E6-transfected H1299 cells was analyzed to examine the hypothesis. HPV 16 E6 up-regulates pro-angiogenic MMP-2 and MMP-9 through inducing IL-8 expression in lung cancer cells. The results indicate that, in addition to cell proliferation-related machinery, HPV infection promotes the expression and activities of angiogenic and metastatic molecules in lung adenocarcinoma cells. The cytokines induced by HPV infection may work together to confer the malignant and tumorigenic potentials on the infected cells by promoting machineries of growth, angiogenic and metastatic characteristics.

Abstract
We propose a computational simulation framework for describing cancer-therapeutic transport in the lung. A discrete vascular graph model (VGM) is coupled to a double-continuum model (DCM) to determine the amount of administered therapeutic agent that will reach the cancer cells. An alveolar cell carcinoma is considered. The processes in the bigger blood vessels (arteries, arterioles, venules and veins) are described by the VGM. The processes in the alveolar capillaries and the surrounding tissue are represented by a continuum approach for porous media. The system of equations of the coupled discrete/continuum model contains terms that account for degradation processes of the therapeutic agent, the reduction of the number of drug molecules by the lymphatic system and the interaction of the drug with the tissue cells. The functionality of the coupled discrete/continuum model is demonstrated in example simulations using simplified pulmonary vascular networks, which are designed to show-off the capabilities of the model rather than being physiologically accurate.

Abstract
BACKGROUND The aims of this work are to detect the expression levels of metastasis-associated protein 1 (MTA1) in patients with early-stage non-small cell lung cancer (NSCLC), and to investigate the relationship of MTA1 protein with clinicopathologic factors, tumor angiogenesis, and prognosis. METHODS One hundred and two patients with pathologic stage I NSCLC who successfully underwent curative surgical resection were enrolled in this study. Immunohistochemical staining for MTA1 and CD34 was performed using the streptavidin-peroxidase method, and intratumoral microvessel density (MVD) was recorded by counting CD34-positive immunostained endothelial cells. All statistical analyses were performed with SPSS statistical software to determine the effects of MTA1 protein on clinicopathologic factors, tumor angiogenesis, and prognosis. RESULTS MTA1 protein overexpression was detected in 41 cases and was significantly associated with MVD (P = 0.008). MTA1 protein overexpression and high MVD were significantly associated with tumor relapse (P = 0.004 and 0.007) and poor 5-year disease-free survival (P = 0.001 and 0.004). Patients with MTA1 protein overexpression and high MVD had significantly poor overall survival (P = 0.005 and 0.043) and disease-specific survival (P = 0.006 and 0.031) at 5 years after operation. Multivariate analysis demonstrated that MTA1 protein overexpression was an independent prognosticator for unfavorable disease-free, overall, and disease-specific survival (P = 0.011, 0.024, and 0.046). CONCLUSIONS MTA1 protein overexpression is common in early-stage NSCLC and is significantly associated with tumor angiogenesis and poor survival. These findings suggest that MTA1 may have clinical potential as a promising predictor to identify individuals with poor prognostic potential and as a possible novel target molecule of antiangiogenic therapy for patients with early-stage NSCLC.

Abstract
Topiramate has been used in patients with brain tumors who develop epilepsy. In our previous research we found topiramate could inhibit tumor metastases of Lewis lung carcinoma in C57BL/6 mice. In this study we aimed to assess the antimetastatic activity of topiramate and determine its mechanism of action. After confirming the effects of topiramate on Lewis lung carcinoma in C57BL/6 mice, we assessed the mRNA expression of carbonic anhydrases II and IX, and the vascular endothelial growth factor (VEGF) distribution in tumor tissue. We studied the role of topiramate on primary angiogenesis using a chicken embryo chorioallantoic membrane angiogenesis model, and analyzed the protein profile of serum from mice treated with or without topiramate by two-dimensional electrophoresis. We found that topiramate significantly reduced the primary tumor growth (P<0.05) and the degree of damage to the lung alveoli caused by metastatic tumor deposits. The two-dimensional electrophoresis revealed changes that occurred with topiramate treatment and four down-regulated protein spots were clearly identified as tropomyosin, osteopontin, transthyretin, and serum amyloid A-1. The mRNA and protein expression of serum amyloid A-1, osteopontin and its receptor, integrin α(v)β(3) in tumor tissue were reconfirmed. The results suggest that topiramate has antitumor and antimetastatic effects on Lewis lung carcinoma. Its mechanism of action may be related to its inhibition of angiogenesis by down-regulation of osteopontin, VEGF and carbonic anhydrase II.

Abstract
Vascular endothelial growth factor A (VEGF-A) is a well-characterized regulator of physiological and pathological angiogenesis. Multiple therapeutic compounds interfering with VEGF-A-regulated signal transduction pathways are currently being developed for the treatment of neoplasias and other malignancies associated with pathological angiogenesis. A major challenge in developing anti-VEGF therapies are tumor intrinsic refractoriness and the emergence of treatment-induced resistance. A variety of molecular and cellular mechanisms contribute to tumor angiogenesis, including the recruitment of bone marrow (BM)-derived endothelial cell progenitors (EPCs) and inflammatory cells to the tumor mass. Among the latter, two types of tumor infiltrating, inflammatory cells were recently identified to mediate refractoriness to anti-VEGF treatment: CD11b + Gr1+ myeloid derived suppressor cells (MDSC) and tumor-associated macrophages (TAMs). In this chapter, we review some of the inflammatory components regulating tumor angiogenesis and their roles in mediating refractoriness toward anti-VEGF treatment. In addition, we discuss potential therapeutic strategies targeting angiogenic pathways regulated by inflammatory cells. A better understanding of the biological and molecular events involved in mediating refractoriness to anti-VEGF treatment may help to further improve therapeutic strategies targeting tumor angiogenesis.

Abstract
Angiogenesis is a key step in tumor growth and metastasis. The mechanism by which osteopontin (OPN) induces the angiogenesis of endothelial cells remains unclear. Here, we show that OPN confers cytoprotection through the activation of the PI3K/Akt pathway with subsequent upregulation of Bcl-xL and activation of nuclear factor-kappaB. OPN enhances the expression of vascular endothelial growth factor (VEGF) through the phosphorylation of AKT and extracellular signal-regulated kinase (ERK). In turn, OPN-induced VEGF activates PI3K/AKT and the ERK1/2 pathway as a positive feedback signal. Blocking the feedback signal by anti-VEGF antibody, PI3-kinase inhibitor or ERK inhibitor can partially inhibit the OPN-induced human umbilical vein endothelial cell (HUVEC) motility, proliferation and tube formation, while blocking the signal by anti-OPN or anti-alphavbeta3 antibody completely abrogates the biological effects of OPN on HUVECs. In addition, blood vessel formation is also investigated in vivo. The antiangiogenesis efficacy of anti-OPN antibody in vivo is more effective than that of anti-VEGF antibody, which only blocks the feedback signals. These data show that OPN enhances angiogenesis directly through PI3K/AKT- and ERK-mediated pathways with VEGF acting as a positive feedback signal. The results suggest that OPN might be a valuable target for developing novel antiangiogenesis therapy for treatment of cancer.

Abstract
PURPOSE S0003 was a phase III trial of carboplatin/paclitaxel with or without the hypoxic cytotoxin tirapazamine in patients with advanced or metastatic non-small-cell lung cancer (NSCLC). We investigated the relationship between clinical outcomes and plasma levels of the hypoxia-associated protein osteopontin (OPN) in patients on this protocol. PATIENTS AND METHODS Baseline plasma was obtained from 172 patients. In 56 patients, sequential plasma was obtained after one or two cycles. Concentrations of OPN, as well as plasminogen activator inhibitor-1 (PAI-1) and vascular endothelial growth factor (VEGF), were measured using enzyme-linked immunosorbent assay. Tumor expression of OPN was assessed by immunohistochemistry in 61 matched archival specimens. RESULTS Patients with lower OPN levels (below the median) had a significantly superior overall survival compared with patients with higher levels, regardless of treatment arm (hazard ratio [HR] = 0.60, P = .002). A similar correlation was observed for progression-free survival (HR = 0.69, P = .02). When examined as a continuous variable, OPN maintained its significant association with both progression-free (HR = 1.05, P = .01) and overall survival (HR = 1.09, P < .0001). Patients with lower plasma OPN levels were significantly more likely to have tumor response (P = .03). No differences were observed between treatment arms. Tumor OPN levels did not correlate with patient outcomes or with plasma levels. No associations were observed between patient outcomes and VEGF or PAI-1 levels; however, plasma concentrations of these markers were significantly interrelated (P < .0001) and significantly decreased after treatment (P = .0002 and P = .03, respectively). CONCLUSION Pretreatment plasma levels of OPN are significantly associated with patient response, progression-free survival, and overall survival in chemotherapy-treated patients with advanced NSCLC.

Abstract
Malignant pleural effusion (MPE) is associated with advanced-stage lung cancer and is a poor prognostic sign for these patients. Osteopontin (OPN) is a multifunctional cytokine that is involved in the tumor progression and angiogenesis of lung cancer cells. The purpose of this study is to investigate and provide evidence for the role of OPN in the formation of MPE associated with lung cancer. In this study, we established an OPN knockdown murine lung cancer cell line, 3LL cells, utilizing the small interfering RNA (siRNA) technique. To reveal the effect of OPN on the formation of MPE associated with lung cancer, we directly injected OPN knockdown 3LL cells, 3LL/OPN siRNA, or control cells, 3LL/control siRNA, into the pleural space of C57BL/6 mice. OPN knockdown significantly reduced the formation of MPE, but did not inhibit in vivo tumor growth of 3LL cells in mice. Vascular endothelial growth factor (VEGF) concentration in MPE was markedly decreased in the 3LL/OPN siRNA in comparison with that of the 3LL/control siRNA. In vitro, recombinant OPN protein enhanced VEGF secretion from human umbilical vein endothelial cell (HUVEC) or human mesothelial cell line, Met5A cells, in a concentration-dependent manner. These results suggest that OPN is positively involved in the formation of MPE of lung cancer presumably by promoting VEGF secretion from vascular endothelial cells or mesothelial cells. OPN could be an effective target molecule for reducing MPE in lung cancer patients.

Abstract
Osteopontin (OPN) is a multifunctional cytokine involved in cell signaling by interacting with alphavbeta3 integrins. Recent clinical studies have indicated that OPN expression is associated with tumor progression and poor prognosis among patients with lung cancer. However, the biological role of OPN in human lung cancer has not yet been well-defined. The purpose of this study is to investigate and provide evidence for the causal role of OPN regarding tumor growth and angiogenesis in human lung cancer. In this study, we developed a stable OPN transfectant from human lung cancer cell line SBC-3 which does not express the intrinsic OPN mRNA. To reveal the in vivo effect of OPN on tumor growth of human lung cancer, we subcutaneously injected OPN-overexpressing SBC-3 cells (SBC-3/OPN) and control cells (SBC-3/NEO) into the nude mice. Transfection with the OPN gene significantly increased in vivo tumor growth and neovascularization of SBC-3 cells in mice. These in vivo effects of OPN were markedly suppressed with administration of anti-alphavbeta3 integrin monoclonal antibody or anti-angiogenic agent, TNP-470. Furthermore, recombinant OPN protein enhanced human umbilical vein endothelial cell (HUVEC) proliferation in vitro, and this enhancement was significantly inhibited with the addition of anti-alphavbeta3 integrin antibody. Taken together, these results suggest that OPN plays a crucial role for tumor growth and angiogenesis of human lung cancer cells in vivo by interacting with alphavbeta3 integrin. Targeting the interaction between OPN and alphavbeta3 integrin could be effective for future development of anti-angiogenic therapeutic agents for patients with lung cancer.

Abstract
BACKGROUND Angiogenesis is a potential prognostic factor that has been investigated in patients with non-small-cell lung carcinoma. However, published studies of the role of angiogenesis as a prognostic factor are inconclusive. We aimed to collect individual patient data to assess microvessel-density counts (ie, a measure of angiogenesis) as a prognostic factor in non-small-cell lung carcinoma. METHODS We obtained published and unpublished datasets and extracted appropriate data, taking particular care to ensure data quality. Detailed information was obtained for the laboratory methods used by every research centre that generated the data. The outcome of interest was overall survival. We did a meta-analysis to estimate the prognostic role of microvessel density by combining separately estimated hazard ratios (HR) from every study, which were adjusted for tumour stage and age. Analyses were done separately for studies that used the Chalkley method or for those that counted all microvessels. FINDINGS 17 centres provided data for 3200 patients, 2719 of which were included in the analysis. All but three centres (datasets 9, 10, and 13-367 cases) had already published their findings, and six had updated follow-up information (datasets 1, 2, 3, 6, 7, and 8-1273 cases). For all but three centres (datasets 4, 11, and 13) some data corrections were necessary. For microvessel density counts obtained by the Chalkley method, the HR for death per extra microvessel was 1.05 (95% CI 1.01-1.09, p=0.03) when analysed as a continuous variable. For microvessel density counts obtained by the all vessels method, the HR for death per ten extra microvessels was 1.03 (0.97-1.09, p=0.3) when analysed as a continuous variable. INTERPRETATION Microvessel density does not seem to be a prognostic factor in patients with non-metastatic surgically treated non-small-cell lung carcinoma. This conclusion contradicts the results of a meta-analysis of published data only. Therefore, the methodology used to assess prognostic factors should be assessed carefully.

Abstract
Little is known about how the composition of stromal cells within the lung cancer microenvironment varies during tumor progression. We examined by immunohistochemistry each of six different stromal cell populations during the development of chemically induced primary lung cancer in mice. Blood vessels were seen even in microscopic lesions, and their numbers increased with tumor size. Neutrophils infiltrated the alveoli of tumor-bearing lungs and within the periphery of macroscopic adenomas and adenocarcinomas. The numbers of peritumoral lymphocytes and macrophages increased during oncogeny, but quantitative changes in mast cells and fibroblasts were not evident. Because macrophage depletion reduces tumor growth and these cells are thus important to tumorigenesis, we also investigated their phenotype. Pulmonary macrophages expressed arginase I (subtype M2) but not inducible nitric-oxide synthase in lungs with premalignant lesions, whereas macrophages in carcinoma-bearing lungs expressed inducible nitric-oxide synthase (subtype M1) but not arginase I. Local pulmonary stimuli did not seem responsible for this shift in macrophage activation state because monocytes still residing within the bone marrow adopted these expression patterns before entering the circulation, presumably in response to tumor-derived signals. These biochemical markers of macrophage activation states would have diagnostic and/or therapeutic value if analogous systemic shifts occur in humans.

Abstract
PURPOSE We have previously demonstrated in a pilot study of 348 invasive breast cancers that mast cell (MC) infiltrates within primary breast cancers are associated with a good prognosis. Our aim was to verify this finding in a larger cohort of invasive breast cancer patients and examine the relationship between the presence of MCs and other clinical and pathological features. EXPERIMENTAL DESIGN Clinically annotated tissue microarrays (TMAs) containing 4,444 cases were constructed and stained with c-Kit (CD-117) using standard immunoperoxidase techniques to identify and quantify MCs. For statistical analysis, we applied a split-sample validation technique. Breast cancer specific survival was analyzed by Kaplan-Meier [KM] method and log rank test was used to compare survival curves. RESULTS Survival analysis by KM method showed that the presence of stromal MCs was a favourable prognostic factor in the training set (P = 0.001), and the validation set group (P = 0.006). X-tile plot generated to define the optimal number of MCs showed that the presence of any number of stromal MCs predicted good prognosis. Multivariate analysis showed that the MC effect in the training set (Hazard ratio [HR] = 0.804, 95% Confidence interval [CI], 0.653-0.991, P = 0.041) and validation set analysis (HR = 0.846, 95% CI, 0.683-1.049, P = 0.128) was independent of age, tumor grade, tumor size, lymph node, ER and Her2 status. CONCLUSIONS This study concludes that stromal MC infiltration in invasive breast cancer is an independent good prognostic marker and reiterates the critical role of local inflammatory responses in breast cancer progression.

Abstract
Optical spectroscopy may be used for in vivo, noninvasive distinction of malignant from normal tissue. The aim of our study was to analyze the accuracy of various optical spectroscopic techniques for the classification of cancerous lesions of the bronchial tree. We developed a fiberoptic instrument allowing the measurement of autofluorescence spectroscopy (AFS), diffuse reflectance spectroscopy (DRS), and differential path length spectroscopy (DPS) during bronchoscopy. Spectroscopic measurements were obtained from 191 different endobronchial lesions (63 malignant and 128 nonmalignant) in 107 patients. AFS, DRS, and DPS sensitivity/specificity for the distinction between malignant and nonmalignant bronchial lesions were 73%/82%, 86%/81%, and 81%/88%, respectively. All three optical spectroscopic modalities facilitate an increase of the positive predictive value of autofluorescence bronchoscopy for the detection of endobronchial tumors. Even better results were obtained when the three spectroscopic techniques were combined.

Abstract
BACKGROUND Vascular endothelial growth factor-C (VEGF-C) plays an important role in lymphangiogenesis and activates VEGF receptor-3 (VEGFR-3). Lymphatic spread is an important prognostic factor in patients with lung adenocarcinoma. The aim of the current study was to determine whether the expression of VEGF-C and VEGFR-3 correlates with clinicopathologic factors and prognosis in patients with TNM classification T1 lung adenocarcinoma. METHODS The authors conducted a retrospective review of 129 consecutive patients who underwent complete resection for T1 lung adenocarcinoma. Immunohistochemical staining for VEGF-C, VEGF, VEGFR-3, CD34 (microvessels), tryptase (mast cells), and CD68 (macrophages) was performed to statistically analyze clinicopathologic implications of VEGF-C and VEGFR-3 status. RESULTS Of 129 patients with T1 lung adenocarcinoma, 56 (43.3%) patients were positive for tumor-cell VEGF-C and 73 (56.6%) and 69 (53.5%) patients were positive for tumor-cell and endothelial-cell VEGFR-3, respectively. Patients with positive staining for tumor-cell VEGF-C showed significantly less favorable survival rates than patients with negative staining (P = 0.031). The survival rates of patients with positive staining for tumor-cell and endothelial-cell VEGFR-3 were significantly lower than those with negative staining (P = 0.0034 and P = 0.0020, respectively). Patients with positive staining for both tumor-cell VEGF-C and endothelial-cell VEGFR-3 exhibited the most unfavorable prognoses. Multivariate analysis demonstrated that coexpression of tumor-cell VEGF-C and endothelial-cell VEGFR-3 was an independent negative prognostic factor (P = 0.0129) as well as N factor (P = 0.0020). CONCLUSIONS VEGF-C and VEGFR-3 status may be indicative of survival rates for patients with T1 lung adenocarcinoma.

Abstract
Human CCL23 (also known as CKbeta8, MPIF-1, or MIP-3) has been recently reported to induce endothelial cell migration and tube formation via CCR1. Matrix metalloproteinases (MMPs) are involved in the degradation of the extracellular matrix and also appear to play critical roles in angiogenesis. In the present study, we have demonstrated that CCL23 enhances the expression of MMP-2 mRNA and protein levels in endothelial cells in a dose-dependent manner, but has no effect on the expression levels of MMP-9, TIMP-1, TIMP-2, and MT1-MMP. CCL23 was shown to dose-dependently activate the expression of the MMP-2/Luc reporter gene, thereby indicating that it stimulates the transcription of the MMP-2 gene. Vascular endothelial cells, when exposed to CCL23, showed a marked ability to invade through a 3D Matrigel. This increase in invasion was also correlated with enhancements in the expression and activity of MMP-2. Neutralization with anti-CCL23 and anti-CCR1 antibodies, as well as the heat-induced inactivation of CCL23, resulted in a blockage of the CCL23-activated invasion, indicating that the invasion of HUVECs was induced by CCL23 specifically. Furthermore, we showed that the CCL23-induced invasion was inhibited by MMP inhibitors such as GM6001 and a specific MMP-2 Inhibitor I. Our results indicate that CCL23 may play a direct role in angiogenesis, via the upregulation of MMP-2 expression.

Abstract
In lung carcinomas the blood supply varies depending on tumor type and stage and can develop from pulmonary or bronchial circulation, or both. To examine this in vivo, primary bronchogenic Lewis lung carcinoma cells were intratracheally instilled in C57BL/6 mice. Within 7 days, histological examinations showed progressive tumor growth at the peripheral parenchymal region. The relative contribution of tumor blood supply via the pulmonary and systemic arteries was studied in detail using fluorescent microspheres (10 microm). When compared to healthy lung parenchyma (13:1), Lewis lung carcinoma tumor tissue (52:1) showed a fourfold increase in pulmonary to systemic microspheres, indicating that the pulmonary arteries are the predominant tumor-feeding vessels. After filling the vessels with a vascular cast, the microanatomy of vessels being derived from the pulmonary artery was visualized with micro computed tomography. Flat-panel volumetric computed tomography provided longitudinal visualization of tissue bridges between the growing tumor and the pulmonary vasculature. In this model of peripheral parenchymal malignancy, new imaging techniques allowed effective visualization of lung tumor growth and vascularization in living mice, demonstrating a pulmonary blood supply for lung tumors.

Abstract
Background Male breast cancer is a rare but aggressive and devastating disease. This disease presents at a later stage and in a more advanced fashion than its female counterpart. The immunophenotype also appears to be distinct when compared to female breast cancer. Angiogenesis plays a permissive role in the development of a solid tumor and provides an avenue for nutrient exchange and waste removal. Recent scrutiny of angiogenesis in female breast cancer has shown it to be of significant prognostic value. It was hypothesized that this holds true in invasive ductal carcinoma of the male breast. In the context of male breast cancer, we investigated the relationship of survival and other clinico-pathological variables to the microvascular density of the tumor tissue. Methods Seventy-five cases of primary male breast cancer were identified using the records of the Saskatchewan Cancer Agency over a period of 26 years. Forty-seven cases of invasive ductal carcinoma of the male breast had formalin-fixed paraffin-embedded tissue blocks that were suitable for this study. All cases were reviewed. Immunohistochemical staining was performed for the angiogenic markers (cluster designations 31 (CD31), 34 (CD34) and 105 (CD105), von Willebrand factor (VWF), and vascular endothelial growth factor (VEGF)). Microvascular density (MVD) was determined using average, centre, and highest microvessel counts (AMC, CMC, and HMC, respectively). Statistical analyses compared differences in the distribution of survival times and times to relapse between levels of MVD, tumor size, node status and age at diagnosis. In addition, MVD values were compared within each marker, between each marker, and were also compared to clinico-pathological data. Results Advanced age and tumor size were related to shorter survival times. There were no statistically significant differences in distributions of survival times and times to relapse between levels of MVD variables. There was no significant difference in MVD between levels of the different clinico-pathological variables. MVD was strongly and significantly correlated between AMC, CMC and HMC for CD31, CD34, and CD105 (p < 0.01) and remained moderate to weak for VWF and VEGF. Conclusion Microvascular density does not appear to be an independent prognostic factor in male breast cancer. However, the likelihood of death for men with breast cancer is increased in the presence of increased age at diagnosis and advanced tumor size. This is perhaps linked to inherent tumor vasculature, which is strongly related throughout a tumor section.

Abstract
RATIONALE Tumor hypoxia has both prognostic and therapeutic consequences for solid tumors. We developed a novel noninvasive technique, differential path-length spectroscopy (DPS), which allows the measurement of hypoxia-related parameters in the superficial microvasculature of tissue. OBJECTIVES The aim of this study was to measure the microvascular oxygenation of histologically normal endobronchial mucosa and of neoplastic lesions during bronchoscopy using DPS. METHODS Sixty-four patients with known or suspected malignancies of the lung were studied. One hundred and five endobronchial lesions (38 histologically normal, 37 metaplastic/mild dysplastic lesions, and 30 invasive carcinomas) were detected by white and/or autofluorescence bronchoscopy and measured using DPS. RESULTS We observed that bronchial tumors are characterized by a lower blood oxygen saturation and a higher blood content than normal mucosa. No differences were observed between normal and metaplastic/mild dysplastic mucosa. CONCLUSION DPS is a new optical technique allowing the noninvasive study of endobronchial tumor hypoxia.

Abstract
Two processes are necessary for a tumor colony to grow and become invasive: angiogenesis and basement membrane degradation. Angiogenesis is the formation of new blood vessels from the endothelium of existing vasculature, in response to the metabolic demand of the tumor. Assessment of the degree of tumor angiogenesis may improve risk stratification in patients with lung cancer, especially those with early-stage disease. In addition, the strategy of blocking the mechanism of angiogenesis may prove to be an effective therapeutic alternative for patients with nonsmall cell lung cancer. Clinical trials evaluating novel antiangiogenic agents, including antibodies to vascular endothelial growth factor (VEGF) and compounds directed at the tyrosine kinase receptor, are ongoing.

Abstract
Leucocytes are a major component of the tumour microenvironment. Recent studies have indicated that the infiltration and activity of these host cells are regulated by the tumour to promote its survival and progression. Through the production of an array of growth factors, proteases and angiogenic mediators, leucocytes in the tumour microenvironment promote tumour growth, angiogenesis and metastasis.

Abstract
Mast cells accumulate in angiogenesis-dependent situations of lung adenocarcinoma. Human mast cells are divided into two major subsets: MCT (mast cells with immunoreactivity for tryptase but not chymase) and MCTC (reactive for tryptase and chymase). Chymase is an important mediator of tissue remodeling, but research into chymase-containing mast cell subpopulations has been hampered by the lack of reagents suitable for use with formalin-fixed tissue. We stained chymase using CC1 antibody in 66 cases of small sized lung adenocarcinoma as well as CD34 and tryptase. There were significant positive correlations of microvessel counts with MCT-type and MCTC-type mast cell counts in lung adenocarcinomas. When analyzed according to Noguchi's classification, MCT-type and MCTC-type mast cells were significantly increased in Noguchi type-C tumors [localized bronchioloalveolar carcinoma (LBAC) with active fibroblastic proliferation] compared with in Noguchi type-A (LBAC) plus type-B tumors (LBAC with alveolar collapse). Members in the high-count group of MCTC-type but not MCT-type mast cells showed a significantly worse outcome than those in the low-count group in LBACs. Counting chymase-positive (MCTC-type) mast cells in tumor stroma may be a good prognosis predictor for LBACs, especially Noguchi type-C tumors.
