Abstract
Autocrine and paracrine loop involving vascular endothelial growth factor (VEGF) and its receptor have been described in haematological malignancies. However, scarce literature is present on angiogenesis in paediatric acute lymphoblastic leukemia (ALL) with studies showing controversial results. The aim was to study serum levels of VEGF and its receptors in paediatric ALL at the time of diagnosis and at the end of induction phase and to compare these levels with clinico-haematological parameters in these patients. Serum VEGF, VEGFR-1 and VEGFR-2 levels were measured by enzyme-linked immunoabsorbant assay at diagnosis (day 0) and at the end of induction phase (day 35) in 30 newly diagnosed paediatric ALL patients and in 10 healthy controls. Median s-VEGF was significantly lower at day 0 as compared to day 35 (196.15 vs. 606.75 pg/ml: p < 0.001). s-VEGFR-1 levels were detectable only in 7 patients at day 0 and were below detection level at day 35 in all patients. Median s-VEGFR-2 at day 0 was significantly lower as compared to day 35 (17,577.5 vs. 20,507.5 pg/ml; p = 0.005). Median VEGF-R1 showed an inverse relationship with VEGF-R2 but was statistically insignificant. All patients were in remission at the end of induction. Thus, leukemic infiltration of bone marrow affects angiogenesis and reduces pro-angiogenic markers VEGF and VEGFR-2 in serum possibly due to increased local consumption by blasts. A successful induction leads to clearing of blasts causing restoration of normal hematopoiesis with normalization of VEGF and VEGFR-2 levels.

Abstract
OBJECTIVE Febrile neutropenia (FN) represents a life-threatening complication in hematological malignancies. We aimed to analyze the utility of soluble vascular cell adhesion molecule 1 (sVCAM-1), intercellular adhesion molecule 1 (sICAM-1), vascular endothelial growth factor (VEGF) levels compared with C-reactive protein (CRP) and procalcitonin (PCT) during febrile neutropenia episodes of pediatric patients with leukemia. METHODS Two plasma samples, on day 0 (initial of episode) and day 3 (48-72 h after episode), for VCAM-1, ICAM-1 and VEGF, CRP and PCT were prospectively collected concomitantly during each febrile neutropenic episode between December 2016 and December 2017. The primary outcome was bacteremia and the secondary outcome was intensive care unit (ICU) admission. RESULTS Twenty-two (28.6%) acute lymphoblastic lymphoma (ALL), seventeen (22.1%) acute myeloblastic lymphoma (AML) patients and thirty-eight (49.3%) control patients with no known underlying disease or fever were included in this study. Of the 39 patients; 16 (41%) had bacteremia. Mean serum sVCAM1 and sICAM1 levels were significantly higher in control group, compared to FN patients (p < 0.001). Mean serum sVCAM2 level was significantly higher in FN patients with bacteremia compared to FN patients without bacteremia (144.97 ± 70.35 pg/mL vs 85.45 ± 53.76 pg/mL, p = 0.022). Mean sVCAM1 and 2 levels were higher in FN patients with ICU admission. In this study, we found that sVCAM-1 and VEGF, when combined to CRP and PCT, could predict gram-negative bacteremia in FN episodes of pediatric hematological malignancy. CONCLUSION Serum endothelial adhesion molecules, excluding sVCAM-1, cannot predict bacteremia and ICU admission alone in FN patients; but may be associated with clinical outcome when used with PCT and CRP.

Abstract
The microenvironment that surrounds a tumor, in addition to the tumor itself, plays an important role in the onset of resistance to molecularly targeted therapies. Cancer cells and their microenvironment interact closely between them by means of a molecular communication that mutually influences their biological characteristics and behavior. Leukemia cells regulate the recruitment, activation and program of the cells of the surrounding microenvironment, including those of the immune system. Studies on the interactions between the bone marrow (BM) microenvironment and Acute Lymphoblastic Leukemia (ALL) cells have opened a scenario of potential therapeutic targets which include cytokines and their receptors, signal transduction networks, and hypoxia-related proteins. Hypoxia also enhances the formation of new blood vessels, and several studies show how angiogenesis could have a key role in the pathogenesis of ALL. Knowledge of the molecular mechanisms underlying tumor-microenvironment communication and angiogenesis could contribute to the early diagnosis of leukemia and to personalized molecular therapies.

Abstract
High vascularization and locally secreted factors make the bone marrow (BM) microenvironment particularly hospitable for tumor cells and bones to a preferred metastatic site for disseminated cancer cells of different origins. Cancer cell homing and proliferation in the BM are amongst other regulated by complex interactions with BM niche cells (e.g. osteoblasts, endothelial cells and mesenchymal stromal cells (MSCs)), resident hematopoietic stem and progenitor cells (HSPCs) and pro-angiogenic cytokines leading to enhanced BM microvessel densities during malignant progression. Stress and catecholamine neurotransmitters released in response to activation of the sympathetic nervous system (SNS) reportedly modulate various BM cells and may thereby influence cancer progression. Here we review the role of catecholamines during tumorigenesis with particular focus on pro-tumorigenic effects mediated by the BM niche.

Abstract
Endothelial dysfunction is considered as a universal non-specific link in the pathogenesis of many diseases, primarily the cardiovascular system. This review is devoted to the discussion of the main functions of the endothelium and mechanisms for their implementation. One of the most striking features of endothelial cells is their morphological heterogeneity, which allows us to identify several typical forms of endothelial dysfunction (vasomotor, hemostatic, adhesion and angiogenous). Also, the review presents the most promising predictors of cardiovascular diseases and their complications among endothelial damage markers.

Abstract
Introduction Vascular endothelial growth factor A (VEGFA) is a key proangiogenic cytokine. The role of angiogenesis in acute lymphoblastic leukemia (ALL) is still unclear. The purpose of the study was to assess angiogenesis in children with ALL based on serum VEGFA level determined at diagnosis and at remission with further participant subdivision into different risk groups. Materials and Methods Forty children, aged 3-12 years (mean age: 8 years) with newly diagnosed ALL, were enrolled in the study. The control group (Group C) was twenty healthy children. According to the risk assessment, they were classified into a standard-risk group, an intermediate-risk group (IRG), or a high-risk group (HRG). Results The median serum VEGFA levels at diagnosis were significantly higher in IRG and HRG as compared to Group C. The VEGFA levels at remission were significantly higher in all study groups, as compared to Group C. The differences in median values of serum VEGFA levels between the study groups both at diagnosis and at remission were not statistically significant. Conclusions The angiogenesis in ALL seems to be intensified at diagnosis as a result of neoplasmatic bone marrow rebuilding and at remission as its intensive recovering.

Abstract
OBJECTIVE Angiogenesis have implications in leukemia biology. Angiopoietin 1 (Ang 1) is an angiogenic cytokine which is essential in survival and proliferation of endothelial cells. Angiopoietin 2 (Ang 2) promotes dissociation of pericytes and increases vascular permeability and stromal derived factor 1 alpha (SDF 1α) which is a key player in stem cell traffic in the bone marrow (BM), has stimulating effects on angiogenesis as well. Here, we investigated the role of the leukemic BM microenvironment and specifically, the role of SDF 1α-CXCR4 and Ang 1/Ang 2-Tie 2 axes. METHODS Here, Ang 1, Ang 2, and SDF 1α levels were measured in the BM plasma and in supernatants of mesenchymal stem/stromal cells (MSCs) of patients with ALL and compared with those of healthy controls. RESULTS The results showed that at diagnosis, BM plasma levels of Ang 1 and SDF 1α were significantly low and Ang 2 was high when compared to control values. Remission induction was associated with an increase in Ang 1/Ang 2 ratio and SDF levels in BM plasma. DISCUSSION The results suggest that BM microenvironment and leukemic cell-stroma interaction influences the secretion of Ang 1, 2 and SDF 1α, thus, may affect both angiogenesis, homing and mobilization of leukemic blasts.

Abstract
Angiogenesis, the process of blood vessel formation, is necessary for tissue survival in normal and pathologic conditions. Increased angiogenesis in BM niche is correlated with leukemia progression and resistance to treatment. Angiogenesis can interfere with disease progression and several angiogenic (such as vascular growth factors) as well as anti-angiogenic factors (i.e. angiostatin) can affect angiogenesis. Furthermore, miRs can affect the angiogenic process by inhibiting angiogenesis or increasing the expression of growth factors. Given the importance of angiogenesis in BM for maintenance of leukemic clones, recognition of angiogenic and anti-angiogenic factors and miRs as well as drug resistance mechanisms of leukemic blasts can improve the therapeutic strategies. We highlight the changes in angiogenic balance within the BM niche in different leukemia types. Moreover, we explored the pathways leading to drug resistance in relation to angiogenesis and attempted to assign interesting candidates for future research.

Abstract
It was believed that vasculogenesis occurred only during embryo life and that postnatal formation of vessels arose from angiogenesis. Recent findings demonstrate the existence of Endothelial Precursor Cells (EPCs), which take partin postnatal vasculogenesis. EPCs are recruited from the bone marrow under the stimulation of growth factors and cytokines and reach the sites of neovascularization in both physiological and pathological conditions such as malignancies where they contribute to the “angiogenic switch” and tumor progression. An implementation of circulating EPCs in the bloodstream of patients with haematological malignancies has been demonstrated. This increase is strictly related to the bone marrow microvessel density and correlated with a poor prognosis. The EPCs characterization is a very complex process and still under investigation. This literature review aims to provide an overview of the functional and biological role of EPCs in haematological malignancies and to investigate their potential as a new cancer therapeutic target.

Abstract
Fibroblast growth factor 2 (FGF-2) plays an important role in the early phases of bone healing. In this study, we measured FGF-2 serum levels in 88 children undergoing surgical treatment for congenital (n = 49) or acquired (n = 39) orthopedic conditions, which were associated (n = 35) or not (n = 53) with bone lesions, to assess whether serum levels of FGF-2 varied according to the underlying disease and may predict clinical outcomes. FGF-2 serum levels were significantly lower in patients who did not heal after surgery (p = 0.008). Diagnostic accuracy was validated statistically, and the ROC curve provided a threshold value useful in discriminating good versus poor outcomes. The relationship between FGF-2 and bone healing was supported by in vitro experiments. A mineralization assay was performed on bone marrow stromal cells from three patients with congenital pseudarthrosis, who had low serum levels of FGF-2 and a poor clinical outcome after surgical treatment. Autologous serum alone was not sufficient to induce in vitro mineralization, but it did occur when cells were cultured with different sources of exogenous growth factors (GFs), including recombinant FGF-2 and homologous serum collected from children with fractures, high FGF-2 levels, and a good clinical outcome. In conclusion, our findings suggest that osteoinductive GFs are essential for bone repair, and that the amount of circulating FGF-2 may predict bone healing.

Abstract
OBJECTIVE To evaluate serum vascular endothelial growth factor (VEGF) levels in children with acute lymphoblastic leukemia (ALL) during the induction phase of chemotherapy. DESIGN Prospective sudy. SETTING Setting: Hospital-based study over 18 months. PATIENTS 30 children with ALL and 17 healthy age- and sex-matched controls. INTERVENTION Serum concentration of VEGF-A-165 isoform (s-VEGF) was measured by enzyme-linked immunoabsorbant assay at diagnosis and at the end of induction chemotherapy. MAIN OUTCOME MEASURES s-VEGF was compared with markers of tumor burden. Kinetics of s-VEGF was assessed in response to induction chemotherapy. RESULTS Median VEGF was significantly lower in untreated patients than in controls (17.0 vs. 42.6 pg/mL, P=0.004). s-VEGF levels were fairly correlated with WBC count (r=-0.56, P=0.004) and LDH (r=-0.52, P=0.02) at diagnosis. All patients but one were in morphologic remission at the end of induction. Median s-VEGF concentration on day 29/33 was significantly higher than on day 1 (44.2 pg/mL, P=0.009). CONCLUSIONS Untreated children with ALL have significantly lower s-VEGF concentration than controls. At the end of the induction therapy, s-VEGF increased to levels similar to controls. The role of ligand-receptor interaction between VEGF and VEGF receptors on leukemia cells needs to be further delineated.To identify the risk factors for scholastic backwardness in children.

Abstract
INTRODUCTION Data on angiogenesis in pediatric patients with malignancy are scarce. Our aim was to study angiogenic growth factors vascular endothelial growth factor (VEGF) and angiopoietin-2 (Ang2) in pediatric oncological patients at diagnosis and a few months after the beginning of the therapy. PATIENTS AND METHODS Eighty-four consecutive patients with malignancy were included in this study. The levels of plasma and bone marrow VEGF and Ang2 were analyzed by enzyme-linked immunosorbent assay. RESULTS The levels of VEGF were higher in patients with solid tumors than in patients with leukemias (P=0.003), whereas Ang2 concentrations showed the opposite (P=0.003). Interestingly, the plasma concentrations of both VEGF and Ang2 correlated with concentrations in the bone marrow (P<0.05). Leukemia patients with lower VEGF level and patients with higher Ang2 level at follow-up had longer event-free survival than other patients (P=0.032 and 0.053, respectively). DISCUSSION The results of our study enlighten the behavior of 2 different angiogenic factors in pediatric patients with malignancy. An interesting finding was the connection between survival of pediatric leukemia patients and angiogenic factor levels a few months after the beginning of therapy. Pathophysiology and clinical applications of these findings need further studies.

Abstract
Angiogenesis plays an important role in solid tumor growth, progression and metastasis. Evidence suggests that the progression of hematolymphoid malignancies also depends on the induction of new blood vessel formation under the influence of acute leukemia, myelodysplastic syndromes, myeloproliferative neoplasms, multiple myeloma and lymphomas. The vascular endothelial growth factor (VEGF) is the most important proangiogenic agent that activates receptors on vascular endothelial cells and promotes blood vessel regeneration. It has been demonstrated that VEGF/VEGF receptor (VEGFR) expression is upregulated in several types of hematolymphoid tumor cells accompanied with angiogenesis. The levels of VEGF/VEGFR are correlated with the treatment, relapse and prognosis of hematolymphoid tumors. In order for VEGF family and their receptors as antiangiogenic targets to treat solid tumors, several antiangiogenic agents targeting VEGF-related pathways have been used for the treatment of hematolymphoid malignancies in clinical trials. The results demonstrate a promising therapeutic intervention in multiple types of hematolymphoid tumors. This review aims to summarize recent advances in understanding the role of VEGF and angiogenesis in leukemias, mainly focusing on their upstream transcriptors, downstream targets and the correlation of VEGF/VEGFR with the treatment, relapse or prognosis of leukemia. The progress of VEGF and its receptors as attractive targets for therapies are also discussed in clinical application.

Abstract
The role of angiogenesis in acute leukaemia has been discussed since the cloning of the gene of vascular endothelial growth factor (VEGF) from the acute myelogenous leukemia cell line (HL60) and, thereafter, when the first studies reported increased bone marrow vascularity and elevation of angiogenic cytokines in acute lymphoblastic leukaemia (ALL). VEGF and basic fibroblast growth factor (bFGF) are the major proangiogenic cytokines that have been studied, and evaluation of their prognostic impact in childhood ALL has been reported in several studies, though with controversial results. The antiangiogenic response, contributing to the angiogenic balance, has scarcely been reported. The origin of the factors, their prognostic value, and their relevance as good markers of what really happens in the bone marrow are discussed in this paper. The place of antiangiogenic drugs in ALL has to be defined in the global treatment strategy.

Abstract
Vascular endothelial growth factor (VEGF) seems to play a central role in angiogenesis-lymphangiogenesis in hematological malignancies. There are limited data related to childhood hematologic malignancies. The aim of the study was to evaluate soluble VEGF (sVEGF) levels in children with acute leukemia and malignant lymphoma (ML) at diagnosis and in remission. The levels of serum sVEGF were measured by enzyme-linked immunosorbent assay (ELISA) in 20 children with acute leukemia, 33 children with different histopathological subtypes of ML, and 20 healthy controls. The levels of sVEGF at diagnosis (range 2 -1040 pg/mL; median 52 pg/mL) was significantly lower than in remission (range 136 -1960 pg/mL; median 630 pg/mL) in acute myeloid leukemia (AML) group (P = .018). The sVEGF levels at diagnosis (range: 2 -640 pg/mL; median 89 pg/mL) was significantly lower compared to remission values (range: 116 -1960 pg/mL; median 136 pg/mL) in patients with acute lymphoblastic leukemia (ALL) (P = .002). In ML group, including Burkitt's lymphoma (BL), T-cell non-Hodgkin's lymphoma (NHL), and Hodgkin's lymphoma (HL), sVEGF levels at diagnosis were higher than remission levels, but there was no statistically significant difference (P >.05). On the other hand, there were significant difference between levels in active disease and control group, ie, BL versus control, T-cell NHL versus control, and HL versus control (P = .008, P = .043, P = .007, respectively). The authors noticed that sVEGF levels showed distinct behavioral pattern in different childhood malignancies at diagnosis and in remission. In acute leukemia and ML patients, VEGF acts through different pathophysiological mechanisms, in both bone marrow (BM) angiogenesis and lymphoid tissue lymphangiogenesis.

Abstract
Increased angiogenesis is observed both in the inflammatory and in the neoplasmatic tissue. The aim of the study was to assess the diagnostic significance of serum concentration of vascular-endothelial growth factor (sVEGF) and basic fibroblast growth factor (sbFGF) in the various forms of lymphadenopathy in children. Ninety-four children with lymphadenopathy were studied: group A, 52 patients with lymphadenitis; group B, 42 patients with lymphomas. Group B was divided into subgroups: B(P), children with lymphomas in peripheral lymph nodes and B(M), children with lymphomas in peripheral lymph nodes and mediastinal tumor. The healthy control group was 20 children. Using enzyme-linked immunosorbent assays the authors quantified VEGF and bFGF in serum of healthy children and of children with lymphadenopathy. The sVEGF in group A was significantly higher than controls (313.8 versus 44.6 pg/mL; P <.05) and in group B was 633.4 pg/mL and was significantly higher than controls (P <.0001). The sVEGF and bFGF in group A versus subgroup B(P) were significantly lower (P(VEGF) <.05, P(bFGF) <.05), and sVEGF in subgroup B(P) versus B(M) was significantly lower (P <.05). These results show that the evaluation of serum VEGF concentration might be useful as noninvasive diagnosis of some chronic peripheral lymphadenopathies in children.

Abstract
New blood vessel formation (angiogenesis) is not only essential for the growth of solid tumors but there is also emerging evidence that progression of hematological malignancies like multiple myeloma, acute leukemias, and myeloproliferative neoplasms, also depends on new blood vessel formation. Anti-angiogenic strategies have become an important therapeutic modality for solid tumors. Several anti-angiogenic agents targeting angiogenesis-related pathways like monoclonal antibodies, receptor tyrosine kinase inhibitors, immunomodulatory drugs, and proteasome inhibitors have been entered clinical trials or have been already approved for the treatment of hematological malignancies as well and in some instances these pathways have emerged as promising therapeutic targets. This review summarizes recent advances in the basic understanding of the role of angiogenesis in hematological malignancies and clinical trials with novel therapeutic approaches targeting angiogenesis.

Abstract
Angiogenesis is essential for malignant tumor growth. This has been documented for solid tumors, and there is an emerging evidence suggesting that tumor progression of hematolymphoid malignancies also depends on the induction of new blood vessel formation. The most important proangiogenic agent is vascular endothelial growth factor (VEGF), activating VEGF receptors 1 and 2. The available data on angiogenesis in hemato-lymphoid malignancies, such as acute leukemias, myelodysplastic syndromes, myeloproliferative neoplasms, multiple myeloma, and lymphomas, point towards the significance of autocrine and paracrine VEGF-mediated effects for proliferation and survival of leukemia/lymphoma cells in addition to tumor vascularization. Antiangiogenic strategies have become an important therapeutic modality for solid tumors. Several antiangiogenic agents targeting VEGF-related pathways are also being utilized in clinical trials for the treatment of hemato-lymphoid malignancies, and in some instances these pathways have emerged as promising therapeutic targets. This review summarizes recent advances in the basic understanding of the role of angiogenesis in hemato-lymphoid malignancies and the translation of such basic findings into clinical studies.

Abstract
BACKGROUND The significance of vascular endothelial growth factor (VEGF) and heat shock protein-90 (HSP90) has received only limited attention especially in acute lymphoblastic leukemia (ALL). In this study, we assessed expressions of HSP90 and VEGF in bone marrow samples of patients with ALL and effect of these expression quantities on the mean overall survival. PATIENTS AND METHODS Using immunohistochemical methods, we assessed expression of HSP90 and VEGF in 22 cases of ALL. RESULTS Expression of HSP90 was detected in 19/22 (86.4%) and 3/22 (13.6%) of patients with ALL, for strongly positive and moderate-weakly positive, respectively. Negative HSP90 expression was not detected in patients with ALL. Expression of HSP90 in patients with ALL and in control group were statistically significant (P<0.001), however, did not reflect the mean overall survival (P=0.910). Mean OS was evaluated 992±181 and 724.8±88.2 days for moderate-weak and high HSP90 expression, respectively. VEGF expressions were not significantly different between ALL and control groups (P<0.087). We did not find any relationship between HSP90 and VEGF expressions in bone marrow specimens of patients with ALL. CONCLUSION This study demonstrated that HSP90 expression grades in patients with ALL were significantly higher than that in controls and presence of strong HSP90 expression was associated with worse overall survival. VEGF expression in patients with ALL was not different from that in control samples. Determination HSP90 with immunohistochemical method in bone marrow can provide information about prognosis.

Abstract
BACKGROUND Angiogenesis and proangiogenic cytokines are involved in neoplastic development. The role of these processes in lymphoma formation has not been established. The aim of the study was to assess angiogenesis on the basis of serum levels of vascular-endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in childhood lymphomas. The prognostic value of these parameters was determined in the examined children. PROCEDURE Forty-two children with lymphomas (Hodgkin and non-Hodgkin Lymphomas) were studied (group A). Group A was divided into two subgroups: A(CR)-30 children with complete remission (CR) and A(PR+P+ER)-12 children with partial remission (PR), progressive disease (P), and early relapse (ER). The control group (group C) consisted of healthy 20 children. Using enzyme-linked immunosorbent assays we quantified VEGF and bFGF in serum of the healthy children and of the children with lymphomas. RESULTS The serum VEGF concentration in group A was 633.4 pg/ml (24.0-1,210.5) and was significantly higher (P = 0.0001) in comparison with group C (144.6 pg/ml; 32.3-734.8). In subgroup A(PR+P+ER), the baseline serum VEGF concentration was 865.0 pg/ml (205.8-1,209.2) and was significantly higher (P = 0.02) than in subgroup A(CR) (564.0 pg/ml; 24.0-1,210.5). The high serum VEGF concentration in children with lymphomas was the only independent risk factor for treatment failure (OR = 8.64; 95 CI: 1.51-49.34; P = 0.01). The cutoff point for the serum VEGF level >or=633.4 pg/ml as a parameter predicting treatment failure was established (P = 0.01). CONCLUSION Baseline serum VEGF concentration constitutes a prognostic marker for the progression of Hodgkin and non-Hodgkin Lymphomas in children.

Abstract
Perturbation in the expression and signaling pathways of vascular endothelial growth factor (VEGF) has been linked to pathogenesis of hematologic malignancies. We investigated the expression and clinical importance of VEGF and two of its receptors, VEGFR-1 and VEGFR-2, in childhood precursor B-cell acute lymphoblastic leukemia (pre-B ALL) by using immunohistochemistry. These angiogenic proteins were expressed in the majority of leukemic bone marrow samples. Notably, pre-B ALL patients had significantly increased expression of VEGFR-1 compared with no expression in the nonmalignant group, indicating a link between VEGFR-1 protein expression and pre-B ALL. These novel findings suggest that VEGFR-1 may have clinical importance in childhood pre-B ALL.

Abstract
The issue of angiogenesis and its clinical relevance in childhood acute lymphoblastic leukaemia (ALL) is controversial. In the present study, microvessel density (MVD), analysed in 185 diagnostic bone marrow biopsies, was higher in T-cell ALL compared to B-cell precursor (BCP)-ALL (P = 0.013). In the BCP group, cases with t(12;21) were characterized by a low MVD while patients with high-hyperdiploid leukaemia (HeH, 51-61 chromosomes) showed a high MVD compared to other BCP patients (P = 0.001 and 0.002 respectively). There was a correlation between MVD and white blood cell (WBC) count in high-risk BCP patients (P = 0.021). In addition, BCP patients with a high marrow reticulin fibre density and high MVD had an unfavourable outcome compared to the other BCP patients (P = 0.002). The fraction of vessels in which lumina were filled with blasts (blast congested vessel fraction) correlated strongly with WBC count (P < 0.001). These findings indicate that the angiogenic process interacts with other stroma-factors, such as reticulin fibre density, in its effect on outcome, and is coupled to both the ALL genotype and phenotype. One possible implication is that different subtypes of childhood ALL may respond differently to anti-angiogenic drugs as a supplement in first-line treatment.

Abstract
PURPOSE Many molecular pathways, including cell cycle control, angiogenesis, and drug resistance, mediate tumor growth and survival. Vascular endothelial growth factor-A (VEGF-A) serum levels <40 and >100 pg/mL have been associated with good and poor prognoses, respectively. EXPERIMENTAL DESIGN The hypothesis was that serum VEGF-A levels in standard-risk acute lymphoblastic leukemia pediatric patients at induction are predictive of event-free survival (EFS). One hundred seventeen patients were entered in CCG-1962 study and randomized into the native and polyethylene glycolated asparaginase arms. VEGF-A levels were quantified by an ELISA assay. RESULTS All patients had a decrease in VEGF-A levels by day 14 of induction, but they later dichotomized; EFS group levels remained low and event group levels increased. A correlation exists between high VEGF-A levels at entry to induction and time to event. Moreover, 6-year EFS patients have lower end of induction VEGF-A levels (28 +/- 6 pg/mL) than event patients (>100 pg/mL; P < 0.01). Kaplan-Meier curves using various VEGF-A values were produced; with < or =30 at entry into induction (day 0) and < or =60 pg/mL at the end of induction (day 28), patients with low VEGF-A levels had superior EFS (P < 1e-4). Furthermore, patients who had an increase in VEGF-A during induction (DeltaVEGF-positive, days 0-28) were more likely to have an event (P < 1e-4). Bifurcation by asparaginase treatment arm did not alter these results. CONCLUSIONS These observations strongly support that high VEGF-A levels in induction are an asparaginase treatment-independent predictive marker for EFS. Hence, an anti-VEGF-A therapy should be tested in acute lymphoblastic leukemia.

Abstract
Angiogenesis is an important event in the survival and progression of solid tumors. The angiogenic status and the exact role of the angiogenic cytokines in lymphoid leukemia has not been fully elucidated. We have investigated the profile of the systemic components of angiogenic regulation in B-lineage acute lymphoblastic leukemia (B-ALL) and B-chronic lymphocytic leukemia (B-CLL), namely vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha (TNF-alpha), endostatin and matrix metalloproteinase-9 (MMP-9) using enzyme-linked immunosorbent assay (ELISA). In B-ALL patients, sVEGF, and MMP-9 were significantly lower than control levels at diagnosis (p < 0.001) and increased to near control levels in remission (p>0.05). Both serum TNF-alpha and endostatin levels showed no significant difference at diagnosis (p>0.05) and in remission (p>0.05) compared to control levels. VEGF, TNF-alpha, MMP-9 and endostatin levels were not significantly correlated with peripheral white cell count or bone marrow blast cell count, but were positively correlated with platelet count. In B-CLL patients, serum VEGF, MMP-9 and TNF-alpha were significantly higher (p < 0.001 = 0.009, 0.007, respectively) and decreased to near control levels in remission (p>0.05 for all). Serum endostatin levels showed no significant difference at diagnosis and in remission compared to control levels (p>0.05). A significant positive correlation between VEGF, TNF-alpha, MMP-9 and peripheral white cell counts, bone marrow lymphocytic count and platelets count were found. In conclusion, our data suggest that the driving forces of angiogenic factors (VEGF, TNF-alpha and MMP-9) in adult B-ALL appears different from that in B-CLL patients.

Abstract
Data obtained from animal models, and partially confirmed in pre-clinical studies, have provided clear evidence of the importance of angiogenesis for the growth of solid tumors. Similarly, in hematological cancers such as leukemias and lymphomas, the role of angiogenesis has been under intense scrutiny. However, the molecular singularities of leukemia, namely its cellular origin, have suggested a putative role for angiogenesis in these tumors may have distinct features. We and others have shown acute leukemia cells use angiogenic growth factor signaling pathways, namely those activated by vascular endothelial growth factor (VEGF) in autocrine and paracrine fashion. Autocrine and paracrine VEGF stimulation of subsets of leukemias results in cell proliferation, increased survival and migration. This review discusses recent advances in the field of leukemia angiogenesis, focusing on the role of VEGF and its receptors, acting in a paracrine or autocrine manner. We also briefly describe some of the novel anti-angiogenic compounds, namely VEGF blockers, and suggest their use to treat subsets of hematological malignancies may have clinical benefit.

Abstract
PURPOSE Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) are associated with increased angiogenesis, growth, and metastasis in solid tumors. But, until today, the importance of theses factors on leukemia, especially childhood acute lymphocytic leukemia (ALL) has received limited attention. Therefore, this study examined the bone marrow plasma VEGF and bFGF levels in ALL patients and normal controls. PATIENTS AND METHODS Bone marrow plasmas at diagnosis from 33 ALL patients (median age 5.9 years; range 1.8-13.9 years) were used for analysis. The bone marrow levels of bFGF and VEGF were determined by enzyme-linked immunosorbent assay (R & D Systems) and compared with the bone marrow levels of 7 healthy control subjects (median age 11.98 years; 6 months -13.6 years). RESULTS Average VEGF was higher in relapse ALL (N=7, 216.6 +/- 79.9pg/mL) compared to standard (N=9, 36.8 +/- 12.1pg/mL) (p=0.013) or high risk ALL (N=17, 80.0 +/- 12.2pg/mL) (p=0.023). bFGF levels were also significantly higher in relapse than standard-, or high-risk ALL patients (relapse ALL; 48.6 +/- 15.4pg/mL, standard risk ALL; 18.9 +/- 5.5pg/mL, high risk ALL; 19.0 +/- 3.5pg/mL, normal control; 18.6 +/- 4.0pg/mL) (p=0.003). Three patients with refractory relapse and death had much higher VEGF and bFGF values (VEGF; 420.0 +/- 81.6pg/ mL, bFGF; 85.6 +/- 3.2pg/mL). CONCLUSION Our data suggest that the increased levels of VEGF and bFGF in bone marrow may play an important role in prognosis of childhood ALL.

Abstract
Angiogenic factors such as basic fibroblast growth factor (bFGF) or vascular endothelial growth factor (VEGF) were previously studied in childhood acute lymphoblastic leukaemia (ALL) but little is known concerning the anti-angiogenic response in ALL. At diagnosis, the plasma levels of the anti-angiogenic factor endostatin were significantly higher in 33 children with ALL than in controls (median values 17.7 and 7.6 ng/ml, respectively, p=0.0192) but no relationship was observed with plasma bFGF or VEGF levels. The highest levels were observed in patients with an hyperdiploïd karyotype. Expression of mRNA for collagen XVIII/endostatin in lymphoblasts was detected in 19/24 cases but protein secretion was found only in 14/28 supernatants of cultured lymphoblasts. No direct relationship appeared between secretion of endostatin by lymphoblasts and plasma levels. In addition, endostatin levels remained elevated in remission, suggesting that endostatin could have a stromal origin as well. No prognostic value of plasma endostatin could be assessed. In conclusion, the present data indicate that an anti-angiogenic response is observed in some ALL children, but its physiopathological importance remains to be established.

Abstract
Angiogenesis plays an important role in solid tumors and hematologic malignancies. The prognostic significance of angiogenic factors in adult acute lymphoblastic leukemia (ALL) remains ambiguous. We therefore analyzed the impact of angiogenic factor levels on overall survival of newly diagnosed adult ALL patients. Plasma levels of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), interleukin-1 receptor alpha (IL-1Ralpha), IL-6, IL-8, VEGF receptors VEGFR1 and VEGFR2, and thrombopoietin (TPO) were measured in plasma samples of 95 patients by enzyme-linked immunosorbent assay (ELISA). In a univariate Cox proportional hazards model, higher levels of IL-1Ralpha, IL-8, VEGFR1, and VEGFR2 were predictive of poor survival. In contrast, higher levels of VEGF were predictive of longer survival, and higher levels of bFGF suggested a similar trend (P = .09). The multivariate model simultaneously included VEGF (relative risk [RR] for death, 8.01; P = .001 for levels less than or equal to 19.5 pg/mL), IL-1Ralpha (RR, 5.12; P = .007 for levels greater than 373 pg/mL), and VEGFR2 (RR, 4.01; P = .04 for levels greater than 8222 pg/mL) as independent factors for survival. Of interest is the association of high levels of VEGF with good prognosis and higher levels of VEGF receptors with poor outcome. These data reflect the complexity by which angiogenic factors may affect the clinical behavior of patients with ALL, and this complexity should be considered in any therapeutic strategy incorporating antiangiogenic agents.

Abstract
Angiogenesis was estimated in childhood acute lymphoblastic leukemia (ALL) by the use of a novel morphometric method. This was compared with the widely used one of microvessel density (MVD). Bone marrow biopsies were evaluated by immunostaining with anti-Factor VIII related antigen (FVIIIRAg). Angiogenesis was calculated as volume corrected microvessel density index (VC-MVDI), taking into account the bone marrow cellularity. According to our results both MVD and VC-MVDI were increased at diagnosis of ALL in comparison with the control group. However the VC-MVDI increment was not statistically significant. Therefore, VC-MVDI could be more representative of the true increase of angiogenesis, correlating better with the outcome of the disease.

Abstract
Antiangiogenic gene therapy offers an attractive approach to the treatment of a variety of malignancies, including those of the hematological system. However, evaluation of this approach has been hampered by the lack of appropriate animal models. We have recently produced transgenic mice expressing P230 bcr/abl that develop myeloproliferative disease (MPD) closely resembling human chronic myelogenous leukemia. Using this MPD murine model, we examined the feasibility of systemic antiangiogenic gene therapy for hematological malignancy. An adenoviral vector containing the secretable endostatin gene was injected into the right quadriceps muscle of the MPD mice. The increased endostatin level was detected for at least 6 months. Hematological parameters including platelet counts, granulocyte counts, and the hemoglobin concentration were improved by this gene therapy. Infiltration of megakaryocytes was also significantly inhibited in treated MPD mice. Reduction of the microvessel density was confirmed by histological examination. These results demonstrated, for the first time, that antiangiogenic gene therapy is effective to inhibit leukemogenesis caused by expression of the chimeric bcr/abl gene.

Abstract
Vascular endothelial growth factor (VEGF), basic-fibroblast growth factor (bFGF), hepatocyte growth factor (HGF), and angiogenin are important angiogenic factors. In 65 patients with non-Hodgkin's lymphoma (NHL), pre-treatment VEGF, bFGF, and HGF levels were significantly elevated compared to normal individuals, while angiogenin levels were significantly subnormal. In 37 patients with Hodgkin's disease, pre-treatment levels of VEGF and HGF were significantly elevated, bFGF levels were normal, and angiogenin levels were significantly subnormal. In patients with NHL, post-therapy levels of angiogenin were independently predictive of survival. Both pre-therapy and post-therapy VEGF levels were independently predictive of survival in patients with HD.

Abstract
Although childhood Hodgkin disease is sensitive to the treatment regimens devised for Hodgkin disease in adults, long-term toxicity is enhanced in the developing individual. As a result, there have been dual goals in the design of clinical trials for pediatric Hodgkin disease: 1) to reduce long-term organ injury; and 2) to increase efficacy. Radiation dose and field has been reduced by enhanced reliance on chemotherapy, thus limiting the risks of hypoplasia, hypothyroidism, secondary cancers, and valvular and atherosclerotic heart disease. Multiagent, chemotherapeutic regimens for children have been developed to avoid the risks of sterility, leukemia, and cardiopulmonary toxicity. Newer approaches advocate for early dose intensity to limit cumulative therapy using response-based paradigms. Targeting molecular mechanisms specific for the Reed-Sternberg cell may allow for less toxic and more efficacious treatments in the future.
