Abstract
Worldwide, gastric cancer (GC) is the fifth most commonly diagnosed malignancy. It has a reduced prevalence but has maintained its poor prognosis being the fourth leading cause of deaths related to cancer. The highest mortality rates occur in Asian and Latin American countries, where cases are usually diagnosed at advanced stages. Overall, GC is viewed as the consequence of a multifactorial process, involving the virulence of the Helicobacter pylori (H. pylori) strains, as well as some environmental factors, dietary habits, and host intrinsic factors. The tumor microenvironment in GC appears to be chronically inflamed which promotes tumor progression and reduces the therapeutic opportunities. It has been suggested that inflammation assessment needs to be measured qualitatively and quantitatively, considering cell-infiltration types, availability of receptors to detect damage and pathogens, and presence or absence of aggressive H. pylori strains. Gastrointestinal epithelial cells express several Toll-like receptors and determine the first defensive line against pathogens, and have been also described as mediators of tumorigenesis. However, other molecules, such as cytokines related to inflammation and innate immunity, including immune checkpoint molecules, interferon-gamma pathway and NETosis have been associated with an increased risk of GC. Therefore, this review will explore innate immune activation in the context of premalignant lesions of the gastric epithelium and established gastric tumors.

[PMID: 36601631 PMCID: PMC9806434 DOI: 10.1177/17588359221141307] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Accepted: 11/07/2022] [Indexed: 12/28/2022] Open
Abstract
Background Several studies have reported the impact of single nucleotide polymorphisms (SNPs) in vascular endothelial growth factor (VEGF) pathway genes on the efficacy of bevacizumab in metastatic colorectal cancer (mCRC), but results are still inconsistent. The PRODIGE 9 phase III study compared bevacizumab maintenance versus observation alone after induction chemotherapy with FOLFIRI plus bevacizumab. Objective We evaluated the impact of SNPs of VEGF-A, VEGF receptors (VEGFR-1, VEGFR-2), and hypoxia inducible factor-1α (HIF-1α) on tumor control duration (TCD), overall survival (OS), progression-free survival (PFS), and duration of first chemotherapy free-intervals (CFI). Patients and methods We included 314/491 patients from PRODIGE 9 with a DNA blood sample available. Nine SNPs were genotyped on germline DNA using real-time Polymerase Chain Reaction TaqMan TM (Thermo Fisher Scientific, Waltham, MA , USA 02451). Results In the bevacizumab arm, patients with the VEGFR-1 rs9582036 CC genotype (n = 14) had significantly longer TCD [22.4 months (95% confidence interval (CI): 14.75-not reached)] than patients with the AA or CA genotype [14.4 months (95% CI: 11.7-17.1)] (p = 0.036), whereas there was no significant difference in the observation arm. In the bevacizumab arm, no significant difference was found between the CC, and AA or CA genotype for OS [28.2 (95% CI: 18.1-42.8) versus 22.5 (95% CI: 18.6-24.6) months, p = 0.5], PFS [9.4 (95% CI: 7.2-11.3) versus 9.2 (95% CI: 8.71-10.1)], and duration of the first CFI [4.6 (95% CI: 1.6-13.3) versus 4.14 (95% CI: 0.5-29.0) months, p = 0.3]. Conclusion Among mCRC patients treated with bevacizumab maintenance, those with the VEGFR-1 rs9582036 CC genotype experienced longer TCD. The presence of this genotype may thus predict a benefit of bevacizumab maintenance in mCRC.

Abstract
In observational studies, circulating vascular endothelial growth factor (VEGF) has been reported to be associated with certain types of cancer. The purpose of this study was to verify whether there is a causal relationship between circulating VEGF and different types of cancer and the direction of the causal relationship. Summary statistical data were obtained from the corresponding genome-wide association studies (GWASs) to investigate the causal relationship between circulating VEGF and the risk of several cancers, including breast cancer, ovarian cancer, lung cancer, colorectal cancer, anus and anal canal cancer, prostate cancer, esophageal cancer, kidney cancer, bladder cancer, thyroid cancer, malignant neoplasm of the brain and malignant neoplasm of the liver and intrahepatic bile ducts. A two-sample bidirectional Mendelian randomization (MR) analysis and sensitivity tests were used to evaluate the validity of causality. A causal relationship was detected between circulating VEGF and colorectal cancer (OR 1.21, 95% CI 1.11–1.32, p < 0.000) and colon adenocarcinoma (OR 1.245, 95% CI 1.10–1.412, p < 0.000). Suggestive evidence of association was detected in VEGF on malignant neoplasms of the rectum (OR 1.16, 95% CI 1.00–1.34, p = 0.049). No causal relationship was found between circulating VEGF and other types of cancer, nor was there a reverse causal relationship from tumors to VEGF (p > 0.05). Circulating VEGF has a causal relationship with specific types of cancer. Our findings highlight and confirm the importance of circulating VEGF in the prevention and treatment of colorectal cancer.

Genes (Basel) 2022; 13:genes13071235.

Abstract
Differential genetically determined expression of transforming growth factor-β (TGF-β pathway and of vascular endothelial growth factor-A (VEGF-A) might modulate the molecular “milieu” involved in the etio-pathogenesis of non-melanoma skin cancer (NMSC). We have evaluated the frequency of some functionally relevant SNPs of TGF-β and VEGF-A genes in 70 NMSC patients and 161 healthy controls, typed for TGF-β1 rs1800471, TGF-β2 rs900, TGF-βR1 rs334348 and rs334349, TGF-βR2 rs4522809 and VEGF-A rs3025039 SNPs. TGF-βR2 rs1800629G allele and related genotypes were found to be associated with a possible protective role against NMSC, whereas VEGF-A rs3025039T was associated with an increased risk. To evaluate the effect of genotype combinations on NMSC susceptibility, we determined the frequencies of 31 pseudo-haplotypes due to non-random linkage among alleles of loci not lying on the same chromosome. Two pseudo-haplotypes that imply a minor allele of TGF-βR2 or minor allele of VEGF-A SNPs combined with major alleles of the other SNPs were, respectively, associated with a protective effect, and susceptibility to NMSC. In addition, a pseudo-haplotype involving minor alleles of TGF-β2 rs900, TGF-βR1 rs334348 and rs4522809 SNPs might be a susceptibility marker for NMSC. In conclusion, our data suggest that a complex interplay among the genetic polymorphisms of TGF-β, TGF-β receptors and VEGF-A genes might influence the net effect of genetic background of the patients on NMSC development. This might be relevant in the risk evaluation, diagnosis and treatment of NMSC.

Abstract
BACKGROUND Angiogenesis play a critical role in the development and progression of tumors in solid tumors. Vascular endothelial growth factor (VEGF) is one of the most important endothelial cell mitogen which plays a critical role in normal physiological and tumor angiogenesis. OBJECTIVES The objective of this case-control study was to investigate the association of VEGF-2578C/A, -2549 I/D, and -460T/C promoter polymorphisms with esophageal cancer risk in North-West Indians. METHODS In this study, 200 sporadic esophageal cancer patients and 200 healthy, unrelated, age and gender matched controls were analyzed. The genomic DNA was extracted from blood samples using phenol chloroform method. Genotyping of VEGF- 2549I/D polymorphism was carried out by direct polymerase chain reaction (PCR) whereas VEGF -2578C/A and VEGF-460T/C) polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. RESULTS AA genotype (p = 0.005) and A allele (p = 0.005) VEGF -2578 C/A, II genotype (p = 0.011) and I allele (p = 0.012) of VEGF - 2549 I/D and CC genotype (p = 0.013) and C allele of VEGF-460T/C polymorphisms were significantly associated with increased risk of esophageal cancer. Stratification of data on the basis of gender showed that VEGF -2578 AA genotype (p = 0.001) and A allele (p = 0.001); VEGF -2549 II genotype (p = 0.002) and I allele (p = 0.002) and VEGF- 460CC genotype (p = 0.001) and C allele (p = 0.002) was significantly associated with increased risk of esophageal cancer in female group. Haplotype analysis revealed that A-2578 I- 2549 C- 460 haplotype was significantly associated with increased risk for esophageal cancer in total samples (p = 0.008) as well as in female group (p = 0.001). CONCLUSIONS The results of present study indicate that VEGF -2578C/A, - 2549I/D and -460T/C polymorphisms were significantly associated with increased risk of esophageal cancer in North-West Indians.

A microRNA binding site polymorphism in the 3' UTR region of VEGF-A gene modifies colorectal cancer risk based on ethnicity: a meta-analysis. J Egypt Natl Canc Inst 2022; 34:18. [PMID: 35462603 DOI: 10.1186/s43046-022-00118-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 03/12/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Vascular endothelial growth factor A (VEGF-A) plays an integral role in angiogenesis by contributing to growth, development, and metastasis of solid tumors. Recently, a single-nucleotide polymorphism +936C/T located in the VEGF-A 3' untranslated region (UTR) facilitated the susceptibility of colorectal cancer. The association between VEGF-A gene polymorphism +936C/T and colorectal cancer risk has been widely studied in the last decade, but presently, the results furnished remain enigmatic. Hence, the study aimed to investigate the association between VEGF-A +936C/T miRNA binding site polymorphism and the risk of developing colorectal cancer. METHODS This meta-analysis included 13 published case-control studies covering 3465 cases (colorectal cancer) and 3476 healthy controls. Publication bias was examined by means of Begg's funnel plots and Egger's regression tests. The quality of the studies included was evaluated using Newcastle-Ottawa scale. Subgroup analyses were performed in accordance to the various ethnicities of the study subjects and the study quality. RESULTS From the data obtained, it is implied that VEGF-A +936C/T polymorphism did not correlate with elevated colorectal cancer risk in all genetic models. But the results acquired from the subgroup analysis in over dominant model (CT vs. CC + TT: OR = 1.5047, 95% CI = 1.19-1.90) suggest that VEGF-A +936C/T polymorphism leads to the raise in the risk of developing CRC among the East Asian population. No association was observed in Caucasian and South Asian population. CONCLUSIONS Our results indicate that VEGF-A +936C/T polymorphism is not a risk factor for developing CRC in Caucasian and South Asian population. However, the East Asian population was related to an increased risk of developing colorectal cancer due to the presence of the minor allele.

Abstract
BACKGROUND While genome-wide association studies (GWAS) have identified germline variants influencing the risk of developing colorectal cancer (CRC), there has been limited examination of the possible role of inherited variation as a determinant of patient outcome. PATIENTS AND METHODS We performed a GWAS for overall survival (OS) in 1926 patients with advanced CRC from the COIN and COIN-B clinical trials. For single nucleotide polymorphisms (SNPs) showing an association with OS (P < 1.0 × 10-5), we conducted sensitivity analyses based on the time from diagnosis to death and sought independent replications in 5675 patients from the Study of Colorectal Cancer in Scotland (SOCCS) and 16,964 patients from the International Survival Analysis in Colorectal cancer Consortium (ISACC). We analysed the Human Protein Atlas to determine if ERBB4 expression was associated with survival in 438 patients with colon adenocarcinomas. RESULTS The most significant SNP associated with OS was rs79612564 in ERBB4 (hazard ratio [HR] = 1.24, 95% confidence interval [CI] = 1.16-1.32, P = 1.9 × 10-7). SNPs at 17 loci had suggestive associations for OS and all had similar effects on the time from diagnosis to death. No lead SNPs were independently replicated in the meta-analysis of all patients from SOCCS and ISACC. However, rs79612564 was significant in stage-IV patients from SOCCS (P = 2.1 × 10-2) but not ISACC (P = 0.89) and SOCCS combined with COIN and COIN-B attained genome-wide significance (P = 1.7 × 10-8). Patients with high ERBB4 expression in their colon adenocarcinomas had worse survival (HR = 1.50, 95% CI = 1.1-1.9, P = 4.6 × 10-2). CONCLUSIONS Genetic and expression data support a potential role for rs79612564 in the receptor tyrosine kinase ERBB4 as a predictive biomarker of survival.

Abstract
Vascular endothelial growth factor (VEGF) is one of the most important regulators of angiogenesis. Several single nucleotide polymorphisms (SNPs) are associated with the VEGF overexpression and tumor progression in several cancers. This study aimed to determine the association of VEGF rs833061 and rs2010963 polymorphism and their haplotypes with susceptibility to colorectal cancer (CRC) in the Iranian population. A total of 284 colorectal cancer patients (37.3% women, 62.7% men) were enrolled in this study. Healthy controls without evidence of cancer history or family cancer predispositions were frequency-matched to the cases by sex and age (± 5 years). Genotyping was performed by the Sequenom mass ARRAY method and the genotype distribution and risk estimate were analyzed by SPSS software. The correlation between the genotypes and clinicopathological parameters (Dukes stage, phenotype, location, differentiation, and tumor size) among colorectal cancer patients were investigated. We found a significant relationship, between rs833061T/C genotype and their TG haplotype with the age of diagnosis < 60; (p = 0.012, p = 0.014) and rs2010963G/C genotype with female gender and TG haplotype with third and fourth tumor stage and tumor location (p = 0.04and p = 0.047). This study showed that rs833061T/C genotype and TG haplotype increase the susceptibility to colon cancer in the Iranian population. This susceptibility has a significant relationship with the age of diagnosis and different stages of the tumor.

Abstract
OBJECTIVES Vascular endothelial growth factor is an endothelial-specific growth factor that promotes endothelial cell proliferation, differentiation, and survival; mediates endothelium-dependent vasodilatation; induces microvascular hyperpermeability; and participates in interstitial matrix remodeling. The aim of the present study was to investigate the association between +405 G/C polymorphism of vascular endothelial growth factor and the risk of liver rejection in liver transplant recipients. MATERIALS AND METHODS The present study included 124 patients with liver disease that led to liver transplant. There were 22 patients who experienced histologically proven acute liver rejection, and the other 102 patients showed no rejection. Both groups were matched for sex and age. The VEGF+405 G/C polymorphism was evaluated by the polymerase chain reaction-restriction fragment-length polymorphism method. RESULTS Our analyses showed no significant relationships between genotypes and alleles of +405 G/C and risk of acute liver transplant rejection. CONCLUSIONS Our report indicated that there was no association between the carrier states of +405 G/C gene polymorphism of vascular endothelial growth factor and acute rejection or nonrejection of liver transplant.

Abstract
PURPOSE Previous published data showed an impact of single-nucleotide polymorphisms in the VEGF A and VEGFR2 genes on the survival of patients with various malignancies, among others diffuse large B-cell lymphoma (DLBCL). PATIENTS AND METHODS We investigated the role of four VEGF-A and two VEGFR-2 gene polymorphisms on the outcome of 273 patients with diffuse large B-cell lymphoma who were treated with R-CHOP within a prospective, randomized trial of the German High-Grade Non-Hodgkin Lymphoma Study Group (DSHNHL). The genomic DNA samples were analyzed using commercial DNA Probes (Applied Biosystems, USA) to detect single-nucleotide polymorphisms in the VEGF A rs699947, rs1570360, rs2010963, rs3025039 and rs1870377, and rs2305948 in the VEGFR2 receptor. Hundred healthy blood donors served as a control. RESULTS There was no difference between the SNP allele frequencies in lymphoma patients compared to the control group for all investigated SNPs. None of the investigated SNPs was significantly associated with EFS or OS. After adjusting for the International Prognostic Index risk factors in a multivariate analysis, these results could be confirmed. CONCLUSION Single-nucleotide polymorphisms of the VEGF and VEGFR2 were not associated with a worse outcome in Caucasian patients with DLBCL.

Abstract
Angiogenesis, induced by the vascular endothelial growth factor A through its ligation to the vascular endothelial growth receptor 2, has been described as a crucial point in high-grade glioma development. The aim of this study was to evaluate the influence of VEGFA–2578C/A, −2489C/T, −1154G/A, −634G/C, and −460C/T, and KDR–604T/C, −271G/A, +1192G/A, and +1719A/T single-nucleotide polymorphisms on risk and clinicopathological aspects of high-grade glioma. This case–control study enrolled 205 high-grade glioma patients and 205 controls. Individuals with VEGFA–2578 CC or CA, VEGFA–1154 GG, VEGFA–634 GC or CC, and VEGFA–460 CT or TT genotypes were under 2.56, 1.53, 1.54, and 1.84 increased risks of high-grade glioma, compared to others, respectively. And 1.61, 2.66, 2.52, 2.53, and 2.02 increased risks of high-grade glioma were seen in individuals with VEGFA–2578 CC plus VEGFA–1154 GG, VEGFA–2578 CC or CA plus VEGFA–634 GC or CC, VEGFA–2578 CC or CA plus VEGFA–460 CT or TT, VEGFA–1154 GG or GA plus VEGFA–634 GC or CC, and VEGFA 634 GC or CC plus VEGFA–460 CT or TT combined genotypes, respectively, when compared to others. The “CAGT” haplotype of KDR single-nucleotide polymorphisms was more common in patients with grade IV than in those with grade III tumors, and individuals carrying this haplotype were at 1.76 increased risk of developing grade IV tumors than others. We present, for the first time, preliminary evidence that VEGFA–2578C/A and VEGFA–1154G/A single-nucleotide polymorphisms increases high-grade glioma risk, and “CAGT” haplotype of the KDR gene alters high-grade glioma aggressiveness and risk of grade IV tumors in Brazil.

Abstract
The 5-year survival probability for patients with metastatic colorectal cancer has not drastically changed over the last several years, nor has the backbone chemotherapy in first-line disease. Nevertheless, newer targeted therapies and immunotherapies have been approved primarily in the refractory setting, which appears to benefit a small proportion of patients. Until recently, rat sarcoma (RAS) mutations remained the only genomic biomarker to assist with therapy selection in metastatic colorectal cancer. Next generation sequencing has unveiled many more potentially powerful predictive genomic markers of therapy response. Importantly, there are also clinical and physiologic predictive or prognostic biomarkers, such as tumor sidedness. Variations in germline pharmacogenomic biomarkers have demonstrated usefulness in determining response or risk of toxicity, which can be critical in defining dose intensity. This review outlines such biomarkers and summarizes their clinical implications on the treatment of colorectal cancer. It is critical that clinicians understand which biomarkers are clinically validated for use in practice and how to act on such test results.

Abstract
BACKGROUND We conducted a genome-wide scan to identify non-synonymous SNPs (nsSNPs) that might influence survival after a diagnosis of colorectal cancer (CRC). METHODS We genotyped 7679 nsSNPs in 1939 Scottish patients from the Scottish Colorectal Cancer Study recruited soon after a CRC diagnosis and prospectively followed for survival outcomes. All-cause and CRC-specific survival analyses were conducted using Cox proportional hazard models adjusted for stage, age and sex for all cancer cases, after cancer type stratification and assuming additive and recessive models of inheritance. For all the SNPs that had a p-value < 0.10 a meta-analysis was performed combining the results of the discovery set and a replication set of 899 Scottish CRC patients. The p-value threshold of significance was set as at p < 10-8. RESULTS 897 and 894 nsSNPs were associated with all-cause and CRC-specific mortality, respectively, at a p-value level < 0.10 in the discovery set. Meta-analysis of the results from the discovery and replication sets was performed overall and for cancers of colon and rectum separately and none of the variants reached a p-value < 10-8. CONCLUSIONS This large scale well-powered analysis demonstrates that common nsSNPs are not associated with CRC prognosis overall.

Abstract
BACKGROUND/AIM Accumulated data suggested that Vascular Endothelial Growth Factor is a major mediator in vasculogenesis, angiogenesis and recently in tumorigenesis. Therefore, we aimed to investigate for the first time the association between VEGF gene variants (-2549I/D (rs35569394), -2578C/A (rs699947), and +936C/T (rs3025039)) with urothelial bladder cancer (UBC) in Tunisian population. METHODS A total of 218 UBC patients and 204 controls were recruited and genotyped by Polymerase Chain Reaction technique. Odds ratios (OR) and 95% confidence intervals (CIs) were used to access the association between the VEGFA gene polymorphisms and UBC. RESULTS We found a significant decreased risk association of -2578 C/A polymorphism with UBC (OR (95% CI), 0.62 (0.41-0.94), P = .026) for CA genotype and (OR (95% CI), 0.40 (0.21-0.76), P = .005) for double homozygous mutant genotype. No associations were found in case of both polymorphic sites of VEGF, vis. -2549I/D and +936C/T, respectively. Haplotype analysis revealed a strong linkage disequilibrium between -2578C/A and -2549I/D and CIC combination is the significant haplotype associated with increased risk of UBC (OR (95% CI), 3.63 (1.47-8.97), P = .005). Regarding tumor grade/stage and family history of cancer, no associations were found for -2578C/A polymorphism. CONCLUSION CIC haplotype of VEGF gene may be important risk factor for UBC development in Tunisia.

Abstract
The association between vascular endothelial growth factor (VEGF) +936 C/T gene polymorphisms and gastric cancer risk is still controversial and ambiguous. The objective of our study was to investigate this association. The Medline and Embase databases were searched by two investigators. Crude odds ratios (OR) and 95% confidence intervals (CI) were used to test the association between VEGF +936 C/T polymorphisms and gastric cancer risk. Our meta-analysis comprised seven case-control studies, which included 1,893 gastric cancer cases and 2,245 controls. The combined results showed that there was no relationship between VEGF +936 C/T gene polymorphisms and gastric cancer risk (cc: OR 0.97, 95% CI 0.85, 1.11; CT: OR 1.01, 95% CI 0.88, 1.16; TT: OR 1.10, 95% CI 0.79, 1.55). Subgroup analysis by ethnicity and stage, location, and Lauren classification of gastric cancer did not change the results. This meta-analysis suggests that there is no association between VEGF +936 C/T polymorphisms and gastric cancer risk. Further studies should pay attention to other potentially functional SNPs.

Abstract
Vascular endothelial growth factor (VEGF) and its receptor kinase insert domain-containing receptor (KDR) pathway trigger the process of angiogenesis as well as inflammation, which contributes to the development and progression of demyelinating lesions in multiple sclerosis. This work is a case-control study comprising of a total of 400 subjects with multiple sclerosis and 400 healthy controls. Participants were subjected to neurological examination and peripheral blood sampling for genotyping. Polymorphisms in the VEGF and KDR genes were assessed using the restriction fragment length polymorphism (RFLP-PCR) method. A significantly higher frequency of the T allele and TT genotype of the VEGF 936C > T (rs3025039) polymorphism was found in the multiple sclerosis group than in the healthy control group (P = 0.01 [OR = 1.41] and P = 0.01 [OR = 3.12], respectively). In addition, VEGF 936C > T showed an association with patients in a recessive model. However, the KDR -604T > C (rs2071559) polymorphism showed no significant difference in either allelic or genotype frequency between the two groups. Taken together, the results of the present study suggests that the T allele of the rs3025039 in VEGF gene could be considered a risk factor for developing multiple sclerosis in the Iranian population.

PLoS One 2017; 12:e0172709.

Abstract
Vascular endothelial growth factor (VEGF) plays critical roles in angiogenesis and vasculogenesis, which are associated with post-stroke functional recovery. However, the effects of the VEGFA polymorphisms on the outcome of ischemic stroke (IS) have been rarely reported. We therefore investigated the associations of +936C/T variant (rs3025039) with the susceptibilities and the 90-day outcomes from 494 IS patients and 337 healthy controls in Chinese population through the establishment of logistic multivariate regression model. Stroke severity at admission and outcome of 90 days were respectively assessed according to the National Institutes of Health Stroke Scale and the modified Rankin Scale. The analysis showed that there were no significant associations of the rs3025039 genotypes with the susceptibility (P = 0.229) and the severity (P = 0.734). However, when we divided the 308 IS patients into two groups according to the different outcomes, we found that the rs3025039 TC+TT genotype significantly increased the risk of poor recovery [adjusted odds ratio (OR), 1.99; 95% confidence interval (CI), 1.18–3.37]. Interestingly, we observed another 3ˈUTR variant, +1451C/T (rs3025040), exhibited strong linkage disequilibrium (r2 = 1.0) with +936C/T and was located in a predicted microRNA-binding site. The rs3025040 T allele significantly decreased the luciferase activities in four cell lines, which indicated a potential disruption of the miRNA-mRNA interaction that would result in lower VEGF expression levels. Our data suggested that the +936C/T variants significantly increased the risk of poorer stroke outcome by affecting the bindings of miR-199a and miR-199b to VEGF mRNA at the rs30250340 polymorphic site.

Abstract
AIM To investigate the associations of the genetic polymorphisms of vascular endothelial growth factor A (VEGF-A) -1498C>T and -634G>C, with the survival of patients with colorectal cancer (CRC).
METHODS A prospective cohort consisting of 131 Brazilians patients consecutively operated on with a curative intention as a result of sporadic colorectal carcinoma was studied. DNA was extracted from peripheral blood and its amplification and allelic discrimination for each genetic polymorphism was performed using the technique of polymerase chain reaction (PCR) in real-time. The real-time PCR technique was used to identify the VEGF-A -1498C>T (rs833031) and -634G>C (rs2010963) polymorphisms. Genotyping was validated for VEGF-A -1498C>T polymorphism in 129 patients and for VEGF-A -634G>C polymorphism in 118 patients. The analysis of association between categorical variables was performed using logistic regression, survival by Kaplan-Meier method and multivariate analysis by the Cox regression method.
RESULTS In the univariate analysis there was a significant association (OR = 0.32; P = 0.048) between genotype CC of the VEGF-A -1498C>T polymorphism and the presence of CRC liver metastasis. There was no association between VEGF-A -1498C>T polymorphism and VEGF-A -634G>C polymorphism with further clinical or anatomopathologic variables. The genotype CC of the VEGF-A -1498C>T polymorphism was significantly correlated with the 5-year survival (P = 0.032), but not significant difference (P = 0.27) was obtained with the VEGF-A -634G>C polymorphism with the 5-year survival in the univariate analysis. The genotype CT (HR = 2.79) and CC (HR = 4.67) of the polymorphism VEGF-A -1498C>T and the genotype CC (HR = 3.76) of the polymorphism VEGF-A -634C>G acted as an independent prognostic factor for the risk of death in CRC patients.
CONCLUSION The CT and CC genotypes of the VEGF-A -1498C>T and the CC genotype of the VEGF-A -634C>G polymorphisms are prognostic factors of survival in Brazilians patients with sporadic colorectal carcinoma.

Abstract
Tumor growth, dissemination and metastasis are dependent on angiogenesis. The predominant vascular endothelial growth factor (VEGF) isoform that plays a major role in angiogenesis is VEGF-A. Indeed, VEGF-A is implicated in promoting angiogenesis of numerous solid malignancies, including colorectal cancer (CRC). A large body of preclinical and clinical evidence indicates that the expression of specific VEGF-A isoforms represents a predominant pro-angiogenic factor, which is associated with formation of metastases and poor prognosis in CRC patients. Different isoforms of human VEGF-A have been identified, all of which arise from alternative splicing of the primary transcript of a single gene. Notably, it has been recently demonstrated that expression of type 3 isoform pattern is significantly correlated with venous involvement in CRC as well as in progression to metastatic colorectal cancer (mCRC), although it remains unclear what proportion of CRC tumors express these isoforms. This review highlights the importance of investigating the genetic and the epigenetic variations in VEGF-A pathways in CRC, the functions of different VEGF-A isoforms and their potential application as prognostic markers and/or therapeutic targets. Better understanding of the mechanisms controlling angiogenesis in liver metastases is necessary to address the limitations of current anti-angiogenic therapies.

Abstract
INTRODUCTION Vascular endothelial growth factor A (VEGFA) and its kinase insert domain receptor (VEGFR2/KDR) were reported to be upregulated in chronic myeloid leukemia (CML); however, the influence of polymorphisms in VEGFA and VEGFR2 in CML pathogenesis and therapeutic response, have not yet been elucidated. METHODS We aimed to analyze these polymorphisms in 212 CML patients and 212 healthy controls by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) approach. RESULTS The VEGFA+936C>T polymorphism did not differ significantly between the CML patients and controls. The frequency of CT genotype was higher in CML patients than in controls (25 vs. 18%), higher in males than in females (29 vs. 18%), was more prevalent in the patients with splenomegaly (p = 0.03), and was negatively associated with lactate dehydrogenase (LDH) levels (p = 0.01). The frequency of VEGFR2 mutant T-allele was higher in CML patients than controls (p < 0.0001). In the dominant model, patients having the combined AT and TT genotypes were associated with 2.6-fold higher risk of CML [odds ratio (OR) = 2.6, 95% confidence interval (CI) = 1.71–3.97, p < 0.0001]. VEGFR2 AT genotype was significantly associated with high blast count (p = 0.006), minor hematological response (p = 0.03) and poor cytogenetic response (p = 0.003), indicating its role in therapeutic resistance. In contrast, poor molecular response was observed in patients with TT genotype (p = 0.02). VEGFA+936C>T polymorphism was found to have synergistic interaction with VEGFR2+1416A>T in inflating the risk for CML further (P(interaction) = 0.0002). CONCLUSION Our results indicate that VEGFR2+1416A>T polymorphism may be a useful marker in assessing the disease progression in CML patients. In addition, VEGFA+936C>T was observed to have additive effect in inflating the risk further.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies worldwide. The majority of patients are not suitable for surgery due to the presence of metastatic disease at the time of diagnosis, which has led to a high mortality rate for patients with CRC. Lymphangiogenesis, formation of new lymphatic vessels, plays an critical role in cancer progression particularly in cancer metastasis. Vascular endothelial growth factor-C (VEGF-C) has been previously demonstrated to play a pivotal role in cancer metastasis and therefore has become an attractive target for anticancer treatments. Pien Tze Huang (PZH) is a well-known traditional Chinese formula, which has exhibited significant therapeutic effects against CRC. However, the molecular mechanisms underlying its anticancer effects, particularly in regards to antimetastasis activity, still require further elucidation. In the present study, we evaluated the effects of PZH on cell migration and VEGF-C expression using various human CRC cell lines. Moreover, using a VEGF‑C-stimulated human lymphatic endothelial cell (HLEC) model, we demonstrated that PZH suppresses lymphangiogenesis by attenuating cell migration and tube formation. This indicates that PZH possesses significant antimetastatic activity. Moreover, suppression of lymphangiogenesis by PZH via the downregulation of VEGF-C may be a potential molecular mechanism by which PZH inhibits metastasis in CRC.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (cSCC) is the second most common type of non-melanoma skin cancer (NMSC) globally. The aims of this study were to further systematically clarify the potential association of rs833061 (-460 C>T) and rs1570360 (-1154 G>A), two SNPs of VEGF, with the risk of cSCC and the prognostic impacts on cSCC patients. MATERIAL AND METHODS This hospital-based case-control study analyzed peripheral venous blood collected from 100 cSCC patients and 124 healthy controls, and gathered personal information on patients. Genotypes of the VEGF gene -460C>T and -1154G>A polymorphism were detected using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. Different distributions of allele frequencies and genotype in the case and control group were measured, comparing different genotype differences in the survival of patients with cSCC. RESULTS Distributions of allele frequencies and genotype of -460 C>T in the case and control group were statistically different; the TT + CT genotype was significantly correlated with a decrease risk of cSCC (OR=0.36, 95% CI=0.21-0.63, P<0.001). There was no difference in the distribution of allele frequencies and genotype of -1154 G>A between control and case groups. For -1154460C>T, the CC genotype was an adverse factor, associated with a significant decrease in the survival status of cSCC patients (P<0.001). For VEGF-1154 G>A, the AA genotype was significantly correlated with the reduced overall survival in cSCC patients, with the mean survival time of 23.88 months (P=0.009). CONCLUSIONS The VEGF gene -460 C>T polymorphism and -1154 G>A polymorphism may serve as potential genetic markers for the risk and prognosis of cSCC.

Abstract
Vascular endothelial growth factors (VEGFs) are the key regulators in angiogenesis and have been shown to play a significant role in the progression and prognosis of angiogenesis-related diseases, such as cancer. VEGF inhibitors are a current pharmacological tumoral strategy. However, despite the strong association between aging and cancer incidence and progression, recent findings suggest impaired angiogenesis accompanied by a reduced expression of VEGF in cells derived from aging subjects. Specific variations of VEGF genes have been demonstrated to be genetic determinants for susceptibility, outcome and therapy response, especially for the solid tumors. Considering the complications present in frail elderly patients, analysis of VEGF genetic polymorphisms in these subjects may further help in tailoring an angiogenic pharmacological strategy, and in improving our ability to better understand prognosis during therapy-related to cancer.

Abstract
PURPOSE Genome-wide association studies have identified numerous loci associated with colorectal cancer risk. Several of these have also been associated with patient survival, although none have been validated. Here, we used large independent training and validation cohorts to identify robust prognostic biomarkers for colorectal cancer. EXPERIMENTAL DESIGN In our training phase, we analyzed 20 colorectal cancer-risk SNPs from 14 genome-wide associated loci, for their effects on survival in 2,083 patients with advanced colorectal cancer. A Cox survival model was used, stratified for treatment, adjusted for known prognostic factors, and corrected for multiple testing. Three SNPs were subsequently analyzed in an independent validation cohort of 5,552 colorectal cancer patients. A validated SNP was analyzed by disease stage and response to treatment. RESULTS Three variants associated with survival in the training phase; however, only rs9929218 at 16q22 (intron 2 of CDH1, encoding E-cadherin) was significant in the validation phase. Patients homozygous for the minor allele (AA genotype) had worse survival (training phase HR, 1.43; 95% confidence intervals; CI, 1.20-1.71, P = 5.8 × 10(-5); validation phase HR, 1.18; 95% CI, 1.01-1.37, P = 3.2 × 10(-2); combined HR, 1.28; 95% CI, 1.14-1.43, P = 2.2 × 10(-5)). This effect was independent of known prognostic factors, and was significant amongst patients with stage IV disease (P = 2.7 × 10(-5)). rs9929218 was also associated with poor response to chemotherapy (P = 3.9 × 10(-4)). CONCLUSIONS We demonstrate the potential of common inherited genetic variants to inform patient outcome and show that rs9929218 identifies approximately 8% of colorectal cancer patients with poor prognosis. rs9929218 may affect CDH1 expression and E-cadherin plays a role in epithelial-to-mesenchymal transition providing a mechanism underlying its prognostic potential.

Abstract
OBJECTIVES The aim of this study was to evaluate the clinical relevance of vascular endothelial growth factor (VEGF) single nucleotide polymorphisms (SNPs) in intraductal papillary mucinous neoplasms (IPMNs). METHODS A total of 169 IPMN and 108 pancreatic ductal adenocarcinoma patients who underwent curative resection were enrolled, and VEGF +405G/C and -460C/T SNPs were investigated. RESULTS Vascular endothelial growth factor +405C/C was found more frequently in malignant IPMNs compared with +405G/G (odds ratio [OR], 2.7; P = 0.04), and +405C allele was associated with malignant IPMNs compared with +405G (P = 0.055). In branch duct IPMNs, VEGF +405C/C was significantly associated with malignant transformation (CC vs GG: OR, 4.0; P = 0.03; CC vs CG + GG: OR, 3.3; P = 0.04), and there was a trend of VEGF +405C/C associated with malignant transformation of gastric-type IPMNs (CC vs GG: OR, 3.0; P = 0.07). When the survival outcomes were analyzed based on VEGF +405G/C SNPs, however, there was no relationship between VEGF SNPs and overall survival in patients with both IPMNs and pancreatic ductal adenocarcinomas. CONCLUSIONS Vascular endothelial growth factor +405G/C SNP was significantly associated with malignant transformation in IPMNs, especially branch duct and gastric-type IPMNs. Vascular endothelial growth factor +405G/C SNP might be helpful in predicting clinical course in pancreatic disease with potential for malignant transformation.

Abstract
PURPOSE To characterize the population pharmacokinetics of bevacizumab, its binding properties to VEGF165 and the effect of demographic data and VEGF-A polymorphisms on the interplay between bevacizumab serum pharmacokinetics and VEGF165 serum concentrations in patients with colorectal cancer stage IV. METHODS Bevacizumab and VEGF165 data were collected from 19 adult patients with metastatic colorectal cancer enrolled in an observational clinical study. Bevacizumab was administered with one of the following combinations: 5-FU/Leucovorin/Irinotecan, 5-FU/Leucovorin/Oxaliplatin, Capecitabine/Irinotecan at doses ranging from 5 to 10 mg/kg every 2 or 3 weeks. Data analysis was performed using nonlinear mixed-effects modeling implemented in NONMEM 7.3. RESULTS A target-mediated drug disposition model adequately described bevacizumab concentration changes over time and its binding characteristics to VEGF165. The estimated clearance of bevacizumab was 0.18 L/day, the free VEGF165 levels at baseline were 212 ng/L, and the elimination rate constant of free VEGF165 was 0.401 day(-1). Body weight was allometrically included in all PK parameters. CONCLUSION The final model adequately described the pre- and post-dose concentrations of total bevacizumab and free VEGF165 in patients with colorectal cancer. Model parameters were consistent with those previously reported for patients with solid tumors. Correlations between the binding affinity of bevacizumab and the VEGF-2578C/A and VEGF-634G/C polymorphisms were noticed.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF-A) is a key regulator of tumor-induced angiogenesis and essential for tumor growth and distant tumor spread. The aim of the present study was to evaluate the role of VEGF-A polymorphisms and haplotypes for metastatic progression in breast cancer patients. MATERIAL AND METHODS We performed a prospective study including 801 breast cancer patients. Occurrence of metastases was examined in regular follow-up investigations. Seven VEGF-A polymorphisms were selected and determined by 5'-nuclease assays (TaqMan). The selection of VEGF-A variants was based upon their location (promoter or UTR) as well as a minor allele frequency of at least 0.10. Haplotypes and linkage disequilibrium were determined using the Haploview program. RESULTS Within a median follow-up time of 84 months, 165 (21%) patients developed distant metastases. In univariate analysis, carriers of the CCCCC haplotype formed by five polymorphisms upstream the coding region were at decreased risk of distant metastases [hazard ratio (HR)=0.743; 95% CI 0.579-0.953; p=0.019]. Univariate analysis also revealed a decreased risk of distant metastases for postmenopausal patients carrying the -634G>C polymorphism (HR 0.704; 95% CI 0.514-0.965; p=0.029) and the CCCCC haplotype (HR=0.645; 95% CI 0.464-0.898; p=0.009). After adjustment for other co-variates, the HR for distant metastases was 0.651 (95% CI 0.447-0.948) for postmenopausal carriers of the -634G>C polymorphism (p=0.025; corrected p-value=0.262), and 0.586 (95% CI 0.393-0.873) for postmenopausal patients with the CCCCC haplotype (p=0.009, corrected p-value=0.189). CONCLUSION The results from univariate and multivariate analyses suggest an influence of VEGF-A gene variants on the development of distant metastases in breast cancer patients. However, none of the observed associations reached statistical significance after correction for the effects of multiple testing. Additional prospective and sufficiently powered studies are essential before firm conclusions about the role of VEGF-A gene variants for distant progression in breast cancer can be drawn.

A retrospective observational study of the relationship between single nucleotide polymorphisms associated with the risk of developing colorectal cancer and survival. PLoS One 2015; 10:e0117816. [PMID: 25710502 PMCID: PMC4339731 DOI: 10.1371/journal.pone.0117816] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2014] [Accepted: 12/31/2014] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND There is variability in clinical outcome for patients with apparently the same stage colorectal cancer (CRC). Single nucleotide polymorphisms (SNPs) mapping to chromosomes 1q41, 3q26.2, 6p21, 8q23.3, 8q24.21, 10p14, 11q13, 11q23.1, 12q13.13, 14q22, 14q22.2, 15q13.3, 16q22.1, 18q21.1, 19q13.11, 20p12, 20p12.3, 20q13.33 and Xp22 have robustly been shown to be associated with the risk of developing CRC. Since germline variation can also influence patient outcome the relationship between these SNPs and patient survivorship from CRC was examined. METHODS All enrolled into the National Study of Colorectal Cancer Genetics (NSCCG) were genotyped for 1q41, 3q26.2, 6p21, 8q23.3, 8q24.21, 10p14, 11q13, 11q23.1, 12q13.13, 14q22, 14q22.2, 15q13.3, 16q22.1, 18q21.1, 19q13.11, 20p12, 20p12.3, 20q13.33 and xp22 SNPs. Linking this information to the National Cancer Data Repository allowed patient genotype to be related to survival. RESULTS The linked dataset consisted of 4,327 individuals. 14q22.22 genotype defined by the SNP rs4444235 showed a significant association with overall survival. Specifically, the C allele was associated with poorer observed survival (per allele hazard ratio 1.13, 95% confidence interval 1.05-1.22, P = 0.0015). CONCLUSION The CRC susceptibility SNP rs4444235 also appears to exert an influence in modulating patient survival and warrants further evaluation as a potential prognostic marker.

Genotype Correlations With Blood Pressure and Efficacy From a Randomized Phase III Trial of Second-Line Axitinib Versus Sorafenib in Metastatic Renal Cell Carcinoma. Clin Genitourin Cancer 2015; 13:328-337.e3. [PMID: 25816720 DOI: 10.1016/j.clgc.2015.02.007] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Revised: 01/28/2015] [Accepted: 02/16/2015] [Indexed: 01/07/2023]
Abstract
BACKGROUND In the phase III axitinib second-line (AXIS) trial, axitinib significantly prolonged progression-free survival (PFS) versus sorafenib in patients with previously treated metastatic renal cell carcinoma (mRCC). Analyses of associations between germline single-nucleotide polymorphisms (SNPs) and outcomes are reported. PATIENTS AND METHODS DNA samples from blood were genotyped using TaqMan allelic discrimination. Logistic/Cox regression analyses were used to evaluate association of 15 SNPs in vascular endothelial growth factor (VEGF)-A, VEGF receptor (VEGFR)1, VEGFR2, or hypoxia-inducible factor (HIF)-1α with outcomes for blood pressure (BP; Grade ≥ 3 hypertension, diastolic BP > 90 mm Hg, and increase ≥ 15 mm Hg from baseline) and efficacy (independent review committee-assessed objective response rate and PFS, and overall survival [OS]). Multivariate analyses assessed SNPs and baseline characteristics as potential predictors of PFS and OS. RESULTS Genotype data were available for 305 (42.7%) of 714 patients; 159 received axitinib and 146 sorafenib. After Bonferroni adjustment, no SNP was associated with BP outcomes. In axitinib-treated patients, VEGF-A rs699947 (A/A vs. C/C) and rs833061 (C/C vs. T/T) were associated with longer OS (27.0 vs. 13.4 months; hazard ratio [HR], 0.39; Padjusted = .015). In sorafenib-treated patients, VEGFR2 rs2071559 (G/G vs. A/A) was associated with longer OS (26.8 vs. 13.8 months; HR, 0.41; Padjusted = .030). In multivariate analyses, no SNP predicted axitinib efficacy; VEGFR2 rs2071559 predicted PFS (P = .0053) and OS (P = .0027) for sorafenib. Sensitivity/specificity of VEGFR2 rs2071559 for OS was < 80%. CONCLUSION No SNP predicted axitinib outcomes. Although VEGFR2 rs2071559 predicted sorafenib efficacy in patients with mRCC, sensitivity/specificity limitations preclude its use for selecting individual patients for sorafenib treatment.

Abstract
Background One of the main glycoproteins responsible for angiogenesis is the vascular endothelial growth factor. It is believed that C936T polymorphism, located in the VEGF gene, is correlated with susceptibility towards development of sporadic colorectal adenocarcinoma. The aim of this study was to identify the frequencies of the genotypes of C936T polymorphism of the VEGF gene in patients with sporadic colorectal adenocarcinoma, in comparison with controls, and whether this correlates with the degree of tumor invasion, lymph node involvement and occurrence of metastases at the time of the diagnosis. The analysis was done on 261 patients with sporadic colorectal adenocarcinoma and 261 controls. The genotypes of C936T polymorphism were evaluated by means of the polymerase chain reaction and enzyme digestion, using peripheral blood samples. Results The occurrences of genotype 936CC were similar in the two groups (80.5% versus 78.5%, p = 0.2288). In relation to tumor location, lymph node involvement, infiltration and tumor metastasis, no statistically significant results were obtained (p = 0.3116, p = 0.8485, p = 0.9408 and p = 0.2861, respectively). Conclusion C936T polymorphism of the VEGF gene did not influence the occurrence of sporadic colorectal adenocarcinoma development and did not correlated with the degree of tumor invasion, lymph node involvement and occurrence of metastases.

Abstract
OBJECTIVE The aim of this study was to evaluate the association between the efficacy of first-line cytotoxic chemotherapy plus bevacizumab and single-nucleotide polymorphisms (SNPs) of angiogenic genes in patients with advanced colorectal cancer (CRC). METHODS DNA was extracted from blood samples of 125 patients, and 12 SNPs were evaluated for association with the objective response rate (ORR), progression-free survival (PFS), and overall survival (OS). RESULTS The vascular endothelial growth factor A (VEGFA) rs833061 T/T was associated with superior ORR compared to its alternative genotypes (75.9 vs. 50.8%; p = 0.008), and the interleukin 8 rs4073 A/A genotype tended to be associated with poor ORR (45.0 vs. 66.0%; p = 0.067). The median PFS and OS were superior in patients with the fms-related tyrosine kinase 1 (FLT1) rs9513070 A/A genotype (8.7 vs. 6.6 months; p = 0.001 and 26.4 vs. 16.1 months; p = 0.038, respectively). The kinase insert domain receptor rs1531289 G/G genotype tended to be associated with improved PFS (8.0 vs. 7.1 months; p = 0.069). In haplotype analysis, the FLT1 rs9513070/rs9554320/rs9582036 GCA haplotype was associated with inferior PFS and OS (p = 0.004 and p = 0.041, respectively). CONCLUSION The VEGFA rs833061 SNP is associated with the ORR, and the FLT1 rs9513070 SNP and FLT1 GCA haplotypes are associated with PFS and OS in advanced CRC patients treated with cytotoxic chemotherapy plus bevacizumab.

Abstract
Purpose
Sunitinib is a first-line advanced renal cell carcinoma (RCC) standard of care. In a randomized phase II trial comparing sunitinib treatment schedules, separate exploratory biomarker analyses investigated the correlations of efficacy with selected serum, germ line single-nucleotide polymorphism (SNP), or tumor markers. Methods Advanced RCC patients received first-line sunitinib 50 mg/day on the approved 4-week-on-2-week-off schedule (n = 146) or 37.5 mg/day continuous dosing (n = 146). The following correlation analyses were performed: (1) response evaluation criteria in solid tumors-defined tumor response with serum soluble protein levels via two distinct multiplex (n < 1,000) platforms; (2) response and time-to-event outcomes with germ line SNPs in vascular endothelial growth factor (VEGF)-A and VEGF receptor (VEGFR)3 genes; and (3) response and time-to-event outcomes with tumor immunohistochemistry status for hypoxia-inducible factor 1-alpha (HIF-1α) and carbonic anhydrase-IX or tumor Von Hippel–Lindau (VHL) gene inactivation status. Results Lower baseline angiopoietin-2 (Ang-2) and higher baseline matrix metalloproteinase-2 (MMP-2) levels were identified by both platforms as statistically significantly associated with tumor response. There were no significant correlations between VEGF-A or VEGFR3 SNPs and outcomes. Progression-free survival was longer for HIF-1α percent of tumor expression groups 0–2 (HIF-1α low) versus 3–4 (HIF-1α high; p = 0.034). There were no significant correlations between outcomes and each VHL inactivation mechanism [mutation (86 % of VHL-inactive patients), methylation (14 %), and large deletion (7 %)] or mechanisms combined. Conclusions Serum Ang-2 and MMP-2 and tumor HIF-1α were identified as relevant baseline biomarkers of sunitinib activity in advanced RCC, warranting further research into their prognostic versus predictive value.

Abstract
The cellular apoptosis susceptibility (CSE1L) gene has been demonstrated to regulate multiple cellular mechanisms including the mitotic spindle check point as well as proliferation and apoptosis. However, the importance of CSE1L in human colon cancer is largely unknown. In the present study, we examined expression levels of CSE1L mRNA by semiquantitative RT-PCR. A lentivirus-mediated small interfering RNA (siRNA) was used to knock down CSE1L expression in the human colon cancer cell line RKO. Changes in CSE1L target gene expression were determined by RT-PCR. Cell proliferation was examined by a high content screening assay. In vitro tumorigenesis was measured by colony-formation assay. Cell cycle distribution and apoptosis were detected by flow cytometric analysis. We found CSE1L mRNA to be expressed in human colon cancer cells. Using a lentivirus based RNAi approach, CSE1L expression was significantly inhibited in RKO cells, causing cell cycle arrest in the G2/M and S phases and a delay in cell proliferation, as well as induction of apoptosis and an inhibition of colony growth capacity. Collectively, the results suggest that silencing of CSE1L may be a potential therapeutic approach for colon cancer.

Abstract
We investigated the association of three single nucleotide polymorphisms (SNPs) in VEGF gene with the prognosis of renal cell carcinoma (RCC) and its association with clinical characteristics of RCC, such as tumor stages, metastasis, and tumor size. Polymerase chain reaction (PCR) restriction fragment length polymorphism analysis was used to genotype specimens for three polymorphisms (-2578C/A, -1154G/A, and -634G/C) in the VEGF gene. Hazard ratios (HRs) and their confidence intervals (CIs) were used to analyze the association of three SNPs in the VEGF gene with survival time using a multivariate Cox proportional hazards model. Frequencies of VEGF-2578AA genotype and A allele were significantly higher in patients with III-IV tumor stage or larger tumor size when compared with CC genotype. Moreover, frequencies of VEGF-634CC genotype and C allele were significantly higher in patients with tumor size >4 cm when compared with -634GG genotype. By Cox proportional hazards model, patients carrying VEGF-2578AA genotype and A allele significantly increased the risk of death from RCC, with the adjusted HRs (95 % CI) of 2.23 (1.15-4.36) and 1.55 (1.11-2.17), respectively. Our study suggests that VEGF-2578C/A and VEGF-634G/C polymorphisms may have effects on the prognosis of RCC. This finding might help in clarifying the mechanisms of RCC development and progression.

Abstract
SUMMARY Colorectal cancer survival has increased over the past few years, mainly due to the advances in the metastatic setting. Nonetheless, in the adjuvant scenario, minor improvements have been made, as the tumor's anatomopathological features remain to be most important factors for predicting the risk of recurrence and the prognosis. A deeper understanding of the molecular mechanisms involved in colorectal carcinogenesis, progression, invasion and metastasis development, have laid the groundwork for the search of genetic biomarkers that can help identify patients at a higher risk of recurrence. Common germline variants in genes within molecular pathways responsible for cancer development and progression have proven to influence the probability of relapse and the patient's prognosis. Here, we systematically review the relevance of genetic variants as prognostic biomarkers in colorectal carcinoma.

Abstract
BACKGROUND AND AIM Angiogenesis plays a key role in growth, progression, and metastasis of various cancers. Vascular endothelial growth factor (VEGF) polymorphism has been associated with several cancers. Role of VEGF has not been reported in gallbladder cancer (GBC). Present study was designed to investigate the role of VEGF polymorphism in GBC and in other (benign) gallbladder diseases, that is chronic cholecystitis (CC) and xanthogranulomatous cholecystitis (XGC). METHODS Blood samples were collected from 195 GBC, 140 CC, and 47 XGC patients and 300 normal healthy controls. VEGF polymorphisms were investigated using amplification refractory mutation system polymerase chain reaction for g.43737830A>G and g.3437A>C, polymerase chain reaction-restriction fragment length polymorphism for c.*237C>T, and g.43736418delTinsG amplified by polymerase chain reaction. RESULTS At g.43737830A>G, GA genotype showed susceptibility (odds ratio [OR] = 1.65 and OR = 1.68) and GG genotype showed protective association (OR = 0.58 and OR = 0.50) with GBC and CC. Allele A of VEGF g.43737830A>G was risk associated with GBC and CC (OR = 1.48 and OR = 1.70), while G allele was risk protective for GBC and CC (OR = 0.67 and OR = 0.58). At g.3437A>C, genotype CA was risk protective for GBC (OR = 0.61). TT genotype of c.*237C>T was susceptible for GBC and CC (OR = 2.59 and OR = 3.48), while CC genotype was risk protective for GBC and CC (OR = 0.61 and OR = 0.34). T allele of c.*237C>T polymorphism was risk associated with GBC and CC (OR = 1.63 and OR = 2.90), while C allele was risk protective for GBC and CC (OR = 0.38 and OR = 0.28). Haplotype I-C-A-C was risk protective for GBC (OR = 0.27). CONCLUSION The present study suggests that c.*237C>T and g.43737830A>G polymorphisms are useful markers of susceptibility to GBC.

Abstract
The use of pharmaceuticals for colon cancer treatment has been increasingly personalized, in part due to the development of new molecular tools. In this review, we discuss the old and new colon cancer chemotherapeutics, and the parameters that have been shown to be predictive of efficacy and safety of these chemotherapeutics. In addition, we discuss how alternate pharmaceuticals have been developed in light of a potential lack of response or resistance to a particular chemotherapeutic.

Abstract
Angiogenesis and cell cycle control play critical roles in breast cancer susceptibility and clinical outcome and are mainly controlled by vascular endothelial growth factor (VEGF) and cyclin-dependent kinases, respectively. Functional germline polymorphisms in these genes alter the function, thereby causing inter-individual differences in breast cancer risk and clinical outcome. In this study, we investigated the influence of the functional polymorphisms VEGF-A rs3025039 C > T and CCND1 rs9344 G > A on risk and clinical outcome in early-stage breast cancer. DNA of 539 female patients with histologically confirmed early-stage breast cancer and 804 control subjects was genotyped for these polymorphisms. Genotypes were tested for associations with breast cancer risk and clinical outcome. There was no significant association between the polymorphisms and breast cancer risk. However, the minor allele of VEGF-A rs3025039 C > T was significantly associated with decreased recurrence-free survival (HR 1.845; 95% confidence interval [CI] 1.035-3.290; P = 0.038) and remained significant in multivariate analysis (HR 1.880; 95% CI 1.020-3.465; P = 0.043). Patients carrying at least one A-allele in CCND1 rs9344 G > A showed a trend towards decreased recurrence-free survival in univariate analysis (HR 2.379; 95% CI 0.841-6.728; P = 0.068). This study provides evidence that the functional VEGF-A rs3025039 C > T polymorphism influences recurrence-free survival in early-stage breast cancer.

Abstract
AIM The vascular endothelial growth factor (VEGF) or its family might play role in tumor-related angiogenesis in gastrointestinal stromal tumors (GIST), thereby affecting the prognosis. Accordingly, the present study analyzed the impact of VEGF and VEGF receptor-2 (VEGFR-2) gene polymorphisms on the prognosis for GIST patients. METHODS In all, 213 consecutive patients with GIST from five medical centers were enrolled in the present study. The genomic DNA was extracted from paraffin-embedded tumor tissue, and four VEGF (-2578C/A, -1498C/T, -634G/C, and +936C/T) and one VEGFR-2 (+1416A/T) gene polymorphisms were determined using a Sequenom MassARRAY system. RESULTS With a median follow up of 18.4 months, the estimated 5-year relapse-free survival and overall survival rates were 70 and 87%, respectively. In a multivariate analysis including age, sex, primary site of disease, pathology and risk stratification, no significant association was observed between the polymorphism of the VEGF and VEGFR-2 genes and survival. CONCLUSION None of the five VEGF and VEGFR-2 gene polymorphisms investigated in this study was found to be an independent prognostic marker for Korean patients with surgically resected GIST. However, further studies on a larger scale are warranted to clarify the role of VEGF and VEGFR gene polymorphisms as a prognostic biomarker for GIST patients.

Abstract
Antiangiogenic therapy, especially treatment with sorafenib, is the primary treatment for patients with advanced hepatocellular carcinoma (HCC). However, the efficacy of such therapy is modest, with low objective response rates and limited prolongation of survival times. Several researchers have investigated predictive biomarkers to help identify patients who can benefit most from antiangiogenic therapy. The largest study on this topic to date was based on the pivotal phase III study of sorafenib (the SHARP study) and did not find any plasma markers that could predict the efficacy of sorafenib. Other studies based on single-arm phase II clinical trials found some potential predictive markers, such as early alpha-fetoprotein response, the serum insulin-like growth factor-1 level at baseline, and the volume transfer constants of dynamic contrast-enhanced magnetic resonance imaging. These findings require validation by further studies. Identifying predictive biomarkers of antiangiogenic therapy for HCC remains challenging and warrants further investigations.

Abstract
Angiogenesis is a universal requirement for the growth of solid tumours beyond the limits of oxygen diffusion from the existing vasculature. The expression and function of proangiogenic and antiangiogenic factors are altered in solid malignancies to drive net neoangiogenesis. Vascular endothelial growth factor (VEGF) has been confirmed in several clinical trials as an important therapeutic target in colorectal cancer (CRC) treatment. However, given that the efficacy of antiangiogenic agents appears to be limited to a subset of patients, the identification of who will obtain the greater benefit from this therapy or suffer from specific toxicities and when or for how long they should be administered in the treatment algorithm are major open questions for clinicians and challenges for present and future research. Current evidence indicates some predictive value for particular circulating measures, such as an increase in VEGF, a decrease in vascular endothelial growth factor receptor 2 (VEGFR-2) or circulating endothelial cells, tissue biomarkers, microvessel density, KRAS and BRAF gene mutations or polymorphisms affecting components of the VEGF pathway. Many questions relating to these and other surrogate biomarkers, however, remain unanswered and their clinical usefulness has yet to be proven. This review will focus on the present status of knowledge and future perspectives for developing molecular tools to foresee and monitor antiangiogenic therapy activity in CRC patients.

Abstract
Background The aim of this study is to evaluate the associations between vascular endothelial growth factor (VEGF) Single-nucleotide polymorphisms (SNPs) and clinical outcome in advanced gastric cancer patients treated with oxaliplatin, 5-fluorouracil, and leucovorin (FOLFOX). Methods Genomic DNA was isolated from whole blood, and six VEGF (−2578C/A, -2489C/T, -1498 T/C, -634 G/C, +936C/T, and +1612 G/A) gene polymorphisms were analyzed by PCR. Levels of serum VEGF were measured using enzyme-linked immunoassays. Results Patients with G/G genotype for VEGF -634 G/C gene polymorphism showed a lower response rate (22.2%) than those with G/C or C/C genotype (32.3%, 51.1%; P = 0.034). Patients with the VEGF -634 G/C polymorphism G/C + C/C genotype had a longer progression free survival (PFS) of 4.9 months, compared with the PFS of 3.5 months for those with the G/G (P = 0.043, log-rank test). By multivariate analysis, this G/G genotype of VEGF -634 G/C polymorphism was identified as an independent prognostic factor (Hazard ratio 1.497, P = 0.017). Conclusion Our data suggest that G/G genotype of VEGF -634 G/C polymorphism is related to the higher serum levels of VEGF, and poor clinical outcome in advanced gastric cancer patients.

Abstract
AIM To investigate the prognostic effect of three VEGF-A SNPs, -2578, -460 and 405, as well as the corresponding haplotype combinations, in a unique population of stage II colon cancer patients. PATIENTS & METHODS The study included all patients diagnosed with stage II colon cancer in Denmark in 2003 (698 patients). One paraffin-embedded tissue block from each patient was used for DNA extraction and analysis of the three VEGF SNPs. RESULTS The homozygous genotype VEGF -2578 AA had significant effect on time to tumor recurrence (hazard ratio [HR] = 2.01 [95% CI: 1.13-3.56]; p = 0.02) as well as -460TT (HR = 0.50 [95% CI: 0.29-0.89]; p = 0.02). Patients harboring the haplotype combinations ACG,CTC and ACG,ACG displayed a significantly shorter time to tumor recurrence in both univariate (HR = 1.87 [95% CI: 1.21-2.89]; p = 0.008) and multivariate analysis (HR = 1.76 [95% CI: 1.09-2.82]; p = 0.02). CONCLUSION We found that the gene polymorphism in VEGF-A holds prognostic information and should be considered as a potential adjunct in identification of high-risk stage II colon cancer patients.

Abstract
Dicer, an endonuclease in RNase III family, is essential for the RNA interference (RNAi) pathway. Aberrant expression of Dicer has been shown in various cancers including some subtypes of T cell lymphoma (TCL), which influences patient prognosis. A single-nucleotide polymorphism (SNP) rs3742330A>G has been identified in the Dicer gene, located in the 3′ untranslated region (3′ UTR) that is important for mRNA transcript stability. We investigated whether rs3742330 is associated with the survival in 163 TCL patients. Significant association between Dicer rs3742330 and TCL survival were found. Patients carrying the GG genotype (n = 12) had a significantly increased overall survival (OS) compared with those carrying the GA and AA genotypes (n = 70 and n = 81, respectively; p = 0.031). Moreover, the significant association was maintained for patients with mature T type (n = 134; p = 0.026). In multivariate Cox-regression analysis, rs3742330 proved to be an independent predictor for OS, together with the commonly used International Prognostic Index (IPI) and BAFF rs9514828, another SNP we have previously reported to be associated with TCL survival, with hazard ratios (HRs) for patient death rate of 8.956 (95% CI, 1.210 to 66.318; p = 0.032) for the GA genotype and 10.145 (95% CI, 1.371 to 75.084; p = 0.023) for the AA genotype. Furthermore, we observed cumulative effects of Dicer rs3742330 and BAFF rs9514828 on TCL survival. Compared with patients carrying zero unfavorable genotype, those carrying one and two unfavorable genotypes had an increased risk of death with a HR of 7.104 (95% CI, 0.969–53.086; p = 0.054) and 14.932 (95% CI, 1.950–114.354; p = 0.009), respectively, with a significant dose-response trend (ptrend = 0.004). In conclusion, Dicer rs3742330 is associated with TCL survival, suggesting that genetic variation might play a role in predicting prognosis of TCL patients.

Abstract
BACKGROUND Angiogenesis plays an important role in tumor development, progression, and metastasis. Vascular endothelial growth factor (VEGF) is a key regulator of angiogenesis. However, the contribution of common VEGF polymorphisms to colorectal cancer (CRC) prognosis remains unclear. METHODS We have genotyped four polymorphisms of VEGF (-2578C>A, -1154G>A, -634G>C, and 936C>T) in 350 CRC cases from the Korean population. The genotyping of VEGF polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism assay. RESULTS Although not every VEGF polymorphism was significantly correlated with patient prognosis in overall 350 CRC patients, we found that the VEGF -2578CA genotype was associated with a significantly poor prognosis for rectal cancers compared to the CC genotype (HR = 2.156; 95 % CI 1.090-4.267; P = 0.028). In addition, we found that the -2578A/-1154G/-634G/+936C haplotype was significantly associated with a decreased overall survival (OS) rate in all 350 CRC patients (HR = 2.530; 95 % CI 1.340-4.780; P = 0.004). In combination analysis, we found that the combined VEGF -2578CA+AA/-1154GG genotype was associated with a poor OS rate in all 350 CRC patients (HR = 2.068; 95 % CI 1.159-3.693; P = 0.015). CONCLUSIONS The VEGF gene polymorphisms investigated in this study were not found to be independent prognostic markers in Korean CRC populations. However, our results suggest that the VEGF -2578C>A variant may be a potential genetic marker for rectal cancer prognosis. Further large population studies are warranted to define whether the -2578C>A polymorphism is a prognostic marker of rectal cancer.

Abstract
The systemic treatment of cancer with traditional cytotoxic chemotherapeutic agents and more targeted agents is often complicated by the onset of adverse drug reactions. Pharmacogenetic prediction of adverse drug reactions might have consequences for dosing and efficacy. This review discusses relevant examples where the germline variant-toxicity relationship has been validated as an initial step in developing clinically useful pharmacogenetic markers and provides examples where germline variants have influenced dosing strategies and/or survival or other outcomes of efficacy. This review will also provide insight into the reasons why more pharmacogenetic markers have not been routinely integrated into clinical practice.
