Endothelial Growth Factor

Purpose Vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs) have become the cornerstone in the treatment of several malignancies. These drugs have also been associated with an increase in the risk of potentially life-threatening adverse events, such as arterial thrombotic events, bleeding, congestive heart failure, and others. We performed an up-to-date meta-analysis to determine the risk of fatal adverse events (FAEs) in patients with cancer treated with VEGFR TKIs. Methods MEDLINE and PubMed databases were searched for articles published from January 1966 to February 2011. Eligible studies were limited to trials of US Food and Drug Administration–approved VEGFR TKIs (pazopanib, sunitinib, and sorafenib) that reported on patients with cancer with any primary tumor type, randomized design, and adequate safety profile. Statistical analyses were conducted to calculate the summary incidence, relative risk (RR), and 95% CIs by using random-effects or fixed-effects models on the basis of the heterogeneity of included studies. Results In all, 4,679 patients from 10 randomized controlled trials (RCTs) were included, with 2,856 from sorafenib, 1,388 from sunitinib, and 435 from pazopanib trials. The incidence of FAEs related to VEGFR TKIs was 1.5% (95% CI, 0.8% to 2.4%) with an RR of 2.23 (95% CI, 1.12 to 4.44; P = .023) compared with control patients. On subgroup analysis, no difference in the rate of FAEs was found between different VEGFR TKIs or tumor types. No evidence of publication bias was observed. Conclusion In a meta-analysis of RCTs, the use of VEGFR TKIs was associated with an increased risk of FAEs compared with control patients.

Background/aimsClinical trials suggest anti-vascular endothelial growth factor is more effective than intravitreal dexamethasone as treatment for macular oedema secondary to branch retinal vein occlusion. This study asks if ‘real world’ data from a larger and more diverse population, followed for a longer period, also support this conclusion.MethodsData collected to support routine care at 27 NHS (National Health Service) Trusts between February 2002 and September 2017 contained 5661 treatment-naive patients with a single mode of treatment for macular oedema secondary to branch retinal vein occlusion and no history of cataract surgery either during or recently preceding the treatment. Number of treatment visits and change in visual acuity from baseline was plotted for three treatment groups (anti-vascular endothelial growth factor (anti-VEGF), intravitreal dexamethasone, macular laser) for up to 3 years.ResultsMean baseline visual acuity was 57.1/53.1/62.3 letters in the anti-VEGF/dexamethasone/macular laser groups, respectively. This changed to 66.72 (+9.6)/57.6 (+4.5)/63.2 (+0.9) at 12 months. Adequate numbers allowed analysis at 18 months for all groups (66.6 (+9.5)/56.1 (+3.0)/60.8 (-1.5)) and for anti-VEGF at 36 months (68.0, +10.9) Mean number of treatments were 5.1/1.5/1.2 at 12 months, 5.9/1.7/1.2 at 18 months for all three groups and 10.3 at 36 months for anti-VEGF.ConclusionsVisual acuity improvements were higher and more sustained with anti-VEGF. Higher treatment burden occurred with anti-VEGF but this reduced over 36 months. Patients with better vision at baseline than those in the clinical trials maintained high levels of vision with both anti-VEGF and dexamethasone.
