OBJECTIVE
Congestive heart failure (CHF) associated with vascular endothelial growth factor tyrosine-kinase inhibitors (VEGFR-TKIs) has emerged as a relevant problem in clinical and scientific communities. We performed an up-to-date, comprehensive meta-analysis to determine the overall incidence and risk of CHF in cancer patients receiving VEGFR-TKIs.
METHODS
The databases of PubMed, Web of Science and abstracts presented at the American Society of Clinical Oncology up to August 31 2013 were searched for relevant articles. Statistical analyses were conducted to calculate the summary incidence, odds ratio (OR) and 95% confidence intervals (CIs) by using either random effects or fixed effect models according to the heterogeneity of included studies.
RESULTS
A total of 10 553 patients from 36 clinical trials were included. The overall incidence of all grade and high grade CHF associated with VEGFR-TKIs was 3.2% (95% CI 1.8%, 5.8%) and 1.4% (95% CI 0.9%, 2.3%), respectively. The use of VEGFR-TKIs significantly increased the risk of developing all grade (OR 2.37, 95% CI 1.76, 3.20, P < 0.001) and high grade (OR 3.51, 95% CI 1.74, 7.05, P < 0.001) CHF. In subgroup analyses, the risk of CHF did not significantly vary with tumour types (P = 0.071 for all grade; P = 0.72 for high grade) and VEGFR-TKIs (P = 0.55 for all grade; P = 0.99 for high grade). Meta-regression indicated that CHF might possibly occur early in the treatment of VEGFR-TKIs. No evidence of publication bias was observed.
CONCLUSIONS
The use of VEGFR-TKIs is associated with a significantly increased risk of developing congestive heart failure in cancer patients. Clinicians should be aware of this risk and provide close monitoring in patients receiving these therapies.
