Aim
To perform a systematic review and meta‐analysis of published clinical trials to determine incidence rate and overall risk of hypertension with vandetanib in cancer patients.
Methods
A comprehensive literature search for studies published up to March 2012 was performed. Summary incidence rates, relative risk (RR), and 95% confidence intervals (CI) were calculated employing fixed‐ or random‐effects models depending on the heterogeneity of the included trials.
Results
A total of 11 trials with 3154 patients were included for the meta‐analysis. The summary incidences of all‐grade and high‐grade hypertension in patients with cancer were 24.2% [95% confidence interval (CI), 18.1–30.2%] and 6.4% (95% CI, 3.3–9.5%), respectively. Subgroup analysis demonstrated that the pooled incidences of all‐grade and high‐grade hypertension were 21.8% [95% CI, 15–30.5%] and 7.6% (95% CI, 2.8–18.8%), respectively, among non‐small‐cell lung cancer (NSCLC) patients, and 32.1% (95% CI: 27.3–37.3%) and 8.8% (5.9%–12.9%), respectively, among MTC patients, and 15.4 (95% CI: 3.2–33.7%) and 3.4% (95% CI: 1%–11.1%) respectively, among non‐MTC/NSCLC tumors patients. Furthermore, vandetanib was associated with a significant increased risk of all‐grade hypertension (RR 5.1, 95% CI: 3.76–6.92, P = 0.000) and high‐grade hypertension (RR 8.06, 95% CI: 3.41–19.04, P = 0.000) in comparison with controls.
Conclusions
There is a significant risk of developing hypertension in cancer patients receiving vandetanib. Appropriate monitoring and treatment is strongly recommended to prevent cardiovascular complications.
