N2 - Recently, concerns have been raised that angiotensin II receptor blockers (ARBs) may be associated with an increased risk for cancer development. However, the relation between ARBs and cancer is still unclear. Therefore, a nationwide population-based study was conducted to investigate the possible influence of ARBs on the occurrence of new cancers in patients with hypertension by using the Taiwan National Health Insurance database. A total of 109,002 patients with newly diagnosed hypertension were identified from a cohort database of 1 million individuals from January 1, 1998, to December 31, 2006. Among them, 40,124 (36.8%) had received ARBs for hypertension. The end point was the development of any type of cancer before the end of 2007. During an average of 5.7 ± 2.6 years of follow-up, a total of 9,067 cases of new cancer occurrence were observed. The log-rank test showed that the occurrence rate of newly diagnosed cancers in the subjects receiving ARBs was significantly lower than those receiving treatment without ARBs (ARBs vs controls 3,082 vs 5,985, p <0.001). After adjusting for age, gender, co-morbidities, and medications for hypertension control, ARB use was found to be independently associated with a decreased risk for cancer occurrence (hazard ratio 0.66, 95% confidence interval 0.63 to 0.68, p <0.001). In conclusion, long-term use of ARBs is associated with a lower incidence of cancer occurrence, thereby suggesting that ARBs may prevent cancer development.
