Antagonistes de l'angiotensine II et cancer: un bilan rassurant [Angiotensin II receptor blockers (ARBs) and cancer: a reassuring balance].

The effects of drugs on new cancer and cancer-related death are a major concern. Recently, a meta-analysis raised the possibility that ARBs might have an adverse impact in this respect. This point of view was highly debated until the publication of two other meta-analyses which did not demonstrate any increased risk of new cancer occurrence as well as of cancer related-death with the use of ARBs in patients with hypertension, heart failure and/or nephropathy. This illustrates that the results of meta-analyses should be interpreted cautiously and critically in order to avoid biased conclusions. Overall the bulk of evidence today indicates that ARBs are not associated with an increased cancer risk.
