Abstract:
Recently, several meta-analysis suggested an increased risk of cancers linked to the use of antagonists of angiotensin-2 receptors or inhibitors of angiotensinogen converting enzyme. The results of epidemiological studies are conflicting. Meta-analysis as well as retrospective studies are not reliable and biased, since they have never been designed to explore any pro- or antitumoral effect. We lack of prospective studies that could take off the doubt on these drugs. Nevertheless, all experimental researches pointed out potent antitumoral properties. Indeed, direct antiproliferative and neo-angiogenic inhibition have been described on tumor cell cultures as well as on animal models. Moreover, we are convinced that the use of antagonists of angiotensin-2 receptors and inhibitors of angiotensinogen converting enzyme may be then of clinical use in the near future in association with classical antitumor drugs. In this review, we proposed to explore these data by a thorough analysis of recent literature associating epidemiological and experimental studies.
Insights
Antagonists of angiotensin-2 receptors and inhibitors of angiotensinogen converting enzyme show potent anticancer properties in experimental research, despite conflicting epidemiological data. Further prospective studies are needed to clarify their clinical use in cancer treatment.
Area of Science:
- Pharmacology
- Oncology
- Cardiovascular Medicine
Context:
- Conflicting epidemiological studies suggest a potential cancer risk associated with angiotensin-2 receptor antagonists (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs).
- Existing meta-analyses and retrospective studies are limited by design, potentially introducing bias and failing to adequately assess antitumor effects.
- There is a lack of prospective studies to definitively resolve the debate surrounding the oncological impact of these widely used cardiovascular medications.
Purpose:
- To critically review and analyze recent literature on the association between ARBs and ACEIs and cancer.
- To reconcile conflicting findings from epidemiological studies with robust experimental evidence.
- To explore the potential antitumoral properties of ARBs and ACEIs.
Summary:
- Experimental research consistently demonstrates significant antitumoral effects of ARBs and ACEIs, including direct antiproliferative activity and inhibition of neo-angiogenesis in preclinical models.
- These drugs have shown potent effects on tumor cell cultures and animal models, suggesting a direct role in cancer suppression.
- Despite conflicting epidemiological data, experimental findings strongly support the potential therapeutic value of these agents in oncology.
Impact:
- The findings suggest that ARBs and ACEIs may hold future clinical utility as adjuncts to conventional chemotherapy in cancer treatment.
- This review highlights the need for well-designed prospective clinical trials to validate the anticancer potential of these drugs.
- Understanding the dual role of these cardiovascular drugs in cancer could lead to novel therapeutic strategies and improved patient outcomes.
