Abstract:
Background: Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers
(ARB) are mainly known as anti-hypertensive drugs. Recent evidence suggests their anti-tumor potential
against renal cancer. More than one-fourth of patients present with metastasis on their first visit.
Objective: The purpose of the current study was to examine the potential clinical impact of ACEI/ARB on metastatic
renal cell carcinoma (mRCC).
Methods: We searched through several online databases, including Pubmed, Scopus, Web of Science, and Embase,
to find clinical studies that have investigated the association between treatment with ACEI/ARB and the
survival of patients with mRCC. The hazard ratio (HR) and 95% confidence interval (95% CI) were utilized to
assess the strength of the association.
Results: A total of 6 studies with a total number of 2,364 patients were found eligible for the final analysis. The
HR for the relationship between ACEI/ARB use and overall survival (OS) showed patients undergoing treatment
with ACEI/ARB to have higher OS than non-users (HR: 0.664, 95% CI 0.577-0.764, p = 0.000). Furthermore,
the HR for the relationship between ACEI/ARB use and progression-free survival (PFS) showed patients
undergoing treatment with ACEI/ARB to have higher PFS than non-users (HR: 0.734, 95% CI 0.695-0.794, p =
0.000).
Conclusion: The results of this review offer ACEI/ARB as a potential therapeutic option associated with improved
survival outcomes in patients receiving anti-vascular endothelial growth factor therapy.
