Prevalence of Cancer Across Cardiovascular and Cardiometabolic Conditions: A Systematic Review and Meta-Analysis
Abstract
Background: To the best of our knowledge, no previous systematic review has comprehensively quantified cancer prevalence across the broad spectrum of cardiovascular and cardiometabolic conditions included in the present study. We aimed to estimate pooled prevalence of active cancer (primary outcome) and other cancer categories among patients with coronary artery disease (CAD), heart failure (HF), atrial fibrillation (AF), hypertension, Type 2 diabetes mellitus (DM), stroke, peripheral artery disease (PAD), and valvular heart disease (VHD).
Methods: PubMed, Web of Science, and Scopus were searched from 2010 to July 2024. Secondary outcomes included prevalence of any, previous, haematological, solid, and metastatic cancer. Prevalence estimates were calculated using one-step generalized linear mixed models.
Results: A total of 676 studies comprising approximately 180 million participants were included. The primary analysis of active cancer included 59 studies (4,759,695 patients). Active cancer prevalence ranged from 4.22% (95% confidence interval [CI] 2.18-5.32) in Type 2 DM to 5.55% (95% CI 3.97-7.01) in AF. The prevalence of any cancer, a secondary outcome with more heterogeneous ascertainment, ranged from 7.04% (95% CI 6.05-8.03) in CAD to 14.10% (95% CI 12.20-15.99) in AF.
Conclusion: Cancer represents a substantial comorbidity across cardiovascular and cardiometabolic conditions. Although cancer ascertainment methods varied across studies, particularly for any cancer, the…
How strong is the evidence?
Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid. Reported size: 4,759,695 participants or records.
