INTRODUCTION: It is suggested that survivors of different types of cancer may have an increased risk of stroke. Our study aims to evaluate cancer patients and non-cancer controls by analyzing stroke events in each group. Previous studies concluded that certain types of cancer increased stroke risk, however, their results had significant heterogeneity and statistical concerns.
METHODS: Medline, Embase, and Cochrane databases were systematically searched until February 18th, 2024, assessing stroke in cancer survivor patients compared to the global population. Data were examined using the Mantel-Haenszel method and 95% CIs. Heterogeneity was assessed using I² statistics. Rstudio software, version 4.2.3., was used for statistical analysis.
RESULTS: A total of 18 studies were included, and stroke was reported in both cancer and non-cancer groups. Breast cancer (HR 1.09; 95% CI 1.02-1.17; p = 0.01; I²= 0%), Central Nervous System cancers (HR 2.47; 95% CI 1.01-6.01; p = 0.047; I²= 78%), cervical cancers (HR 1.58; 95% CI 1.19-2.09; p = 0.001; I²= 0%), head and neck cancers (HR 1.4439; 95% CI 1.3095-1.5922; p < 0.001; I²=31.5%), lung cancers (HR 1.60; 95% CI 1.40-1.83; p < 0.001; I²=67%), multiple myeloma (HR 1.58; 95% CI 1.32-1.89; p < 0.001; I²= 49%), nasopharyngeal cancers (HR 1.9178; 95% CI 1.3358-2.7533; p < 0.001; I²=89.7%), oesophageal cancers (HR 1.33; 95% CI 1.07-1.65; p = 0.009; I²= 0%), ovarian cancers (HR 1.33; 95% CI 1.07-1.65; p = 0.01; I²= 38%), pancreatic cancers (HR 2,70; 95% CI 2.34-3.11; p < 0.001; I²= 0%) and rectum cancers (HR 1.29; 95% CI 1.01-1.63; p = 0.04; I²= 0%) showed statistically significant differences between groups in favor of non-cancer controls.
CONCLUSIONS: In this meta-analysis, the stroke risk was increased in all cancers that reached statistical significance. Furthermore, our study brings relevant data to the body of literature concerning this long-term clinical uncertainty.
