The role of angiotensin II in cardiovascular disease-induced cancer growth.
Article in Cardio-oncology (London, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe higher incidence of cancer in patients with cardiovascular disease (CVD) has historically been explained by shared risk factors. Recent studies suggest, however, a causal relationship. Nevertheless, the mechanisms of CVD-induced cancer are incompletely understood. Here, we hypothesize that angiotensin II (ANGII) links CVD and increased cancer growth.
objectiveWe investigated the impact of ANGII-induced CVD on cancer growth in vivo, differentiating between a direct effect of ANGII on tumor cells or indirect effects secondary to CVD.
methodsThe effect of ANGII on cancer growth was studied in C57BL/6J mice with cancer. Cancer was either induced by subcutaneous injection of Lewis lung carcinoma (LLC) cells, MC38 colon cancer cells, or by genetic susceptibility (APC
resultsHigh dose ANGII-treatment induced left ventricle (LV) hypertrophy and cardiac fibrosis, and enhanced growth of injected tumor cells, but only when LCC tumor cells with high expression of AT1 were used, and when these cells were injected during ANGII treatment. ANGII did not increase cancer growth when LCC cells were injected after halting ANGII treatment, or when MC38 tumor cells with low AT1 levels were used. ANGII also increased the number of intestinal polyps in APC
conclusionThis study indicates that ANGII has direct effects on cancer growth, warranting further research into the role of an activated renin-angiotensin-aldosterone-system (RAAS) as a mechanistic link between CVD and cancer growth in AT1-positive tumors.
