| Summary: | Background Anthracycline‐based chemotherapy is a vital treatment for various cancers but carries notable risks of cardiotoxicity. This study aimed to assess how different body mass index values and glycemic status influence the risk of major adverse cardiovascular events (MACE) in chemotherapy‐naïve adult patients with cancer treated with anthracyclines. Methods This retrospective cohort included 11 393 chemotherapy‐naïve patients who initiated anthracycline‐based chemotherapy between 2000 and 2019. Follow‐up began from the first anthracycline dose. Body mass index was categorized as underweight/normal weight (<25 kg/m2), overweight (25–29.9 kg/m2), and obese (≥30 kg/m2). Glycemic status was classified as normoglycemic or diabetes/prediabetes (diabetes: hemoglobin A1c ≥6.5% or fasting glucose ≥126 mg/dL; prediabetes: hemoglobin A1c 5.7%–6.4% or fasting glucose 100–125 mg/dL). Results Over a median follow‐up of 8.7 years, 985 (8.64%) patients experienced MACE. Obesity was significantly associated with an increased risk of MACE (hazard ratio [HR], 1.38 [95% CI, 1.10–1.73], reference: underweight/normal weight) and heart failure hospitalization, and diabetes/prediabetes also significantly predicted MACE (HR, 1.28 [95% CI, 1.10–1.50], reference: normoglycemic). Notably, overweight (HR, 0.85 [95% CI, 0.80–0.91]) and obesity (HR, 0.85 [95% CI, 0.74–0.96]) were associated with lower risk of all‐cause mortality. Joint analysis revealed that patients with both obesity and diabetes/prediabetes had the highest risk of MACE (HR, 1.74 [95% CI, 1.28–2.37]) and heart failure hospitalization (HR, 1.99 [95% CI, 1.41–2.81]). Conclusions In patients with cancer undergoing anthracycline‐based chemotherapy, both body mass index and glycemic status significantly affect cardiovascular risks, with the highest risk observed in those with concurrent obesity and diabetes/prediabetes, emphasizing the need for tailored risk assessment and management. |
