Impact of taxane type and cumulative dose on myocardial deformation in breast cancer patients: Paclitaxel vs. docetaxel

Key Points

• This research aims to evaluate how different taxane types and their cumulative doses affect myocardial deformation in breast cancer patients.
• Comparison of myocardial deformation metrics between paclitaxel and docetaxel groups.
• Analysis of cumulative dosage effects on heart function.
• Patient population includes individuals receiving chemotherapy for breast cancer.
• Paclitaxel group showed significantly reduced myocardial deformation compared to docetaxel (HR 1.2, 95% CI 1.1-1.4, p=0.01).
• Higher cumulative doses correlated with increased myocardial dysfunction in both groups.
• Findings suggest taxane type should be considered in treatment plans to preserve heart health.
