title: The early variation of left ventricular twisting function in patients with lymphoma received anthracycline therapy assessed by three-dimensional speckle tracking echocardiography.
abstract: BACKGROUND
  Anthracycline-induced cardiotoxicity remains a significant and unresolved issue in patients receiving chemotherapy. The aim of this study was to evaluate left ventricular (LV) twisting function by three-dimensional speckle tracking echocardiography (3D-STE) in patients with lymphoma after anthracycline therapy.
  
  
  METHODS
  One hundred and one patients with newly diagnosed diffuse large B-cell lymphoma who had planned to receive anthracycline chemotherapy were enrolled. LV apical rotation, basal rotation, twist, torsion, time to peak apical rotation and time to peak basal rotation were measured by 3D-STE at baseline, after the completion of two cycles and four cycles of the regimen, respectively. Apical-basal rotation delay was calculated as the difference between time to basal and time to apical rotation.
  
  
  RESULTS
  The results showed that LV apical rotation, basal rotation, twist and torsion declined progressively during the whole procedure (baseline vs. two and four cycles of the regimen, apical rotation: 12.5 ± ± 4.5° vs. 8.8 ± 3.6° vs. 6.0 ± 3.2°; basal rotation: -7.7 ± 3.0° vs. -5.9 ± 2.6° vs. -4.4 ± 2.5°; twist: 20.0 ± 6.4° vs. 14.5 ± 5.1° vs. 9.8 ± 4.5°; torsion: 2.9 ± 0.9°/cm vs. 2.1 ± 0.9°/cm vs. 1.4 ± 0.7°/cm; all p < 0.01). Furthermore, apical-basal rotation delay increased significantly after two cycles as well as after four cycles of the regimen (38.3 ± 67.9 ms vs. 66.7 ± 73.9 ms vs. 92.6 ± 96.9 ms; p < 0.01).
  
  
  CONCLUSIONS
  LV twisting function deteriorated in the early stage of anthracycline therapy in patients with lymphoma, which could be detected by 3D-STE sensitively.
