ABSTRACT
To evaluate the changes in left ventricular myocardial function in patients with colorectal cancer undergoing chemotherapy with mFOLFOX6 (oxaliplatin + 5-fluorouracil + calcium folinate) using three-dimensional speckle-tracking echocardiography (3D-STE). Data were collected from 30 patients diagnosed with colorectal cancer in our hospital treated with mFOLFOX6. We used 3D-STE to measure the following parameters of left ventricle function global longitudinal strain (GLS), global area strain (GAS), global circumferential strain (GCS), global radial strain (GRS), and left ventricular twist (LVtw). Myocardial composite index (MCI) was calculated from measured values (MCI = GLS × LVtw). The above listed parameters were compared before and after chemotherapy. Receiver operating curves (ROC) were prepared for each parameter and analyzed to identify correlations among MCI, LVEF, GLS, and cTnT. Compared with the pre-chemotherapy state, the absolute values of MCI, LVtw, GLS, GAS, GCS, and GRS decreased with increasing cumulative doses of chemotherapeutic drugs. The absolute values of GAS, GLS, MCI, and LVtw decreased after the first cycle of chemotherapy (P < 0.05). The areas under the ROC curves for MCI and GLS were 0.903 and 0.838, respectively. The correlation observed between MCI and cTnT (r = - 0.7228) was found to be stronger than that between GLS and cTnT (r = - 0.6008). In conclusion, 3D-STE may help detect early changes in left ventricular myocardial function caused by mFOLFOX6 treatment in patients with colorectal cancer. MCI is a relatively sensitive index among the various measurable parameters.
