TNNT2 and Wilms tumor: The main findings of this study can be summarised as follows: (a) A third of the patients studied had elevated levels of cTnT with less than 10% showing abnormalities on echocardiography; (b) nephroblastoma was the commonest malignancy seen in a third of the study patients; (c) more than three-quarters of the study patients received anthracycline-based chemotherapy (mainly doxorubicin) which was associated with elevated cTnT levels at higher doses.
