Study Investigating the Cardiotoxicity of Anthracyclines in Patients With Diffuse Large B-Cell

The study was designed as a prospective observational multicenter study to evaluate the role of possible early markers of cardiotoxicity estimating an overall maximum risk equal to 20% of patients. The sample size, required to obtain an estimate of conventional anthracycline cardiotoxicity in the population, has been calculated with a confidence interval of 95% and a maximum acceptable error of ± 0.075. According to the conditions described above, the sample size of patients treated with conventional anthracycline results to be 124 patients.

Considering a 10-15% of not evaluable patients, the sample size is fixed at 150 patients treated with R-CHOP. The duration of the enrollment phase is defined in 2 years.

With this sample size should be possible to assess the risk of cardiotoxicity related to predictors with a worst group frequency at least of 10%.
