Description of intervention(s) / exposure
Patients will have an ECG performed prior to commencing radiation therapy and at the end of their treatment course. Patients will undergo blood sampling at Day 1 to Day 5 of the first week of radiation therapy which will be performed on arrival for their treatment. Following the first week blood will be sampled only on Day 1 of the subsequent weeks for the duration of the treatment schedule. Patients will also undergo cardiac ultrasound with transthoracic echocardiography with a machine capable of calculating strain rates on the images obtained. This will be performed prior to commencing radiation therapy, immediately after finishing the 6-week course of radiation therapy and at least 12-months after treatment and will be assessed by a cardiologist for reduction in left ventricular function.

Statistical methods / analysis
Normalised data will be expressed as mean ± standard deviation. Continuous data will be evaluated by Student’s t-test or Mann-Whitney U test as appropriate. Categorical data will be expressed as n (%) and analyzed using Fisher’s exact test. Differences in paired samples will be evaluated by Wilcoxon signed-rank test. Two-tailed p-values <0.05 will be considered significant. A sample size calculation has not been performed for this preliminary investigation, as it is a pilot study.
