“…In Great Britain, 'CHART' (continuous hyperfractionated accelerated radiotherapy) has been notable among these trials, with a total recruitment of nearly 1000 patients. We are waiting further follow-up before full results of this and of some of the other recently completed trials will be available, but enough data has been collected for some preliminary comments to be made (Horiot et al, 1996;Saunders et al, 1996), and one early trial demands a specific mention. The EORTC radiotherapy group conducted a trial of a 'pure' hyperfractionated regimen and compared it in a randomized trial with conventional radiotherapy, given over the same overall time for tumours of the oropharynx (Horiot et al, 1996).…”
