Study hypothesis
The CHART trials, the largest of their kind in Europe, have shown an improvement in survival of 10% at 2 years in patients with carcinoma of the bronchus treated with CHART, as compared with conventional radiotherapy. In the head and neck trial, the overall benefit in local tumour control does not reach statistical significance but this is reached in important sub-groups. There is however as reduction in morbidity in this trial giving a therapeutic benefit. To determine the true usefulness of a new radiotherapy schedule and to build on the improvements obtained the effect on therapeutic ratio must be defined over time. During the trial full data has now been gathered and analysed concerned with acute reactions and in the follow up late morbidity and from this data we have been able to make important contributions to radiobiological knowledge in humans particularly by a calculation of the repair half-times of normal tissue being about twice as long as previously known.
