Abstract
Two recent studies carried out by the Medical Research Council Lung Cancer Working Party have suggested that large fraction radiotherapy to the chest in either 10-Gy single fraction or 17-Gy two-fraction doses, 1 week apart, is safe and effective for patients who require palliation for bronchogenic cancer. The Beatson Oncology Centre, Glasgow, participated in the original MRC trial and anecdotal reports of acute chest pains, fevers, sweats and rigors in some patients during the first 24-hour period after radiotherapy treatment were noted. These acute side-effects were not monitored during the Medical Research Council trials. It was felt that this area warranted further evaluation in order to identify the incidence of such acute side-effects and to what extent they caused a reduction in the patients’remaining quality of life. A pilot study of 10 patients confirmed the manifestation of the side-effects reported anecdotally in the MRC trial. It was on this basis that the study was extended, with a further 51 patients being invited to participate over a 4-month period. The findings indicate a significant incidence of adverse side-effects in patients receiving large fraction radiotherapy to the chest in either 10-Gy single fraction or 17-Gy two-fraction doses, but that these are transient and do not cause unacceptable disruption to the patients over an extended period.
