Objective: To determine whether patients with locally
advanced non-small cell lung cancer unsuitable for resection or
radical radiotherapy, and with minimal thoracic symptoms, shouldbe
given palliative thoracic radiotherapy immediately or as neededto
treatsymptoms. Design: Multicentre randomised controlledtrial. Setting: 23 centres in the United Kingdom, Ireland,and SouthAfrica. Participants: 230 patients with previously untreated, non-smallcell lung cancer that is locally too advanced for resection or
radical radiotherapy with curative intent, with minimal thoracic
symptoms, and with no indication for immediate thoracicradiotherapy.
Interventions: All patients were given supportive treatment
and were randomised to receive palliative thoracic radiotherapy
either immediately or delayed until needed to treat symptoms.The
recommended regimens were 17 Gy in two fractions one weekapart or
10 Gy as a singledose. Main outcome measures: Primarypatients
alive and without moderateor severe cough, chest pain, haemoptysis,
or dyspnoea six monthsfrom randomisation, as recorded by clinicians.
Secondaryqualityof life, adverse events,survival. Results: From December 1992 to May 1999, 230 patientswere
randomised. 104/115 of the patients in the immediate treatmentgroup
received thoracic radiotherapy (90 received one of the recommended
regimens). In the delayed treatment group, 48/115 (42%) patients
received thoracic radiotherapy (29 received one of the recommended
regimens); 64 (56%) died without receiving thoracic radiotherapy;the
remaining three (3%) were alive at the end of the study without
having received the treatment. For patients who received thoracic
radiotherapy, the median time to start was 15 days in the immediate
treatment group and 125 days in the delayed treatment group. The
primary outcome measure was achieved in 28% of the immediate treatmentgroup and 26% of patients from the delayed treatment group (27/97and 27/103, respectively; absolute difference 1.6%, 95% confidenceinterval -10.7% to 13.9%). No evidence of a difference was observedbetween the two treatment groups in terms of activity level, anxiety,depression, and psychological distress, as recorded by the patients.Adverse events were more common in the immediate treatment group.Neither group had a survival advantage (hazard ratio 0.95, 0.73to
1.24; P=0.71). Median survival was 8.3 months and 7.9 months,and the
survival rates were 31% and 29% at 12 months, for theimmediate and
delayed treatment groups,respectively. Conclusion: In minimally symptomatic patients with locally
advanced non-small cell lung cancer, no persuasive evidence wasfound
to indicate that giving immediate palliative thoracic radiotherapy
improves symptom control, quality of life, or survival when compared
with delaying until symptoms requiretreatment.
What is already known on this topic
Radiotherapy is commonly given to patients with inoperable non-small cell
lung cancer in the United Kingdom
One or two fractions of palliative radiotherapy can control thoracic
symptoms
What this study adds
In the group of patients with no symptoms or only minimal symptoms,
palliative thoracic radiotherapy can be safely deferred until significant
thoracic symptoms appear
Compared with immediate, palliative radiotherapy, no evidence exists that
such a policy affects patients' survival or levels of activity, anxiety, or
depression
