Chest radiography or computed tomography to assess the response of lung cancer to radiotherapy.
In 58 patients with lung cancer the response of the primary tumour to treatment with CHART was followed by both chest radiograph and computed tomographic (CT) scan. Clear evidence of complete response was seen by chest radiograph in 11 patients and by CT scan in 20. If all studies showing no definite tumour, regardless of the quality of the study, were included then complete response was considered to have occurred in 25 as indicated by chest radiograph and in 22 by CT scan. The validity of the observations was tested by life table analysis comparing the survival of those showing complete regression with those whose response was incomplete. Comparison based on the CT scan findings showed the greatest significance (P = 0.0001), while that based on the chest radiograph findings showed the least (P = 0.044).
