Grid therapy and carcinoma of the lung

When a cancer of the lung is operable, radiotherapy might be considered as an alternative to surgery. In support of this there is Hilton’s work and also the series of cases published by Bromley and Szur in which 66 patients were given preoperative radiotherapy. In 44% of these no histological evidence of residual tumour could be found when the excised lung was examined.
When the disease has advanced to the stage of being inoperable, the results of radical radiotherapy are poor. Only a few per cent. of the patients can hope to be cured. By using a grid it is possible to give a radical dose ofx-ray treatment without causing undue morbidity and the patient has at least the chance of being among the few who are saved.
Palliative radiotherapy is quite effective in relieving the symptoms of lung cancer and one is justified in giving the treatment routinely. However, it does not appear to prolong life to any significant extent. (Fig. 5.)
