The lymphocyte response and prognosis in cancer of the lung

Abstract
One hundred and twenty cases of cancer of the lung have been tested for their lymphocyte transformation to phytohaemagglutinin (PHA) before and after treatment by radical radiotherapy. The average response of these patients was lower than that of the controls. The fall in the lymphocyte response during treatment was calculated. The pre-treatment lymphocyte response with PHA was not related to survival after treatment. The fall in the lymphocyte response during treatment was related to the survival of the patients after treatment.
