title: [Examinations carried out in order to determine the effects of a radiotherapy on the immunity situation of tumor patients (author's transl)].
abstract: In order to evaluate the immunity situation, the percentage of B- and T-lymphocytes in the peripheral blood of tumor patients was determined before, during, and after radiotherapy. Corresponding to the tumor types, the patients were submitted to adequate irradiations with different localizations, field sizes, and doses. Most of the patients had a reduced percentage of T-cells which partly was accompanied by a so-called reverse effect, i.e. a relative increase of the percentage of B-cells. It was not possible to demonstrate any connexion between the decrease of the number of B- or T-cells and the field size, localization, and dose height.
