A contribution to the comparison of the efficacy of radiotherapeutic procedures in cervical carcinoma.

This paper presents a new method in which the regression velocity of cervical carcinoma is measured by computer tomography and the results evaluated by two statistical methods: non-linear regression analysis and survival analysis. By means of this approach it was possible to compare the early effect of therapy in patients treated with intracavitary application of 226Ra plus external radiotherapy with those treated with 252Cf, 226Ra and extended radiotherapy. In the latter group a higher efficacy of the therapy was demonstrated by both statistical methods.
