[Evolution of the dosimetric criteria of the curietherapy in carcinoma of uterine cervix (author's transl)].

The difficulties which arise when comparing the different therapeutic attitudes concerning the treatment in the curable stages of cancer of the uterine cervix have led us to the formation of dosimetric criteria to be employed in the analysis of the intracavity therapy. We have established points of reference which can be utilized irregardless of the intracavitary technique therapy. We have established points of reference which can be utilized irregardless of the intracavitary technique employed. Furthermore, we have analysed those patients who have received the same dose of external irradiation in an effort to establish as the only variable the intracavitary treatment. Forty patients, receiving 4,000 rads tumor dose in 4 weeks, were reviewed and demonstrated a correlation between the reference volume of the intracavitary treatment (as defined by the three dimensions W, H, T) and eventual complications (4 cases of Rectitis 1). We now feel that with the utilisation of these dosimetric criteria we will be able to: minimize the risk of complication without augmenting the indicence of local-regional failures; facilitate the objective comparison of the efficacity of the different intracavitary techniques presently employed at the major treatment centers.
