  • Title: [Comparative clinical and dosimetric analysis of radiotherapy variants in cervical cancer].
    Author: Beĭbutov ShM, Kazhlaeva UI, Samsonova ZA.
    Journal: Vopr Onkol; 1977; 23(2):107-11. PubMed ID: 855247.
    Abstract:
    The authors estimated comparatively in 200 clinical patients the results of external irradiation of cervical cancer using two variants of gammatherapy: standard, 4--5 fields irradiation and improved one from 2 central contralateral fields in combination with a splitting lead block. The use of the improved variant of distance gammatherapy, compared with the standard one enabled the authors: 1) to reduce irradiation load on the minor pelvis organs and pelvic bones as much as 2--25 times; 2) to gain more even distribution of radiation on the lesion focus; 3) to reduce irradiation load on the organism, as a whole, in adequate focal dosage at point A and B, thus lessening radiation complications; 4) to simplify considerably centring and to shorten the exposure procedure that contributes to better efficiency of a gammatherapy machine; 5) to increase the effectiveness of combined radiotherapy for cancer of the uterine neck.
