    Author: Konecný M, Kudlicková Z, Malír A, Pecina J, Rasovská O, Spurný V.
    Journal: Czech Med; 1981; 4(3):174-82. PubMed ID: 7307850.
    Abstract:
    In the presented work we have tested another fractionation schemes than simple fractionation in some so-called radioresistant tumors, i. e. in breast cancer and malignant melanoma. We have found the advantage of the irradiation with divided series (split irradiation) namely in malignant skin melanoma where we gained therapeutic results with 58% 5-year survival. Periodical irradiation especially with higher fractions once a week had encouraging success in advanced stages of the breast cancer where a single fraction of 8 Gy/tumor up to total dose of 40 Gy/tumor was determined as optimal. With the use of higher fractions more pronounced late postirradiation changes are to be expected. Fraction schemes were compared using NSD and TDF equations.
