Optimal radiotherapy treatment planning for carcinoma of the cervix uteri

A study is described in which an optimal time-dose-fractionation (TDF) value for radiotherapy of carcinoma of the cervix uteri is found using clinical data for points 2 cm from the cervical os proximally along the direction of the cervical canal and 2 cm laterally to the canal. The optimal TDF value was found to be 127 +/- 10 for regimens utilizing external beam cobalt 60 irradiation (or external irradiation of equivalent quality) in combination with intracavitary radium irradiation.
