Uterine cervix tumor: clinical aspects of tumor control and time-dose fraction parameters

It was analyzed 35 patients with recurrence or residual tumor at the end of radiotherapy program. These patients were selected out of a group of 338 patients with cervix cancer who had also undergone the same radiotherapy program. Those patients were compared with a control group of 30 patients without clinical evidence of the disease, at the end of the treatment, from the same group of 338 patients. It was studied the clinical results considering the time-dose-fraction parameters (TDF) for radiation therapy program for each patient and factors that could modify it, and also modify the final survival results. No significant difference were shown in the study, for A point, but significant differences were shown for B point and for the external beam radiation group, which could be considered the cause of treatment failure.
