| Popis: | Objective: to evaluate the effectiveness of salvage radiotherapy in patients with recurrent prostate cancer after radical prostatectomy. Materials and methods. In the period from March 2009 to January 2015, 92 patients with prostate cancer and biochemical recurrences after radical prostatectomy underwent salvage radiotherapy with classic fractionation and hypofractionation of the radiation dose. Results and conclusion. Median follow-up duration was 40 months (12–78 months). Overall survival was 100 %. Local control was 100 %. One (1), 2, and 3-year disease-free survival in the whole patient group was 96, 91, and 86 %; in the hypofractionation group it was 98, 95, and 89 %; in the classical fractionation group it was 95, 87, and 84 %, respectively. We have determined that the period of doubling of prostate-specific antigen level of ≤6 months (p = 0.035) after surgical treatment and prostate-specific antigen level >0.5 ng/ml (p = 0.037) at the time of salvage radiotherapy are significantly associated with worse prognosis for treatment effectiveness. There weren’t any differences in late toxicity between the 2 patient groups. |
