Abstract
Although encouraging results in terms of disease control and acute toxicities have been reported with extreme hypofractionation in different prostate SBRT series, the possible impact on health-related quality of life (QoL) of SBRT treatments represents one of the highest research questions and constitutes a central consideration for treatment decision.
By merging physician-reported toxicities and patient-reported outcomes, in the majority of the published series only a transient decline in the urinary and bowel domains was observed within the first 3 months after SBRT, with a complete and durable recovery to baseline or even better within 6 months after SBRT. Comparative analyses between SBRT and other treatment techniques as well as fractionation schedules confirm the modest impact of SBRT on QoL, with only minimal regret rates for patients treated with this modality. Waiting for results of randomized phase III trials, a standardized assessment of QoL and the use of modern SBRT techniques able to minimize radiation-induced toxicities will probably further improve in the next future the QoL impact of this promising treatment modality.
