Recommendation for the contouring of limbic system in patients receiving radiation treatment: A pictorial review for the everyday practice and education.

Aims: The limbic circuit (LC) is devoted to linking emotion to behavior and cognition. The injury this system results in post-RT cognitive dysfunction. The aim of this study is to create the first radiation oncologist's practical MR-based contouring guide for the delineation of the LC for the everyday clinical practice and education.

Are we ready for a paradigm shift from high-dose conventional to moderate hypofractionated radiotherapy in intermediate-high risk prostate cancer? A systematic review of randomized controlled trials with trial sequential analysis.

Aim: to evaluate efficacy and late toxicity of moderate hypofractionated (HFRT) over high-dose (>76 Gy) conventional radiotherapy (CRT) in a non-inferiority perspective.

Methods: Randomized controlled trials (RCTs) were included. HFRT regimens were deemed non-inferior to high-dose CRT if the computed CI for the overall RR did not exceed the non-inferiority margin of 7%.
