Despite widespread adoption of the six-item erectile function (EF) domain of the International Index of Erectile Function (IIEF) as a clinical trial end point, there are currently no objective data on what constitutes a minimal clinically important difference (MCID) in the EF domain. ⋯ The contextualization of treatment-related changes in terms of clinically relevant improvement is essential to understanding treatment efficacy, to interpreting results across studies, and to managing patients effectively. This analysis provides, for the first time, anchor-based estimates of MCIDs in the EF domain score of the IIEF.

Prostate cancer (PCa) is the most common cancer in men. Permanent interstitial low-dose-rate brachytherapy (LDR-BT) is a short-distance radiation therapy in which low-energy radioactive sources are implanted permanently into the prostate. ⋯ We found a low amount of evidence in studies that exclusively compared LDR-BT with other treatment modalities. LDR-BT may have some different physician-reported SAE and patient-reported outcomes. The current evidence is insufficient to allow a definitive conclusion about OS. Randomised trials focusing on long-term survival are needed to clarify the relevance of LDR-BT in patients with localised PCa.
