Zusammenfassung: | Abstract Purpose This study is aimed at understanding and defining the current patterns of care with respect to prostate brachytherapy for patients with intermediate-risk localized disease in the combined academic and community setting. Methods and materials A nomogram-based survey was developed at the Seattle Prostate Institute defining the accepted criteria for intermediate-risk prostate cancer. Patients were defined as having intermediate-risk prostate cancer if they met one of the following criteria: prostate-specific antigen (PSA) >10 ng/dL, Gleason score (GS) ≥7, or cT2b or cT2c disease. Additional potential predictive factors including perineural invasion (PNI), GS 3 + 4 vs. 4 + 3, and high-volume disease were included. Results In the absence of PNI, all of those surveyed would perform monotherapy for intermediate-risk patients, GS 7 (3 + 4) or PSA 10–20, with cT1c and |
