Methods: We studied 751 patients with T1- 3N0M0 prostate cancer treated with radical prostatectomy at our institution between 2000 and 2012. Patients with neoadjuvant treatments were excluded. We retrospectively reviewed the clinical and pathological outcomes for patients with VLR or LR prostate cancers that were classified by NCCN guidelines. Results: We identified 45 patients with VLR and 137 with LR prostate cancer. Non-biochemical recurrence rate at 5-year for 45 patients with VLR was 86.9% and 81.2% for 137 patients with LR (p = 0.56). However, none of the 19 patients >65 years old with VLR progressed, while 19% of 26 patients ≤65 years old with VLR cancer, 14% of patients >65 years old with LR cancer, and 17% of patients ≤65 years old with LR cancer progressed during the follow-up period (p = 0.04, p = 0.04 and p = 0.05, respectively). In analyses of prostatectomy specimens, both VLR and LR had similarly favorable outcomes, but patients >65 years old with VLR had the smallest tumors, with a mean of 5 mm in diameter. Conclusions: Our results support the treatment strategy of the NCCN that patients with VLR cancer and age >65 years old are good candidates for active surveillance, and that other treatment options—including active surveillance and aggressive treatments—can be applied to the remaining patients with VLR or LR cancers.展开更多

Purpose: To investigate the association between travel distance to a treatment facility and initial treatment choice among young men with low-risk prostate cancer in a rural state. Methods: A retrospective medical charts review was conducted of young men (65 years or younger) newly diagnosed with low-risk prostate cancer from January 1, 2005 through December 31, 2014 who were treated with either active surveillance, radical prostatectomy, or brachytherapy at either of the two major hospital systems in Bismarck, ND, USA. Results: Information on a random sample of 242 patients was studied. The majority of patients (66%) received radical prostatectomy. Patients who received radical prostatectomy were significantly younger (p-value 0.001). PSA at diagnosis, clinical stage, and Gleason score were not associated with treatment choice (p-value = 0.06;p-value = 0.1794;and p-value = 1.00;respectively). Adjusting for age at diagnosis, PSA at diagnosis, and treatment facility, treatment choice was not associated with travel distance (p-value = 0.309). Patients treated at St. Alexius facility were more likely to undergo radical prostatectomy than Sanford health patients (p-value Conclusions: We found no association between travel distance and treatment choice for low-risk prostate cancer.
