Abstract

Purpose:Prostatic adenocarcinoma with extraprostatic extension detected on prostate needle biopsy is an uncommon finding. We describe clinical and pathological findings in a large cohort of patients with prostatic adenocarcinoma who were treated with radical prostatectomy and in whom extraprostatic extension was identified on prostate needle biopsy.Materials and Methods:Using our institutional pathology database we identified 83 patients with prostatic adenocarcinoma and with extraprostatic extension on prostate needle biopsy between 2000 to 2018 who underwent radical prostatectomy and had clinical followup information. Clinical and pathological outcomes were examined.Results:Of the 83 patients 54 (65%) presented with clinical stage T2 or greater disease. On biopsy 50 of the 83 patients (60%) had Grade Group 4-5 and 66 (81%) had perineural invasion. Extraprostatic extension was confirmed in the radical prostatectomy specimen in 81 of 83 cases (98%). At radical prostatectomy 49 of 83 patients (59%) had positive surgical margins, 37 (45%) had seminal vesicle invasion and 30 (37%) had lymph node involvement. Median followup after radical prostatectomy was 2 years. Overall 34 of 76 men (45%) received postoperative radiation a median of 1 year after radical prostatectomy and 8 (11%) received chemotherapy a median of 2 years after radical prostatectomy. The 3-year biochemical recurrence-free survival rate was 48.4% (95% CI 0.345-0.610) and the 3-year metastasis-free survival rate was 75.2% (95% CI 0.603-0.851).Conclusions:Patients in whom extraprostatic extension is detected on prostate needle biopsy almost always have extraprostatic disease and markedly adverse pathology findings at radical prostatectomy. Many of them experience biochemical recurrence and most will require multimodal therapy. These data can be useful to counsel such patients in regard to the treatment approach and the expected outcomes after surgery.
