FOXA1 is a transcription factor involved in androgen signaling with relevance for lineage specific gene expression of the prostate. The expression was analyzed by immunohistochemistry on a tissue microarray containing 11,152 prostate cancer specimens. Results were compared to tumor phenotype, biochemical recurrence, androgen receptor expression, ERG status and other recurrent genomic alterations. FOXA1 expression was detectable in 97.6% of 8,227 interpretable cancers and considered strong in 28.5%, moderate in 46...

PURPOSE OF REVIEW: Active surveillance is an established treatment option for men with localized, low-risk prostate cancer (CaP). It entails the postponement of immediate therapy with the option of delayed intervention upon disease progression. The rate of clinical progression and need for treatment on active surveillance is approximately 50% over 15 years. The present review summarizes recent data on current methods, attempting to prevent clinical progression. RECENT FINDINGS: Patient selection for active surveillance is the first mandatory step required to lower progression...

INTRODUCTION: The classical pathway for the diagnosis of prostate cancer is transrectal ultrasound-guided (TRUS) biopsy of the prostate initiated on the basis of a raised prostate-specific antigen (PSA). An alternative pathway is to perform multi-parametricMRI (MPMRI) to localise cancer and to use this information to influence the decision for, and conduct of, a subsequent biopsy, known as an MPMRI-targeted biopsy. An MPMRI pathway has been shown to detect a similar or greater amount of clinically significant cancer as TRUS biopsy but has several advantages, including the potential to biopsy fewer men with fewer cores...

BACKGROUND: Prostate cancer is the most frequently diagnosed cancer in men. Histological tumour grade is a strong predictor of outcome and helps determine what treatment options are offered. There are numerous studies on Inter-observer agreement/variability on prostate cancer grading. In this study, we were looking to establish if disconcordance between pathologists when grading prostate cancer, could affect treatment options offered to men. METHODS: In Greater Manchester West Cancer Sector, all prostate cancer biopsies undergo a central review by three pathologists with a special interest in urological pathology prior to referral for treatment at specialist centres...

INTRODUCTION: Prostate cancer is a heterogeneous disease, and risk stratification systems have been proposed to guide treatment decisions. However, significant heterogeneity remains for those with unfavorable-risk disease. METHODS: This study included 3335 patients undergoing radical prostatectomy without adjuvant radiotherapy in the SEARCH database. High-risk patients were dichotomized into standard and very high-risk (VHR) groups based on primary Gleason pattern, percentage of positive biopsy cores (PPBC), number of NCCN high-risk factors, and stage T3b-T4 disease...

Active surveillance has gained popularity as an acceptable management option for men with low-risk prostate cancer. Successful utilization of this strategy can delay or prevent unnecessary interventions - thereby reducing morbidity associated with overtreatment. The usefulness of active surveillance primarily depends on correct identification of patients with low-risk disease. However, current population-wide algorithms and tools do not adequately exclude high-risk disease, thereby limiting the confidence of clinicians and patients to go on active surveillance...

Prostate cancer is the most common male malignant tumor in Germany, which thus places growing demands on differentiated imaging and risk-adapted therapeutic approaches. Multiparametric MRI (mpMRI) of the prostate enables reliable detection of clinically significant cancers and is currently the leading imaging modality for the detection, characterization, and local staging of prostate cancer. According to the German S3 guideline, mpMRI of the prostate is currently primarily recommended in patients with previous negative TRUS biopsies and persisting tumor suspicion...

BACKGROUND/AIM: Salvage androgen-deprivation therapy (ADT) is standard treatment for recurrent prostate cancer after curative therapy. However, the prognostic impact of different treatment modalities on the time to castration resistance remains unclear. In this study, we investigated the prognosis of men treated with salvage ADT after initial radical prostatectomy or radiotherapy for prostate cancer. PATIENTS AND METHODS: Between 2000 and 2013, 149 Japanese men with recurrent prostate cancer who were initially treated with radical prostatectomy (n=95) or radiotherapy (n=54) and were subsequently treated with salvage ADT after disease recurrence were enrolled in this study...
