Prostate cancer is a main urological disease associated with significant morbidity and mortality. Radical prostatectomy and radiotherapy are potentially curative for localized prostate cancer, while androgen deprivation therapy is the initial systemic therapy for metastatic prostate disease. However, despite temporary response, most patients relapse and evolve into castration resistant cancer.Epithelial-mesenchymal transition (EMT) is a complex gradual process that occurs during embryonic development and/or tumor progression...

INTRODUCTION: Prostate cancer is the most common malignant disease in men. The number of cases of prostate cancer has increased dramatically in recent 20 years. Radical prostatectomy is a surgical method for the first-line treatment of localised prostate cancer. We performed the first robotic-assisted radical prostatectomy on December 16th, 2005, achieved the boundary of 1000 robotic-assisted radical prostatectomies in 2012, and in 2015, we successfully completed the 1500th robotic-assisted operation on the prostate...

Infiltrating ductal carcinoma (IDC) is a rare histologic subtype of prostate cancer. We investigated the clinicopathological features and prognosis of IDC compared with acinar cell carcinoma (ACC). We identified 3814 men diagnosed with prostate cancer between 2004 to and 2013 in the Surveillance, Epidemiology, and End Results database, including 511 IDC and 3303 ACC cases. Prostate cancer-specific survival (PCSS) was compared using univariate and multivariate Cox proportional hazards models. Generally, IDC occurred in older men (≥ 65 years old) and presented with larger sizes, and higher grades, American Joint Committee on Cancer (AJCC) stages, AJCC T stages, lymph node positive rates and metastasis rates...

BACKGROUND: In patients with prostate cancer (PCa), the lack of clear guidelines on the use of radiotherapy after radical prostatectomy (RP) invites unwanted variation of this treatment. We describe the hazard ratios and probabilities related to the use of post-RP radiotherapy. MATERIAL AND METHODS: Data were collected from the Cancer Registry of Norway and nine radiotherapy units. All patients were diagnosed with a non-metastatic PCa from January 2004 through June 2011...

BACKGROUND: Patients with prostate cancer and their providers face uncertainty as they consider adjuvant radiotherapy (ART) or salvage radiotherapy (SRT) after undergoing radical prostatectomy. The authors prospectively evaluated the impact of the Decipher test, which predicts metastasis risk after radical prostatectomy, on decision making for ART and SRT. METHODS: A total of 150 patients who were considering ART and 115 who were considering SRT were enrolled. Providers submitted a management recommendation before processing the Decipher test and again at the time of receipt of the test results...

Purpose: Korean patients with prostate cancer (PC) typically present with a more aggressive disease than patients in Western populations. Consequently, it is unclear if the current criteria for active surveillance (AS) can safely be applied to Korean patients. Therefore, this study was conducted to define appropriate selection criteria for AS for patients with PC in Korea. Materials and Methods: We conducted a multicenter retrospective study of 2126 patients with low risk PC who actually underwent radical prostatectomy...

Background: To examine how surgical robot emergence affects prostate-cancer patient behavior in seeking radical prostatectomy focusing on geographical accessibility. Methods: In Japan, robotic surgery was approved in April 2012. Based on data in the Japanese Diagnosis Procedure Combination database between April 2012 and March 2014, distance to nearest surgical robot and interval days to radical prostatectomy (divided by mean interval in 2011: % interval days to radical prostatectomy) were calculated for individual radical prostatectomy cases at non-robotic hospitals...

The differential diagnosis of benign and malignant changes in the prostate presents still definite difficulties; the antibody panel existing for these purposes is imperfect. Fatty acid synthase (FASN) is an androgen-regulated enzyme required for de novo lipogenesis. A number of studies have noted increased expression of the gene encoding this protein in tumors and precancerous lesions of different locations. AIM: Тo estimate the diagnostic value of analyzing the expression of FASN in prostate neoplasias...

Abdominal straining associated with voiding dysfunction or constipation has traditionally been associated with the development of abdominal wall hernias. Thus, classic general surgery dictum recommends that any coexistent bladder outlet obstruction should be addressed by the urologist before patients undergo surgical repair of a hernia. While organ-confined prostate cancer is usually not associated with the development of lower urinary tract symptoms, a modest proportion of patients treated with radical prostatectomy may have coexisting benign prostatic hyperplasia with elevated symptom scores and hernias may be incidentally detected at the time of surgery...

PURPOSE OF REVIEW: Extraperitoneal robot-assisted radical prostatectomy (eRARP) is an alternative to the more commonly employed transperitoneal RARP (tRARP) for treatment of clinically localized prostate cancer. The purpose of this review is to discuss indications in which eRARP would be a more favorable approach in comparison to tRARP. In addition, we will discuss the safety and technique of eRARP. RECENT FINDINGS: Recently published work has highlighted the outcomes and safety of eRARP in comparison to tRARP; specifically that eRARP is not inferior to tRARP...

PURPOSE/BACKGROUND: [(18)F]fluoroethylcholine ((18)FECH) has been shown to be a valuable PET-tracer in recurrent prostate cancer (PCa), but still has limited accuracy. RM2 is a gastrin-releasing peptide receptor (GRPr) antagonist that binds to GRPr on PCa cells. Recent studies suggest that GRPr imaging with PET/CT is a promising technique for staging and restaging of PCa. We explore the value of GRPr-PET using the (68)Ga-labeled GRPr antagonist RM2 in a selected population of patients with biochemically recurrent PCa and a negative/inconclusive (18)FECH-PET/CT...

INTRODUCTION: Prostate cancer is the most prevalent malignant neoplasia among men worldwide. Several prognostic factors, including Gleason's score, the measurement of serum prostate-specific antigen (PSA) and the evaluation of the percentage of fragments affected by cancer on prostate biopsy, have already been established. Age alone, however, has yet to be studied as a prognostic factor independently from other known factors. The aim of the present study was to compare the characteristics and the evolution of prostate cancer in different age groups using a paired analysis for patients with equivalent known prognostic factors...
