Objective: To evaluate the survival rate and risk factors of distant metastasis in stage I non-seminomatous germ cell tumor (NSGCT) cases without adjuvant treatments. Methods: A national testicular cancer survey of cases newly diagnosed in 2005 and 2008 was conducted by the Japanese Urological Association in 2011. In 159 stage I NSGCT cases, 132 were followed by active surveillance after high orchiectomy. Their recurrence-free survival rate (RFS) was compared with 27 cases that received adjuvant treatments, and clinical and pathological parameters were explored to identify significant risk factors of recurrence...

OBJECTIVES: The study aimed to evaluate associations of prostatic chronic inflammation (PCI) with prostate cancer (PCA) grade groups by the International Society of Urological Pathology (ISUP). METHODS: The study evaluated retrospectively 738 cases. The patient population was sampled into 3 groups collecting cases without and with PCA including subjects with lSUP grade group 1 and grade groups 2-5. RESULTS: PCI was assessed in 185 patients (25...

BACKGROUND: The randomized controlled PSAInForm study aims to investigate the effects of a computer-based decision aid which informs men in the age group 55-69 years about advantages and disadvantages of PSA testing. In preparation for the study, the current PSA testing practice in the Münster district was assessed. MATERIALS AND METHODS: The frequencies of early detection examinations, medically indicated PSA tests, and prostate biopsies in the Münster district were determined, using aggregated data from the regional association of Statutory Health Insurance (SHI) Physicians in Westfalen-Lippe...

The biology of masculinization is fundamentally important for understanding the embryonic developmental processes that are involved in the development of the male reproductive tract, external genitalia, and also the tumorigenesis of prostate cancer. The molecular mechanisms of masculinization are of interest to many researchers and clinicians involved in varied fields, including molecular developmental biology, cancer research, endocrinology, and urology. Androgen signalling is mediated by the nuclear androgen receptor, which has fundamental roles in masculinization during development...

This mini-review article discusses past and present prostate-focused research on telomere and telomerase biology conducted at Johns Hopkins, through the eyes of a Donald S Coffey trainee. Included are past discoveries of abnormalities in telomere biology in the context of prostate cancer and its pre-malignant precursor prostatic intraepithelial neoplasia (PIN); the finding that telomerase activity is androgen-regulated in the prostate, and the potential role of telomerase in prostate epithelial stem cells. Also reviewed are more recent results showing that in situ telomere length measurements in patient tissue specimens may have utility in risk assessment and as a prognostic biomarker...

This mini-review article is part of a special issue dedicated to Donald S. Coffey, a pioneer translational research scientist, exemplary mentor, and leader in urologic and urologic oncology research. This article first briefly reflects on life and scientific lessons from Don Coffey. It then reviews the development of two prostate cancer targeting RNA aptamers, xPSM-A9 and xPSM-A10, through in vitro selection for aptamers that bind to the extracellular domain of the Prostate Specific Membrane Antigen (PSMA)...

Prostate cancer is the most common solid cancer among American men. Although there are various modalities for treatment, including radical prostatectomy among many others, the former is, nevertheless, not without any accompanied complications. Other than the well-known surgical complications such as erectile dysfunction, urinary incontinence, and voiding dysfunction, osteomyelitis of the symphysis pubis is not a well-understood complication, with various hypotheses explaining its pathogenesis. Although osteomyelitis of the pubis symphysis has been reported after endoscopic urological procedures such as transurethral resection of the prostate, it has rarely been reported after robotic surgeries...

OBJECTIVE: The treatment of cervical cancer can result in genitourinary morbidity. We measured selected urologic procedures after the treatment of cervical cancer with either surgery or radiation. METHODS: We used administrative data from the province of Ontario Canada to identify adult women who had nonmetastatic cervical cancer and were treated with surgery or radiation between 1994 and 2014. Study outcomes were surgical or procedure codes representing ureteric repair or fistula repair...

Background: For over 100 years white-light cystoscopy has remained the gold-standard technique for the detection of bladder cancer (BCa). Some limitations in the detection of flat lesions (CIS), the differentiation between inflammation and malignancy, the inaccurate determination of the tumor margin status as well as the tumor depth, have led to a variety of technological improvements. The aim of this review is to evaluate the impact of these improvements in the diagnosis of BCa and their effectiveness in clinical practice...

Background: The aim of this study was to compare oncologic outcomes of radical prostatectomy (RP) with brachytherapy (BT). Methods: A literature review was conducted according to the 'Preferred reporting items for systematic reviews and meta-analyses' (PRISMA) statement. We included studies reporting comparative oncologic outcomes of RP versus BT for localized prostate cancer (PCa). From each comparative study, we extracted the study design, the number and features of the included patients, and the oncologic outcomes expressed as all-cause mortality (ACM), PCa-specific mortality (PCSM) or, when the former were unavailable, as biochemical recurrence (BCR)...

CONTEXT: To date, established risk factors for prostate cancer (PCa) are limited to age, race, family history, and certain genetic polymorphisms. Despite great research efforts, available evidence on potentially modifiable risk factors is conflicting. Moreover, most studies on PCa risk factors did not consider the impact of prostate-specific antigen (PSA) testing on PCa diagnosis. OBJECTIVE: To provide a detailed overview of the latest evidence on the role of metabolic diseases, drugs, and dietary factors for risk of PCa incidence, recurrence, and survival in men exposed to PSA testing...

Radiotherapy (primary, adjunctive or salvage) is a powerful tool in the treatment of pelvic malignancy. Dose escalation has improved cancer outcomes. However it requires accurate targeting in order to limit toxicity. Acute toxicity manifests during and in the first few months after treatment. Late toxicity may occur many years after treatment has been completed. This article is protected by copyright. All rights reserved.

A 56-year-old man with advanced RCC and a past medical history of type 2 diabetes underwent a radical left nephrectomy following a histological diagnosis of papillary RCC, G2, INF b, pT3, V1 in 1999. In 2008, sorafenib was started to treat multiple pulmonary metastases of RCC. In 2011, sorafenib was switched to sunitinib when radiologic progression was observed. In 2014, sunitinib was switched to axitinib when further radiologic progression was observed. In 2015, the patient was referred to Yazawa clinic for homecare urology when hospital visits became difficult due to cancer pain and bilateral lower-extremity muscle weakness...

INTRODUCTION: The impact of concomitant urologic procedures (UPs) on perioperative and long-term outcomes after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is uncertain. METHODS: In total, 935 consecutive CRS/HIPEC procedures were performed between 1996 and 2016 in Sydney, Australia. Among these, 73 (7.8%) involved concomitant UP. The association of concomitant UP with 21 perioperative outcomes and overall survival was assessed using univariate and multivariate analyses...

Background: Prostatic carcinoma carries a high morbidity and mortality if it is not diagnosed early. In resource limited countries, patients are at increased risk of being diagnosed late as they are operated for presumed benign prostatic hyperplasia. The information on the magnitude and risk factors of this problem in our setting could assist in the overall optimization of care of patients at risk. Methods: A retrospective study of patients who underwent prostatectomy for presumed benign prostatic enlargement was done at Bugando University Hspital in Tanzania...
