With increased industrial utilization of iron oxide nanoparticles (Fe2O3-NPs), concerns on adverse reproductive health effects following exposure have been immensely raised. In the present study, the effects of Fe2O3-NPs exposure in the seminal vesicle and prostate gland were studied in mice. Mice were exposed to two different doses (25 and 50 mg/kg) of Fe2O3-NPs along with the control and analyzed the expressions of heat shock proteins (HSP60, HSP70 and HSP90) and organ specific markers (Caltrin, PSP94, and SSLP1)...

BACKGROUND: The causative role of the pro-inflammatory cytokine IL-6 in prostate cancer progression has been well established at molecular level. However, whether and how IL-6 may play a role in prostate cancer risk and development is not well defined. One limitation factor to acquiring this knowledge is the lack of appropriate animal models. METHODS: We generated a novel line of prostate-specific IL-6 transgenic mouse model. We compared the prostate pathology, tumorigenic signaling components, and prostate tumor microenvironment of the IL-6 transgenic mice with wild type littermates...

OBJECTIVE: Early-stage prostate cancer may be followed with active surveillance to avoid overtreatment. Our institution's active surveillance regimen uses annual MRI in place of serial biopsies, and biopsies are performed only when clinically necessary. The objective of our study was to report the multiparametric MRI characteristics of prostate cancer patients who discontinued active surveillance at our institution after repeat imaging revealed possible evidence of tumor upgrading. MATERIALS AND METHODS: The Department of Urology at Winthrop University Hospital prospectively maintains a database of prostate cancer patients who are monitored with active surveillance...

Maximum androgen blockade is the standard endocrine treatment for advanced prostate cancer. Interstitial lung disease in different degrees of severity, with low mortality and excellent response to treatment may appear with its use. We report a 77 years old patient with advanced prostate cancer who developed severe and progressive respiratory failure associated to bilateral pulmonary infiltrates, attributed to the direct effect of maximum androgen blockade. Despite the therapeutic efforts, the patient died. Lung pathology revealed Usual Interstitial Pneumonia...

The human HOXB13 gene encodes a transcription factor containing a DNA-binding homeobox domain and a HoxA13 N-terminal domain. SNP is considered to be the primary genetic cause for hereditary prostate cancer (PCa). The study of functional nsSNP's would give an insight into the exact cause underlying the onset of hereditary PCa and possible methodologies for the cure or early management of the disease. Several in silico tools were used to screen and map the deleterious nsSNP's to the protein structure for predicting the structure-function effects...

PURPOSE: While Positron Emission Tomography/Computed Tomography (PET/CT) with (68)Ga-PSMA-11 in the diagnosis of prostate cancer (PCa) is routinely performed at 1h post injection (p.i.), later scans may be beneficial since most lesions present with higher uptake and contrast. This evaluation aimed to investigate the clinical impact of additional late (68)Ga-PSMA-11-PET/CT. METHODS: Between 2011 and 2016, 112 patients with PCa who received early (at 1h p.i.) and late (at 3h p...

BACKGROUND: Some studies have reported that deletions at chromosome arm 9p occur frequently and represent a critical step in carcinogenesis of some neoplasms. Our aim was to evaluate the deletion of locus 9p21 and chromosomes 3, 7 and 17 in localized prostate cancer (PC) and correlate these alterations with prognostic factors and biochemical recurrence after surgery. METHODS: We retrospectively evaluated surgical specimens from 111 patients with localized PC who underwent radical prostatectomy...

: Prostate cancer (PCa) is the second most common cancer in men worldwide. Gleason grading is an important predictor of PCa outcomes and is influential in determining patient treatment options. Clinical decisions based on a Gleason score of 7 are difficult as the prognosis for individuals diagnosed with Gleason 4+3 cancer is much worse than for those diagnosed with Gleason 3+4 cancer. Laser capture microdissection (LCM) is a highly precise method to isolate specific cell populations or discrete microregions from tissues...

The human prostate is a gland of the male reproductive tract, which together with the seminal vesicles, is responsible for most seminal fluid production. It is a common site of cancer, and unlike other glands, it typically enlarges in aging men. In flies, the male accessory glands make many major seminal fluid components. Like their human equivalents, they secrete proteins from several conserved families, including proteases, lectins, and cysteine-rich secretory proteins, some of which interact with sperm and affect fertility...

INTRODUCTION: The objective of this study was to evaluate changes of patient characteristics and surgical techniques in radical prostatectomy in Germany within the last decade. METHODS: Data from 44 German prostate cancer centers were included in the study. Patients' characteristics (age, initial PSA value), surgical techniques (open vs. minimally invasive approaches), perioperative parameters (operating time, rate of nerve-sparing (NS) radical prostatectomies (RPs), hospitalization time, catheter indwelling time, surgical margin status, number of dissected lymph nodes (LN)), and pathological findings (tumor stage, Gleason score) were analyzed...

PURPOSE: The lack of biomarkers that can distinguish aggressive from indolent prostate cancer has caused substantial overtreatment of clinically insignificant disease. Here, by genome-wide DNA methylome profiling, we sought to identify new biomarkers to improve the accuracy of prostate cancer diagnosis and prognosis. EXPERIMENTAL DESIGN: Eight novel candidate markers, COL4A6, CYBA, TCAF1 (FAM115A), HLF, LINC01341 (LOC149134), LRRC4, PROM1, and RHCG, were selected from Illumina Infinium HumanMethylation450 BeadChip analysis of 21 tumor (T) and 21 non-malignant (NM) prostate specimens...

Desde que D. F. Gleason creara su sistema en 1966 (1 ) y que él mismo modificó en 1974 (2), su método ha sido universalmente aceptado y recomendado por la OMS (3)como factor pronóstico del carcinoma prostático (CaP). Pero, la generalización de la prueba del PSA a partir de 1979 (4), del desarrollo de la TRUS (5) y de la "biopty-gun" para la toma de biopsias en sextantes en los años 80 (6), y sus posteriores modificaciones, son hechos que han cambiado paulatinamente la postura ante el CaP y, con la experiencia adquirida, algunas de las reglas iniciales de Gleason han evolucionado...

PURPOSE: Tumor localization provides crucial information for radiotherapy dose differentiation treatments, such as focal dose escalation and dose painting by numbers, which aim at achieving tumor control with minimal side effects. Multi-parametric (mp-)MRI is increasingly used for tumor detection and localization in prostate because of its ability to visualize tissue structure and to reveal tumor characteristics. However, it can be challenging to distinguish cancer, particularly in the transition zone...

PURPOSE: Robotics in surgery is a recent innovation. This technology offers a number of attractive features in laparoscopy. It overcomes the difficulties with fixed port sites by restoring all 6 degrees of freedom at the instrument tips, provides new possibilities for miniaturization of surgical tasks and allows remote controlled surgery. We investigated the applicability of remote controlled robotic surgery to laparoscopic radical prostatectomy. MATERIALS AND METHODS: Our previous experience with laparoscopic prostatectomy served as a basis for adapting robotic surgery to this procedure...
