Background: Water vapor thermal therapy (Rezum) is a minimally invasive treatment for benign prostatic enlargement (BPE). Studies reporting urodynamic results regarding the procedure are rare. Our study aimed to assess the effectiveness of Rezum on urinary outcome parameters in a consecutive series of patients and compare urodynamic data before and after treatment.

Tumor Associated Calcium Signal Transducer 2 (TACSTD2) participates in cell cycle progression through MAPK signalling pathway activation. Moreover, tumor-specific hypermethylation and association with aggressive cancer characteristics has been found for lung adenocarcinoma, hepatocellular carcinoma and cholangiocarcinoma.

Patients And Methods: We analyzed 55 HRT patients irradiated with the total dose of 60 Gy in 20 fractions delivered over 4 weeks. These patients were compared to a control group of 55 patients who received CRT with a total of <78 Gy in 37-39 fractions delivered over circa 8 weeks.
Objectives: We had previously demonstrated changes in defecation after radical cystectomy (RC). Reports addressing long-term bowel disorders following RC are rare. This cross-sectional study evaluates long-term bowel issues in a large cohort.

Purpose: [Ga]Tris(hydroxypyridinone)(THP)-PSMA is a novel radiopharmaceutical for one-step kit-based radiolabelling, based on direct chelation of Ga at low concentration, room temperature and over a wide pH range, using direct elution from a Ge/Ga-generator. We evaluated the clinical detection rates of [Ga]THP-PSMA PET/CT in patients with biochemically recurrent prostate cancer after prostatectomy.
Methods: Consecutive patients (n=99) referred for evaluation of biochemical relapse of prostate cancer by [Ga]THP-PSMA PET/CT were analyzed retrospectively.
A quantitative imaging biomarker is desirable to provide a comprehensive measure of whole-body tumor burden in patients with metastatic prostate cancer, and to standardize the evaluation of treatment-related changes. Therefore, we evaluated whether prostate-specific membrane antigen (PSMA) ligand PET/CT may be applied to provide PSMA-derived volumetric parameters for quantification of whole-body tumor burden. One hundred one patients who underwent Ga-PSMA I&T PET/CT because of increasing prostate-specific antigen (PSA) levels after radical prostatectomy were included in this retrospective analysis.

Patients And Methods: Twenty-three patients received radiotherapy for PSMA ligand-positive lymph node metastases.
Results: The median follow-up time was 12.
Purpose: The aim of this study was to assess the value of dual-time point imaging in PET/CT for detection of biochemically recurrent or persistent prostate cancer, using the prostate-specific membrane antigen (PSMA) ligand [Ga]PSMA I&T.
Methods: 240 patients who underwent a [Ga]PSMA I&T PET/CT in the context of biochemical relapse of prostate cancer were included in this retrospective analysis. Imaging consisted of a standard whole-body PET/CT (1 h p.
Purpose: The aims of this study were to gain mechanistic insights into prostate cancer biology using dynamic imaging and to evaluate the usefulness of multiple time-point Ga-prostate-specific membrane antigen (PSMA) I&T PET/CT for the assessment of primary prostate cancer before prostatectomy.
Methods: Twenty patients with prostate cancer underwent Ga-PSMA I&T PET/CT before prostatectomy. The PET protocol consisted of early dynamic pelvic imaging, followed by static scans at 60 and 180 minutes postinjection (p.
A range of new treatment options has recently become available for patients with advanced metastatic castration-resistant prostate cancer (mCRPC). Androgen deprivation therapy (ADT) with luteinizing hormone-releasing hormone is continued when performing chemotherapy or androgen deprivation with new second-generation therapeutic agents such as enzalutamide or abiraterone acetate. Despite the fact that free testosterone (FT) is the biologically active form, it is common practice that androgen suppression is monitored via total testosterone levels only.
View Article and Find Full Text PDFAndrogen deprivation therapy (ADT) is well established as a backbone therapy for metastatic prostate cancer (mPCa), and both European and American guidelines emphasize the importance of maintaining ADT after progression to metastatic castration-resistant prostate cancer (CRPC). However, the use of ADT varies widely in clinical practice despite these recommendations. Both research and development of increasingly precise assay technologies have improved our understanding of androgen production and signaling, and the recent data have suggested that a new serum testosterone cutoff value of <0.

However, prostate biopsy underestimates final pathology in about one-third of patients. We evaluated the final whole gland pathology from radical prostatectomy exclusively in order to assess the true risk of progressing to the mCRPC state for patients with confirmed Gleason ≤6 prostate cancer.

Patients And Methods: A total of 29 patients with biochemical recurrence received a (68)Ga-PSMA ligand PET/CT for restaging of disease, followed by 3D conformal radiotherapy of metastases or intensity-modulated radiation therapy of the prostate bed. Prostate-specific antigen (PSA) levels and imaging procedures served as the reference standard to assess the treatment efficacy.
Introduction: Advanced renal cell carcinoma (RCC) shows a propensity for extending into the tributaries of the renal veins, which poses a notable surgical challenge. In this study we addressed the question as to whether patients with RCC and vein involvement can be identified as having a significant risk of immediate death associated with surgery preoperatively.
Materials And Methods: A total of 118 patients with RCC and vein involvement from February 1999 until November 2012 were evaluated.
Purpose: En bloc resection of bladder tumors (ERBT) may improve staging quality and perioperative morbidity and influence tumor recurrence. This study was designed to evaluate the safety, efficacy, and recurrence rates of electrical versus laser en bloc resection of bladder tumors.
Methods: This European multicenter study included 221 patients at six academic hospitals.
Enzalutamide is an oral androgen receptor inhibitor that targets multiple steps in the androgen receptor signaling pathway. In the randomized phase III AFFIRM study, significant improvements in survival versus placebo were observed when enzalutamide was used as a treatment for patients with metastatic castration-resistant prostate cancer (mCRPC) following prior treatment with docetaxel. Additional benefits included significant delay in time to first skeletal-related event, and improvement in several measures of pain and health-related quality of life.

View Article and Find Full Text PDFGATA-binding proteins 1 (GATA1) and 2 (GATA2) are zinc-finger transcription factors and belong to the GATA family proteins 1-6. GATA1 interacts with the TP53 tumor suppressor gene, and both GATAs have been shown to be involved in cell growth, apoptosis, and tumorigenesis of several solid tumors. GATA1 and GATA2 expression alterations are associated with poor survival and adverse clinicopathology in prostate and colorectal cancer, while the significance and prognostic value in clear cell renal cell carcinoma (ccRCC) has not been investigated as yet.

Design, Setting, And Participants: Metastatic castration-resistant prostate cancer patients entering one of four European compassionate use programmes of enzalutamide.
Background: Nephron sparing surgery for renal tumors has evolved as the standard of care for resectable renal tumors. Laparoscopic partial nephrectomy (PN) has gained recognition after technical refinements were able to match the well-established criteria for open partial nephrectomy. Laparoendoscopic surgery (LESS) is one of the approaches to further minimize invasiveness of laparoscopic surgery.
