OBJECTIVE: Noncoding RNAs play an important role in carcinogenesis; a number of tRNA-halves are expressed in response to androgen stimulation and are involved in prostate cancer (CaP) initiation and progression. In this study, we evaluated the expression profile of androgen-dependent tRNA-halves in CaP. MATERIALS AND METHODS: Total RNA was isolated from formalin-fixed paraffin-embedded 58 CaP, and 25 benign prostate hyperplasia tissues. We also studied the expression in serum from 49 localized and 21 metastatic castration-resistant CaP samples...

BACKGROUND: Prostate-specific antigen screening for prostate cancer (CaP) remains controversial. This study establishes the role of microRNA 301a (miR-301a) as a supplemental biomarker that can distinguish between patients with benign prostate hyperplasia and clinically significant CaP. We evaluate the ability of miR-301a to predict the adverse pathology of CaP. METHODS: In the first cohort, serum and prostate tumor samples were obtained from thirteen patients with benign prostatic hypertrophy (BPH), twelve patients with Gleason 6, and sixteen patients with Gleason 7 prostate adenocarcinoma...

INTRODUCTION: Genetic testing has been recently put forth as a strategy to improve decision-making in the management of localized prostate cancer. Little is known about how frequently prostate cancer specialists are using these tests, or whether they consider them important or effective. We performed a national survey of radiation oncologists and urologists on their perceptions and self-reported use of genetic testing. METHODS: From January to July 2017, a 4-wave mail survey was performed involving 915 radiation oncologists and 940 urologists about genetic testing and decision-making for localized prostate cancer...

BACKGROUND: Inhibition of the receptor activator of NF-κB ligand (RANKL) has become a standard of care supportive treatment to prevent skeletal related events in cancer patients. Moreover, RANKL inhibition has been implicated with better survival outcome in lung cancer, while RANKL expression induces tumor progression and metastatic spread in vivo in breast cancer. Whether RANK/RANKL may have an impact on the pathogenesis of clear cell renal cell carcinoma (ccRCC) is currently unknown...

INTRODUCTION: Recent studies have proposed that nearby fat deposits may have metabolic influence on kidney cancer pathobiology. Both fat quantity and quality may play unique roles in this complex relationship. As such, we investigated whether perinephric fat surface area (PFA), a quantitative measure of fat, or Mayo Adhesive Probability (MAP) score, a qualitative measure, were predictive of malignant pathology or Fuhrman grade in small renal masses. METHODS: A total of 317 patients undergoing minimally invasive partial nephrectomy between 2010 and 2016 for renal masses were retrospectively reviewed...

BACKGROUND: AKR1C3, as a crucial androgenic enzyme, facilitates intratumoral androgen biosynthesis and androgen receptor activation in castration-resistant prostate cancer (PCa). The data has shown that AKR1C3 expression is significantly elevated in clinical metastatic PCa specimens, indicating a potential role of AKR1C3 in PCa metastasis. METHODS: C4-2, 22RV1-T, and PC-3 cells with higher AKR1C3 expression were selected and treated with several specific AKR1C3 shRNAs or small molecule inhibitor, and the cell migration and invasion abilities were detected by wound healing assay and Transwell assay...

BACKGROUND: In nonmuscle invasive bladder cancer patients, prediction of pTa and pT1 bladder cancer recurrence and progression must be established. Micropapillary structures have been defined as small clusters of invasive cancer cells having features of the epithelial-mesenchymal transition. Since the stromal microenvironment helps to induce the epithelial-mesenchymal transition, interactions between cancer cells and stroma should be closely examined to predict the tumorigenic phenotype of human bladder cancer cells...

OBJECTIVES: A high body mass index (BMI) is associated with an increased risk for developing renal cell carcinoma (RCC), a higher complication rate after surgery, and a postoperative decline in renal function after nephrectomy. In contrast, a high preoperative BMI has been associated with increased survival in patients with localized RCC. We examined the prognostic impact of the BMI in patients treated for metastatic RCC (mRCC) in daily routine practice in Germany. PATIENTS AND METHODS: The ongoing prospective, multicenter German clinical cohort study on mRCC (RCC-Registry) has recruited patients from more than 110 oncology/urology outpatient centers and hospitals at initiation of systemic first-line treatment...
