To retrospectively evaluate the imaging quality of diffusion-weighted (DWI), compare apparent diffusion coefficient (ADC) values for malignant and benign tissues in peripheral zone (PZ) transition (TZ), whether T2-weighted (T2WI) with DWI could improve prediction prostate cancer location when compared T2WI at 3T using a phased-array coil.Thirty-seven patients underwent before radical prostatectomy. The technique b = 0 1000 s/mm2 was used. ADC were measured PZ or TZ. evaluated TZ DWI,...
To prospectively evaluate the incremental value of diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) maps in addition to T2-weighted (T2WI) for predicting locally recurrent prostate cancer patients biochemical failure after radiation therapy.Thirty-six consecutive an increased prostate-specific antigen level therapy underwent 3T MRI followed by transrectal biopsy. The findings and biopsy results were correlated sextant sectors peripheral zones (PZs). Two radiologists...
The purpose of our study was to prospectively evaluate whether MRI before an initial transrectal ultrasound-guided biopsy contributed detection prostate cancer in patients with high prostate-specific antigen (PSA) level and no previous biopsy.Men abnormal digital rectal examination or PSA were enrolled this prospective randomized study. Participants randomly allocated into two groups; the group underwent 3-T then a knowledge location. non-MRI did not undergo biopsy. rate positive core...
Resistance of bladder cancer to cisplatin is a major obstacle successful treatment. In the current study, we investigated apoptotic effects curcumin and co-treatment in 253J-Bv(p53 wild-type) T24(p53 mutant) cancer. We found that primarily targets reactive oxygen species(ROS) extracellular regulated kinase(ERK) signaling during apoptosis induction The rate 253J-Bv T24 cells co-treated with was increased compared exposed single-agent treatment conditions. Also, caspase-3 activation ROS...
Background The anti‐cancer activities of curcumin are well‐documented from preclinical studies using prostate cancer models. Our objective was to evaluate the activity oral in patients with cancer. Methods This randomized, double‐blind, placebo‐controlled trial performed on who received intermittent androgen deprivation (IAD). Participants finished first on‐treatment period IAD were randomized into a or placebo group. took (1440 mg/day) for six months and followed up until beginning second...
To evaluate prospectively the use of apparent diffusion coefficients (ADCs) for differentiation malignant and benign tissue in transition (TZ) peripheral (PZ) zones prostate diffusion-weighted imaging (DWI) at 3 T magnetic resonance (MRI) using a phased-array coil.The DWI 3-T MRI was performed on total 35 patients before radical prostatectomy. A single-shot echo-planar technique with b = 0 1000 s/mm2 used. The ADC values were measured both tissues PZ TZ regions interest. Differences between...
OBJECTIVES To evaluate the role of 18 F‐fluorodeoxyglucose (FDG) positron‐emission tomography (PET)/computed (CT) for surveillance patients with renal cell carcinoma (RCC) who have a high risk local recurrence or distant metastasis, by comparing results those conventional imaging methods. PATIENTS AND METHODS Sixty‐three RCC had studies and FDG PET/CT during follow‐up after surgical treatment. Their pathological stages were T2 in 28 patients, T3a 14, T3b 19 T4 two; lymph‐node metastases...

Objective: To retrospectively evaluate local staging accuracy for prostate cancer at 3.0-T magnetic resonance imaging (MRI) by comparing with that 1.5-T MRI. Methods: Two groups, each consisting of 54 patients, were included matching age, specific antigen, and Gleason score. Before radical prostatectomy, 1 group underwent MRI using a phased-array coil, the other an endorectal coil. T2-weighted MR images 3.0 1.5 T analyzed in consensus 2 radiologists, their was compared histology. Artifact...
We evaluated the accuracy of preoperative multiparametric 3.0-T magnetic resonance imaging for local staging prostate cancer and its influence in decision to preserve neurovascular bundles at robotic assisted laparoscopic radical prostatectomy.The study included 353 patients who had confirmed underwent prostatectomy between 2008 2011. The extent bundle sparing was initially determined on basis clinical information nerve surgical plan reevaluated after review report. value prediction...

Objective: To assess the use of diffusion-weighted imaging (DWI) at 3 Tesla (T) for lesion localization in patients with a high risk prostate cancer before rebiopsy. Materials and Methods: A total 43 (age range, 40–80 years; mean age, 62.6 years) who had previously undergone transrectal ultrasound (TRUS)-guided biopsy that was negative continued to have persistent elevated specific antigen level underwent DWI b = 0 s/mm2 1000 We located area lowest apparent diffusion coefficient values...
Abstract Purpose: The increasing prevalence of distant metastases from non–small cell lung cancer (NSCLC) indicates an urgent need for novel therapeutic modalities. Brain metastasis is particularly common in NSCLC, with severe adverse effects on clinical prognosis. Although the molecular heterogeneity NSCLC and availability various targeted agents suggest personalized approaches such brain metastases, further development appropriate preclinical models needed to validate strategies....
Purpose: To compare percutaneous radiofrequency ablation (RFA) and open partial nephrectomy (OPN) for the treatment of renal cell carcinoma (RCC) with respect to function mid-term oncological outcome.Materials methods: From January 2006 December 2008, 40 (RFA group) 110 (OPN patients underwent RFA OPN sporadic RCC, respectively. The sizes locations RCCs were matched between two groups. determine lesion size, maximum transverse diameter was measured. Estimated glomerular filtration rates...
The purpose of this study is to retrospectively investigate whether pretreatment multiparametric MRI findings can predict biochemical recurrence in patients who underwent radical prostatectomy (RP) for localized prostate cancer.In study, 282 with biopsy-proven cancer received RP using a phased-array coil at 3 T, including T2-weighted imaging (T2WI), diffusion-weighted (DWI), and dynamic contrast-enhanced (DCE-MRI). variables included apparent tumor presence on combined sequences,...
Diagnostic ureterorenoscopy is powerful tool to confirm upper tract urothelial cancer (UTUC). However, URS and associated manipulation may be related the risk of intravesical recurrence (IVR) following radical nephroureterectomy (RNU). We aimed investigate whether preoperative would increase IVR after RNU in patients with UTUC. performed a retrospective analysis 630 who had bladder cuff excision due was 282 (44.7%). Patients were divided into two groups according URS. Survival multivariate...
