CONTEXT In 2005, the International Society of Urologic Pathology consensus conference recommended that men with biopsy Gleason score 3 + 4 or 4 + 3 prostate cancer and tertiary pattern 5 should have their cancer classified as Gleason score 8 or 9, respectively. Yet, the management of men with Gleason score 7 vs 8 or 9 prostate cancer differs. OBJECTIVE To compare the prognostic significance o...

OBJECTIVE The objective of our study was to determine the relationship between the apparent diffusion coefficient (ADC) value on diffusion-weighted imaging (DWI) and Gleason score of prostate cancer and percentage of tumor involvement on prostate core biopsy. MATERIALS AND METHODS We performed a retrospective study of 57 patients with biopsy-proven prostate cancer who underwent endorectal MRI...

We study the exact observability of systems governed by the Schrödinger equation in a rectangle with homogeneous Dirichlet (respectively Neumann) boundary conditions and with Neumann (respectively Dirichlet) boundary observation. Generalizing results from Ramdani, Takahashi, Tenenbaum and Tucsnak (2005), we prove that these systems are exactly observable in in arbitrarily small time. Moreover, ...

Our aim was to study the level of interobserverconcordance in the Gleason scores of prostate needlebiopsy specimens reported at 1 institution. Aretrospective review of all prostate needle biopsyspecimens in which a diagnosis of adenocarcinoma wasmade during the year 2000 was conducted. Parametersevaluated included the Gleason score, Gleason gradesidentified, the perc...

Abstract An existing preoperative nomogram predicts the probability of prostate cancer recurrence, defined by prostate-specific antigen (PSA), at 5 years after radical prostatectomy based on clinical stage, serum PSA, and biopsy Gleason grade. In an updated and enhanced nomogram, we have extended the predictions to 10 years, added the prognostic information of systematic biopsy results, and ena...

Objective: To investigate the correlation between postoperative pathologic grade of prostate cancer (PC) and preoperative serum PSA as well as grade of biopsy specimens. Methods: The serum PSA and preoperative and postoperative Gleason scores of PC were retrospectively analyzed in 75 patients. Correlation between serum PSA and postoperative Gleason score was evaluated, and the Gleason score bef...

PURPOSE To investigate the role of low dose rate (LDR) brachytherapy-based multimodal therapy in high-risk prostate cancer (PCa) and analyze its optimal indications. MATERIALS AND METHODS We reviewed the records of 50 high-risk PCa patients [clinical stage ≥ T2c, prostate-specific antigen (PSA) >20 ng/mL, or biopsy Gleason score ≥ 8] who had undergone 125I LDR brachytherapy since April 2007. ...

Abstract The main aim of this work is to discuss several different approaches the celebrated Kahane–Salem–Zygmund inequalities. In particular, we prove estimates for exponential Orlicz norms averages $$\sup _{1\le j\le N}\Big |\sum _{i=1}^K a_i(j) \gamma _i\Big |\,,$$ sup 1 ...
