Myoepithelial carcinoma (MECA) is an underrecognized rare tumor with a diverse clinical behavior. The histologic features of this tumor are not well characterized, much less its grading, which is controversial. The objective of this study is to provide a better characterization of MECA and its prognostic factors. A total of 48 cases were retrieved from the(More)
PURPOSE To evaluate the length of capsular contact of dominant lesions on multiparametric prostate magnetic resonance imaging (MRI) for predicting extraprostatic extension (EPE) and to determine a threshold value to apply in clinical practice. MATERIALS AND METHODS Ninety patients undergoing 3T prostate MRI before prostatectomy were included. Two(More)
Prostate cancer (PCa) often presents as a multifocal disease with heterogeneity in Gleason score (GS) and genetic alterations. Dominant/index tumor nodule (DN), the largest nodule in a multifocal disease, is presumed to harbor the most aggressive biological behavior and therefore dictate the overall clinical behavior of PCa. In this study, we examined the(More)
AIM To assess impact of haemorrhage and delay after biopsy on prostate tumour detection using multi-parametric (MP) magnetic resonance imaging (MRI) assessment. MATERIALS AND METHODS Forty-four patients underwent prostate MRI at 1.5 T using a pelvic phased-array coil, including T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), diffusion-weighted(More)
IMPORTANCE Soy consumption has been suggested to reduce risk or recurrence of prostate cancer, but this has not been tested in a randomized trial with prostate cancer as the end point. OBJECTIVE To determine whether daily consumption of a soy protein isolate supplement for 2 years reduces the rate of biochemical recurrence of prostate cancer after radical(More)
BACKGROUND Gaucher disease (GD) is a genetic disease caused by mutations in the GBA1 gene which result in reduced enzymatic activity of β-glucocerebrosidase (GCase). This study identified the progranulin (PGRN) gene (GRN) as another gene associated with GD. METHODS Serum levels of PGRN were measured from 115 GD patients and 99 healthy controls, whole GRN(More)
Sinonasal mucosal melanomas (SNMM) of the head and neck regions are rare and aggressive malignancies. Although they can affect patients of any ethnicity, they are more numerous in Chinese patients. The diagnosis and treatment of these tumors can be challenging. Recent studies have reported that Sox10 is a sensitive melanocytic marker for cutaneous melanoma(More)
OBJECTIVE To study the histopathology changes and clinical features of vesical diverticula, focusing on the neoplastic entities. MATERIALS AND METHODS We retrieved data for 108 patients with vesical diverticula from the archives of our institute during the past 15 years (1998 to 2012) and reviewed their clinical and pathologic characteristics. RESULTS(More)
A modified Gleason grading system as proposed in the 2005 International Society of Urological Pathology (ISUP) consensus meeting is the current grading system for prostate cancer. With this modified ISUP Gleason grading system, many Gleason score (GS) 6 cancers by the old grading system are upgraded to GS7 cancers on biopsy diagnosis even with minimal(More)
RATIONALE AND OBJECTIVES The aim of this study was to assess prostate cancer detection using a broad range of computed b-values up to 5000 s/mm(2). MATERIALS AND METHODS This retrospective Health Insurance Portability and Accountability Act-compliant study was approved by an institutional review board with consent waiver. Forty-nine patients (63 ± 8(More)
