Predicting Gleason Scores of Prostate Cancer Using Combined Trace Apparent Diffusion Coefficient and Tumor Volume
Introduction With increasing life expectancy, prostate cancer (PCA) is becoming one of the most common forms of malignancy in men. Clinically, the Gleason Scores (GS) are commonly used to assess the aggressiveness of PCA with grades from 1 to 5. The GS is one of the parameters in a strategy of staging system that predicts prognosis and helps decision of treatment options. Magnetic resonance (MR...
متن کاملProstate MRI: evaluating tumor volume and apparent diffusion coefficient as surrogate biomarkers for predicting tumor Gleason score.
PURPOSE To investigate whether tumor volume derived from apparent diffusion coefficient (ADC) maps (VolumeADC) and tumor mean ADC value (ADCmean) are independent predictors of prostate tumor Gleason score (GS). EXPERIMENTAL DESIGN Tumor volume and GS were recorded from whole-mount histopathology for 131 men (median age, 60 years) who underwent endorectal diffusion-weighted MRI for local stagi...
متن کاملProstate cancer: apparent diffusion coefficient map with T2-weighted images for detection--a multireader study.
PURPOSE To retrospectively assess the incremental value of an apparent diffusion coefficient (ADC) map combined with T2-weighted magnetic resonance (MR) images compared with T2-weighted images alone for prostate cancer detection by using a pathologic map as the reference standard. MATERIALS AND METHODS This retrospective study was approved by the institutional review board; informed consent w...

Purpose To investigate whether tumor volume derived from apparent diffusion coefficient (ADC) maps (VolumeADC) and tumor mean ADC value (ADCmean) are independent predictors of prostate tumor Gleason score (GS). Materials and Methods Tumor volume and GS were recorded from whole-mount histopathology for 131 men (median age, 60) who underwent endorectal diffusion-weighted magnetic resonance imagin...
متن کاملApparent diffusion coefficient on magnetic resonance imaging (MRI) in bladder cancer: relations with recurrence/progression risk.
AIMS To evaluate the relationship between the apparent diffusion coefficient (ADC) value for bladder cancer and the recurrence/progression risk of post-transurethral resection (TUR). METHODS Forty-one patients with initial and non-muscle-invasive bladder cancer underwent MRI from 2009 to 2012. Two radiologists measured ADC values. A pathologist calculated the recurrence/progression scores, an...
