Int. braz. j. urol; 46 (2), 2020
ABSTRACT Purpose To evaluate the usefulness of natural killer cell activity (NKA) in diagnosing prostate cancer (PC). Materials and Methods The medical records of patients who underwent transrectal prostate biopsy (TRBx) at Korea University Ansan Hospital between May 2017 and December 2017 were retro...

Densidad de APE en pacientes PI-RADS 3: un parámetro clínico útil para su manejo

Rev. chil. radiol; 25 (4), 2019
Resumen: Objetivo: Analizar las biopsias realizadas en paciente categorizados PIRADS 3 en nuestra institución desde el segundo semestre del año 2016 al primer semestre del año 2018 y describir la correlación de la densidad de PSA con la incidencia de cáncer de próstata. Evaluar el rol de la densida...

Seminal citrate is superior to PSA for detecting clinically significant prostate cancer

Int. braz. j. urol; 45 (6), 2019
ABSTRACT Purpose: To establish whether the citrate concentration in the seminal fluid ([CITRATE]) measured by means of high-resolution nuclear magnetic resonance spectroscopy (1HNMRS) is superior to the serum prostate-specific antigen (PSA) concentration in detecting of clinically significant prostate c...

Detection of clinically significant prostate cancer with PI-RADS v2 scores, PSA density, and ADC values in regions with and without mpMRI visible lesions

Int. braz. j. urol; 45 (4), 2019
ABSTRACT Purpose To determine if PSAD, PSADtz, and ADC values improve the accuracy of PI-RADS v2 and identify men whose concurrent systematic biopsy detects clinically significant cancer on areas without mpMRI visible lesions. Materials and methods Single reference-center, cross-sectional, retrospecti...

Niveles Plasmáticos de Citoquinas Proinflamatorias en Cáncer de Próstata

Rev. méd. Maule; 34 (1), 2019
INTRODUCTION: Prostate cancer has become an important public health problem affecting millions of men worldwide every year. Like other malignant tumors, prostate cancer shows evidence of a strong inflammatory component that is dependent on the release of pro-inflammatory cytokines, which might play a maj...

Prostate cancer screening in low- and middle- income countries: the Mexican case

Salud pública Méx; 61 (4), 2019
Abstract: Prostate-specific antigen (PSA)-based early detection for prostate cancer is the subject of intense debate. Implementation of organized prostate cancer screening has been challenging, in part because the PSA test is so amenable to opportunistic screening. To the extent that access to cancer scr...

A continuous fall of PSA use for prostate cancer screening among Brazilian doctors since 2001. Good or bad notice?

Int. braz. j. urol; 45 (3), 2019
ABSTRACT Purpose: To evaluate the trend of use of Prostate Specific Antigen (PSA) for screening of prostate cancer (PC) among Brazilian doctors, from the beginning of its regular availability in clinical laboratories. Material and Methods: A serial cross-sectional study was performed using data obtaine...

Role of native thiol, total thiol and dynamic Disulphide in diagnosis of patient with prostate cancer and prostatitis

Int. braz. j. urol; 45 (3), 2019
ABSTRACT Background: Our study investigates whether Native Thiol, Total Thiol and disulphide levels measured in serum of patients with prostate cancer and prostatitis and of healthy subjects, have any role in differential diagnosis. Materials and Methods: Patients followed up for histopathologically ve...

Role of Adiponectin in prostate cancer

Int. braz. j. urol; 45 (2), 2019
ABSTRACT Obesity is defined as a chronic and excessive growth of adipose tissue. It has been associated with a high risk for development and progression of obesity-associated malignancies, while adipokines may mediate this association. Adiponectin is an adipose tissue-derived adipokines, with significant...

Prognosis of patients with prostate cancer and middle range prostate - specific antigen levels of 20 - 100 ng / mL

Int. braz. j. urol; 45 (1), 2019
ABSTRACT Introduction: Prostate - specific antigen (PSA) is a useful biomarker for detection of prostate cancer (PCa) and for risk classification in addition to TNM classification and Gleason score (GS). We reported the role of PSA in patients with low (< 20 ng / mL) and extremely high (≥ 100 n...
