Clinical significance of serum high sensitive C-reactive protein/albumin ratio in primary prostate biopsy.

Objective: The purpose of this study was to investigate the clinical significance of serum high sensitive C-reactive protein/albumin ratio in primary prostate biopsy.

Methods: Retrospective analysis was done on the clinical data of 1679 patients who had their first transrectal or perineal prostate biopsy at our situation from 2010 to 2018. Prostate cancer (PCa) and benign prostatic hyperplasia (BPH) were the pathologic diagnoses in 819 and 860 cases, respectively.

Texture analysis based on PI-RADS 4/5-scored magnetic resonance images combined with machine learning to distinguish benign lesions from prostate cancer.

Background: The global morbidity and mortality of prostate cancer (PCa) increase sharply every year. Early diagnosis is essential; it determines survival and outcome. So, this study extracted the texture features of apparent diffusion coefficient images in multiparametric magnetic resonance imaging (mp-MRI) and built machine learning models based on radiomics texture analysis (TA) to determine its ability to distinguish benign from PCa lesions using the Prostate Imaging Reporting and Data System (PI-RADS) 4/5 score.

Single-Cell Genomics-Based Molecular Algorithm for Early Cancer Detection.

As one of the prime applications of liquid biopsy, the detection of tumor-derived whole cells and molecular markers is enabled in a noninvasive means before symptoms or hints from imaging procedures used for cancer screening. However, liquid biopsy is not a diagnostic test of malignant diseases because it fails to establish a definitive cancer diagnosis. Although single-cell genomics provides a genome-wide genetic alternation landscape, it is technologically challenging to confirm cell malignancy of a suspicious cell in body fluids due to unknown technical noise of single-cell sequencing and genomic variation among cancer cells, especially when tumor tissues are unavailable for sequencing as the reference.

Development of a highly sensitive digital PCR assay to quantify long non-coding RNA in urine samples which exhibited great potential as an alternative diagnostic biomarker for prostate cancer.

Background: The diagnostic methods of prostate cancer (PCa) present major drawbacks in that serum prostate specific antigen (PSA) testing lacks specificity for PCa and prostate needle biopsy is a painful and highly invasive procedure for patients. Thus, new alternative screening methods which are specific and non-invasive both in the early detection and in the clinical definitive diagnosis of PCa are in urgent need. Long non-coding RNA has been shown to promote PCa cell proliferation and migration, and is significantly upregulated both at the cellular and tumor tissue level.

Comparison of Retzius-Sparing Robot-Assisted Radical Prostatectomy vs. Conventional Robot-Assisted Radical Prostatectomy: An Up-to-Date Meta-Analysis.

The Retzius space-sparing robot-assisted radical prostatectomy (RS-RARP) has shown better results in urinary continence, but its efficacy and safety compared to conventional robot-assisted radical prostatectomy (c-RARP) remain controversial. A research was conducted in Medline PubMed, Cochrane Library, EMBASE, and Web of Science up to January 4, 2021, to identify studies comparing RS-RARP to c-RARP. We used RevMan 5.

Laparoscopic radical resection for large-volume renal carcinoma: via retroperitoneal or transperitoneal approach?

Purpose: The aim of this study was to investigate the clinical efficacy and safety of laparoscopic radical resection through retroperitoneal and transperitoneal approaches in treating large-volume renal carcinoma.

Methods: A total of 116 patients with large-volume (>7 cm) renal carcinoma underwent laparoscopic radical resection for renal carcinoma. Among them, 58 were treated through retroperitoneal approach (Retroperitoneal group), and 58 were treated through transperitoneal approach (Abdominal group).

Clinical association between pre-treatment levels of plasma fibrinogen and bone metastatic burden in newly diagnosed prostate cancer patients.

Background: Due to the different treatments for low-volume metastatic prostate cancer (PCa) as well as high-volume ones, evaluation of bone metastatic status is clinically significant. In this study, we evaluated the correlation between pre-treatment plasma fibrinogen and the burden of bone metastasis in newly diagnosed PCa patients.

Methods: A single-center retrospective analysis, focusing on prostate biopsies of newly diagnosed PCa patients, was performed.

PSCA rs1045531 Polymorphism and the Risk of Prostate Cancer in a Chinese Population Undergoing Prostate Biopsy.

Background And Purpose: This study explored the association between a single-nucleotide polymorphism of prostate stem cell antigen and prostate cancer in Chinese patients undergoing prostate biopsy.

Materials And Methods: DNA from 416 patients undergoing prostate biopsy was typed for the prostate stem cell antigen rs1045531 single-nucleotide polymorphism. The frequency of the rs1045531 polymorphism in patients with prostate cancer and in patients with benign prostatic hyperplasia was compared.

Resistive index of prostatic capsular arteries as a predictor of prostate cancer in patients undergoing initial prostate biopsy.

To evaluate the value of resistive index (RI) of prostatic capsular arteries in diagnosis and evaluation of prostate cancer (PCa) in Chinese patients undergoing initial prostate biopsy. A total of 532 consecutive patients undergoing prostate biopsy were enrolled in this study. RI was measured on the largest transverse section of prostate for each individual.

E-cadherin gene promoter hypermethylation may contribute to the risk of bladder cancer among Asian populations.

There are increasing scientific evidences suggesting that E-cadherin gene promoter hypermethylation may contribute to the development and progression of bladder cancer, but existing studies have yielded inconclusive results. This meta-analysis aims to assess the role of E-cadherin promoter hypermethylation in bladder carcinogenesis. We conducted an extensive literature search for relevant studies on PubMed, Embase, Web of Science, Cochrane Library, and CBM databases from their inception through May 1st, 2013.
