Renal cell carcinoma biomarkers include serum, urine, liquid, and tissue biomarkers. There is currently an ongoing search for predictive biomarkers in the detection, recurrence, and treatment of renal cell carcinoma.
The current definition of urinary tract infection (UTI) relies on laboratory and clinical findings, which may or may not be relevant, depending upon the patient group under consideration. This report considers the utility of current definitions for UTI in adults with and without underlying neurological conditions in order to identify gaps in current understanding and to recommend directions for research.

The measurement of gene expression in post-digital rectal examination (DRE) urine specimens provides a non-invasive method to determine a patient's risk of prostate cancer. Many currently available assays use whole urine or cell pellets for the analysis of prostate cancer-associated genes, although the use of extracellular vesicles (EVs) has also recently been of interest.

This study aimed to systematically review evidence on the diagnostic performance of biomarkers which might be suitable for use in community and primary care settings [PROSPERO Registration: CRD42021258754].
Due to insufficient accuracy, urine-based assays currently have a limited role in the management of patients with bladder cancer. The identification of multiplex molecular signatures associated with disease has the potential to address this deficiency and to assist with accurate, non-invasive diagnosis and monitoring.
Prostate cancer, the second most frequently diagnosed cancer in males worldwide, is estimated to be diagnosed in 1.1 million men per year. Introduction of PSA testing substantially improved early detection of prostate cancer, however it also led to overdiagnosis and subsequent overtreatment of patients with an indolent disease.
Contactin 1 (CNTN1) is a new oncogenic protein of prostate cancer (PC); its impact on PC remains incompletely understood. We observed CNTN1 upregulation in LNCaP cell-derived castration-resistant PCs (CRPC) and CNTN1-mediated enhancement of LNCaP cell proliferation.

Prostate cancer (PCa) is the seventh most diagnosed cancer and the tenth leading cause of cancer mortality in China. Unlike the USA, both incidence and mortality continue to increase. In China, PCa is often diagnosed at a locally advanced or metastatic stage, resulting in a high mortality-to-incidence ratio.

We explore the mechanism of action of microRNAs, literature to date, and how microRNAs may be incorporated into clinical practice in the near future.
Prostate cancer (PCa) is the second most common cancer amongst men in the United States. While the use of PSA has improved the ability to screen and ultimately diagnose PCa, there still remains false positives due to non-cancerous conditions in the prostate gland itself and other prognostic biomarkers for PCa are needed.
Advanced urothelial carcinoma (aUC) has long been treated preferably with cisplatin-based chemotherapy, but many patients are cisplatin-ineligible whereas for those who progress on a platinum-based regimen treatment options are limited.
Urothelial bladder cancer is one of the first cancers recognized to be immunogenic since 40 years ago when the use of bacillus Calmette-Guerin was shown to prevent recurrence. Since that time, our knowledge of immune biology of cancer has expanded tremendously, and patients with bladder cancer finally have new active immunotherapeutic drugs on the horizon.
Non-muscle invasive bladder cancer (NMIBC) accounts for 70-75% of all bladder cancers and is a heterogeneous disease characterized by a wide spectrum of recurrences and progression. Adjuvant treatment for intermediate- and high-risk NMIBC is mainly represented by Bacillus Calmette Guerin (BCG).
Prostate cancer continues to be a major cause of morbidity and mortality in men, but a method for accurate prognosis in these patients is yet to be developed. The recent discovery of altered endosomal biogenesis in prostate cancer has identified a fundamental change in the cell biology of this cancer, which holds great promise for the identification of novel biomarkers that can predict disease outcomes.
