BERKELEY, CA (UroToday.com) - Accurate urinary assays for bladder cancer (BCa) detection would benefit both patients and healthcare systems. Through genomic and proteomic profiling of urine components, we have previously identified a panel of biomarkers that can outperform current urine-based biomarkers for the non-invasive detection of BCa. Herein, we report the diagnostic utility of various multivariate combinations of these biomarkers.

Clear cell renal cell carcinoma (ccRCC) is the most common type among renal cell carcinomas, and anti-angiogenic treatment is currently first line therapy in metastatic ccRCC (mccRCC). Response rates and duration of response show considerable variation, and adverse events have major influence on patient's quality of life.

Prostate Specific Antigen (PSA) fails to discriminate between benign prostatic hyperplasia (BPH) and Prostate Cancer (PCa), resulting in large numbers of unnecessary biopsies and missed cancer diagnoses.

Prostate specific antigen (PSA) test is the most common, clinically validated test for the diagnosis of prostate cancer (PCa). While neoplastic lesions of the prostate may cause aberrant levels of PSA in the blood, the quantitation of free or complexed PSA poorly discriminates cancer patients from those developing benign lesions, often leading to invasive and unnecessary surgical procedures.

The alkaline phosphatase-streptavidin (AP-SA) probe released adenosine (∼267.2 Da) from the substrate adenosine monophosphate, where a signal may be detected from as little as 0.5 micro litres of a 0.

Procoagulant activity attributed to tissue factor (TF, CD142) bound to lipid microvesicles has previously been shown to be elevated in urine of patients with various solid cancers. The phosphorylation of the C-terminal signal transduction peptide (STP) at Ser253 and Ser258 has been determined to be important for the formation of TF-microvesicles.
