Abstract

We assessed the value of preoperative levels of CEA, CA-125 or CA 19-9 in patients with clinically organ confined bladder cancer to predict pathological extravesical and/or node positive disease. Serum levels of CEA, CA-125 and CA 19-9 were measured prospectively in all patients scheduled for cystectomy for clinically organ confined bladder cancer between September 1999 and May 2004. Biomarker expression was compared between patients with pathologically organ confined disease (pT2 or less, pN0) and patients with extravesical disease (greater than pT2, or pN1 or greater), and between patients with pathologically node negative (any pT, pN0) and node positive disease (any pT, pN1 or greater). Of the 91 patients enrolled, 46 had (51%) pathologically organ confined tumors, 45 (49%) had extravesical disease and 17 (19%) had positive lymph nodes. Preoperative serum levels of all markers were significantly higher in cases of extravesical disease than in organ confined disease. On multivariate analysis CEA with an odds ratio of 8.6 (95% CI 1.51-48.6) and CA-125 with an OR of 29.5 (95% CI 3.6-242.6) proved independent predictors of extravesical disease. CA-125 and CA 19-9 levels were significantly higher in patients with node positive di...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
