Early detection and screening for prostatic cancer

Abstract

In the past thirty years, the mortality rate from prostate cancer has not declined. This is due in part to the small number of tumors diagnosed while they are still curable by surgery or radiation. Recent studies have demonstrated that transrectal sonography can detect nonpalpable tumors, which are usually potentially curable. As a result, some physicians now recommend routine screening of all men over age fifty. The main goal of a cancer screening test is to help reduce mortality. To date, it has been shown that screening can increase early detection and survival, but there is no experimental evidence that screening reduces mortality. Therefore, screening for prostate cancer may not be worthwhile. The large number of prostate tumors found on autopsy series indicates that only a small fraction of patients with prostate cancer actually die of it. The risk of screening is that many insignificant tumors may be diagnosed and patients may be treated unnecessarily, resulting in significant morbidity, mortality, and expense. For now, it may be appropriate to let patients choose whether or not to have the test performed, after informing them screening can increase early detection, but could also result in overdiagnosis and treatment.

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
