Relative value of prostate-specific antigen and prostatic acid phosphatase in diagnosis and management of adenocarcinoma of prostate. Ohio State University experience

J R DragoJ C Neff


Serum concentrations of prostate-specific antigen (PSA), prostate-specific acid phosphatase (PAP), and transrectal prostatic ultrasound were utilized in the evaluation of 193 men with various urologic disorders. Of the 193 patients, 48 had prostate cancer, and the other 145 included 5 with genitourinary neoplasms, 69 with benign prostatic hypertrophy, and 71 with other non-neoplastic genitourinary disease. PSA levels were elevated in 35 patients with prostate cancer and in 25 of the 145 without prostate cancer. PAP levels were elevated in 15 with prostate cancer and in 2 of the 145 without prostate cancer. The data indicate that PSA is a more sensitive but less specific tumor marker than PAP in the detection of prostate cancer. PSA appears to be more sensitive than PAP in monitoring the response to treatment. The use of PSA and PAP jointly to detect and to monitor prostate cancer did not appear to enhance the clinical utility over that of PSA alone.

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.
