Management of localized prostate cancer: an epidemiological perspective

Clinical Oncology : a Journal of the Royal College of Radiologists
R H Harwood

Abstract

Prostate cancer is an important and increasing source of male morbidity and mortality. In the absence of any primary preventative strategy, medical approaches to control it will concentrate on attempts at cure in localized disease and effective palliation otherwise. Observational epidemiological studies suggest that, in practice, differences in the effectiveness of aggressive and conservative approaches will be small, but may yet be worthwhile in selected groups of men. However, the confounding and biases inherent in all observational epidemiology mean that the data available from this source is insufficiently certain or precise either to make treatment recommendations for individuals, or to quantify relative benefits to inform health policy. Randomized trial data has not suggested any overwhelming benefit for any one treatment modality, but the five published trials have been small and lacked the statistical power to demonstrate potentially important differences. Aggressive management aimed at cure should be evaluated in adequately designed randomized trials in comparison with expectant medical management ('watchful waiting'). The trials currently planned or under way should be supported enthusiastically by all centres with an...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.
