Abstract

Annual national epidemiological evaluation of renal tumours by means of a multicentre survey proposed by the oncology committee of the Association Française d'Urologie. From April 1, 1993 to March 31, 1994, 970 patients were recruited by 54 centres. A computer form was completed for each patient, including: the patient's age and sex, modalities of discovery of the tumour, complementary investigations (radiological and laboratory tests) performed, treatment performed, TNM staging, histological characteristics of the tumour. The mean age of the patients was 62.1 years with a sex ratio of 2 males to 1 female. The rate of incidental tumours was 40%. Radical nephrectomy was performed in 90% of cases and conservative surgery was performed in 7% of cases. Medical treatment was instituted in 5% of cases. The distribution of tumours by TNM stage was: pT1: 8%, pT2: 53%, pT3a: 21% and pT3b: 18%. Lymph node involvement was detected in 12% of cases, and visceral metastases were identified in 6% of cases. 80% of incidental tumours were intracapsular. The predominant histological type was renal cell carcinoma (66%). The mean tumour size for the entire series of tumours was 6.4 +/- 3.5 cm and was significantly larger in symptomatic patients 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.
