Abstract

Aim of this study was to evaluate the role of radiofrequency ablation in the treatment of the hepatic metastasis of colorectal cancer. From November 1997 to July 2002 49 radiofrequency ablations have been performed in 19 patients (11 male and 8 female; mean age 65 years: range 50-78 years). The disease-free period was between 5 and 32 months. Nodules had a diameter <3 cm in 4 cases while in 3 cases a single lesion was present. One patient had a single lesion after 2 courses of intravenous systemic chemotherapy which had a reduced greater lesion (from 6 to 3 cm) while a 2 cm lesion had disappeared. In the remaining 12 patients the mean number of lesions is 3 (range 1-13) with a diameter between 3 and 12 cm. The radiofrequency ablation has been performed during laparotomy and vascular exclusion through clampage of the liver hilum in 4 cases and percutaneously under ultrasound guide in the remaining 15 cases. All patients underwent follow up by computed tomography, CEA level and ultrasound every 3 months. One patient only has completed a 4 year follow up and is alive without local recurrence but with a cerebral metastasis. The other 18 patients have a 32 months follow up with a survival of 50% (9 on 18). In conclusion in our exper...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.
