Abstract

In prior studies of high-dose interleukin-2 (IL-2) therapy in the treatment of metastatic renal cell carcinoma, the majority of patients were asymptomatic (65% of patients had Eastern Cooperative Oncology Group [ECOG] scores of 0 [no cancer-related symptoms]). These studies demonstrated that an ECOG score of 0 predicted an objective antitumor response to IL-2 (P = 0.03). The current study determined the response frequency to high-dose IL-2 therapy in a primarily symptomatic patient population (ECOG = 1 [presence of cancer-related symptoms] for 57.3% of patients). The IL-2 therapy was administered in a non-intensive care unit (non-ICU). In this single-institution study of high-dose IL-2 therapy, 124 patients were consecutively enrolled and treated with the drug. Antitumor responses and safety were assessed by radiographic methods and the occurrence of grade 3 and 4 adverse events, respectively. The frequency of objective responses was 14.5% (18 of 124 patients). Seven patients (5.6%) and 11 patients (8.9%) experienced complete responses (CRs) and partial responses (PRs), respectively. Two of 7 patients (28.6%) with CR and 7 of 11 patients (63.6%) with PR had ECOG scores of 1. The median response duration is 18 months for all res...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.
