Real-World Treatment Patterns and Outcomes in Patients Receiving Second-Line Therapy for Advanced/Metastatic Esophageal Squamous Cell Carcinoma.

Advances in Therapy

Abstract

Currently available second-line (2L) therapies for advanced/metastatic esophageal squamous cell carcinoma (adv/met ESCC) include the taxanes paclitaxel and docetaxel. In clinical trials, such therapies have provided only modest improvements in survival. Few studies have assessed outcomes in routine clinical practice in the USA. We compared real-world clinical outcomes in the US for patients receiving taxane or non-taxane 2L therapy for adv/met ESCC. The Flatiron Health database was used to identify patients diagnosed with adv/met ESCC (1 January 2011-31 January 2019) who received 2L therapy; index date was date of adv/met diagnosis. Baseline variables and treatment regimens received were identified. Overall survival (OS; 2L start until death or last recorded medical activity) and duration of therapy (DoT; start of 2L therapy until last administration date of 2L therapy) in patients receiving taxane vs. non-taxane-based therapies in the 2L setting were estimated by Kaplan-Meier method. There were no clear differences in baseline characteristics between patients who received 2L taxane therapy (n = 37) and 2L non-taxane therapy (n = 49). Median (95% CI) 2L OS was significantly longer with 2L taxanes (7.3 [5.9-11.5] months) vs. 2L ...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.
