Measurement of c-myc oncoprotein provides an independent prognostic marker for regional metastatic melanoma

Abstract

Patients with melanoma who develop nodal metastatic disease represent a group with heterogeneous clinical outcome. Nodal positivity remains the most accurate prognostic marker for regional melanoma although it fails to predict outcome in a significant number of patients. Recent studies have illustrated the prognostic potential of c-myc oncogene expression in melanoma. The aim of this study was to measure c-myc oncoprotein in a series of regional metastatic specimens from 48 patients, and evaluate its use as a marker of clinical outcome. Oncoprotein expression was detected in 46 (96%) of the tumours with a median positivity of 68% (range 0-98%). Survival analysis revealed a significant association between oncoprotein positivity and survival (Long-Rank test, chi 2 = 15.2, P < 0.001). Multivariate analysis of outcome showed c-myc oncoprotein to be an independent prognostic marker more accurate than all other clinicopathological parameters including nodal positivity (chi 2 = 8.34, P = 0.003). Estimation of c-myc oncoprotein is therefore recommended as a powerful prognostic marker for regional metastatic melanoma.

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.
