Early gastric carcinoma with focal advanced cancer: a particular subtype of gastric carcinoma

Human Pathology

Abstract

Early gastric cancer (EGC) is defined as a carcinoma limited to the mucosa or mucosa and submucosa, irrespective of whether metastasis to lymph nodes has occurred. EGC presents a much more favorable prognosis than advanced gastric carcinoma (AGC), with a 5-year survival rate between 88% and 96% for EGC versus 45% to 50% for AGC. Moreover, some gastric cancers appear as a more or less extended EGC with focal AGC (fAGC). The purpose of this study was to analyze prognostic factors in this intermediate group of tumors. From 1981 to 1992, among the 615 gastrectomy specimens with carcinoma examined at the Institute of Pathology of the University of Lausanne, only 19 tumors corresponded to the criteria of EGC with fAGC. Clinicopathologic features were studied, and a cytophotometric DNA analysis was performed. Our results show a 5-year survival rate for EGC with fAGC of 61% (11 of 18 patients alive), intermediate between that of EGC and AGC. No significant correlations were found between the most known predictive factors and prognosis. Most tumors analyzed (16 of 19) showed a diploid DNA content in the superficial as well as in the invasive areas. Contrary to the findings in the literature, which show a high-ploidy DNA pattern in most ...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.
