Molecular Oncology Testing in Resource-Limited Settings

Cancer prevalence and mortality are high in developing nations, where resources for cancer control are inadequate. Nearly one-quarter of cancers in resource-limited nations are infection related, and molecular assays can capitalize on this relationship by detecting pertinent pathogen genomes and human gene variants to identify those at highest risk for progression to cancer, to classify lesions, to predict effective therapy, and to monitor tumor burden over time. Prime examples are human papillomavirus in cervical neoplasia, Helicobacter pylori and Epstein-Barr virus in gastric adenocarcinoma and lymphoma, and hepatitis B or C virus in hepatocellular cancer.

CONCLUSION: An exclusively extranodal manifestation of cHL in Waldeyer's ring is rare, whereas infiltration of extranodal tissue in the case of a primary manifestation of lymphoma in cervical nodes can occur more frequently and may often remain undiagnosed. Therefore, a specialized ENT consultation could be a reasonable complementary module in tumor staging to determine the correct tumor extent. PMID: 31712877 [PubMed - as supplied by publisher]

Authors: Sun L, Yin H, Liu M, Xu G, Zhou X, Ge P, Yang H, Mao Y Abstract Albumin is the most abundant plasma protein and albumin infusion is commonly used. Conventionally, the biologic and therapeutic effects of albumin have been thought to be due to its oncotic properties. However, albumin has a variety of biologic functions, including molecular transport, anti-oxidation, anti-inflammation, endothelial stabilization, anti-thrombotic effects, and the adjustment of capillary permeability. Despite this, the functions of albumin have not been thoroughly investigated. Recent studies have shown non-alcoholic fatty liver...

In this study, we discovered that miR-561 expression was downregulated in human NSCLC tissues and cell lines. The overexpression of miR-561 inhibited NSCLC cell proliferation and cell cycle G1-S transition and induced apoptosis. The inhibition of miR-561 facilitated cell proliferation and G1-S transition and suppressed apoptosis. MiR-561 expression was inversely correlated with P-REX2a expression in NSCLC tissues. P-REX2a was confirmed to be a direct target of miR-561 by using a luciferase reporter assay. The overexpression of miR-561 decreased P-REX2a expression, and the suppression of miR-561 increased P-REX2a expression...
