Estrogen receptor distribution in the peripheral, intermediate and central regions of breast cancers

European Journal of Cancer & Clinical Oncology

Abstract

The central, intermediate and peripheral regions of 25 breast tumors were analyzed for estrogen receptors (ER) using a combined biochemical (BC)/immunohistochemical (IHC) micromethod. To optimize the regional comparison, the percentage carcinoma per sample (PCS) was evaluated and incorporated into the quantification of the ER. Correction of the measured ER for the PCS eliminated differences in receptor levels between the central and peripheral regions but not the intermediate region. Although the corrected BC-ER level in this region was found to be about 20% higher, the IHC method did not detect such a difference. Determination of the ER status at the actual growth front of a tumor, rather than in the intermediate region where ER levels appear to be highest, may be of greater clinical relevance. Intra-regional ER heterogeneity appears, however, to be particularly pronounced in this area of a tumor.

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.

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.
