Is overexpression of eukaryotic initiation factor 4E correlated with increased risk for systemic dissemination in node-positive breast cancer patients?
High eIF4E is correlated with an increased risk for systemic metastasis in node-positive breast cancer patients. High eIF4E overexpression was associated with a higher incidence of metastasis to multiple sites. Therefore, high eIF4E overexpression appears to be a marker for molecular events that increases risk for systemic dissemination.
The TAC haplotype includes the moderately inactivating variant rs1801725 and absence of the gain-of-function rs1042636 polymorphism. Thus, its association with metastatic disease and poor outcome would add to our previous data and further support that inactivation of the CaSR gene is a mechanism associated with neuroblastoma malignant behavior.
