Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

PI3K(phosphatidylinositol 3-kinase)/AKT pathway is an important oncogenic signaling pathway. However, clinical information about the significance of p-AKT expression in malignant lymphoma is not fully understood yet. In this study, we investigated the overexpression of p-AKT and its prognostic implication in malignant lymphoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Recently, among diverse oncogenic signaling pathways, a number of studies have focused on the significance of oncogenic PI3K/AKT (phophatidylinositol 3-kinase/serine-threonine kinase, also known as protein kinase B \[PKB\]) pathway. PI3K(phosphatidylinositol 3-kinase)/AKT pathway phosphorylates and activates AKT as phosphorylated AKT (p-AKT) and plays a critical role promoting malignant phenotype and has prognostic significance in various solid cancers.

However, a systematic approach on the impact of p-AKT overexpression on clinical outcomes has not been performed in malignant lymphoma.
