Inflammatory breast cancer (IBC) remains a very aggressive cancer and women with the disease only live for a limited amount of time

A lack of dedicated IBC trials is preventing researchers and physicians from determining novel pathways to target

New discoveries about the biology of IBC has led researchers and physicians to understand pathways that are activated in the disease

Studies have found that the PI3/AKT/mTOR pathway is activated in cell lines with IBC and xenograft models

Tumor-associated macrophages cause activation of cytokines that leads to upregulation of the JAK-STAT pathway. Upregulation of this pathway leads to cell proliferation and survival

Results of animal trials have shown overall survival benefit when both the PI3/AKT/mTOR pathway and the JAK-STAT pathway were inhibited

Molecular Targets in Inflammatory Breast Cancer

Komal L. Jhaveri, MD, Assistant Professor, Department of Medicine, NYU Langone Medical Center, discusses the background and results of a study looking at crucial molecular drivers and potential therapeutic targets of inflammatory breast cancer (IBC).

The goal of this analysis was to satisfy an unmet need and understand what molecular pathways are relevant in IBC. The laboratory at the NYU Langone Medical Center has done important work with the PI3K/AKT/mTOR pathway and is aware of its relevancy in many disease types, including breast cancer.

IBCs express a lot of tumor-activated macrophages, Jhaveri says, which leads to the activation of certain signaling molecules, such as cytokines, which leads to the activation of the JAK/STAT signaling pathway.

This research team set out to understand and flesh out what was already known about the PI3K/AKT and JAK/STAT pathways as well as determine what pathways are important and activated in IBC.

The study found that in IBC, Jhaveri says, the PI3K/AKT/mTOR pathway was activated. Additionally, of the patients with an mTOR pathway activation, a very high proportion also had JAK/STAT pathway activation as well as the IL-6 and CD163 activations.
