IL-6, IL-8 and TNF-α levels correlate with disease stage in breast cancer patients

The study showed that IL-6, IL-8 and TNF-α levels correlated with clinical disease stage and lymph node metastasis as well as with ER and HER2 antigen expression. Specifically, IL-6 and IL-8 seem to have significant potential as prognostic cancer biomarkers. Analyzing serum cytokine levels might help identify patients with a poor prognosis who may benefit from more aggressive disease management.
