Predicting tumor progression is one of the major challenges in oncology. Scientists at the University of Geneva (UNIGE) and the Ludwig Institute for Cancer Research have discovered that neutrophils, a type of immune cell, undergo reprogramming when they come into contact with the tumor ecosystem and contribute to its progression. They then produce a molecule—the chemokine CCL3—which promotes cancer growth rather than fighting it. This mechanism appears to be a major variable in tumor biology and could serve as an indicator of disease progression. These findings are published in the journal Cancer Cell.
