When comparing between g-BA and p-BA subgroups, ELISA showed significantly elevated IL-33 levels in the serum of p-BA patients, indicating the predictive property of IL-33 for disease prognosis (289.7 ± 65.0 vs. 80.8 ± 35.0 pg/ml, p = 0.0105, Figure 3A). The gene discussed is IL33; the disease is breast angiosarcoma.
