IL33 and breast angiosarcoma: Dong et al.24 found that the serum IL-33 level was significantly higher in BA patients (791.0 ± 22.22 pg/mL) than in non-BA (607.1 ± 20.68 pg/mL) and HC (588.5 ± 27.71 pg/mL) groups (both p < 0.001), but no significant difference was observed between the latter groups (p > 0.05).
