Table 2.
The percentage of IL-33-positive tissue in breast tumors, tumor-adjacent tissues, and normal tissues from breast cancer patients.
| Samples | IL-33 (%) |
|||
|---|---|---|---|---|
| N | Mean | SD | P valuea | |
| Breast carcinoma tissue | 29 | 72.6 | 34.5 | <0.0001 |
| Adjacent tissues to tumors | 29 | 64.1 | 34.7 | 0.0002 |
| Normal breast tissues from BC patients | 25b | 26.8 | 33.0 | |
BC, breast cancer.
aStatistically significantly different was found between cancer tissues vs. normal breast tissues, and between adjacent tissues vs. normal breast tissues from BC patients, using unpaired Student’s t-test. No statistical significance was found between cancer tissues and adjacent tissues.
bIn four cases, no normal breast tissues were available.
