Background: Interleukin (IL)-32 is a described intracellular pluripotent pro-inflammatory mediator, characterized by the signaling of NF-kappa B and STAT3. Methods: Our study investigated whether IL-32 expression has clinical significance in the metastases of colorectal cancer (CRC). A total of 70 CRC patients were enrolled, 47 cases of which were single CRC organic metastasis lesions while the rest of which were primary CRC lesions (T4NxM0). IL-32 expression was detected by immunohistochemistry, and the correlation between IL-32 expression and CRC metastases was analyzed. Results: The positive rates of IL-32 in the CRC organic metastasis group were more severe than those in the primary CRC group (P < 0.05). The positive rate of IL-32 in primary CRC with lymph node metastasis was more severe than that of IL-32 in primary CRC without lymph node metastasis (P < 0.05). Conclusions: The level of IL 32 expression could influence the N grade of CRC. Thus, IL 32 expression may stimulate the organic metastasis and the lymph node metastasis of CRC.
