Interleukin (IL)-32 is a described intracellular pluripotent pro-inflammatory mediator, characterized by the signaling of NF-κB and STAT3.
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.
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).
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.
白细胞介素（IL）-32是一种已被描述的细胞内多能促炎介质，其特征在于核因子κB（NF-κB）和信号转导与转录激活因子3（STAT3）的信号传导。
我们的研究调查了IL-32表达在结直肠癌（CRC）转移中是否具有临床意义。共纳入70例CRC患者，其中47例为单一CRC器官转移病灶，其余为原发性CRC病灶（T4NxM0）。采用免疫组织化学法检测IL-32表达，并分析IL-32表达与CRC转移之间的相关性。
CRC器官转移组中IL-32的阳性率高于原发性CRC组（P<0.05）。有淋巴结转移的原发性CRC中IL-32的阳性率高于无淋巴结转移的原发性CRC中IL-32的阳性率（P<0.05）。
IL-32表达水平可影响CRC的N分级。因此，IL-32表达可能促进CRC的器官转移和淋巴结转移。
