Correlation between the expression of TLR4 and CHI3L1 in colon cancer tissue and the prognosis after radical surgery
To investigate the correlation between the expression of Toll-like receptor 4 (TLR4) and chitosanase 3-like protein 1 (CHI3L1) in colon cancer tissue and the prognosis of patients after radical surgery.
Methods
2
A total of 152 patients who underwent radical colon cancer surgery in our hospital from January 2017 to May 2018 were collected and divided into the good prognosis group (
n
=97) and the poor prognosis group (
n
=47) according to the 5-year survival status after surgery. Immunohistochemical staining was applied to detect the expression levels of TLR4 and CHI3L1 in colon cancer tissues and adjacent tissues; the correlation between the expression of TLR4 and CHI3L1 in colon cancer tissue and the prognosis of patients was analyzed,and the influencing factors for prognosis of colon cancer patients were analyzed.
Results
2
The positive expression rates of TLR4 and CHI3L1 in colon cancer tissues were obviously higher than those in adjacent tissues (
P
<
0.05). The expression of TLR4 in colon cancer tissue was related to the degree of tumor differentiation,clinical staging,and lymph node metastasis of colon cancer patients (
P
<
0.05),the expression of CHI3L1 was related to the tumor diameter,degree of tumor differentiation,clin
ical staging,and lymph node metastasis of colon cancer patients (
P
<
0.05). Compared with the good prognosis group,the poor prognosis group had higher proportions of patients with poorly differentiated tumor,clinical stageⅢ,lymph node metastasis,and positive expression of TLR4 and CHI3L1 (
P
<
0.05). The 5-year survival rate of patient with TLR4 positive expression was 60.38%,which was lower than that of 86.84% of patients with TLR4 negative expression (
χ
2
=9.104,
P
<
0.05); the 5-year survival rate of patients with CHI3L1 positive expression was 58.06%,which was lower than that of 84.31% of patients with CHI3L1 negative expression (
χ
2
=10.935,
P
<
0.05). The positive expression of TLR4 and CHI3L1,poorly differentiated tumor,clinical stage Ⅲ,and lymph node metastasis were the independent risk factors for the prognosis of colon cancer patients (
P
<
0.05).
Conclusion
2
TLR4 and CHI3L1 are related to the occurrence and clinicopathological features of colon cancer,and the positive expression of TLR4 and CHI3L1 in colon cancer tissues is not conducive to the prognosis of patients,so both of them are expected to become clinical treatment targets.
