老年结直肠癌血清可溶性细胞间黏附分子-1及炎性因子表达的临床意义

目的：探讨血清可溶性细胞间黏附分子‐1（sICAM‐1）及炎性因子C反应蛋白（CRP）、白细胞介素‐17（IL‐17）]在老年结直肠癌（CRC）患者中表达的临床意义。方法采用酶联免疫吸附测定（ELISA）对76例老年CRC患者（老年CRC组）及32例中青年CRC患者（中青年CRC组）手术前后外周血中sICAM‐1、CRP和IL‐17的表达水平进行检测，分析其与临床病理参数间的意义，并与60例健康体检者（对照组）比较。结果不同年龄CRC患者术前和术后血清sICAM‐1和IL‐17水平均高于对照组（P＜0．05），术后二者水平较术前均明显降低（P＜0．05）。中青年CRC组术后及老年CRC组术前、术后CRP水平均与对照组，差异无统计学意义（P＞0．05）。中青年CRC组术前CRP水平高于对照组（P＜0．05）。中青年CRC组术前和术后血清sICAM‐1和IL‐17水平与老年CRC组比较，差异有统计学意义（P＜0．05），而CRP水平两组，差异无统计学意义（P＞0．05）。老年CRC患者中sICAM‐1水平在分化程度、浸润深度、伴有淋巴结转移及TNM分期等方面组间差异有统计学意义（P＜0．05）；IL‐17水平在分化程度、浸润深度、伴有淋巴结转移、肿瘤大小及TNM分期等方面组间差异有统计学意义（P＜0．05）；CRP水平在浸润深度、伴有淋巴结转移及TNM 分期等方面组间差异有统计学意义（P＜0．05）。结论血清sICAM‐1、CRP和IL‐17水平在一定程度上反映了老年C RC的侵袭转移过程，在预测老年C RC患者发展及预后方面具有重要意义。

Expression of soluble intercellular adhesion molecule-1 and inflammatory factor in elderly patients with colorectal carcinoma

Objective To investigate the clinical significance of soluble intercellular adhesion molecule‐1 and inflammatory factors (CRP ,IL‐17) in elderly patients with colorectal carcinoma .Methods The expression of sICAM‐1 ,CRP and IL‐17 in 76 ca‐ses of elderly patients and 32 cases of youg patients with colorectal cancer were detected by enzyme linked immunosorbent assay be‐fore and after surgery ,and to analyze its clinical significance correlated with pathological parameters .Meanwhile ,60 cases of healthy were controls .Results The serum levels of IL‐17 and sICAM‐1 were higher in patients with different ages of colorectal cancer than those of the normal control group (P<0 .05) ,and the concentrations of the two group after operation were significantly lower than those of the normal control group (P<0 .05) .The CRP levels of the young group and old group were similar to that of the normal control group (P>0 .05) .The level of CRP before operation in the young group was higher than that in the normal control group (P<0 .05) .The levels of serum IL‐17 and sICAM‐1 were significantly different between the young and the old group(P<0 .05) , while the CRP level was similar in the two groups (P>0 .05) .The serum levels of sICAM‐1 and IL‐17 in colorectal cancer patients were associated with the degree of differentiation ,depth of invasion ,lymph node metastasis and TNM staging (P<0 .05) .The level of CRP was significantly correlated with the depth of invasion ,lymph node metastasis and TNM staging (P<0 .05) .Conclusion The serum levels of sICAM‐1 ,CRP and IL‐17 reflect the invasion and metastasis of colorectal cancer in a certain extent ,which play important roles in predicting the development and prognosis of colorectal cancer .
