Objective To investigate the relationship between quantitative detection of T lymphoma invasion and metastasis inducing factor (Tiaml) mRNA and invasion,metastasis and prognosis of patients with colorectal cancer.Methods The quantitative expression of Tiam1 mRNA in cancer tissues in colorectal cancers (n =97),in tissues of colorectal adenomatous polyposis (n =49) and normal control (n =30) were detected with real-time fluorescence quantitative-polymerase chain reaction (PCR).The relationship between the quantitative expression of Tiam1 mRNA in colorectal cancer tissues and the invasion,metastasis and the prognosis were analyzed.Results The levels of Tiam1 mRNA expression in the colorectal cancer group,were significantly higher than those in colorectal adenomatous polyposis group and normal controlgroup [(14.45±4.87)2-△△△Ct vs (3.77 ±3.15)2-△△Ct,(1.06 ±0.65)2-△△Ct,P ＜0.01].The levels of Tiam1 mRNA expression in the adenomatous polyposis with high grade intraepithelial neoplasia were signifiCantly higher than those in the adenomatous polyposis with low grade intraepithelial neoplasia [(5.26 ±2.45)2-△△Ct vs (3.78 ±2.19)2-△△Ct,P ＜0.01],which were both significantly higher than those in the adenomatous polyposis with no intraepithelial neoplasia [(2.13 ± 1.64)2-△△Ct,P ＜0.05 or P ＜ 0.01].The levels of Tiam1 mRNA expression in colorectal cancer group were positively related to the differentiated degree of tumor,depth of invasion,lymph node metastasis,tumor node metastasis (TNM) stages and the postoperative recurrence (P ＜ 0.01),and were negatively related to the postoperative survival time (P ＜0.01).Multivariate Cox regression analysis revealed that levels of Tiam1 mRNA expression in cancer tissues were independent prognostic factor for colorectal cancer (Exp =4.043).Conclusions The high Tiam1 mRNA expression levels in cancer tissues are closely related to invasion,metastasis and poor prognosis of colorectal cancer,and may be a prognostic indicator of colorectal cancer.The increase expression of Tiam1 mRNA in colorectal adenomatous polyposis may be related to colorectal tumorigenesis.

Objective:To investigate the correlation between microRNA-497 (miR-497) expression and invasion and metastasis and prognosis of colorectal cancer (CRC).Methods:The expression of miR-497 in 93 CRC patients (CRC group), 30 colorectal adenoma polyps (colorectal adenomatous polyp group) and 30 healthy patients (normal control group)were detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR); meanwhile, the content of serum carcinoembryonic antigen (CEA) was detected by chemiluminescence; After 3 years follow-up, the expression of miR-497 was measured again; the correlation between the expression of miR-497 and the clinicopathological characteristics and prognosis of CRC was analyzed.Results:The expression of miR-497 in CRC group was significantly lower than that at the end of postoperative treatment, adenomatous polyps group and normal control group ( P<0.01), and the content of CEA in CRC group was significantly higher than that at the end of postoperative treatment, adenomatous polyps group and normal control group ( P<0.01); At the end of postoperative treatment, the expression of serum miR-497 in CRC group was lower than that in normal control group ( P<0.05), and the content of serum CEA was higher than that in normal control group ( P<0.05). The diagnosis positive rate of serum miR497 expression in CRC group was significantly higher than that of serum CEA ( P<0.01), and they showed no correlation ( r=0.232, P>0.05). The pre-and post-operative serum miR-497 expression levels in the recurred and metastasis group were significantly lower than those in the no postoperative recurrence and metastasis group ( P<0.01). The preoperative expression of miR-497 was related to the differentiation degree of CRC, tumor node metastasis (TNM) stage, lymph node metastasis, distant metastasis and survival period ( P<0.01), but not with the age, sex, tumor size and location of the patients ( P>0.05). Cox multivariate analysis showed that tumor differentiation, TNM stage, preoperative miR-497 expression, lymph node metastasis and distant metastasis were all independent risk factors influencing prognosis of CRC patients ( P<0.05); The survival rate of 1, 2, 3 years in the miR-497 low expression group was lower than that in the miR-497 high expression group ( P<0.05). Conclusions:The preoperative low serum miR-497 expression levels are closely relative with invasion and metastasis and poor prognosis of CRC, and can be a prognostic indicator of CRC. The reduced postoperative serum miR-497 expression levels may be a predictor of the postoperative recurrence and metastasis of CRC.

ObjectiveTo study the correlation between preoperative serum angiopoietin-2 (Ang2) levels and lymph node metastasis in early gastric cancer(EGC).MethodsPreoperative serum Ang-2 and CEA levels in 62 patients with EGG and 30 normal controls were measured by ELISA technique respectively.The metastasis of lymph node in these cases were determined by HE staining.The relation between preoperative serum Ang-2 levels and lymph node metastasis in EGC and pathologic characterization was investigated.ResultsCompared with normal controls,preoperative serum Ang-2 levels in EGC group were significantly elevated [( 282.5 ± 110.6 ) μg/L vs ( 187.4 ± 32.7 ) μg/L,P ＜ 0.01].Preoperative serum Ang-2 levels in node-positive gastric cancer group was significantly higher than that in the node-negative gastric cancer group [(34 7.2 ± 79.5 ) μg/L vs (265.6 ± 90.2) μg/L,P ＜ 0.01],while CEA levels changed a little.Preoperative serum Ang-2 levels in the EGC group presented marked correlation with the differentiated degree of the tumor tissue,tumor size,depth of tumor invasion but it had no correlation with the histological type.Preoperative serum Ang-2 levels were an independent high-risk factor of lymph node metastasis in EGC according to multivariate logistic regression analysis.ConclusionsPreoperative serum Ang-2 levels may be a good clinical predictor for lymph node metastasis of EGC,which is useful for the treatment direction.

Objective To investigate the correlation between expression of human telomerase reverse transcriptase (hTERT) mRNA in peripheral blood and postoperative recurrence and prognosis in the patients with advanced colorectal cancer (CRC).Methods The preoperative and 1 month postoperative quantitative expression of hTERT mRNA in peripheral blood in 85 patients with advanced CRC were detected with real-time fluorescence quantitative real-time fluorescence quantitative polymerase chain reaction (RTPCR).The quantitative expression of hTERT mRNA in peripheral blood in 30 normal controls were also detected.The postoperative prognosis was followed-up,and the quantitative expression of hTERT mRNA in peripheral blood in the patients with recurred CRC and the patients without recurred CRC were detected repeatedly.The factors that affected the preoperative hTERT mRNA expression were analyzed.The relationship was investigated between the hTERT mRNA expression levels and postoperative recurrence and prognosis in the patients with advanced CRC.Results The hTERT mRNA expression levels in peripheral blood in advanced CRC group were significantly higher than those in the normal controls [(6.22 ±5.85)2-△△Ct vs (0.45 ±0.27)2-△△Ct,(P ＜0.01)],and were significantly decreased at the time point of 1 month after the operation (P ＜ 0.01).The hTERT mRNA expression levels in the postoperative recurred CRC group were significantly higher than those in the 1 month postoperation group and no recurrence CRC group [(5.07 ± 2.87)2-△△Ct vs (1.83 ± 1.08)2-△△Ct,(2.15 ± 1.49)2-△△Ct,(P ＜0.01)].Univariate analysis revealed that preoperative high hTERT mRNA expression levels in peripheral blood were related to the differentiated degree of tumor,tumor size,lymph node metastasis ratio,and liver metastasis (P ＜ 0.05 or P ＜ 0.01).Multivariate logistic regression analysis revealed that differentiated degree of the tumor,lymph node metastasis,and liver metastasis were independent risk factors for the elevation of preoperative hTERT mRNA expression in the advanced CRC.Elevated preoperative hTERT mRNA expression was positively related to the postoperative recurrence rate,and was negatively related to postoperative survival rate.Conclusions Preoperative hTERT mRNA expression levels in peripheral blood were related to the important pathologic features in patients with advanced CRC,and might be a valuable prognostic factor.Postoperatively elevated hTERT mRNA expression in peripheral blood was related to recurrence of advanced CRC.
