Altogether, aberrant p16 methylation in plasma and elevated serum CEA level were associated with advanced tumor stage (p=0.033), tumor size (p=0.022) and extensive nodal metastasis (p=0.003).
An increase in the methylation level of mSEPT9 detected in the post-operative samples was associated with a higher mortality rate (15.2% vs 1.8%; P = 0.024) and the presence of metastasis (27.3% vs 7.0%; P = 0.013). mSEPT9 was more sensitive than CEA for diagnosing CRC, and combined mSEPT9 and CEA was more accurate.
Analysis of tumor markers of 164 MBC found that there were statistical differences in the positive rates of CEA and CA15-3 between bone metastases and other metastases (χ<sup>2</sup>=6.00, P=0.014; χ<sup>2</sup>=7.32, P=0.007, respectively).
Beclin 1 protein expression was negatively related to liver and distant metastasis (p < 0.05), but not correlated with age, sex, depth of invasion, lymphatic or venous invasion, lymph node metastasis, tumor-node-metastasis (TNM) staging, differentiation or serum carcinoembryonic antigen (CEA) concentration (p > 0.05).
Besides, we analyzed the prognostic factors for mRC and found carcinoembryonic antigen (CEA) level, metastasis (M) stage, Tumor (T) stage, tumor size, differentiate grade, age and marital status should be taken into consideration when estimating the prognosis.
By multivariate analysis, only female gender (p = 0.03), high serum carcinoembryonic antigen (CEA) level (≧5 ng/ml) (p = 0.04), and MLH1 overexpression (p = 0.003) were associated with the metastasis group.
Collectively these results suggest that the basal and interferon-stimulated expression of BGP transcripts may be regulated in a manner similar to CEA and that a potential role in the process of metastasis may be inferred.
During 3 years of follow-up, 2 patients whose peripheral blood had carcinoembryonic antigen and CD44 variant mRNA also had distant metastases (lung or spleen).
Endometrial carcinomas and their metastases were generally positive for ER (86%), PR (93%) and VIM (100%) but rarely positive for CEA (14%) and HPV (0%).
For CC, the MF group noted fewer deaths (48% versus 76%, P < 0.001), recurrences (4% versus 19%, P = 0.002), metastases (23% versus 46%, P = 0.001), better 5-year survival rates (57% versus 37%, P = 0.004), overall survival years (5.7 versus 4.1, P = 0.007) and greater carcinoembryonic antigen decrease (72% versus 47%, P = 0.015).
Further analysis showed that RP11-296E3.2 sensitivity and specificity in diagnosis of CRC metastasis is better than CEA in plasma (0.690 and 0.621, and 0.621 and 0.500, respectively), and the OS of metastatic CRC patients with higher LEF1-AS1 expression levels in tissues was short (log-rank p<0.05).
Furthermore, by immunohistochemical analysis in 348 cases of CRC specimens, we demonstrated that the WWP1 protein expression is up-regulated in 58.91% (205/348) samples and detected increasing WWP1 expression is closely correlated with enhanced tumor size (<i>P</i>=0.022), CEA level (<i>P</i>=0.021), T classification (<i>P</i>=0.010), distant metastasis (<i>P</i>=0.021) and TNM stage (<i>P</i>=0.005).
Furthermore, deguelin-treated tumors showed decreased the tumor metastasis related genes such as CD44, MMP2 and MMP9 at protein and mRNA levels and the content of CEA, SCC, NSE, CYFAR21-1.
Furthermore, lower plasma mtDNA content was associated with tumor size, lymph node metastases, distant metastases and serum carcinoembryonic antigen levels (P<0.05), but was not associated with pathological type, age, sex or main driver gene mutation status (P>0.05).
Furthermore, preoperative serum CEA level in Metastasis V-positive patients was significantly higher than in Metastasis V-negative patients (4.27 ng/mL <i>vs</i> 3.00 ng/mL).
Here, we report that TRIP13, which is overexpressed in CRC, is correlated with the CEA (carcino-embryonic antigen), CA19-9 (carbohydrate antigen 19-9) and pTNM (pathologic primary tumor, lymph nodes, distant metastasis) classification.
