The prognostic value of CDX2 in colorectal cancer: a meta-analysis

چکیده
Caudal-type homeodomain transcription factors 2 (CDX2) acts as an intestine-specific transcription factor is essential for intestinal differentiation and development, which shows a low expression in colorectal cancer tissues. However, the prognostic role of CDX2 in colorectal cancer remains controversial. Here, a meta-analysis of eight published studies containing 2547 patients was conducted to evaluate the prognostic value of CDX2 in colorectal cancer by calculating the hazard ratio (HR) and its 95% confidence interval (CI). The summary results revealed that the low expression of CDX2 was association with poor prognosis of OS (HR=1.99, 95% CI: 1.31-3.02) and DFS (HR=1.81, 95% CI: 1.08-3.05). Subgroup analysis showed decreased CDX2 was a significant prognostic marker in Asian patients (HR=2.66, 95% CI: 1.38-5.13), but not in Caucasian (HR=1.56, 95% CI: 0.94-2.59). This meta-analysis demonstrated that CDX2 could act as a significant biomarker in the prognosis of colorectal cancer.

Homeobox protein CDX2 as a prognostic biomarker in solid malignancies: a meta-analysis
Background CDX2 is a caudal-homeobox gene and its expression is abnormal in numerous tumour cell types. Nevertheless, its prognostic value for solid tumours requires further investigation. Hence, we conducted a meta-analysis to determine the significance of CDX2 as a prognostic biomarker in solid malignancies systematically. Materials and Methods We performed a systematic literature search in...
متن کاملLoss of Cdx2 Expression in Primary Tumors and Lymph Node Metastases is Specific for Mismatch Repair-Deficiency in Colorectal Cancer
BACKGROUND Approximately 20% of all colorectal cancers are hypothesized to arise from the "serrated pathway" characterized by mutation in BRAF, high-level CpG Island Methylator Phenotype, and microsatellite instability/mismatch repair (MMR)-deficiency. MMR-deficient cancers show frequent losses of Cdx2, a homeodomain transcription factor. Here, we determine the predictive value of Cdx2 expressi...

Cdx2 is a homeobox domain-containing transcription factor that is important in the development and differentiation of the intestinal cells, and served as a potential biomarker of tumor progression in early intestinal-type gastric cancer. However, its prognostic value and significance in gastric cancer remain controversial. A meta-analysis based on published studies was performed to obtain an ac...

Background: Bax and Bcl-2 are the major members of Bcl-2 family whose play a key role in tumor progression or inhibition of intrinsic apoptotic pathway triggered by mitochondrial dysfunction. Therefore, the balance between pro- and anti-apoptotic members of this family can determine the cellular fate. Methods: In this study, the relative level of mRNA expression of Bax and Bcl-2 genes was deter...

PURPOSE The homeodomain transcription factor CDX2 is a relatively specific immunohistochemical marker for gastrointestinal carcinoma. However, no study has comprehensively examined the relationship between CDX2 expression in colon cancer and clinical, pathologic, prognostic, and molecular features, including microsatellite instability and CpG island methylator phenotype (CIMP). EXPERIMENTAL D...
