Summary
Brief summary (as posted)
Gastric carcinoma (GC) is the second leading cause of cancer death throughout the world. In previous multi-center study, we have found that the prevalence of GDNF family receptor alpha 1(GFRA1), serum response factor (SRF), and ZNF382 methylation alterations were inversely and coordinately associated with GC metastasis and the patients' overall survival throughout discovery and testing cohorts in China, Japan and Korea. The present cohort study is to investigate whether methylation of those genes can predict the metastasis and prognosis of GC.

- gene-methylation
- description
- gene-low-level of methylation: patients with early stage gastric carcinoma containing low-level of methylation change of E-cadherin,GFRA1,p16,SRF and ZNF382 CpG island. gene-middle-level of methylation: patients with early stage gastric carcinoma containing middle-level of methylation change of E-cadherin,GFRA1,p16,SRF and ZNF382 CpG island. gene-high-level of methylation: patients with early stage gastric carcinoma containing high-level of methylation change of E-cadherin,GFRA1,p16,SRF and ZNF382 CpG island. gene-without of methylation: patients with early stage gastric carcinoma NOT containing methylated E-cadherin,GFRA1,p16,SRF or ZNF382 CpG island.
Primary outcomes (1)
- measure
- Metastasis and/ or recurrence of gastric carcinoma
- timeFrame
- 3 years
- description
- The hazard ratio, positive prediction value, and negative prediction value of metastasis/recurrence of gastric carcinomas are calculated according to the metastasis/recurrence frequences among patients with the different methylation status of each target gene CpG islands. These patients are classified into four groups for each gene: A) cases without methylation change; B) cases with the low-level of methylation change (33.3% of cases with methylation change); C) cases with the middle-level of methylation change (33.3% of cases with methylation change); D) cases with the high-level of methylation change (33.3% of cases with methylation change). Combination analysis will be carried out using Support Vector Classification model.
