Aberrant Methylation of HLTF , SOCS-1 , and CDH13 Genes Is Shown in Colorectal Cancers Without Lymph Node Metastasis

Abstract
In this study, we examined the combined methylation status of HLTF, SOCS-1, and CDH13 in 61 resected primary colorectal cancers using methylation-specific polymerase chain reaction and correlated the number of methylated genes with the clinicopathologic features of affected patients. We found a significant difference in lymph node metastasis (P = 0.020) when we compared the number of methylated genes in colorectal cancers with lymph node metastasis to those without it. Colorectal cancers without lymph node metastasis frequently exhibited the aberrant methylation of HLTF , SOCS-1 , and CDH13 genes.
