Overexpression of homeobox B9 (HOXB9) is associated with poor survival rate of colon cancer patients and lymph node metastasis. (A) Kaplan-Meier curves for overall survival are shown based on the expression of HOXB9 (P=0.013); (B) Representative micrographs of HOXB9 expression in colon cancer metastatic lymph nodes (m-LN) and non-metastatic lymph nodes (n-LN); (C) The expression levels of HOXB9 were significantly higher in m-LNs than in n-LNs; (D) The ratio of HOXB9 overexpression was high in colon cancer tissue-corresponding metastatic lymph nodes, regardless of the HOXB9 status in the corresponding tumors.
