Objective To study the correlation between lymphangiogenesis and ectopic expression of β-catenin in colorectal cancer (CRC). Methods Microlymphatic density (MLD) in 96 cancer tissues of CRC patients and their normal large intestine samples was detected with the specific lymphatic marker
podoplanin
and comparatively studied using CD31 as a marker of blood vessels. Expression of β-catenin in CRC was detected with the immunohistochemical S-P method. Results β-catenin was positively expressed in cell membrane of normal large intestine mucosa and ectopically expressed in cell nuclei and/or cytoplasm in tumor cells
with an ectopic expression rate of 67.71%. The MLD was significantly higher in CRC than in normal large intestine mucosa(t=3.624
P0.01)and in CRC with ectopic β-catenin expression than in CRC without ectopic β-catenin expression(t=2.843
P0.01). Conclusion Ectopic expression of β-catenin in CRC may be the major reason of lymphangiogenesis.
