Abstract
AIM: To analyze the clinical significance of 5-lipoxygenase (5-LOX) expression in colon cancer.
METHODS: The expression of 5-LOX in 60 colon cancer specimens and 30 normal colon specimens was examined by immunohistochemistry.
RESULTS: The positive rates of 5-LOX expression in colon cancer and normal colon tissue were 76.7% and 40.0%, respectively, with a significant difference between the two groups (P < 0.05). 5-LOX protein was moderately or strongly expressed in colon cancer, but weakly or not at all expressed in normal colon tissue. The positive rate of 5-LOX expression in stage I-II and III-IV colon cancer was 45.0% and 80.0% (P < 0.05), respectively, and that in the patients with or without lymph node metastasis were 90.0% and 60.0% (P < 0.05), respectively.. The expression rate of 5-LOX in tumor infiltrating the whole dermis and serosa was higher than that in tumor infiltrating the mucous membrane, muscular layer (87.9% vs 55.6%, P< 0.05).
CONCLUSION: Aberrant expression of 5-LOX may play a role in the development and progression of colon cancer.
