Clinical Significance of NADPH Oxidase 5 in Human Colon Cancer.

Abstract

BACKGROUND/AIM:

Recent studies have reported the involvement of NADPH oxidases (NOXs) in tumor progression. However, the role of NOX5 in colon cancer is unclear. We examined the clinical significance of NOX5 expression in colon cancer.

PATIENTS AND METHODS:

NOX5 expression was evaluated by immunohistochemistry in 119 patients with stage II or III colon cancer, and the relationship between NOX5 expression and clinicopathological data was analyzed.

RESULTS:

Of all tissues, 39.5% were negative and 60.5% were positive for NOX5 expression. Positive expression was significantly associated with undifferentiated histology (p=0.037) and lymph node metastasis (p=0.023). The 5-year progression-free survival rate of NOX5-positive patients was significantly worse than that of NOX5-negative patients (p=0.046). The rates of local recurrence observed in NOX5-positive patients were higher than that in NOX5-negative patients.

CONCLUSION:

NOX5 expression may be related to poor prognostic factors and could be useful as a prognostic biomarker.
