The prognostic value of invariant chain (Ii) and Her-2/neu expression in curatively resected colorectal cancer.

Background: Current methods to predict outcome for patients with curatively resected colorectal cancer are not ideal. The combined use of molecular markers and clinicopathologic features may better identify patients who are at risk for recurrence. The Her-2/neu and invariant chain molecules may be important in cancer development and progression, but their usefulness as clinical predictors of outcome in colorectal cancer has not been well studied.
