Positive identified proteins that were significantly increased greater than threefold with p < 0.05 (2-sided t test) and a stromal contribution of > 50% are shown. Normal, normal adjacent mucosa; tumor, tumor tissue; High, high stage tumor samples; low, low stage tumor samples; SC, stromal contribution.
