From: High expression of HLA-E in colorectal carcinoma is associated with a favorable prognosis
Kaplan-Meier survival curves of patients with colorectal carcinoma. Five-year disease-free (A) and overall (B) survival rates of 149 stage II-III colorectal cancer patients according to the MEM-E/02 (HLA-E) absolute immunohistochemical score (MEM-E/02hi= 3; MEM-E/02lo/int: 0, 1 and 2). Five-year disease-free (C) and overall (D) survival of stage II-III colon carcinoma patients according to the HCA2 (HLA-A) relative immunohistochemical score (0, -1, +1 vs +2, +3, -2, -3). Patients (n = 94) with an HCA2 reactivity mimicking that seen in the normal paired mucosa (relative scores 0, -1 and +1) were sorted into MEM-E/02hi (absolute reactivity score = 3) and MEM-E/02lo/int (0, 1, and 2). The percent survival, shown in ordinate, is analytically displayed for the different groups at the end of the observation period, along with the statistical significance (p) of the observations.
