From: Prognostic value of HLA class I expression in patients with colorectal cancer
Five- year disease- free survival curves of patients with adjuvant chemotherapy. The 5-year DFS rates of patients with HLA class I positive expression (black circle) and with dull and negative expression (white circle) were compared. The 5-year DFS in patients with HLA dull and negative expression was decreased more than that of those with HLA positive expression, although there was no significant difference (P = 0.10).
