Prognostic value of silver-stained nucleolar organizer regions in colorectal carcinoma

Figure 1 Moderately differentiated tubular adenomas (survived case) 10 × 20, 10 × 100).

Figure 2 Moderately differentiated tubular adenomas (died case). The AgNOR numbers, abnormal dots, large and small dots, and scattered and mixed types are significantly increased compared with survived cases (10 × 40, 10 × 100). AgNOR: Silver-stained nucleolar organizing regions.

Figure 3 Moderately differentiated tubular adenomas (primary cancer of colon): 10 × 20, 10 × 100).

Figure 4 Moderately differentiated tubular adenomas (lymphonodic metastasis). Compared with the primary cancer, the AgNOR number, large and small dots, and scattered type are increased significantly (10 × 10, 10 × 100); AgNOR: Silver-stained nucleolar organizing regions.
