Table 5.
Average MVC (no. of microvessels/mm2) | |||
---|---|---|---|
Upper (≤150)a | Middle (>150 to ≤300)a | Lower (>300 to ≤450)a | |
Normal mucosa (NM) | 157.3 ± 51.5 | 82.7 ± 32.0 | 84.0 ± 51.0 |
Hyperplasia (HP) | 97.3 ± 62.3 | 118.7 ± 52.8 | 70.7 ± 31.6 |
Tubular adenoma (TA) | 89.3 ± 40.5 | 174.7 ± 43.6 | 84.0 ± 56.6 |
Microvessel count was defined as the sum of the number of all individual microvessels in a field. MVC differed significantly between NM and HP (P = 0.04) and between HP and TA (P = 0.012) in the upper layer
aMicrovessels were divided into the following three groups according to mucosal surface–vessel distance: upper layer (≤150 μm), upper and middle layer (>0 to ≤300 μm), and all layers (>0 to ≤450 μm)
