| [ Summary ] | It is important to consider two chromocolonoscopic findings using crystal violet, pit pattern and SA pattern, in detecting invasive colorectal cancers. Close correlation was found between complexities of pit pattern and grandular atypia. The more complicated the shapes of pits become, the higher the grade of atypia of the equivalent glands becomes. However, little co-relation was found between pit pattern and the invasion depth. SA pattern which is the staining pattern of the area between pits, was classified into three types, stained, fading, unstained. These patterns, correlate with not only histologic depth of cancer invasion but also histologic changes of the stromal components including mucosal layer, muscularis mucosae and desmoplasia. |
