- Registration Number
- JPRN-UMIN000010926
- Lead Sponsor
- ational Cancer Center East
- Brief Summary
The size of the BCH lesions was significantly smaller (P < 0.001), and their intervascular transparency was more clearly observed (P < 0.001). IPCL (intra-epithelial papillary capillary loop) shapes were less variable and monotonous (P < 0.001), and the distribution of the IPCLs was more regular with an interval comparable to that of SCC (P < 0.001), though no significant differences in the sharpness of the lesion border or the morphological changes in the IPCLs were seen between the BCH and SCC lesions.
