... progressed to carcinoma and of 30 patients with nonprogressed lesions in a period of 60 months follow-up, in order to identify if any differences existed between low-risk and high-risk dysplasias. Increased frequency of chromosomal breaks, SCEs and C-band heteromorphisms of chromosome 1 and decreased...

... of chromosome 1 in patients with cancer (48.39%) and severe dysplasias (40%) as compared to controls (29.8%) and lower grades of dysplastic lesions, i.e. mild and moderate (28.8%). The increase in the incidence of chromosome 1 heteromorphisms in cancer was found to be statistically significant (p <0.05...

...Won Ae Lee α-Methylacyl-CoA-racemase (AMACR) is an essential enzyme in the oxidation of bile acid intermediates and branched-chain fatty acids. This study aims to examine the expression pattern, as well as diagnostic and prognostic significance, of AMACR in carcinoma, dysplasia and non-neoplastic...

... analysis of TC21 was carried out in 83 ESCCs, 37 dysplasias and 29 matched histologically normal esophageal tissues and correlated with clinicopathological parameters. The cellularlocalization of TC21 was determined by confocal microscopy. Results: Expression of TC21 protein was observed in 60/83 (73...

..., OR = 3.665) and in 17/25 (68%) dysplasias (p = 0.000, OR = 4.248) compared to paired distant histologically normal esophageal tissues. Increased MEMD mRNAlevels were observed in ESCCs and dysplasias showing overexpression of MEMD/ALCAM protein. Interestingly, increased membranous MEMD/ALCAM expression...

...: For immunohistochemistry, 84 gland-forming neoplasms and 17 signet-ring cell carcinomas were examined. The gland-forming neoplasms were grouped according to the Vienna classification: group A (low-grade adenoma/dysplasia), group B (high-grade adenoma/dysplasia) and group C (intramucosal carcinoma). Results: Strong nuclear...

..., including esophageal carcinoma. We analyzed Fhit expression using an immunohistochemical method in invasive carcinoma, carcinoma in situ (CIS) and dysplasia, in paraffin sections of 75 esophageal squamous cell carcinomas (ESCs) to further elucidate the role of Fhit protein in esophageal carcinogenesis...
