Abstract [en]

The polymorphism at codon 201 of the "deleted in colorectal carcinoma" (DCC) gene has been liked to susceptibility to colorectal cancer. However, its clinicopathological significance has not been reported. We examined the codon 201 polymorphism and loss of heterozygosity (LOH) by PCR-restriction fragment length polymorphism (PCR-RFLP) in 59 colorectal cancers, 48 samples from transitional mucosa and 67 samples from normal mucosa. The frequencies of the polymorphism did not significantly differ from normal to transitional mucosa and to tumor, but LOH was increased from transitional mucosa to tumor. Almost all of the LOH cases showed the polymorphism. The polymorphism was increased from well/moderately to poorly differentiated and to mucinous carcinoma (P = 0.03). The polymorphism was more frequently seen in advanced stages than in earlier stages (P = 0.02), and further predicted worse survival (P = 0.04). The data suggest that the codon 201 polymorphism of the DCC gene was a target of LOH, and predicted prognosis in colorectal cancer patients. ⌐ 2003 International Society for Preventive Oncology.
