Loss of gastric gland mucin-specific O-glycan is associated with progression of differentiated-type adenocarcinoma of the stomach.
Bottom Line: Loss of αGlcNAc was also significantly associated with poorer patient prognosis in MUC6-positive differentiated-type adenocarcinoma.In undifferentiated-type adenocarcinoma, we observed no significant correlation between mucin phenotypic marker expression, including MUC6, and any clinicopathologic variable.These results together indicate that loss of αGlcNAc in MUC6-positive cancer cells is associated with progression and poor prognosis in differentiated, but not undifferentiated, types of gastric adenocarcinoma.

Mentions: In undifferentiated-type adenocarcinoma, no significant correlations were observed between mucin marker expression and any clinicopathologic variable analyzed (Table2). Mucin marker expression was also not associated with 5-year cancer-specific survival in patients with undifferentiated-type adenocarcinoma (Fig.3).
