Salivary gland carcinomas: prognostic significance of simple mucin-type carbohydrate antigens.
    Oral oncology, 1998, Volume: 34, Issue:1

    The prognosis of salivary gland carcinomas is difficult to assess. Simple mucin-type carbohydrates (T and sialosyl-T antigens, Tn and sialosyl-Tn antigens) have been shown to be of value in predicting prognosis for carcinomas in other locations. We studied the prognostic significance of the expression of these structures in a retrospective study of 133 patients with salivary gland carcinomas, using immunohistochemistry and a panel of well-defined monoclonal antibodies (MAbs) on formalin-fixed paraffin-embedded tissues. Sialosyl-Tn, T and sialosyl-T antigens were not correlated with prognosis. Univariate analyses showed no overall difference in survival or locoregional control between patients with Tn-positive and patients with Tn-negative tumours, but indicated that expression of the Tn antigen was associated with early locoregional recurrences and deaths. Tn was, however, not an independent prognostic factor by multivariate regression analysis.

Simple mucin-type carbohydrate antigens (T, Tn and sialosyl-Tn) in mucoepidermoid carcinoma of the salivary glands.
    Histopathology, 1994, Volume: 25, Issue:6

    Thirty-two cases of mucoepidermoid carcinoma of the salivary glands were studied in order to characterize the expression of simple mucin-type carbohydrate antigens T, Tn and sialosyl-Tn and to evaluate its implication for tumour histogenesis. Monoclonal antibodies of known specificity were used on formalin-fixed, paraffin-embedded tissue, and the expression of these antigens was studied in each of the three cell types (mucous, intermediate and squamous) as well as in the secretory content of neoplastic lumina. Aberrant glycosylation of simple-mucin type antigens was found in all cell types, as compared with that of normal excretory duct cells of the salivary glands. The more 'primitive' antigens Tn and sialosyl-Tn were present in a high percentage of epidermoid and intermediate cells. Mucous cells and the intraluminal secretory content also expressed Tn in 57.7% of the cases. This contrasts with the absence of secretion of these simple mucin type carbohydrates by normal salivary gland cells. Mucin-producing cells did not express T antigen but only sialosyl-T, in contrast to 57.1% and 56.3% respectively of the epidermoid and intermediate cell types. T and sialosyl-T were also found in the secretory products of the neoplastic lumina in 11.5% and 53.6% of the cases, respectively. The distinctive glycosylation pattern between mucin-producing cells on the one hand and intermediate and squamous cells on the other does not contradict the common origin of the three cell types from the reserve cell of the salivary excretory duct, but favours the proposition that intermediate cells constitute a step in the differentiation pathway of epidermoid, but not of mucin-producing, cells.
