Abstract | AIMS: METHODS: Seventy-eight cases of head and neck squamous cell carcinoma were immunohistochemically stained for desmoglein 1, desmoglein 2, desmoglein 3, p53, bcl-2, vimentin, cyclin D1, p16, p21, p27, E-cadherin, and E2F-1 in paraffin-embedded tissue blocks in a microarray. RESULTS: The disease-specific survival was 56% at 5 years and 49% at 10 years. Expression of the desmoglein isotypes correlated positively with each other except for desmoglein 2 and desmoglein 3, which did not show a significant correlation. Desmoglein 1 and E-cadherin expression also correlated. On univariate analysis, only expression of desmoglein 1 correlated with patient outcome; lack of expression of desmoglein 1 was associated with a significantly worse disease-specific survival (p = 0.035). Hierarchical clustering analysis identified a subgroup of three patients with an immunophenotype distinct from the other tumours, characterised by co-expression of p16, p27, E2F-1 and bcl-2. Further statistical analysis of the prognostic significance of this small subgroup was not possible, but these three patients are alive and well. CONCLUSIONS:
