Histologic-prognostic correlations in adenoid cystic carcinoma of major and minor salivary glands of the oral cavity.
Thirty-four cases of adenoid cystic carcinoma (ACC) of the major and minor salivary glands of the oral cavity, treated by wide surgical excision, were studied. The relationship between prognosis of the neoplasm and various morphologic factors were evaluated. Among the morphologic parameters previously studied, which according to various authors may be linked to the evolution of this tumor, we confirmed correlations for both histologic patterns and perineural invasion. In addition, the authors propose neoplastic growth type as a new parameter prognostically significant in ACC. In fact, none of the patients with the pushing type growth pattern died during the study period (p = 0.007). These same patients presented disease-free periods (mean 56 months, median 58 months) significantly longer than those with the infiltrating type growth pattern (mean 28 months, median 24 months).
