Clinical data were obtained from the medical records, the microscopic slides were reviewed, the tumors were graded, and immunohistochemical analysis for p53, PCNA, cerbB\u20102, and CEA were carried out.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The tumors were more frequent in patients between 40 and 60 years of age (40.7%), without gender predilection. Hard palate was the most common site with 13 cases (48%). T2 was the more frequent stage (48%) and 2 patients (7.4%) were staged as N +. Most tumors (48%) were classified as low grade of malignancy. The expression of PCNA was associated to high\u2010grade tumors (<jats:italic>P<\/jats:italic> =. 00610) and c\u2010erbB\u20102 to low grade tumors (<jats:italic>P<\/jats:italic> =. 03958). No recurrence was noted in most of the cases (22 cases, 81.5%). Three cases (11.1%), however, showed local recurrence and 2 patients (7.4%) died because of the disease. The analysis of the overall survival rate showed that male patients (<jats:italic>P<\/jats:italic> =. 04249), stage N (<jats:italic>P<\/jats:italic> =. 05948), high grade of malignancy (<jats:italic>P<\/jats:italic> =. 0009), strong expression of PCNA (<jats:italic>P<\/jats:italic> =. 09128), and weak expression of c\u2010erbB\u20102 (<jats:italic>P<\/jats:italic> =. 03334) had the lowest survival rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Our results showed that patients with intraoral mucoepidermoid carcinoma had a reduced survival expectation if they were of the male gender, with regional metastasis, high grade of malignancy, strong expression of PCNA and weak expression of c\u2010erbB\u20102.<\/jats:p><\/jats:sec>","DOI":"10.1016\/j.otohns.2005.12.012","type":"journal-article","created":{"date-parts":[[2006,3,28]],"date-time":"2006-03-28T07:10:13Z","timestamp":1143529813000},"page":"622-626","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Clinicopathologic and Immunohistochemical Study of Intraoral Mucoepidermoid Carcinoma"],"prefix":"10.1002","volume":"134","author":[{"given":"M\u00e1rcio Ajudarte","family":"Lopes","sequence":"first","affiliation":[{"name":"Department of Oral Semiology and Pathology School of Dentistry of Piracicaba\/UNICAMP, Piracicaba S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danyel Elias","family":"da Cruz Perez","sequence":"additional","affiliation":[{"name":"Department of Oral Semiology and Pathology School of Dentistry of Piracicaba\/UNICAMP, Piracicaba S\u00e3o Paulo Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F\u00e1bio","family":"de Abreu Alves","sequence":"additional","affiliation":[{"name":"Department of Stomatology Cancer Hospital A.C.
