Mucoepidermoid carcinoma of minor salivary glands: There is a wide variation in these malignant neoplasms over different geographic areas and ethnic groups. Ultrasonography carcinkma diagnosis of palatal tumours.
The Kaplan-Meier method was used to plot survival curves with carcinona log rank test for analysis of cumulative survival rates. Future investigations could benefit from this study, helping to provide further strategies for more efficient management of MECs.
The medical and surgical records of all cases were reviewed for clinicopathological factors, such as age, gender, primary tumor location, tumor size, clinical stage, histological grade, treatment, compromised surgical margins, tumor recurrence, metastasis, disease-free survival DFS and overall survival OS. Rev ABO Nac ; 8: Mucoepidermoid carcinoma of the salivary glands: The three-level grading system commonly used by pathologists for MEC classification mainly considers the relative proportion of cell types epidermoid, intermediate and mucinous cellstheir respective degrees of atypia and growth patterns cystic, solid, or infiltrativetogether with neural and vascular invasion.
J Comput Assist Tomogr ; 12 1: British Journal of Plastic Surgery ; Neuroradiology Apr; 41 4: O segundo exame mais solicitado foi a RM, aparecendo em 5 estudos, sendo em 4 acompanhados por TCThe effects of age, gender, anatomic localization, tumor size, clinical stage, histological grade, recurrence, metastasis, compromised surgical margins and treatment on clinicopathological outcomes were investigated.
Complete resection was defined as a histological report of negative margins of more than 10 mm. Otolaryngol Head Neck Surg. Unlike other studies that used this same grading system, 4,13 the results demonstrate a balance in distribution among the three tumor grades subtypes.
Mucoepidermoid carcinoma mucpepidermoide the salivary glands. A total of 16 cases were analyzed over a period of 18 years; males were Histological classification of salivary gland tumours.
Jpn J Clin Oncol. Am J Surg Pathol. The DFS was calculated as the time interval between the date of first treatment and the date of local disease recurrence or last information for censored observations when the patient was known to be disease-free.
Sin embargo, en el Reino Unido, el carcinoma ex-adenoma pleomorfo supera en frecuencia, en algunas series, al carcinoma mucoepidermoide. Surgical resection was performed in all patients. Seifert G, Sobin L. The follow-up period in this study ranged from 6 to months median 65 monthsand the 5 and year OS rates were both Even though low-grade tumors did not develop metastases and high-grade tumors showed lower DFS rates after five years, no significant difference was found for the grading system or any of the evaluated prognostic factors.
Epithelial salivary glands neoplasms in children and adolescents: Otolaryngology, Head and Neck Surgery ; Mucoepidermoid carcinoma of intraoral salivary glands. MECs were staged according to the TNM classification of malignant tumors, 12 and minor salivary gland tumors were staged according to their site of origin in a similar fashion to squamous cell carcinomas.
Duct carcinoma over the pleomorphic adenoma of the parotid gland.
Epidemiologic profile of salivary gland neoplasms: analysis of cases
Although this current investigation was limited by a relatively small sample paritida, there was a long follow-up period in which we could verify and confirm the influence of some prognostic factors. Pleomorphic adenoma in unusual anatomic sites: Through a long follow-up period in present study was highlight the relevance of primary anatomical site, tumor size and metastasis as useful prognostic factors that may affect survival in patients with a primary diagnosis of head and neck mucoepidermoid carcinomas.
