Ki-67 and p53 correlation prognostic value in squamous cell carcinomas of the oral cavity and tongue.

Unlabelled: Epidermoid carcinomas represent from 90% to 95% of oral cavity malignant neoplasias, making up 13,470 cases/year.

Aims: To correlate p53 and Ki-67 expressions in mouth and tongue carcinomas with lymph node status, gender, histological grade, tumor volume and pathological stage.

Materials And Methods: We carried out a retrospective study of 28 cases of mouth and tongue epidermoid carcinomas.

Prognostic value of the immunohistochemistry correlation of Ki-67 and p53 in squamous cell carcinomas of the larynx.

Unlabelled: Prognostic histological factors may contribute to determine the evolution of this neoplasia.

Aim: To correlate p53 and Ki-67 immunohistochemical expression with age, histological degree, lymph node involvement and pathological staging in patients with laryngeal epidermoid carcinomas.

Methods: We assessed thirty consecutive cases of laryngeal epidermoid carcinomas submitted to immunohistochemistry to check the expression of p53 e Ki-67 antibodies.
