چکیده

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. RESULTS Mean age was of 56.2 years and the immunoexpression of the markers was observed in the group with more than 50 years of age, especially that o the ki-67 antibody (p=0.032). There was no relation between p53 and Ki-67 with lymph node involvement. Ki-67 was expressed in 70% of the high histology level cases and in 80% in the low histology ones; while p53 was of 70% only in the high level cases. Pathology staging showed that in the group of advanced carcinomas, p53 expression was of 61.5%, while Ki-67 proved positive for the early cases (100%) and advanced (73.1%). CONCLUSION There were no significant differences between p53 and Ki-67 immunoexpression in laryngeal epidermoid carcinoma, except in the group of patients with more than 50 years of age, when Ki-67 expression was significantly higher.

Background: Fine-needle aspiration of breast cancer often provides moderate cellular material that is representative of the tumors. These samples can be used not only for cytological diagnosis but also to obtain information on the prognosis and likely response to therapy by using immunohistochemical staining studies. Methods: We assessed the degree of correlation between prognostic biologic ma...

Mutations of p53 Gene in Skin Cancers: a Case Control Study

Background: The most frequently mutated tumor suppressor gene found in human cancer is p53. In a normal situation, p53 is activated upon the induction of DNA damage to either arrest the cell cycle or to induce apoptosis. However, when mutated, p53 is no longer able to properly accomplish these functions. The aim of this study was to investigate the expression of p53 gene in cases of skin cancer...

Evaluation of Nuclear Morphometry and Ki-67 Index in Clear Cell Renal Cell Carcinomas: a Five‌-Year Study

Background and objective: Clear Cell Renal Cell Carcinoma (CCRCC) is the most common adult renal neoplasm. Staging and grading of RCC are important predictors of survival. Fuhrman nuclear grading is widely used for CCRCC, the subjective nature of which has prompted more objective methods to evaluate nuclear features. Furthermore, Ki-67, a reliable marker of cellular pr...

P53 and Ki67 protein expression in ocular squamous cell carcinomas of dairy cattle

Role of the protein overexpression is very important in the pathogenesis, diagnosis and prognosis of neoplasia. Cases of overexpression of p53 and Ki67 proteins were investigated in 19 ocular squamous cell carcinomas (OSCC) in dairy cows. Microscopically, insix cases the tumors were carcinoma in situ (noninvasive carcinoma, G0), and in the remaining 13 cases the tumors were invasive carcinoma. ...
