[Reversed polarity high-cell carcinoma of the breast: A case report].

Reverse polarity high-cell carcinoma of the breast, formerly known as reverse polarity solid papillary carcinoma, is a rare entity recently introduced into the latest edition of the WHO classification of breast tumors. Its phenotype is triple-negative, and its diagnosis difficult. Although few cases have been reported in the literature, knowledge of this breast tumor is essential to distinguish it from other triple-negative carcinomas, which have a poorer prognosis.

Prevalence and Prognostic Value of HPV among Tunisian Patients with Laryngeal Cancer and Relationship between DNA HPV and p16, IGF-1R, Survivin, p53 Expressions.

Objectives: Tobacco and alcohol are the main etiological factors common to laryngeal cancers. However, the Human Papilloma Virus (HPV) constitutes an alternative risk factor according to several studies. In Tunisia, despite the annual increasing incidence of laryngeal squamous cell carcinoma (LSCC), the prevalence and prognostic significance of HPV have never been explored.

The Prognostic Significance of IGF-1R and the Predictive Risk Value of Circulating IGF-1 in Tunisian Patients with Laryngeal Carcinoma.

The aim was to evaluate the clinical impact of IGF-1/IGF-1R in Tunisian laryngeal carcinoma. A high IGF-1R immunohistochemical expression was found in our series (81.43%).

MARCKS protein overexpression is associated with poor prognosis in male breast cancer.

Background: Male breast cancer (MBC) is a rare and aggressive disease. Thus, identification of new therapeutic targets is crucial.

Objective: Our objective was to evaluate the protein expression of MARCKS (Myristoylated Alanine-Rich C-Kinase Substrate) in MBC and to investigate its prognostic value.
