[Epidemiological study, pathologic evaluation and prognostic factors of colorectal mucinous vs non-mucinous adenocarcinoma (a series of 196 patients)].

Background: Colorectal carcinoma is one of the main causes of cancer death in the worldwide with a decrease survival rate in relationship with a later diagnosis of advanced disease.

Aims: This study highlights the particular epidemiological, clinicopathological and immunohistochemical colorectal cancer profile. Indeed, our results differ markedly from that reported in the literature.

[P73 gene expression in colorectal adenocarcinoma: a prognostic or etiopathogenetic factor?].

Background: The p73 gene encodes a nuclear protein that is highy homologous to p53. p73 also shares some common functions with p53 protein indicating that p73 gene is a p53-like tumor suppressor.

Aim: In this study, we examined by immunohistochemestry the p73 expression on 120 cases of colorectal carcinomas and evaluated its implication in carcinogenesis.

Prevalence of celiac disease in Tunisia: mass-screening study in schoolchildren.
