Texto completo da fonteDigestive cancers are among the most common cancers, with a high mortality rate. They most often develop from a benign lesion that slowly evolves and eventually becomes cancerous. Organized screening by endoscopy increases the chances of cure, thanks to early detection and treatment. With recent optical advances in endoscopic imaging, a wide variety of lesions can be visualized during colonoscopic examinations. We first demonstrated that, once detected, colorectal lesions need to be characterized in order to predict histology in real time during endoscopy and choose the best therapeutic option for each lesion. Biopsies (targeted or not) are unnecessary and may make subsequent resection more difficult. The many existing classifications have their limitations, however, and we have therefore merged the criteria of all the usual classifications into the CONECCT classification, which in a prospective evaluation demonstrated its good diagnostic performance, enabling appropriate treatment choices to be made for lesions. We then sought to develop the initial CONECCT classification, by adding lesions with a focal zone of deep invasion, showing that diagnostic submucosal dissection is feasible for these lesions, and by adding colonic submucosal lesions, showing that as most are not malignant, they do not warrant advanced endoscopic resection but could benefit from a step-up strategy starting with simple histological sampling with advanced resection for the rare malignant lesions in a second stage. As lesion degeneration is not homogeneous, we sought to improve detection of areas of interest by showing that an area stained green in virtual chromoendoscopy, or green sign, could be associated with a more pejorative lesion histology. All the more so as we have described the difficulty presented by AI systems in detecting flat lesions such as sessile serrated lesions and non-granular laterally spreading tumors. As the characterization of colorectal lesions is essential but very difficult, we then sought to improve the characterization training of French-speaking gastroenterologists, via a working group on a social network, featuring educational videos dedicated to characterization. However, passive use of the group, with a very low degree of user interaction, failed to show any progression among residents over one year. Finally, we have developed a free application on computer and smartphone, enabling collaborative characterization by a trio of experts of 20 colorectal lesions published by 12 gastroenterologists

Texto completo da fonteAlmost 20% of cancers are due to a viral, bacterial or parasitic infection. For instance, Cryptosporidium parvum (C. parvum) was found to induce the development of an invasive digestive adenocarcinomas in an experimental model of SCID mice.However, the understanding of the pathogenesis of Cryptosporidium has been limited by the lack of a long-term culture system. It is therefore essential to improve the in vitro culture systems by trying to mimic the in vivo conditions. Firstly, the association between Cryptosporidium infection and cancer development was investigated through an epidemiological study among cohorts of Lebanese patients with or without recent diagnosis of digestive cancer before any treatment. A high rate of Cryptosporidium was detected in biopsies from Lebanese patients with digestive neoplasia/adenocarcinoma. These results showed that Cryptosporidium is associated with human colon cancer being maybe a potential etiological agent of this disease. In the second part, a three dimensional (3D) Cryptosporidium culture model was developed from adult murine colon. This system allowed the reproduction of neoplasic lesions at 27 days post-infection, providing new evidence of the role of the parasite in the induction of carcinogenesis. This is the first description of a low-grade intraepithelial neoplasia induction after parasite infection in a 3D culture. Finally, in order to automatize the culture, a microfluidics device for explant culture was designed. An explant culture was maintained for almost 8 days using this microfluidic device. To our knowledge, this is the first description of a gut tissue culture on a microfluidic device that was viable for 8 days

Texto completo da fonteImportant changes have occurred in the epidemiology of rare digestive cancers. It is difficult to obtain unbiased data to study the epidemiology of those cancers. Population-based studies recording all cases in a well-defined population represent the only way to assess this disquieting situation. Thus the objective of this study was to examine trends in incidence prognosis and socio economical disparities to improve the epidemiological knowledge of these cancers. The prognosis in the general population is considerably worse than is often reported from small hospital case series. Early diagnosis is difficult: new therapeutic options appear to represent the best approach to improved prognosis. All cancers were characterised by a sharp increase of incidence over the past years, both by period and birth cohort, but the most important rise was for oesophageal adenocarcinoma. Etiological studies still necessary to understand the reasons of such a rise

Texto completo da fontePolyphenols are the most widely occuring microconstituent family of our diet. Animal studies as well as some epidemiological data show an inverse association between the high intake of some popyphenol classes and the incidence of evolutive diseases such as atherosclerosis and cancer. Biological effects of a molecule depend on its bioavailability, and polyphenol bioavailability remains obscure. In the present work, two determinant aspects of bioavailabilty have been investigated: 1) Stability during gastro-intestinal digestion. In vitro acellular studies have shown that polyphenol stability depends on their molecular structure. Moreover, it has been observed that polyphenols are able to protect other classes of dietary antioxidants (vitamin E and carotenoids) from oxidation in the upper digestive tract. These results could explain the of some supplementation studies. 2) Absorption and metabolism by enterocytes. Absorption studies across differentiated Caco-2/TC7 cells have been performed with two frequently dietary occurring molecules, vanillin and naringin. Data displayed that transport and metabolism mechanisms depend on the structure, and several metabolites have been identified. Weak absorption of naringin and extensive metabolism of vanillin by enterocytes are responsible of the poor intestinal absorption of these compounds. Taken together, these data could contribute to the elucidation of the in vivo biological effects of polyphenols
