Etude des mécanismes d'action d'une immunothérapie par un lipide A, seul ou associé à l'oxaliplatine, dans des modèles de cancers coliques

2013

Colorectal cancer is a major public health concern in France. Resistance to standard chemotherapy requires development of novel therapeutic approaches. In the past decades, our team showed the immunotherapeutic properties of lipid A in a model of colon cancer in rats. 95% of rats bearing small carcinomas were cured following treatment by lipid A. The study of mechanisms underlying this immunotherapy allowed us to show that the antitumor effect of lipid A was dependent on cytotoxicity induced by granzyme B produced by intratumoral neutrophils. Indeed, we have shown that, in the tumor microenvironment, neutrophils produced granzyme B and had a pro-tumorigenic N2 phenotype. When rats were trea…

Rôle de l’hypotonie dans la réponse à la chimiothérapie intra-péritonéale : étude des effets sur les cellules cancéreuses et la mort immunogène indui…

IntraPeritoneal Chemotherapy (IPEC) is commonly used to treat colorectal cancer metastases. However there is no standardized protocol.The aim of this work was to model this chemotherapy in vitro and to understand the role of hypotonic conditions in this model and its impact on cell death.We determined that the optimal treatment parameters on HCT116 human colon cancer cells, were an exposure of the cells for 30 minutes to 400μM of oxaliplatin under hypotonic conditions (G2.5%) at 37 °C. These results have been validated on various human and murine colic cancer cell lines. We have also shown that these treatment conditions are also able to increase the cytotoxicity of other platinum derivativ…

Hypersensibilité immédiate au carboplatine ou à l’oxaliplatine : réintroduction du cisplatine sans tests cutané ?

2017

International audience; Introduction : L’incidence des réactions d’hypersensibilité immédiate aux sels de platine (cisplatine, carboplatine et oxaliplatine) augmente avec leur large utilisation en cancérologie. Les objectifs de cette étude étaient d’établir la fréquence des sensibilités croisées entre les sels de platine, de déterminer si le cisplatine peut être utilisé sans test allergologique préalable en cas d’allergie immédiate au carboplatine ou à l’oxaliplatine et enfin de proposer une prise en charge simple pour retraiter rapidement les malades.Méthodes : Notre étude rétrospective a porté sur 155 malades ayant présenté une réaction d’hypersensibilité immédiate à un sel de platine. De…
