Optimisation des techniques de chimiothérapie intracavitaire
2013
Introduction. In order to achieve a good effect, chemotherapy drugs need to penetrate into the peritoneal (HIPEC) or pleural tissue. Hyperthermia and high-pressure may enhance this penetration. The aim of this study was to evaluate their peritoneal effect and to establish the best technique to it. A feasibility study of an intrapleural high-pressure was an essential step to export these effects to the thoracic space. Methods. Four groups of pigs underwent an open HIPEC with a constant concentration (150 mg/l) of oxaliplatin during 30 minutes either in normothermia, or in hyperthermia (42-43°C); and either with atmospheric pressure or with high-pressure (25 cmH2O). Two more groups underwent …
L'hyperthermie provoque l'agrégation de FLIP et restaure l'apoptose induite par TRAIL
2014
The TNF-family member TRAIL (TNF-related apoptosis inducing ligand) is a cytokine involved in the immune anti-tumour surveillance. TRAIL is a promising agent currently under investigation for its anti-cancer properties with limited side effects on healthy cells. However, the use of TRAIL in oncology has been limited due to its lack of efficiency, mainly associated with cell resistance to apoptosis. The aim of this project was to study the interest of hyperthermia (or heat shock - HS) as an adjuvant for TRAIL therapy and the mechanisms involved in this sensitization.We have first evaluated the significance of this combination in a large variety of cancer cell lines known to be sensitive or r…
