Post-doctoral position


 Glioblastoma is the most frequent primary malignant tumor of the central nervous system and represents 2,000 to 2,500 new cases per year in France. The optimal treatment is multimodal: it is based on the combination of a first resection of the tumor (when this is possible), followed by radiotherapy on the operating bed (or the tumor in the absence of initial resection) coupled with chemotherapy followed by maintenance chemotherapy. Despite this standard treatment, tumor recurrence, commonly called cancer progression, is the rule. 


 In this context, the objective of the work is twofold: (i) to establish a simple process making it possible to import into a common database and process data from routine imaging (MRI), tumor sequencing (analyzes of molecular biology) and the clinic in order to build a tri-modal database; and (ii) develop machine learning based algorithms for predicting progression (topography and delay) from this tri-modal basis for patients with newly diagnosed glioblastoma. Finally, an IT platform will be implemented to include all the necessary operations related to these two objectives. We are conducting the project in close collaboration with the Center of Cancer Research - Henri Becquerel Center in Rouen, where the IT platform will be installed for physicians.
