After having constituted the ORTRAI cohort using the CONSORE database at the Jean PERRIN Center, the objective is to characterize the patients both clinically and biologically, histologically and genomically.

The clinical and biological characterizations will allow us to confirm that our cohort is comparable with data from the literature.

The complement of immunohistochemical and molecular analyses will provide more details on the differences between long-term patients responding to treatment and refractory patients.
