3. Autologous effector T-cells administration will be performed at D7. Efficacy will be assessed through tumor size change. Change in tumor size will be assessed with CTscans (RECIST criteria), MRIs (functional criteria following injection: DCEMRI and diffusion MRI to assess change in cellularity and tumor necrosis and morphological criteria RECIST), and sonography with contrast injection (to assess vascular microcirculation). Assessments will be done prior to lymphoid-ablation and then monthly for 9 months. Safety will be systematically assessed daily during in-patient period using the World Health Organisation - Common Toxicity Criteria (WHO-CTC).
