Assessment Study to Evaluate Specific Immune Response in Locally Advanced Cervix Cancer After Radio-chemotherapy

Perspectives: * To set-up another clinical trial with this specific phenotype as the main stratification factor. Therefore a more aggressive or a more specific systemic treatment (with or without an immunomodulator) could be proposed to those selected patients in the field of personalized medicine. * To evaluate the use of the smear as a surrogate non-invasive technique to biopsy for immunomonitoring. * To use the CTC/PD-L1 assay as a liquid biopsy in future clinical trials for stratification and monitoring of cancer patients undergoing immune checkpoint treatments. This specific subset of CTCs might represent metastatic cells with a high potential to escape T cell-mediated lysis and might therefore be the actual targets of immunotherapy.
