Recent scientific advances have shown the important role of immune system against cancer. Today, many immunological biotherapy like anti-PD1/PDL-1 are available in cancer treatment and generate durable clinical responses in some patients. The development of tools for monitoring anti-tumor immune responses dynamically is a major challenge to predict the effectiveness of immunotherapies anti-PD-1 and anti-PDL-1.
Thus, the objective of our study is to analyse the interest of the monitoring of anti-telomerase T helper 1 (TH1) responses in predicting the efficacy of immunotherapy, using an immunoassay developed by our group.

Experimental: Biological samples
Blood samples will be realized specifically to the study at inclusion (baseline before starting anti PD1/PDL1 treatment), and then 1 month, 3 months and 12 months after initiation of anti-PD1/PDL1 treatment.
Peripheral blood mononuclear cells (PBMC) and plasma will be collected.
Available tumor tissues will be collected.
Other: Biological samples
blood and tumor tissue samples
Drug: Anti PD1/PDL1 treatment
- anti-telomerase specific Th1 responses [ Time Frame: up to 12 months after the initiation of anti-PD1/PDL1 therapy ]measured by ELISPOT assay
- objective response rate [ Time Frame: up to 12 months after the initiation of anti-PD1/PDL1 therapy ]according to RECIST v1.1 criteria
