简要总结
The immune system may be involved in the recognition and destruction of tumor cells or cells undergoing transformation. It is also currently accepted that the quality of immune responses can influence the evolution of cancers after chemotherapy.
In this context, it is possible to assess the presence of specific T cells in patients' blood and to correlate the presence of specific memory lymphocytes with the quality of long-term clinical protection.
The analysis of immune responses can also be based on i) analysis of the tumor microenvironment (analysis of surgical samples or biopsies) or ii) analysis of molecules secreted in plasma.
Today, the immunotherapies can generate clinical responses in several cancers (for 15 to 25% of patients with melanomas, bladder, lung, kidney or gastric cancers). But the development of these drugs raises two unresolved questions: i) what immunological parameters predict the efficacy of these treatments? ii) why do some cancers remain refractory to the efficacy of these immunomodulatory drugs? It is therefore necessary to identify biomarkers for prognostic stratification and monitoring of patients treated by immunotherapy.
The primary objective of our research team is to identify biomarkers related to the immune system or tumor microenvironment in order to better define patient eligibility criteria for immunotherapy strategies.

结局指标
主要结局
for cohorts A and B: Progression free survival (PFS) at 6 months post treatment initiation
时间窗: 6 months post treatment initiation
Progression free survival (PFS) at 6 months post treatment initiation, defined as: * non progressive alive patients: if patients are alive without progression in the 6 months from the date of treatment initiation * or progressive or death patients: if patients are identified with a progression or a death in the 6 months from the date of treatment initiation * patients without progression or death and with follow up bellow than 6 months are not assessable for PFS status at 6 months Progression-free survival (PFS): defined as the delay from the date of treatment initiation to the disease progression or death from any cause whichever occurs first. Alive patient without progression will be censored at last radiological evaluation available showing no progression.
For cohort C: Relapse free survival (RFS) at 6 months after surgery of metastases
时间窗: 6 months after surgery of metastases
RFS: defined as the delay from the date of surgery of metastases to the disease relapse or death from any cause whichever occurs first. Alive patient without relapse will be censored at last radiological evaluation available showing no relapse.
