简要总结
The investigators recently identified promiscuous HLA-DR-derived epitopes from the human telomerase reverse transcriptase (TERT) called universal cancer peptides (UCP), to study tumor-specific CD4+ T cell responses.
The investigators found high frequency of naturally occuring UCP-specific TH1 cells in long term survival of metastatic colorectal cancer (CRC) previously treated by 5 fluoro-uracil -oxaliplatin (Folfox) +/- bevacizumab regiment (Godet et al. OncoImmunology 2012 and unpublished data).
Epitopes-CRC02 is a French prospective multicenter study which will evaluate the post chemotherapy and post surgery modulation of host tumor-specific CD4 TH1 cell responses in metastatic colorectal cancer patients and their correlation with progression-free survival.

研究组 & 干预措施
Additional biological samples
Additional blood samples will be realized specifically to the study at baseline, at 1 month, at 3 months, and 1 month after surgery (if applicable).
Peripheral Blood Mononuclear Cell (PBMC) and plasma will be collected. Tissue tumor is collected during surgery if applicable.
干预措施: Additional biological samples (Other)
结局指标
主要结局
