Metastatic Colorectal Cancer
Conditions
Brief summary
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 OncoImmunology 2012 and unpublished data).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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival | date of first progression of the disease (within 3 years after the enrollment in the study)] | time interval between the date of initiation of treatment and the date of first progression (local, remote \[extent of the disease by RECIST v1.1\] second cancer) or death from any cause. |
