Brief Summary
The proposal is to conduct a prospective, multi-cohort study aiming to decipher molecular profiles/biological characteristics of advanced cancer patients during the course of their disease with longitudinal and sequential analyses of tumor and liquid biopsies. This approach will allow i) to develop a model in order to predict tumor response / resistance in real life conditions and to better understand adaptive mechanisms and ii) to potentially propose therapeutic options to enrolled patients following the review of the biological/molecular data generated during this study and during a Molecular Tumor Board in case of disease progression. This study will include 12 cohorts according to tumor type and standard treatment received (See Inclusion criteria I1). Patient will be enrolled before the initiation of standard anti-cancer treatment.

Outcome Measures
Primary Outcomes (6)
Number of patients with meaningful molecular genetic alterations on tumor sample
Identification of molecular genetic alterations based on molecular characterisation (WES and RNASeq) of tumor at diagnosis, then under standard anti-cancer treatment : treatment start, 1st radiological evaluation and disease progression
At the end of study (4 years)
Number of patients with meaningful molecular genetic alterations on circulating tumour DNA (ctDNA)
Identification of molecular genetic alterations based on molecular characterisation (WES and RNASeq) of ctDNA under standard anti-cancer treatment : treatment start, each radiological evaluation and disease progression
At the end of study (4 years)
Number of patients with meaningful immunological features
Identification and characterisation of the tumor microenvironment and the host's immunological profile, at diagnosis and during patient treatment
At the end of study (4 years)
Objective Response Rate (ORR) as per RECIST V1.1 and according to central review
For solid tumors excluding glioblastoma only
3 months
Progression-Free Survival (PFS)
For glioblastoma only
6 months
Objective Response Rate (ORR) according to iwCLL criteria
For chronic lymphocytic leukemia
6 months
Secondary Outcomes (10)
Correlation between disease evolution and molecular and/or immunological biomarkers
Time Frame: up to 4 years
Evaluation of circulating-tumor DNA (ctDNA; liquid biopsy) yields similar genomic profile as the tumor sample.
48 months
Number of patients with recommended therapy according to biological data (liquid versus tumor biopsy)
48 months
Tumor characteristics using a radiomic approach and detailed analyses of imaging.
48 months
FACT-G questionnaire
48 months
- +5 more secondary outcomes
