This prospective, single-center, interventional study is conducted in order to achieve a biological bank accompanied by clinical data. Blood samples, optional tumor tissue and fecal samples are collected, processed and banked for all the included subjects. Those samples are collected before the start of treatment, at the time of first tumor assessment, at the time of first and second disease progression. The subjects are treated according to standard of care. Clinical data are collected at each sampling time. The primary objective of the study is to identify biological, clinical and tumoral factors associated with tumor response according SOC treatment.
Study Type
OBSERVATIONAL
Enrollment
500
additional biopsies will be performed during a diagnostic or therapeutic procedure, in order to sample tumor tissue and healthy tissue.
additional blood samples will be collected during a SOC sampling procedure (2 EDTA 7.5 ml tubes, 2 SST 7.5 ml tubes and 2 citrate 5 ml tubes)
constitutional and somatic genetic alterations will be analysed for subjects who consent, from either tumor or healthy tissue, or whole blood buffy coat after centrifugation
