Clinical Trial Summary

This trial is a prospective, monocentric, non-therapeutic, interventional cohort study aiming to decipher the immune TME through standard neoadjuvant CT in resectable G/GEJ adenocarcinomas. This study will also longitudinally monitor MRD during neoadjuvant and adjuvant therapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	evaluate in patient-derived tumor fragment (ex vivo platform of Centre Léon Bérard), the impact of immune checkpoint inhibitors (ICI) selected from our previous data in order to develop and improve therapeutic strategy		At least 36 months following inclusion
Other	assess MRD using liquid biopsies over standard neoadjuvant and adjuvant treatment.		At least 36 months following inclusion
Other	assess the correlation between ctDNA analysis and i) patient clinical outcome and ii) current prognostic factors (for instance TNM stage with ypTN stage in gastric and oesogastric junction carcinomas).		At least 36 months following inclusion
Primary	Describe Gastric and Gastroesophageal immunological tumor microenvironment	Spatial, spectral cytometry, and transcriptomic analyses	At least 36 months following inclusion
Secondary	Understand the evolution of the immune tumor microenvironment and its spatial structuration through standard neoadjuvant chemotherapy.		At least 36 months following inclusion
Secondary	Characterize the evolution of the immune tumor environment profiles and organization between responder and non-responder patients under standard neoadjuvant treatment.		At least 36 months following inclusion
Secondary	Characterize the immune profile in lymph nodes after surgery (lymphadenectomy) between responder and non-responder patients to neoadjuvant under standard neoadjuvant treatment.		At least 36 months following inclusion
Secondary	Assess the phenotype and functions of circulating immunes cells		At least 36 months following inclusion
Secondary	Perform integrative analysis combining spatial, molecular, single cell RNAseq, and spectral flow cytometry analysis on the immunological tumor environment in matched tumor tissues longitudinally		At least 36 months following inclusion
