The French multicentric molecular analysis platforms and personalized medicine trials MOST, MOST Plus and MEGAMOST.

BACKGROUND AND PURPOSE: In this manuscript we describe the academic French multicentric molecular analysis platforms including PROFILER, promoted by Centre Léon Berard, and the multicentric personalized medicine trials MOST, MOST Plus and MEGAMOST. PATIENTS/MATERIAL AND METHODS: MOST, MOST Plus and MEGAMOST comprise 14 cohorts with different targeted agents and immunotherapies. RESULTS AND INTERPRETATION: PROFILER has recruited 5,991 patients in 10 years, MOST and MOST Plus 875 patients since 2014 and MEGAMOST 172 patients since 2020, and are still ongoing. We provide a description of the local, national and international implications of these initiatives, and we review the results of the sorafenib and olaparib cohorts.
