revert - targeted therapy for advanced colorectal cancer patients

Conditions: Metastatic Colon Cancer

Summary: this is a clinical prospective, no-profit, interventional, premarket medical device "early phase", multicentre, single-arm study, based on collecting data on predictive biomarkers of mcrc patients, integrate them with the results of the retrospective evaluation of outcomes and profiles of historical mcrc patients previously treated in the oncology units, in order to evaluate the efficacy of the best administered treatment. results from the retrospective evaluation, will serve to build an ai-based profile capable to identify "good" or "poor" responders to therapy and to support the clinician towards the best treatment option. ai is a software based on algorithm defined as medical device class iia.
