Overview
Accumulating evidence indicates that patient- derived organoids (PDOs) can predict drug responses in the clinic. Metastasis is the main cause of death in colorectal cancer patients, and the treatment of patients with liver metastasis remains poor. Tumor heterogeneity is the cause of treatment failure. In this study, we aim the investigate the consistency of drug sensitivity for the matched primary and metastatic tumor in patients with liver metastasis.
