Efficacy and Safety of Regorafenib Maintenance Therapy in Patients With Metastatic Colorectal Cancer (mCRC)

Regorafenib in third-line treatment of metastatic colorectal cancer(mCRC) significantly prolongs the survival of patients, and its advancement has a sensitizing effect on postline chemotherapy and thus improves the prognosis of patients. Therefore, the present study was designed to include patients who achieved stable disease/partial response(SD/PR) after 3 months of second-line therapy and advance regorafenib to investigate the role of advance regorafenib in prolonging progression-free survival, prolonging the efficacy of overall survival, safety, and quality of life in patients with mCRC compared with standard second-line and third-line therapy.
