Background
mCRC, toxicities, HFSR, hand‐foot skin reaction
METASTATIC COLORECTAL CANCER, HYPERTENSION
Fruquintinib has demonstrated significant improvement in overall survival (OS) among previously treated metastatic colorectal cancer (mCRC) patients. However, the utilization of fruquintinib has been constrained by various toxicities, such as hand‐foot skin reaction (HFSR) and hypertension, particularly in elderly patients with reduced tolerance to the standard dosage. This study aims to investigate the efficacy and safety of fruquintinib dose‐escalation strategy for elderly refractory mCRC patients.
