Patients with histologically confirmed metastatic or unresectable MSS/MSI-L/pMMR colorectal adenocarcinoma refractory to or intolerant of fluorouracil, oxaliplatin and irinotecan based systemic treatment, were enrolled in the study. All patients will receive a third line therapy with fruquintinib and anti-PD-1 antibody. Clinical and radiographic assessment will be performed regularly. Patients will be treated until disease progression, untolerable toxicity or withdrawal of consent.
This study was an observational cohort study to investigate the efficacy predictors of fuquinitinib combined with anti-PD-1 monoclonal antibody for third-line treatment and above in Chinese patients with advanced colorectal cancer.
