  • Metastatic Colorectal Adenocarcinoma

Interventions

DRUG

TKI ± anti-PD-1 antibody

After one cycle of TKI, evaluations would be performed according to RECIST v 1.1. (1) obvious response (A): CR, PR or shrunken SD, or cavitation in metastatic lung lesions, or decrease in the density of liver metastatic targets ≥15%; (2) general response (B): enlarged SD; (3) poor response (C): PD. TKI ＋ anti-PD-1 antibody will be administered in group A. The subjects in group C will exit the study. The subjects in group B will continue TKI for another one cycle, the obvious response subjects will entered group A, the general response subjects will keep in arm B and continue the TKI monotherapy, and the poor response subjects will exit the study. 1. Fruquintinib 5mg or regorafenib 120mg, qd po, 3 weeks, Q4w. (The investigators decide to choose fruquintinib or regorafenib) 2. Toripalimab injection 240mg, Q3w, until the disease progresses or lasts for two years.
