Third-line treatment for metastatic colorectal cancer: anlotinib is superior to chemotherapy and similar to fruquintinib or regorafenib

Year, pages: 2020, 1384 - 1390

The clinical efficiency and adverse reactions of anlotinib in metastatic colorectal cancer (mCRC) as a third-line treatment compared with chemotherapy and regorafenib or fruquintinib was explored in this study. Clinical data from 105 mCRC patients who failed at least two lines of chemotherapy were collected. The patients were divided into three groups based on their third-line therapeutic regimen: third-line chemotherapy only (group A); anlotinib (group B); and fruquintinib or regorafenib (group C). The result showed that the ORR and DCR of group B (14.29%, 85.71%) were higher than those of group A (0%, 40.00%). The ORRs of group B and group C were 14.29% and 20.00%, respectively. Group B and group C had the same DCR, 85.71%. The mean PFS values of group B (3.46 months) and group C (3.33 months) were longer than that of group A (2.25 months) (χ2=84.255, p<0.001) and the mean PFS values of group B and group C were similar (χ2=0.884, p=0.347). The mean OS of group B was 9.22 months, which was longer than that of group A (6.95 months) (χ2=38.837, p<0.001). The mean OS values of group B (9.22 months) and group C (9.38 months) were not significantly different (χ2=0.456, p=0.499). The incidences of proteinuria, hand-foot skin reaction, myelosuppression, and gastrointestinal reaction were similar between group B and group C (p=0.173, 0.188, 1.00, 0.154, respectively). Myelosuppression and gastrointestinal reaction were more common in group A than in group B and group C (p<0.001). For mCRC, anlotinib as a third-line treatment is better than chemotherapy and similar to regorafenib or fruquintinib. The associated adverse reactions are tolerable.
