Objective: To evaluate the short-term efficacy and toxicity of endostar in combination with XELIRI as the second-line treatment for advanced colorectal cancer.
Methods: Twenty-one patients with advanced colorectal cancer were treated with intravenous infusion of endostar (15 mg/day for 14 consecutive days) and irinotecan (250 mg/m(2), single dose on the first day), and oral administration of capecitabine (1.0 mg/m(2), twice daily for 14 days), and the treatment cycle was repeated every 21 days. The efficacy and toxicity of the treatments were evaluated according to RECIST and NCI-CTCAE3.0 standard, respectively.
Results: The overall response rate was 9.5% in these patients, with a median time to progression (mTTP) of 3.9 months. The main adverse effects associated with the treatment included leucopenia, nausea/vomiting and peripheral neuritis.
Conclusion: Endostar combined with XELIRI is effective and safe as the second-line treatment for advanced colorectal cancer, and further clinical investigation is warranted.
