Abstract:
e15003 Background: Colorectal cancer is the third most frequent cancer and the fourth most frequent cause of cancer-related death worldwide.25% of patients with colorectal cancer have metastatic disease which leads a clinically significant detrimental effect on prognosis. After failure of standard treatments, regorafinib will be recommended to patients, but it has not been approved in China now. Apatinib is a novel, small-molecule tyrosine kinase inhibitor of VEGFR-2 which has shown a survival benefit in gastric cancer in a Phase III trial. This study is an initial clinical experience about the efficacy and safety of apatinib in patients with metastatic colorectal cancer refractory to standard therapies. Methods: Patients with refractory metastatic colorectal cancer received apatinib 500mg once daily. A treatment cycle was defined as 28 days (4 weeks). Response was assessed using RECIST 1.1 criteria. Toxicity was recorded using CTCAE version 4.0. Results: Between August 2015 to October 2016, seventeen patients were enrolled. One patient had PR (5.9%),twelve patients had SD (70.6%), and four had PD (23.6%). The ORR was 5.9% and DCR was 76.5%. The median PFS was 125 days (4.0months, 95%,CI = 1.1-6.9). The grade3/4 adverse events were hypertension (2/17;11.8%), proteinuria (2/17;11.8%), Hand-foot syndrome (2/17;11.8%), leukopenia(1/17;5.9%), neutropenia(1/17;5.9%), hyperbilirubinemia(1/17;5.9%), and diarrhea(1/17;5.9%),respectively.There were no treatment-related deaths. Conclusions:Apatinib is active for the treatment of refractory metastatic colorectal cancer with a manageable tolerability profile. Further investigations of apatinib in mCRC are needed.
