Clinical effects of apatinib mesylate for treatment of multiple brain micrometastases:Two case reports

BACKGROUND Apatinib is a small-molecule multitargeted tyrosine kinase inhibitor.Apatinib has demonstrated encouraging antitumor activities.This study aimed to observe the efficacy and safety of apatinib for the treatment of multiple brain micrometastases.CASE SUMMARY We report two patients with multiple brain micrometastases after failure of second-line treatment.Both patients had extracerebral metastases.When the patients took 250 mg/d apatinib orally,the intracerebral lesions disappeared.The extracerebral lesions were partially alleviated.Both patients had a progressionfree survival of more than 12 mo and were still stable.The safety was good.The main adverse events(AEs)were mild hypertension and proteinuria,which could be controlled.CONCLUSION Apatinib has clear efficacy and good tolerance in patients with multiple brain micrometastases after failure of second-line treatment.
