In this case report, the combination of apatinib and TMZ exerted good efficacy and safety in the treatment of a melanoma patient with KIT mutation in exon 11, who had progressed after the second-line chemotherapy. As NGS analysis did not find any other gene mutations, KIT might be the patient’s driver gene, suggesting that routine screening of acral melanoma for KIT mutation may open up new treatment choice for those patients. Considering apatinib has multiple mechanisms in anti-tumor effect, it is possible that apatinib plus TMZ might be a feasible option in metastatic melanoma with KITmutation in exon 11. Large prospective trials are needed to confirm the efficacy and safety of apatinib and TMZ combination therapy for MM treatment in the future.
We thank the patient for his participation and his agreement and written informed consent for publication of his information and accompanying images in this case report. We also thank Burning Rock Biotech for doing NGS analysis.
