Possible explanations could be that: (1) elevated KIF2A expression was associated with unfavorable disease features as mentioned above, which might indirectly cause shorter OS; (2) KIF2A might facilitate GC cell invasion by promoting membrane‐type 1 matrix metalloproteinase,11 which might subsequently influence progression after surgery and result in worse OS; (3) KIF2A might affect chemosensitivity after surgery and further influence OS.25 The gene discussed is KIF2A; the disease is gastric cancer.
