The percentage of gastric tumours that are positive for VEGF-C protein expression varies from 26 to 51% (Table 2) (Yonemura et al, 1999; Ichikura et al, 2001; Kabashima et al, 2001; Takahashi et al, 2002), although this may be accounted for in part by the use of varying methodology as discussed. The gene discussed is VEGFC; the disease is gastric neoplasm.
