Elastic staining – an rejuvenated method to reassess prognosis and serosal invasion in patients with pT3N0M0 gastric cancer

Prognosis of pT3N0M0 gastric cancer (GC) varies greatly, though the major factor conferring poor prognosis is unclear. Subserosal elastic lamina invasion (ELI+) is closely associated with poor outcomes in pT3 colorectal cancer, but related research on GC is unavailable. This study aimed to identify the influence of ELI+ on the prognosis of patients with pT3N0M0 GC and its relationship with serosal invasion using elastic staining. We retrospectively reviewed 94 and 28 patients with pT3N0M0 and pT4aN0M0 GC who underwent gastrectomy between 1994 and 2005.
