Epidemiology of Gastric Cancerin Mainland China & In Greater Shanghai
Overall morbidity is declining
Absolute number of pts is large
Newly diagnosed GC in Shanghai > 6000 /Yr
Biological behavior is more aggressive in recent cases

Translational Research to Improve the Outcome of Gastric Cancer Patients
• New Techniques for early diagnosis of gastri
c cancer
• Pre-operative staging
• Intra-operative peritoneal hyperthermic chem
otherapy( IPHC)
• Multi-modality treatment of gastric cancer ac
cording to different stages

Improvement of Results Due to
• Increase in ratio of Early & Middle-Stage cases
• Close follow-up of high risk persons
• Close cooperation between Gastroenterologists &
Surgeons
• Probing new parameters
• Adoption of a more rational strategy

A comparative study on the efficacy of splee-preserving modified D2 radical gastrectomy and D2 radical
gastrectomy with splenectomy
Conclusion: The efficacy of modified D2 radical total gastrectomy
with spleen-preserving for patients with gastric cancer in the upper third, upper and middle third or entire stomach is similar to that of D2 radical total gastrectomy with splenectomy, and the spleen-preserving procedure is associated with decreased postoperative complication and improved survival.
