Prognostic value of surgical margin status in gastric cancer patients

Abstract

Surgical margin status is an independent prognostic factor for GC. Patients with positive margin have a poor prognosis, similar to that of IIIc stage disease. When the tumour demonstrates infiltrative growth pattern (Borrmann type III and IV) and the surgical margin status is difficult to determine, extended gastrectomy should be implemented to ensure an R0 resection. Those high-risk patients should be considered for postoperative chemotherapy.
