Tanigawa et al classify cancer in the remnant stomach into three categories: 1) cancer newly developed in the remnant stomach, 2) cancer remaining in the remnant stomach at the initial gastric surgery, 3) and recurrent cancer in the remnant stomach.
Cancer newly developed in the remnant stomach after partial gastrectomy is worthy of attention not only because it is a typical model of carcinogenesis but also from the aspect of cancer diagnosis.
Long term survival results after the second surgery clearly demonstrated that surgical treatment for CRS was as effective as that for primary cancer in the upper stomach ( PUC ). The 5 year cumulative survival rate was 56% for the patients with CRS and 53% for those with PUC in whom curative surgery was achieved. In addition it was confirmed that new lymphatic drainage into the lower mediastinum or the jejunal mesentery had developed after the initial gastric surgery.
Newman et al. agree that the outcome following resection of Gastric Remnant Carcinoma is no different from that of other primary proximal gastric cancers of the same stage.
Kondo suggests that recently the population at risk of gastric stump carcinoma for benign disease has been diminishing significantly, and the incidence of gastric stump carcinoma after surgery for malignant disease has been increasing ( 3 ).
