[Significance of extended radical operation for advanced gastric cancer of stage IV].

The significance of extended radical operation (gastric resection with R3 and paraaortic lymph-node mean value of R4 dissection) was retrospectively studied in 1,363 cases (1968-1987) of advanced gastric cancer in Stage IV. For liver metastasis, gastric and R2 lymph node resection with transcatheter arterial embolization or chemoembolization was superior to liver resection. The operative results showed that 5-year survival rate of radical dissection of RO-2 was 19.3% and that of R3-4 was 34.6% (p less than 0.05). It also suggested that the operation was effective in 78% of patients with POHO and POHO, ow(-) and aw(-). As a conclusion, extended radical operation is significant as the treatment of advanced gastric cancer in Stage IV.
