Prognosis Of Patients With Resection Of Stage Iv Gastric Cancer
INTERNATIONAL SURGERY(1998)
摘要
We retrospectively analyzed 116 patients who underwent resection of stage IV gastric cancer to investigate the prognostic factors responsible for long-term survival, Statistically significant clinicopathological differences between patients surviving 3 years or more (n = 9) and those surviving less than 3 years (n = 107) were observed in regard to macroscopic type, curability of surgery, lymph node metastasis and blood vessel invasion. These four variables also had a statistically significant influence on survival by univariate analysis, Multivariate analysis revealed that no residual tumor (R0) surgery was a significantly beneficial factor for long-term survival. However, no patients with the diffusely infiltrative type of tumor survived for more than 2 years even if they underwent R0 surgery. Patients without the diffusely infiltrative type who underwent R0 surgery had better survival rates: a 27.3% and 13.6%, 3 and 5 year survival rate, respectively. In conclusion, R0 surgery contributes to long-term survival even in stage TV gastric cancer, and some patients with the not diffusely infiltrative type, in particular, may receive a survival benefit by R0 surgery.
