[Relative non curative resection of gastric cancer]

Relative non curative resection of gastric cancer was studied according to The General Rules of Japanese Research Society for gastric cancer. The five year survival rate was 31.2%, while 39.6% for relative curative resection and 4.9% for absolute non curative resection. The cases whose relative non curative factor was due to lymph nodes (n greater than R) resulted in a fair prognosis, but the prognosis of those concerned with peritoneal dissemination (P1) or liver metastasis (H1) was very poor. Surgical achievement to improve postoperative results may be obtained when a systemic (13), (14v) (16) lymph node dissection is performed whenever only one of them was involved in metastasis.
