Distribution of T-cell subsects in regional lymph node nodes have studied using the monoclonal antibody (Leu-series). Lymph nodes have little immunological resistance against cancer cells. Aggressive lymph node removal should be necessary in gastric cancer.
The peritoneal dissemination was more frequently observed in the younger patients than in older in both differentiated (diff.) and undifferentiated (undiff.) gastric cancer. Similar prevalence was also observed in lymph node metastasis of undiff. cancer but not in that of diff. type. In younger patients, more radical lymph node surgery should be performed.
Improved survivals with increasing degree of lymphatic resection have been shown only in the prognostic serosal factor negative patients and positive cases should be treated by all kinds of therapies such as hyperthermia, adjuvant immunochemitherapy, more aggressive surgery based on biological findings.
