ABSTRACT
Objective To investigate the method of establishing lymph node metastasis model for gastric cancer in nude mice.Methods Human poorly differentiated gastric cancer SGC-7901 ceils were cul- tured,inherited,amplified and collected in vitro,and were inoculated in nude mice subcu.taneously.After pas- saging six generations,the subcutaneous tumor was orthotopically implanted in nude mice.The mice were then sacrificed on the 9th week after implantation.Serum CEA density was detected using radio-immunity method. Orthotopically implanted tumors,remote organ metastases as well as lymph node metastasis were observed macrescopically and histologically.Results The successful rate of orthotopically transplantion of gastric can- cer was 100 %.The rate of perigastric lymph node metastases was 93.3 %.Local infiltration and remote metastasis were observed.The level of serum CEA in nude mice bearing tumor was significantly higher than that of normal nude mice(P
