Clinical significance of dissection of superior mesenteric vein 14v group lymph node in gastric cancer metastasis / 重庆医学

ABSTRACT

Objective Through investigate dissection of 14v group lymph node of patients with gastric cancer and its metastasis , to explore the influence factors and prognosis of dissection of 14v group lymph node .Methods 120 cases of gastric cancer patients who underwent radical gastrectomy and dissected 14v group lymph node since Mar .2004 to Mar .2012 were analyzed ,through his-topathological and immunohistochemical examination to detect the 14v group lymph node metastasis and calculation .Results Gas-tric antrum carcinoma were detected 176 nodes ,29 nodes were metastasis ,but there were none in other places .About TNM classifi-cation ,14v group lymph node metastasis among patients in stage Ⅳ(5 cases) was 50 .0% ,in stage ⅢC(7 cases)was 33 .3% ;About Borrmann classification ,14v group lymph node metastasis among patients in borrmann type Ⅳ (4cases) was 80 .0% ,in stage Ⅲ(11cases) was 30 .6% ,which were higher than that of other types(P<0 .05) .Among the 18 cases which had 14v group lymph node metastasis ,15 cases(83 .3% )invaded serosa ,invading the surrounding organs .The 5 year rate of 14v group metastasis patients was 7 .7% .Conclusion Gastric carcinoma tumor size ,tumor stage ,Borrmann classification ,invading the surrounding organs and tissues and metastasis in 14v group lymph node have a certain relationship .14v lymph node dissection for lately TNM stage gastric tumor has no certain significance .
