Analysis of long-term results of radical gastrectomy combining splenectomy for gastric cancer / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the influence of radical excision combining splenectomy on prognosis of the patients with gastric cancer.</p><p><b>METHODS</b>Between June 1994 and March 2004, 692 patients were operated on for gastric cancer and registered into gastric cancer database. Radical excision (D2, D3 or D4) combining splenectomy for gastric cancer was performed in 45 cases. 343 cases were selected simultaneously for comparison according to the resembling rules in sex, age, tumor size, location, serosa invasion, Borrmann type and range of lymph node dissection. Clinicopathological factors affecting lymph node metastasis, patterns of lymph node metastasis, 5-year survival rate after radical excision combined with splenectomy for gastric cancer were compared.</p><p><b>RESULTS</b>Lymph node metastasis rate of splenic hilus was 15.6 percent. Among them, upper, middle and lower domain is 11.5 percent, 33.3 percent and zero respectively. It was significantly different between gastric adenocarcinoma in proximal and body of stomach and that in distal stomach, poor differentiation and adenocarcinoma anaplastic and well and moderately differentiation adenocarcinoma, Borrmann III and IV types and Borrmann I and II types, infiltrated depth in T(3) and T(4) and infiltrated depth in T(1) and T(2), clinical stages III and IV and clinical stages I and II. The average and median survival time between radical gastrectomy only and radical gastrectomy combining splenectomy for gastric cancer at stage I and II patients were significantly different, but at stage III and IV patients not significantly different.</p><p><b>CONCLUSIONS</b>Spleen should be reserved for patients with gastric cancer at stage I and II, and radical excision combining splenectomy could only be performed at stage III and IV patients with cancer infiltrating body and tail of the pancreas, or lymph nodes metastasis in the splenic hilus. Indication of radical excision combining splenectomy for gastric cancer must be further study to clarify its efficacy.</p>
