Abstract

Background and objectives: The indication for splenectomy in proximal gastric cancer remains controversial. Splenectomy is performed because of possible lymph node metastasis of the splenic hilus or infiltration/metastasis of the spleen. The purpose of this study was to investigate the frequency of lymph node metastasis to the splenic hilus and metastasis to the spleen in proximal gastric carcinomas.

Methods: In a morphologic study, the frequency of lymph node metastasis to the splenic hilus in 112 patients with proximal gastric cancer was investigated with particular emphasis on its correlation with established clinicopathological characteristics and classifications. Seventy-seven gastrectomy specimens were obtained from men and 35 from women. Patients ranged in age from 20 to 89 years (median 60 years). All patients underwent a potential curative resection (RO resection) with total gastrectomy and pancreas-preserving splenectomy. None of the patients had been treated preoperatively with cytotoxic drugs or radiation.

Results: A mean number of three lymph nodes (range 0-8) in the splenic hilus was found in each specimen. The incidence of lymph node metastasis of the splenic hilus was 9.8% (n=11). Lymph node metastasis was only observed in advanced proximal gastric cancer (UICC IIIb/IV) located at the greater curvature and in Borrmann type III/IV cancer with advanced lymph node metastasis. An infiltration of the spleen was seen only in two cases with advanced stages of gastric carcinoma (stage IV).

Conclusions: Based on our data lymph node metastasis to the splenic hilus is rarely observed in proximal gastric cancer and only found in advanced cancer (UICC IIIb/IV) especially in tumors of the greater curvature and of Borrmann type IV cancer.
