Background: In gastric cardia cancer (GCC), the spleen is usually removed when the tumor is resected. This allows thorough lymph node dissection in the splenic hilus. However, the long-term effect of splenectomy on patient survival is controversial. The purpose of this study was to investigate the effect of spleen preservation on survival following radical resection for gastric cardia cancer.

Methods: We reviewed the records of 116 GCC patients (Siewert types II and III) who underwent radical resection with D2 or D3 lymphadenectomy between July 1994 and December 2003. Survival status was ascertained in December 2004 and data from 108 patients were analysed. Of these 108 patients, 38 underwent splenectomy and 70 had splenic preservation. Clinicopathological features and prognostic data of the splenectomy(+) and splenectomy(–) groups were compared.

Results: Seventy-four patients (68.5%) had lymph node involvement; 18 (16.7%) had involvement of nodes in the splenic hilus. Postoperative morbidity in the two groups was similar. Overall 5-year survival was higher in the splenectomy(–) group than the splenectomy(+) group (38.7% versus 16.9%, P =.008). Multivariate regression indicated that tumor invasion (P =.009) and lymph node metastasis (P = .001) were independent prognostic factors – they predicted decreased survival – with or without splenectomy. Although splenectomy was be associated with lower survival, it was not an independent prognostic factor (P =.085).

Conclusions: Splenectomy does not improve survival of patients who undergo curative resection for gastric cardia cancer. Thus, the spleen should be preserved in patients without direct cancer invasion of the spleen.
