BACKGROUND: The incidence of proximal gastric third carcinoma (PGC) has been rising in recent years. Classification and surgical therapy remain controversial. METHODS: Between May 1986 and October 1997, 532 patients were operated for primary gastric carcinoma. All patient data were analyzed retrospectively comparing findings in patients with PGC and those with distal gastric carcinoma (DGC). RESULTS: Two hundred fifty patients had a PGC, and 282 patients had a DGC. The rate of RO resections was 79.3% for PGC and 81.6% for DGC. In 93.9% of the patients with PGC total gastrectomy was performed; for DGC total gastrectomy was done in 74.5% of patients. Postoperative morbidity and mortality were 29.2% for PGC and 23.8% for DGC, and 3.2% for PGC and 3.5% for DGC, respectively. Patients with advanced tumor stages (stage III and IV) were more common in the PGC group (73.3% vs. 53.6% in DGC). After RO resection, the 5-year survival rate was 33.2% for PGC and 59.7% for DGC. CONCLUSIONS: There was no significant difference between the rates of RO resections for PGC and DGC. Total gastrectomy can be performed with low postoperative morbidity and mortality. PGC and DGC represent the same tumor entity, and prognosis is similar, but due to more advanced tumor stages, the long-term survival is worse for patients with PGC than for those with DGC. Left retroperitoneal lymphadenectomy may be indicated for PGC.
