Poor Prognosis of Advanced Gastric Cancer with Metastatic Suprapancreatic Lymph Nodes

Abstract

Whether gastrectomy with D2 lymphadenectomy improves survival of patients with advanced gastric cancer (AGC) remains controversial. Few studies have described the pathological features of AGC with metastatic suprapancreatic lymph nodes (LN), which are the target of D2 lymphadenectomy. This study therefore aims to clarify the prognosis and clinical pathological features including the number and location of metastatic LN in AGC with metastatic suprapancreatic LN. 406 patients with AGC, who underwent gastrectomy with D2 lymphadenectomy from 1982 to 2007 at Oita University, were reviewed retrospectively with regard to presence or absence of metastatic suprapancreatic LN. The pathological factors associated with AGC with metastatic suprapancreatic LN were examined by univariate and multivariate analysis. Of 362 patients with AGC, 78 had suprapancreatic LN metastasis (21.5 %), differing significantly in terms of presence of vascular invasion and having a larger number of metastatic perigastric LN in comparison with only metastatic perigastric LN on univariate analysis. According to multivariate analysis, they were associated with presence of vascular invasion and a large number of total metastatic LN (more than two; N2≤). The overall 5-year survival rate of the AGC with perigastric LN metastasis (station 1–7) group was 37.9 % and of the AGC with suprapancreatic LN metastasis group was 12.8 %. There were significant differences in each group (P < 0.05). Patients with AGC with metastatic suprapancreatic LN had a large number of total metastatic LN and poor prognosis, suggesting that it may be a systemic disease.
