This study examined the influence of nodal harvest and the proportion of positive nodes on survival in 59 patients with adenocarcinoma of the distal esophagus and esophagogastric junction undergoing esophagectomy with curative intent. A total of 754 lymph nodes were harvested (median 13, range 0-28). Two hundred and twenty-eight positive nodes were found on histology (median 4, range 1-23) in 43 (79%) patients with a higher incidence from T3/T4 than T1/T2 lesions (P < 0.003). Overall 1- and 3-year survival rates were 73% and 47% respectively. Node positivity increased with increased total nodal harvest, but was not influenced by the site of tumors or surgical approaches. There was no survival benefit for patients with <20% over >20% nodal positivity (P=0.31). Only negative lateral resection margin emerged as a significant factor in both univariate (P < 0.01) and multivariate analysis (P < 0.05). We conclude that the degree of nodal positivity in adenocarcinoma is less important than resection margin status as a prognostic factor.
