Presented at the Forty-seventh Annual Meeting of the Southern Thoracic Surgical Association, Marco Island, FL, Nov 9–11, 2000.

Background. Esophageal cancer patients with M1a disease are reported to have poor survival. We hypothesized that patients with celiac lymph node metastases (CLN) identified by endoscopic ultrasonography (EUS) would predict a cohort with significantly worse survival postoperatively. Accurate preoperative identification of this group will facilitate future adjuvant studies.

Methods. During the study period, 211 patients with esophageal cancer underwent EUS staging. Patients with evaluable celiac axis (n = 182) were included in this study. Survival of patients with and without CLNs was compared and the factors affecting overall survival were assessed. A subgroup analysis based on CLN status was performed in the subgroup of patients who underwent surgical procedures.

Results. Follow-up data was available in 91.2% (166 of 182) of the patients. As staged by EUS, T1, T2, T3, and T4 tumors accounted for 9.3%, 11.5%, 56%, and 21% of the cases, respectively. At least one CLN was imaged by EUS in 40% (72 of 182). The 5-year survival in patients with CLNs detected by EUS was 13% (95% confidence interval, 5% to 21%) compared with 30% (95% confidence interval, 21% to 40%) in patients with no CLNs detected by EUS (p = 0.007). In the subgroup of patients who underwent surgical procedures (n = 68), patients with CLN involvement had worse survival compared with those who did not have malignant involvement of CLNs at the time of their operation (median survival 39.8 versus 13.8 months, p = 0.0008). In a Cox proportional model, adjusting for race and the type of therapy, patients with CLN involvement or advanced EUS American Joint Committee on Cancer stage were more likely to have worse survival (p < 0.05)

Conclusions. EUS base line findings correlate with long term survival in patients with esophageal cancer. Patients with M1a disease as identified by EUS had a significantly worse postoperative survival when compared with non-M1a patients. This cohort of patients will be ideal for the study of induction therapy since the effect of down staging can be assessed before operation.
