BACKGROUND: No multivariate study has assessed the independent prognostic role of endoscopic ultrasonography (EUS) in esophageal cancer, even when considering computed tomography (CT). OBJECTIVE: To evaluate the prognostic value of EUS in esophageal cancer before exclusive or preoperative radiochemotherapy. METHODS:From 1993 to 1999, the FFCD 9102 study enrolled 444 patients who had cancer of the thoracic esophagus, stages T3-4, N0-1 and M0 on CT. The patients received two sessions of chemotherapy in addition to radiotherapy. The 259 patients with objective response and no contraindications for further treatment were randomized to undergo surgery or to continue with radiochemotherapy. EUS was performed in 174 patients enrolled in the trial (mean age: 59 years). Tumor characteristics and lymph node status were prospectively recorded. A Cox statistical model was used to identify any predictive prognostic factors among the clinical, EUS and CT data. RESULTS: In the multivariate analysis, three factors were associated with a poor prognosis: inability to ingest solid food (OR: 1.98; P=0.0008); more than three neoplastic subdiaphragmatic lymph nodes (LN) on EUS (OR: 2.41; P<0.0045) and age>65 (OR: 1.53; P<0.056). Their prognostic value persisted after adjustment for type of treatment given. Two- and five- year survival rates were 21.5 and 10.5%, respectively, in the presence of three neoplastic subdiaphragmatic LN, and 43 and 30%, respectively, in all other cases. CONCLUSION: Degree of dysphagia, age and presence of neoplastic subdiaphragmatic LN on EUS were independently predictive of the prognosis for locally advanced esophageal cancer. EUS results should be taken into account in future trials.
